What are the advantages of non woven cloth?

Advantages of non woven materials

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 meals grade raw materials in accordance with FDA, without other 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 just isn’t insect-eaten and may isolate the erosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion, completed 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 power of the products is better than the overall staple fiber products, the energy of the directionless, just like the vertical and horizontal strength.

5. In terms of environmental protection, polypropylene is the raw material of most non woven fabrics, while polyethylene is the raw material of plastic bags. Though the 2 substances have related names, they’re quite totally different in chemical structure. The chemical molecular construction of polyethylene has quite sturdy 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 might be easily broken, so that it may be successfully degraded, and it enters the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within ninety days. Moreover, the non-woven shopping bags could be reused for more than 10 instances, and the pollution to the setting 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, in order that the fibers are entangled with each other, in order that the fiber network will be strengthened and have a certain strength.

2. Heat-bonded non woven material

Thermal bonding non woven material refers to the addition of fiber mesh or powder hot soften bonding reinforcement materials, fiber mesh after heating melting cooling reinforcement into cloth.

3. The pulp flows into a net of non-woven material

The air flow into the net non-woven cloth will 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 into a single fiber state, and then use air circulation method to make the fiber agglutination within the net curtain, fiber mesh reinforcement into cloth.

4. Wet non woven cloth

Wet non-woven fabric is the fiber raw material within the water medium is opened right into a single fiber, on the identical time, completely different fiber raw supplies are mixed, made into fiber suspension slurry, suspension slurry is transported to the network forming mechanism, the fiber within the wet state right into a network and then strengthened into cloth.

5. Spunbonded, non woven fabric

Spunbonded non-woven material is in the polymer has been extruded, stretch and form a steady filament, filament laid 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

Soften-blown non-woven process: polymer feeding – soften extrusion – fiber formation – cooling – right into a network – reinforcement into cloth.

7. Acupuncture on non woven material

Needling non-woven material is a kind of non-woven material by dry method. Needling non-woven cloth is to strengthen the fabric with a fluffy fiber net by using the puncture perform of needles.

8. Stitch non woven fabric

non woven material is a kind of dry non woven fabric. The knitting method is to make use of the warp knitting coil structure to reinforce the fiber mesh, yarn layer, non-textile material (akin to plastic sheet, plastic thin metal foil, etc.) or their mixture to make non woven fabric.
