Breathability and permeabilityDue to the fact that the gaps between fibers can allow air and water to enter, non-woven fabrics generally have good breathability and permeability. According to this property, non-woven fabric is often used as a filter for masks and water filtration devices.Water absor

The materials used in non-woven fabrics are roughly divided into two types: natural fibers and chemical fibers. Chemical fibers represented by polypropylene, polyethylene, polyester, nylon, etc. are more commonly used. These fibers each have different characteristics, which directly affect the funct
