The concept and characteristics of non-woven fabrics


Non woven fabric (also known as non-woven fabric) is a new generation of environmentally friendly materials, with characteristics such as water repellency, breathability, flexibility, non combustible, non-toxic and non irritating, and rich colors. If the material is placed outdoors and naturally decomposed, its maximum lifespan is only 90 days. If it is placed indoors and decomposed within 5 years, it is non-toxic, odorless, and has no residual substances when burned, 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, which is directly formed through various fiber mesh forming methods and consolidation techniques using high polymer slicing, short fibers, or long filaments.
1. Lightweight: Made mainly from polypropylene resin, with a specific gravity of only 0.9, which is only three-fifths of cotton. It has fluffiness and a good hand feel.
2. Soft: Made 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 absorption and breathability: Polypropylene chips do not absorb water, have zero moisture content, and the finished product has good water absorption performance. It is composed of 100% fibers with porosity and good breathability, making it easy to keep the fabric surface dry and easy to wash.
4. Non toxic and non irritating: The product is produced using FDA compliant food grade raw materials, free of other chemical components, stable in performance, non-toxic, odorless, and non irritating to the skin.
5. Antibacterial and anti chemical agents: Polypropylene is a chemically inert substance that does not cause insect infestation and can isolate bacteria and insects present in the liquid; Antibacterial, alkaline corrosion, and the strength of the finished product is not affected by erosion.
6. Antibacterial properties. The product has water repellency, is not moldy, and can isolate the erosion of bacteria and insects in the liquid, without mold and decay.
7. Good physical properties. Made by directly laying polypropylene spinning into a mesh and hot bonding, the product has better strength than general short fiber products, with no directional strength and similar longitudinal and transverse strength.
In terms of environmental protection, the majority of non-woven fabrics currently used are made of polypropylene, while the raw material for plastic bags is 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 take 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 the pollution level to the environment after disposal is only 10% of that of plastic bags.
