Abstract

The invention discloses a hydrophilic and darkening silicone softener, which is characterized in that it is prepared from the following raw materials in mass fractions: 100 parts of hydrophilic and darkening silicone oil; 10-50 parts of emulsifier; 0-150 parts of glycerin; acetic acid 0.5-4 parts; 100-500 parts of deionized water; the hydrophilic darkening silicone oil is prepared by mixing epoxy-terminated polyether silicone oil and polyethyleneimine. The fabric treated with the silicone softener prepared by the invention has excellent hydrophilicity, deepening effect, soft and slippery hand feeling, and good stability. The invention also provides a method for preparing a hydrophilic and darkening silicone softener and a fabric. The preparation process of the hydrophilic and darkening silicone softener provided by the invention is simple and easy, and is easy to scale up for production.

Description

technical field [0001] The invention relates to the technical field of textile finishing agents, in particular to a hydrophilic deep-enhancing silicone softener, a preparation method and a fabric. Background technique [0002] Due to the structure of fabrics, it is difficult to dye dark colors, especially fabrics with high crystallinity, and its 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 increasing to a certain extent, the effect is not obvious, and it will also increase the content of colored substances in printing and dyeing wastewater. Therefore, the method of improving the color depth of fabrics without increasing the amount of dyes has attracted more and more attention. [0003] There are three main ways to make the fabric darker: one is to roughen the surface of the fabric fiber to produce fine bumps on the surface o...
