CHAPTER - I INTRODUCTION Apparel and Textile industry in India is the largest employer after agriculture. It provides direct employment to 35 million people and another 56 million are engaged in related activities. Around 14% of industrial production of the country is contributed by the sector. Indeed the apparel sector place a major role in Indian economy and also in foreign exchange earnings. Apparel exports contribute approximately 9% in India’s total exports earnings and accounts for about 4% of world trade in textiles and apparels. It is pertinent to mention that the apparel sector predominantly consist of Small and Medium Enterprises (SMEs). With the abolition of quota regime under WTO and opening of markets, there is competition from many countries to retain the existing global market share and also look for new markets. India has set a target under 11th plan to earn $ 50 billion through exports of textiles and apparels. To reach the target Indian apparel industry has to work on many fronts to be successful in a totally competitive international environment particularly focusing on factors like development of skilled human resource, quality and productivity, design development and product diversification and improving lead time and pricing, effective marketing management. Indian Small and Medium Enterprises (SMEs) alone cannot attain competitiveness without the support of likeminded international partners like German Technical Co operation (GTZ) to enhance the competitiveness of SMEs. Indeed GTZ is committed under SME Financing and Development Project for the development of apparel sector and identified it as the priority sector for intervention. Against the back ground the GTZ has undertaken the task of MSMEs competency building through business development services in Readymade garments cluster at Hyderabad with the support of Orient Craft Fashion Institute of Technology (OCFIT) particularly in preparing manual for sewing machine operators. In furtherance of the same, OCFIT with a view to assist development of readymade garment cluster in Hyderabad focusing around 50 RMGs (16 micro units, 14 small units and 20 medium and large units), studied their working pattern, commercial viability and prepared this manual to assist the sewing machine operators. Indeed this manual is prepared based on best international sewing practices world over with a focus on exports of readymade garments from India through SMEs.

1. INVENTION OF THE SEWING MACHINE The democratization of fashion began with the invention of the sewing machine, which turned a handicraft into an industry. The sewing machine made the mass production of clothing possible. In 1829, a French tailor named Thimmonier patented a wooden chain-stitch sewing machine, but all existing models were destroyed by rioting tailors who feared for their jobs. Walter Hunt, an American, developed a sewing machine in 1832 but failed to patent it. Thus, the man who is usually credited with its invention is Elias Howe, who patented his in 1846. All of Howe’s machines were run by hand. In 1859, Isaac Singer, whose name has become a household word because of his mass production of the sewing machine. He developed the foot treadle, an improvement that left the hands free to guide the fabric, and mass-produced these machines. Singer spent $1 million a year on sales promotion and, by 1867, was producing a thousand machines per day (Electrically powered models were not available until 1921). To save time and to keep control over production, entrepreneurs brought workers and machinery together in factories. This caused many people in search of work to move to the cities where the factories were located. In 1849, when the Gold Rush attracted thousands of men in California in search of gold, a 20year old Bavarian immigrant by the name of Levi Strauss opened a dry goods store in San Francisco. In 1873 he began to manufacture long-wearing pants with riveted pockets, using a tough cotton fabric called serge de Nimes. (Loomed in Nimes, France), later shortened to denim. They are an item of wearing apparel that has remained basically the same for nearly 150 years. Another early use for sewing machines was to make Civil War uniforms. The Union army recorded the chest an height measurements of more than a million soldiers to come up with the first standardization of sizes. After the war, sewing machines and uniform sizing promoted the mass production of everyday men’s wear.

2. HISTORY OF SEWING MACHINE Historians of the early days of the sewing machine can argue for hours over the simple matter of who invented what is, in many ways, one of the most important machines ever devised. The story really starts in 1755 in London when a German immigrant, Charles Wiesenthal, took out a patent for a needle to be used for mechanical sewing. There was no mention of a machine to go with it, and another 34 years were to pass before Englishman Thomas Saint invented what is generally considered to be the first real sewing machine. In 1790 the cabinet maker patented a machine with which an awl made a hole in leather and then allowed a needle to pass through. Critics of Saint's claim to fame point out that quite possibly Saint only patented an idea and that most likely the machine was never built. It is known that when an attempt was made in the 1880s to produce a machine from Saint's drawings it would not work without considerable modification. The story then moves to Germany where, in around 1810, inventor Balthasar Krems developed a machine for sewing caps. No exact dates can be given for the Krems models as no patents were taken out. An Austrian tailor Josef Madersperger produced a series of machines during the early years of the 19th century and received a patent in 1814. He was still working on the invention in 1839, aided by grants from the Austrian government, but he failed to get all the elements together successfully in one machine and eventually died a pauper. Two more inventions were patented in 1804, one in France to a Thomas Stone and a James Henderson -- a machine which attempted to emulate hand sewing -- and another to a Scott John Duncan for an embroidery machine using a number of needles. Nothing is known of the fate of either invention. America's first real claim to fame came in 1818 when a Vermont churchman John Adams Doge and his partner John Knowles produced a device which, although making a reasonable stitch, could only sew a very short length of material before laborious re-setting up was necessary. One of the more reasonable claimants for inventor of the sewing machine must be Barthelme Thimmonier who, in 1830, was granted a patent by the French government. He used a barbed needle for his machine which was built almost entirely of wood. It is said that he originally designed the machine to do embroidery, but then saw its potential as a sewing machine.

