Wearing disposable medical masks should undergo a facial tightness test. The simple test method is, after wearing a disposable medical mask, breathe hard, and the air cannot leak from the edge of the mask is qualified. Disposable medical mask manufacturers generally use three-layer non-woven fabrics. The middle layer is mainly used to filter air, and it is mostly made of PP non-woven fabric, and generally uses ultra-fine multilayer fibers. The main purpose of this layer is to filter fine particles, which is the source of blue for common medical masks.
The inner layer is mainly made of water-absorbable non-woven fabric. The main purpose of this layer is to absorb the water vapor exhaled by the breath. The three-layer decomposition of medical masks: the outer layer has an anti-droplet design (spunbonded nonwoven fabric) + middle layer filtration (meltblown nonwoven fabric) + moisture absorption of the inner layer (spunbonded nonwoven fabric), disposable medical mask manufacturers meltblown without Woven fabrics are generally produced with materials weighing 20 grams. The non-woven fabric layer is mostly made of high-melting-point polypropylene fiber material, which belongs to the high-melting-point fiber material of polypropylene products.
Compared with woven fabric, non-woven fabric is non-woven fabric, which is composed of fibers. The advantages are breathability, filtration, water absorption, water resistance, good hand feel, softness, and lightness, but there are also disadvantages, that is, it cannot be washed by hand.
