Problems solved by technology

In the existing scheme to manufacture the above-mentioned microcapsule heat-sensitive color-changing fiber fabric, the grafting mixture is directly coated on the surface of the fabric, and then dried and baked, which cannot be widely applied to various fabric substrates, and corresponds to different available fabrics. The preparation parameters of the fabric substrate and the grafting mixture need to be readjusted to adapt to the characteristics of the fabric substrate, and each preparation of the grafting mixture requires multiple trials and tests, so the cost of the process is high and the versatility is poor

Abstract

The invention relates to the field of production of chameleon fiber fabric, in particular to a chameleon fiber fabric processing technology based on graft polymerization. The processing technology comprises preparation of graft mixed liquid and coating and transferring of the graft mixed liquid, wherein the coating and transferring of the graft mixed liquid comprises the following steps of: step a, coating the graft mixed liquid on one side of release paper, baking the release paper at 110 DEG C-220 DEG C to dry the coated graft mixed liquid; and step b. coating an adhesive on the other side of the release paper, baking the release paper till the drying degree of the coated adhesive reaches 70%-80%, and adhering the side of the release paper, which is coated with the adhesive, on a fabricbase material. According to the invention, the graft mixed liquid is coated on the release paper, the release paper coated with a color-change layer is adhered on the fabric base material, and the graft mixed liquid prepared in one time can be used for different fabric base materials, thus the processing technology is convenient and quick and has low cost.

Description

technical field [0001] The invention relates to the field of production of color-changing fiber fabrics, in particular to a process for processing color-changing fiber fabrics based on a graft polymerization method. Background technique [0002] Color-changing fiber is a fiber with special composition or structure that can change color after being stimulated by external conditions such as light, heat, moisture, or radiation. For heat-sensitive color-changing fibers, one implementation is to coat the vinyl chloride mixture solution of color-changing microcapsules on the surface of the fabric, and heat-treat the solution to gel to obtain reversible heat-sensitive color-changing effects. The above-mentioned color-changing microcapsules are mainly composed of three components: a heat-sensitive color-changing pigment, a color developer that can display another color when combined with the color-changing pigment, and a component that can separate the above two components and diss...
