| 摘要:为准确评价婴儿纸尿裤的柔软度，探索建立人工评价和仪器测试的主客观相关性，提出了一种基于环形法对婴儿纸尿裤柔软度的测试方法。对实现婴儿纸尿裤柔软度表征的测试原理、装置基本要求进行了分析，采用自行设计的婴儿纸尿裤柔软度测试装置获得典型力值载荷-位移曲线，通过从曲线中提取特征参数表征柔软度，探讨测试方法的可行性与可靠性，并进行婴儿纸尿裤柔软度主观评价实验。结果表明，采用环形法可以快速、定量表征婴儿纸尿裤的柔软度，结果变异系数均<5.0，稳定性较好，对不同柔软度的婴儿纸尿裤有一定的区分度；2种方法测出的柔软度Pearson相关系数R=0.88，相关性显著，且聚类分析结果具有良好的一致性，验证了本方法测试婴儿纸尿裤柔软度的有效性。 |
| Abstract:To accurately evaluate the softness of baby diapers and explore the subjective-objective correlation between manual assessment and instrumental testing， a softness testing method for baby diapers based on the ring method was proposed. The testing principle and basic requirements of the apparatus for characterizing the softness of baby diapers were analyzed. A self-designed testing device for baby diapers softness was used to obtain typical force value load-displacement curve. Characteristic parameters extracted from the curves were employed to characterize softness， and the feasibility and reliability of the testing method were discussed. Meanwhile， a subjective evaluation experiment on the softness of baby diapers was carried out. The results showed that the ring method could rapidly and quantitatively characterize the softness of baby diapers， with all coefficients of variation less than 5.0， indicating good stability， and it had a certain ability to distinguish baby diapers with different softness levels. The Pearson correlation coefficient R of sofntness measure by two methods was 0.88， with a significant correlation. The cluster analysis results of the two methods were in good agreement， which verified the effectiveness of this method for testing the softness of baby diapers. |
