Question

How does spinning of fibers incress the strength of yarn ​

Answer 1

Answer:

The polymer is in a "gel" state, only partially liquid, which keeps the polymer chains somewhat bound together. These bonds produce strong inter-chain forces in the fiber, which increase its tensile strength. The polymer chains within the fibers also have a large degree of orientation, which increases strength.

Answer 2

Answer:

Actually these bonds produce strong inter-chain forces in the fiber,which increases its tensile strength.The polymer chains within the fibres also have a large degree of orientation which increases strength.The fibres are the first air dried,then cooled further in a liquid.

Factor that affect yarn strength are:-

Staple length

Fibre Fineness

Fibre strenth

twist
