汗液变化对皮凉鞋摩擦色牢度测试结果的影响

Influence of Sweat Change on Test Results of Rubbing Color Fastness of Leather Sandals

将人工汗液密封存放和敞口放置进行对比来研究该过程中pH值的变化,并研究工作汗液在浸泡毛毡过程中pH值的变化,通过汗液摩擦色牢度测试来探讨其对试验结果的影响。结果表明,随着时间的延长,密封保存下的汗液pH值略微下降,摩擦色牢度的测试结果比较稳定。随着时间的延长,敞口放置下的汗液pH值会明显降低,对摩擦色牢度的测试结果影响较大。在重复浸泡毛毡的过程中,工作汗液pH值会逐渐降低,对摩擦色牢度的测试结果有一定影响,在试验过程中不可重复使用来浸泡毛毡。

The changes in pH value of artificial sweat during sealed storage and open placement were studied,as well as the pH value changes of working sweat during the soaking of felt.The influence of pH value change on the ex⁃perimental results was discussed by testing the color fastness to perspiration rubbing.The results show that the pH val⁃ue of sealed sweat decreases slightly with the extension of time,and the test results of rubbing color fastness are rela⁃tively stable.The pH value of the opened sweat will decrease significantly with the extension of time,which has a great impact on the test results of rubbing color fastness.The pH value of working sweat will gradually decrease in the process of repeatedly soaking the felt,which has a certain impact on the test results of rubbing color fastness,it cant be reused to soak the felt during the experiment.
