dta, tg and tma were used to study wool samples of 64 quality, dyed and chromed in a dyeing bath at a low temperature (353 k), as well as by the conventional method involving boiling (369 k). the tma data allowed establishment of the basic temperatures connected with the $alpha$ $minus$ $beta$ transition of the wool keratin, the melting of the crystal regions and protein denaturation. it was shown that wool fibers chromed with 30 w. k//2cr//2o//7 at 353 k exhibit a decreased exothermic process in the range 700-750 k, which provides a possibility for evaluation of the effect of processing on the structural changes of the fiber keratin. 11 refs