Page | 9

Unlike any others who went before him, he was able to convince the authorities of the usefulness of his invention and he was eventually given a contract to build a batch of machines and use them to sew uniforms for the French army. In less than 10 years after the granting of his patent Thimmonier had a factory running with 80 machines, but then ran into trouble from Parisian tailors. They feared that, were his machines successful, they would soon take over from hand sewing, putting the craftsmen tailors out of work. Late one night a group of tailors stormed the factory, destroying every machine, and causing Thimmonier to flee for his life. With a new partner he started again, produced a vastlyimproved machine and looked set to go into full-scale production; but the tailors attacked again. With France in the grip of revolution, Thimmonier could expect little help from the police or army and fled to England with the one machine he was able to salvage. He certainly produced the first practical sewing machine, was the first man to offer machines for sale on a commercial basis and ran the first garment factory. For all that, he died in the poor house in 1857. In America a quaker Walter Hunt invented, in 1833, the first machine which did not try to emulate hand sewing. It made a lock stitch using two spools of thread and incorporated an eye-pointed needle as used today. But again it was unsuccessful for it could only produce short, straight, seams. Nine years later Hunt's countryman, John Greenough, produced a working machine in which the needle passed completely through the cloth. Although a model was made and exhibited in the hope of raising capital for its manufacture, there were no takers. Perhaps all the essentials of a modern machine came together in early 1844 when Englishman John Fisher invented a machine which although designed for the production of lace, was essentially a working sewing machine. Probably because of miss-filing at the patent office, this invention was overlooked during the long legal arguments between Singer and Howe as to the origins of the sewing machine. Despite a further flurry of minor inventions in the 1840s, most Americans will claim that the sewing machine was invented by Massachusetts farmer Elias Howe who completed his first prototype in 1844 just a short time after Fisher. A year later it was patented and Howe set about trying to interest the tailoring trade in his invention. He even arranged a competition with his machine set against the finest hand sewers in America. The machine won hands down but the world wasn't ready for mechanized sewing and, despite months of demonstrations, he had still not made a single sale. Desperately in debt Howe sent his brother Amasa to England with the machine in the hope that it would receive more interest on the other side of the Atlantic. Amasa could find only one backer, a corset maker William Thomas, who eventually bought the rights to the invention and arranged for Elias to come to London to further develop the machine.

Page | 10

The two did not work well together, each accusing the other of failing to honor agreements and eventually Elias, now almost penniless, returned to America. When he arrived home he found that the sewing machine had finally caught on and that dozens of manufacturers, including Singer, were busy manufacturing machines -- all of which contravened the Howe patents. A long series of law suits followed and were only settled when the big companies, including Wheeler & Wilson and Grover & Baker, joined together, pooled their patents, and fought as a unit to protect their monopoly. Singer did not invent any notable sewing-machine advances, but he did pioneer the hirepurchase system and aggressive sales tactics. Both Singer and Howe ended their days as multi-millionaires. So the argument can go on about just who invented the sewing machine and it is unlikely that there will ever be agreement. What is clear, however, is that without the work of those long-dead pioneers, the dream of mechanized sewing would never have been realized.

CHAPTER-III

SELECTION CRITERIA FOR SMO TRAINEES

Page | 23

The Candidate for the SMO Training Programme must have the minimum qualification of 8th Standard. The Candidate’s age preferably should be between 18 to 25 years. The objective of the program is to meet the skill requirements of the apparel industry and to create gainful employment opportunities for rural BPL families in apparel industry. So, keeping in view the requirements of the industry, the candidate for the SMO Programme has to pass through the following tests: 1. PEG BOARD TEST

The Peg Board Test is conducted to know the hand movement of the candidate. The Purdue Pegboard has been used extensively for various applications. It has two types of activity: one measures gross movements of the hands, fingers, and arms, and the other measures assembly or fingertip dexterity. The Peg Board Test consists of a rectangular board that holds cylindrical pegs. The pegs are approximately two inch (2.5 cm) in height, and are colored red on one side, black on the other. Two tests were chosen for this research. The peg board test requires subjects to transfer the pegs from one hole in the tray to another. The peg board test requires subjects to pick up a peg, transfer it to the other hand while turning it over, and replace it with the opposite side facing up. The operator will be given 80 sec of time to complete it. The operator has to complete the exercises given in the given span of period.

Page | 24

2. COLOR BLINDNESS TEST The colour blindness test used test to check color vision deficiencies. There are different sets available which are often used for pilot, police officer and other job recruitments, where perfect colour vision is a precondition. This is a test plate in which everyone should see a "12".

This plate is designed to separate the type of color defectives and the level to which they are observed. Most will see the number "26" clearly while some will only see a "2" or a "6" or no numerals at all.

Can you trace a line from one "X" to the other? Someone with normal color vision will trace an orange/brown purple line and those with a slight deficiency will follow a different path.

Page | 25

Some of the Examples are:

The operator will be shown 10 figures. Each carries 5 sec of time. The operator must be able to recognize the Letter or Number which is in the Figure in the given span of time.

