Embedded type system positioning spinning method

An embedded type system positioning spinning method, comprising the steps of:

• on each draft element of a ring spinning frame, drafting a first short-staple roving and a second short-staple roving from two roving bobbins by feeding the first short-staple roving and the second short-staple roving to a draft mechanism through two guide funnels in parallel, respectively, wherein the draft mechanism comprises a first back roller, a second back roller, a first middle roller, a second middle roller, an apron, a first front roller and a second front roller, wherein the first front roller and the second front roller forms a front jaw therebetween;
• feeding a first filament and a second filament in parallel with the first filament to the first short-staple roving and the second short-staple roving respectively from a back end of the first front roller via a guide wire or a guide wheel, wherein after the first short-staple roving, the second short-staple roving, the first filament and the second filament enter the first front roller, the first filament and the second filament are parallel with the first short-staple roving and the second short-staple roving, respectively;
• after outputting the drafted first and second roving and the first and second filament from the front jaw, assembling the first short-staple roving and the first filament and twisting the assembled first short-staple roving and first filament to be a first intermediate yarn in a twisting triangle area, simultaneously, assembling the second short-staple roving and the second filament and twisting the assembled second short-staple roving and second filament to be a second intermediate yarn in the twisting triangle area, assembling the first intermediate yarn and the second intermediate yarn, and twisting the assembled first intermediate yarn and second intermediate yarn in the twisting triangle area to be a twisted yarn;
• and
• winding the twisted yarn onto a yarn bobbin via a guide wire.
