Manufacturing method and apparatus for torque-free singles ring spun yarns
An internal torque balancing method of short fiber yarns related to the art of textile and the manufacturing apparatus thereof. The present invention proposes a completely new mechanical processing method of single torque-free yarns, and applies it into the process of ring spinning. Said method accomplishes a machine and a possibility of processing single torque-free yarns within one processing step by simple improvement on the existing ring spinning machine. Said technique is applicable to the production of all types of short fiber materials, and can overcome the maximum bundle yarn count of Ne limit of the torque-free yarns processed by the existing physical balancing technique. Meanwhile, said technique can process the yarns with low twist, which is unable to be processed normally by the conventional ring spinning machine. The torque-free singles ring spinning machine has good mechanical behavior, good handle, and evenness without residual torque.
