Nonwoven Fabric Details

Non Woven Fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because it has the appearance and certain properties of cloth.

Nonwoven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic, non- *** sex, colorful, inexpensive, recyclable and so on. Such as the use of polypropylene (pp material) granules as raw materials, high temperature melting, spraying, laying the outline, hot pressing and winding continuous one-step production and become.

Basic introduction Chinese name ：Non-woven fabric Foreign name ：Non-woven fabric Alias ：Non-woven fabric, nonwoven fabric Material ：Oriented or random fibers Characteristics,Maintenance,Usage,Classification,Difference,History,Main products,Nonwoven quilting,Disposables,Flour bags,Fashion shopping bags, Features Nonwoven fabric has no warp and weft threads, it's very easy to cut and sew, and it is lightweight and easy to shape, popular with handmade fabrics. It is light and easy to shape, which is loved by handmade enthusiasts. Because it is a kind of fabric formed without spinning and weaving, only 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. It is not interwoven and knitted together by one yarn after another, but the fibers are directly bonded together by physical methods, so when you get the sticky claim in your clothes, you will find that it is not possible to draw a single thread. Nonwoven fabric breaks through the traditional textile principle, and has a short process, fast production rate, high yield, low cost, wide range of uses, raw material sources and so on. The relationship between nonwoven fabrics and spunbond fabrics Spunbond fabrics and nonwoven fabrics are subordinate. The manufacture of nonwoven fabrics has many production processes, in which spunbond is one of the nonwoven production process (including spunbond, meltblown, hot-rolled, spunlace, most of the nonwoven fabrics on the market are spunbonded nonwoven fabrics) Spunbond Nonwoven Fabrics Nonwoven fabrics according to the composition, there are polyester, polypropylene, spandex, spandex, acrylics, etc.; the different components will have a very different style of nonwoven fabrics. The nonwoven fabric style. Spunbond fabrics, on the other hand, usually refer to polyester spunbond and polypropylene spunbond; and the styles of these two types of fabrics are very close to each other, and can only be discerned through high-temperature testing. Nonwoven fabric is a kind of nonwoven fabric, it is directly using polymer slices, staple fibers or filaments will be fiber through the airflow or mechanical into a network, and then through the 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, but also a kind of reinforcing materials, and there is a cotton feeling, and cotton woven fabrics compared to the nonwoven bags easy to form, and cheap. Advantages: 1. Lightweight: polypropylene resin as the main raw material, specific gravity of only 0.9, only three-fifths of cotton, with fluffy, feel good. 2. 2. Soft: composed of fine fibers (2-3D) light point-like hot melt bonding molding. The finished product is moderately soft, with a sense of comfort. 3, water, breathable: polypropylene slices do not absorb water, water content of zero, the finished dial water good, composed of 100% fiber with porous, breathable, easy to keep the cloth dry, easy to wash. Polypropylene Nonwoven Fabric 4. Non-toxic, non- *** sex: the product is in line with the FDA food-grade raw materials production, does not contain other chemical components, stable performance, non-toxic, no odor, not *** skin. 5. Antibacterial, anti-chemicals: polypropylene is a chemical blunt substance, not insect, and can isolate the presence of bacteria and insects within the liquid erosion; antimicrobial, alkali corrosion, the finished product does not affect the strength of erosion. 6. Antibacterial. Products with water pulling, not moldy, and can isolate the existence of bacteria and insects in the liquid erosion, not moldy. 7. Good physical properties. Spun by the polypropylene directly laid into a network of thermal bonding and become, product strength than the general short-fiber products for the better, the strength of non-directional, similar to the strength of the longitudinal and transverse direction. 