[Textile Knowledge] Development Of Ring Spinning Technology

After more than 100 years of development, the production technology of ring spinning has been greatly improved, and its adaptability to product varieties has been getting better and better. Its application scope has been greatly improved. The production of yarn from 5-300tex can be processed on ring spinning machine. Since twenty-first Century, with the continuous innovation of science and technology, the ring spinning technology has also developed very well. Through the combination with high technology, the ring spinning technology has made important breakthroughs in automation and intellectualization. The ring spinning technology has been presented to the public in a completely new way.

　　 (1) the introduction of composite spinning technology, combined with ring spinning frame, makes the product present a variety of raw materials and colors. Through the compound spinning technology, the variety and morphological structure of the products are varied, greatly increasing the application scope of the ring spinning technology, such as siro spinning, satin colored yarn, core spun yarn, etc.

(2) compact spinning, also known as compact spinning, has developed the ring spinning technology to a new stage. The compact spinning adds a fibrous condensation zone to the ring spinning machine before removing the spinning twisting trigonometry between the front roller and the twisting point. After the output of the front roller, the fiber whiskers are gathered and rotated by various fiber gathering devices, gradually changing from flat strip to cylinder, and the ends of the fibers are twisted into the yarn. Therefore, the yarn is very compact, and the yarn is smooth and hairless. The spinning line is much better than other spinning technologies in terms of the number of spinning parts or the quality of the products.

(3) in order to further improve the production efficiency of ring spinning technology and speed up spinning, the technology of low spinning tension is introduced into ring spinning, and the speed of ring spinning machine is improved by using new high-speed spindle and small diameter rigid collar. In foreign countries, spinning spindle speed has reached 25 thousand R / min. In domestic, through technical improvement measures, the speed of ring spinning machine can be increased by 15% to 20%.

(4) in order to effectively reduce spinning work, the automation and intelligent new technology factors are introduced into the ring spinning machine to solve the problem of employment, so as to improve labor productivity. At present, the long car with automatic falling sand has reached 18 million ingots, and the thickness has reached 900 thousand ingots, and the net has reached 600 thousand spindles. With the continuous development of process linking technology such as drawing, we believe that the whole process automation will soon appear.

(5) in order to further improve the product quality of ring spinning machine and reduce defective yarn, ring spinning technology can improve the stability of spinning and reduce the quality of yarn inconsistency by introducing efficient and high-quality spinning equipment, such as roller, cradle and traveller.

Through the development and innovation of these five symbolic aspects, the technical level of ring spinning has been greatly improved, making ring spinning technology an important position in the spinning field.
