The main fibers used for producing non-woven fabrics are polypropylene (PP) and polyester (PET). In addition, there are also PA, viscose, acrylic, HDPE and PVC. According to the application requirements, non-woven fabrics are divided into two categories: disposable and durable.

According to the production process, it is divided into:

   1. spunnon spunnon-woven fabric: spunlace technology is a high pressure micro flow of water jet to a layer or multi-layer fiber network, so that the fiber entangled together, so that the fiber network can be strengthened and have a certain strength.

   2. hot bonded nonwoven fabric: Hot bonded nonwoven fabric is a fiber reinforced or powdery hot melt adhesive reinforced material, and the fiber net is then heated and melted to reinforce the cloth.

   3. pulp air woven into non-woven fabric: airflow mesh non-woven fabric can also be called dust-free paper, dry papermaking non-woven fabric. 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: wet non-woven fabric is a fiber raw material placed in the water medium loose into a single fiber, at the same time, the different fiber raw materials mixed, made into fiber suspension pulp, suspension slurry transported to the network mechanism, fiber in the wet form of net reinforcement into cloth.

   5. spunbonded non-woven fabric: spunbonded nonwoven fabric is made of a continuous filament when the polymer has been extruded and stretched, and the filament is laid into a net. The fiber net is then bonded, hot glued, chemically bonded or mechanically strengthened to make the fiber net into nonwoven fabric.

   6. melt blown nonwovens: melt blown nonwovens process: polymer feeding - melt extrusion - fiber formation - fiber cooling - mesh - reinforcement cloth.

   7. needle punched nonwoven fabric: needle punched nonwoven fabric is a kind of dry non-woven fabric. Needle punched nonwoven fabric is made by using the puncture effect of needles, and the bulky mesh is reinforced into cloth.

   8. stitched nonwoven fabrics: stitched nonwoven fabric is a dry non-woven fabric, seaming 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.

   9. hydrophilic non-woven fabrics: mainly used for medical and health materials production, in order to obtain a better handle and scratch the skin. Like sanitary napkins and sanitary gaskets, they use the hydrophilic function of hydrophilic non-woven fabrics.
