Problems solved by technology

At present, fabric surface modification is a relatively mature industrial processing method, but its waterproof, oil-repellent and anti-fouling finishing agents are mostly based on fluorine-containing surfactants, which are stable in the environment for a long time, and long-term accumulation is harmful to the health of the human body and other organisms. and the environment are threatened

Abstract

A finishing method of a self-cleaning cotton fabric is disclosed. According to the method, nanometer titanium dioxide ions and rare earth elements are adopted as photocatalysts and a low-temperature plasma technology is combined to subject cotton fiber to after finishing so as to allow the cotton fiber to have a self-cleaning function. The method mainly comprises following steps of: mixing a precursor solution of titanium and a rare earth solution to prepare a self-cleaning finishing agent in a sol form, immediately dipping the cotton fabric into the self-cleaning finishing agent after the cotton fabric is subjected to low-temperature plasma processing, performing tow times of dipping and two times of rolling, taking the cotton fabric out, pre-baking and baking to obtain the self-cleaning cotton fabric. The method is simple in process, short in process and good in finishing effects. The prepared cotton fabric is obvious in self-cleaning capability, good in photocatalytic performance and high in fastness to washing and rubbing, and is lasting and durable.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, in particular to a finishing method for self-cleaning cotton fabrics. Background technique: [0002] In daily life, clothing fabrics will inevitably be stained with oil, dust and other stains, and need to be cleaned frequently. In addition to affecting the normal use of clothes, laundry sewage will also cause certain pollution to the living environment. Therefore, with the improvement of people's living standards, With the accelerated pace of life, self-cleaning fabrics have emerged as the times require. [0003] According to different self-cleaning principles, there are several ways to prepare self-cleaning fabrics: one is to coat the surface of the fabric with photocatalytic substances to release oxygen free radicals with strong The second is to change the surface structure of the textile to make the surface of the fabric highly hydrophobic and highly water-repellent; the third is t...
