AI Technical Summary

Problems solved by technology

The dyeing of nylon by acid dyes is mainly due to the ionic bonding between the dye anion and the ionized terminal amino group of nylon acid. The initial color yield of nylon fabrics is much higher than that of wool. The dyeing rate of acid dyes on nylon Fast, prone to uneven dyeing, a large bath ratio is required during dyeing, generally the bath ratio should reach more than 1:20, the dyeing consumes a lot of water and energy, resulting in a large amount of wastewater discharge and serious pollution

Abstract

The invention discloses an adjuvant composition suitable for dyeing of an acid dye with small bath ratio, and aims to overcome problems in dyeing of on polyamide fabric by an acid dye, such as large water consumption and high energy consumption. The adjuvant composition provided by the invention is prepared by mixing a levelling agent O, a dispersant MF and an emulsifier in the weight ratio of 1: 0.5-0.8: 0.2 -0.7. The invention can greatly reduce dyeing bath ratio of the acid dye, thus greatly reducing dyeing water and sewage discharge, and significantly improving quality and brightness of a product. At the same time, due to decrease of the bath ratio, steam consumption for maintaining a same dyeing temperature is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an auxiliary composition suitable for dyeing with small liquor ratio acid dyes and its application. Background technique [0002] In the past ten years, the problems of energy shortage and environmental pollution have become increasingly prominent. At the same time, the competition in the international textile market has become more intense, requiring high processing efficiency and low processing costs. High-end ecological stockings are the main development direction of stockings. High-end ecological stockings require bright color, soft touch, excellent fastness, and ecological comfort. The dyeing and finishing of high-grade ecological stockings is a processing process with the main medium of water and chemical additives. How to reduce water consumption, reduce the discharge of toxic and harmful chemicals, and reduce the generation of waste is the key to the s...
