What are the advantages and disadvantages of non-woven fabrics and its performance purposes?
Time:2016-12-20
Non-woven fabric without latitude and longitude, tailoring and sewing are very convenient, and lightweight easy stereotypes, loved by the manual enthusiasts.
Because it is a kind of form that does not require spinning weaving fabric, but the textile fiber or filament for directional or random support, the formation of the fiber network structure, and then the mechanical, thermal or chemical methods and strengthening into.
It is not by interleaving, a yarn knitting together, but the fibers directly through physical methods together, so, when you get your clothes stick said, you will find that is not a root of the thread. The nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short technological process, fast production rate, high output, low cost, wide application and many sources of raw materials.

The relationship between spunbonded fabric and non-woven fabrics and nonwovens is subordination. There are many manufacturing non-woven fabric production process, which is a kind of spunbonded non-woven spunbonded non-woven fabric production process (including the spunbond, melt blown, hot rolling method, water jetting method, now on the market are mostly used in the production of non-woven spunbond)
Spunbonded nonwoven fabric
According to the composition of non-woven polyester, polypropylene, nylon, spandex, acrylic, etc.; different components have different styles of non-woven fabric. The nonwovens, usually refers to the spunbonded polyester, polypropylene spunbonded; and the two cloth style is very close, through high temperature test in order to distinguish.
The composition and structure of non-woven products, rich colors, bright and lively fashion, environmental protection, wide use, beautiful appearance, patterns and styles are diverse, and light quality, environmental protection, can be recycled, is internationally recognized for the protection of the earth's ecological environmental protection product. Suitable for agricultural films, footwear, leather, composite, mattress, decoration, printing, chemical, automobile, building materials, furniture and other industries, and interlining, medical disposable surgical gowns, masks, hats, bed sheets, disposable tablecloth, hotel beauty, gift bags, fashion boutique sauna and even today when the bag, shopping bag advertising bag, etc.. Environmental protection products, widely used, affordable.
Non woven fabric
Non-woven because of its appearance similar to the Pearl, also known as the Pearl canvas.
The non-woven fabric including chemical fiber and plant fiber in air or water as the suspension medium under the condition of wet or dry paper machine made of cloth, although without the term for non-woven textile. Non-woven fabric is a new generation of environmentally friendly materials, with strong, breathable waterproof, environmentally friendly, flexible, non-toxic tasteless, and cheap and other advantages. It is a new generation of environmentally friendly materials, has the characteristics of waterproof, breathable, flexible, non combustion, non-toxic non irritating, rich color etc.. If the material is placed outside the natural decomposition, the longest life span of only 90 days, under 8 years of indoor decomposition, combustion of non-toxic, tasteless, and without any remaining material, so as not to pollute the environment, and therefore the resulting environmental.

Material characteristics non-woven properties
Non woven fabric is a nonwoven fabric, it is the direct use of polymer slice, short fiber or filament fiber through air or machinery into a network, and then through the spunlaced, acupuncture, or hot rolling reinforcement, non woven fabric after finishing forming. New fiber products with soft, breathable and a flat structure, has the advantages of no fiber, tough and durable, silky soft, but also enhance a material, but also cotton feeling, compared with cotton, non-woven bags and easy forming, low cost.
Material characteristics:
1 light weight: polypropylene resin as the main raw material production, the proportion of only 0.9, only cotton of the 3/5, fluffy, feel good.
2 soft: composed of fine fiber (2-3D) with hot melt adhesive forming. Finished softness moderate, comfortable.
3 sets of water, breathable polypropylene chip: no water absorption, moisture content of zero, finished water repellency, consisting of 100% fibers with porous, good air permeability, easy to maintain, easy to wash and dry cloth.
4 non-toxic, non irritating: the product uses in line with FDA food grade raw material production, does not contain other chemical composition, stable performance, non-toxic, no peculiar smell, does not stimulate the skin.
5 antibacterial, anti chemical: polypropylene is blunt chemical substances, not insects, and can exist in isolation liquid bacteria and insects erosion; antibacterial, corrosion, erosion and impact strength for the product.
6 antibacterial property. Pull out water products, not moldy, and isolation of bacteria and insects are liquid erosion, no mildew and moth.
7 good physical properties. By direct spinning PP paved net heat bonding, product strength than ordinary staple products is preferred, non directional strength, transverse strength is similar.
8 in terms of environmental protection, most of the non-woven fabric is currently used polypropylene raw materials, and plastic bags of raw materials are polyethylene, although the two substances similar names, but in the chemical structure is far. The chemical molecular structure of polyethylene has very strong stability, extremely difficult to degrade, so the plastic bag needs 300 years before the completion of the decomposition; chemical structure of polypropylene is not solid, the molecular chain is easily broken, which can be effectively degraded, and enter the environmental cycle the next step in a non-toxic form. Non-woven shopping bags in 90 days can be completely decomposed. And non-woven shopping bags can be reused more than 10 times, the waste pollution of the environment is only 10% plastic bags, wallets hardware
