What is nonwoven fabric?

The exact name of nonwoven fabric should be non-woven fabric, or non-woven fabric. Because it is a kind of fabric formed without spinning and weaving, just the textile staple fibers or filaments are oriented or randomly arranged to form a fiber network structure, and then reinforced by mechanical, thermal bonding or chemical methods. Nonwoven fabric breaks through the traditional textile principle, and has a short process, fast production speed, high yield, low cost, wide range of uses, and many sources of raw materials. \x0d\\\x0d\\ Nonwoven Advantages and Disadvantages: \x0d\ Nonwoven has many advantages: 1) Ventilation 2) Filtering 3) Thermal insulation 4) Absorbent 5) Water repellent 6) Stretchable 7) Not fluffy 8) Good handfeel, soft 9) Lightweight 10) Flexible, recoverable 11) No fabric direction 12) High productivity and fast production speed compared to textile fabric 13) Low price, mass production etc. \x0d\ Disadvantages: 1) Less strength and durability than textile 2) Cannot be washed like other fabrics 3) Fibers are arranged in a certain direction, so it is easy to split at right angles. For this reason, recent improvements in production methods have been focused on preventing splitting. \x0d\\\\x0d\\ Its main uses can be broadly divided into: \x0d\ (1) medical, health nonwoven: surgical gowns, protective clothing, disinfectant wraps, masks, diapers, civilian wipes, wiping cloths, wet wipes, magic towels, soft towel rolls, beauty supplies, sanitary napkins, sanitary pads, and disposable sanitary cloths, etc.; \x0d\ (2) non-woven fabrics for home décor: carpets, wallpapered fabrics, tablecloths, bed sheets, bedspreads, curtains, cleaning cloths, mops, etc.; \x0d\ (3) nonwoven fabrics for clothing: lining, bonded lining, wadding, shaping cotton, all kinds of synthetic leather base fabrics, etc.; \x0d\ (4) nonwoven fabrics for industrial use; automobile headliner, filtration materials, insulating materials, cement packaging bags, geotextiles, wrapping fabrics, etc.; \x0d\ (5) nonwoven fabrics for agricultural use: crop protection cloths, rice planting cloths, Irrigation cloth, thermal insulation curtains, etc. \x0d\ (6) military nonwovens: high-performance fiber bulletproof vests, gun cleaning cloth, military map base cloth, etc. \x0d\ (7) other nonwovens: space cotton, thermal insulation and soundproofing materials, oil-absorbent felt, cigarette filters, bag bags of tea bags, flags, etc. \x0d\\\x0d\ nonwoven classification \x0d\ I. Spunlaced Nonwoven \x0d\ hydroentanglement is a process in which high-pressure microscopic water is injected into a layer or layers of fibers. One or more layers of fiber network, so that the fibers are entangled with each other, so that the fiber network can be reinforced and have a certain strength. \x0d\\\\\x0d\\ Second, thermally bonded nonwoven \x0d\\ Thermally bonded nonwoven refers to the addition of fibrous or powdered hot-melt bonded reinforcing material to the fiber network, the fiber network is then heated and melted and cooled to reinforce the cloth. \x0d\\\x0d\ Three, pulp airflow into the network nonwoven \x0d\ Airflow into the network nonwoven fabric can also be called as dust-free paper, dry paper nonwoven fabric. It is the use of airflow into the network technology will be wood pulp fiber board loose into a single-fiber state, and then use the airflow method to make the fiber coagulation in the net curtain, the fiber network and then reinforced into the cloth. \x0d\\\x0d\ Four, wet nonwoven \x0d\ Wet nonwoven is placed in the aqueous medium of the fiber raw materials open into a single fiber, at the same time to make different fiber raw materials are mixed, made of fiber suspension slurry, suspension slurry conveyed to the netting mechanism, the fibers in the wet state into a net and then reinforced into a cloth. \x0d\\\x0d\ Fifth, spunbond nonwoven \x0d\ Spunbond nonwoven is in the polymer has been extruded, stretched and formed into a continuous filament after the filament is laid into a net, the fiber network and then through its own bonding, thermal bonding, chemical bonding or mechanical reinforcement methods, so that the fiber network into a nonwoven fabric. \x0d\\\\x0d\ Six, meltblown nonwoven \x0d\\ meltblown nonwoven process: polymer feeding - melt extrusion - fiber formation - fiber cooling - into the network - reinforcing into cloth. \x0d\\\\\x0d\ Seven, needle-punched nonwoven \x0d\ Needle-punched nonwoven is a kind of dry nonwoven, needle-punched nonwoven is the use of felting needles of the piercing effect of the fluffy fiber mesh reinforcing into a cloth. \x0d\\\x0d\ viii, sewing nonwoven \x0d\ sewing nonwoven is a kind of dry nonwoven, sewing method is the use of warp knitting coil structure of the fiber mesh, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.) or a combination of them to reinforce, in order