China Cotton Spinning Equipment To A New Level

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%

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

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.

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.

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.

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.

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.

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 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.

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.

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.

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.
