Embodiment 1

[0028] A kind of efficient and stable environment-friendly dyeing auxiliaries, its raw material comprises 30 parts by weight of water, 40 parts of polyethylene glycols, 5 parts of methacrylic acid acetoacetate ethylene glycol diesters, 5 parts of stabilizers, 5 parts of solubilizers, 2 parts of emulsifier, 10 parts of chitosan, 3 parts of co-solvent, the water is deionized water, which contains less soluble ions and will not react with the components in the dyeing auxiliaries.

[0029] The stabilizer is one of citric acid or acetic acid, and using citric acid or acetic acid as the stabilizer to adjust the pH of the dyeing auxiliaries not only has low raw material prices, but also does not irritate the human body;

[0030] The emulsifier is dodecyltrimethylammonium chloride or dodecyltrimethylammonium bromide, which has good emulsification and dispersibility, so that an emulsion with extremely small particle size and excellent permeability can be produced. Therefore, it is very...

Embodiment 2

[0040] A kind of high-efficiency and stable environment-friendly dyeing auxiliaries, its raw material comprises water 35 parts by weight, polyethylene glycol 45 parts, methacrylic acid acetoacetate ethylene glycol diester 7 parts, stabilizer 6 parts, solubilizer 7 parts, 3 parts of emulsifier, 13 parts of chitosan, 4 parts of co-solvent

[0041] The stabilizer is one of citric acid or acetic acid, and using citric acid or acetic acid as the stabilizer to adjust the pH of the dyeing auxiliaries not only has low raw material prices, but also does not irritate the human body;

[0042] The emulsifier is dodecyltrimethylammonium chloride or dodecyltrimethylammonium bromide, which has good emulsification and dispersibility, so that an emulsion with extremely small particle size and excellent permeability can be produced. Therefore, it is very easy to penetrate into the interior of the fabric during application, so that it has good color absorption performance and makes the dyed fabr...

Embodiment 3

[0052]A kind of efficient and stable environment-friendly dyeing auxiliaries, its raw material comprises 40 parts by weight of water, 50 parts of polyethylene glycols, 8 parts of methacrylic acid acetoacetate ethylene glycol diesters, 7 parts of stabilizers, 8 parts of solubilizers, 4 parts of emulsifier, 15 parts of chitosan, 5 parts of co-solvent.

[0053] The stabilizer is one of citric acid or acetic acid, and using citric acid or acetic acid as the stabilizer to adjust the pH of the dyeing auxiliaries not only has low raw material prices, but also does not irritate the human body;

[0054] The emulsifier is dodecyltrimethylammonium chloride or dodecyltrimethylammonium bromide, which has good emulsification and dispersibility, so that an emulsion with extremely small particle size and excellent permeability can be produced. Therefore, it is very easy to penetrate into the interior of the fabric during application, so that it has good color absorption performance and makes ...

Abstract

The invention relates to the technical field of dyeing auxiliaries, in particular to an efficient and stable environment-friendly dyeing auxiliary, and aims to solve the problem that the dyeing auxiliary is poor in environment-friendly performance and stability in the prior art. According to the scheme, the efficient and stable environment-friendly dyeing auxiliary is prepared from the following raw materials in parts by weight of 30-40 parts of water, 40-50 parts of polyethylene glycol, 5-8 parts of ethylene glycol acetoacetate methacrylate, 5-7 parts of a stabilizer, 5-8 parts of a solubilizer, 2-4 parts of an emulsifier, 10-15 parts of chitosan and 3-5 parts of a cosolvent. According to the invention, components harmful to the environment in an existing dyeing agent are replaced, the cost of raw materials is reduced, the stability of the dyeing auxiliary is greatly improved, it is guaranteed that pigment does not fade for a long time after dyeing, and application and popularization are easy.

Description

technical field [0001] The invention relates to the field of dyeing auxiliaries, in particular to an efficient and stable environment-friendly dyeing auxiliaries. Background technique [0002] The process of fabric preparation involves printing and dyeing processes, and when fabrics with poor color fastness encounter water, sweat, sunlight, saliva or physical friction, the dyes are easy to fall off and fade, affecting the appearance, and the fallen dye molecules or heavy metal ions May be a health hazard by absorption through the skin. Therefore, auxiliaries are often used in the printing and dyeing process to improve the dyeing effect and increase the color fastness. [0003] There are many kinds of dyeing auxiliaries in the prior art, and the raw materials used in different dyeing agents are all different, and the effects achieved are not the same, but the dyeing auxiliaries in the prior art have a large number of certain differences. On the one hand, it is the selection...
