Regenerable antibacterial protective fabric and preparation method thereof

Abstract

The invention discloses regenerable antibacterial protective fabric and a preparation method thereof and belongs to the technical field of medical textile materials. The regenerable antibacterial protective fabric comprises a base cloth layer, an elastic transition layer and a composite protective layer are arranged sequentially above the base cloth layer, the composite protective layer is superfine fiber formed by compositing modified polyolefin elastomer and polyurethane elastomer; the modified polyolefin elastomer is prepared by subjecting polyolefin elastomer to N-(3-dimethylaminopropyl)methylacrylamide grafting modification and chloramination; the elastic transition layer is made with polyurethane elastomer by: applying the pre-prepared elastic polyurethane superfine fiber suspensionand a superfine fiber suspension sequentially to the surface of the base cloth layer and performing chloramination. The chloramination prepared herein is applicable to the field of medical protections, such as preparation of protective garments, protective gloves or protective shoe covers.

Description

technical field [0001] The invention relates to a medical protective fabric, which belongs to the technical field of medical textile materials, in particular to a regenerable antibacterial protective fabric and a preparation method thereof. Background technique [0002] Effective medical protective materials in hospitals can cut off the possible infection hazards to medical staff caused by pathogens contained in infectious body fluids such as blood, urine, saliva, and washing fluid during surgery. [0003] At present, there are three main types of materials for medical protective clothing in my country: ordinary non-woven fabrics, rubber or coated fabrics, and protective clothing made of flash evaporation one-time forming filter materials. Among them, the protection efficiency of protective clothing made of ordinary non-woven fabrics is only about 40%, which cannot meet the minimum requirements of the national standard; the filter material made by DuPont of the United States...

AI Technical Summary

Problems solved by technology

Among them, the protection efficiency of protective clothing made of ordinary non-woven fabrics is only about 40%, which cannot meet the minimum requirements of the national standard; the filter material made by DuPont of the United States by flash evaporation has good protection performance, but the protection uniformity of the fabric is not enough , the breathability and moisture permeability are very poor, which cannot meet the wearing needs of medical staff, especially in hot summer conditions.
