Studious. Drawing process is an indispensable process in spinning process, and its main tasks are drawing, drafting, mixing and sliver forming. This process can improve the evenness of the middle and long sections and reduce the unevenness of the evenness. Drawing in spinning mills is easy to learn, and can be used by both men and women. After the opening and carding of fiber raw materials in the previous process, continuous semi-finished products, namely sliver, also known as card sliver, are made, but they cannot be directly spun into spun yarn, because the quality and structure of card sliver are far from meeting the requirements of final yarn formation, and the fiber straightness and separation are poor. For example, most of the fibers in the card sliver are still buckling or hooking, and some small fiber bundles exist; Although the fiber evenness of combed sliver is good, the evenness is poor. If these slivers are spun directly after roving, it will inevitably affect the yarn quality, so the drawing process must be carried out first.
