Background

The Photocatalyst is a TiO compound₂As a general term of typical photocatalytic semiconductor materials, various organic compounds and some inorganic substances are oxidized and decomposed, and proteins which can destroy cell membranes of bacteria and solidify viruses are formed, and a permanent antibacterial antifouling coating film can be formed on the surface of the material, and the material absorbs ultraviolet rays, has a photocatalytic oxidation function, and has extremely strong antifouling, bactericidal and deodorizing functions. Can effectively degrade toxic and harmful gases in the air; can effectively kill various bacteria, has the antibacterial rate of 99.99 percent, and can decompose and harmlessly treat toxins released by bacteria or fungi; meanwhile, the paint also has the functions of deodorization, stain resistance and the like.

With the development of society and the improvement of living standard, the requirements of people on living quality are higher and higher, various garment products are fully available in the market, and the garment materials are also endless. The knitted product is used as a close-fitting product for people and directly contacts the skin of people. Besides the conventional covering and warming functions, the function of body health is extended, so that the positioning of the knitted fabric is a skin-care textile beneficial to body health for 24 hours, which is the development direction of the future knitting industry. However, the current knitting enterprises face development pressure in various aspects such as raw material price rising, labor tightening, labor cost increasing and the like, research and develop functional knitwear and increase the proportion of high-end knitwear, and further increase the added value of products and market competitiveness. Therefore, the research and development of the functional knitting new product have important practical significance for knitting enterprises.

The photocatalyst material can be applied to various fields at present, photocatalyst fibers are applied to the knitting industry, good bactericidal property and health care property can be given to fabrics, at present, researchers have developed the photocatalyst fibers, when the photocatalyst fibers are applied to the fields of textile fabrics and the like, in the processing process of photocatalyst knitwear, complex relations exist between dyeing and finishing process technology and the like and final functions and wearability of the fabrics, but the current research basically stays in the research stage, and industrial production cannot be realized.

However, since the photocatalyst materials are all nanoscale powder materials, if the photocatalyst materials are not fixed well, the photocatalyst materials can pass through a respiratory system; or skin contact; or enter human body to become foreign pollutant by eating, etc., and react with in vivo cells to cause inflammation, pathological changes, etc.; the retention of contaminants in body tissues may also cause lesions, e.g. asbestos fibres retained in the lungs may lead to lung fibrosis.
