Question 7

Leather properties and uses

Answer 7

• Long lasting, sustainable

- Used in shoes and car seats

Question 8

What are synthetic fibres

Answer 8

Fibres which are made from polymers ( long chain molecules) which come from coal and oil ( non- renewable fossil fuels)

Question 9

Properties of synthetic fibres

Answer 9

• Resistant to biological damage (moths and moulds)
• not very absorbent so hard to dye
• can be changed by heating to form different shapes and textures
• less sustainable than natural fibres

Question 10

Examples of synthetic fibres

Answer 10

Elastane
Polyester
Linen
Polyamide

Question 11

Properties and uses of elastane

Answer 11

• Extremely elastic, soft, lightweight, keeps shape well
• Not absorbent, high flammability
• Used in LYCRA ,sportswear, underwear,

Question 12

Properties and uses of polyester

Question 14

What are fabrics made of

Answer 14

Fibres which are spun into yarn

Question 15

What are yarns

Answer 15

Threads that are woven or knitted to make fabrics

Question 16

What are yarns made of

Answer 16

fibres which can come in short lengths (staple fibres) or longer lengths (filaments)

Question 17

How can filaments and staple fibres be spun

Answer 17

Filaments can be spun or used how they are and staple fibres are spun to produce yarns

Question 18

how are woven fabrics made

Answer 18

by interlacing two sets of yarn (crossing alternately over and under)

Question 19

how are knitted fabrics made

Answer 19

by interlocking one or more yarns together using loops, these loops trap air, so they insulate. They stretch more than woven fabrics

Question 20

how are non- woven fabrics made

Answer 20

layers of fibres held together by bonding or felting, don’t fray, can be cut in any direction, meaning less waste when laying out patterns, however not strong and do not stretch
