FT Raman Spectroscopic Studies of Wool

FT Raman spectroscopy has been used to investigate the structure of scoured wool cloth and fibres subjected to hydrogen peroxide bleaching. The advantages of FT Raman spectroscopy over conventional laser Raman and IR spectroscopic techniques are discussed. The spectra obtained are more highly resolved than have previously been presented; clear structural features are observed between 400-3400 cm-1 and assignments made of the vibrational modes. The results show that FT Raman spectroscopy can show structural changes in the fibre that are caused by treatments to which the fibre has been subjected, such as bleaching