Page | 26

3. VISUAL DEXTERITY TEST Example: 8 5 3 2 7 1 6 9 4 10

Practice:

Visual Dexterity test is the crucial one which plays major role in knowing the Eye Coordination of the operator. Eye coordination is a crucial skill involving how effective we are at translating what our eyes see into appropriate physical responses, such as anticipating the motion of a line in its way so that we could find out the exact destiny of the line. The operator will be given two exercises; each carries 30 sec of time to complete it. The operator has to complete the exercises given in the given span of period.

Page | 62

A. Thread the Machine and Draw up the Bobbin Thread 1. Turn the machine off and remove your feet from the treadle. If there is no needle in the machine, run the machine out. Then insert a new needle. Check to be sure there is no lint or dust between the tensions discs or in the thread guide. 2. Raise the thread take-up lever to its highest point. 3. Place the thread on the thread stand. Then pass the thread over the guide at the top of the thread stand and through the hole in the spool pin(s). 4. Guide the thread into the right (or top) hole of the needle-thread retainer. Then, guide it through the center hole and, finally the bottom (or left) hole. 5. Guide the thread between the tension discs. Pull it into the check spring and under the slack thread retainer or vertical bar. 6. Guide the thread from right to left into the eye of the take-up lever. 7. Guide the thread through the remaining guides. The last thread guide is located directly above the long groove on the needle. 8. Trim the thread end as needed and thread it into the eye of the needle from left to right. Note: The thread always threads from the long eye or groove on one side of the needle to the short eye on the other 9. Pull the thread end about 3” (15cm) and hold the thread loosely in your left band. 10. Release the brake and turn the hand wheel so that the needle moves down and up again to catch the bobbin thread. If the thread doesn’t come up, check the machine threading. Remove the bobbin case, rethread, and insert again Note: If you continue to turn the hand wheel, you may create a thread jam. 11. Pull the needle thread taut to bring the bobbin thread up through the needle hole. 12. Pull both threads between the prongs or toes of the foot, and then under the presser foot to the back of the machine leaving a 5” (15cm) tail. 13. Draw the thread path for a lockstitch machine.

B. Threading the bobbin case

1. Removing the bobbin case Raise the bobbin case latch to remove the bobbin case 2. Threading the bobbin case Pass the thread through the slit 1 in the bobbin case and route it under tension spring 2 Hold the large of the bobbin case and set the bobbin case into the hook.

Place the bobbin in the case taking care of the winding direction of the thread.(The bobbin should turn in the direction of arrow B when the thread is pulled in the direction of arrow A)

Page | 64

C. Bobbin winding

1) Route the thread in the order of A, B, and C, and then wind it round the bobbin several times. 2) Set bobbin presser 1 down to make the winder come in contact with the belt. 3) Adjust adjustment screw 2 of the amount of bobbin thread to be wound round the bobbin so that the bobbin is wound with thread about 80%.Turn the adjustment screw 2 clockwise to increase the bobbin thread amount or counterclockwise to decrease it. 4) If thread is wound unevenly, move winder tension adjust base 3 to the right or left until it is correctly positioned. 5) The moment the bobbin has been wound up, the bobbin presser is released, and the bobbin winder will stop automatically.

C. Machine adjustments and control Adjusting the Stitch Length Regulator The stitch length regulator controls the distance that the feed dogs move the material to the back of the machine to make a single stitch. On newer machines, the stitch length regulator is often a large knob or a lever on the front of the machine, making It easy to regulate. On older machines however, the stitch length regulator is more difficult to locate and reset and ft rarely has a guide indicating the setting. On most newer machines, the length of each stitch is Indicated In millimeters (mm). On other machines, the number of stitches per inch(SPI) is Indicated. This latter method is easier to use when adjusting the stitch length regulator. These general directions can be used for most machines, however, when a machine manual is available, ft is always wise to review the directions in it. 1. Begin with the power switch on arid the machine unthreaded. Place a piece of paper under the foot and stitch a straight line about 3” long. 2. Remove the paper from the machine. Mark off 2”(5cm), placing the first mark midway between two needle perforations. Begriming at the first perforation following the first mark, count the number of perforations between the two marks. If the second line is between two perforations, add an additional perforation. 3. To determine the number of stitches per inch (SPI), divide the number of perforations by two - the number of inches stitched. There are 20 perforations between the two marks, there are 10 SPI. 4. To determine the number of stitches per centimeter (SPO), divide by five - the number of centimeters stitched. If there are 20 perforations between the two lines, there are 4 SPC. 5. To determine the number of millimeters in a stitch, divide the number of millimeters in a stitch, divide the number of millimeters (10) In a centimeter by the number of SPO (stitches/cm). If there are 4 SPC, each stitch Is 2.5mm (4 divided by 10) long. 6. Set the stitch length to 2.5mm or 1OSPL. Stitch 3”. Mark off a 2” section, then count the stitches to confirm the accuracy of the setting. Repeat to set the stitch length to 1.5mm (17 SPI), 2 (12 SPI). 3mm (8.8SPI), and 4 mm (6 SPI). Record your measurements In Table.

