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 โtorque lossโ in disc friction-spindles and also an essential feature in the operation of pin-spindles. An explanation is given for the dramatic ...
