Problems solved by technology

[0003] Although the nanofiber itself has extremely excellent ability, but because the nanofiber itself does not have the function of sterilization, the dense nanofiber is easy to breed bacteria during use, which not only affects the effect of use, but also easily causes infection and affects the health of patients

Abstract

The invention discloses a medical nanofiber with sterilization and waterproof functions. The medical nanofiber comprises the following components of, in parts by weight, 60-70 parts of chitosan, 25-30parts of polylactic acid, 20-25 parts of titanium dioxide, 10-15 parts of nano-silver, 30-40 parts of sterilization liquid, 10-14 parts of formic acid, 10-12 parts of distilled water and 2-5 parts ofsilane coupling agent. According to a production process of the medical nanofiber with the sterilization and waterproof functions, bacteria attached to a nanofiber woven product are killed by using traditional Chinese medicines, so that the medical nanofiber is harmless to a human body and meets the medical standard, meanwhile, the woven product is formed by weaving nanofibers, water cannot be attached and can be easily shaken off, and the fatality rate of escherichia coli, staphylococcus aureus, candida albicans and salmonella attached to the woven surface is high.

Description

technical field [0001] The invention relates to the technical field of nanofibers, in particular to a production process of medical nanofibers with sterilizing and waterproof functions. Background technique [0002] Nanofibers have a wide range of uses, such as implanting nanofibers into the surface of the fabric, a stable gas film can be formed to make an amphiphobic interfacial fabric, which can not only waterproof, but also prevent oil and dirt; made of nanofibers Advanced protective clothing, the fabric is porous and has a membrane, which not only allows air to pass through, is breathable, but also blocks wind and filters fine particles, has barrier properties to aerosols, and can prevent biological and chemical weapons and toxic substances. [0003] Although nanofiber itself has excellent ability, but because nanofiber itself does not have bactericidal function, dense nanofiber is easy to breed bacteria during use, which not only affects the effect of use, but also easi...
