Problems solved by technology

[0003] Existing medical protective clothing is relatively heavy, which on the one hand increases the burden on medical workers and reduces their flexibility and comfort; on the other hand, contradictions and loopholes will appear after the functions of protective clothing fabrics are superimposed, for example, While being waterproof, the air permeability of the fabric is reduced. At the same time, most of the existing medical protective clothing has poor antibacterial function, and it is difficult to ensure the efficiency of protection.

Abstract

The invention relates to an antibacterial, waterproof and moisture-permeable composite fabric and a preparation method thereof. The composite fabric consists of an outer polypropylene non-woven fabric, a TPU (thermoplastic polyurethane) film or TPE (thermoplastic elastomer) film and an inner polypropylene non-woven fabric which are stuck together sequentially; the outer polypropylene non-woven fabric and the TPU film or TPE film are stuck fixedly together through a PUR (polyurethane reactive) adhesive, i.e. a single-component moisture-curable polyurethane hot-melt adhesive, and the TPU film or TPE film and the inner polypropylene non-woven fabric are stuck fixedly together through the PUR adhesive. During preparation, the melt blending process is firstly adopted to prepare a polyether-based thermoplastic polyurethane film, and a roller coating process is then adopted to prepare the composite fabric, wherein the surface density of the outer polypropylene non-woven fabric is 10g / m<2> to 35g / m<2>, and the surface density of the inner polypropylene non-woven fabric is 15g / m<2> to 35g / m<2>; the PUR adhesive is distributed as dots, and the usage of the PUR adhesive is 3g / m<2> to 5g / m<2>. The fabric in the invention not only has the characteristics of high tension, high tensile force, toughness, aging resistance and high photostability, but also has the advantages of waterproofness, air permeability, antibacterial property and microbial penetration resistance.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to an antibacterial waterproof and moisture-permeable composite fabric and a preparation method thereof. Background technique [0002] Medical workers are people who directly communicate with bacteria and viruses. There are all kinds of germs in their working environment, especially doctors who work on the front line of infusion, trauma treatment, medical emergency, and surgical operations. They often come into contact with patients body fluids or blood, the probability of infection is very high, and its own health is often threatened. So healthcare workers have to wear protective clothing to prevent infection. [0003] Existing medical protective clothing is relatively heavy, which on the one hand increases the burden on medical workers and reduces their flexibility and comfort; on the other hand, contradictions and loopholes will appear after the functions of protective clothing ...
