Fabric plays a considerable role in decorative display and is often the main force that cannot be ignored in the entire sales space. With the development of modern textile products, industrial construction and advanced technology, the chemical fiber textile industry has shifted from pursuing total volume growth to comprehensive "technological progress" and "structural upgrading", and the demand for high-performance and multifunctional chemical fiber raw materials has continued to increase. However, at present, the research and production technology of high-performance and functional fibers in China still lags behind that of foreign countries, especially in the industrial development of functional textile materials and textile fabrics.

[0003] The negative ion release and antibacterial issues have always been an important topic in the functional development of chemical fiber fabrics. At present, there are some solutions, such as solving it from the source of the fiber, using high addition and composite spinning technology to prepare negative ion release and antibacterial fibers. The negative ion release powders used are rare earth, tourmaline, germanium oxide, etc., which are used in conjunction with antibacterial powders. Fabrics prepared with these fibers fully meet the negative ion release and antibacterial requirements of fabrics. However, this method starts from fiber production, has a long production process cycle and high requirements, resulting in high production costs, and cannot be applied to the functional improvement of ordinary fiber fabrics.

[0009] As a preferred embodiment of the present invention, the negative oxygen ion powder is a nanomaterial obtained by mixing silver, zinc, tungsten with titanium dioxide, compounding it with a thermoelectric-germanium compound, and nano-preparing it in a reactive monomer; wherein the reactive monomer can be selected from ethylene glycol.

[0010] As a preferred solution of the present invention, the soaking treatment in step three is: stirring at 60-100 r / min at a temperature of 50-70°C for 5-15 minutes, and then standing and soaking for 1-2 hours.

[0011] Beneficial effects of the present invention: The present invention uses a negative oxygen ion soaking liquid prepared from negative oxygen ion powder to soak and process the fabric composited with an antibacterial fabric layer, and forms a negative oxygen ion coating on the fabric after low-temperature drying. The resulting product has no excessive radiation, and can release high-concentration negative oxygen ions without friction or the like. The mobility of negative oxygen ions is high, and it belongs to a negative ion system that is easily absorbed by the human body.
