advantage:
1. Lightweight: Polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, and only cotton
Finished non-woven fabric
Finished non-woven fabric (4 sheets)
Three-fifths, fluffy and feel good.
2. Soft: It is composed of fine fibers (2-3D) and is formed by light-point hot-melt bonding. The finished product is moderately soft and comfortable.
3. Water-repellent and breathable: Polypropylene slices do not absorb water, have zero water content, and have good water-repellent properties. They are made of 100% fiber and are porous and air-permeable. 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, is non-toxic, non-odor, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, which is not moth-eaten, and can isolate the corrosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and the strength of the finished product will not be affected by erosion.
6. Antibacterial. The product is water-repellent, does not mold, 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 spun yarn directly spread into a net and thermally bonded. 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 non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, the chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to decompose, 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 enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution to the environment after being discarded is only 10% of that of the plastic bag.



shortcoming:
1) Compared with woven cloth, the strength and durability are poor.
2) 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 direction and so on. Therefore, the improvement of the production method mainly focuses on the improvement of preventing splitting.
