The alkaline hydrolysis of wool keratin effected in ten hours at 25°, 40°, and 55°C. has been followed by determination of the weight, nitrogen, sulfur, and wet breaking strength of the residual wool fabric. The decrease in weight, nitrogen, sulfur, and wet breaking strength and the ratio of the sulfur of the hydrolysate to that of the residual wool have been shown to be greater, the greater the concentration of alkali or the greater the temperature. The weight of the residual wool has been shown to be a linear function of the alkali concentration, the nitrogen and sulfur to be functions of the form, y = axb. The ratio of sulfur to nitrogen decreased with increasing concentration of alkali or increasing temperature.
