COST AND QUALITY QUALITY: Quality is defined as “Totality of characteristics of an entity (product, service etc.) that bears on its ability to satisfy stated and implied needs.” QUALITY CONTROL: Is an effective system for interchanging the quality maintenance and quality improvement efforts of various groups in an organization so as to enable production at the most economical levels which allow full satisfaction for the consumers. TOTAL QUALITY MANGEMENT (T.Q.M.): Is described as an all- inclusive fully integrated productivity technique. It helps to create new markets, expand existing markets and recapture lost markets by utilizing the optimum capability of man, machine, material, method and produces high and uniform quality of products with reduced costs. Total quality control starts from market i.e. from purchasing material and machine and ends in the market i.e. selling the finished products in the market including after-sale service. It includes market analysis, product development, production planning, statistical quality control, preventive maintenance, wastage control, inventory control, cost reduction and after sales service et. The ultimate goal of T.Q.M. is to increases the quality/cost ration and continuous improvement. It may be done by increasing the quality with same cost, decreasing the cost with same quality and increasing quality and decreasing coast at the same time. The above graph shown that there is an optimum quality of a product. Above this optimum, the increased the cost, there will be no increase of quality. But below the optimum, lower the quality lesser the cost. The basic quality problem is to set correct balance between the cost and quality i.e. to find out a suitable quality/cost ration for the product which will satisfy the consumer both for cost and quality.

FABRIC INSPECTION PROCEDURE - 4 POINT SYSTEM OBJECTIVE The aim of fabric inspection is to check the quality, quantity and packing by visual, measurement a color check confirming with the specification and general appearance of the approval sample given by buyer. INSPECTION PROCEDURE: • Receive approved color and quality swatches. • Check lot size and label against the submitted packing list. • Randomly draw 10% of the lot. • Delivery of less than 1000 yds – 100% inspection • Delivery of 1000 yds to 10000 yds to inspect at least* 1000 yds. • Shipment of more than 10000 yds inspects 10% of the lot. PENALTY POINT EVALUATION: Fabric to of graded will be examined from a distance of approximately three feet while runner-Up cover the perch of a fabric inspection machine. The inspector will run the fabric at a speed compatible with his ability to distinguish. POINT CALCULATION INDIVIDUAL ROLL Penalty points X 36X 100 Total yrds Inspected x Width of cloth in inch 11

= Points per 100 Sq. Yard AVERAGE POINTS PER SHIPMENT Total Points per 100 Sq. yd of all rolls Inspected Total number of rolls Inspected = Average points per 100 Sq. yard PENALTY POINTS IN FOUR POINT SYSTEM The position of the defect in the fabric in either length or width ROLLS SELECTION PROCEDURES • These rolls shall be selected for inspection on a totally random basis. • The knit dyeing unit is required to present the inspector with a shipment packing list

when eighty (80%) percent of the rolls are packed from which the rolls to be inspected will be chosen. • Once the inspector has selected the rolls for inspection, no adjustment may be made

to the number of rolls to be inspected or to the rolls selected for inspection. • At no time during the inspection may any yardage be removed from any roll other than

for recording and measuring shade tolerances. • All rolls inspected will be graded and assigned penalty points.

ACCEPTABLE PENALTY POINTS: If no specifies standard provided for knit fabric, the average point value per shipment not exceeds 40 points per 100 linear yards. Individual rolls exceeding 40 points shall be rejected. DEFECTS CONDITIONS •No more than 4 points will be penalized within one yd. •Severe defects are assigned max 4 points for each yd. •Any hole and any running defect will be penalized 4 points •Whole roll having running defect or continuous defects in more than 10 yds will be

considered reject.

SPLICE ALLOWANCE • It will not be allowed more than one splice. 12

• No part of a spliced roll can be shorter than 40 yds except specified by customer.

