Q

What qualities do fabrics with crystalline structures have?

A

Polymers are packed closely and in a parallel arrangement.

  • Good strength
  • High durability
  • Low absorbency
  • Not easily dyed
  • Less elasticity
  • Poor abrasion resistance

A

The direction of the twist of a yarn?

18
Q

What are the properties of a low spun yarn?

A
  • soft, hairy, low lustre, for resiliency.
  • weak, poor abrasion resistance.
  • good insulation, good absorbency, poor elasticity.
  • slow drying.
19
Q

What are the properties of a high spun yarn?

A
  • firm, smooth, good lustre, good resiliency.
  • strong, good abrasion resistance.
  • poor insulation, poor absorbency, good elasticity.
