Industry related knowledge

In traditional ring spinning production, the roving is drafted to the required yarn number through the drafting system, and the width of the whisker in the main drafting zone is several times the diameter of the spun yarn. At this time, the fibers are in a free state when they reach the front nip line. When these fibers leave the front nip line, they are twisted together to form a yarn, thus forming a spinning triangle. In this triangle area, the fibers are almost completely out of control, and the edge fibers leave the main body before twisting to form flying flowers, or one section of the fiber is twisted into the yarn body, while the other end forms hairiness. Therefore, the twisting triangle has an important influence on the formation of hairiness on the surface of the yarn and the generation of fly. In addition, when the fibers are twisted, the fibers outside the triangle area receive the greatest tension, while the fibers in the center receive the least tension. Therefore, the initial tensions of these fibers are different during yarn formation, which causes the subsequent processes and the final product to be stretched. Fibers with high pretension will break first, which will affect the strength of the yarn and the finished product. In order to facilitate twisting, the fibers in the main drafting zone should be parallel, straight and arranged as closely as possible to each other. The spinning triangle is a major defect of traditional ring spinning.

On the compact spinning frame, after passing through the main drafting zone, the strand passes through a set of suction compacting device before twisting. Through negative air pressure, relatively loose fibers accumulate in a straight line to eliminate the problems of ordinary ring spinning. The twisting triangle area makes the fiber change from the free loose and flat state before twisting to a straight and tight state, so that almost all the fibers can be twisted into the yarn during the twisting process, which greatly reduces the yarn Hairiness and flying, while the fiber arrangement structure in the yarn is closer, the force is even, and the cohesion between the fibers is enhanced, thereby also improving the strength of the yarn.

Because compact spinning reduces the hairiness of the yarn and improves the yarn strength, it provides good conditions for the subsequent processing. The quality advantages of compact spinning are well known, but to give full play to its advantages, it is inseparable from production. Basic management. Without strict quality management, stable quality yarn cannot be produced. If there is no standardized operation management, there will be a lot of defects in the production process. If there is no rigorous equipment management, some defects in the machinery and equipment such as crooked spindles or bad travellers will cause hairy yarn. Therefore, to fully reflect the superiority of compact spinning, it is inseparable from the basic management of quality management, operation management, and equipment management. With the progress of textile technology, the technology of compact spinning also has new developments. The introduction of compact siro spinning, compact core spinning, and compact core siro spinning technologies further broadened the application fields of compact spinning products.
