What kind of non-woven fabric is classified by process?

1 Spunlace nonwoven fabric: The spunlace technology is to spray high-pressure micro water into one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs are reinforced and have a certain strength. 2 Thermally bonded non-woven fabrics: Thermally bonded non-woven fabrics are fabrics made by adding fibers or powder hot-melt bonding reinforcing materials to the fiber web, and then heating, melting, and cooling. three. Pulp air-laid non-woven fabric: Air-laid non-woven fabric is also known as dust-free paper and dry paper-making non-woven fabric. It uses air-flow net technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the air-flow method to bond the fibers to the net curtain, and then reinforce the fiber net into a cloth. 4 Wet non-woven fabric: Wet non-woven fabric is to expand the fiber raw materials into single fibers in an aqueous medium, and mix different fiber raw materials to make a fiber suspension slurry. The suspension is transported to the meshing mechanism, and the fibers are meshed in a wet state and then consolidated into a cloth. 5 Spunbond nonwoven fabric: Spunbonded nonwoven fabric is formed by extruding and stretching polymers to form continuous filaments. The filamentous fibers are laid into a web, and then the web is self-bonded, thermally bonded, chemically bonded or mechanically reinforced to turn the fiber web into a non-woven fabric. 6 Melt-blown non-woven fabric: The process flow of melt-blown non-woven fabric: feeding-melt extrusion-fiber formation-fiber cooling-net formation-reinforcing cloth. 7 Needle-punched non-woven fabric: Needle-punched non-woven fabric is a dry non-woven fabric. Needle-punched non-woven fabrics use the piercing effect of needle punching to reinforce the fluffy fiber web into a cloth. 8. Sewing non-woven fabric: Sewing non-woven fabric is a dry non-woven fabric. The sewing method is to use the warp-knitted loop structure to reinforce fiber nets, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combination to make non-woven fabrics. 9 Hydrophilic non-woven fabric: mainly used in the production of medical and health care materials to get a better hand feeling and not scratch the skin. Like sanitary napkins, sanitary gaskets utilize the hydrophilic function of hydrophilic non-woven fabrics.
