Q.Assertion A : When disperse dyes are applied to polyesters at low temperatures, carriers are required to bring about penetration of the dye molecules into the fiber. Reason R : High pressure and high temperature eliminates the need for carriers.
Correct answer: Both A and R are true and R is the correct explanation of A
Explanation
When disperse dyes are applied to polyesters at low temperatures, carriers are required to bring about penetration of the dye molecules into the fiber. But high pressure and high temperature eliminates the need for carriers