If there is too much pressure on the tension discs, not enough thread is fed into the stitching and the tension is right. The material puckers the seam is strained, and the stitches break. If there is too little pressure, too much thread is fed, the tension is too loose, and the seam is loose and weak. When the tension on the top, or needle, thread is too tight or the tension on the bottom or bobbin thread is too loose, the top thread lies along the surface of the material and the bobbin thread forms loops on the top.

Page | 97

When the tension on the top, or needle, thread is too loose or the bottom, or bobbin, thread is too tight, the bottom thread lies along the underside of the material and the top thread forms loops on the underside.

Adjusting the tension The tension of the stitch is regulated by two controls: the upper tension regulator and the bobbin case tension screw. The upper tension regulator is located on the front of the machine and adjusts the tension discs.

The bobbin case tension screw, which is located on the bobbin case controls the tightness of the bobbin case spring. These controls increase or decrease the amount of pressure on the threads as they fed through the machine. Because the structure, texture, thickness, density, and resiliency of the material and the size and type of the thread affect the tension, the tension settings will vary with the material and the thread size and type. Test the tension before beginning a garment or sewing with a different fabric, thread, or machine. 1. Identity the upper tension regulator and the bobbin case tension screw. 2. Set the stitch length for 2 mm (128P1). Turn the upper tension regulator to the right 1/4 to 1/2 turn. 3. Fold one muslin rectangle in half crosswise and stitch on the straight grain about 1/2” from the edge. 4. Examine the stitching to determine whether the stitching is balanced or unbalanced. If the needle tension is tight the needle thread lies flat on the top ply and loops of the bobbin

Page | 98

thread are visible, If the bobbin tension Is tight, the bobbin thread lies flat and the loops of the needle thread are visible.

5. Adjust the bobbin tension first. To determine if it needs an adjustment, place the filled bobbin In the bobbin case. Hold the end of the bobbin thread and jerk the thread slightly. It should drop several Inches. If it slides freely down the thread, it needs more tension; if doesn’t slide, it needs less. a. If it needs an adjustment, use a small screwdriver to loosen the screw on the bobbin case. For more tension, turn the screw in small increments and no more than 1/4 turn between tests. b. Caution: The bobbin case screw is very short and will fall out if turned too far. 6. To adjust the needle thread tension turn the tension regulator to the left to loosen it; turn it to the right to tighten. 7. Adjust the tensions only as needed until the stitch is balanced. 8. Experiment with stitching on a variety of fabrics.

Machine Maintenance In the apparel industry, a clean, well-oiled machine is essential for safety and good performance, the same is true in the classroom. Generally cleanliness is the responsibility of the operators, including students who use the machines. The machines are given a quick cleaning after every eight hours of operation and a thorough cleaning once a week. When sewing materials that produce a lot of lint, the machines are cleaned more frequently. Machine maintenance is also important in preventing stitching faults. Although stitching faults can be caused by the material, machine, or operator, most can be corrected by cleaning the machine, rethreading it, and/or changing the needle. In most plants, a quick cleaning is done by the operators once a day, but the responsibility for the more thorough cleaning varies from plant to plant. In some factories, it is done by the operators on Friday afternoon. In others, it is done by a mechanic - often, when the operators are not working.

Cleaning the Machine When cleaning the machine, clean everything - the machine mechanism, machine table and stand, your tools, work station area, and even your hands - to avoid soiling the materials being sewn, prevent accidents, and avoid wear and damage to the machine. These directions focus on the lockstitch machine, but they can easily be adapted for other machine types.

Materials/Supplies    

Paint brush (1/2” wide) Clear disposable cloth or clean rag Screwdriver Sewing machine manual (when available)

Page | 99

 Air hose or industrial vacuum cleaner (when available)

Caution: Before cleaning any machine, turn off the machine and run it out. 1. Open the slide and remove the bobbin case, and then remove the throat plate. Occasionally remove the face plate from the left end of the head. 2. Brush or blow away any lint, dust, or loose threads in the area around the feed dogs and rotary hook or shuttle. Do not use anything hard, such as a screw driver or scissor points, to remove the lint. When cleaning the over lock machine, open the cloth plate and looper cover to blow out any lint in those areas. On the blind stitch machine, open the plate to expose and clean the area around the spreader. 3. Turn the hand wheel manually to expose any areas that might have been hidden initially; brush again. 4. Carefully tilt the machine head back until the head rests on the post on the back of the table. 5. Brush out any lint, dust, or threads in the lower part of the machine. Use a rag to remove any lint on the machine’s mechanism, excess oil in the pan, and, if appropriate, the oil pump screen. 6. If the machine is not self-oiling, consult the manual for oiling directions. If the manual is not available, place one drop of oil on each moving part on the lower mechanism. 7. Press the knee lift to the right and lower the machine head into position. 8. Replace all plates and screws. 9. Oil the upper mechanism by placing a c p of oil in each oil bole 10. Replace the bobbin case. 11. Check the needle to be sure it is clean and the eye is not clogged. 12. Replace the needle if necessary. 13. Wipe away any excess oil or dust on the head, machine bed, thread stand, motor, table and stand. 14. If there is lint between the tension discs and in the thread guides, use thread to floss the tension discs and remove any lint. 15. If you have oiled the machine, sew on a few scraps to remove any excess oil. 16. Wash your hands after cleaning and oiling the machine. 17. At the end of the day, put a piece of stitching patch under the foot, lower the foot, cover the machine, and pick up any trash.

