Abstract

The invention discloses a control method for reducing spinning yarn breaks of a spinning frame. The method includes the start step, the small yarn spinning step, the medium yarn spinning step, the large yarn spinning step, the doffing step and the high-speed midway stop step. The medium yarn spinning step starts from the step S108, spinning is carried out at high speed, and when yarn on a bobbin accounts for 90-95% of spinning total amount, a full bobbin sensor outputs a full bobbin signal and spinning is carried out at low speed; when operation time is equal to Pg, the doffing step starts, the original full bobbin sensor is properly moved downwards, and when the yarn accounts for 90-95% of the spinning total amount, the full bobbin sensor sends out a signal, and low-speed spinning is carried out; when the full yarn position is reached after the low-speed operation time Pg, doffing is carried out, and the breakage rate of the yarn is effectively reduced.
