1. Spunlace non-woven fabric

The spunlace process is to spray a high-pressure fine water stream onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength.

2. Heat-sealing non-woven fabric

Thermal bonding non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcing material to the fiber web, and then the fiber web is heated, melted and cooled to form a cloth.

 3. Pulp air laid non-woven fabric

Airlaid non-woven fabric can also be called dust-free paper and dry-laid non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-flow method to agglomerate the fibers on the web curtain, and then strengthen the fiber web into a cloth.

 4.Wet non-woven fabric

The wet-laid non-woven fabric is to open the fiber raw materials in the water medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to a web forming mechanism, and the fibers are formed into a web in a wet state. Reinforce into cloth.

5. Spunbond non-woven fabric

Spunbond non-woven fabrics are formed after the polymer has been extruded and stretched to form continuous filaments. The filaments are laid into a web, and the web is then bonded by itself, thermally bonded, chemically bonded or mechanically reinforced to make The web becomes a non-woven fabric.

6.Melt blown non-woven fabric

The process of melt-blown non-woven fabrics: polymer feeding---melt extrusion---fiber formation---fiber cooling---netting---reinforcement into cloth.

7. Needle punched non-woven fabric

Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the piercing effect of needles to reinforce the fluffy web into a fabric.

8. Stitched non-woven fabric

Stitched non-woven fabric is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to

Layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combinations are reinforced to make non-woven fabrics.
