Abstract

The invention provides a preparation method of a self-cleaning fabric. The method includes the following steps that, S100, 2,2'-diimidazole biphenyl and zinc nitrate hexahydrate are added into an aqueous solution of sodium dihydrogen phosphate, and mixed liquid is obtained after stirring; S200, the mixed liquid is subjected to ultrasonic vibration at 40-60 DEG C for 4-6 hours, cooled to room temperature and then filtered, and the filtered product is dispersed in isopropanol; S300, filtering is performed, filtrate is washed with a saturated sodium chloride aqueous solution, and a product is obtained after drying and mixed evenly with TiO2; S400, sodium hexametaphosphate, polyethylene glycol and sodium polyacrylate serve as a composite dispersant, and 2,2'-diimidazole biphenyl zinc / titaniumdioxide and a composite dispersant are dispersed into water to prepare a finishing agent; S500, an ultrafine polyester fabric is immersed into a finishing agent, padding is performed for 10 min, and the self-cleaning fabric is obtained after drying. Through synthesis of composite nanomaterials, after-treatment is performed by using an immersion method, the nano-photocatalytic self-cleaning fabricis prepared, the fabric has self-cleaning property, good hand feeling and air permeability.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing self-cleaning fabrics. Background technique [0002] With the continuous improvement of the quality of life of consumers, self-cleaning fabrics refer to the special properties of super-hydrophobic or photocatalytic degradation of pollutants through post-processing and finishing, so as to reduce the number of times of washing clothes or realize no-cleaning of clothes and reduce detergent. The use of energy saving, water saving and environmental friendliness are finally achieved. [0003] The photocatalytic self-cleaning fabric is prepared by loading nanoparticles with photocatalytic effect on the fabric material, so that the material can not only degrade organic pollutants through photocatalysis, but also have the ability of sterilization, deodorization and UV protection. Photocatalytic self-cleaning fabrics have become one of the hot topics in the clothin...
