摘　　要：以制革常规染料作代表研究了ＣＯ２ 超临界流体介质代替水介质用于皮革染色的体系组成、工艺方法及最优化条件， 并与以水介质中的常规染色方法进行了比较。结果表明： ＣＯ２ 超临界流体介质代替水作介质可用于皮革染色， 并且具有节约染料、上染率高、染料分散均匀、结合牢固等优点， 是一种新的无污染的染色技术。Leather dyeing in CO 2 Supercritical Fluid (CO 2SCF) medium was investigated.The components of the dyeing system,the technology route and the optimum factors was determined.The results of dyeing in CO 2SCF and water mediums are also compared.It was showed that leather dyeing can be carried out in CO 2SCF medium,which has some advantages such as saving dye,high dye exhaustion,level color and high fastness.This is a new non-pollution leather dying technology.