to make nonwoven fabric. \x0d\ III Factors affecting the growth rate of nonwoven fabrics - \x0d\ All the factors affecting the growth of man-made fibers can have a greater or lesser impact on textiles made from man-made fibers, with the greatest impact on nonwoven textiles. \x0d\ Population growth factors have a smaller impact on nonwovens than on other textiles used in the apparel category. However, if the important application of nonwoven fabrics in baby diapers is taken into account, population growth is also an important influencing factor. \x0d\ The partial replacement of natural fibers has a greater impact on textiles, but has little effect on nonwovens, which are largely dependent on man-made fibers for their production. \x0d\ The development of man-made fibers in commerce and the specialized application of nonwovens: the establishment of international economic treaties has led to an increase in trade in microfibers, composite fibers, biodegradable fibers and new polyester fibers. This has had a significant impact on nonwovens, but not so much on apparel and knitted textiles. \x0d\ Replacement of textiles and other supplies: this includes replacement by nonwoven textiles, textiles for knitting, plastic films, polyurethane foams, wood pulp, leather and so on. This is determined by the cost and performance requirements that the product needs to have. \x0d\\\\x0d\\ Nonwoven Features Introduction\x0d\ Nonwoven fabrics are a kind of nonwoven fabrics, which is directly using polymer slices, staple fibers or filaments will be fibers through the airflow or mechanical into a network, and then after hydroentanglement, needle-punching, or hot-rolled reinforcement, and finally through the finishing of the formation of non-woven fabrics. With soft, breathable and flat structure of the new fiber products, the advantages are no fiber chips, strong, durable, silky soft, and there is a cotton feel, and cotton woven fabrics compared to non-woven bags are easy to form, and the cost is cheap. \x0d\\\x0d\\ In terms of environmental protection, the raw material for most of the non-woven fabrics currently in use is polypropylene, while the raw material for plastic bags is polyethylene, and the two substances, although they have similar names, are far apart in their chemical structures. The chemical molecular structure of polyethylene has a fairly strong stability, extremely difficult to degrade, so plastic bags need 300 years to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, which can be effectively degraded, and in a non-toxic form to enter the next step of the environmental cycle, a non-woven shopping bag can be completely decomposed within 90 days. And non-woven shopping bags can be reused more than 10 times, the degree of pollution to the environment after disposal is only 10% of plastic bags \x0d\\\x0d\ nonwoven daily products \x0d\ nonwoven disposable products are introduced \x0d\ medical nonwoven products are made of medical and health care by the use of chemical fibers, including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber Textiles. Including disposable masks, protective gowns, surgical gowns, isolation gowns, laboratory gowns, nurse caps, surgical caps, doctor caps, surgical kits, maternity kits, first-aid kits, diapers, pillowcases, bed sheets, covers, shoe covers and other disposable medical supplies series. Compared with the traditional cotton woven medical textiles, medical non-woven fabrics have the characteristics of high filtration of bacteria and dust, low surgical infection rate, convenient disinfection and sterilization, and easy to compound with other materials. Medical non-woven products as a disposable product that is disposable, not only convenient to use, safe and hygienic, but also effective in preventing bacterial infections and medical cross-infection. In China, the investment for medical and healthcare industry has reached more than one hundred billion yuan in recent years, of which the total output value of sanitary products and materials has reached about 64 billion yuan, and is developing in the direction of diversification. \x0d\\\x0d\\ Nonwoven Flour Finishing Bags \x0d\ The flour bags made of nonwoven fabric have the characteristics of light weight, environmental protection, moisture-proof, breathable, flexible, flame retardant, non-toxic, non-irritant, recyclable, etc., and are internationally recognized as an environmentally friendly product for the protection of the earth's ecology, and are widely used in all kinds of small packages of rice and flour, such as: wheat flour, corn flour, buckwheat flour. Rice and so on. This kind of non-woven products using ink printing, beautiful and generous, color realistic, non-toxic, tasteless and non-volatile, more environmentally friendly and clean than ink printing, fully meet the requirements of modern environmental protection.
