Preparation method of antibacterial non-woven fabric for mask with foldable lower part

Abstract

The invention discloses a preparation method of an antibacterial non-woven fabric for a mask with a foldable lower part. The preparation method comprises the following steps that S1, proportioning iscarried out, and particularly fiber raw materials are composed of graphene oxide / polyimide composite fibers and polypropylene fibers in a mass ratio of 10-18:2-5; and S2, opening, cotton mixing, carding, antistatic treatment, lapping, drafting, hydroentangling and drying are carried out on the graphene oxide / polyimide composite fibers and the polypropylene fibers respectively to prepare the antibacterial non-woven fabric. According to the preparation method, the graphene oxide / polyimide composite fibers and the polypropylene fibers are compounded to serve as main raw materials, meanwhile, thefiber raw materials are soaked by a traditional Chinese medicine composition before opening, therefore, the antibacterial non-woven fabric prepared by opening, cotton mixing, carding, antistatic treatment, lapping, drafting, hydroentangling and drying not only has lasting antibacterial performance, has the antibacterial rate reaching up to 99.9%, but also has an excellent radiation-proof effect, and can be used for preparing the mask with the foldable lower part.

Description

technical field [0001] The invention relates to the technical field of medical product preparation, in particular to a preparation method of an antibacterial nonwoven fabric for a lower foldable mask. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are made of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. How to endow the widely used non-woven materials with excellent properties has become a hot topic at present. [0003] Non-woven fabrics are widely used, among which medical non-woven fabrics include medical masks, protective clothing, surgical gowns, isolation gowns, lab coats, nurse caps, surgical caps, doctor caps, surgical bags, maternity bags, first aid kits, diapers, pillowcases...

AI Technical Summary

Problems solved by technology

my country consumes a large amount of medical non-woven fabrics every year, but the current commercially available medical non-woven fabrics have relatively single functions, especially the medical non-woven fabrics used in medical masks. Due to the particularity of the use environment, their antibacterial and radiation protection properties The requirements are high, so there is a lack of a medical non-woven fabric that integrates antibacterial properties, radiation protection, etc.
