Abstract
Carbon-13 CPMAS NMR spectra of merino fine wool fibre (Quality 64S) were recorded as a function of heating from room temparature to 190°C. At about 170°C, the unsaturation of aromaticity increases. Analysis of the observed chemical shift value (at 170°C) of the main chain carbonyl carbons reveal that both the right-handed α-helix and β-sheet forms exist in the wool fibre.
