Problems solved by technology

Although the traditional method can obtain dyed products with uniform color and luster, the debugging process takes a long time, and the product quality stability is poor, and it has certain selectivity for dyes
[0004] In addition, after cotton-type fabrics are dyed with reactive dyes, the non-fixed or hydrolyzed dyes washed out during the soaping process will re-stain, resulting in color difference, and even affect the color fastness to washing, color fastness to rubbing and other indicators
Since the printed product is printed with dyes of different colors on the same piece of fabric at the same time, color matching will occur due to back staining during the washing process, which will affect product quality

Embodiment 1

[0018] The anti-reactive dye staining agent is characterized in that: by mass percentage, it includes: 2-10% of alkyl ammonium halide salt, 15-40% of polyvinylpyrrolidone, 10-20% of fatty amine polyoxyethylene ether, alkylphenol and Ethylene oxide condensate is 10-20%, and the rest is water. Alkyl ammonium halide salt is alkyl C8-C16 ammonium halide salt. The halogen of alkyl ammonium halide salt is chlorine or bromine. The structural formula of polyvinylpyrrolidone is:

[0019] The viscosity-average molecular weight of polyvinylpyrrolidone is 8000-40000, and the structural formula of fatty amine polyoxyethylene ether is:

[0020] Wherein a is 10-16, and b is 5-25.

[0021] The formula for modified polyester fiber anti-reactive dye staining agent 1 is composed as follows by mass percentage:

[0022]

[0023] The rest is water.

[0024] Alkyl ammonium halide salts, polyvinylpyrrolidone, aliphatic amine polyoxyethylene ethers, and alkylphenol and ethylene oxide condensa...

Embodiment 2

[0026] For modified polyester fiber anti-reactive dye staining agent 2 formula is composed as follows by mass percentage:

[0027]

[0028] The rest is water.

[0029] Alkyl ammonium halide salts, polyvinylpyrrolidone, aliphatic amine polyoxyethylene ethers, and alkylphenol and ethylene oxide condensates are commercially available conventional industrial products.

Embodiment 3

[0031] For modified polyester fiber anti-reactive dye staining agent 3 formula is composed as follows by mass percentage:

[0032]

[0033] The rest is water.

[0034] Alkyl ammonium halide salts, polyvinylpyrrolidone, aliphatic amine polyoxyethylene ethers, and alkylphenol and ethylene oxide condensates are commercially available conventional industrial products.

[0035] The anti-staining agent provided by the invention is used for dyeing modified polyester fiber / cotton fiber blended fabrics. The modified polyester fibers used in the examples of the present invention are cationic dyeable hollow polyester staple fibers. Polyester fiber is firstly treated with sodium hydroxide and hydrogen peroxide in the same bath, and then dyed with disperse dyes. Finally, it is dyed according to the conventional process of dyeing cotton fibers in the reactive dye laboratory. The color difference between samples before and after dyeing with reactive dyes is measured for the evaluation of...

Abstract

The invention discloses an anti-staining agent for a reactive dye, which is characterized by comprising ammonium salt alkyl halide, polyvinylpyrrolidone, fatty amine polyoxyethylene ether, an alkylphenol and ethylene oxide condensation compound, and water. The anti-staining agent for the reactive dye can be used for resisting staining during a dyeing process of modified polyester fibres and cotton fiber blending fabrics, and also can be used for resisting back staining during the dyeing process of the reactive dye or a soaping process of a printing product. The anti-staining agent for the reactive dye can be conveniently used, and can be directly added in a reactive dye dyeing bath or a soap washing lotion.

Description

technical field [0001] The invention relates to the technical fields of textile auxiliaries and fine chemicals, more specifically, the invention relates to an anti-reactive dye staining agent. Background technique [0002] At present, polyester is an important variety in synthetic fibers and is the trade name of polyester fibers in my country. It is a synthetic high polymer made of terephthalic acid or terephthalic acid and ethylene glycol through esterification or transesterification and polycondensation reactions——polyethylene terephthalate. Fibers made from silk and post-processing. Polyester fiber has the advantages of crispness, non-ironing, mildew resistance and moth resistance, so it is widely used in textile and industrial fields. However, since there are no hydrophilic groups such as carboxyl groups and sulfonic acid groups on the molecular chain of ordinary polyester fibers, it has defects such as poor moisture absorption and air permeability, stuffy clothes, and...
