Abstract
Abstract The present invention relates to a process for dyeing cellulose fibers or its union fibers which is effected according to an exhaustion dyeing method using a reactive dye containing at least one s-triazinyl group having a group of the formula: ##STR1## wherein M represents a hydrogen or an alkali metal, in an aqueous dyeing bath having a pH in the range of 4 to 10 and a dyeing temperature in the range of 110° C. to below 140° C.
