Abstract: The stress-strain characteristics of white and canary coloured Chokla wool fibres and their thioglycollate-reduced fibres were studied in air (65 ± 5%, RH and 27 ± 2oC) and in water (27 ± 2oC). The data were analyzed by taking the regression of the curve parameters on the tex value of the fibre and the interaction of colour and treatment. The effect of thioglycollate treatment differs in white and canary coloured wools. The regression is significant in air test for stresses at 2% extension and post-yield slope and in wet test for stresses at 30% extension, yield and post-yield slopes and breaking stress. The interaction is significant in air test for stresses at 15 and 30 % extensions, yield and post-yield slopes and breaking stress and in wet test for all the cases except post-yield slope. The canary colouration modifies both the matrix and the microfibril, the extent of modification depending on the intensity of yellowness.
