Question 24

Fibre Properties
Cotton

Answer 24

Good abrasion resistance
Strong due to 70% crystalline regions
Holds 27x weight in water
A cool fibre as it is a good conductor of heat
Breathes easily due to fibre structure
Garments retain their shape due to the inelasticity
Hydrophilic, so it is easily dyed

Question 25

fibre properties
wool

Answer 25

Exceptional drape
Moderate abrasion resistance
Weak, due to the fibre’s highly amorphous structure
Extremely absorbent due to the fibre’s amorphous regions
Excellent elastic recovery
Excellent insulation properties
Poor dimensional stabilitydyed readily due to its highly amorphous structure
Poor shrink resistance

Question 26

fibre properties
rayon

Answer 26

A lustrous fibre – often used for formal wear
Good drapeability
Resists pill
Low to medium strength but the strength reduces by 40–70% when wet
Highly absorbent as it is an amorphous fibre
Poor elasticity due to large percentage of amorphous regions
Good conductor of heat
Poor dimensional stability

Question 27

fibre properties
Polyester

Answer 27

Relatively strong due to highly oriented fibre structure and highly crystalline regions
Poor absorbency, which lowers the comfort
elastic because of the high percentage of crystalline regions
Poor conductor of heat but feels cool against the skin
excellent insulator
Excellent dimensional stability

Question 28

fibre properties
nylon

Answer 28

Drape Good, but can depend on the yarn and fabric construction
Excellent abrasion resistance
Relatively strong due to highly oriented fibre structure and highly crystalline regions
Low absorbency
Relatively elastic due to the high percentage of crystalline regions
Moderate thermal properties
Excellent dimensional stability

Question 29

fibre properties
