Non-woven production process classification

1. The spunlace non-woven fabric spunlace process is to spray high-pressure fine water flow 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. Thermally bonded non-woven fabric Thermally bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt bonding reinforcement materials into the fiber web, and the fiber web is heated, melted and cooled to reinforce the fabric. 3. 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 net, and the fiber net is then bonded by itself, thermally bonded, and chemically bonded. Combination or mechanical reinforcement method to make the web into a non-woven fabric. 6. Melt-blown non-woven fabric The process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling---netting---reinforcement into fabric. 7. 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 cloth. 8. Stitched non-woven fabrics are a kind of dry-laid non-woven fabrics. The stitching method uses the warp-knitted loop structure to align the fiber web, 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. Purpose classification can be divided into different products according to different purposes: ⒈non-woven bag series: non-woven environmental protection bags, non-woven handbags, non-woven shopping bags, etc. ⒉Non-woven bag series: non-woven document bags, environmental shopping bags, packaging bags, non-woven handbags. ⒊Non-woven products series: non-woven storage boxes, non-woven storage boxes, non-woven suit covers and non-woven suit covers. ⒋Jewelry bag series: gift bag, rope bag, jewelry bag, flannel bag, perfume bag, pencil bag, jewelry bag, etc. ⒌Apron series: advertising apron, polyester silk apron, cotton apron, PVC apron, hanging net apron.
