Classification of non-woven fabrics
The spunlace process is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs are reinforced and have a certain strength.
2. Heat-sealed non-woven fabrics
Thermally bonded non-woven fabrics refer to adding fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is then heated, melted, cooled, and reinforced into a cloth.
3. Pulp airlaid non-woven fabric
Airlaid non-woven fabrics can also be called clean paper and dry-laid non-woven fabrics. 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 then reinforced into a cloth.
4. Wet-laid non-woven fabrics
Wet-laid non-woven fabrics are to open fiber raw materials placed in an aqueous medium into single fibers, and at the same time mix different fiber raw materials to make fiber suspension pulp. Reinforced into cloth.
5. Spunbond non-woven fabrics
Spunbond non-woven fabric is 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 reinforced. The web becomes a non-woven fabric.
6. Meltblown non-woven fabric
The process of melt-blown non-woven fabrics: polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into cloth.
7. Needle-punched non-woven fabrics
Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the puncturing effect of thorn needles to reinforce the fluffy fiber web into cloth.
8. Stitched non-woven fabrics
Stitch-bonded non-woven fabrics are a kind of dry-laid non-woven fabrics. The stitch-bonding method is to use the warp-knitted coil structure to fabricate fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combinations. The body is reinforced to make a non-woven fabric.
