| Abstract: | By means of a torque testing apparatus with heat case and steam, the torque-twist relationship and torque-relaxation of cashmere yarn are investigated in comparison with wool yarn under two conditions of standard state and heating and steaming state, and the effect of pre-tension on the torque-relaxation of cashmere yarn is also investigated.It shows that (1) the torque of cashmere yarn is lower than that of wool yarn under the same conditions, (2) the torques of wet cashmere and wool yarns are both lower than that of cashmere and wool yarns under standard conditions, (3) the torque hysteresis for cashmere yarn is smaller and its level and rate of torque relaxations are lower than that of wool yarn, and (4) the percentage of residual torque of cashmere yarn increases with increasing pre-tensions (630 cN). |
