摘　　要：本文研究了铬鞣废液用于浸酸、铬鞣循环对产品质量的影响。结果表明,废液循环利用与传统工艺浸酸、铬鞣两种方法所制革的物理和化学指标十分相似。A Study was made on the influence of the recycling of the spent chrome tanning liquor in chrome tanning process upon the properties of the resultant leathers. A total of 25 cycles were carried out, using 100kg white weight per cycle. With the matching side being procesed by a conventional chrome tannage. The results showed that the physical and chemical test results for the leathers produced by the two tannage methods are very -similar,and that the influence that recycling of the spent chrome tanning liquor had on the finat leather colour was from no difference (83% of sides)to slightly lighter (17%).
