Functional SFS nonwoven fabric with characteristics of ultraviolet ray resistance, permeation resistance and moisture permeation

Abstract

The present invention relates to a functional SFS nonwoven fabric with characteristics of ultraviolet ray resistance, permeation resistance and moisture permeation. The functional SFS nonwoven fabric is characterized in that the functional SFS nonwoven fabric is formed by compounding an upper surface layer (1), a microporous moisture permeation film layer (2) and a lower surface layer (3), wherein the upper surface layer (1) and the lower surface layer (3) are made from polypropylene, and the microporous moisture permeation film layer (2) is made from a polyethylene and calcium carbonate mixing material. According to the present invention, the upper surface layer and the lower surface layer use the spunbond nonwoven fabric layers so as to ensure a certain strength, good tear resistance and good abrasion performance; the middle layer uses the microporous moisture permeation film so as to ensure good permeation resistance and good moisture permeation; and the upper layer spunbond cloth and the lower layer spunbond cloth are subjected to ultraviolet ray post-finishing processing so as to provide the anti-ultraviolet ray function, such that the SFS material has the anti-ultraviolet ray function.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a functional SFS non-woven fabric with anti-ultraviolet and anti-penetration moisture, which is mainly used as disposable products such as industrial protective clothing, isolation clothing, and surgical clothing. Background technique [0002] At present, disposable products such as medical protective clothing, isolation gowns, and surgical gowns are generally made of single-layer or double-layer non-woven cotton nets; or a plastic film layer is added between two layers of non-woven fabrics, and then bonded with glue. Made of composite non-woven fabric. The former has good air permeability, but poor waterproof, anti-alcohol, and anti-plasma permeability, which is easy to cause the invasion of bacteria and viruses, and has poor strength and is easy to tear; while the latter is on the contrary, due to the existence of the middle plastic film, increasing Its impermeability and strength make it...

AI Technical Summary

Problems solved by technology

The former has good air permeability, but poor waterproof, anti-alcohol, and anti-plasma permeability, which is easy to cause the invasion of bacteria and viruses, and has poor strength and is easy to tear; while the latter is the opposite, due to the existence of the middle plastic film, increasing Its impermeability and strength make its air permeability worse, and it is extremely uncomfortable to wear; in addition, the above-mentioned materials are disposable products, which are difficult to degrade and easily pollute the environment
