Abstract
Abstract A process for dyeing and printing textile materials made of or containing fully synthetic hydrophobic linear polymers which are free from amino groups, wherein the material is padded with a dispersion dyestuff containing at least one carboxyl group, the padded textile material is dried and printed with an alkaline printing paste, the fabric is thermo-fixed and the salt of the dyestuff containing a carboxyl group is subsequently washed from the printed areas.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
47 words
A process for dyeing and printing textile material made of or containing fully synthetic hydrophobic linear polymers which are free from amino groups, comprising the steps of 1. padding the material with a dispersion dyestuff containing at least one carboxyl group and no sulfonic acid groups, 2.
Claim 2
Dependent Claim
47 words
A process for dyeing and printing textile material made of or containing fully synthetic hydrophobic linear polymers which are free from amino groups, comprising the steps of 1. padding the material with a dispersion dyestuff containing at least one carboxyl group and no sulfonic acid groups, 2.
Claim 3
Dependent Claim
61 words
drying the padded textile material, 3. printing the dried textile material with a printing paste which contains heat-resistant alkaline compound as the only chemically reactive component, whereby the carboxyl-group-containing dyestuff forms a salt with the alkaline compound, 4. heating the textile material to fix the unreacted dyestuff thereon, and 5. washing the textile material to remove the dyestuff salt from the
