The exact name of nonwovens should be nonwovens or nonwovens. Because it is a kind of fabric formed without spinning and weaving, it is only formed by orienting or randomly arranging textile short fibers or filaments to form a network structure, and then strengthening it by mechanical, thermal bonding or chemical methods. Nonwovens break through the traditional textile principle and have the characteristics of short technological process, fast production speed, high output, low cost, wide application and many sources of raw materials. \x0d\x0d\ Advantages and disadvantages of non-woven fabrics: \ x0d \ Non-woven fabrics have many advantages: 1) breathability 2) filtration 3) heat insulation 4) water absorption 6) flexibility 7) no mess 8) good hand feel, softness 9) portability 10) elasticity and recoverability. \x0d\ Disadvantages: 1) Compared with woven fabric, it has poor strength and durability; 2) Can't be cleaned like other fabrics; 3) fibers are arranged in a certain direction, which is easy to crack at right angles, and so on. Therefore, the recent improvement of production methods mainly focuses on the improvement of preventing division. \ x0d \ 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, sanitary pads and diapers. \x0d\ (2) Non-woven fabrics for home decoration: carpets, wall stickers, tablecloths, sheets, bedspreads, curtains, scouring pads, mops, etc. \x0d\ (3) Nonwovens for clothing: linings, adhesive linings, fillers, profiled cotton, various synthetic leather base fabrics, etc. \x0d\ (4) Industrial nonwovens; Automobile roof tarpaulin, filter material, thermal insulation 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) Military non-woven fabrics: high-performance fiber body armor, gun cleaning cloth, military map base cloth, etc. \ x0d \ (7) Other non-woven fabrics: space cotton, heat and sound insulation materials, oil-absorbing felt, cigarette filter tips and packaging bags. X0d\ Spunlacing process is to spray high-pressure micro-water on one or more layers of fiber web, so that the fibers are interwoven with each other, and the fiber web is strengthened and has certain strength. \x0d\ x0d \ II。 Thermal bonding nonwovens \ x0d \ Thermal bonding nonwovens refer 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\\x0d\ III。 Pulp airlaid nonwovens \x0d\ airlaid nonwovens can also be called dust-free paper and dry papermaking 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\ x0d \ IV。 Wet nonwovens \ x0d \ Wet nonwovens are made by opening fiber raw materials placed in water medium into single fibers, and mixing different fiber raw materials to make fiber suspension slurry, which is conveyed to the web-forming mechanism, and the fibers are web-formed in wet state and then reinforced into cloth. \ x0d \ x0d \ v. Spunbonded nonwovens \ x0d \ Spunbonded nonwovens are made by laying the filaments into a net after the polymer is extruded and stretched to form continuous filaments, and then the net is thermally bonded, chemically bonded or mechanically bonded. \x0d\ x0d \ VI。 Melt-blown nonwovens \ x0d \ The technological process of melt-blown nonwovens: polymer feeding-melt extrusion-fiber forming-fiber cooling-web forming-reinforced fabric forming. \x0d\\x0d\ VII。 Needle-punched nonwovens \x0d\ Needle-punched nonwovens are dry nonwovens. Needle-punched nonwovens are used to strengthen fluffy fiber webs into cloth by the puncture effect of needles. \x0d\ x0d \ VIII。 Sewn nonwovens \ x0d \ Sewn nonwovens are dry nonwovens. Sewing nonwovens are made of reinforcing mesh, yarn layers and nonwovens (such as plastic sheets and plastic foils). ) or their combination with warp knitting coil structure. \x0d\ III。 Factors affecting the growth rate of non-woven fabrics -\ x0d \ All factors affecting the growth of man-made fibers can have a certain impact on textiles made of man-made fibers to a certain extent, among which non-woven fabrics have the greatest impact. \x0d\ Compared with other textiles used in clothing, population growth factors have less influence on non-woven fabrics. However, if we consider the important application of non-woven fabrics in baby diapers, population growth is also an important influencing factor. \x0d\ Partial substitution of natural fibers has great influence on textiles, but little influence on non-woven fabrics, because the production of non-woven fabrics basically depends on man-made fibers. \x0d\ Commercial development of man-made fibers and specialized application of non-woven fabrics: Due to the establishment of international economic treaties, the trade of microfibers, composite fibers, biodegradable fibers and new polyester fibers has increased. This has a great influence on non-woven fabrics, but has little influence on clothing and knitted textiles. \x0d\ Substitute textiles and other items: This includes being replaced by non-woven fabrics, knitted textiles, plastic films, polyurea foam, wood pulp, leather, etc. This is determined by the cost and performance requirements of the product. \x0d\ x0d \ Characteristics of nonwovens \ x0d \ Nonwovens are nonwovens, which are made of polymer chips, short fibers or filaments by air flow or machinery, then reinforced by spunlace, needle punching or hot rolling, and finally finished. The new fiber products have the advantages of softness, breathability and plane structure, and have the feeling of no fiber crumbs, tenacity, durability, silky softness and cotton. Compared with cotton fabric, non-woven bag is easy to form and has low manufacturing cost. \ x0d \ x0d \ In terms of environmental protection, the raw material of most non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of these two substances are similar, their chemical structures are quite different. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade, so it takes 300 years for plastic bags to decompose. However, the chemical structure of polypropylene is not firm, and the molecular chain is easily broken, so it can be effectively degraded and enter the next environmental cycle in a non-toxic form, and a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused for more than 10 times, and the environmental pollution after being discarded is only about 10% of that of plastic bags \x0d\ non-woven daily necessities \ x0d \ introduction of non-woven disposable products \ x0d \ medical non-woven products are made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber. Including disposable masks, protective clothing, surgical clothing, isolation clothing, laboratory clothing, nurses' hats, surgical hats, doctors' hats, surgical bags, pregnant women's bags, first aid bags, diapers, pillowcases, bed sheets, quilt covers, shoe covers and other disposable medical consumables. Compared with traditional cotton woven medical textiles, medical nonwovens have the characteristics of high filtration to bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy compounding with other materials. As a disposable product, medical nonwoven products are not only convenient, safe and hygienic, but also can effectively prevent bacterial infection and iatrogenic cross-infection. In China, in recent years, the investment in medical and health industry has reached 1000 billion yuan, of which the total output value of sanitary products and materials is about 64 billion yuan, and it is developing in a diversified direction. \x0d\x0d\ non-woven flour hardcover bag \ x0d \ flour bag is made of non-woven, which is light, environmentally friendly, moisture-proof, breathable, flexible, flame-retardant, non-toxic, non-irritating and recyclable.
