Abstract

PURPOSE: To satisfactorily dye cellulose/polyester blended fibers by a one bath single step exhaustion dyeing method in a higher temperature and lower pH region by adopting a specific reactive dye when dyeing the blended fibers with a reactive dye and a disperse one. CONSTITUTION: The purpose is achieved by dyeing cellulose/polyester blended fibers by a one bath exhaustion dyeing method at 100-150 deg.C using a dye bath adjusted so as to have a pH value of 5-10 and including both (A) a known disperse dye and (B) a water-soluble tetrazo reactive dye of the formula [wherein, A is a (substituted) phenylene; R<1> is H or a lower alkyl; (n) is 0 or 1; X is a halogen; Y is SO2 CH=CH2 , SO2 C2 H4 W (wherein, W is a group eliminated by an alkali) or the like]. The adoption of the reactive dye enables us to attain a dyed product, where both kinds of fibers have been dyed so as to have the same color at high dye-affinity, having a deep color and excellent in color fastness to light and chlorine.
