Abstract
Textile fabrics containing blends of synthetic fibers and cellulosic fibers are dyed in a continuous process such that the fibers of each class are substantially colored and a union dyeing is obtained. The method comprises continuously impregnating the fabric with a dyebath composition comprising a premetallized dyestuff and a reactive resin. After impregnation, the fabric is subjected to a temperature of from 280.degree. to 400.degree. F. to dry the fabric and to cure the dyebath composition on the fabric.
