Classification of non-woven fabrics
Release date:2019-03-19
According to the production process, it is divided into: 1. Spunlace non-woven fabric: The spunlace process sprays high-pressure fine water jet onto one or more layers of fiber web to entangle the fibers with each other, so that the fiber web can be reinforced and has a certain strength. .
2. Heat-bonded non-woven fabric: Thermally-bonded non-woven fabric refers to the fiber-reinforced or powdered hot-melt bonding reinforcement material in the fiber web, and the fiber web is then reinforced by heating and melting to form a cloth.
3, pulp airlaid non-woven fabric: airlaid non-woven fabric can also be called dust-free paper, dry papermaking non-woven fabric. It adopts the air-laid skill to open the wood pulp fiber board into a single fiber state, and then uses the airflow method to make the fiber condense on the mesh curtain, and the fiber mesh is further reinforced into a cloth.
4. Wet-laid non-woven fabric: The wet-laid non-woven fabric is obtained by opening a fibrous material placed in an aqueous medium into a single fiber, and simultaneously mixing different fiber materials to form a fiber suspension slurry, and transporting the suspended pulp to a networked structure. The fibers are netted in a wet state and then reinforced into a cloth.
5, spunbond non-woven fabric: spunbond non-woven fabric is after the polymer has been extruded, stretched to form a continuous filament, the filament is laid into a net, the web is then bonded by itself, thermal bonding, chemistry Bonding or mechanical reinforcement means that the web becomes a non-woven fabric.
6. Meltblown non-woven fabric: melt-blown non-woven fabric process: polymer feeding---melt extrusion---fiber composition---fiber cooling---forming into the net---reinforcing 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 is a puncture effect using a lancet, and the loose fiber web is reinforced into a cloth. 8. Non-woven fabric: Non-woven fabric is a kind of dry non-woven fabric. The stitching method uses warp-knitted coil structure, web, yarn layer and non-woven materials (such as plastic sheet, plastic sheet). The metal foil or the like or a combination thereof is reinforced to form a nonwoven fabric.
9. Hydrophilic non-woven fabric: It is mainly used for the production of medical and health materials to obtain a better hand and not to scratch the skin. For example, sanitary napkins and sanitary gaskets are hydrophilic functions using hydrophilic nonwoven fabrics.
