Q.Assertion (A) : Glass transition temperature plays an important role in producing textured yarns. Reason (R) : The glass transition temperature is the point where crystalline regions of the fibre develop flow or melt. Codes :
Correct answer: (A) is correct, but (R) is incorrect.
Explanation
Glass transition temperature plays an important role in producing textured yarns. Glass transition temperature is the temperature at which a textile material behaves hard as like glass and after which it behaves soft as like rubber. The glass transition temperature is expressed by Tg. The range of glass transition temperature lies between 100oC to 300oC