CHAPTER - VII

NEEDLE

Page | 101

1. SELECTION OF NEEDLE Basic Skills To use Industrial machinery efficiently, you should be able to select and set a needle; adjust the stitch length regulator, pressure regulator, and knee lift; Identify balanced tension and adjust as needed; and select appropriate thread.

Setting the Needle In the apparel industry, there are literally thousands of different machines, each requiring a different needle type. On most newer machines, the needle type for that particular machine is identified on the machine head. However, each needle manufacturer identified its needles in a different way; the needles for the same type of system may have several different names or numbers, depending on the manufacturer. Directions: 1. Begin with the power switch off. Hand wheel until the needle moves machines; you will turn the counterclockwise - the direction operating. 2. Use a screwdriver or Allen wrench to loosen the screw in the needle bar just enough to release the needle.

Changing the needle 3. Remove the needle from the needle bar. If the needle is broken, remove any broken parts that may have dropped into the machine. If part of the shank remains in the needle bar after the screw is loosened, tap the needle bar with the handle of the screwdriver. If it still does not Fall out, turn the machine on, raise the presser foot, and stitch slowly until the vibration causes the needle to drop out.

Page | 102

4. Dispose of the needle safely. 5. Note To make a safe container for disposing needles; punch a small hole in the top of a discarded film container. 6. Check the new needle for straightness by rolling it on the machine table. If the needle is straight, the blade of the needle will remain parallel to the table surface when it is rolled. Check the needle point for burrs by running your fingertip over the point. 7. To check the needle and thread compatibility, thread the needle with a short length of thread. Hold the thread taut at each end in vertical position. The needle should spin slowly dawn and around the thread. If It slides slowly down and around the thread. If it slides too quickly or does not slide at all, try a different size needle or select another thread. 8. Use your thumbnail to locate the long groove on the needle. This will help you to set the needle correctly. 9. Hold the new needle between your right thumb and forefinger at the base of the shank where the groove begins. 10. Locate the last thread guide on the needle bar. On straight-stitch machines, the guide is generally to the left of the needle. Insert the needle into the needle bar so that the groove is facing the side with the last thread guide (left) and the eye is in line with the arm of the machine. Check to be sure the needle is inserted into the needle bar as high as possible. 11. Tighten the needle bar screw. 12. Tighten the machine and stitch slowly. If the needle is positioned correctly, there will be no skipped stitches and no unexpected noises. If it is not set properly, remove the needle and reset it.

Reasons to Change a Needle There are many reasons for changing the needle. Some of them are: 1. 2. 3. 4. 5. 6.

The needle is damaged: bent, burred, or broken. The needle is dull and makes a popping sound when stitching The thread breaks frequently during stitching. The machine is skip stitching. A different thread size is required. A different fabric is sewn with a different weight, thickness and construction.

Page | 103

2. PART OF THE MACHINE NEEDLS 1. Butt: A small pyramid at the upper end of the shank. It is designed to make a single-point contact with the hole in the needle bar. 2. Shank: The upper end of the needle that is held in the needle bar by the needle screw. The shank is usually round, but it can have one or two flat sizes. Designed to support and stabilize the needle blade, the diameter of the shank is usually larger than the diameter of the blade. 3. Shoulder: The beginning of the shank just above the needle blade. 4. Blade: The thin section of the needle that extends from the shank to the eye. It is easily bent and should be examined for straightness periodically. 5. Scarf (needle scarf, clearance above the eye, clearance cut, or spot): A small indentation above the eye that permits the hook or looper to pick up the thread loop. On some needles, the scarf is elongated and/or deeper to ensure that the needle thread loop will be large enough to prevent skip stitching. 6. Land: A small hump on the blade immediately above the eye. Used instead of a scarf, its purpose is to enable the needle thread to make a larger loop and form a stitch. 7. Eye: An opening in the needle blade at the lower end of the long groove that carries the thread into the material to the hook or looper to make a stitch. The size of the eye is proportional to the diameter of the blade. 8. Point: The tapered end. It is often considered the most critical aspect of the needle. The most common needles have a round point, a ballpoint, or a cutting point as shown on page 44. Generally round points and ballpoints’ are used for woven and knit fabrics because they can penetrate the fabric by spreading the fibers or deflecting the yarns without damaging them. By contrast, needles with cutting points are used for leather. 9. Tip: The part of the needle that pierces the material. 10. Needle groove (long groove): A g channel on the black it is located on the side on which the need dread enters the eye a provides a Protective guide for the thread when the needle is rising and the needle- thread loop is enlarging.

Page | 104

11. Short groove: A short channel immediately above the needle eye. Located on the side opposite the long groove, it is a guide for the needle thread and protects it from abrading when passing through the material.

