Abstract

The invention relates to a composite electrostatic spinning micro-nano fiber antibacterial non-woven sanitary material and a preparation method thereof. The composite electrostatic spinning micro-nanofiber antibacterial non-woven sanitary material is formed by compounding antibacterial micro-nano fibers and a non-woven material, and the reliable antibacterial effect can be achieved on the basis that the original performance of the non-woven sanitary material is not changed. The micro-nano antibacterial sanitary material has excellent antibacterial and bacteriostatic effects, and can be applied to various sanitary materials such as paper diapers, surgical gowns, female sanitary towels and other sanitary products.

Description

Technical field [0001] The invention belongs to the field of sanitary materials and their preparation, and particularly relates to a composite electrostatic spinning micro-nano fiber antibacterial nonwoven sanitary material and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the market for disposable nonwoven sanitary materials has developed rapidly, and people's demand for disposable sanitary materials has soared. In the 21st century, people are increasingly favoring functional non-woven sanitary materials. [0003] Currently, non-woven sanitary materials using natural antibacterial fibers generally have the problems of high cost and low antibacterial properties, which limit the popularization and development of products. However, the antibacterial sanitary materials prepared by antibacterial agents directly contact human skin, which has the problem of low safety. [0004] CN 105839291A discloses a nanofiber antibacter...
