Abstract

The invention discloses a method for reducing preparation cost and improving cleaning efficiency by increasing crosslinking efficiency, comprising the following steps: 1) treating a textile material with a mixed solution of a temperature sensitive copolymer, a crosslinking agent, a catalyst and a solvent; wherein the mixed solution comprises the following raw materials (by mass percent concentration): 0.1-50% of a temperature sensitive copolymer; 1-12% of a crosslinking agent; 0.1-12% of a catalyst, and the balance a solvent; 2) heating and baking the treated textile to carry out a cross-linking reaction. A cross-linked structured system composed of the fiber-crosslinking agent-temperature sensitive polymer is formed, and the temperature-sensitive polymer is fixed on the surface of the textile. The method is convenient to operate, original whiteness and flexibility of the textile will not influenced, and crosslinking efficiency and temperature sensitivity of the smart textile can be enhanced. And then, the cleaning effect of the smart cleaning textile is enhanced and the costs are reduced.

Description

technical field [0001] The invention relates to a method for reducing preparation cost and improving cleaning efficiency by improving crosslinking efficiency, specifically a method for reducing the preparation cost of intelligent cleaning textiles and improving the cleaning efficiency of textiles by improving the crosslinking efficiency of temperature-sensitive polymers and textiles Methods. By selecting a polycarboxylic acid crosslinking agent, the thermosensitive polymer is crosslinked and fixed on the surface of the textile. The multiple carboxyl groups of the polybasic acid are used to improve the crosslinking efficiency, thereby reducing the preparation cost of smart cleaning textiles and improving the cleaning efficiency of textiles. Background technique [0002] Textiles are often stained with various stains during daily wear and use. These stains not only affect the appearance of textiles and people's use, but also bring hidden dangers in hygiene; The combination i...
