Printing and dyeing auxiliary for natural pigment dyeing

Abstract

The invention discloses a printing and dyeing auxiliary for natural pigment dyeing. The printing and dyeing auxiliary is composed of the following components in parts by weight of 20 to 30 parts of coconut oil diethanolamide, 8 to 12 parts of octadecyl dimethyl benzyl amine chloride, 15 to 23 parts of sodium carboxymethylcellulose, 5 to 14 parts of sorbitan fatty acid ester, 5 to 9 parts of barium chloride, 6 to 8 parts of guar gum, 13 to 15 parts of polyethylene glycol laurate, 8 to 10 parts of polyalkyl acrylate, 8 to 10 parts of sodium dodecyl sulfate, 7 to 8 parts of polyalkyl acrylate, 6 to 7 parts of fatty alcohol, 5 to 7 parts of ethylene oxide, 2 to 3 parts of acetic acid and 9 to 24 parts of barium chloride. The printing and dyeing auxiliary for natural pigment dyeing has good effects of improving color fastness, protecting color and preventing fading through mutual combination of multiple components, can reduce the using amount of dye, is environment-friendly and non-toxic, effectively reduces the cost, can remarkably improve the color fastness of fabrics, and can be suitable for different types of fabrics.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a printing and dyeing auxiliary for natural pigment dyeing. Background technique [0002] Dyeing auxiliaries are more and more widely used in industrial production, and occupy a special and important position. Now the fabrics on the market will be printed and dyed during the preparation process, and fabrics with poor dyeing fastness will be exposed to water, perspiration, and sunlight. , saliva or physical friction, the dye is easy to fall off and fade, which affects the appearance, and the fallen dye molecules or heavy metal ions may be absorbed by the human body through the skin and endanger health. Therefore, printing and dyeing auxiliaries are often used in printing and dyeing to improve the dyeing effect and increase Color fastness etc. [0003] The process of fabric preparation involves printing and dyeing processing. Printing and dyeing auxiliaries include pri...

[0002] Dyeing auxiliaries are more and more widely used in industrial production, and occupy a special and important position. Now the fabrics on the market will be printed and dyed during the preparation process, and fabrics with poor dyeing fastness will be exposed to water, perspiration, and 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 absorbed by the human body through the skin and endanger health. Therefore, printing and dyeing auxiliaries are often used in printing and dyeing to improve the dyeing effect and increase Color fastness etc.

[0003] The process of fabric preparation involves printing and dyeing. The printing and dyeing auxiliaries include printing auxiliaries and dyeing auxiliaries. The printing auxiliaries include thickeners, adhesives, cross-linking agents, emulsifiers and other printing auxiliaries. Agents include dyeing agents, leveling agents, color fixing agents, etc. Although there are many dyeing auxiliaries in the prior art, their color enhancement and color protection properties are still not ideal, but most of the existing auxiliaries will cause skin damage. Stimulation, and the effect is relatively single. When multiple effects are required, a variety of additives need to be added, resulting in increased costs and reduced printing and dyeing effects
