N2 - Thermal shrinkage will take place when leathers are heated to a high temperature, usually resulting in a decrease in its value and utility. In this paper, changes in mechanical behaviors by thermal shrinkage of leathers are studied systematically for the first time, and the influencing mechanism of thermal shrinkage on the mechanical behaviors of leathers are investigated and analyzed. The results indicate that, by thermal shrinkage, the aperture ratios of leathers are decreased and such mechanical properties of leathers as elastic modulus, tensile strength, and elongation at break are increased. The improvement in mechanical behaviors by hydrothermal shrinkage is at the cost of loss of utility and economic value of leathers. The results indicate that shrunken leathers may have a host of new applications because of their excellent mechanical behavior.
