Problems solved by technology

[0003] The upper material used in cloth rubber shoes needs to be dyed. In order to enhance the color fastness of dyeing in the existing dyeing process of the upper material, it is necessary to modify the upper material with lye before dyeing. After partial hydrolysis under lye conditions, it is easy to combine with dyes
However, after hydrolysis, it will affect the mechanical properties of the upper material to a certain extent.

Abstract

The invention discloses a method for improving dyeing performance of a cloth rubber shoe vamp. The method comprises the following operation steps that 1, 6-hexanediol diacrylate, maleic anhydride andpolybutadiene are dissolved in toluene, and an initiator is added to the mixture, and polymerization reaction is carried out to obtain a polymerization solution containing a ternary polymer; the polymerization solution is subjected to reduced pressure evaporation to remove the solvent, and then water washing is performed until the pH value of a water layer is 6.5-7.5, and liquid separation is carried out, and drying treatment is performed on the obtained ternary polymer to obtain a dyeing carrier; raw materials are weighed, and a dyeing liquid is prepared; and (3) the vamp is dyed by adoptingan infrared high-temperature high-pressure dyeing machine, water washing is carried out after dyeing, and the vamp is subjected to post finishing and drying to obtain a finished product. The method for improving the dyeing performance of the cloth rubber shoe vamp is simple to operate and low in cost, the prepared cloth rubber shoe vamp is uniform in color, pure in color light, especially high incolor fastness and excellent in quality, and the service life of the cloth rubber shoes is prolonged.

Description

technical field [0001] The invention relates to the field of cloth-covered rubber shoes preparation, in particular to a method for improving the dyeing performance of cloth-covered rubber shoes vamps. Background technique [0002] Cloth rubber shoes refer to footwear products made of natural fiber, synthetic or blended fiber as the main upper material, rubber as the main outsole material, and produced by pasting and heat vulcanization. Cloth rubber shoes have the characteristics of being light to wear and easy to match with fashion, and it also has good elasticity, wear resistance and folding resistance. With the continuous advancement of science and technology and the development of various new materials, cloth rubber shoes, as a combination of technology and craftsmanship, are constantly introducing new styles and colors. Now, cloth-covered rubber shoes have become an indispensable article in national defense, sports, labor production and people's life. [0003] The uppe...
