What is meltblown non-woven fabric? Melt-blown non-woven fabric process, melt-blown fabric(Non Woven Meltblown Fabric Vendor) is mainly made of polypropylene as the main raw material, and the fiber diameter can reach 1 to 5 microns. There are many voids, fluffy structure, and good anti-wrinkle ability. These ultra-fine fibers with unique capillary structure increase the number and surface area of ​​fibers per unit area, so that the meltblown cloth has good filtration, shielding, heat insulation and oil absorption. . It can be used in the fields of air, liquid filter materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wipe cloths.

The process of meltblown non-woven fabric(Polypropylene Meltblown Fabrics Manufacturer): polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- forming a net --- strengthening into cloth.

Meltblown cloth can be called the "heart" of medical surgical masks and N95 masks.

Medical surgical masks and N95 masks(PP Meltblown Fabrics Factory) generally adopt a multi-layer structure, referred to as SMS structure: the inner and outer sides are single-layer spunbond layers (S); the middle is the meltblown layer (M), which is generally divided into single layer or multiple layers.

Flat masks are generally PP spunbond+meltblown+PP spunbond, but one layer can also be replaced with staple fiber to improve the skin touch. Three-dimensional cup-shaped masks are generally PET polyester needle punched cotton + melt blown + needle punched cotton or PP spunbond. Among them, the outer layer is a non-woven fabric with waterproof treatment, which is mainly used to insulate the droplets sprayed by the patient; the middle melt-blown layer is a special-treated melt-blown non-woven fabric, which has good filtering and shielding properties , Heat insulation and oil absorption, are important raw materials for the production of masks; the inner layer is ordinary non-woven fabric.

Although the spunbond layer (S) and meltblown layer (M) of the mask are non-woven fabrics, and the raw materials are polypropylene, the manufacturing process is different.

Among them, the fiber diameter of the spunbond layer on the inner and outer sides is relatively thick, about 20 microns; the middle meltblown fiber has a diameter of only 2 microns and is made of a polypropylene material called high-melt fat fiber.
