Problems solved by technology

The wet rubbing fastness and washing fastness of the existing formaldehyde-free color fastness agents are not ideal, and the binding force to dyes is not good, especially when finishing dyes that are difficult to fix, such as bright red and emerald blue, it is easy to hang. The color is not fast, and the existing color fixing agent has the problem of affecting the dyeing shade of reactive dyes, which affects the color of fabric dyeing to a certain extent

Abstract

The invention discloses a formaldehyde-free textile color-fixing agent with a high color-fixing effect. The formaldehyde-free textile color-fixing agent is characterized by being prepared from, by mass, 10%-20% of amino-terminated hyperbranched polymer (HBP-NH2), 1%-3% of poly dimethyl diallyl ammonium chloride, 2%-5% of 3-chloro-2-hydroxypropyl methyldiallyl ammonium chloride, 3%-8% of fatty acid polyglycol ester and the balance deionized water. The color-fixing agent is a textile color-fixing agent which is free of formaldehyde, has the high color-fixing effect and low environmental influence and is smaller in influence on dyeing color light of dye.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a textile color-fixing agent without aldehyde and high color-fixing effect. Background technique [0002] Color fixing agent is one of the indispensable and important auxiliary agents in the printing and dyeing industry. For a long time, people have been using dicyandiamide and formaldehyde-condensed resin color-fixing agent for textile color-fixing treatment. , Infants and young children's clothes will cause skin inflammation and even ulcers after being fixed, which has aroused people's attention to the research of formaldehyde-free color fixing agents. At present, many countries have strict restrictions on the volatilization of formaldehyde in textiles. [0003] The quality of the color fixing agent directly affects the color fastness of the dye on the fabric to wet resistance, and determines the quality of the surface dyeing effect of the fabric. The wet rubbing ...
