Fig. 9

Example of FTIR spectrum of oxohydroxide treated flax acquired in reflectance mode, showing certain bands assigned to components characteristic of cellulose (2900 cm−1 ν(C–H) stretching vibration, indicative of polysaccharides, the 1635 cm−1 corresponding to vibration of water molecules absorbed in cellulose, 1124 cm−1 ν(C–O–C) glycosidic ether band, 1041 cm−1 ν(C–OH) alcohol, and 889 cm−1 ν(C–O–C) arising from the polysaccharide components), and others indicating the effects of the treatment to the fibres (in the region of the spectrum from ~ 1350 to 1500 cm−1)
