摘　　要：应用aQura仪分析了转杯纺精梳纱生产中从原料到末并条棉结数量、棉结直径的变化规律,得出开清棉工序的打手数量是影响成纱棉结的主要因素以及打手数量与开清棉棉卷的二次相关关系。探讨了依据精梳条棉结数量计算转杯纺精梳纱棉结数量的方法以及转杯纺对不同线密度纱线棉结的去除能力。利用MatLab数学软件中的函数polyfit求解最小二乘曲线拟合,得到精梳棉条棉结数与转杯纺成纱各分档棉结数的回归关系,对生产质量控制及工艺优化具有参考价值。Using aQura analysis instrument, the changing rule of the quantity and diameter ot neps Irom raw material up to the finishing drawing during processing combed yarns with rotor spinner was analyzed. It was found that the number of beaters in the process of opening and cleaning is the main factor that affects neps producing on finished yams, and the quadratic correlation between the number of beaters and opening and cleaning is also determined. This paper discusses the calculation of rotor combed cotton yam neps and the ability of rotor spinning to eliminate neps of yams with different linear density. The regression relation between the neps on combed sliver and the neps of different grades on rotor spun yarn was obtained by using the function polyfit in MatLab mathematical software to fit the least square curve. The research work is considered to be of reference value in quality control and process optimization.
