Material characteristics Non-woven fabric characteristics

Material characteristics Non-woven fabric characteristics Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical netting, and then undergoes spunlacing, needle punching, or hot rolling A non-woven fabric formed by reinforcement and finishing. A new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it has a cotton feel. Compared with cotton, non-woven The cloth bag is easy to form and cheap to manufacture.　　Material characteristics: 　　1. Lightweight: Polypropylene resin is used as the main raw material for production. The specific gravity is only 0.9, which is only three-fifths of cotton. It is fluffy and feels 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 moisture 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, non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical components, 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, 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, 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 yarn and directly spread into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products.
