1. Spunlace non-woven fabric    spunlace process is to spray high-pressure fine water stream onto one or more layers of fiber webs to entangle the fibers with each other so that the webs can be reinforced and have a certain strength.  2. Thermally bonded non-woven fabric    Thermally bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and the fiber web is heated, melted and cooled to reinforce the fabric.  3. Pulp air-laid non-woven fabric    air-laid non-woven fabric can also be called dust-free paper and dry paper-making 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-laid non-woven fabrics Wet-laid non-woven fabrics are used to open fiber raw materials placed in an aqueous medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to the web forming mechanism, and the fiber In the wet state, a net is formed and then reinforced into a cloth. 5. Spunbond non-woven fabric Spunbond non-woven fabric is formed 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. Combination or mechanical reinforcement method to make the web into a non-woven fabric.  6. u200bu200bMelt-blown non-woven fabric The process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into fabric.  七. Needle-punched non-woven fabrics. Needle-punched non-woven fabrics are a kind of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the piercing effect of needles to reinforce the fluffy web into a fabric. 8. Stitched non-woven fabrics Stitched non-woven fabrics are a kind of dry-laid non-woven fabrics. The stitching method uses the warp-knitted loop structure to align fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal Foil, etc.) or their combination is reinforced to make a non-woven fabric.
