Abstract:

In order to develop methods on designing environmental protective textiles, theoretical support and research methods are reasonably established from the process of the traditional national textile-handicraft. By scanning electrom microscopy, Raman spectroscopy, UV - visible spectroscopy and the other detection methods, the micro-structure, optical and other spectra characteristics of Liang cloth were analyzed, scientifically studied and theoretically explained aiming at analyzing the color formation source of the Liang cloth. The results show that the surface of the Liang cloth suffused with metallic purple, which belongs to the indigo dye chemical color and bright color of fabric structure. This is resulted from the comprehensive effcet of the chemical color and structural color of the indigo. The metallic luster is resulted from the thin film reflection and interference, and the purple derives from the micro-structure forms in the making process.

Key words: Liang cloth, structural coloration, Raman spectrum, national textile
