Technical Field

The invention relates to the technical field of textile finishing agents, in particular to a hydrophilic deepening organic silicon softening agent, a preparation method and a fabric.

Background

Because of the structure of the fabric, the fabric is difficult to be dyed in dark color, particularly the fabric with high crystallinity, and the dark color processing of the fabric is always a difficult problem in the dyeing and finishing industry. The dyeing effect can be improved by increasing the dye consumption, but the cost is increased, the effect is not obvious after the dye consumption is increased to a certain degree, and the content of colored substances in the printing and dyeing wastewater is increased. Therefore, methods for increasing the color depth of fabrics without increasing the amount of dye are receiving increasing attention.

There are three main methods of deepening fabrics: firstly, roughening treatment is carried out on the surface of fabric fibers, so that fine concave-convex shapes are generated on the surface of the fibers, and a certain dark color effect can be generated by an irregular reflecting layer; secondly, the dye uptake of the dye on the textile fiber is improved, and the darkening effect is obtained by graft modification finishing, resin finishing, use of a dyeing promoter and the like; thirdly, the surface of the fabric fiber is treated by the deepening agent, a layer of low-refractive-index film can be formed on the surface of the fiber, the refractive index of the dyed fabric is reduced, and the deepening effect of the fabric is achieved under the condition that the dyeing rate is not changed. Wherein, the treatment method of the deepening agent is simple and easy to implement, and has wide application prospect. At present, the deepening agent in the market has fewer varieties and poor deepening effect, and the finished fabric is not hydrophilic and has poor hand feeling.
