Problems solved by technology

The main defect of PE-coated non-woven fabrics and PE-coated non-woven fabrics produced by the prior art is that they have no moisture-permeable function, and the surgical gowns, surgical caps, bed sheets, and hole towels made of them will cover or contact the human body during use. Sweat and moisture from the body cannot escape, causing extreme discomfort
This defect is mainly because the PE film is a non-porous film through which liquid water and moisture cannot pass, so it can be waterproof and prevent blood penetration, but it does not have the function of moisture perspiration and perspiration

Abstract

The invention relates to a medical textile material, and a preparation method and an application thereof. The medical textile material comprises three layers which successively are a polypropylene non-woven fabric layer, a thermoplastic elastomer film layer and a polypropylene non-woven fabric layer from top to bottom, wherein the thickness of the thermoplastic elastomer film layer is 0.008 to 0.01 mm. According to the invention, the medical textile material with a three-layer structure is prepared by utilizing high moisture penetrability of a thermoplastic elastomer film, so protective functions of preventing water, blood and ethyl alcohol and blocking bacterial virus are guaranteed; sweat formed on the human body can be rapidly absorbed; after medical staff wear medical surgical coats, medical surgical caps, medical protective clothing or medical insulating clothing which are processed by adopting the medical textile material, the body can keep dry and comfortable; fatigue strength caused by labor is lightened; and efficiency and quality of surgery are improved.

Description

technical field [0001] The invention relates to the technical field of medical textile materials, in particular to a medical textile material and its preparation method and application. Background technique [0002] At present, the materials used in medical textiles on the market mainly include the following two types: PE coated non-woven fabric and PE coated non-woven fabric. Their purpose and function are to block bacteria and viruses to protect the safety of both doctors and patients. The structure of PE coated non-woven fabric is upper and lower layers, the upper layer is non-woven fabric, and the lower layer is PE film. Its production process is to melt PE particles to form a fluid, extrude it through a screw, apply it evenly on the non-woven fabric with a film head, and then cool it to form a PE protective film. The structure of PE coated non-woven fabric is upper and lower layers, the upper layer is non-woven fabric, and the lower layer is PE film. Its production pr...
