1. Spunlace non-woven fabric: It sprays high-pressure fine water 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-bonded non-woven fabric: refers to adding fibrous or powdery hot-melt adhesive reinforcement material to the fiber web, and the fiber web is heated, melted and cooled to reinforce into a cloth.
3. Pulp air-laid non-woven fabric: also known as dust-free paper and dry-laid non-woven fabric. It uses air-laid technology to loosen the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and the fiber web is reinforced into a cloth.
4. Wet-laid non-woven fabric: It is 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 a fiber suspension slurry. The suspension slurry is transported to the web forming mechanism. In the wet state, a net is formed and then reinforced into a 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 bonded by itself, thermally bonded, and chemically bonded. Or mechanical reinforcement method to make the web into a non-woven fabric.
6. Melt-blown non-woven fabric: its technological process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- netting --- reinforcement into cloth.
7. Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric uses the puncture effect of a needle to reinforce the fluffy web into a cloth.
8. Stitched non-woven fabric: It is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to align the fiber web, yarn layer, non-woven Etc.) or their combination to be reinforced to make a non-woven fabric.
