Problems solved by technology

[0004] Due to structural limitations of the first three types of products, the fabrics after finishing are basically non-slip and have low wearing performance. The fabrics treated by these three darkening products still need to be finished with silicone handle again in the post-finishing stage.
Acrylic products are extremely rough, poor in elasticity, and poor in surface finish after the fabric is treated. Fluorine-containing raw materials for organic fluorine finishing agents also have economic and environmental problems.
[0005] Due to the rotatability of the silicone-oxygen bond, it is easy to permeate oxygen, nitrogen, etc., and the treated fabric has soft and fluffy properties and a good smooth feeling. Silicone oil and block silicone oil generally cannot achieve the ideal darkening effect

Abstract

The present invention relates to a kind of organosilicon emulsion deepening handle finishing agent and its preparation method and application, and synthesizes a comb-shaped organosilicon containing long-chain alkane, mercaptoalkyl and aminoalkyl side chains with reactivity and surface coating to increase diffuse reflection function . Due to the low refractive index of the silicone main chain and the amino hydrocarbon group, it has a strong affinity with the fabric, and the long-chain alkane can increase the surface roughness of the fabric after the finishing agent is formed into a film, increase the diffuse reflection, and can form uneven low refractive index on the fiber surface membrane. By introducing a reactive mercaptohydrocarbon group into the side chain of the silicone, based on the mercapto-ene click reaction, the reactivity with the vinyl-terminated silicone oil is improved to form a branched silicone emulsion. During fabric finishing, the complexity of the cloth surface film is increased through the framework of the branched structure, and the deepening effect of the product is further improved.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing processing and post-finishing, and in particular relates to an organosilicon emulsion darkening handle finishing agent, a preparation method and an application thereof. Background technique [0002] At present, as a traditional pillar industry in my country - the textile industry, a large amount of dye consumption and a large amount of waste water in the printing and dyeing process have brought a heavy burden to the environment and resources. With the country's vigorous rectification of the printing and dyeing industry in recent years, strict monitoring of non-environmentally friendly dyes, energy conservation and emission reduction, and technological transformation, improving product competitiveness has become an urgent task for the industry. In addition, with the promotion of new superfine fiber fabrics and the pursuit of absolute black in the Arabian region, the issue of fabric dyeing...
