摘要:

为研究不同仪器弯曲性能测试结果的稳定性差异及其相关性,选取FAST-2弯曲仪和YG(B)022D型全自动织物硬挺度仪作为对比仪器,测试了15种棉织物、毛织物、丝织物在0度、45度、90度以及135度方向上的弯曲性能,计算了弯曲刚度测试结果的变异系数,并用统计分析方法进行数据处理。研究得到:硬挺度仪对3类织物的测试结果稳定性明显优于FAST-2弯曲仪,差异程度从高到低排序依次是丝织物、毛织物和棉织物。2种仪器对毛织物的测试稳定性均优于其他2类织物,且2种仪器测试结果具有很强的相关性。分析了两种仪器测试时产生误差的原因,并提出了减小误差的建议。

Abstract:

In order to find out the difference of test stability and the relationship between the test results of bending behavior defined by different apparatus, FAST-2 bending instrument and the automatic fabric stiffness tester were chosen for comparison. Fifteen fabrics including cotton, silk and wool fabrics were selected and the bending properties in 0°, 45°, 90°and 135° were tested. The coefficient of variation of bending rigidity was calculated. Then the data were processed with statistical analysis. It was found that the test stability of stiffness tester was better than FAST-2 bending instrument for all three types of fabric, the degrees of difference from highest to lowest is silk, wool and cotton fabrics. The stabilities of wool fabric tested by two apparatus were both best among three types of fabric. The bending rigidity tested by two apparatus had a strong correlation. Finally, the causes of test error of two apparatus were analyzed and suggestions were put forward to reduce the error.
