The origin of non-woven fabric

Non-woven fabric, 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, non-toxic and non-irritating, rich in color, and price Low-cost, recyclable and other characteristics. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by a continuous one-step method of high temperature melting, spinning, laying, and hot pressing. It is called cloth because of its appearance and certain properties. The development of the non-woven textile industry 　 　 As of 1998, the world's consumption of non-woven fabrics has reached 2.4 million tons. In 1970, its consumption was only 400,000 tons, and by 2007, its consumption is expected to reach 4 million tons. Manufacturers of non-woven fabrics are mainly concentrated in the United States (41% of the world's total), Western Europe accounted for 30%, Japan accounted for 8%, China's production only accounted for 3.5% of the world's production, and its consumption was 17.5% of the world's .　　Man-made fibers still dominate the production of non-woven fabrics, and this situation will not change much before 2007. 60% of the fibers used in the production of non-woven fabrics worldwide are polypropylene, 23% polyester, 8% viscose, 2% acrylic fiber, 1.5% polyamide, and the remaining 3% other fiber.　　 The application of non-woven fabrics in sanitary absorbent materials, medical, transportation, and shoe-making textile materials has increased significantly.
