摘要
A process for dyeing polyester-cellulose union materials in a single bath containing a mixture of disperse and specified cellulose-reactive dyes by heating to a temperature of 100 DEG -140 DEG C and pH 5.0 to 5.5 until the polyester component is dyed then cooling to 80 DEG C, adding alkali and a neutral salt if the latter is not already present, and dyeing at 80 DEG -90 DEG C to fix the reactive dye.
