Advantages of non woven fabrics
Advantages:
1. Light weight: with polypropylene resin as the principle raw material, the proportion is only 0.9, only three-fifths of that of cotton, with fleeciness and good feel.
2. Non-poisonous and non-irritating: the product is manufactured with food grade raw supplies in accordance with FDA, without other chemical ingredients, stable efficiency, non-poisonous, odorless and non-irritating to skin.
3. Antibacterial and anti-chemical agents: polypropylene is a chemically blunt substance, which isn’t insect-eaten and may isolate the erosion of bacteria and insects within the liquid; Antibacterial, alkali corrosion, finished products don’t have an effect on the power because of erosion.
4. Good physical properties. Made of polypropylene spinning directly into a net of thermal bonding products, the energy of the products is better than the overall staple fiber products, the power of the directionless, just like the vertical and horizontal strength.
5. By way of environmental protection, polypropylene is the raw material of most non woven materials, while polyethylene is the raw material of plastic bags. Although the two substances have related names, they’re quite completely different in chemical structure. The chemical molecular structure of polyethylene has quite robust stability and is extraordinarily troublesome to degrade, so it takes 300 years for plastic bags to decompose. The chemical structure of polypropylene is weak, and the molecular chain can be easily broken, so that it might be effectively degraded, and it enters the following environmental cycle in a non-poisonous form. A non-woven shopping bag will be fully decomposed within 90 days. Moreover, the non-woven shopping bags will be reused for more than 10 times, and the air pollution to the atmosphere after being discarded is only 10% of that of plastic bags.
Classification of non woven materials
1. Spiny non woven fabric
The spining process is to spray a high pressure water jet onto one or more layers of fiber network, so that the fibers are entangled with one another, so that the fiber network could be strengthened and have a sure strength.
2. Heat-bonded non woven cloth
Thermal bonding non woven fabric refers back to the addition of fiber mesh or powder scorching soften bonding reinforcement supplies, fiber mesh after heating melting cooling reinforcement into cloth.
3. The pulp flows into a net of non-woven fabric
The air movement into the net non-woven material can also be called dust-free paper, dry paper making non-woven cloth. It’s the usage of air mesh technology to open the wood pulp fiber board loose into a single fiber state, after which use air circulate method to make the fiber agglutination in the net curtain, fiber mesh reinforcement into cloth.
4. Wet non woven material
Wet non-woven cloth is the fiber raw materials within the water medium is opened into a single fiber, at the similar time, totally different fiber raw materials are mixed, made into fiber suspension slurry, suspension slurry is transported to the network forming mechanism, the fiber within the wet state into a network after which strengthened into cloth.
5. Spunbonded, non woven fabric
Spunbonded non-woven material is in the polymer has been extruded, stretch and kind a steady filament, filament laid into a network, fiber network after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement methodology, in order that the fiber network into non-woven cloth.
6. Soften spray non woven material
Soften-blown non-woven process: polymer feeding – soften extrusion – fiber formation – cooling – into a network – reinforcement into cloth.
7. Acupuncture on non woven cloth
Needling non-woven cloth is a kind of non-woven fabric by dry method. Needling non-woven cloth is to bolster the cloth with a fluffy fiber net by using the puncture perform of needles.
8. Stitch non woven material
non woven fabric is a kind of dry non woven fabric. The knitting method is to make use of the warp knitting coil construction to bolster the fiber mesh, yarn layer, non-textile materials (corresponding to plastic sheet, plastic thin metal foil, etc.) or their mixture to make non woven fabric.
