Learning Objectives:

Success Criteria:

• Be able to identify a woven fabric • Be able to name properties & characteristics of woven fabrics

A*-A: Be able to create different weave samples with no promoting from the teacher. Be able to speak and write fluently about woven fabrics in the lesson listing all properties and fabric characteristics confidently.

Learning Outcomes: • Be able to tell me how to create at least two different weaves • Have a good sample of each weave • Made detailed revision notes

B: Be able to create different weave samples and display a sound knowledge of their properties and characteristics. C: Be able to create different weave samples in the lesson with at least two properties and characteristics for each.

Weaving

• Spinning is the twisting together of fibres to make a yarn. The more a yarn is twisted the stronger it will be.

• A shuttle takes the yarn from one side to another. • Woven fabrics are not stretchy and tend to fray when cut.

Properties 1. Edges do not fray until cut, as they have a selvedge 1. They can be woven at different densities and have different weights 4. The fabric is at its strongest on the grain line 5. The fabric can stretch on the bias (diagonal) of the fabric.

Types of weave Have a go!

• Plain weave – This is the simplest weave where one weft yarn passes under and over one warp yarn, e.g. poplin, calico. Teacher Demo

Types of weave Have a go!

•Twill weave – Weft yarns pass under or over 2–4 warp yarns. Herringbone is a variation on a twill weave. The fabric has a distinctive diagonal pattern, e.g. denim. Teacher Demo

Types of weave Have a go!

•Satin weave – The weft yarns pass over between 4–7 warp yarns to give smooth and shiny fabrics, e.g. damask. Teacher Demo

Peer Assessment Challenge Pass your work to a friend

• Yellow Hat: What has gone well?

• Black Hat: What has not worked so well?

• Green Hat: How could it be improved? • Write your comments in their books, leaving space

for sticking the woven samples in.

Pile weaves

• Pile weaves can be made by inserting extra warp threads into a plain weave backing. The loops can be cut (e.g. velvet) or left uncut (e.g. terry towel).

• The extra yarns increase the surface area of the fabric which makes it more absorbent. • Pile weave fabrics include velvet, terry towel, corduroy.
