Abstract

The invention provides a special woolen fabric laundry detergent with softening, decontamination and anti-staining properties and a preparation method thereof. The laundry detergent is prepared from fatty alcohol ether carboxylate, isomeric tridecyl alcohol ether, an anti-staining agent, a softening agent and water; wherein in percentage by weight, the content of the fatty alcohol ether carboxylate is 12-20%, the content of the isomeric tridecyl alcohol ether is 3-7%, the content of the anti-staining agent is 2-10%, and the content of the softening agent is 0.5-3%. The special woolen fabric laundry detergent has good wetting, permeating, emulsifying and dispersing effects and the like, is high in dirt-removing power and good in cleaning effect, can effectively prevent staining and color crossing of printed and dyed wool fabrics in the process of washing reactive dye, acid dye dyeing or printing wool fabric, and can achieve the targets of complexing metal ions and softening hard water and avoid fabric defects caused by water quality.

Description

technical field [0001] The invention belongs to the technical field of detergents, and in particular relates to a special washing liquid for woolen fabrics with softness, decontamination and anti-staining properties and a preparation method thereof. Background technique [0002] Wool fabric has the characteristics of keeping warm, strong and wear-resistant, soft to the touch, soft in luster, and good in elasticity, and is loved by consumers. However, wool fabrics are not acid-resistant and alkali-resistant, so they should not be washed under alkaline conditions. If washed under alkaline conditions, the wool fabric will suffer a serious loss of strength, resulting in a decline in its wearability. In addition, wool fabrics are often dyed with weak acid dyes, neutral dyes and reactive dyes. In the washing process, the existence of unfixed dyes or hydrolyzed dyes will cause problems such as staining and color shifting of printed and dyed wool fabrics, which seriously affects t...
