      The mask has three layers. Because in accordance with national production regulations, medical masks contain at least 3 layers of  spunbond.

       In fact, non-woven fabrics are non-woven fabrics composed of oriented or random fibers. Every family will have this material, and the most common one is the environmentally-friendly cloth bags that are kept in the elderly's homes.

       To make masks, all raw materials are polypropylene (PP), and medical masks are generally referred to as SMS structure. Among them, the spunbond layer is a single layer, and the meltblown layer can be divided into single layer or multiple layers according to filtration requirements.
