1, spunlace: is the high-pressure micro-jet spray to one or more layers of fiber network, so that the fibers tangled together, so that the network can be reinforced with a certain strength.

2, heat: refers to the fiber in the fiber or powder-like hot-melt adhesive reinforcement material, and then heated by heating and cooling into a cloth.

3, pulp air into the network: also known as clean paper, dry paper. It is the use of air-laid technology to open the wood pulp fiber board into a single fiber state, and then use the air flow method to agglutinate the fiber into the curtain, the fiber mesh and then reinforce the cloth.

4, wet method: is placed in the water medium fiber raw materials open into a single fiber, while the different fiber raw materials mixed, made of fiber suspension slurry, suspended pulp transported to the network into the body, the fiber in the wet state into the network again Reinforced into cloth.

5, spunbond: is the polymer has been extruded, stretching and the formation of continuous filament, the filament laying into a net, the fiber mesh and then through its own bonding, thermal bonding, chemical bonding or mechanical reinforcement method, so that Fiber mesh becomes.

6, melt blown: its process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforced into cloth.

 7, acupuncture: is a dry method, acupuncture is the use of puncture needle puncture, the fluffy fiber reinforced into a cloth.

8, stitching: is a dry method, sewing method is the use of warp knitting structure of the network, yarn layer, non-woven materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination of reinforcement To make.
