Non woven fabric is composed of directional or random fibers. It is a new generation of environmental protection materials, which is moisture-proof, breathable, flexible, light, non combustion supporting, easy to decompose, non-toxic and non irritating, rich in color, low in price, recyclable, etc. For example, polypropylene (pp material) granules are mostly used as raw materials, which are produced by continuous one-step process of high temperature melting, spinning, laying, hot pressing and coiling. It is called cloth because of its appearance and some properties.
At present, man-made fibers still dominate the production of non-woven fabrics, and this situation will not change significantly until 2007. 63% of the fibers used in non-woven fabric production worldwide are polypropylene, 23% are polyester, 8% are viscose, 2% are acrylic fiber, 1.5% are polyamide, and the remaining 3% are other fibers.
In recent years, the application of non-woven fabrics in sanitary absorption materials, medical materials, transportation vehicles, and footwear textile materials has increased significantly.
The commercial development of man-made fibers and the professional application of non-woven fabrics: Due to the establishment of international economic treaties, the trade of microfibers, composite fibers, biodegradable fibers and new types of polyester fibers has grown. This has a great impact on non-woven fabrics, but has little impact on apparel and knitted fabrics. Replacement of textiles and other supplies: This includes non-woven fabrics, knitting textiles, plastic films, polyurea foam, wood pulp, leather, etc. This is determined by the cost and performance requirements of the product. The introduction of new, more economical and effective production processes: namely, the application of new competitive non-woven fabrics made of polymers, and the introduction of special fibers and non-woven textile additives.
The three major fibers used in non-woven fabric production are polypropylene fiber (62% of the total), polyester fiber (24% of the total) and viscose fiber (8% of the total). From 1970 to 1985, viscose fiber was most widely used in nonwoven production. However, in the recent 5 years, the application of polypropylene fiber and polyester fiber has begun to dominate in the field of sanitary absorption materials and medical textiles. In the early non-woven fabric production market, the consumption of nylon is very large. Since 1998, the consumption of acrylic fiber has increased, especially in the field of artificial leather manufacturing.
