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 dyeing auxiliary agent for weight reduction and a preparation method and application thereof. Background technique [0002] At present, in addition to the direct spinning of superfine fibers, the artificial silk processing of polyester mainly uses 15% and 35% alkali reduction processing to improve the fiber feel and improve the degree of simulation. The principle is that polyester fiber is hydrolyzed under the action of hot and strong alkali, so that the surface of the fiber is eroded and uneven and cracked. hand, soft luster and good drape properties. [0003] Usually polyester pretreatment needs to go through many steps such as degreasing, desizing, alkali reduction, opening, drying, and presetting. Among them, oil removal and alkali reduction consume a lot of energy, water, time, and produce a lot of pollutants. Simplifying the complicated steps of polyester p...