8. In terms of environmental protection, the use of most of the raw materials of non-woven fabrics is polypropylene, while the raw material of plastic bags is polyethylene, two substances, although the name is similar, but in the chemical structure is far from each other. Polyethylene's chemical molecular structure has a fairly strong stability, extremely difficult to degrade, so plastic bags need 300 years to decompose; and polypropylene's chemical structure is not strong, the molecular chain can be easily broken, which can be effectively degraded, and in the non-toxic form to enter the next step of the environmental cycle, a non-woven shopping bags in 90 days can be completely decomposed. And non-woven shopping bags can be reused more than 10 times, after the disposal of the environmental pollution degree is only 10% of the plastic bag. Disadvantages: 1) Compared with textile fabric strength and durability is poor. 2) Can not be cleaned like other fabrics. (3) The fibers are arranged in a certain direction, so it is easy to split from the right angle direction and so on. Therefore, the improvement of the production method is mainly focused on the improvement to prevent splitting. Maintenance of nonwoven fabrics: nonwoven fabrics in the maintenance and collection should pay attention to the following points: 1, to keep clean, often change and wash, to prevent moths from breeding. 2, seasonal storage, must be washed, ironed, dried sets of plastic bags after sealing, flat in the closet. Pay attention to the light, in order to prevent color fading. It should be ventilated frequently, dusted and dehumidified, and not exposed to the sun. Closet should be put into the mold, moth tablets, so as to avoid the cashmere products damp mold and insects. 3, when worn with its matching outerwear lining to be smooth, pockets should not be loaded with hard objects such as pens, key packets, cell phones, etc., to avoid local friction balling. Wear outside to minimize friction with hard objects (such as sofa backrests, armrests, desktop) and hooks. Wearing time is not too long, 5 days or so to stop wearing or change wearing, so that the clothing to restore the elasticity, so as to avoid fiber fatigue damage. 4, such as pilling, can not be forced to pull, must be cut off with scissors pom pom, so as to avoid offline and can not be caused by repair. Uses Nonwoven products are colorful, bright and vivid, fashionable and environmentally friendly, widely used, beautiful and generous, with a variety of patterns and styles, and lightweight, environmentally friendly, recyclable, and internationally recognized as an environmentally friendly product to protect the earth's ecology. Applicable to agricultural film, shoes, leather, mattresses, mother and child quilt, decoration, chemical, printing, automotive, building materials, furniture and other industries, and clothing linings, medical disposable surgical gowns, masks, hats, sheets, hotel disposable tablecloths, beauty, sauna and even today's fashionable gift bags, boutique bags, shopping bags, advertising bags and so on. Environmental protection products, wide range of uses, affordable. Because of its pearl-like appearance, also known as pearl canvas. Nonwoven Fabric Nonwoven fabrics by including chemical fibers and plant fibers in water or air as a suspension medium under the conditions of the wet or dry method of paper machine made, although the cloth without textile so it is called nonwoven fabrics.

Classification The fibers used in the production of nonwoven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are polyamide (PA), viscose fiber, acrylic, polyethylene (HDPE), polyvinyl chloride (PVC). According to the set of requirements, nonwoven fabrics are divided into two categories: disposable set of type and durable type. According to the production process is divided into: PET polyester nonwoven fabric 1. Spunlace nonwoven fabrics: Spunlace process is a high-pressure micro-fine water jet to a layer or layers of fibers on the fiber network, the fibers are entangled with each other, so that the fiber network can be reinforced with a certain strength. 2. Heat bonded nonwoven fabrics: heat bonded nonwoven fabrics refers to the fiber network in the addition of fibrous or powdered hot melt bonding reinforcement materials, fiber network and then heated and melted and cooled into a cloth reinforcement. 3. Pulp airflow into the net nonwoven fabric: airflow into the net 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 open 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 a cloth. 4. Wet nonwoven fabrics: wet nonwoven fabrics are placed in aqueous media fiber raw materials into a single fiber, while making different fiber raw materials are mixed, made of fiber suspension slurry, suspension slurry transported to the netting mechanism, the fibers in the wet state into the net and then reinforced into cloth. 5. Spunbond nonwoven fabric: spunbond nonwoven fabric is in the polymer has been extruded, stretched and formed a continuous filament, filament laying into the net, fiber network and then after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement methods, so that the fiber network into a nonwoven fabric. 6. Meltblown nonwoven fabrics: meltblown nonwoven fabrics process: polymer feeding - - melt extrusion - - fiber formation - - fiber cooling - - into the network - - reinforcement into cloth. 7. Needle-punched nonwoven fabrics: needle-punched nonwoven fabrics is a kind of dry nonwoven fabrics, needle-punched nonwoven fabrics is the use of felting needles to puncture the role of the fluffy fiber mesh reinforced into a cloth. 