Non-woven (English name: Non Woven), also known as non-woven, is directed or random fibers constitute a new generation of environmentally friendly materials, with a moisture-proof, breathable, flexible,
Light, not combustion, easily biodegradable, non-toxic non-irritating, colorful, inexpensive, recyclable and so on. Such as multi-use polypropylene (pp material) granules as raw materials,
High temperature melting, spinning, shop classes, one-step production of continuous hot coiling made. Due to the appearance of a cloth and some performance called cloth.
================================================== ==================
[Concept]
Because it is a weaving and spinning without the formation of fabric, just short of textile fibers or filaments randomly oriented or support columns to form a fiber network structure, and then use machine
Mechanical, thermal or chemical methods such as reinforcement stick together.
It is not a one of the woven yarn, knitting together, but the fiber directly bonded together by physical means, so when you get your clothes in the
Sticky said, they will find, is a root of the thread can not spare the. Break the traditional non-woven fabric of textile works, and has a short process, production speed, high yield, as
The low, wide use, sources of raw materials and more features.
    Because of its appearance shape pearls, also known as pearl canvas.
================================================== ==================
Composition and structure []
     By including non-woven fiber and plant fiber and other chemicals in the water or air as the suspending medium under the conditions in the wet or dry paper-making machine made, although it is in lieu of textile fabric
So called non-woven fabrics. A new generation of environmentally friendly non-woven materials with good strength, breathable waterproof, environmentally friendly, flexible, non-toxic and tasteless, and cost advantages. It is a new generation
Environmentally friendly materials, with a water repellent, breathable, flexible, non-combustion, non-toxic non-irritating, rich colors and so on. If placed outside of the material by the natural decomposition of the longest life expectancy is only
90 days, placed in eight years indoor decomposition, combustion of non-toxic, tasteless, and without any remaining material, so as not to pollute the environment, so the resulting environment.

[Material characteristics]
">
    Non-woven is a non-woven fabric, which is the direct use of polymer chips, staple fiber or filament of fiber into the network through the air or mechanical, then after a spunlace, acupuncture, or hot
Rolling reinforcement, the final after finishing the formation of non-woven fabric. With a soft, breathable and flat structure of the new fiber products, the advantage of not generate lint, tough, durable,
Silky soft, is a kind of reinforcement, but also the feeling of cotton, and cotton compared to non-woven bag is easy to shape, and low cost.
耐久性,一次性。"> durability, one-time. Insulation, non-conductive. Softness, just stiffness. Fine, expansion. Isotropic, anisotropic. Filtration, breathable waterproof.
      Flexible nature of stiffness. Light, loose, warm. Thin as onion skin, thick as felt. Waterproof breathable. Ironing, sewing, molding. Flame retardant, antistatic. Permeable, waterproof,
      Wear, fleece sex. Fold-resistant, flexible, high-moisture, water repellency.
 1 light: polypropylene resin as main raw material, the proportion is only 0.9, and only three-fifths of the cotton, with a fluffy, feel good.
 2 soft: the fine fibers (2-3D) light spots forming hot-melt adhesive. Finished moderate softness, with comfort.
 3 water repellent, breathable: polypropylene slices non-absorbent, zero moisture content, water repellency finished good, from 100% fibers with porosity, air permeability, easy to maintain a dry cloth, easy to
        Washing.
 4 non-toxic, non-irritating: product is in compliance with FDA food-grade raw materials, excluding other chemical composition, stable, non-toxic, no odor, does not irritate the skin.
 5. Antimicrobial, anti-chemicals: Polypropylene is a chemical substance blunt, not moth-eaten, and to isolate bacteria and insects in the presence of liquid erosion; antibacterial and alkaline, not because of product
        Erosion and impact strength.
 6, anti-bacterial. Products with a pull water, not moldy, and isolate the bacteria and insects in the presence of liquid erosion, not mold bore.
 7, good physical properties. Paved network directly from the spinning of polypropylene heat bonded together, staple products, the product is better than the average intensity, intensity non-directional, vertical and horizontal intensity similar.
 8, the environment, the majority of currently used non-woven material is polypropylene, and plastic raw material is polyethylene, although the names of the two substances are similar, but
        Chemical structure is very different. The molecular structure of polyethylene has a very strong chemical stability, extremely difficult to degrade, so the plastic bag takes 300 years to decompose completed;
        The chemical structure of polypropylene is not solid, the molecular chain can easily be broken, which can effectively degrade and non-toxic form in the next step in the environmental cycle,
        A non-woven shopping bags within 90 days, you can completely break down. And non-woven shopping bags can be reused 10 times or more, waste pollution on the environment after only plastic
        Liaodai 10%

 1) compared with the strength and durability of textile fabrics poor
 2) can not be as clean as other fabrics
 3) fibers arranged in a certain direction, at right angles to the direction from the crack so easily and so on. Therefore, the recent improvement of production methods on the prevention of major improvements on the split.
================================================== ==================
[Category] (according to the different production process)
Mainly non-woven polypropylene fiber production (PP), polyester (PET). In addition, polyamide (PA), viscose, acrylic, Polyethylene (HDPE), polyvinyl chloride (PVC).
According to application requirements, woven into a one-time application-oriented and durable two categories.
 1, spunlace non-woven fabrics:
            Spunlace process is the high-pressure water jet micro-fiber line to one or more layers, the fibers intertwined with each other, so that the fiber network to be reinforced and have a certain strength.
 2, non-woven heat:
            Thermally bonded non-woven fiber web is in fibrous or powder added to hot melt adhesive reinforcement, fiber network and then cooling the heated melt into the fabric reinforcement.
 3, pulp airlaid non-woven fabrics:
            Can be called airlaid non-woven wipes, dry paper cloth. It is the use of airlaid wood pulp fiber technology will open the loose fibers into a single state, then
            Flow method using the fiber aggregation into the network in the curtain, the fiber network and then into the fabric reinforcement.
 4, wet non-woven fabrics:
            Wet non-woven is placed in the water medium fiber raw materials into a single fiber opening song, while mixing different fiber material, made from pulp fiber suspension, suspended slurry transport
            To form a network organization, fiber in the wet state into a network and then into the fabric reinforcement.
 5, spunbond nonwoven:
            Spunbond non-woven fabrics in the polymer has been extruded to form a continuous filament stretch, the filament laying into the net, and then through its own fiber network bonding, thermal bonding, chemical adhesive
            Together or mechanical reinforcement methods to become a non-woven fiber web.
 6, melt-blown non-woven fabrics:
            Meltblown nonwoven process: polymer melt extrusion feed --- --- --- fibers formed into a network of fiber cooling --- --- reinforcement into cloth.
 7, acupuncture nonwovens:
            Non-woven needle is a dry non-woven, non-woven is the use of acupuncture needles to puncture the role of the fluffy fiber web reinforcement into cloth.
 8, non-woven stitch:
            Stitch non-woven is a dry non-woven, stitch method is to use the warp coil structure of the fiber network, yarn layer, non-textile materials (such as plastic sheets,
            Plastic thin metal foil, etc.) or their combination for reinforcement, as material for producing nonwoven fabric.
