Non-woven fabric has no warp and weft, cutting and sewing are very convenient, and light and easy to shape, deeply loved by manual enthusiasts. This is because it is a kind of fabric that does not need spinning and weaving. It is just oriented or randomly arranged textile short fibers or long filaments to form a fiber network structure, and then reinforced by mechanical, thermal adhesive or chemical methods. Instead of being interwoven and braided one by one, the fibers are physically glued together, so that when you reach the scale in your clothes, you will find that you cannot pull out the threads. Nonwovens break through the traditional textile principle, and has a short process and fast production rate. It has the following characteristics 1. Light weight: With polypropylene resin as the main raw material, the proportion is only 0.9, only three-fifths of cotton, fluffy, good hand feel. 2. Soft: composed of fine fibers (2-3D) light hot melt bonding molding. The finished product has moderate softness and comfortable feeling. 3. dial water, breathable: polypropylene slice does not absorb water, water content is zero, the finished product is good water, composed of pure fiber porous, good air permeability, easy to keep the cloth dry, easy to wash. 4. Non-toxic and non-irritating: The product is made of food grade raw materials conforming to FDA, without other chemical components, stable performance, non-toxic, no odor, no skin irritation. 5. Antibacterial and anti-chemical agents: polypropylene is a chemical blunt substance, not moth eaten, and can isolate the erosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion, finished products do not affect the strength due to erosion. 6, antibacterial. The products are drawn water, no mold, and can isolate the erosion of bacteria and insects in the liquid, no mold. 7, good physical property. By polypropylene spinning directly spread into a mesh of hot bonding, product strength is better than the general staple fiber products, strength is non-directional, vertical and horizontal strength is similar.
8.In terms of environmental protection, the raw material of most non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the two substances have similar names, they are far apart in their chemical structure. The chemical and molecular structure of polyethylene is very stable and difficult to degrade, so it takes 300 years for plastic bags to decompose. Polypropylene, on the other hand, has a weak chemical structure and its molecular chains can be easily broken, which allows it to degrade effectively and enter the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed in 90 days. Non-woven shopping bags can be reused more than 10 times, and their pollution to the environment is only 10 percent of that of plastic bags.
