Product specification of nano copper powder: 1. Color: red 2. Particle size: 20 nm, 50 nm, 100 nm 3. Purity >99.5% 4. Dispersion: No hard agglomeration.

1. Antibacterial effect of copper nanoparticle : antibacterial textiles containing nano copper powder with a mass ratio of 6/1000 against red trichophyton fungi (main fungi of human skin diseases, including beriberi), Candida albicans fungi (main fungi causing gynecological diseases), The antibacterial rate of Staphylococcus aureus bacteria, Escherichia coli bacteria, etc. reaches more than 99%; and it also inhibits the mildew and mildew prevention of Aspergillus niger, Trichoderma viride, Penicillium cordatum, Chaetomium globosum etc.

2. Antibacterial mechanism of nano copper powder: Due to the small size effect of nano copper powder, the copper atoms on the surface are highly active, releasing a large amount of copper ions. The positively charged copper ions and the negatively charged cell membrane produce adsorption, and then pass through The cell wall enters the cell and reacts with sulfhydryl groups, destroying the activity of cell synthetase, causing the cell to lose its ability to divide and multiply and die, thus achieving the effect of inhibiting bacterial growth and sterilization. At the same time, after the bacteria die, copper ions will dissolve out of the bacteria Play the role of repeated sterilization. The sterilization principle of nano-copper powder does not produce resistance to bacteria, which is much better than antibiotics, and even trace amounts of copper ions are harmless to the human body even if they enter the human body, and can be naturally metabolized by the human body.

3. The method of adding fiber: firstly extrude nano-copper powder and plastic particle screw to obtain antibacterial masterbatch with a certain ultra-nano powder content, and then mix and melt together , And then spun into antibacterial fibers containing 2% nano-copper powder according to the melt spinning process requirements, and then blending the antibacterial fibers containing 2% nano-copper powder and ordinary fibers at a mass ratio of 30:70 to obtain a copper content of 1000 Six in six antibacterial daily textiles.

4. Antibacterial durability: After 50 times of washing of antimicrobial textile products containing superfine copper powder with a mass ratio of 6/1000, the antibacterial rate is still above 99%. The antibacterial effect is durable and efficient throughout the product's life cycle, and basically does not decay .

5. Copper antibacterial fiber application case: In the mine disaster in Chile in August 2010, 33 miners were trapped in a dark and wet 700-meter deep well for 69 days. The United Nations Volunteer Rescue Team sent nano-copper antibacterial fibers from the rescue channel. The socks effectively repelled the fungus on the feet, dispelled odors and prevented infections, and ensured the long-term quality of life of the miners deep underground. After successfully lifting the wells, none of the dozens of miners got beriberi. Miracle.

6. Application fields of antibacterial fibers containing nano copper powder:
1. Work clothes of doctors and nurses in hospitals, sick clothes of patients and clothes worn by caregivers.
2. Antibacterial socks, antibacterial underwear, antibacterial underwear.
3. Clothes, hats, shoes, insoles, gloves, etc.

4. Bed linen, quilt covers, pillow towels, towels, bath towels, rags and other daily-use textiles.
