False twist

WebFeb 22, 2024 ยท (1) General false twisted yarn: that is, the fiber is twisted to a certain shape and then untwisted. The yarn maintains the bulkiness of the twisted state, but has no twist. The traditional processing method adopts the above three-step method, and is currently completed in one step on a false twist stretch yarn machine. WebAbstract. The role of yarn-bending, in particular bending hysteresis, is examined in twisting spindles and in the passage of yarns over guides. Hysteresis is shown to be the likely cause for the โ€˜torque lossโ€™ in disc friction-spindles and also an essential feature in the operation of pin-spindles. An explanation is given for the dramatic ...
