Abstract

Various samples, including untanned, chrome tanned, glutaraldehyde tanned and formaldehyde tanned cattlehide collagen fibres, were prepared and treated in artificial perspiration. Preliminary studies on their dry heat shrinkage and thermal degradation behaviours were completed followed by study of changes in thermal behaviours due to the perspiration exposure. The mechanism of these changes is discussed. The influence of perspiration on the water vapour permeability and the hydrothermal stability of the crust leathers are also discussed.
