    The DTG curves of highcrystalline cellulose were sharp and similar to those of lowcrystalline samples. The thermal degradation temperature of JC was decreased by ball milling, and its DTG peak shape became broad and low. These effects could be caused by the denaturing of noncellulosic substances such as hemicellulose and lignin.
