基于马鞍法的机织物弯曲性能测试方法的有效性研究

Effectiveness of bending performance testing for woven fabrics under saddle method

马鞍法是国标中测试织物弯曲性能的一种方法,虽然被写进国标当中,但是具体测试方法过程至今没有发布。为了探讨基于马鞍法对织物弯曲性能进行测试的有效性,本文研究现有织物弯曲性能测试方法的基础上,自制一套马鞍状织物弯曲的装置,将最大抗弯曲力FM和弯曲迟滞A作为测试指标,分别与KES风格仪测试指标中的平均弯曲刚度B和平均弯曲滞后量2HB进行线性相关性分析,结果表明:FM与B的相关系数为0.982,A与2HB的相关系数为0.907,进而验证了基于马鞍法对织物弯曲性能进行测试的有效性。

Although the saddle method is one of the standards for fabric bending performance test ,but the process has not issued up to now. This paper made a saddle shaped fabric bending device by learning the existing test methods of fabric bending performance deeply. The maximum bending force FM and the bending hysteres A are two test index in this paper. Through the design of orthogonal test, this paper studied the changes of the maximum bending force FM and the bending hysteres A to obtain optimal experiment scheme under the different experimental parameters. This paper took the data of the maximum bending force FM and the bending hysteres A to make a linear correlation .with the data of the average bending stiffness B and the average bending hysteresis 2HB took from the KES style instrument. The results showed that:the correlation coefficient of FM and B is 0.982,the correlation coefficient of A and 2HB is 0.982, so This test method is effective.
