摘要：
The tension of high performance yarn in the weaving region has influence on uniformity and pattern effect of fabric, which is difficult to be predicted in weaving process. In this paper, a modified Capstan equation including bending rigidity and power-law friction effects was developed, and solved numerically. The effects of the bending rigidity and power-law friction on tension ratio were analyzed. The experimental results were compared with the classical Capstan equation and modified one, showing that there was an approximate agreement between the modified tension ratio and experimental values. And therefore, the modified tension ratio could be used to characterize the tension variation and provide theoretical support for precisely controlling of yarn tension. (C) 2015 Elsevier Ltd.
