Technology Empowerment Goes Through The Development Of Industrial Textiles.

　　 The industry textile industry is widely used in medical and health, environmental protection, geotechnical engineering, transportation, emergency safety, aerospace and other fields. , With high technology content, wide application scope and huge market potential, it is a part of strategic new materials, and is also the focus of global textile development. Reviewing the 40 years of reform and opening up, industrial textiles are fast developing textile sub fields. From high performance fiber raw materials, equipment manufacturing level, to technological innovation and application development, industrial textiles can be described as "upper tube, lower tube, middle pipe air". Li Lingshen, vice president of China Textile Industry Federation and President of China Industrial Textiles Association, said that industrial textiles are still active in innovation and need to vigorously develop and expand the textile sub fields of application.

　　 Spunbonded melt spraying technology achieves three leaps

Industrial textiles are an important part of China's textile industry. With the rapid development of the industry, the contribution to the development of the national economy and people's lives and health is becoming larger and larger. Textile industry I know both inside and outside. In January 18, 1987, the Guangzhou second synthetic fiber factory introduced the German Spencer production line, which ended the history of China's no spunbonded nonwovens equipment and products. The production line was 2.4 meters wide and the production capacity was 1000 tons / year. The whole board and negative pressure draft technology were adopted. In July 11, 1992, the first domestic spunbonded nonwovens production line was put into trial run in Jinzhou nonwovens factory. The line adopted multi plate and small slot drafting method, with a width of 2.5 meters and a capacity of 1000 tons / year. In July 1993, Jiangyin Jinfeng special textile Co., Ltd. introduced the production line of 2.4 m width melt blown method of German fir house company. The Tianjin TEDA clean materials Co., Ltd. and Anhui Ao Hong superfine filter Co., Ltd. introduced the Accurate (precision) company's 1.6 m melt blown equipment. These continuous coiled production lines changed the history of China's production of melt blown sheets only by batch process. In May 1996, Beijing Bao Shi successfully developed the domestic melted spray mold with a width of 1 meters. Melt blown nonwoven production line Wide continuous coil production.

Over the past 30 years, China's spunbonded melt blown industry has experienced three stages: initial construction, rapid growth and adjustment and upgrading through digestion and absorption, independent innovation, product development and market expansion. At present, China's spunbonded melt blown industry has a wide range of products and widely used, and equipment manufacturing has made considerable progress. Some of its technology and product performance are close to or even surpassing that of the world's advanced level, and the raw materials include polypropylene, polyethylene, polyester, polyamide, polylactic acid and so on. Polyphenylene sulfide The production process includes hot rolling, needling, spunlace, melted shotcreting, SMS, multi-mode head assembly, two-component composite and so on. It not only meets domestic demand basically, but also has successfully exported to many countries in the world.

　　 Spunlace technology develops rapidly

In 1995, Hainan Xinlong company introduced the Spunlace production line of Europe with a width of 2.5 meters. In 1996, Ningbo Yu Hao company successfully installed the spunlaced production line in Taiwan, China. In 1998, the first domestic homemade Spunlace production line was developed in Changshu Feilong company. In 2001, the Hebei Dong Lun Industrial Limited company built the first domestic rotary drum Spunlace production line, and the production line equipment was provided by Zheng textile machine, with a width of 2.5 meters. Over the past 20 years, China's spunlaced nonwoven industry has developed rapidly. It has become the base of spunlaced nonwovens production and supply, and is also the manufacturer of wet wipes and medical products OEM. In recent years, the spunlaced nonwoven industry has gradually changed to product structure adjustment according to the market demand rule, and the industrial technology line and product category show a differential trend. At present, spunlaced nonwoven products are distributed in three main categories. The first category is a wide range of medical materials, mainly dry / wet wipes, surgical gowns and drapery, medical excipients, mask substrates, etc. the second category is industrial materials, mainly ordinary. Synthetic leather substrate Third kinds of materials for building decoration, including decorative wall cloth, curtain cloth, garment lining cloth, etc.

　　 Acupuncture technology market matures

Needle punched nonwovens in China started relatively late. In 1980s, the Shanghai Textile Machinery Research Institute introduced the design of the 112 needle punching machine, with a width of 1120mm and a frequency of 120 times / min. The Shanghai Textile Machinery Research Institute commissioned the Jiangsu Changshu Ren Yang agricultural machinery factory to manufacture the prototype. The Ren Yang agricultural machinery factory owned the needle punching machine manufacturing technology, and gradually formed the earliest needle punching machine production base in Changshu. In the late twentieth Century, acupuncture in China Nonwovens Market Gradually mature, rapid technological progress, fierce competition, began to appear type 250, 360 and other wide needling machine, acupuncture frequency reached 600 times / minute, needle machine varieties increased to the needle punching machine, jacquard needling machine and so on. At present, China's needle punching machine Machinable product width 8500mm, acupuncture frequency 1800 times / minute, but there is still a gap between the overall level and the international leading technology.

Since the reform and opening up, the rapid development of the national economy has not only provided the material basis for the development of science and technology in the industry, but also put forward new needs and directions for the scientific and technological innovation in the industry. Textile industry Enterprises and research institutes continue to support the overall development of the industry through independent innovation, integrated innovation, introduction, absorption and re innovation.
