The exact name of the nonwoven should be a nonwoven. Because it is a fabric that does not need to be spun woven fabric, only the woven short fibers or filaments are oriented or randomly stretched to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide application and many raw materials. The main uses of non-woven fabrics can be roughly divided into medical and sanitary fabrics, including surgical gowns, protective clothing, disinfecting wraps, masks, diapers, sanitary napkins, etc.; household decorative fabrics, including wall coverings, tablecloths, bed sheets, bedspreads Etc.; fabrics for follow-up, including lining, adhesive lining, flakes, styling cotton, various synthetic leather fabrics, etc.; industrial fabrics, including filter materials, insulating materials, cement bags, geotextiles, coated fabrics, etc.; Agricultural cloth, including crop protection cloth, nursery cloth, irrigation cloth, insulation curtain, etc.; other, such as space cotton, thermal insulation materials, oil absorbing felt, smoke filter, bag tea bags, etc. The three major fibers used in the production of nonwovens include polypropylene, polyester and viscose. Among them, polypropylene has the highest proportion, accounting for 62% of the total. In the early production market, nylon was used in large quantities.
Since 1998, the amount of acrylic fiber has started to rise, especially in the field of artificial leather manufacturing. In the past five years, the use of polypropylene fibers and polyester fibers has begun to dominate in the field of sanitary absorbent materials and medical textiles. At present, the domestic polypropylene fiber industry is characterized by a large number of manufacturers, small scale, strong geographical distribution, miscellaneous raw materials, and uneven product grades. In recent years, polypropylene fiber has developed rapidly. Enterprises have set up factories near the target market, and most of them are near consumption. Geographically, production enterprises were mainly distributed in coastal provinces and cities. With the development of the national economy, the inland provinces have also developed rapidly in recent years.
Among them, polypropylene filament manufacturers are mainly concentrated in Jiangsu, Zhejiang and Guangdong provinces; most of the staple fiber manufacturers are located in Shandong and Jiangsu provinces; Shandong has a batch of polypropylene staple fiber and tow equipment; Jiangsu is a traditional spinning township enterprise and tobacco wire The beam production enterprise is the main; the surrounding areas of Cixi, Zhejiang Province, a large number of small-scale polypropylene civilian silk manufacturers; Zhuji Datang socks industry developed, there are many family workshops like polypropylene elastic yarn manufacturers; Wenzhou area has a large number of spunbond nonwoven fabric manufacturers The Baigou area of Hebei is one of the largest distribution centers for luggage in China; the Guangdong ribbon industry is developed, mainly including non-woven fabric production enterprises and simple polypropylene filament factories for export packaging.
