Problems solved by technology

[0002] Known heat-clearing and detoxifying Chinese herbal medicine has good antibacterial and antiviral activity, low toxicity, and is not easy to produce drug resistance. Now it can be sprayed with traditional Chinese medicine fine powder to prepare toilet paper, and hygroscopic composite paper materials for hygroscopic products. Polyvinyl alcohol fiber membrane, activated carbon Fiber membranes loaded with silver or inorganic bactericidal substances such as silver-loaded chlorine can kill Escherichia coli and Staphylococcus aureus in water and air, but the existing membrane materials and paper are limited by drug loading and mechanical strength. Easy desorption, high toxicity, limited antibacterial spectrum, insensitive to viruses, so its antibacterial and antiviral activity is not ideal as a health protection material
