摘　　要：采用氙灯光源照射模拟毛革制品的自然老化。测定毛革一些性质变化,以及用人工碱性汗液对老化后的样品做浸泡处理考察。实验发现,相同老化下醛鞣及铬鞣毛革的Ts均有类似下降,而透水汽值增加。汗浸处理后,铬鞣毛革的汗浸出物量随光照时间延长而增加,而醛鞣毛革却逐渐减低;其次,两种样品的相同性是汗浸面积收缩随光照时间延长而增加,而pH值均降低。By using Xe-lamp light as a natural ageing to fur leathers, some properties were tested and other properties were inspected after artificial sweat immersing. It was found that under the same ageing conditions the Ts of two tannage furs were all declined similarly and water vapor permeability values increased. With the extension of ageing time, the sweat extract quantity of chrome tanned fur leather increased and aldehyde tanned fur leather decreased. Area contraction increased and pH values decreased after artificial sweat immersing,which had the same behavior to two kinds of furs.
