Classification of non-woven fabrics

1. Spunlace non-woven fabric:
The high-pressure fine water jet is sprayed onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be reinforced and have a certain strength.

2. Heat-sealed non-woven fabrics:
It refers to adding fibrous or powdery hot-melt adhesive reinforcement material to the fiber web, and then the fiber web is heated, melted, cooled, and consolidated into a cloth.

3. Pulp airlaid non-woven fabric:
Also known as dust-free paper, dry-laid non-woven fabric. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is reinforced into a cloth.

4. Wet-laid non-woven fabrics:
The fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to make fiber suspension pulp, and the suspension pulp is transported to the web forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into cloth.

5. Spunbond non-woven fabric:
After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then self-bonded, thermally bonded, chemically bonded or mechanically consolidated to make the web non-woven cloth.

6. Meltblown non-woven fabric:
Its technological process: polymer feeding → melt extrusion → fiber formation → fiber cooling → web formation → reinforcement into cloth.

7. Needle-punched non-woven fabrics:
A kind of dry-laid non-woven fabric, needle-punched non-woven fabric is to use the puncture effect of the needle to reinforce the fluffy fiber web into cloth.

8. Stitched non-woven fabrics:
A kind of dry-laid non-woven fabric, the stitch-bonding method is to use the warp-knitted coil structure to reinforce the fiber web, yarn layer, non-woven material (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make. into non-woven fabric.
