Assertion: Draw texturing of isotactic polypropylene (POY) at a relatively high speed is possible despite high crystallinity of the feeder yarn.
Reason: Isotactic polypropylene (POY) has majorly smectic mesomorphic phase.
A
Both [a] and [r] are true and [r] is the correct reason for [a]
B
Both [a] and [r] are true but [r] is not the correct reason for [a]
