【摘要】：古代絲織品上的染料幾乎全部自于自然界,其中大部分染料屬于植物染料。通過應(yīng)用微型光纖光譜技術(shù)無損檢測植物染料的類別,成功地獲得了茜草、黃檗、槐米、蘇木等7種植物染料的紫外-可見吸收光譜。此外,該技術(shù)還被應(yīng)用于7種染料的光照色牢度評估。結(jié)果表明:在4.32×104W/m2輻照度下光老化,黃檗的光照色牢度最差,靛青的光照色牢度最佳;而且應(yīng)用微型光纖光譜技術(shù)不僅能夠鑒別植物染料,還能評估染料的光照色牢度。該技術(shù)將為絲織品文物上的染料研究提供一種快速無損的檢測手段,有助于文物保護人員建立合適的光環(huán)境來減弱古代絲織品在展覽和保存時的光損傷。
[Abstract]:Almost all of the dyes on ancient silk fabrics come from nature, and most of them belong to plant dyestuffs. The UV-Vis absorption spectra of seven kinds of plant dyes such as alizarin, berberis, Sophora japonica, Sappa, etc., were successfully obtained by using micro-optical fiber spectroscopy to detect the types of plant dyes. In addition, the technique has been used to evaluate the light fastness of 7 dyes. The results showed that under the irradiation of 4.32 脳 104W/m2, the light color fastness of berberine berberis was the worst, and that of indigo was the best, and the micro-optical fiber spectrum technology could not only identify the plant dyes, but also evaluate the light color fastness of the dyes. This technique will provide a fast and nondestructive testing method for the study of dyes on silk fabrics, and help the conservators to establish a suitable light environment to reduce the light damage of ancient silk fabrics during exhibition and preservation.
