Question

a Spinning of fibres increases the. strength yarn How!​

Answer 1

Answer:

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. The fibers are first air dried, then cooled further in a liquid bath

Answer 2

Answer:

hii

Explanation:

The fibres are twisted around each other to give strength to the yarn. Rotor-spun yarns: These are similar to ring-spun yarns and usually made from short staple fibres. They produce a more regular and smoother, though weaker, yarn than ring spinning.
