摘　　要：探讨了棉纱线的捻度、直径与纱线支数之间的关系。选择12种不同支数的棉纱线,借助捻度仪改变各纱线捻度,获得了60种不同捻度规格的纱线,利用尼康数码显微镜测试纱线直径,建立棉纱线的直径分布数据库。结果表明:同种支数的棉纱线随着捻度的增加,其直径呈抛物线变化曲线,先增大后减小,其中抛物线的顶点所对应的纱线捻度为纱线最大直径的临界捻度点,同时通过建立的纱线直径数据库可直观读出棉纱线的支数。The relationship between twist,diameter and yarn count of cotton yarn was discussed.12 kinds of cotton yarn with different count were selcted,the twist of each yarn was changed with the aid of twist tester,60 kinds of yarn with different twist specifications were obtained.The diameter distribution database of various specifications of cotton yarn was established by testing the diameter of yarn with Nikon digital microscope.The results indicated that with the increase of twist,the diameter of cotton yarn with the same count showed parabola curve,which increased first and then decreased.The twist corresponding to the vertex of parabola was the critical twist point of the maximum diameter of the yam.In addition,the cotton count could be read directly through the established yarn diameter database.
