What are the uses and differences of several non-woven fabrics?

Non-woven fabrics can be divided into \x0d\ 1 according to different production processes. Spunlaced nonwovens: high-pressure micro-water is sprayed on one or more layers of fiber webs to interweave the fibers together, so that the fiber webs are strengthened and have certain strength. \x0d\ 2。 Thermal bonding nonwovens: refers to adding fibrous or powdery hot-melt bonding reinforcing materials to the web, and then heating, melting and cooling the web to strengthen it into cloth. \x0d\ 3。 Pulp airlaid nonwovens: also known as dust-free paper and dry-made nonwovens. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to bond the fibers to the net curtain, and the fiber net is reinforced into cloth. \x0d\ 4。 Wet nonwovens: fiber raw materials placed in water medium are opened into single fibers, and at the same time, different fiber raw materials are mixed to make fiber suspension slurry, which is transported to the web-forming mechanism, and the fibers are web-formed in wet state, and then reinforced into cloth. \x0d\ 5。 Spunbonded nonwovens: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a net, and then the net is transformed into nonwovens through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. \x0d\ 6。 Melt-blown nonwovens: its technological process: polymer feeding-melt extrusion-fiber forming-fiber cooling-web forming-reinforced cloth forming. \x0d\ 7。 Needle punched nonwovens: It is a kind of dry nonwovens. Needle-punched nonwovens are used to strengthen fluffy fiber webs into cloth by the puncture effect of needles. \x0d\ 8。 Sewing non-woven fabric: It is a dry non-woven fabric. The sewing method is to reinforce the net, yarn layer and non-woven materials (such as plastic sheets and plastic foils). ) or a combination thereof, by using a warp knitting loop structure. \x0d\ Uses of non-woven fabrics \x0d\ Its main uses can be roughly divided into: \x0d\ (1) Medical and health non-woven fabrics: surgical gowns, protective clothing, disinfection bags, masks, diapers, household rags, wiping cloths, wet wipes, magic towels, soft towel rolls, beauty products, sanitary napkins, etc. \x0d\ (2) Non-woven fabrics for home decoration: wall covering, tablecloth, bed sheet, bedspread, etc. ; \x0d\ (3) Nonwovens for clothing: linings, adhesive linings, fillers, profiled cotton, various synthetic leather base fabrics, etc. \x0d\ (4) Industrial nonwovens; Filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc. ; \x0d\ (5) Non-woven fabrics for agriculture: crop protection cloth, seedling cloth, irrigation cloth, thermal insulation curtain, etc. \x0d\ (6) Other non-woven fabrics: space cotton, heat and sound insulation materials, oil-absorbing felt, cigarette filter tip, tea bag in bag, etc. \x0d\ Characteristics of nonwovens \x0d\ Nonwovens break through the traditional textile principle, and have the characteristics of short technological process, high production speed, high output, low cost, wide use and many sources of raw materials.
