丝织品在老化过程中及老化后在水、乙醇、丙酮中的失重行为

The loss in weights of silk samples during aging and of aged silk samples immersed in water, alcohol and acetone

本工作对丝织品在老化过程中及老化后在水、乙醇、丙酮中的失重行为进行了研究,目的是了解丝织品的老化机理并为丝织品清洗溶剂的选择提供参考。研究结果表明丝在光、热老化过程中均有失重,热老化丝织品在水中的失重相对于光老化小得多。所有失重均随老化程度及在溶剂中浸泡时间的增加而增加。乙醇、丙酮对老化丝的影响比水小得多。因此有机溶剂相对于水来说更适合用于丝的清洗配方中。

The loss in weights of silk samples during aging and of aged silk samples immersed in water, alcohol and acetone were researched. The aim of the research was to understand the mechanism of silk aging, and provided evidence for the selection of silk cleaning agents. The results showed that during heat and light aging, the silk samples weights all reduced , and the heat aged samples lost more in water than light aged samples did. The longer the samples were aged and immersed in solvents, the more weights were lost. The alcohol and acetone had less effects on aged silk samples than water did. Therefore, the organic solvents were more suitable for use in washing silk.
