Popularization of textile knowledge: the use of several non-woven fabrics

According to different production processes, non-woven fabrics can be divided into: 1. Spunlace non-woven fabrics: high-pressure fine water jets are sprayed onto one or more layers of fiber webs to entangle the fibers together, so that the fiber webs can be strengthened. Have a certain strength. 2. Heat-bonded non-woven fabric: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials 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 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 fabric: the fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to form a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are in a wet state. Form a net and then reinforce 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, chemically bonded or mechanically reinforced 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 piercing 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 fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or Their combination is reinforced to make a non-woven fabric. The main uses of non-woven fabrics can be roughly divided into: (1) Medical and sanitary non-woven fabrics: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, wet wipes, magic Towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths, etc.; (2) Non-woven fabrics for home decoration: wall coverings, table cloths, bed sheets, bedspreads, etc.; (3) None for clothing Woven fabric: lining, fusible interlining, wadding, shaped cotton, various synthetic leather base fabrics, etc.; (4) Industrial non-woven fabrics; filter materials, insulating materials, cement packaging bags, geotextiles, covering fabrics, etc.; (5) Agricultural non-woven fabrics: crop protection cloth, seedling cloth, irrigation cloth, thermal insulation curtain, etc.; (6) Other non-woven fabrics: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. The characteristics of non-woven fabrics Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials.
