In 2020, The Capacity Of China'S Vortex Spinning Continued To Grow.

According to the technology, China's yarn can be divided into ring spinning, airstream spinning and vortex spinning. When the middle ring spinning is the most common and common spinning method, vortex spinning, air spinning, compact Siro spinning and siro spinning are also common processes. However, the competition between yarns of different processes and raw materials is also fierce. In terms of human cotton yarn, in recent years, due to the rapid development of vortex spinning, there has been some pressure on the sales of compact Siro spinning, air spinning and even ring spinning of human cotton yarn. The main reason is that the low price of vortex spinning makes up for some of its performance deficiencies such as strength and so on, so that its performance price ratio is better than others. Varieties.

Cost advantages of vortex spinning

The main reason for the cost advantage of vortex spinning is that the vortex spinning process is short, the ingots are less employed and the material consumption is low. with R30S For example, the cost of vortex spinning is lower than that of ring spinning. One thousand element / Tons less than compact Siro Spinning 2500/ Near the tonne, it is basically the same as air spinning. And data show that the application of vortex spinning on looms can improve loom production efficiency. 2% Above 。

There are still restrictions on the types and number of raw materials for vortex spinning.

Vortex spinning will not dominate all yarn markets because of its unique cost advantage. The above cost is reflected in the conventional model of cotton yarn. If it is replaced with other materials, such as cotton or polyester, or a fine variety, vortex spinning will reduce its price because of the decrease of spinning speed, the loss of raw materials or equipment, and the high demand for raw materials. Advantages.

It is not difficult to see from the following pictures that ring spinning (including Siro and compact Siro) has little change in spinning speed from coarse to fine yarn, while vortex spinning is in spinning. R30S-R50S Spinning speed began to decline rapidly in the process. R50S The speed of the above yarn slipped is more obvious, so the majority of the current spinning spun yarn is on the market. R10S-R40S But at the same time, in order to avoid this type of bidding situation, close siro spinning and siro spinning cotton yarn are currently focused on the number. R40S-R60S Mostly, even R60S Above.

2020 China's vortex spinning capacity continues to grow.

Two thousand and nineteen The year was a year of rapid growth of China's vortex spinning capacity, and the number of swirl spinning machines reached. Two thousand Near the stage, eddy spinning is mainly concentrated in Wujiang, Xinjiang, Korla, Zhejiang, Quzhou, Jiaxing, Jiangsu, Bazhou and other regions in Hangzhou, Jiaxing, Jiangsu. Two 。

However, with the growth of vortex spinning, the bidding price of the market is becoming more intense. Two thousand and twenty During the year, the cost of spinning cotton yarn was repeatedly low. During the period, though some of the rapier and air-jet looms were stimulated to use vortex spinning to produce grey cloth, but when it was still unable to stimulate the transfer of market demand, and even if the market price was low, the industry inventory began to grow again, and the industry was concerned. Six In the middle of the month, vortex spinning of cotton yarn is likely to fall again.

However, the profit of vortex spinning of cotton yarn has shrunk, but Two thousand and twenty There are still a lot of eddy current equipment coming to the factory in the year. Two thousand and twenty New equipment for vortex spinning in China Three hundred and eighty In the vicinity of Taiwan, In the emerging region, we should pay due attention to Peixian.

The internal and external environment and high equipment costs may limit the short term. The development speed of vortex spinning is worth mentioning. With the upgrading of the vortex spinning equipment, there is also a marked improvement in the types of raw materials and the number of branches. Secondly, the textile industry is increasingly aware of the vortex spinning industry. With the progress of these two points, vortex spinning will continue to develop in the following stages, but at the same time, it will also urge the development and follow-up of the domestic vortex spinning equipment.
