At present, some domestic enterprises have developed a variety of new medical protective clothing materials, of which woven and non-woven fabrics and composite materials are the most important three types of medical protective clothing technology. According to the type of material, there are the following: 1, polypropylene as the raw material spunbonded cloth, polypropylene material after a simple treatment with anti-bacterial anti-static function, as opposed to cotton, the price of the spunbonded fabric with polypropylene as raw material is low, and it is used only once. But the polypropylene material also has the insufficiency, it under the static condition anti-water pressure is not very high, thus to the virus barrier effect is not strong, therefore, the application scope is relatively not very widespread. 2. Wood pulp and polyester fiber composite spunlace, this composite material made of medical supplies with good resistance to alcohol, blood and oil, with non-adhesion, but also has the characteristics of high temperature resistance, can use high temperature disinfection or ultraviolet disinfection, texture is very soft. But like polypropylene, the composite is not very resistant to hydrostatic pressure, so it’s not the ideal material for medical protective clothing. 3. SMS or SMMS SMS or SMMS — “polypropylene spunbonded composite nonwovens” . Although meltblown fabrics have the advantages of large fiber surface area, good drape, fine diameter, small filtration resistance, fluffy, soft, strong anti-hydrostatic pressure ability and high filtration efficiency, the corresponding spunbonded fabrics are fibrous tissues with high linear density, with the winding of physical structure, its tensile strength and wear resistance are very good, but its low strength and poor wear resistance are the bottleneck of its development. The composite material composed of two kinds of materials, due to their respective advantages, plus a certain physical combination and processing technology, the medical protective clothing made of SMS material not only has good resistance to the invasion of pathogens, it also has excellent strength and toughness, and is a good composite material. The advantages of the composite are: beautiful appearance, high resistance to hydrostatic pressure, excellent texture and feel, good air permeability, good filtering effect and strong acid and Alkali resistance. After a number of processes, but also has a strong anti-virus, anti-serum and anti-chemical ability. Therefore, the finished SMS medical protective clothing by users at home and abroad by the praise. But it is not very strong to the solid visible particle’s protection, to some infectious diseases or the epidemic area’s protection effect is not satisfactory. 4. Flash forming NONWOVENS, which are highly waterproof and resistant to particle attack, are not as effective as this method and this material in blocking blood and body fluids. The fabric made from the coating of the high polymer, the medical protective clothing made from the high polymer material has the very good barrier property, whether it is the virus, the blood or the chemical, its barrier effect is very good. At present, whether polyethylene, polyvinyl chloride and other high polymer materials, its perspective performance and permeability are not very good, in the SARS period of use is also a necessity. The latest development at home and abroad using advanced materials such as polytetrafluoroethylene and fabric composite materials, this material is expensive, and made after only one-time use, high cost. 6. Medical protective clothing made of polyethylene breathable film and nonwovens composite cloth, polyethylene breathable film and nonwovens composite cloth has excellent resistance to bacterial penetration and penetration of liquid toxic substances, such as blood and chemical attacks. The material feels good, but also has a good air permeability and moisture permeability, to overcome the general polymer can not moisture permeability shortcomings. In addition, cost-effective is also the general hospital or medical institutions can accept, has been widely used. Our non-woven fabric drenching film can be used in the production of protective clothing&Face mask.
