The post-processing procedures of cotton spinning on twisting machine china include winding, doubling, twisting, singeing, spinning, baling, etc. The spun yarn spun through multiple processes using raw cotton and various chemical fibers as raw materials needs to be post-treated. To meet the different requirements of various yarn processes.

　　1. Improve the appearance quality of products

　　Different types of bobbins spun on twisting machine china still contain certain defects, impurities, rough details, etc., large defects, impurities, rough details, etc. can be removed in the post-processing process. In order to make the strands smooth and round, some twisting machines china are equipped with water tanks, which can be used for wet twisting. Some strands must be singed to remove surface hairiness and increase the sheen of the yarn. Products that require smooth yarn can be waxed.

　　2. Improve the intrinsic performance of the product

　　Ply processing can alter the yarn structure and thus its intrinsic properties. Different single yarns are twisted once or twice, and different production processes are used to achieve the purpose of improving the physical properties of the yarn such as strength, wear resistance, uniformity, gloss, and feel. Fancy twisting can also change the structure and form of the yarn, forming loops, loops, knots, points, knots, and special-shaped yarns with special effects such as different colors and different thicknesses.

　　3. Stable product structure state

　　Stable yarn twist and uniform single yarn tension in the strands are achieved through different post-processing procedures. If the twist of the yarn is unstable, it is easy to cause defects such as "kink", "braid" and "weft shrinkage". For yarns requiring high twist stability or high twist, wet heat setting is sometimes necessary. If the tension of each single yarn in the strand is not uniform, it will cause a "core-spun" structure of the strand, resulting in a decrease in the strength, elasticity and elongation of the strand.

　　4. Make the right roll form

　　In order to meet the needs of the subsequent process, the yarn should be made into different package forms. The packaging form must meet the requirements of large packaging capacity, easy to unwind at high speed, suitable for subsequent processing, and convenient storage and transportation.
