Properties of Fibres
Comfort :
·
feeling of warmth ,
amount of absorbency stretch , texture of fabric
,
Absorbency
· :
-ability of fabric to absorb + retain moisture who feeling damp ,
a how
quickly the water evaporates
Elasticity
·
:
-ability of fibre to return to its original shape/size right after being stretched not losing shape
·
Resilience :
-ability to retain shape t bulk after being compressed/folded don't crease
Characteristics of
Fabrics
1 .
Wool
·
Advantages
-flexible a elastic , moves with the body
-warm/canfy to wear air trapped in hollow centre of fibre insulates
-very absorbent ,
never feels clammy on skin
Does not wrinkle easily
,
creases hong out
·
Disadvantages
-can't be washed with regular alkaline soap wool is damaged by alkalis
-wool-protein ; danaged by moths/silverfish : needs mothproofing
,
for
-can't stay in sun long ,
tuns yellow
-not strong even weaker when we
,
-not very flame resistant
