Abstract
A cotton-spun yarn spinning technique with quantitative drawing overload belongs to the technical field of spinning technologies and includes blowing, carding, pre-doubling, coiling, combing, drawing, rough spinning, fine spinning and spooling procedures. Overload quantitation is adopted for blowing, carding, pre-doubling, coiling, combing, drawing and rough spinning. The blowing procedure includes plucking, mixing, breaking, foreign fiber removing, feeding and coiling. A beater is lifted under variable frequency control. The carding procedure includes a licker-in, cylinders and doffers. Two ways are provided for doubling in the drawing procedure, sliver discharge is quantitated into 4.7-4.8g/m. Silver discharge in the rough spinning procedure is quantitated into 0.7-1.0g/m. By means of the cotton-spun yarn spinning technique, quantitation in the procedures is increased to 45%, drawing capacity can be reduced by 45%, and energy consumption can be saved by about 555,000 Yuan per year. The quality of products obtained via the technique is stable, slivers are uniform and high in strength, harmful hair is few, and the cotton-spun yarn spinning technique is applicable to industrial application and can be developed stably.
