The role of Reusable medical protective clothing is to create a bacterial barrier to prevent bacterial migration and reduce cross-infection. In recent years, some scientific research units and enterprises have developed a lot of medical protective clothing, most of which are made of non-woven fabrics. Reusable medical protective clothing can be divided into woven, non-woven and composite materials according to the organizational structure of the fabric; according to the period of use, it can be divided into disposable type (one-time use), limited-time type and reusable type; according to the processing composite technology There are three types of methods: finishing, coating and lamination.

Reusable medical protective clothing has different properties due to the different raw materials used. Currently, the non-woven materials used in several medical protective clothing being sold and developed in the domestic market mainly include the following.

The protective clothing of polypropylene spunbond cloth can be treated with antibacterial and antistatic to make antibacterial protective clothing, antistatic protective clothing, etc. Compared with traditional cotton protective clothing, polypropylene spunbond protective clothing is undoubtedly a big improvement. Because of its low price and one-time use, it can greatly reduce the cross-infection rate.

Reusable medical protective clothing of polypropylene spunbond-meltblown-spunbond composite non-woven fabric, namely SMS or SMMS meltblown fabric is characterized by fine fiber diameter, large specific surface area, fluffy, soft, good drapability, low filtration resistance, The filtration efficiency is high and the hydrostatic pressure resistance is strong, but the strength is low and the wear resistance is poor, which limits the development of its application field to a considerable extent. The spunbond fiber has a higher linear density, and the fiber web is composed of continuous filaments. Its breaking strength and elongation are much larger than those of the meltblown cloth, which can just make up for the shortcomings of the meltblown cloth.