8. Sewing nonwoven: sewing nonwoven is a dry nonwoven, sewing method is the use of warp knitting coil structure on the fiber network, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.) or a combination of them to reinforce the nonwoven fabric. 9. Hydrophilic nonwoven fabrics: mainly used in the production of medical and hygienic materials, in order to achieve a better feel and not scratch the skin. Like sanitary pads, sanitary pads is the use of hydrophilic nonwoven hydrophilic function. Difference between nonwoven fabrics and dust cloth nonwoven fabrics, also known as non-woven fabrics, is a new generation of environmentally friendly materials, with water repellency, breathable, flexible, non-combustible, non-toxic, non- *** sex, rich in color and other characteristics. Nonwoven fabrics, if placed outdoors by natural decomposition, its longest life is only 90 days, placed indoors in 5 years decomposition, combustion is non-toxic, odorless, and no residual material, so as not to pollute the environment, suitable for washing. It directly uses polymer slices, staple fibers or filaments through a variety of fiber network forming methods and cementing technology to form a new type of fiber products with soft, breathable and flat structure. It has the environmental protection performance that plastic products do not have, and its natural degradation time is much lower than that of plastic bags, therefore, the non-woven bags made of non-woven fabrics are also recognized as the most affordable and environmentally friendly shopping bags. Dust free cloth is made of 100% polyester fiber double weave, soft surface, easy to wipe sensitive surfaces, friction does not shed fiber, has good water absorption and cleaning efficiency. Cleaning and packaging of the products are done in an ultra-clean workshop. Dustless cloth optional sealing generally have: cold cutting, laser sealing, ultrasonic sealing. Microfiber dust free cloths are usually sealed with laser and ultrasonic perfect edges; Dust free cloths, dust free wiping cloths, microfiber dust free cloths, microfiber wiping cloths are made of 100% continuous polyester fiber double weave cloth with soft surface, which can be used to wipe sensitive surfaces, with low dust production and friction without removing fibers, and with good water absorbency and cleaning efficiency. It is especially suitable for dust free cleanroom. The edges of dust free cloth, dust free wiping cloth, microfiber dust free cloth, microfiber wiping cloth are sealed by the most advanced edge-cutting machine, which will not leave particles and threads after wiping, and has strong ability to remove dirt. History I. The development of nonwoven textile industry As of 1998, the worldwide consumption of nonwoven fabrics has reached 2.4 million tons. In 1970, its consumption was only 400,000 tons, and by 2007, its consumption is expected to reach 4 million tons. Producers of nonwoven fabrics are mainly concentrated in the United States (41% of the world), Western Europe accounted for 30%, Japan accounted for 8%, China's production accounted for only 3.5% of the world's production, but its consumption of 17.5% of the world. Man-made fibers still dominate the production of nonwovens, and the situation will not change significantly before 2007. Worldwide, 63% of the fibers used in nonwovens production are polypropylene, 23% polyester, 8% viscose, 2% acrylic, 1.5% polyamide, and the remaining 3% other fibers. Nonwoven fabrics in the health of absorbent materials, medicine, transportation, footwear with textile materials on the set of the amount of significant growth. Second, nonwoven production and consumption of global nonwoven consumption in 1983 for 800,000 tons, and to 1985 when the growth of 1.1 million tons in 1988 for 1.4 million tons in 1998, the global consumption of nonwovens reached 2.4 million tons, is expected to 2005, its consumption can reach 3.7 million tons. Consumption of man-made fibers used in various textiles was 16.9 million tons in 1983, grew to 20.4 million tons in 1988, reached 30.4 million tons in 1998, and is expected to reach 37 million tons in 2005 and 38.3 million tons in 2007. The growth rate of consumption of man-made fibers in the production of nonwovens is expected to reach 10% by 2005 and 10.4% by 2007. Nonwovens industry consumption growth so fast is partly due to China, Southeast Asia, Latin America and the Middle East, the increase in ancillary industries. Third, non-woven fabrics affect the growth rate of factors all factors affecting the growth of man-made fibers can be more or less to man-made fibers as raw materials for textiles to cause a certain impact, which has the greatest impact on non-woven textiles. Population growth factors have a smaller impact on nonwovens than on other textiles used in