Problems solved by technology

[0003] At present, due to the extensive use of domestic dyes and the emergence of a large number of new structural fabrics, in the actual production process, the color of the dyed fabric is not bright enough, gray and dark, resulting in a decrease in the grade of fabric products and a decline in competitiveness. In fact, the dyeing depth The higher the color is, the better the light fastness is. When dyeing light colors, the light fastness is often unqualified
However, although the existing organic silicon or non-silicon darkening agents and brightening agents on the market can improve the color of the fabric, the effect of darkening and brightening is poor, and the darkening and reddish light make the fabric smooth and soft. Poor, lack of product stability, still can not achieve satisfactory results, and the color of the fabric will drop significantly after repeated washing, losing efficacy

Abstract

The invention discloses a smooth brightener for treating wool or wool-containing fabrics. The smooth brightener is characterized by comprising the following specific components: 5-8% of di(fatty acid alkyl ester) hydroxyethyl methyl ammonium methylsulfate, 5-10% of polyoxyethylene ether 8810, 6-9% of polyether, 3-5% of a silane coupling agent, 2-5% of polyester, 23-26% of D4 octamethylcyclotetrasiloxane, 1.5-2% of a catalyst, 0.5-1.5% of cold acetic acid and the balance of deionized water. The method for preparing the smooth brightener comprises the following steps: weighing raw materials according to a formula ratio, performing periodical stirring, and carrying out a heating reaction. The smooth brightener for treating wool or wool-containing fabrics disclosed by the invention is capable of improving the smoothness and soft hand feeling of the wool or wool-containing fabrics and achieves excellent effects of increasing color, brightening and adding luster when used for finishing of the wool fabrics.

Description

technical field [0001] The invention relates to the technical field of washing products, in particular to a smoothing and brightening agent for treating wool or wool-containing fabrics and a preparation method thereof. Background technique [0002] China's wool textile industry is the third largest textile pillar industry after cotton spinning and chemical fiber in the textile industry, and it is an industry that produces high-end textiles. At present, China's wool spinning industry is far ahead in the world's wool spinning industry, and its wool washing capacity, top processing, spinning and weaving, and clothing production all rank first in the world. China is the world's largest importer and consumer of wool raw materials, and occupies an important position in the international wool market. With the continuous emergence of new wool fabric products, the textile auxiliaries market will also develop rapidly. Therefore, the textile auxiliaries demand will increase accordingl...
