The role of medical protective clothing is to produce a bacterial barrier layer to prevent bacterial migration and reduce cross infection. In recent years, some scientific research institutions and enterprises have developed many medical protective clothing, most of which are made of nonwoven fabrics. Medical protective clothing can be divided into woven, nonwoven and composite materials according to the fabric structure; According to the service life, it is divided into disposable type (one-time use), limited type and reusable type; According to the processing composite technology, there are three kinds of methods: finishing, coating and coating.

Medical protective clothing has different properties due to the different raw materials used. At present, the nonwoven materials used in several medical protective clothing that are being sold and developed in the domestic market mainly include the following.

The protective clothing of polypropylene spunbond fabric can be treated with anti-bacterial and anti-static treatment to make anti-bacterial protective clothing and anti-static protective clothing. Compared with traditional cotton protective clothing, polypropylene spunbond protective clothing is undoubtedly a great progress. Because of its low price and one-time use, it can greatly reduce the cross infection rate. It has been widely promoted in foreign countries for a long time.

The medical protective clothing of polypropylene spunbonded meltblown spunbonded composite nonwovens, i.e. SMS or SMMs meltblown fabrics, is characterized by fine fiber diameter, large specific surface area, fluffy, soft, good drapability, low filtration resistance, high filtration efficiency, strong hydrostatic pressure resistance, but low strength and poor abrasion resistance, which limits the development of its application field to a certain extent. The fiber linear density of spunbond fabric is large, and the fiber web is composed of continuous filaments. Its breaking strength and elongation are much greater than that of meltblown fabric, which can just make up for the shortcomings of meltblown fabric.
