Q.Assertion (A) : Textured yarn & permanent pleats are produced by reforming materials at their Tg's. Reason (R) : The glass transition temperature is the point where crystalline regions of the fiber develop flow or melt. Codes :
Correct answer: (A) is correct and (R) is incorrect.
Explanation
Textured yarn and permanent pleats are produced by reforming materials at their Tg's. The glass transition is the point where amorphous region of the fiber change from glassy state to soft state.
