It has the characteristics of short process flow, high output, low cost, fast variety and common raw material source. According to different consumption processes, non-woven fabrics can be divided into:
1. Spunlaced non-woven fabric: it radiates high-pressure micro water to one or more layers of fiber nets, so that the fibers are intertwined with each other, so that the fiber nets can be strengthened and have certain strength. 2. Thermal bonded non-woven fabric: refers to the fiber mesh in the form of fiber or powder hot-melt bonding reinforcement information, the fiber mesh is then heated, melted and cooled to strengthen into cloth. 3. Pulp air flow into a mesh of non-woven fabric: also known as dust-free paper, dry paper-making non-woven fabric. It uses the air flow to form a net technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the air flow method to make the fiber agglutinate on the net forming curtain, and then the fiber net is reinforced into a cloth. 4. Wet non-woven fabric: it is to loosen the fiber materials placed in the water medium into a single fiber, mix different fiber materials at the same time, and make the fiber suspension slurry. The suspension slurry is sent to the meshing mechanism, and the fiber is meshed in the wet state and then reinforced into a fabric. 5. Spunbond nonwovens: after the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a net, and then the net is made into a nonwovens by means of self bonding, thermal bonding, chemical bonding or mechanical reinforcement. 6. Melt blown non-woven fabric: its process: polymer feeding - melt extrusion - fiber composition - fiber cooling - mesh forming - reinforcement into fabric. 7. Needled non-woven fabric: it is a kind of dry non-woven fabric. Needled non-woven fabric uses the puncture effect of a needle to strengthen loose fiber mesh into cloth. 8. Sewing non-woven fabric: it is a kind of dry non-woven fabric. The sewing method is to use warp knitting coil structure to stop reinforcing the fiber net, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make non-woven fabric.
