Three Major Problems In The Development Of Jet Vortex Spinning Are Concerned By The Participants.

It caters to the needs of China's < a target= "_blank" href= "http://www.91se91.com/" > textile < /a > industry structure adjustment, technological progress and industrial upgrading, thus becoming a new hot spinning technology of the industry.

Recently, the China Cotton Textile Industry Association organized technical seminars from the upstream and downstream fields such as chemical fiber, spinning, weaving, spinning machines and equipment in Suzhou to hold a seminar on the development of jet vortex spinning industry. It carried out in-depth exchanges and discussions on the practical problems in the production practice of jet vortex spinning and the future development direction of the industry. Among them, the three major problems in the development of jet vortex spinning were concerned by the participants.

< /p >

< p > the process of jet vortex spinning usually requires direct application of bar spinning through the blowing carding machine and drawing frame. It reduces the spinning process and saves the floor area, and the equipment is highly automated. It can greatly reduce the labor intensity of workers and improve the quality of products.

It is estimated that the number of air-jet spinning is equivalent to 10 thousand spindles and 20 workers. The spinning speed reaches 450 meters / minute, which is more than 20 times of the ring spinning. The average 8 jet swirling spinning is equivalent to the output of 10 thousand ring spinning.

Ye Jianchun, vice president of China Cotton Textile Industry Association stressed at the seminar that it is these advantages that determine the development potential of air jet spinning in China.

< /p >

Less than 10 years ago, the development of air vortex spinning technology in China has been less than 10 years ago. Nowadays, only Japan Murata and Li Da, Switzerland, can produce jet spinning machines in large quantities.

At present, China's enterprises have introduced about 110 thousand different periods of air-jet vortex spinning equipment, accounting for 50% of the world's total, focusing on Zhejiang and Jiangsu.

The raw materials used by these enterprises are viscose, polyester and a small amount of cotton and other fibers.

Most of the products are pure viscose yarn and polyester viscose blended yarn, but the proportion of pure polyester, pure cotton, polyester cotton and other fiber blended yarn is smaller.

At P meeting, several air jet spinning enterprises mentioned the limitations of developing product varieties at present, hoping to cooperate with upstream chemical fiber enterprises to explore new fibers suitable for jet vortex spinning, and further enrich and expand the types of vortex spinning products.

< /p >

There are nearly 180 representatives attending this seminar, a large part of which come from the enterprises that are investigating eddy spinning technology. P

Therefore, for them, they are more concerned about the problems of eddy current spinning.

Representatives from the three aspects of investment and return, product development and promotion, and equipment maintenance input summed up the main problems that currently plagued the development of the vortex spinning industry.

< /p >

P > one is the large scale of investment.

Under the same scale, the jet vortex spinning machine has higher investment than ordinary ring spinning. Moreover, due to the characteristics of the high-tech electronic integrated equipment, its service life is much lower than that of the general ring spinning.

< /p >

< p > two is slow product promotion.

Because vortex spinning is similar to ring spinning, the vortex spinning is a substitute for ring spinning. The general user also uses the standard of ring spinning to measure the vortex spinning yarn.

The industry generally lacks knowledge of air-jet vortex spinning line. It has always been considered that its yarn feel is a shortcoming. It does not make good use of its good yarn and hairiness, and it has fewer advantages such as sizing, energy saving and emission reduction during weaving.

Therefore, the downstream fabric market for vortex spinning needs to be further developed and cultivated.

< /p >

< p > three is high maintenance cost.

At present, the jet vortex spinning equipment has not yet been domestically produced, and all rely on imports.

At the same time, because the scale of industry has not reached a certain level, it has not received enough attention from domestic equipment enterprises.

Therefore, after the introduction of vortex spinning, the related equipment has to be imported, which not only improves the cost, but also extends the maintenance cycle.

Therefore, the user enterprise appealed to domestic equipment enterprises to develop related equipment matching swirl spinning as soon as possible.

< /p >

< p > when it comes to the future development of vortex spinning enterprises, Zhu Beina, President of the China Cotton Textile Industry Association, said that the popularization and application of a new spinning technology require close cooperation between upstream and downstream enterprises. In the past few years, the development of eddy spinning products is mainly based on Murata company. In recent years, with the development of vortex spinning industry in China, some vortex spinning enterprises have actively developed new products, thus promoting the development of vortex spinning industry rapidly.

Therefore, she believes that the upstream and downstream enterprises should play a common role in the future to create favorable conditions for the healthy development of the vortex spinning industry in China.
