Disadvantages And Advantages Of Non-woven Fabrics

advantage:

1. Lightweight: Polypropylene resin is the main raw material for production, with a specific gravity of only 0.9 and only three-fifths of cotton. It is fluffy and feels good.

2. Softness: Composed of fine fibers (2-3D), light spot-like hot-melt bonding. The finished product is moderately soft and comfortable.

3. Water repellent and breathable: polypropylene chips are non-absorbent and have zero moisture content. The finished product has good water repellent. It is composed of 100% fiber with porosity and good permeability. It is easy to keep the cloth dry and easy to wash.

4. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical ingredients, has stable performance, non-toxic, no odor, and does not irritate the skin.

5. Antibacterial and anti-chemical agents: Polypropylene is a chemically inactive substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion.

6. Antibacterial. The product is water-removing, not moldy, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.

7. Good physical properties. It is made of polypropylene spinning directly laid into a mesh and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional and the strength in the vertical and horizontal directions is similar.

8. In terms of environmental protection, the raw material used for most non-woven fabrics is polypropylene, and the raw material for plastic bags is polyethylene. Although the two substances have similar names, they are far from each other in chemical structure. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade, so the plastic bag takes 300 years to decompose; and the chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, which can be effectively degraded And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the environmental pollution after disposal is only 10% of the plastic bags.

Disadvantages:

1) Compared with woven cloth, the strength and durability are poor.

2) It cannot be cleaned like other fabrics.

3) The fibers are arranged in a certain direction, so it is easy to split from the right angle and so on. Therefore, the improvement of production methods is mainly placed on the improvement of preventing division.
