What is a non-woven fabric?

Because it is a fabric that does not need spinning and weaving, it only directional or randomly propped textile staple fibers or filaments to form a fiber mesh structure, then it is reinforced by mechanical, thermal or chemical methods. Simply put, it is not interwoven and knotted by yarns one by one, but binds fibers directly through physical methods, so, when you get the stick in your clothes, you will find that you can't draw a thread. Non-woven fabric breaks through the traditional textile principle and has the characteristics of short process flow, fast production speed, high output, low cost, wide use and many sources of raw materials. Its main uses can be roughly divided :(1) Medical and health cloth: surgical clothes, protective clothing, disinfection cloth, masks, diapers, women's sanitary napkins, etc; (2) Home decoration cloth: wall covering, tablecloth, bed sheets, bedspread, etc; (3) Heel cloth: lining, adhesive lining, FLOC, shaped cotton, various synthetic leather base cloth, etc; (4) Industrial cloth: filter materials, insulating materials, cement packaging bags, geotextile, coated cloth, etc; (5) Agricultural cloth: Crop Protection cloth, seedling raising cloth, irrigation cloth, heat preservation curtain, etc; (6) Others: space cotton, insulation and sound insulation materials, oil-absorbing felt, smoke filter mouth, bag tea bags, etc. Classification of non-woven fabrics: first, the spunlaced non-woven fabric spunlaced process is to spray high-pressure fine water flow onto a layer or multi-layer fiber net to tie the fibers together, so that the fiber net can be reinforced and has a certain strength. Second, hot-bonded non-woven fabric refers to the addition of fiber-like or powdery hot-melt bonding reinforcement materials in the fiber net, and the fiber net is heated, melted, cooled and reinforced into a cloth. Three, Pulp meal air flow into a net non-woven fabric, air flow into a net non-woven fabric can also be called clean paper, dry paper Non-woven fabric. It uses the airflow forming technology to loosen the wood pulp fiberboard into a single fiber state, and then uses the airflow method to make the fiber agglomerate on the mesh curtain, and the fiber mesh is added to the cloth. 4. Wet non-woven wet non-woven fabric is to loosen 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 slurry, which is transported to the mesh forming mechanism, the fiber is made into a net and then fixed into a cloth in a wet state. Five, spunbonded non-woven fabric is after the polymer has been squeezed out and stretched to form a continuous filament, the filament is laid into a net, and the fiber net is bonded, bonded, chemically bonded or mechanically reinforced by itself, make the fiber mesh into a non-woven fabric. Six, melt spray non-woven fabric process: Polymer feeding---Melt Extrusion---Fiber formation---Fiber cooling---Net---Reinforced into cloth. Seven, acupuncture non-woven fabric is a kind of dry non-woven fabric, acupuncture non-woven fabric is to use the puncture effect of the needle to reinforce the fluffy fiber net into a cloth. Eight, sewing non-woven fabric is a kind of dry non-woven fabric, the sewing method is to use the warp coil structure to fiber mesh, yarn layer, non-textile materials (For example, plastic sheets, plastic thin metal foil, etc) Or their assemblies are reinforced to make non-woven fabrics.
