After more than 100 years of development, the production technology of ring spinning has been greatly improved, the adaptability to product varieties has become better and better, the scope of application has been greatly improved, and the yarn count has increased from 5-300tex can be processed on ring spinning machines. Since the 21st century, with the continuous innovation of science and technology, ring spinning technology has also been well developed. Through the combination with high technology, ring spinning technology has also made important progress in automation, intelligence and other aspects. Innovative breakthroughs, ring spinning technology is presented to the public with a new look, mainly in the following aspects:
(1) Introduce composite spinning technology and combine it with the ring spinning machine to make the products diversified in raw materials and colors. Through composite spinning technology , product varieties and shapes and structures vary, which greatly increases the application scope of ring spinning technology, such as siro spinning, satin yarn, core-spun yarn, etc.
(2) Compact spinning, also called compact spinning, the research and development and production of this spinning technology have pushed ring spinning technology to a new stage. Compact spinning adds a fiber cohesion area in front of the traction device of the ring spinning machine, which basically eliminates the spinning twisting triangle area between the front roller and the twisting point. After the fiber slivers are output from the front opening of the front roller, they are gathered and rotated through various fiber gathering devices, and gradually transform from a flat ribbon to a cylinder. The ends of the fibers are all twisted into the yarn, so the yarn is very tight. The yarn has a smooth appearance and less hairiness. The spun yarn is much better than other spinning technologies in terms of spinnable count and product quality.
(3) In order to further improve the production efficiency of ring spinning technology and increase the spinning speed, low spinning tension technology is introduced into ring spinning. By using new High-speed spindles and small-diameter rigid collars are used to increase the speed of ring spinning machines. Abroad, the spinning spindle speed can already reach 25,000 r/min. In China, through technical improvement measures, the speed of ring spinning machines can be increased by 15% to 20%.
(4) In order to effectively reduce spinning labor, new technological factors of automation and intelligence are introduced into the environment. Spindle spinning machines are used to solve labor problems and improve labor productivity. Our country currently has 18 million long automatic sand-falling trucks, 900,000 thick and thin connections, and 600,000 fine connections. With the continuous development of process linking technologies such as drawing frames, it is believed that full-process automation will soon appear.
(5) In order to further improve the product quality of ring spinning machines and reduce the production of defective yarns, ring spinning technology actively introduces efficient and high-quality spinning equipment , such as rollers, weighting arms, travelers, etc., to improve the stability of spinning and reduce quality problems caused by yarn inconsistency.
Through the development and innovation of these five iconic aspects, the technical level of ring spinning has been greatly improved, making ring spinning technology continue to maintain an indispensable role in the spinning field. important position of substitution.
