AI Technical Summary

Problems solved by technology

Most of the existing color fixing agents use epichlorohydrin, dicyandiamide and diethylenetriamine as raw materials, while epichlorohydrin is highly toxic and harmful to the human body, and its production requirements are extremely strict during the synthesis process
In addition, the color fixing power of these color fixing agents is not ideal, which restricts the industrialization process of formaldehyde-free color fixing agents

Embodiment 1

[0033] The ratio of each raw material is as follows:

[0034]

[0035]

[0036]The temperature of the polymerization reaction was 70°C; 60 minutes after the start of the polymerization reaction, the remaining monomer solution and initiator solution were added dropwise for 1 hour, and the temperature was lowered to terminate the polymerization reaction after 4 hours after the dropwise addition was completed.

Embodiment 2

[0038] The ratio of each raw material is as follows:

[0039]

[0040] The temperature of the polymerization reaction was 80°C; 30 minutes after the start of the polymerization reaction, the remaining monomer solution and initiator solution were added dropwise for 2.5 hours, and the temperature was lowered to terminate the polymerization reaction after 3 hours after the completion of the dropwise addition.

Embodiment 3

[0042] The ratio of each raw material is as follows:

[0043]

[0044] The temperature of the polymerization reaction was 75°C; 45 minutes after the start of the polymerization reaction, the remaining monomer solution and initiator solution were added dropwise for 105 minutes, and 210 minutes after the completion of the dropwise addition, the temperature was lowered to terminate the polymerization reaction.

Abstract

The invention discloses a polycationic formaldehyde-free color fixing agent and a preparation method thereof. The polycationic formaldehyde-free color fixing agent is prepared from the following raw material components in parts by mass: 90-110 parts of dimethyl diallyl ammonium chloride, 12-18 parts of N-methyldiallylamine, 3-8 parts of acrylic acid, 1.5-2.5 parts of persulfate, 0.75-1.25 parts of hydrosulphite, 5-15 parts of ammonium acetate and the balance of water. According to the polycationic formaldehyde-free color fixing agent disclosed by the invention, dimethyl diallyl ammonium chloride, N-methyldiallylamine and acrylic acid are adopted as monomers, and the monomers are water-soluble and non-toxic and can be in solution polymerization based on a free radical mechanism to ensure that the prepared color fixing agent is environment-friendly and safe and has strong color fixing capacity.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a polycation formaldehyde-free color-fixing agent and a preparation method thereof. Background technique [0002] Fixing agent is an auxiliary agent used to improve the color fastness of dyes on fabrics to wet treatment. It is an indispensable post-dyeing treatment agent when direct dyes and reactive dyes dye cellulose fibers. In recent years, with the development of science and technology, dyeing and finishing technology has also been significantly improved. Due to the expansion of international textile trade and the improvement of people's living standards and environmental protection awareness, textiles are required to be comfortable, clean and safe. [0003] Since Germany took the lead in launching the "Blue Angel" plan in the 1970s, some developed countries in the world (such as Japan, the United States, etc.) have successively passed and implemented relevant law...
