Abstract

The invention provides an organic silicon softening agent, a preparation method thereof and application of the organic silicon softening agent in dark fabric, and belongs to the technical field of textile finishing agents. The organic silicon softening agent provided by the invention is prepared from the following components in parts by weight: 100 parts of compound deepening crude oil, 10 to 50 parts of compound emulsifier, 0 to 100 parts of polyethylene glycol-polypropylene glycol compound, 1 to 2 parts of organic acid and 100 to 300 parts of deionized water. The organosilicon softener provided by the invention can reduce the refractive index of the surface of a fabric through after-treatment, achieves a darkening effect, enables the fabric to be soft in hand feeling, enables the hand feeling finishing and color darkening of the fabric to be carried out at the same time, is energy-saving and environment-friendly, saves dye, and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of textile finishing agents, in particular to an organic silicon softener and a preparation method thereof and application in dark fabrics. Background technique [0002] The printing and dyeing industry is an industry with high pollution and high energy consumption. Due to the structure of the fabric, it is difficult to dye dark colors, especially fabrics with high crystallinity. The dark color processing has always been a difficult problem in the dyeing and finishing industry. Increasing the amount of dye can improve the dyeing effect, but it will increase the cost, and after the increase to a certain extent, the effect is not obvious, and the content of colored substances in the printing and dyeing wastewater will also be increased. Therefore, methods to improve the color depth of fabrics without increasing the amount of dyes are gaining more and more attention. In recent years, with the continuous improv...