ROLL LENGTH • Roll found to deviate more than 2% from the roll ticket yds shall be rejected. • The entire shipment shall be rejected if the total measured yds in the sample t audi deviates 1 % or more from the ticket yds. HAND FEEL The hand feel will be checked between roll with a reference sample. If there is a noticeable difference, the roll will be classified as second quality. SHADE HATCHING Roll to roll with head to end, side to side, side center side will be checked during visual quality inspection for preliminary. Final checking will be taken in the light box against gray scale rating. Under light source D-65. COLOR SHADING 1) Side to Side 2) Side center Side 3) End to End 4) Lot to Lot 1) Against approval sample

RATING 4 – 5 or 5 (Accepted) 4 – 5 or 5 (Accepted) 4 – 5 or 5 (Accepted) 4 or 4 – 5 or 5 (Accepted) 4 or 4 – 5 or 5 (Accepted)

ACCEPTABLE POINT COUNT LEVEL Various types of textiles are divided into the following five groups. Individual rolls exceeding the specified point count level shall be graded as second quality. A shipment shall fail the inspection if the shipment penalty count points exceed the specified point count level REJECTION RATE: If total rejected inspection yardage is over 10% of total inspected yardage, then overall result is concluded as "Rejected"

RUNNING DEFECTS: •

Any defect found to repeat and/or run in a continuous manner will constitute a running defect. All running defects must be assigned four points to every yard in the roil when the running defect occurs. 13



Any roll having a running or repeating defect through more than three continuous yards shall be rejected regardless of point occurs.

FULL WIDTH DEFECTS: • No roll that contains more than four full width defects per one hundred linear yards

shall be accepted as first quality.

• Any roll found to contain defects, in any increment of one hundred yards, with and

average of more than one major defect per ten linear yards will be rejected.

• No roll shall be accepted that contains a major defect in the first or last three yards of

the rolls. A major defect is considered to be any three or four point defect

• No roll shall be accepted as first quality that exhibits a noticeable of loose or tightness

along either or both selvedges or ripples, puckers, folds or creases in the body of the fabric that would prevent the fabric form lying flat when being spread in a conventional manner.

FABRIC WIDTH: • Fabric width will be checked a minimum of three times during the inspection of a roll,

beginning, middle and end. The roll width will be checked more often if the fabric is close to the specified minimum width of if the fabric width is uneven. • Rolls `paving a measurement of less than the specified width will not be accepted. • For knit fabric, rolls having a measurement of 1" wider than the specified diameter will not be accepted.

SAMPLING TECHNIQUE The purpose of sampling is to draw correct conclusion about the population from the' sample, now if the sampling is not proper, we may be misguided for taking action onthe basis of wrong sampling. Again a inspector can not check all the items produced in a factory in the whole day, it will cause more man power, more cost, more time and more labor. If proper, sampling technique is used to draw sample, it will not only reduce these fa cto rs, w i ll al so red u ce the mo n o ton o u sne ss o f th e in sp e cto r . On e o f th e m o s t important thing of sampling technique is the business of the inspector. Inspector can not take sample as per his wish, he must follow the random number table and probability each item to be drawn is equal. There are various types of sampling of which, sample random sampling, stratified random sampling, systematic sampling are commonly used. SIMPLE RANDOM SAMPLING :- Is a method of selection n units out of N, such that every one of the Cn samples has an equal chance of being chosen. It is the simplest type of probability sampling and is the basis of most of the other sampling methods. In practice a single random sample is drawn unit by unit. I he units of the population are numbered I to N.A series of random numbers between I and N are drawn with the help of random number table or computer which produces such table.

USE A RANDOM NUMBER TO SELECT A SAMPLE:- the RAND Corporation of USA has published a random number table in 1955 in the name " A million random digits with 100000 normal Deviates" To select a sample with this table, let us consider we have 750 items numbered from 1 to 750 on each item and we want to draw a sample of size 5. For these purpose we need to select three digits number 001 to 750. First it is necessary to determine the starting point of the table. The random number table contains 50 rows and 50 columns of digits. We are starting from 8 t h row 39 t h column from there the first number is 471, 098, 443, 335 1 015 it we arrange 26

them in order then 015, 098, 335, 443, 471. Again we want to select sample of seize 10 from a population 500, for this we have to select three digit number i.e. from 001 to 500. Let us start from row 30 arid column 11 then our first number will be 732 but it is not in our serial no so we will exclude it, by going down we will have 752, 640, we will also exclude these. Next 268, 454, 013, 201, 017, 194, 361, 452, 419, 312 excluding all the numbers which are out of serial. Arranging the numbers in order 013, 017, 194, 201, 268, 312, 361, 419, 452, 454 these are the sample numbers which we want to select randomly.

