Learning Objectives:<br />

• Be able to identify a woven<br />

fabric<br />

• Be able to name properties &<br />

characteristics of woven<br />

fabrics<br />

Learning Outcomes:<br />

• Be able to tell me how to<br />

create at least two different<br />

weaves<br />

• Have a good sample of each<br />

weave<br />

• Made detailed revision notes<br />

Success Criteria:<br />

A*-A: Be able to create<br />

different weave samples with<br />

no promoting from the<br />

teacher. Be able to speak and<br />

write fluently about woven<br />

fabrics in the lesson listing<br />

all properties and fabric<br />

characteristics confidently.<br />

B: Be able to create<br />

different weave samples and<br />

display a sound knowledge of<br />

their properties and<br />

characteristics.<br />

C: Be able to create<br />

different weave samples in<br />

the lesson with at least two<br />

properties and<br />

characteristics for each.


• Spinning is the<br />

twisting together of<br />

fibres to make a<br />

yarn. The more a<br />

yarn is twisted the<br />

stronger it will be.<br />

Weaving<br />

• A shuttle takes the<br />

yarn from one side to<br />

another.<br />

• <strong>Woven</strong> fabrics are not<br />

stretchy and tend to<br />

fray when cut.


Properties<br />

1. Edges do not fray<br />

until cut, as they<br />

have a selvedge<br />

1. They can be woven<br />

at different<br />

densities and have<br />

different weights<br />

4. The fabric is at its strongest on the grain<br />

line<br />

5. The fabric can stretch on the bias (diagonal)<br />

of the fabric.

yarn is called<br />

the WEFT<br />

yarn ‘weft<br />

The vertical<br />

yarn is called<br />

the WARP<br />

yarn ‘warp<br />

yarn is also<br />

called the<br />

At the edge of a woven<br />

piece of fabric the<br />

warp yarns wrap<br />

around the weft yarns,<br />

this is called the<br />

• Plain weave –<br />

Types of weave<br />

Have a go!<br />

This is the simplest<br />

weave where one<br />

weft yarn passes<br />

under and over one<br />

warp yarn, e.g.<br />

poplin, calico.<br />

Teacher Demo


Types of weave<br />

Have a go!<br />

•Twill weave – Weft<br />

yarns pass under or over<br />

2–4 warp yarns.<br />

Herringbone is a variation<br />

on a twill weave. The<br />

fabric has a distinctive<br />

diagonal pattern, e.g.<br />

denim.<br />

Teacher Demo


•Satin weave –<br />

Types of weave<br />

Have a go!<br />

The weft yarns pass<br />

over between 4–7<br />

warp yarns to give<br />

smooth and shiny<br />

fabrics, e.g. damask.<br />

Peer Assessment Challenge<br />

Pass your work to a friend<br />

• Yellow Hat: What has gone well?<br />

• Black Hat: What has not worked so well?<br />

• Green Hat: How could it be improved?<br />

• Write your comments in their books, leaving space<br />

for sticking the woven samples in.


Pile weaves<br />

• Pile weaves can be made by<br />

inserting extra warp threads<br />

into a plain weave backing.<br />

The loops can be cut (e.g.<br />

velvet) or left uncut (e.g.<br />

terry towel).<br />

• The extra yarns increase the<br />

surface area of the fabric<br />

which makes it more<br />

absorbent.<br />

• Pile weave fabrics include<br />

velvet, terry towel, corduroy.
