Advantages and disadvantages of non-woven fabrics（2）
3. Water repellency and air permeability: Polypropylene slices do not absorb water, have zero elongation, and have good water repellency. It is composed of 100% fiber and has good air permeability. It is easy to keep the cloth dry and easy to wash.
4. Non-toxic, non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, has no peculiar smell, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically dense substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, the strength of the finished product will not be affected by erosion.
6. Antibacterial. The product is water-repellent, non-mold, and can isolate the erosion of bacteria and insects in the liquid without mold.
7. Good physical properties. Directly spread into a net by polypropylene spinning and thermoforming, the product strength is better than ordinary staple fiber products, the strength is non-directional, and the vertical and horizontal strengths are similar.
8. In terms of environmental protection, the raw material of most of the non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And non-toxic and non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.
Disadvantages:
1) The ratio of strength and sustainability to textile fabrics is poor.
2) Cannot be washed like other fabrics.
3) The fibers are separated in a certain direction, so it is easy to split from the right angle direction and so on. Therefore, the improvement of the production method mainly focuses on the improvement of preventing splitting.
