Non-woven fabrics can be divided into:
1. Spunlace non-woven fabric: it is to spray high-pressure micro-water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber web can be strengthened and has a certain strength.
2. Heat-sealed non-woven fabric: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and then heating, melting, and cooling to strengthen the fiber web into a cloth.
3. Wet non-woven fabric: the fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to form a fiber suspension slurry, and the suspension slurry is transported to the web forming mechanism, and the fibers are in a wet state The net is then reinforced into cloth.
4. Melt-blown non-woven fabric: its technological process: polymer feeding-melt extrusion-fiber formation-fiber cooling-netting-reinforcement into cloth. The most important layer in the face mask is the melt-blown non-woven fabric, which can effectively block dust, bacteria and viruses in the air.
5. Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of the needle to strengthen the fluffy web into a cloth.
