Identification and analysis of mulberry silk and its fabric based onmicro confocal Raman spectroscopy
The confocal Raman spectroscopy was used to identify the fiber and fabrics of mulberry and tussah silk,and the influence of the types and colors of mulberry silk fabrics on Raman spectroscopy detection were analyzed.The results shows that there is no significant difference in Raman spectra between silks from the same variety and different regions.The principal differentiating factor between mulberry and tussah silk is the location of their main peak positions of the amide Ⅲ band,which appear at 1 229 cm-1 and 1 240 cm-1,respectively.The sensitive peak of β-folding structure is observed at 1 084 cm-1 and 1 094 cm-1.Furthermore,the Raman spectrum of tussah silk exhibits a distinctive peak at 905 cm-1.Consequently,the differentiation between mulberry and tussah silk can be achieved effectively through the confocal Raman spectroscopy technology.The type of mulberry silk fabric does not influence the Raman testing results,whereas the colour of mulberry silk fabric is the primary factor affecting the Raman testing results.
