What are the advantages of non woven material?

 

Advantages of non woven materials

 

 

 

Advantages:

 

 

 

 

1. Light weight: with polypropylene resin as the primary raw material, 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 meals 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 can isolate the erosion of micro organism and insects within the liquid; Antibacterial, alkali corrosion, completed products don't affect the power attributable to erosion.

 

 

 

 

4. Good physical properties. Made of polypropylene spinning directly right into a net of thermal bonding products, the strength of the products is best than the general staple fiber products, the energy 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 materials of plastic bags. Although the 2 substances have related names, they are quite different in chemical structure. The chemical molecular construction of polyethylene has quite sturdy stability and is extraordinarily tough 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 easily broken, in order that it could be successfully degraded, and it enters the following environmental cycle in a non-toxic form. A non-woven shopping bag will be completely decomposed within 90 days. Moreover, the non-woven shopping bags will be reused for more than 10 times, and the air 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, so that the fiber network could be strengthened and have a sure strength.

 

 

 

 

2. Heat-bonded non woven material

 

 

 

 

Thermal bonding non woven fabric refers to the addition of fiber mesh or powder scorching melt bonding reinforcement supplies, fiber mesh after heating melting cooling reinforcement into cloth.

 

 

 

 

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

 

 

 

 

The air move into the net non-woven material can also be called dust-free paper, dry paper making non-woven cloth. It is the usage of air mesh technology to open the wood pulp fiber board loose into a single fiber state, after which use air circulation technique to make the fiber agglutination in the net curtain, fiber mesh reinforcement into cloth.

 

 

 

 

4. Wet non woven material

 

 

 

 

Wet non-woven material is the fiber raw material within the water medium is opened into a single fiber, at the similar time, totally different fiber raw supplies are combined, made into fiber suspension slurry, suspension slurry is transported to the network forming mechanism, the fiber within the wet state into a network and then strengthened into cloth.

 

 

 

 

5. Spunbonded, non woven cloth

 

 

 

 

Spunbonded non-woven fabric is within the polymer has been extruded, stretch and type a continuous filament, filament laid right into a network, fiber network after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement technique, so that the fiber network into non-woven cloth.

 

 

 

 

6. Melt spray non woven fabric

 

 

 

 

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

 

 

 

 

7. Acupuncture on non woven cloth

 

 

 

 

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

 

 

 

 

8. Stitch non woven material

 

 

 

 

non woven cloth is a kind of dry non woven fabric. The knitting technique is to make use of the warp knitting coil construction to bolster the fiber mesh, yarn layer, non-textile materials (equivalent to plastic sheet, plastic thin metal foil, etc.) or their mixture to make non woven fabric.
