摘　　要：使用收缩温度,热重分析和差示扫描显微镜测量了鞣制度和热稳定性。还观察到了栗子和栎木鞣制的皮革在不同浓度下的形态。栗子鞣制的皮革的收缩温度低于quebracho鞣制的皮革的收缩温度。用20%和25%的栗子鞣制的皮革的鞣革程度高于用quebracho鞣制的皮革。shrinkage temperature,thermogravimetry and differential scanning microscope were used to measure tanning system and thermal stability.The tanned leather of chestnut and oak in different concentrations was also observed.The shrinkage temperature of chestnut tanned leather is lower than that of quebracho tanned leather.The tanning degree of leather tanned with 20%and 25%chestnuts is higher than that tanned with quebracho.
