Medical non-woven fabric breathable film

Abstract

The invention discloses a medical non-woven fabric breathable membrane. The medical non-woven fabric breathable membrane comprises a non-woven fabric layer and a composite film layer, wherein the composite film layer is adhered to the surface of the non-woven fabric layer through an adhering solvent; the specific processing technology of the non-woven fabric layer comprises the following steps: a,compounding a polyester film and polyester staple fiber hot-rolled cloth through a dry compound machine; b, then spraying a 3 to 5mg/m<2> silica gel layer onto the surfaces of the polyester film andthe polyester staple fiber hot-rolled cloth through a spray gun; c, finally performing rolling and slitting, so as to obtain a finished product, and ensuring that the thickness of the polyester film is 0.025 to 0.05mm, and the thickness is 0.08 to 0.12mm. The membrane has the advantages that cactus extract powder and peanut coat extract powder which are specially treated are added in a composite film, the membrane not only has the effect of antibacterial property, bactericidal activity and antiinflammation, but also has the characteristics of high breathability, water absorption and ultrathinproperty of the non-woven fabric layer, and is very suitable for medical bandaging, low in total cost, environmentally friendly to use, simple in processing method, and suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical non-woven breathable membrane. Background technique [0002] The breathable film is filled with calcium carbonate and other inorganic materials, and is made into a film by calendering, casting, and blow molding, and then stretched in one direction or two directions to form a breathable film. The matrix materials of domestic special materials for breathable membranes are mostly heavy calcium carbonate and light calcium as the main matrix materials, and then add an appropriate amount of unsaturated acid monomers, macromolecular coupling agents, initiators, antioxidants and other additives. The production of the special material for the breathable membrane prepared by the method needs to add many additives, the production process line is long, the preparation process is complicated, and the cost of raw materials is high. [0003] Non-woven fabrics, also known as...