Needle Selection Once the needle system type Is determined, the needle selection - its needle point and size depends primarily on the characteristics of the fabric, but also on the thread, seam type, and stitch type. Needle point The needle point is determined by the fabric weight and its structure. Round points have a conical shape designed to spread the yarns without breaking them; they are used for most woven and many knitted materials. Ballpoint needles have a rounded point and range from light to heavy. They are generally used for knits and stretch fabrics and sometimes for button sewing because they center most misaligned buttons and do not cut existing stitches. Cutting points have sharp cutting edges; they are used on leather, suede, and neoprene.

Needle Size The needle size can be as small as 60 (0-6mm) or as large as 250 (2.5 mm). The metric size describes the diameter of the needle blade in hundredths of a millimeter. The needle size is determined by the thread size. If the needle is too fine, it will abrade the thread bend, break, affect the loop formation, and cause skipped stitches. if it is too course, it will damage the fabric, produce an unattractive seam, cause the seam to pucker, affect the loop formation, and cause skipped stitches. Generally the best choice is the smallest size that will not skip stitches. Round point

3. STANDARD NEEDLES The configuration of these needles is based on the particular fabric to be sewn. Universal needle

Ballpoint and stretch needles

Uses: Safest needle choice for most fabrics.

Uses: Ballpoint needle for heavier, looser sweater knits; stretch needle for highly elastic fabrics, like Spandex, or Lycra.

Configuration: Has slightly rounded point and elongated scarf to enable almost foolproof meeting of needle and bobbin hook. Troubleshooting: When fabric is not medium-weight woven, consider needle specifically suited to fabric. For example, size 18 universal needle works on heavy denim, but size 18 jeans needle works better.

Configuration: Both have rounded points that penetrate between fabric threads rather than pierce them. (Stretch-needle point is slightly less rounded than ballpoint.) Troubleshooting: Test-stitch knits with ballpoint, stretch, and universal needles to see which doesn't cut yarn and yields best results. If ballpoint skips stitches, try stretch needle.

Page | 106

Microtex

and

sharp

needles

Uses: Sewing microfiber, silk, synthetic leather; precisely stitching edges; and heirloom sewing. Configuration:

Has

an

acute

point.

Leather needle Uses: Excellent for sewing natural leather. Configuration: Has slight cutting point (almost like an arrowhead).

Troubleshooting: Essentially trouble-free, but fabric may require a Teflon, roller, or even/dual-feed presser foot.

Troubleshooting: On synthetic leather, unless it's very heavy synthetic, cuts rather than pierces stitch hole and can tear leather. Most synthetic leathers require Microtex or sharp needle.

Denim (jeans) needle

Handicap/self-threading needle

Uses: For heavyweight denim, duck, canvas, upholstery fabrics, artificial leather, and vinyl.

Uses: Enables easier threading for sewers with vision problems.

Configuration: Has deeper scarf, acute point, and modified shaft to sew without pushing fabric down into needle-plate hole. Goes through fabric and meets bobbin hook better on dense woven fabrics. Troubleshooting: If stitches skip when sewing very heavy fabrics, try larger needle and sew more slowly or walk needle through fabric (by turning hand crank).

Configuration: Universal needle with slipin threading slot at the eye. Troubleshooting: Always pull sewn piece back away from needle before cutting thread so needle doesn't unthread. Needle works well on woven fabrics, but may occasionally snag knits, so test-sew to check for fabric and needle compatibility.

Decorative needles The configuration is designed to wed thread to fabric for surface embellishment.

Page | 107

Topstitching needle

Embroidery needle

Uses: Topstitching.

Uses: Machine embroidering or embellishing with decorative thread.

Configuration: Has extra-acute point, extra-large eye, and large groove for heavy thread. Troubleshooting: Use smallest size needle that accommodates your thread to avoid punching large holes in fabric.

Configuration: Has light point (neither sharp nor ballpoint) and enlarged eye to keep decorative threads from shredding or breaking, and prevent skipped stitches. Troubleshooting: If thread still shreds on dense or heavily stitched design, use larger size needle or Metallica needle.

Metallic needle

Quilting needle

Uses: Sewing with decorative metallic threads.

Uses: Piecing, quilting, and stippling.

Configuration: Has universal or standard point; large, elongated eye; and large groove to allow fragile metallic and synthetic filament threads to flow smoothly. Troubleshooting: Metallic threads are very sensitive to problems in machine: Tiniest burr on thread path or needle can cause problems.

Configuration: Has special tapered shaft to prevent damaging fabrics when stitching multiple layers. Troubleshooting: Move fabric smoothly without pulling on needle when freemotion stitching to prevent breaking needle.

Special-purpose needles These needles are used only with front-to-back threading machines with zigzag features. Make sure your throat-plate needle hole is wide enough to accommodate needle's width, and zigzag width function is set at zero to prevent sideways movement.

Page | 108

Hemstitch (wing) needle

Twin (double) needle

Uses: Hemstitching or heirloom embroidery on linen and batiste.

Uses: Topstitching, pin tucking, and decorative stitching.

Configuration: Has fins on sides of shank to create holes as you sew.

Configuration: Two needles on single shaft produce two rows of stitches. Measurement between needles ranges from 1.6mm to 6mm, and needles come with universal, stretch, embroidery, denim, and Metallica points.

