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.
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.
Wet-laid non-woven fabrics are to open the fiber raw materials placed in the water medium into single fibers, and at the same time mix different fiber raw materials to make fiber suspension pulp, the suspension pulp is transported to the web-forming mechanism, and the fibers are formed into a web in a wet state and then regenerated. 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.
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.
