Problems solved by technology

For the preparation of structural colored fabrics by colloidal microsphere deposition or self-assembly method, since the colloidal microspheres are completely assembled together by capillary force or the driving force of self-assembly, the binding force between the microspheres and the fabric surface is not strong, and it is easy to In subsequent washing and friction, the arrangement of colloidal microspheres is destroyed, thereby affecting the color effect of the fabric; in addition, this method requires a large amount of colloidal microsphere solution in the preparation process, which leads to waste of raw materials on the one hand, and on the other hand due to The deposition layer is too thick to affect the subsequent use of the fabric; the colloidal particles are very easy to self-assemble during the deposition process to produce a large amount of crystallization, and the orderly arrangement of the crystallization area leads to the preparation of the structural color fabric with obvious iridescent effect, so it is very important for the structural color The extensive use of fabric creates certain limitations
Although the structural color film prepared by electrospinning is simple and can quickly prepare similar brightly colored fabrics, the fiber film formed by bonding colloidal microspheres has very poor mechanical properties and iridescence, so it cannot get practical application

Abstract

The invention relates to a preparation method of a structural-color fabric. The preparation method comprises the following steps that ultrasonic waves and / or plasma is adopted to treat a fabric surface; P(St-MMA-AA) composite microspheres are dispersed in water to obtain a colloid emulsion, and the mass parts of the composite microspheres in the colloid emulsion is 8-15%; the colloid emulsion obtained in the step 2 is evenly mixed with a polyacrylate bonding agent and carbon black to obtain a spray dye; a treated fabric is sprayed with the spray dye to obtain a developing fabric, and then the structural-color fabric is obtained after heat setting. By adopting the method, the surface of the common fabric is coated with a layer of specially prepared structural-color fabric, accordingly the fabric is rapidly dyed with bright colors, and the structural-color fabric is also endowed with washing resistance, friction resistance, super hydrophobicity and other properties. Due to the fact that the method is low in cost, the dye-uptake rate is very high, the preparation process is simple and easy to operate, a color effect is good, the functionality is remarkable, and the preparation method is conductive to achievement of large-scale production.

Description

technical field [0001] The invention relates to the technical field of fabric preparation, in particular to a method for preparing structurally colored fabrics. Background technique [0002] The coloring of textiles is a very important link in the textile industry. At present, almost all the ways of producing color in textiles come from the process of printing and dyeing. By applying chemical colored substances (adsorbed dyes or fixed pigments) on the surface of fibers and fabrics, textiles are enriched. Colorful colors. The color of textiles mainly depends on the molecular structure of the pigment, that is, the relationship between the molecular structure of the dye or color and the absorption spectrum. However, due to the complex process of printing and dyeing, a large amount of fresh water is required as the medium for dyeing, resulting in a large amount of unused chemical dyes and auxiliaries remaining in the water to form pollution. At present, the shortcomings of hig...
