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

[0036] The ratio of each raw material is as follows:

[0037]

[0038] Table note: MCP-1 heavy metal ion scavenger is MCP produced by Guangzhou Nasen Chemical Co., Ltd. TM One of the models of series products, the following embodiments are all the same.

[0039] 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

[0041] The ratio of each raw material is as follows:

[0042]

[0043]

[0044] 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

[0046] The ratio of each raw material is as follows:

[0047]

[0048] 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 formaldehyde-free color-fixing agent and a preparation method of the color-fixing agent. The formaldehyde-free color-fixing agent comprises the following raw materials in parts by weight: 90-110 parts of dimethyl diallyl ammonium chloride, 12-20 parts of acrylamide, 6-10 parts of 2-hydroxyethyl acrylate, 1.6-2.3 parts of peroxysulphate, 0.45-0.85 part of hydrosulphite, 0.10-0.18 parts of a heavy metal ion capture agent, 0.8-3 parts of nano silicon carbide, 0.2-1 part of a siloxane coupling agent and the balance of water. A siloxane coupling agent is used for carrying out surface modification on the nano silicon carbide to obtain the modified nano disilicon; the abrasion resistance and the mechanical property of the color-fixing agent can be remarkably improved; dimethyl diallyl ammonium chloride is used as a main monomer and is used for carrying out solution copolymerization together with water-soluble acrylamide and 2-hydroxyethyl acrylate to prepare a cationic quaternary ammonium salt polymer, so that the prepared color-fixing agent is environmentally friendly, safe and strong in color-fixing effect.

Description

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