and relative humidity (RH) [ 9 ]. The moisture sorption isotherm of keratins has been the subject of several studies and models specially developed for describing the shape of the moisture sorption and desorption. The Vrentas and Vrentas model

prepared by mixing the dry mix with the required amount of water for about 3 min. After complete mixing, the resultant paste was molded into cubic specimens by using 1 inch cube moulds. The moulds, containing the pastes, were cured in 100% relative humidity
