摘　　要：本文提出了一种纱条中纤维纵向排列的机制，建立了纱条截面纤维根数与纤维头端分布之间的关系，通过对纤维头端分布形式的不同假设下，运用蒙特卡罗方法对须条截面根数的不匀率模拟，表明须条不匀的最小极限排列是纤维头端呈均匀分布，而实际纱条的不匀则更接近PASCAL分布，并定义了一个表达须条中纤维排列状态的参数。In this paper , a fiber longitudinal arrangement mechanism in a yarn is proposed, and the relationship function between the fiber number in the yarn cross section and the distribution of fiber tips is established, under the different assumptions about the distribution of fiber tips, the unevenness of section fiber number is simulated by Monte Carlo method , the results indicated that the minimum limit of yarn unevenness is from the uniform distribution of the fiber tips, and the actual yarn is more close to PASCAL distribution, and a parameter is defined in the article to express the fiber tips arrangement
