Abstract
The invention discloses a short fiber rotor composite yarn spinning method. According to a traditional composite yarn manufacturing method, filaments and short fibers are combined and twisted into composite yarns, the short fibers are not completely used in the traditional composite yarn manufacturing method, and twined fibers are inevitably produced. The short fiber rotor composite yarn spinning method comprises the following specific methods that doffing yarns on a winding drum are thrown into a rotor; two kinds of fibers are fed into a combing roller through a feeding roller via two feeding openings, the combing roller decomposes the fed fibers into filaments which enter the rotor through a fiber conveying tube, and under the centrifugal effect of the rotor, the filaments slide into a collecting groove along the side wall of the rotor to be collected as collected strips; an air extractor enables the inside of the rotor to generate negative pressure, the doffing yarns which are thrown through a doffing tube are in lap joint with the collected strips in the collecting groove, and the composite yarns are formed. The composite yarns are output through the doffing tube and a doffing roller and wind the winding drum through a winding roller. The short fiber rotor composite yarn spinning method can increase the kinds of the composite yarns which can be spun by a rotor spinning machine, the twined fibers can be prevented, and the strength of the yarns can be enhanced.
