Classification Of Non-woven Fabrics
May 10, 2018

Non-woven fabric production of fiber is mainly polypropylene (PP), polyester (PET). In addition, there are nylon (PA), viscose rayon, acrylic, ethyl lun (HDPE), VDC (PVC).

According to application requirements, Non-woven fabrics are divided into one-time application and durable type two categories.

According to the production process is divided into: 

1.spunlaced Non-woven Fabric: spunlaced technology is to spray high-pressure micro-flow to a layer or multilayer fiber network, so that the fiber intertwined with each other, so that the fiber network can be strengthened with a certain strength. 

2.Heat sealing Non-woven Fabrics: Thermal bonded non-woven fabric is the fiber network in the addition of fibrous or powdered hot-melt bonded reinforcement materials, fiber nets and then through the heating and melting cooling to strengthen the cloth. 

3. Pulp airflow into the net Non-woven fabric: The airflow into the net Non-woven fabric can also be called dust-free paper, dry paper non-woven fabrics.

It is the use of airflow into the network technology to open pine pulp fiberboard into a single fiber state, and then use the Airflow method to make the fiber agglutination in the net, the fiber net reinforced into cloth. 

4.Wet Non-woven cloth: wet Non-woven cloth is to be placed in the water medium fiber raw materials open into a single fiber, at the same time make different fiber raw materials mixed, made of fiber slurry, slurry transport to the network mechanism, fiber in the wet state into a net and then reinforced into cloth.

5.spunbonded Non-woven Fabric: spunbonded Non-woven fabric is in the polymer has been squeezed out, stretching and the formation of continuous filament, filament laying into a net, fiber nets after their own adhesion, thermal bonding, chemical bonding or mechanical strengthening methods, so that the fiber net into Non-woven fabrics. 

6.Melt-blown Non-woven fabrics: melt-blown non-woven fabric process: Polymer Feeding---melt extrusion---fiber formation---fiber cooling---into a mesh---reinforced into cloth. 

7.Acupuncture Non-woven Fabric: Acupuncture Non-woven fabric is a kind of dry non-woven, acupuncture non-woven fabric is the use of needle puncture effect, the fluffy fiber mesh to strengthen the cloth. 8.Woven Non-woven Fabric: Sewing Non-woven fabric is a dry non-woven fabric, sewing method is the use of warp-knitted coil structure on the fiber net, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination of reinforcement to make non-woven fabrics. 9. hydrophilic Non-woven Fabric: Mainly used in the production of medical and sanitary materials in order to obtain better feel and do not scratch the skin.

Like sanitary napkins, sanitary gaskets is the use of hydrophilic Non-woven fabric hydrophilic function.
