A cotton spinning process for producing worsted pure wool yarn as claimed in claim 7 wherein: The antistatic agent reduces the electrostatic effect between the wool fibers, so that the fibers are more easily separated and carded during the spinning process, the addition of wool oil improves the lubricity and cohesion of the fibers, reduces the fiber breakage and scattering, the wool fiber is pre-humidified before entering the cotton spinning equipment, so that the moisture regain reaches 15%-22%, improves the softness and processability of the fiber, reduces the static electricity generation in the spinning process, improves the production efficiency and yarn quality.
