Problems solved by technology

Although the fabric after water and oil repellent finishing can reduce staining, once stains are stained, there is nothing to do; photocatalytic material finishing can remove stains on fabrics, but the fabrics finished by this method cannot prevent staining. occur
Using the synergistic effect of photocatalytic materials and water and oil repellent finishing agents to carry out composite finishing, especially the literature on polyester nonwoven fabric finishing has not been reported yet.

Abstract

The invention discloses a processing method of self-cleaning terylene non-weaving cloth. The processing method comprises the following steps: (1) preprocessing terylene non-weaving cloth; (2) preparing nanometer photocatalyst dispersion liquid: weighting 0.001-0.5g / L of unitane powder used as nanometer-level light-catalyzed material; adding 0.001-0.3g / L of polyacrylate sodium and 0.5-9.5g / L of ethanol to distilled water; stirring for 10-90 min at a speed of 30-1000r / min; ultrasonically vibrating for 10-90 min; then, stirring for 10-90 min at the same speed to obtain the nanometer photocatalyst dispersion liquid; (3) preparing composite finishing liquid: adding 5-100g / L of a water and oil repellent finishing agent Oleophobol-Co to the distilled water; stirring for 10-90 min; adding to the nanometer photocatalyst dispersion liquid to obtain composite finishing liquid; (4) padding the composite finishing liquid on the preprocessed terylene non-weaving cloth; toasting at a low temperature; and toasting at a high temperature.

Description

technical field [0001] The invention relates to a processing method of a functional fabric, in particular to a processing method of a self-cleaning polyester nonwoven fabric with antifouling and decontamination functions. Background technique [0002] For textiles, good self-cleaning performance plays a vital role in improving product quality, increasing product functions and increasing product added value. Textiles are easily contaminated with water, oil and other stains in the living and working environment during the wearing and use of the human body. These dirt not only affect the appearance of textiles and people's use, but also bring hidden dangers in hygiene. With the acceleration of people's life rhythm and the pursuit of high-quality life, consumers put forward higher requirements for the performance of textiles. People hope that textiles such as outerwear, shoe materials, and shopping bags have good water repellency, stain repellency and easy decontamination. At ...
