中文摘要：为更好理解喷气涡流纺纱线结构对纱线强力的影响机制,实现纱线结构优化设计,首先在观察与分析喷气涡流纺纱线结构基础上,构建了喷气涡流纺纱线的几何结构模型;阐述了喷气涡流纺纱线内纤维的受力情况,以此得出喷气涡流纺纱线拉伸断裂强力的数学模型;通过对喷气涡流纺纱线拉伸断裂强力预测值与实测值的比较进行模型验证。研究结果表明:纱线强力预测模型对纱线拉伸断裂强力的预测结果与实测值较接近,同时,纱线中毛羽纤维造成的纱线半径计算的误差会影响到模型预测结果的精确性。

外文摘要：In order to well understand the influence of yarn structure of vortex spun yarn on its tensile properties and design the yarn structure,firstly,based on observation and analysis on structure of the vortex spun yarn,a geometric model of vortex spun yarn structure was proposed,then the stress of fiber in vortex spun yarn was analyzed,and the tensile strength model of vortex spun yarn was built.The predicted tensile strength of the vortex spun yarn obtained from the model was verified by that of tested data.It is found that the predicted strength data of the prediction model of yarn strength is very close to that of the measured data by comparison.Moreover,the error in the calculation of the yarn radius caused by the hairiness in the yarn can affect the accuracy of the model prediction results.
