What are the characteristics and advantages of non-woven fabrics
Non-woven fabric is a kind of non-woven fabric, which directly uses high polymer chips, short fibers or filaments to form fibers through air flow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally Finished non-woven fabric. A new type of fiber product with a soft, breathable and flat structure, the advantage is that it does not produce lint, is strong, durable, silky soft, and is also a kind of reinforcing material, and also has a cotton feel. Compared with cotton fabrics, non-woven Cloth bags are easy to form and inexpensive to manufacture.
Features of non-woven fabrics: Durability, Disposable. Insulating, non-conducting. Softness, stiffness. fineness, expansion. Isotropic, anisotropic. Filterability, breathable and impermeable. Elasticity, stiffness. Light, relaxed, warm. Thin as cicada wings, thick as felt. Waterproof and breathable. Ironing, sewing, moulding. Flame retardant, antistatic. Water-permeable, waterproof, wear-resistant, fleece. Wrinkle resistance, good elasticity, high moisture absorption, water repellency.
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. Softness: 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 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.
4. Non-toxic and non-irritating: the product is produced with FDA food-grade raw materials, without other chemical ingredients, stable performance, non-toxic, no peculiar smell, and does not irritate the skin.
5. Antibacterial and anti-chemical agents: Polypropylene is a chemically passive substance, not moth-eaten, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion.
6. Antibacterial properties. 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, Wenzhou Xinyu Non-woven Fabric Co., LTD. said that the raw material of most non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Similar, but very different in chemical structure. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade, so it takes 300 years for plastic bags to decompose. The chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, which can be effectively degraded, and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. In addition, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after disposal is only 10% of that of the plastic bag
