According to the different production process can be divided into:

1, Water thorn: is the high-pressure micro-flow spray to a layer or multi-layer fiber network, so that the fiber intertwined with each other, so that the fiber network to strengthen and have a certain strength.

2, heat-bonded non-woven bag: Refers to the fiber in the fiber-like or powder hot melt bonding reinforcement materials, fiber network and then through the heating and melting cooling to strengthen the cloth.

3, pulp flow into the net Non-woven bag: can also be called dust-free paper, dry paper non-woven fabric. It is the use of air flow into the network technology to open the wood pulp fiberboard into a single fiber state, and then use the Airflow method to make the fiber agglutination in the screen, fiber mesh reinforced into cloth.

4, wet-process Non-woven bag: is placed in the water medium of fiber raw materials into a single fiber, at the same time make different fiber raw materials mixed, made of fiber suspension slurry, suspended slurry into a network mechanism, fiber in the wet state into the network and then strengthened into cloth.

5, spunbonded Non-woven Bag: Is in the polymer has been extruded, stretching and forming a continuous filament, long wire laying into a network, fiber network and then through its own adhesion, thermal bonding, chemical bonding or mechanical reinforcement methods, so that the fiber mesh into non-woven fabric.

6, Melt Spray Non-woven Bag: The process: Polymer feeding-melt extrusion--fiber formation--

7, Acupuncture: is a dry non-woven fabric, needle-punched non-woven cloth is the use of needle puncture effect, will be a fluffy fiber mesh reinforcement into cloth.

8, seam: is a dry process non-woven fabric, sewing method is the use of warp knitting coil structure on the fiber network, yarn layer, non-woven materials (such as plastic sheeting, plastic thin metal foil, etc.) or their combination of reinforcement, in order to make non-woven fabric.
