It is called non-woven fabric because of its appearance and certain properties of cloth.
1. Light weight: polypropylene resin is used as the main raw material for production, with a specific gravity of only 0.9, only three-fifths of cotton, with fluffy and good hand feeling.
2. Soft: It is composed of fine fibers (2-3D) and is formed by light point-like hot melt bonding. The finished product is moderately soft and comfortable.
3. Water repellency and breathability: polypropylene chips do not absorb water, have zero moisture content, and the finished product has good water repellency. It is composed of 100% fiber, which is porous and has good air permeability. It is easy to keep the cloth surface dry and easy to wash. .

6. Antibacterial property: The product is water-repellent, 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 spun directly into a mesh and thermally bonded. The strength of the product is better than that of the general staple fiber product, 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 currently used is polypropylene, and a non-woven shopping bag can be completely decomposed within 90 days.
