摘　　要：为进一步探究纱条中纤维的分布规律,模拟纱条中纤维的排列情况,对纤维左头端沿纱条轴向服从均匀分布的假设进行实验验证。通过示踪纤维的方法测定若干给定长度的生条片段中染色纤维的左头端数,并利用χ^2拟合检验法对所测数据进行检验。结果表明：生条中纤维左头端沿生条轴向服从均匀分布的假设是合理的;通过改变染色纤维的几何特征、种类及所取生条的片段长度考察了对纤维左头端数的影响,证明了所取生条的片段长度对纤维左头端沿生条轴向服从均匀分布的结论没有显著影响,最终为预测纱条的性能提供了基础。In order to further explore the fiber distribution and simulate the fiber arrangement in the sliver,the assumption that fibers left ends were uniformly distributed along the sliver axis in previous researches is required to verify by any experiment method. By counting the number of dyed tracer fibers contained in cotton sliver segment of given length,the verification was conducted using χ~2 inspection method. It can be seen from the results that the hypothesis that fiber left ends arrangement in the sliver were uniformly distributed is reasonable. In addition,the varied geometrical natures,type of the dyed fiber and the different length of carded sliver segment are selected in the experiment. The results also indicate that the geometrical features have no significant effect on the distribution of fiber left heads in the sliver,as well as the fiber type and the length of carded sliver segment,which provides the basis for predicting sliver properties.
