Problems solved by technology

Cotton fabric itself contains more hydrophobic impurities and oils. These impurities and oils are difficult to remove during pretreatment. These all affect the inconsistent wool effect of fabric fibers, resulting in differences in moisture content and dyeing after dyeing. inequality problem
[0004] And the existing wetting liquid for fabric after dyeing, its main component is water, and a small amount of auxiliary agents are added in the water according to the difference of the fabric and the difference of the dyestuff, the surface tension of this wetting liquid is large, it is difficult to Some hydrophobic fabrics or fabrics with high oil content are wetted quickly and evenly. Therefore, the ideal uniform wettability effect cannot be achieved only through different improvements in the wetting equipment.

Embodiment Construction

[0011] 1. Accurate preparation according to its molar equivalent ratio: 0.5 mol of 1.2-epoxydodecane; 1.4 mol of hexane; 0.6 mol of sodium hydroxide; 0.3 mol of water-absorbing agent;

[0012] 2. Preparation method

[0013] Add a mixture of hexane and sodium hydroxide to 1.2-epoxydodecane under stirring conditions, and then stir at about 70°C until the reaction is complete to obtain decylethylene glycol monohexyl ether, and then in this reaction Add water-absorbing agent while stirring, and the product is obtained after stirring evenly. When using, add appropriate amount of water according to the dyeing process.

Abstract

The invention relates to a wetting agent for textile fibers and a preparation method thereof. The wetting agent for textile fibers is mainly composed of 1,2-epoxy dodecane, hexane, sodium hydroxide, water absorbent and the like. The wetting agent for textile fibers has the characteristics of small surface tension, high wetting speed, high wetting uniformity, obvious wetting effect and the like.

Description

technical field [0001] The invention relates to a wetting agent for fabric fibers and a preparation method thereof, belonging to the technical field of textile dyeing auxiliaries. Background technique [0002] The best way to obtain the color of various fiber fabrics depends on the finishing after dyeing, and to obtain the ideal effect, it is indispensable in the dyeing process to wet the strong objects. In the existing wetting process of dyeing and finishing, people often focus on the wetting equipment, and achieve the ideal wetting effect and purpose through continuous improvement and control of the equipment. From some related patents and papers published and reported at home and abroad All relate to a wetting device used in fabric dyeing, a quantitative wet supply device for fabric dyeing and the like. [0003] The above-mentioned arguments all solve the problem of uniform moisture supply of fabrics from the perspective of equipment. However, among the existing fabrics,...
