| Summary: | 碩士 === 雲林科技大學 === 文化資產維護系碩士班 === 98 === Textiles and metals have both been in general use for a long time. Textiles and metals are traditional and ancient materials, but are also used in our daily lives. Related to the issues of textile preservation in museums, we understand that for long term conservation, if textiles are combined with metal it will be more difficult to control the conservation environment, because the requirements of temperature and humidity are different. Textiles are easily affected by temperature and humidity and can also deteriorate with the passing of time, thus increasing the challenges of their conservation. The accepted range of humidity for textile is 55% ±5: that for metals is 40% or lower. Because the humidity is inhomogeneous the different materials can be unstable. This experiment will focus on the impact of different metal corrosion products on un-degraded natural fibre textiles and evaluate their chemical and structural changes. Observations include the change in colour condition through the use of optical microscopy to research the interaction of textiles and corrosion products; scanning electron microscopy (SEM) may provide details of single fibre structural changes. The preliminary observations are: in metal corrosion, different ion solutions will affect cellulose fibres and protein fibres and cause colour change. Tensile strength became weaker and shrinkage occurred. Further research is continuing to find the causes of chemical and structural changes.