PRE-SHIPMENT SURVEY BY ACCEPTANCE SAMPLING ACCEPTANCE SAMPLING:- Is the art or science that deals with procedures in which decision to accept or reject lots or process are based on- the examination of samples. 100 percent inspection is generally not justified because of time and cost as well as for t h e s h o r t a g e o f t r a i n e d ma n p o w e r . G o o d sa m p l i n g i n sp e c t i o n , w h e r e t h e i t e m s inspected are examined carefully may even provide. Better assurance -of product quality than 100 percent inspection with carelessness. The purpose of acceptance sampling is to specify course of action not to control lot quality. Acceptance sampling plan merely accepts c, , rejects lots. Generally we like to ensure that lots of manufactured goods do not contain an excessively large portion of defective items. This is achieved mainly through the technique of sampling inspection. Acceptance sampling has indirect effect on improvement of quality through its encouragement by high rate of acceptance of good quality and through discouragement of bad quality by high rate of rejection. It also reduces the risk of rejection of good lots and accepting of . bad lots on the basis of sample. TERMINOLOGY OF ACCEPTANCE SAMPLING LOTS SIZE :- Is the number of units in the lot and is denoted by "N" SAMPLE SIZE :- The number of units in the sample and is denoted by "n" LOT INSPECTION :- A specific quantity of similar material, or a collection of similar units, offered for inspection and acceptance at one time. SAMPLING INSPECTION PLAN:- A specific plan which states (a) the sample size (b) The criteria for accepting, rejecting, or taking another sample, to be used in c inspe ting a lot. ACCEPTANCE NUMBER :- The large number of defectives (or defects) in the sample or samples under consideration that will permit the acceptance of the inspection lot is called acceptance number, and is denoted by "Ac". REJECTION NUMBER :- The smallest number of defectives (or defects) in the sample or samples under consideration that will require the rejection of inspection lot is called rejection number, and is denoted by "Re". PRODUCER'S RISK :- The probability of rejecting a lot under the sampling inspection plan when the fraction defective in the lot is actually with in specified limit is called producer's risk and is denoted by "Pp" 27

CONSUMER'S RISK :- the probability of accepting a lot with higher fraction defective than the specified limit under the sampling inspection plan is called consumer's risk. And is denoted by "Pc". SINGLE SAMAPLING INSPECTION PLAN:- Is the sampling inspection plan in which a decision to accept or to reject a lot is reached after the inspection of a single sample. PROCESS AVERAGE QUALITY:- Expected quality of products form a given process, usually estimated from first sample inspection results of past lots. ACCEPTABLE QUALITY LEVEL :- The maximum percent defective that, for purpose of sampling inspection, can be considered satisfactory as a process average is called acceptable quality level anti is denoted by AQL. PROBABILITY OF ACCEPTANCE :- Probability that a lot or will be accepted is called probability of acceptance and is denoted by "Pa" OPERATING CHARECTERSTIC CURVE OR O.C CURVE :- A curve showing the relation between the probability of acceptance, either lot quality or . process quality, which ever is applicable is called O.C CURVE. The stealer the OC CURVE, the greater is the protector to the consumer against accepting a bad lot. AVERAGE SAMPLE NUMBER:- The expected value of the sample size required for Coming to a decision, i.e, for acceptance or rejection of a lot, under the sampling inspection plan is called average sample number and is denoted by ASN. The curve obtained by plotting ASN against "P" is called ASN curve. Lower the ASN curve better is the sampling inspection plan. MAJOR DEFECT.- A major defect is a defect that is likely to result in failure, or to reduce materially the Liability of the unit of product for its intended purpose. MINOR DEFECT:- A minor defect is a defect that is not likely to reduce m a t e r i a l l y t h e u s a b i l i t y o f t h e u n i t o f p r o d u c t for its intended purpose, or a departure from established standards having little bearing on the effective use or operation of the unit. Minor defects may be classified into two categories, more important minor defects may be designated as Minor "A" and less important ones, Minor "B" C R ITOR IA FOR S H IFTIN G TO TIGH TE N E D INSPECTICN:- When normal inspection is on effect, tightened inspection to be instituted when 2 out of 5 consecutive lots or batches have been rejected on original inspection. C R I T O R I A F O R S H I F T I N G TO N O R M A L I N S P E C T I O N F R O M TIGHTENED INSPECTICN:- When tightened inspection is in effect, normal inspection shall be

