摘　　要：借鉴混纺纱的混纺比例和其力学性能之间关系的研究方法对复合自捻纱线的复合比例和其力学性能之间的关系进行了研究和讨论。分别对腈/涤、毛/涤、麻/涤复合自捻纱线的断裂强力和断裂伸长率的测试数据进行曲线拟合,拟合相关系数最小值0.94,其余均在0.99～1.00,因此可以用拟合曲线预测复合自捻纱线的断裂强力和断裂伸长率。通过对腈/涤、毛/涤、麻/涤复合自捻纱线断裂强力和断裂伸长率的理论曲线进行分析,可以得到这3种复合自捻纱线满足后道工序加工要求的复合比例,腈/涤可以任何比例进行复合,而毛/涤复合时涤纶纤维含量要达到60%以上、麻/涤复合时涤纶纤维含量要达到70%以上才能满足后道工序加工要求。The relationship between composite proportion of composite self-twisted yarn and its mechanical properties is studied based on the research method on the relationship of the blending ratio of blended yarn and its mechanical properties. Respectively by curve fitting of testing data of breaking strength and elongation for acrylic /polyester,wool /polyester,ramie /polyester composite self-twisted yarns,fitting correlation coefficient minimum value is 0. 94,the rest value range is in 0. 99 ～ 1. 00,therefore the fitting curve can be used to predict the strength and elongation of composite self-twisted yarns. Through the analysis of the theoretical curve of the strength and elongation for acrylic /polyester,wool /polyester,ramie /polyester composite self-twisted yarns,it is obtained for the composite proportions of the three kinds of composite self-twisted yarns. For acrylic /polyester composite self-twisted yarn it can be in any composite proportion,for wool /polyester composite self-twisted yarn the polyester content should reach more than 60% and for ramie /polyester composite self-twisted yarn the polyester content is more than 70% so that the yarn properties can meet the processing requirements.
