The Effects of Anoxic Treatments on Color and Mechanical Property in Fabrics, Natural Dyed Fabrics, Papers, Natural Dyed Papers and Paints

Abstract

Fabrics, natural dyed fabrics, papers, natural dyed papers and paints were examined effects of colors and mechanical properties for materials of museum collections under anoxic treatment. Anoxic conditions using nitrogen and argon were oxygen concentration 0.01%, temperature(20℃, 25℃, 30℃), 50% RH and exposure time 30 days. Examined fabrics were raw silk fabric, UV irradiated raw silk fabric, degummed silk fabric, UV irradiated degummed silk fabric, cotton fabric, and UV irradiated cotton fabric. Natural dyed silk and cotton fabrics were dyed with fresh indigo,

Insight Into the Crystallinity of Chinese Ancient Silk by Synchrotron Radiation-Based and Conventional X-ray Diffraction Methods

“…In order to better understand the degradation process, evaluate the ageing status, and provide suggestions for the effective preservation of historic or archaeological silk, artificial ageing was often employed to stimulate the ageing process. Artificial ageing was achieved in a controlled environment with ultra violet(UV) radiation, soil embedding, volatile organic compounds(VOC), inorganic gas, animal flesh, or elevated temperature and humidity (Kang, 2009;Baek et al, 2012;Kim et al, 2012;Kim et al, 2013;Kim et al, 2014;Oh et al, 2014;Kim et al, 2016;Park et al, 2018;Park et al, 2019). Among these factors, dry-heat accelerated ageing was adopted in this study, based on the mechanism of ageing starting from a single fiber and then spreading to the whole fabric.…”
