Basic introduction of non-woven fabrics
Overview Non-woven fabric (English name: Non Woven), also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It is moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, and non-toxic. Non-irritating, rich in color, low in price, recyclable and so on. For example, polypropylene (pp material) pellets are used as raw materials, and are produced by a continuous one-step method of high temperature melting, spinning, laying, and hot pressing and coiling. It is called cloth because of its appearance and certain properties.
The producers of non-woven fabrics are mainly concentrated in the United States (41% of the world), Western Europe accounts for 30%, Japan accounts for 8%, China's production only accounts for 3.5% of the world's production, but its consumption is 17.5% of the world's . It is estimated that by 2007, China's production will reach 7% of the world's production, and its consumption will increase to 21% of the world's.
At present, man-made fibers still dominate the production of nonwovens, and before 2007, this situation will not change significantly. 63% of the fibers used in the production of nonwovens worldwide are polypropylene, 23% polyester, 8% viscose, 2% acrylic, 1.5% polyamide and the remaining 3% are others fiber.
Features introduction
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 after finishing Formed non-woven fabric. A new type of fiber product with a soft, breathable and flat structure, the advantages are that it does not produce lint, is strong, durable, silky soft, and has a cotton feel. Compared with cotton fabrics, non-woven bags are easy to form, and Cheap.
In terms of environmental protection, the raw material of most of the 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 quite different in chemical structure. The chemical molecular structure of polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so it 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. And non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after disposal is only 10% of that of plastic bags.
