Advantages of non woven materials
Advantages:
1. Light weight: with polypropylene resin as the principle raw materials, the proportion is only 0.9, only three-fifths of that of cotton, with fleeciness and good feel.
2. Non-toxic and non-irritating: the product is manufactured with food grade raw materials in accordance with FDA, without different chemical ingredients, stable performance, non-toxic, odorless and non-irritating to skin.
3. Antibacterial and anti-chemical agents: polypropylene is a chemically blunt substance, which shouldn’t be insect-eaten and may isolate the erosion of bacteria and bugs within the liquid; Antibacterial, alkali corrosion, finished products do not have an effect on the power resulting from erosion.
4. Good physical properties. Made of polypropylene spinning directly right into a net of thermal bonding products, the strength of the products is better than the final staple fiber products, the energy of the directionless, similar to the vertical and horizontal strength.
5. In terms of environmental protection, polypropylene is the raw materials of most non woven fabrics, while polyethylene is the raw material of plastic bags. Though the two substances have related names, they are quite different in chemical structure. The chemical molecular structure of polyethylene has quite strong stability and is extraordinarily troublesome to degrade, so it takes 300 years for plastic bags to decompose. The chemical construction of polypropylene is weak, and the molecular chain may be simply broken, so that it may be effectively degraded, and it enters the following environmental cycle in a non-toxic form. A non-woven shopping bag can be fully decomposed within ninety days. Moreover, the non-woven shopping bags can be reused for more than 10 times, and the pollution to the environment after being discarded is only 10% of that of plastic bags.
Classification of non woven materials
1. Spiny non woven material
The spining process is to spray a high pressure water jet onto one or more layers of fiber network, in order that the fibers are entangled with each other, so that the fiber network could be strengthened and have a certain strength.
2. Heat-bonded non woven cloth
Thermal bonding non woven material refers back to the addition of fiber mesh or powder sizzling melt bonding reinforcement supplies, fiber mesh after heating melting cooling reinforcement into cloth.
3. The pulp flows right into a net of non-woven fabric
The air flow into the net non-woven cloth can also be called mud-free paper, dry paper making non-woven cloth. It is using air mesh technology to open the wood pulp fiber board loose right into a single fiber state, and then use air circulate methodology to make the fiber agglutination in the net curtain, fiber mesh reinforcement into cloth.
4. Wet non woven cloth
Wet non-woven fabric is the fiber raw materials within the water medium is opened right into a single fiber, on the similar time, completely different fiber raw materials are combined, made into fiber suspension slurry, suspension slurry is transported to the network forming mechanism, the fiber in the wet state right into a network after which strengthened into cloth.
5. Spunbonded, non woven material
Spunbonded non-woven cloth is within the polymer has been extruded, stretch and type a steady filament, filament laid right into a network, fiber network after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement method, so that the fiber network into non-woven cloth.
6. Soften spray non woven material
Melt-blown non-woven process: polymer feeding – melt extrusion – fiber formation – cooling – right into a network – reinforcement into cloth.
7. Acupuncture on non woven fabric
Needling non-woven cloth is a kind of non-woven cloth by dry method. Needling non-woven material is to reinforce the fabric with a fluffy fiber net through the use of the puncture perform of needles.
8. Stitch non woven cloth
non woven fabric is a kind of dry non woven fabric. The knitting methodology is to make use of the warp knitting coil construction to reinforce the fiber mesh, yarn layer, non-textile materials (akin to plastic sheet, plastic thin metal foil, etc.) or their combination to make non woven fabric.
