Non woven fabric (also known as non-woven fabric) is a new generation of environmentally friendly materials, which has the characteristics of water repellent, breathable, flexible, non combustible, non-toxic and non irritating, and rich colors. If this material is placed outdoors and naturally decomposed, its longest lifespan is only 90 days. If placed indoors, it decomposes within 5 years, and when burned, it is non-toxic, odorless, and has no residual substances, thus not polluting the environment. Therefore, environmental protection comes from this. Suitable for washing and other items.
It is a new type of fiber product with soft, breathable, and flat structure formed directly using polymer slices, short fibers, or long fibers through various web forming methods and consolidation techniques.
1. Lightweight: Using polypropylene resin as the main production material, with a specific gravity of only 0.9, only three fifths of cotton, it has fluffiness and a good hand feel.
2. Soft: Composed of fine fibers (2-3D), it is formed by light spot hot melt bonding. The finished product has moderate softness and a comfortable feeling.
3. Water repellent and breathable: Polypropylene slices do not absorb water and have zero moisture content. The finished product has good water repellent properties and is composed of 100% fibers, which are porous and breathable, making it easy to keep the fabric dry and easy to wash.
4. Non toxic and non irritating: The product is produced using FDA food grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, odorless, and does not irritate the skin.
5. Antibacterial and chemical resistant agents: Polypropylene is a chemically inert substance that is not insect infested and can isolate the erosion of bacteria and insects in liquids; Antibacterial, alkaline corrosion, and the strength of the finished product is not affected by erosion.
6. Antibacterial properties. The product is water-resistant, does not mold, and can isolate the erosion of bacteria and insects in the liquid, without mold damage.
7. Good physical properties. Made by spinning polypropylene and directly laying it into a mesh through thermal bonding, the product has better strength than ordinary short fiber products, with no directional strength and similar longitudinal and transverse strength.
8. In terms of environmental protection, the majority of non-woven fabrics currently used are made of polypropylene, while plastic bags are made of polyethylene. Although the two substances have similar names, their chemical structures are vastly different. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so plastic bags need 300 years to decompose completely; However, the chemical structure of polypropylene is not strong, and the molecular chains can easily break, which can effectively degrade and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and their environmental pollution after disposal is only 10% of that of plastic bags.
