PP non-woven advantages: 1). Light: polypropylene resin as the main raw material, the proportion is only 0.9, only cotton three-fifths, with a fluffy, feel good. 2). Soft: from fine fibers, tap hot-melt adhesive molding. Finished softness moderate, with comfort. 3). Water-repellent, breathable: Polypropylene slice does not absorb water, moisture content zero, finished good water repellency, made from 100% fibers with porosity, permeability good, easy to maintain the fabric dry, easy to wash. 4). Non-toxic, non-irritating: The products comply with FDA food-grade raw materials, without other chemical composition, stable, non-toxic, no smell, does not irritate the skin. 5). Antibacterial, anti-chemical: Polypropylene is blunt chemical substances, no insects, and can isolate bacteria and insects presence of liquid erosion; Antibacterial, alkali corrosion, erosion and the finished product does not affect the strength due. 6). Physical resistance. Spinning from polypropylene thermally bonded together directly paved network, product strength is better than the average staple products, non-directional strength, longitudinal and transverse strength similar. 7). On the environment, currently used by most non-woven material is polypropylene, and plastic raw materials are polyethylene, two substances although the name is similar, but in the chemical structure is very different. Polyethylene chemical molecular structure has a very strong stability, extremely difficult to degrade, so the bags to 300 years to decompose completed; the polypropylene chemical structure is not solid, the molecular chains can easily be broken, which can effectively degrade , and in the non-toxic form in the next step the environmental cycle, a non-woven shopping bags in 90 days can be completely decomposed. And woven shopping bags can be reused more than 10 times, after disposal of the environment pollution, only plastic bags by 10%.
