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

Embodiment 1

[0014] Example 1: An aldehyde-free high-fixing effect textile fixing agent, which includes the following mass percentage of raw materials: amino-terminated hyperbranched compound HBP-NH 2 15%, polydimethyldiallylammonium chloride 2%, 3-chloro-2-hydroxypropylmethyldiallylammonium chloride 3%, fatty acid polyethylene glycol ester 6%, the balance is Deionized water.

[0015] Further, the preparation method of the textile fixing agent without aldehyde and high fixing effect includes the following steps:

[0016] 1) Prepare the raw materials according to the mass percentage;

[0017] 2) The amino-terminated hyperbranched compound HBP-NH 2 Place the fatty acid polyethylene glycol ester in an appropriate amount of deionized water and stir until all are dissolved;

[0018] 3) Add polydimethyldiallylammonium chloride and 3-chloro-2-hydroxypropylmethyldiallylammonium chloride to the solution obtained in step 2, and heat the solution to 50°C, well mixed;

[0019] 4) Add the remaining amount of d...

Embodiment 2

[0020] Example 2: An aldehyde-free high-fixing effect textile fixing agent, which includes the following mass percentage of raw materials: amino-terminated hyperbranched compound HBP-NH 2 10%, polydimethyldiallylammonium chloride 1%, 3-chloro-2-hydroxypropylmethyldiallylammonium chloride 2%, fatty acid polyethylene glycol ester 3%, the balance is Deionized water.

[0021] Furthermore, the specific steps of the preparation method of the textile fixing agent without aldehyde and high fixing effect are the same as in Example 1.

Embodiment 3

[0022] Example 3: An aldehyde-free high-fixing effect textile fixing agent, which includes the following mass percentage of raw materials: amino-terminated hyperbranched compound HBP-NH 2 20%, polydimethyldiallylammonium chloride 3%, 3-chloro-2-hydroxypropylmethyldiallylammonium chloride 5%, fatty acid polyethylene glycol ester 8%, the balance is Deionized water.

[0023] Furthermore, the specific steps of the preparation method of the textile fixing agent without aldehyde and high fixing effect are the same as in Example 1.

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 an aldehyde-free high-fixing effect textile fixing agent. Background technique [0002] Fixing agent is one of the important additives indispensable in printing and dyeing industry. For a long time, people have been using the resin fixing agent condensed with dicyandiamide and formaldehyde for textile fixing treatment, and its fixing effect is good, but from the end of the last century, studies have found that this fixing agent contains high free formaldehyde after finishing. After fixing the color of infant clothes, it can cause skin inflammation and even ulcers, which arouses people's attention to the research of aldehyde-free color fixing agents. At present, many countries have strict restrictions on the volatilization of formaldehyde in textiles. [0003] The performance of the fixing agent directly affects the color fastness of the dye on the fabric and determines the ...