apparel. However, population growth is also an important influence if the important use of nonwovens in baby diapers is taken into account. The partial replacement of natural fibers has a greater impact on textiles, but not on nonwovens, which are largely dependent on man-made fibers for their production. The commercial development of man-made fibers and the professional 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. Replacement of textiles and other supplies: this includes replacement by nonwoven textiles, textiles for knitting, plastic films, polyurea foams, wood pulp, leather, etc. This is determined by the cost and performance requirements that the product needs to have. The introduction of new, more economical and efficient production processes: i.e. various articles made from polymers, competitive new nonwoven sets and the introduction of specialty fibers and nonwoven textile additives. The three main fibers used in nonwoven production are polypropylene fibers (62% of the total), polyester fibers (24% of the total) and viscose fibers (8% of the total). Viscose fibers were the most used in nonwovens production between 1970 and 1985, and between 2000 and 2005 the use of polypropylene fibers and polyester fibers began to predominate in hygienic absorbent materials and medical textiles. In the early years of the nonwovens market, the use of nylon was high, and from 1998 the use of acrylic fibers began to rise, especially in the field of artificial leather manufacturing. China's various constructions have a number of large-scale projects, such as the Three Gorges Project, Xiaolangdi Project, environmental protection projects, western development, infrastructure construction and so on, which will greatly promote the consumption of geotextiles, filtration materials, waterproof materials, packaging materials. In addition, the improvement of domestic consumers' income will also strongly stimulate the consumption of a variety of health absorbent products and air filtration materials, medical and health supplies, and labor and sporting goods. Therefore, China's nonwoven industry has great potential for future growth. Main products Nonwoven quilting disposables Medical nonwoven products are medical and health textiles made of chemical fibers including polyester, polyamide, polytetrafluoroethylene (PTFE), polypropylene, carbon fiber and glass fiber. Including disposable masks, protective gowns, surgical gowns, isolation gowns, laboratory gowns, nurses' caps, surgical caps, doctors' caps, surgical kits, maternity kits, first-aid kits, diapers, pillowcases, bedsheets, quilts, shoe covers, and other disposable medical consumables 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 discarded, not only convenient to use, safe and hygienic, but also effective in preventing bacterial infection and medical original *** cross-infection. In China, for medical and health industry investment has reached more than 100 billion yuan, of which the total output value of hygiene products and materials amounted to about 64 billion yuan, and diversified direction. Flour finishing bags Flour bags made of non-woven fabrics, with lightweight, environmentally friendly, moisture-proof, breathable, flexible, flame-retardant, non-toxic, non- ***, recyclable, etc., is internationally recognized as the protection of the earth's ecological environmentally friendly products, is widely used in various types of sets of rice and flour small packages, 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 cleaner than ink printing, fully meet the modern requirements of environmental protection. Due to the reliable quality of the product, the price is affordable and the service life is long. The main specifications are 1 kg, 2.5 kg, 5 kg, 10 kg and other specifications of rice and noodles refined bags, packaging bags, etc.. Fashion shopping bags Non-woven bags (also known as non-woven bags, English: Nonwoven bags) is a green product, tough and durable, beautiful shape, breathable, reusable, washable, silkscreen ads, mark, the use of a long period of time, suitable for any company, any industry as an advertisement, giveaways. Consumers in the shopping at the same time and get a beautiful non-woven bags, and businesses to get the invisible advertising, the best of both worlds, so non-woven in the market is becoming more and more popular. Products to non-woven as raw materials, it is a new generation of environmentally friendly materials, moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic, non- *** sex, colorful, inexpensive, recyclable and so on. The material can be placed in the outdoor 90 days of natural decomposition, placed in the indoor service life of up to 5 years, combustion is non-toxic, tasteless, and no residual material, so as not to pollute the environment, is internationally recognized as the protection of the earth's ecological environmentally friendly products.
