Abstract

The invention discloses a reflection-deducting coating liquid with blended soft and hard particles as well as a preparation method and application of the reflection-deducing coating liquid. The method comprises the following steps: (1) preparing hard emulsion particles, namely fully mixing an emulsifying agent with water, adding monomers for forming the hard emulsion particles and a cross-linking agent into an emulsifying agent aqueous solution, adding an initiator and residual water, reacting and performing heat preservation, thereby obtaining a hard emulsion particle aqueous dispersion; (2) preparing soft emulsion particles, namely fully mixing an emulsifying agent with a part of water, adding monomers for forming the soft emulsion particles into an emulsifying agent aqueous solution, adding an initiator and residual water, reacting and performing heat preservation, thereby obtaining a soft emulsion particle aqueous dispersion; and (3) mixing the hard emulsion particle aqueous dispersion with the soft emulsion particle aqueous dispersion, thereby obtaining the reflection-deducting coating liquid with the blended soft and hard particles. According to the coating liquid, the soft particles and the hard particles are blended to form a nano rough surface on the surface of a dacron fabric, so that reflection deduction and densification of dacron are realized and the coating liquid has extensive application prospect.

Description

technical field [0001] The invention relates to the field of textile additives and its preparation, in particular to an anti-reflection coating liquid blended with soft and hard particles, its preparation method and application. Background technique [0002] Due to polyester fiber (n f =1.73) and air (n 0 =1.0) The difference in refractive index is large, and the incident light is largely reflected by the fiber surface without being absorbed by the dye. Therefore, the color saturation of the cloth surface is poor, and it is difficult to present strong color effects such as dark green, navy blue, purple red, and black ink. And as the fiber fineness decreases, the specific surface area and reflective surface area of ​​the fabric increase, and the dyed fabric often presents a "white" visual effect. At present, the method of post-finishing is often used to achieve fabric darkening, and finishing agents are the hotspots of research. [0003] The early finishing agents were mos...
