Industrial Technology Roadmap

At present, the domestic cotton spinning sets of new equipment have basically reached the international advanced level at the end of the last century and the beginning of this century.

The equipment of cotton spinning enterprises is close to and reached the international level at the end of the last century in 90s. The domestic cotton spinning sets of new equipment have basically adapted to the requirements of the renewal and pformation of the current cotton textile enterprises. 60%

In recent years, thanks to the appreciation of RMB

The cotton textile industry is faced with great difficulties because of many unfavorable factors such as the rising cost of labor and raw materials, shortage of funds and so on.

Cotton textile enterprises and related equipment enterprises are facing severe challenges.

financial crisis

The competition in the cotton textile market has been more dramatic.

It is imperative to speed up the technological pformation of cotton textiles and maintain the healthy development of the industry.

On the basis of years of research and development, the blowing carding machine has entered the practical stage in the 90s of last century.

According to the 1999 survey results of the China Textile Engineering Society, the technical and economic effects of the domestic blowing carding unit are mainly compared with the traditional roll forming process: compared with the production, the amount of labor in the blowing carding process is reduced by 77%, electricity consumption is saved by 9%~14%, the average cotton grading can be reduced by 0.5, and the production rate can be increased by about 9%.

The blowing carding process can also improve the working conditions and reduce the dust content in the workshop.

Because of the reduction of the floor area, it is advantageous for enterprises to adjust the layout of workshop production.

According to statistics, by the end of 2004, there were 1400 sets of blowing carding units, of which 300 were imported equipment, covering about 37% of cotton spinning spindles.

In 2007, 272 sets of new blowing carding units, including 72 imported units, showed that the continuous improvement of the domestic blowing carding unit basically kept up with the development of the international blowing carding technology, and could meet the production requirements of the enterprises.

The performance of JWF1204 carding machine produced by Zhengzhou spinning machine and the JWF1205 series carding machine produced by Qingdao has reached the international advanced level. However, the wear resistance, service life and international advanced level of the matching metal clothing are still different.

According to the "11th Five-Year plan" of comber, the proportion of combed yarn in China will reach 28% in 2010, but there is still a gap between the combing requirements and the current structural adjustment requirements.

The domestic comber can basically meet the requirements of use, and there is still a certain gap between the key components such as Xilin and so on.

The overall level of the non iron gun multi motor roving machine produced by Tianjin Hongda, Wuxi Hongyuan, Hebei Taihang and Qingdao global has reached the advanced level of similar products in the world.

The difference between the spinning frame and the international advanced level is mainly in the technological performance and high speed adaptability of the special parts such as steel collar, wire coil and spindle.

The proportion of China's non knot yarn must be further improved.

In 2007, 3768 new automatic winding machines were added nationwide, indicating the urgent need for cotton textile enterprises to increase the proportion of no yarn.

Qingdao Hongda independently developed and developed the JWF1001 automatic winding machine on the basis of the introduction of technical cooperation production. It has reached the advanced level of similar international famous brands and began mass production.

But metal trough, air splicer and electronic yarn clearer also rely on imported matching.

The JWF1001 automatic winding machine and the domestic yarn winding automatic winding machine combined with the long downer of the collective doffing have entered the production test stage.

The technology of fine link technology has entered the practical stage in the middle of 1980s.

The direct connection between the two processes with the largest number of people and the greatest labor intensity in cotton spinning production not only guarantees and improves the quality of the products, but also greatly reduces the employment rate, greatly improves the labor productivity, and better solves the contradiction between spinning speed and spinning reel which is difficult to solve in the long term of spinning production, and greatly improves the production efficiency of the ring spinning frame.

The technology of fine coupling is a symbol of the development of cotton spinning from traditional technology to modern spinning technology.

Shuttleless looms have been basically eliminated internationally, and the shuttling rate of looms in China's cotton textile enterprises is only 40%.

During 2002~2005, China imported 65 thousand shuttleless looms, of which 50 thousand were air-jet looms.

In 2006, 20983 shuttleless looms were imported and 22689 imported in 2007, mainly air-jet looms.

Cotton textile enterprises adjust their product structure, and the high-performance shuttleless looms that are in urgent need at present are mainly imported.

The electronic jacquard equipment matched with shuttleless loom can not meet the requirement of high speed.

The quality and process performance of equipment and special parts such as metal clothing, rubber coils, rubber rings, steel cradles, spindle cradles, combed cylinder, rotor spinning special parts, automatic winding metal grooves, air splicer, shuttleless loom, and electronic jacquard device are still different from those of the famous brands in the world, which affects the overall level of domestic textile equipment.

The gap between China's new sets of cotton spinning equipment and international advanced level is mainly reflected in automation, production efficiency, stability and reliability of equipment operation.

According to "the national medium and long term science and technology development plan", "the State Council on accelerating the revitalization of the equipment manufacturing industry" and "textile industry technological progress and development of steel", the "new generation of textile equipment" put forward by the China Textile machinery and equipment industry association has been included in the national science and technology support plan.

New generation

Cotton spinning

The development and development of equipment has been gradually put into production, which will greatly improve the quality of cotton textiles in China, improve the productivity of textile production, reduce the cost of products, and enhance the competitiveness of textile products.
