Fabric shape retention is a crucial property that impacts the durability and usability of fabric and which needs a convenient and accurate evaluation method. In the previous research, the automated crease recovery testing method was used to obtain fabric crease recovery information and evaluate the property of shape retention. Based on the previous research, an orthogonal test method was adopted to investigate the effect of different test parameters on the stability of shape retention detection in this paper. First, three factors, that of sample size, pressure, and pressure time, and three different levels of each factor were determined by the L9(3⁴) orthogonal test table. Next, the fabric shape retention indexes were detected by nine different test schemes, and the comprehensive score of shape retention index standard deviation was obtained as the evaluation criterion of the orthogonal test results. Finally, the optimal test scheme was determined by visual analysis and variance analysis. The results show that the sample size has a certain effect on the stability of shape retention indexes, while the pressure time and the pressure have no significant influence. The optimal test scheme is that the sample size is 30 cm × 30 cm, the pressure time is 60 s, and the pressure is 40 N. The test result measured by the optimal test parameters reveals excellent stability when the vertex angle standard deviation is 2.0°, the height standard deviation is 0.06 cm, and the shape retention area standard deviation is 0.16 cm². This paper provides an experimental basis for improving the accuracy of fabric shape retention evaluation method.

织物保形性是影响织物耐用性和可用性的关键特性，需要一种方便且准确的评估方法。在以往的研究中，自动折痕恢复测试方法用于获取织物折痕恢复信息并评估保形性能。本文在前人研究的基础上，采用正交试验方法研究了不同试验参数对保形检测稳定性的影响。首先，由L9(3 ⁴) 正交试验表。接下来，通过9种不同的测试方案对织物保形指数进行检测，得出保形指数标准差的综合得分作为正交试验结果的评价标准。最后，通过可视化分析和方差分析确定最佳测试方案。结果表明，试样尺寸对保形指标的稳定性有一定影响，而加压时间和加压压力无显着影响。最优测试方案为样品尺寸为30 cm×30 cm，加压时间为60 s，压力为40 N。通过最优测试参数测得的测试结果在顶角标准偏差为2.0时表现出优异的稳定性°，高度标准偏差为0.06厘米，² . 本文为提高织物保形性评价方法的准确性提供了实验依据。
