Spinning fibers into yarn generally go through the main processes of blowing, carding, drawing, roving, and spinning. Yarns and threads for high-end products also require additional combing operations.
Different processing procedures are required to produce cotton yarns with different requirements, such as spinning pure cotton yarns and polyester-cotton blended yarns. Due to different raw materials used, different physical properties of various raw materials, and different product quality requirements, when processing Different production processes are required. (With the update of modern equipment, the process has also been adjusted to varying degrees, and the equipment can merge some of these processes together, making the actual observation less work that was originally necessary)
