Briefly introduce the use of several non-woven fabrics? Non-woven fabrics, also known as non-woven fabrics, are made up of directional or random fibers and are a new generation of environmentally friendly materials, it has the characteristics of moisture-proof, breathable, flexible, light weight, no combustion-supporting, easy decomposition, non-toxic and non-irritating, rich in color, low price, and recyclable. If polypropylene is used more often (Pp material) The pellets are made of raw materials and are produced by continuous one-step process by high temperature melting, wire spraying, paving and hot pressing. It is called a cloth for its appearance and certain properties. Non-woven fabrics can be divided into: 1. Spunlaced non-woven fabrics: the high-pressure fine water flow is sprayed onto a layer or a multi-layer fiber net to tie the fibers together, so that the fiber net can be reinforced and has a certain strength. 2. Heat-bonded non-woven fabric: refers to adding fiber-like or powdery hot-melt bonding reinforcement materials to the fiber net, and the fiber net is heated, melted, cooled and reinforced into cloth. 3, pulp airflow 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 fabric: the fiber raw material placed in the water medium is loosened into a single fiber, and the different fiber raw materials are mixed to make the fiber suspension slurry, and the suspension slurry is transported to the mesh forming mechanism, the fiber is made into a net and then fixed into a cloth in a wet state. 5. Spunbonded non-woven fabric: 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 by itself, hot bonding, chemical bonding or mechanical reinforcement. Method, make the fiber mesh into a non-woven fabric. 6, blown non-woven fabric: its process: Polymer feeding---Melt Extrusion---Fiber formation---Fiber cooling---Net---Reinforced into cloth. 7, 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. 8, 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. Briefly introduce the use of several non-woven fabrics? The use of non-woven fabrics can be roughly divided :(1) Medical and sanitary non-woven fabrics: surgical gowns, protective clothing, disinfection cloth, masks, diapers, civilian rags, wipes, wet wipes, Magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloth; (2) Non-woven fabrics for home decoration: wall covering, tablecloth, bed sheets, bedspreads, etc; (3) Non-woven fabrics for clothing: lining, adhesive lining, FLOC, shaped cotton, various synthetic leather base fabrics, etc; (4)Non-woven fabrics for industry; Filter materials, insulating materials, cement packaging bags, geotextiles, coated fabrics, etc; (5) Non-woven fabrics for agriculture: Crop Protection cloth, seedling raising cloth, irrigation cloth, heat preservation curtain, etc; (6) Other non-woven fabrics: space cotton, thermal insulation and sound insulation materials, oil-absorbing felt, smoke filter, bag tea bags, etc.