instituted when 5 consecutive lots or batches have been considered acceptable on original inspection, criteria for shifter to reduced inspection:- When normal inspection is on effect, reduced inspection maybe institute when, (a)

The preceding 10 lots or batches have been on normal inspection and has been accepted on original inspection.

28

(b) (c)

(d)

The total number of defects in the samples from the preceding 10 lots or batches are equal to or less than the desired level. Production is at a steady rate. Reduced inspection is considered desirable by the responsible authority.

CRITERIA FOR SHIFTING TO NORMAL INSPECTION FROM REDUCED INSPECTION :- When reduced inspection is on effect, normal inspection must be reinstated whenever a lot or batch is rejected or production becomes in e-regular .or delayed or other conditions warrant that normal inspection shall be instituted.

AQL SYSTEM FOR ACCEPTANCE SAMPLING (US-MIL-STD 105E) The AQL (Acceptable Quality Level) concept was first devised in connection with the development of statistical acceptance sampling for the Ordinance department of the U.S. Army in 1942, modified as MIL-STD- 105A in 1950, MIL-STD-105B in 1958, MILSTD-105C in 1961, MIL-STD-105D in 1963. American, British, Canadian military agencies has accepted it as common standard of acceptance sampling, that is why it is also called ABC, standard. Later on this standard has accepted by most of American and European organizations. Latest development of these series is MIL-STD-105E in 10 may 1989.

HOW TO USE (US-MIL-STD-105E) For the use of 'US-MIL-STD-105E we have to choose level of AQL first, next step is to find out sample size code letter according to lot size from the sample size code letter table, then: with" the help of sample size code letter and AQL level, to find out acceptance number and rejection number form the normal or tighten, single or double sampling table of US-MILSTD-105E.

CONTROL OF NON CONFORMING PRODUCTS Section 6 9.1

PURPOSE:

To prevent the dispatch of nonconforming products to the customer. 9 .2 S C OP E : This section applies to the products which do not conform the require quality. 9.3

ACTIVITIES:

9.3.1 Non-conforming goods are identified during the checking of receiving section. Process inspection or final inspection.

• When a major nor conformance is discovered i.e. (one that requires a managerial"{., 29

executive decision regarding it's disposition) it is so identified and segregated," subject to the appropriate management decision, the defective goods are reworked, accepted on concession, re-graded or rejected. • W`here appropriate, the customer is consulted concerning any concession.

CONCLUSION Quality has always been a primary requirement and consider to be the life of a garment. There is no denying the fact that XYZ Ltd. had 4 Quality Control System in the production process since its birth but there might been following have been differences in those applications in her five factories. Compiling this quality manual is a humble effort to put almost all necessary details of Quality Control System to ensure that all our factories have a written Manual/ Guideline in black and white to follow. In the beginning we will not concentrate on the statistical Quality Control System. We will follow this after a while when we have enough and required manpower to exercise that. Any positive inclusion in this manual which will help the factories in improving quality is always welcome; but has to done with prior approval from the Managing Director, XYZ Ltd. We all need to educate and train our work force in line with this Quality Manual to try ands streamline our quality system. Our united and sincere effort only can help to improve in the sector of quality.
