Analysis Of Ancient Textile Fibers And Dyes

With the development of modern archaeology,textile archaeology has gradually formed into a new interdisciplinary subject covering history,culture and technology,becoming an important branch of science and technology archaeology.Textile corruption easily aging,compared with other relics unearthed,it is difficult to survive,so now can save to the ancient textile rare,those lead to in the scientific research of the past are not valued.It is of great significance to study the abundant valuable information of the carrier.This paper mainly studies from two aspects: firstly,the fiber composition and fabric structure of the excavated textile are determined.A scanning electron microscope and Fourier infrared spectrometer were used to test the unearthed textiles,analyze their fiber composition and determine the category of textile fibers.The structure and structure of the fabric were analyzed by optical microscope.Secondly determine the dye composition of the unearthed textiles and whether it contains mordant.Based on the color of textiles and historical data,the fabric dyes were analyzed by Raman spectroscopy.Using the relative element method,the energy spectrum test was carried out to analyze whether the dye contained dye or not.Based on the experimental research and historical data,the dyeing of madder and indigo was simulated,and the textile dyes were further verified.After analysis and testing,the raw material of the samples 1,2,3,4 and 5 fibers are made of silk.Sample 1 is plain weave structure,sample 2 is twill weave structure,and sample 3 is four warp structures.The dye in sample 4 May be madder,the dye contains mordant,the sample 5 dyes are indigo,and the dye is not added to the mordant.This topic is a preliminary exploration of the direction of the research of textile archaeology,and further research is needed to better serve the archaeological community.
