漫反射光谱评价不同环境因素对栀子染色真丝织物的老化影响

Evaluation of Aging Effect on Gardenia Dyeing Silk Fabric under Different Environmental Factors by Diffuse Reflectance Spectroscopy

采用漫反射光谱评价了不同环境因素对栀子染色真丝织物老化的变色规律和速度。结果表明:365nm光辐照和100℃条件对栀子染色织物的影响较大,并且光谱随老化时间增长呈渐变趋势;就室内常见污染气体乙酸、甲醛而言,乙酸气体对栀子染色真丝织物有较大损害,甲醛气体对栀子染色真丝织物影响较小。

Diffuse reflectance spectroscopy was applied to the evaluation of discoloration tendency and rate of aging of gardenia dyeing silk fabric under different environmental factors. It was shown that the dyeing silk fabric was predominantly affected when it was treated with a UV-radiation of 365 nm at 100 ℃, and that a trend of gradual change of spectra with the prolongation of aging time was observed. And when the dyeing silk fabric was placed in an atmosphere containing some common gaseous pollutants, such as vopours of acetic acid or formaldehyde, the gardenia dyeing silk fabric was found to be remarkably damaged by vapour of acetic acid, while the damage from the formaldehyde vapour was relatively insignificant.
