IMPROVER OF FASTNESS TO HEAT AND LIGHT FOR FIBER AND METHOD FOR IMPROVING FASTNESS TO HEAT AND LIGHT OF FIBER

摘要

PURPOSE:To improve fastness to heat and light of a fiber useful for sheet for car, interior, short wear, etc., by adding specific three kind of compounds into a dyeing bath and absorbing these compounds into a fiber while dyeing the fiber. CONSTITUTION:A improver of fastness to heat and light of fiber, consisting of a compound expressed by formula I (X is H or halogen; R1 is H, 1-6C alkyl or alkoxy; m is 1-4; n is 1-30), compound expressed by formula II (X is 1-4C alkyl; R2 is H or methyl) and compound expressed by formula III (Y is 1-10C alkylene or formula TV; R3 is 1-5C alkyl or alkoxy) is added into a dyeing bath at total amount of =10% o.w.f. to absorb the objective improver into the fiber while dyeing the fiber.
