Meltblown non-woven fabric equipment technology. Meltblown cloth mainly uses 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 ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption . Can be used in the fields of air, liquid filter materials, insulation materials, absorbent materials, mask materials, thermal insulation materials, oil-absorbing materials, and wiping cloths.

Process of meltblown non-woven fabric equipment: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- forming a net --- strengthening into a cloth.

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

Medical surgical masks and N95 masks generally use a multilayer structure, referred to as the SMS structure: the inner and outer sides are a single layer of spunbond (S); the middle is a meltblown layer (M), which is generally divided into single or multiple layers.

Flat face masks are usually PP spunbond + meltblown + PP spunbond. You can also use short fibers to improve the skin feel. Three-dimensional cup-shaped masks are usually PET polyester needle-punched cotton + melt-blown + needle-punched cotton or PP spunbond. Among them, the outer layer is a non-woven fabric with a waterproof treatment, which is mainly used to isolate the droplets sprayed by the patient; the melt-blown layer in the middle is a specially-treated melt-blown non-woven fabric, which has good filtering and shielding properties. , Thermal 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 both non-woven fabrics and the raw materials are polypropylene, the manufacturing process is not the same.

The diameter of the spunbond layer fibers on the inside and outside is relatively thick, about 20 microns; the diameter of the fiber in the middle meltblown layer is only 2 microns, and it is made of a polypropylene material called high-melt fat fiber.
