Q.Assertion (A) : Fibres with amorphous arrangement of polymers have a better water absorption and dye uptake. Reason (R) : In amorphous arrangement, polymers are arranged in a random manner making the fiber more absorbent.
Correct answer: Both (A) and (R) are correct
Explanation
Amorphous region of fiber is the region in which polymers are arranged in random manner making more space between the fibers which make it more absorbent. Fibers with amorphous arrangement of polymers have more affinity to water and dye.
