Masks are non-woven materials, which are made of oriented or random fibers. For non-woven fabrics used in masks, the raw materials are all polypropylene (PP), and medical masks are generally multi-layered structures, commonly known as SMS structures.

From the point of view of mask materials, polypropylene high-melt non-woven special materials have become the best choice. Producing polypropylene products with melt mass flow rate of 33-41g / min, meeting Eisai polypropylene non-woven standard. From the perspective of fiber application fields, special polypropylene fiber material products are used in non-woven fabrics, apparel fabrics, carpet yarns, medical surgical supplies, and civilian hygiene products.

In terms of medical and health, non-woven fabrics produced from polypropylene non-woven special materials can be used in disposable surgical gowns, sheets, masks, cover cloths, liquid absorption pads, etc. Non-woven masks are made of fiber There are two layers in the woven fabric, and an additional layer of filter-dissolved spray cloth with a filter anti-bacteria of 99.999% is added in the middle.
