Medical masks are mostly made of one or more layers of non-woven fabrics. The main production process of medical masks includes meltblown, spunbond, hot air or acupuncture, etc., which is equivalent to resisting liquids, filtering particulates and bacteria, and is a medical protective textile. Medical masks consist of a mask and a tightening strap. Medical masks are divided into inner layer, middle layer and outer layer. The inner layer is ordinary sanitary gauze or non-woven fabric. Non-woven fabric or ultra-thin polypropylene meltblown material layer.
