Abstract
Abstract A process for continuous dyeing or printing, wherein a textile matrial is impregnated or printed with an emulsion of water and a halogenated aliphatic hydrocarbon containing at least one dyestuff, at least one of the phases of the emulsion containing a thickener of high molecular weight, and the dyestuff thus applied is fixed by steaming or heating.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
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.
Claim 2
Dependent Claim
133 words
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.
Claim 3
Dependent Claim
17 words
The process of claim 1, wherein the oil is more than 80% by volume of the emulsion.
Claim 4
Dependent Claim
10 words
The process of claim 2, wherein the oil is tetrachloroethylene.
Claim 5
Dependent Claim
13 words
The process of claim 1, wherein the water-soluble dyestuff is a fiber-reactive dyestuff.
Claim 6
Dependent Claim
16 words
The process of claim 1, wherein the water-soluble viscous solid is sodium alginate or carboxymethyl starch.
Claim 7
Dependent Claim
12 words
The process of claim 1, wherein the cellulosic fibers are cotton fibers.