Troubleshooting: Stitch is more effective when needle returns to same needle hole more than once. If needle pushes fabric into needle hole, put stabilizer under fabric.

Troubleshooting: Be sure throat plate allows for distance between needles.

Triple needle

Spring needle

Uses: Same uses as for double needle.

Uses: Free-motion stitching with dropped feed dogs.

Configuration: Cross bar on single shaft connects three needles to sew three stitching rows. Comes with universal point in 2.5mm and 3mm widths. Troubleshooting: Same as for double needle.

Configuration: Has wire spring above point to prevent fabrics from riding up onto needle, eliminating need for presser foot. Troubleshooting: Before using, practice free-motion stitching with heavy regular needle, paper, and dropped feed dogs. Don't pull paper/fabric; instead gently guide it through stitching. Wear safety glasses for free-motion work, since needles often break.

CHAPTER - VIII SEWING THREAD AND SELECTION CRITERIA

Page | 113

Sewing thread is usually less than 1/1000th of the weight of apparel, but it carries more one half the responsibilities for its performance

THREAD SELECTION FACTORES IN THREAD SELECTION     

Garment design, type, quality, end use, and life expectancy Desired strength and durability Fabric weight and type Stitch and seam type, number of stitches/inch, machine speed, and needle size Cost

Thread Properties Threads are used to form the stitches that hold the fabric parts Together. They can be described by fiber type, constriction, and size

Fiber Type Threads can be made from a single fiber type such as cotton, linen, silk, rayon, nylon, polyester, or rubber or from a combination of fibers such as cotton/polyester.

Natural fiber threads The most common natural fiber used for threads, cotton threads, have excellent sewabllity with little kinking or skip stitching. They are rarely affected by hot needles - a common element of high-speed sewing machines-and even sew well on poorly adjusted machines. Cotton threads dye well, and since they mold to the fabric better than other fibers, they are particularly attractive for topstitched elements. Compared to synthetic threads, their strength and resistance to abrasion is inferior, and they shrink and mildew when wet. Cotton threads are produced with three finishes: soft, glace’ and mercerized. Soft finish threads receive no additional processing except bleaching and dyeing. Used on inexpensive garments, they are relatively inexpensive with good sewabllity but because they have a high shrinkage, seam pucker] fl g is frequently a problem after washing.

Page | 114

Glace’ threads are treated with wax and special chemicals for a hard, glossy finish. They are stronger, more resistant to abrasion, and stiffer than other cotton threads. They are available in a limited color selection and used for gathering and for sewing heavy materials, leather, vinyl, and canvas. Mercerized threads are treated with a caustic solution to create a smooth, strong, lustrous thread. They are frequently used on cotton garments that will be dyed. Linen and silk threads are rarely used in production because of their high cost.

Synthetic threads The most common synthetic threads, polyester and nylon, were developed to perform well on synthetic fabrics and withstand the chemicals and heat of durable press treatments. Compared to cotton threads of the same size, they are stronger, more resistant to abrasion, mildew and ultraviolet radiation, and have less shrinkage.

Combination fibers One of the most common threads in use today is a combination of cotton and polyester, which combines the sew ability of cotton with polyester’s strength and resistance to abrasion.

Thread construction Although there are a variety of thread constructions, most threads used in garments are twisted, core spun, monofilament, or textured. Twisted threads All natural fibers, with the exception of silk, begin with fibers - short lengths of staple, which are twisted together to make a single-ply thread. Then two or more plies are twisted together in the reverse direction to make a sewing thread with a balanced. Twist Without this balance, the thread could not be controlled.

Twist Direct Z - Twist

S - Twist

Most threads are finished with a “Z” or left twist because the action of the lockstitch machine would cause threads with an “8” twist to unwind

Page | 115

One exception is the double-needle lockstitch, which has two bobbins one revolving to the left and one to the right. This type of machine requires threads with both twists. In addition to the natural fibers, polyester, silk, and nylon filaments cut or broken Into staple lengths. Spun polyester thread is one of the most common. Core spun Core spun threads begin with a continuous filament of polyester, which is then wrapped with a cotton or polyester sheath to make a single-ply thread. Then the two to four plies are twisted together to make the sewing thread Cotton/poly threads have the advantage of better sew ability, while poly/poly Threads can be dyed in a one-step process. Monofilament Threads Monofilament is simply a single filament of nylon of polyester. It is stiff, wiry, and unravels easily. It is uncomfortable next to the skin and harsh on machines. Available only in clear, light and dark gray, monofilament Threads are translucent and reflect the fabric’s color. Monofilament threads are used primarily for blind hemming and surging inexpensive garments and Household textiles. Textured Threads Made of multifilament that have been crimp textured or bulked by twisting, crimping, and untwisting, textured threads have a soft Land, good coverage, and elasticity. The most common use of textured threads is in the loopers of over edge and cover stitch machines; however, very fine sizes can be used as needle threads on chain stitch and over edge machines. They can also be used as bobbin threads to add moderate stretch to a lock stitched seam. Thread Size The thread size is dependent on many factors - such as the fabric weight and type, stitch and seam type, machine speed, needle size, end use, and seam strength. Most threads are sized using the Tex system or the cotton count system. The Tex system, which is generally used in manufacturing, is a direct system, arid the number increases with the thread size. The cotton system; and the number decrease with the thread size. Generally it is easier to comparing the Tex numbers when comparing threads with different constructions F example, a core spun thread ha size 100 is equivalent to spun polyester thread in size 70 (T-27); and it is larger than spun polyester in size 100 (T-21) and textured polyester in size 150 (T.-18). If your retailer does not stock threads with a Tex number designation, you can substitute other good quality threads. Long staple polyester, cotton- wrapped polyester, and mercerized cotton threads are suitable for general sewing on most fabrics. For very lightweight fabrics, use fine cotton embroidery thread (60/2) or fine cotton-wrapped polyester. For heavier fabrics, use topstitching thread or buttonhole twist.

