According to the production process, it is divided into:
1. Spunlace non-woven fabric: The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be reinforced and have a certain force.
2. Heat-bonded non-woven fabric: heat-bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and then the fiber web is heated, melted and cooled to form a cloth.
3. Pulp air-laid non-woven fabric: Air-laid non-woven fabric can also be called dust-free paper and dry-laid non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-flow method to agglomerate the fibers on the web-forming curtain, and then strengthen the fiber web into a cloth.
4. Wet-laid non-woven fabric: Wet-laid non-woven fabric is to open the fiber raw materials placed in the water medium into single fibers, and at the same time mix different fiber raw materials to make a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are It is formed into a net in a wet state and then reinforced into a cloth.
5. Spun-bonded non-woven fabric: Spun-bonded non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is bonded by itself, thermally bonded, and chemically bonded. Or a mechanical reinforcement method to make the web into a non-woven fabric.
6. Melt-blown non-woven fabric: The process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---netting---reinforced into cloth.
7. Needle-punched non-woven fabric: Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncture effect of a needle to reinforce the fluffy fiber web into a cloth.
8. Stitch-bonded non-woven fabrics: Stitch-bonded non-woven fabrics are a type of dry-laid non-woven fabrics. The stitch-bonded method uses warp-knitted coil structures to bond webs, yarn layers, and non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) etc.) or their combination to be reinforced to make non-woven fabrics.
9. Hydrophilic non-woven fabric: mainly used in the production of medical and sanitary materials to obtain a better hand feel and not to scratch the skin. Sanitary napkins and sanitary pads use the hydrophilic function of hydrophilic non-woven fabrics.
