Problems solved by technology

[0004] There are many kinds of color-fixing agents on the market, but many color-fixing agents contain formaldehyde, which are not environmentally friendly, and the color-fixing effect is not ideal. Some of them have serious discoloration
[0005] Foreign products such as: Switzerland Ciba (Ciba Co.) company's color-fixing agent ECO, German Bayer (Bayer) company's color-fixing agent WRT-T, Shanghai Daxiang Company (Japan) color-fixing agent DX 300, color-fixing agent The effect of DX 401 is acceptable, but the product price is high

Abstract

The invention relates to a cationic high-molecular low-temperature self-crosslinking formaldehyde-free color fixing agent and a preparation method. The color fixing agent is prepared from the following raw materials: dimethyl diallyl ammonium chloride containing 350 to 420kg of cationic monomer, water-soluble monomer comprising 0 to 20kg of acrylamide and 0 to 20kg of allyl amine, 10 to 20kg of low-temperature self-crosslinking reactive monomer, 10 to 20kg of low-temperature self-crosslinking accelerant, 1.0 to 2.0kg of evocating agent (ammonium persulfate) and 380 to 450kg of deionized water. The cationic high-molecular low-temperature self-crosslinking formaldehyde-free color fixing agent has the advantages that the color fixing agent can achieve ideal color-fixing effect and increase dye utilization rate, dyeing fastness and product quality. The preparation method has simple production process flow and low cost, and adopts a closed production process and special production equipment, thereby converting all input raw materials into products; and 'three wastes' (waste gas, waste water and waste residue) do not generated during the entire production course and the method is suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of color fixing agents, and mainly relates to a cationic polymer low-temperature self-crosslinking formaldehyde-free color fixing agent and a preparation method thereof. Background technique [0002] The main reason for the poor wet rubbing fastness of dyed textiles is the floating color transfer of water-soluble dyes and the mechanical friction transfer of colored fiber particles. The main causes of poor are floating and unpigmented hydrolyzed dyes. [0003] The principle of color fixation is to use the cationic groups in the organic ammonium salt and the anionic groups in the dye to form an insoluble lake, so that the combined dye is insoluble in water or the dye is difficult to dissolve in water, because ions are formed between them Bond or van der Waals attraction, and there are groups in the fixing agent molecule that can react with dyes and fibers, so the utilization rate of dyes can be improved after treatment...
