| 摘 要： | 通过实验对自捻纱线不同夹持长度下的断裂强度进行Weibull分布分析,纯腈纶自捻纱断裂强度的线性拟合相关系数的平方R2达到0.92 ～0.98,说明纯腈纶自捻纱的断裂强度符合Weibull分布,可以用Weibull分布来预测自捻纱线的断裂强度.同一种纯腈自捻纱线在不同夹持隔距下的Weibull模量是不同的,120 mm夹持隔距测试有捻区时Weibull模量β最大,表明腈纶自捻纱线的拉伸断裂强度值的离散性最小,其拉伸断裂强度的均匀性和可靠性最高.夹持隔距110 mm时,有捻区拉伸时η值最大,表明此时腈纶自捻纱的平均断裂强度最大.

| Abstract: | Through the experiment on the analysis of Weibull distribution of the breaking strength of self-twisted yarns in different clamping gauge, it is reached 0.92 - 0.98 for the square of correlation coefficient of linear fitting. It is proved that the breaking strength of the pure acrylic self-twisted yarns follows Weibull distribution, so Weibull distribution can be used to predict the breaking strength of pure acrylic self-twisted yarns. Weibull modules are different in different clamping gauges for the same acrylic self-twisted yams. Weibull modules have β maximum value in 120 mm clamping the twisted gauge and η maximum value in 110 mm clamping the twisted gauge. These two values correspond to the minimum discrete of the breaking strength and the maximum breaking strength average. |
