Due to the wide spread of the new coronavirus epidemic and the large number of infected people, the demand for protective clothing filter materials is also increasing day by day. Medical protective clothing filter materials that meet national standards are in short supply, including PTFE protection Use filter material as a material.
The function of medical protective clothing is to create a bacterial barrier 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 use non-woven fabrics as the main fabric.
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 (one-time use), limited-time and reusable. type; in terms of processing composite technology, there are three major categories of methods: finishing, coating and lamination.
The ideal PTFE protective clothing filter material should be multi-functional. It should not only protect medical staff from toxic and harmful liquids, gases or infectious viruses and microorganisms, but also be comfortable to wear. While having barrier properties, it must also be breathable, antibacterial and anti-allergenic, and must not harm human health.
In addition, the selection of protective clothing fabrics must also consider cost and environmental issues after disposal.
The PTFE protective clothing filter material produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can obtain high dust removal efficiency. For some diameters of 0.1um-0.3um of extremely fine particles, and the filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
