The development of acupuncture machine textile industry is not only the traditional pillar industry of China's national economy, but also an important civil production industry. It is also an industry with obvious international competitive advantages. The non-woven equipment industry provides technical equipment for the textile industry. It is an important part of national equipment manufacturing industry. It is of great significance to improve the international competitiveness, technical level and industrial structure of textile industry. At present, China's non-woven equipment products are complete, including: chemical fiber machinery, spinning machinery, weaving machinery, knitting machinery, dyeing and finishing machinery and non-woven machinery. From 2006 to 2007, China's non-woven equipment industry as a whole showed a steady growth trend, with the total import and export volume maintained at more than 20%. In 2008, it was greatly affected by the financial crisis. Major economic indicators fell sharply year on year. From January to December 2008, the total industrial output value was 52.727 billion yuan, a year-on-year decrease of 6.12%; the total import and export volume in 2008 was 5.397 billion US dollars, a year-on-year decrease. 15.78%. From 2006 to 2008, with the strong support of the state, the active promotion of the industry and the unremitting efforts of the company, through the independent R & D and industrialization of non-woven equipment products represented by the following ten new equipment. With the continuous emergence of new products of China's non-woven equipment, the manufacturing level, product quality and production efficiency are further improved, and the market share of domestic non-woven equipment is continuously increased.
It can be seen from the exhibits exhibited in China that the technical level of China's non-woven machinery manufacturing enterprises has been greatly improved, and the gap between China and foreign advanced level has been narrowed. At present, China has been able to produce most of the single machines and production lines used in the production of non-woven fabrics, such as acupuncture, spunbond, spunlace, melt jet, pulp air flow network, thermal bonding, chemical bonding, etc. The company has a complete set of polypropylene hot rolling production line, polyester needle production line, polyester hot rolling and needle production line, and has developed SMS short melt composite production line and two-component spunbond composite production line. The draft forms include the negative pressure draft of the whole spinneret, the positive draft of the small spinneret, and the positive draft of the small spinneret. The maximum width of the domestic production line is 3.5m; it has roller type, double roller type, three roller type and flat platform type; among them, the suction roller and hot air dryer with advanced hydraulic seal water head and 90% honeycomb type through-hole rotary network structure are close to the international advanced level. China's acupuncture machine has basically formed a series, but it is a traditional vertical acupuncture method. It is a universal acupuncture machine with a maximum width of 10.5m and a maximum acupuncture frequency of 1800 times / second.
