Problems solved by technology

However, epichlorohydrin is highly toxic. During the preparation process, the volatile gas is very harmful to the human body, and its production requirements are extremely strict during the synthesis process.
In addition, the color-fixing effect of these color-fixing agents is not ideal, which restricts the industrialization process of formaldehyde-free color-fixing agents

Embodiment 1

[0034] The ratio of each raw material is as follows:

[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 color fixing agent and a preparation method thereof. The color fixing agent is prepared from the following raw materials in parts by mass: 90-110 parts of dimethyl diallyl ammonium chloride, 20-30 parts of triallylamine, 8-16 parts of allyl alcohol, 2-2.6 parts of persulfate, 0.95-1.35 parts of hydrosulphite, 0.16-0.2 part of dithiocarbamate, 1.2-4.5 parts of nano-silicon dioxide, 0.15-0.8 part of a silane coupling agent and the balance being water. The silane coupling agent is adopted for modifying the surface of the nano-silicon dioxide, and the obtained modified nano-silicon dioxide is capable of obviously improving the wear resistance and the mechanical properties of the color fixing agent; the dimethyl diallyl ammonium chloride is selected as a main monomer and subjected to solution copolymerization with the water-soluble triallylamine and the allyl alcohol to obtain a cationic quaternary ammonium salt polymer; as a result, the obtained color fixing agent is environmentally-friendly, safe, and high in color fixation effect.

Description

technical field [0001] The invention relates to the technical field of knitted textiles, in particular to a 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 laws and regulations to restrict va...
