Fatigue testing for twelve SG tubular fabrics with various textile parameters was performed under pulsatile pressure by an Accelerated fatigue tester. Two time points as of 0, and 1 x 10(8) cycles were selected. The percentage change of tubular diameter, fabric count, porosity, and water permeability before and after the fatigue testing were used to characterize the fatigue performance. Bursting work was used to indicate fatigue. The mathematical model of quantification theory I was used to analyze the influence of various textile parameters on the fatigue performance of SG tubular fabric. It was found that with the increase of fatigue time, bursting work decreased, and the predicting results by quantification theory I for the fatigue resistance were relatively accurate and the contribution ratio of each textile parameter to the fatigue performance was also obtained. Different textile parameter has different contribution ratio if different parameters were used to characterize the fatigue performance. Woven construction had more influence than yarn size on the fatigue performance, and yarn type had the least influence on it. Woven construction, yarn size, and yarn type had interactive influence on the fatigue performance. This can provide theoretical foundation for making better fatigue resistant SG tubular fabrics.
采用脉动压力疲劳试验机对具有不同纺织参数的 12 种 SG 管状织物进行了疲劳测试。选择了 0 和 1 x 10(8)个循环这两个时间点。使用管状直径、织物计数、孔隙率和水透过率在疲劳测试前后的百分比变化来表征疲劳性能。爆破功用于指示疲劳。使用定量理论 I 的数学模型分析了各种纺织参数对 SG 管状织物疲劳性能的影响。结果发现，随着疲劳时间的增加，爆破功降低，定量理论 I 对疲劳阻力的预测结果相对准确，还获得了每个纺织参数对疲劳性能的贡献比。如果使用不同的参数来表征疲劳性能，则不同的纺织参数具有不同的贡献比。机织结构对疲劳性能的影响大于纱线尺寸，纱线类型对其影响最小。机织结构、纱线尺寸和纱线类型对疲劳性能有交互影响。这可为制造更好的抗疲劳 SG 管状织物提供理论基础。