The Needle Size Chart from American & Efird, Inc. provides a useful guide for selecting compatible needles and threads. However, it Is important to remember that this is the minimum recommended needle size and that a larger needle may be required for the fabric or application.

CHAPTER - IX TYPES OF STITCHES & SEAM

Page | 117

1.

STITCH CLASSIFICATIONS

How a stitch is formed  The formation of a stitch begins when the needle penetrates the fabric and descends to its lowest point.  The bobbin hook then slides by the needle's scarf, catching the upper thread, and carries it around the bobbin and bobbin thread.  The thread is then pulled up into the fabric, completing the stitch.

Each category of sewing machine produces a specific type of stitch formation depending on the number of needles, looper, and threads which combine to construct the stitch. Each of these configurations is known as a stitch type and they are classified according to their main characterization.

Page | 118

A. STITCH CLASSIFICATIONS Class 100 - Chain stitch One of the simplest stitch types, the chain stitch has one or more needle threads and is formed by Intra looping. This stitch is very Insecure and unravels easily if a stitch is broken or skipped or if the last loop is not fastened securely. This stitch is used for sewing buttons and buttonholes, hemming, basting and pad stitching.

Class 200 - Rand Stitch Generally formed by hand, the hand stitch is made with a needle that is passed from one side of the material to the other as a single line of thread. The most important machine to duplicate this stitch is a pick stitching machine, which is used as a decorative detail on the other edges of jackets.

Class 300 - Lockstitch The most common stitch type, the lockstitch has two or more groups of threads that interlace to form the stitch. One group is called the needle threads and the other the bobbin threads. These stitches do not unravel easily and always require a bobbin. Very versatile, they are used for seaming, hemming, and setting zippers and pockets.

Class 400 - Multi Thread Chain stitch Sometimes called a double-locked stitch, the multithread chain stitch has two or more groups of threads that interlace and interloop with each other. One group is called the needle threads and the other the looper threads. This stitch is actually stronger than the lockstitch; however, if the threads are not properly secured on the finishing end, it will unravel. It is used for seaming and in combination with the over edge stitch on over lock machines. When used for seaming, the needle thread determines the seam strength and the looper threads can be finer.

Class 500 - Over edge Stitch The over edge stitch is formed with one or more groups of threads that interloop to form a thread sheath around the fabric edge. The most common stitches have one or two needle threads and one or two looper threads. Overedge stitches are v elastic and do not in unravel easily. They are for neatening edges trimming woven and low stretch knitted fabrics and decorative edgings. All of the stitches can be used for neatening; however, one and two-thread overedge stitches cannot be used for seaming because the stitch opens up when stressed transversely. And, since the stitches produce a closed seam that cannot be pressed open, it is not always acceptable on better garments. When used for seaming, the needle thread determines the seam strength. This stitch is frequently combined with a multithread. Chain stitch (401) to seam and finish the edges.

Class 600 – Cover stitch The most complex stitch class, the cover stitch is generally formed with three or more groups of threads that cover the raw edges of both surfaces. Very elastic, It is used to create low bulk and decorative seams on underwear and knitted casual garments. Threads should be strong with a soft hand.

SEAM CLASSIFICATION As per the British standard 3870, Part 1 - 1991 seams may classified Into eight types. Class 1 Super imposed Seam French Seam Piped Beam Class 2 Lapped Seam Lap felled Seam Welted Seam Class 3 Bound Seam Class 4 Flat Seam Class 5 Decorative Seam Class 6 Edge neatening Class 7 Addition of other Seams

Class 8 Belt loops General Guide for Seam Allowances Generally the following seam allowances are used in apparel construction, but it must be remembered that this is only a guide and will not be appropriate for every design and fabric.  1/8” to 3/8” Enclosed seams at edges that have separate facings, mach as necklines, collars, cuffs, and armholes, and on intricate curves. The narrowest (1/8”) seam allowances can be used on lightweight fabrics that do not fray, while the widest (3/8”) are used as loosely woven S fabrics and fabrics that ravel easily.  3/8” to 1/2” Sleeves, yokes, waistlines, gores, style lines within the silhouette, center lines, top-stitched seams, cut-out darts, cuff/sleeve seams, band/skirt seams, inseams, and side seams on budget and moderately priced garments.  3/4” to 1”: Vertical seams on better garments, zipper plackets, and darts.
