What are the categories of non-woven fabrics?

What are the categories of non-woven fabrics? 1. The spunlaced non-woven spunlaced process is to spray high-pressure fine water flow onto a layer or a multi-layer fiber net to tie the fibers together, so that the fiber net can be reinforced and has certain strength. 2. Hot-bonded non-woven fabric hot-bonded non-woven fabric refers to adding fiber-like or powdery hot-melt bonding reinforcement materials to the fiber net, and the fiber net is heated, melted, cooled and reinforced into cloth. 3, pulp airflow into a net non-woven fabric can also be called clean paper, dry paper Non-woven fabric. It uses the airflow forming technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the airflow method to make the fiber agglomerate on the mesh curtain, and the fiber mesh is added to the cloth. 4. Wet non-woven wet non-woven fabric is to loosen 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 slurry, which is transported to the mesh forming mechanism, the fiber is made into a net and then fixed into a cloth in a wet state. 5, spunbonded non-woven fabric is after the polymer has been extruded, stretched to form a continuous filament, the filament is laid into a net, the fiber net is then bonded, hot bonded, chemical bonding or mechanical reinforcement method, make the fiber mesh into a non-woven fabric. 6. Process of melt-blown non-woven fabric: Polymer feeding---Melt Extrusion---Fiber formation---Fiber cooling---Net---Reinforced into cloth. 7, acupuncture non-woven fabric is a kind of dry non-woven fabric, acupuncture non-woven fabric is to use the puncture effect of the needle to reinforce the fluffy fiber net into a cloth. 8, sewing non-woven fabric is a kind of dry non-woven fabric, the sewing method is to use the warp coil structure to fiber mesh, yarn layer, non-textile materials (For example, plastic sheets, plastic thin metal foil, etc) Or their assemblies are reinforced to make non-woven fabrics.
