Spinning processing preparation technology of antibacterial composite knitting yarn

The invention discloses an antibacterial composite knitting yarn spinning processing preparation technology. The technology comprises the steps of raw material selection, core yarn preparation, wool mixing, wool combing, gilling, drawing, twistless roving preparation and core-spun composite yarn preparation. The wool fibers are used as coating fibers, and the antibacterial fibers are used as raw materials of the core yarns; carrying out two gilling processes and two drawing processes, and preparing untwisted roving by adopting untwisted roving equipment; covering yarn production equipment is adopted for preparing the antibacterial composite knitting yarn, and the twisting direction of core yarn is opposite to that of wrapping fiber. The core yarn adopts the antibacterial fibers, so that the composite knitting yarn has a good antibacterial effect. The core yarn has a certain twist degree and twist direction after being made. The core yarn is wrapped by other staple fibers through a core-spun process for produc
