Abstract

Process for dyeing aminated cellulose/polyester blend fabric with fiber-reactive disperse dyestuffs Fiber materials comprising cellulose fibers or a mixture of cellulose and polyester fibers are dyed by first modifying the fiber material with one or more compounds containing amino groups and then dyeing the modified fiber material with a fiber-reactive disperse dyestuff in supercritical CO.sub.2.
