Abstract

The invention discloses a terylene deweighting dyeing assistant, and a preparation method and a use thereof. A raw material formula of the terylene deweighting dyeing assistant comprises, by mass, 10-15% of ethylene glycol monobutyl ether, 10-15% of 1,4-butanolide, 10-20% of fatty alcohol polyoxyethylene ether, 10-20% of secondary alkane sulphonate, and the balance water, wherein the molecular formula of the fatty alcohol polyoxyethylene ether is RO-(CH2CH2O)n-H, n is 7-9 or 15-20, and R is a C12-18 alkyl group; and the molecular formula of the secondary alkane sulphonate is R'SO3Na, and R' is a C10-13 alkyl group. The terylene deweighting dyeing assistant guarantees the terylene dyeing effect and the silk like effect and adopts a one-bath technology; and compared with traditional technologies, the technology has the advantages of saving of a lot of time, energy and substances, and great reduction of the pollutant emission.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a polyester weight reduction dyeing auxiliary and its preparation method and application. Background technique [0002] At present, in addition to direct spinning of superfine fibers, polyester imitation silk is mainly processed by 15% and 35% alkali weight reduction to improve the fiber feel and improve the degree of simulation. The principle is that the polyester fiber is hydrolyzed under the action of hot and strong alkali, so that the surface of the fiber is eroded and cracked, the tissue is loose, the fiber is thinner, the weight is reduced, the interweaving resistance of the fabric is reduced, and the rigidity is reduced, so that it is soft like natural silk. Excellent handle, soft luster and good drapability. [0003] Usually polyester pretreatment needs to go through many steps such as degreasing, desizing, alkali weight reduction, opening width, drying, pre-setting pr...
