A collection of non-woven fabric types required for masks

  • Release on:2020-10-23
Due to the impact of emergencies, the demand for masks has increased due to increased equipment. Among them, medical surgical masks and N95 masks generally adopt a multi-layer structure, referred to as SMS structure: the inner and outer sides are spunbond layers (S); the middle is the meltblown layer ( M), generally divided into single layer or multilayer. Flat masks are generally PP spunbond(Nonwoven TNT Fabric Company) + meltblown + PP spunbond, and three-dimensional cup masks are generally PP spunbond + hot air cotton + meltblown + hot air cotton + PP spunbond.

It can be seen that the non-woven fabrics(TNT PP Fabric Vendor) required for masks are mainly spunbonded and meltblown, among which spunbonded non-woven fabrics(TNT Nonwoven Factory) use a relatively thick fiber diameter of about 20 microns. The process of meltblown non-woven fabric is to feed polymer-melt extrusion-fiber formation-fiber cooling-net formation-reinforcement into cloth. Meltblown fibers can reach 1-5 microns in diameter, and are generally made of polypropylene with high-melt fat fibers. These ultrafine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, thereby making meltblown fabrics With good filtering, shielding, thermal insulation and oil absorption, meltblown cloth can be called the "heart" of medical surgical masks and N95 masks. However, the domestic output of meltblown non-woven fabrics is relatively low.

Can the mask be spunlace nonwoven? It is useful, but relatively few. Nowadays, some mask companies choose to use spunlace cloth for the inner layer, because it can absorb moisture and wick away sweat, does not produce water vapor, and is soft and comfortable.
