According to the production process 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 web can be reinforced and have a certain strength.
2. Heat-bonded non-woven fabrics: Heat-bonded non-woven fabrics refer to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is then heated, melted, cooled, and reinforced into cloth.
3. Pulp air-laid non-woven fabrics: Air-laid non-woven fabrics can also be called clean paper and dry-laid non-woven fabrics. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is then reinforced 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 fiber suspension pulp, and the suspension pulp is transported to the web forming mechanism, The fibers are formed into a web in the wet state and then consolidated into a cloth.
5. Spunbond non-woven fabric: Spunbond non-woven fabric is after the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the fiber web is then self-bonded, thermally bonded, chemically bonded. Bonding or mechanical reinforcement methods that turn the web into a nonwoven.
6. Melt-blown non-woven fabrics: The process of melt-blown non-woven fabrics: polymer feeding—melt extrusion—fiber formation—fiber cooling—web formation—reinforcement 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 puncturing effect of a needle to reinforce the fluffy fiber web into cloth.
8. Stitch-bonded non-woven fabrics: Stitch-bonded non-woven fabrics are a kind of dry-laid non-woven fabrics. metal foil, etc.) or their combination to be reinforced to make a non-woven fabric.
9. Hydrophilic non-woven fabrics: mainly used in the production of medical and sanitary materials to achieve better hand feel and not scratch the skin. For example, sanitary napkins and sanitary pads use the hydrophilic function of hydrophilic non-woven fabrics.
