What are the advantages of non woven fabric?

 

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-toxic and non-irritating: the product is manufactured with meals grade raw materials in accordance with FDA, without different chemical ingredients, stable performance, non-poisonous, 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 might isolate the erosion of micro organism and insects in the liquid; Antibacterial, alkali corrosion, completed products do not affect the power attributable to 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 strength of the directionless, similar to 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 are quite different in chemical structure. The chemical molecular structure of polyethylene has quite strong stability and is extraordinarily difficult to degrade, so it takes 300 years for plastic bags to decompose. The chemical structure of polypropylene is weak, and the molecular chain will be simply broken, in order that it could be effectively degraded, and it enters the following environmental cycle in a non-toxic 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 occasions, and the air pollution to the surroundings 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, in order that the fiber network could be strengthened and have a sure strength.

 

 

 

 

2. Heat-bonded non woven fabric

 

 

 

 

Thermal bonding non woven material refers 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 cloth

 

 

 

 

The air movement into the net non-woven cloth may also be called mud-free paper, dry paper making non-woven cloth. It's the usage of air mesh technology to open the wood pulp fiber board loose right into a single fiber state, after which use air circulate technique to make the fiber agglutination in the net curtain, fiber mesh reinforcement into cloth.

 

 

 

 

4. Wet non woven material

 

 

 

 

Wet non-woven fabric is the fiber raw materials in the water medium is opened right into a single fiber, on the identical time, totally 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 and then strengthened into cloth.

 

 

 

 

5. Spunbonded, non woven material

 

 

 

 

Spunbonded non-woven fabric is within the polymer has been extruded, stretch and type 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. Melt spray non woven material

 

 

 

 

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

 

 

 

 

7. Acupuncture on non woven cloth

 

 

 

 

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

 

 

 

 

8. Stitch non woven cloth

 

 

 

 

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