Continuous dyeing or printing process

Claim 1

A process for continuous dyeing or printing to obtain a two-color effect on mixed textile material, comprising a mixture of cellulose fibers and hydrophobic, synthetic polyester fibers, which comprises the steps of (a) applying a water and oil emulsion to the textile material, wherein the water contains, dissolved therein, a water-soluble dyestuff having affinity for the cellulosic fibers, wherein the oil is a halogenated aliphatic hydrocarbon containing at least partially dissolved therein, a disperse dyestuff having affinity for the polyester fibers, and wherein the emulsion contains a nonionic emulsifying agent and less than 0.6% of a water-soluble viscous solid having a high intrinsic viscosity selected from the group consisting of an alginate, methyl cellulose, hydroxyethylcellulose, carboxymethylcellulose, starch, hydroxyethylated starch, carboxymethylated starch, and (b) thereafter heating the dyed fibers to fix the dyestuffs thereto.
