Non-woven fabrics can be divided into three parts according to their production processes.
1, Spunlaced non-woven fabric: it is the high pressure micro flow of water jet to a layer or multilayer fiber network, so that the fiber entangled together, so that the fiber network can be strengthened and have a certain strength. String 5
2, heat bonded non-woven fabric: it refers to adding fibrous or powdered hot melt bonding reinforcement material into the fiber net, and the mesh is further strengthened by heating, melting and cooling.
3, pulp AIRNET, non-woven fabric: it can also be called dustless paper and dry papermaking nonwovens. It uses the air flow forming technology to loose the wood pulp fiber board into a single fiber state, and then condenses the fiber on the net curtain with the air flow method, and then the fiber net is reinforced into the cloth.
4, wet process non-woven fabric: it is the fiber raw material which is placed in the water medium to loose the single fiber. At the same time, it makes the different fiber materials mixed and makes the fiber suspension pulp. The suspension pulp is transported to the network mechanism, and the fiber is reinforced into the cloth in the wet state and then reinforced into the cloth.
5, spunbonded non-woven fabric: when the polymer has been extruded and stretched to form continuous filament, the filament is laid into a net, and the fiber net is then bonded, hot glued, chemically bonded or mechanically strengthened to make the fiber net into nonwoven fabric.
6, melt blown non-woven fabric: its technological process: polymer feeding -- melt extrusion -- fiber formation -- fiber cooling -- mesh forming -- reinforcing cloth.
7, needle punched nonwovens: dry nonwovens. Needle punched nonwoven fabrics are made by punching needles with punched web.
8, stitched non-woven fabric: a dry non-woven fabric, stitching method is to use the warp knitting coil structure for fiber mesh, yarn layer, non textile material (such as plastic sheet, thin plastic foil, etc.) or their combination to reinforce the fabric to make non-woven fabrics.
