Abstract
The invention discloses a rotor composite yarn spinning method. According to a traditional composite yarn making method, short fiber using is not sufficient, winding fibers are generated inevitably, and yarn quality is affected. The method comprises the steps that long filaments of a long filament cylinder enter a spinning cup from a filament guiding tube and wind a winding cylinder; two kinds of fibers are fed into a carding roller through two feeding openings via a feeding roller respectively, the carding roller divides the fed fibers into single fibers which enter the spinning cup through the fiber conveying pipe, under the centrifugal effect of the spinning cup, the two different kinds of single fibers slide into condensation grooves along the side wall of the spinning cup to form condensation strips in a condensation mode; an air extractor enables negative pressure to be generated in the spinning cup, the condensation strips in the two condensation grooves wind the long filaments tightly, composite yarn is formed by further twisting of a twisting stopping disc; the composite yarn is output through a yarn guiding pipe and a yarn guiding roller and winds the winding cylinder. According to the method, the types of the composite yarn which can be spun by a rotor spinning machine can be increased, the winding fibers are prevented from being generated, and yarn strength is improved.
