The invention relates to a process for dyeing or printing textile material, wherein the textile material is first impregnated with a solution or dispersion containing a dyestuff and the impregnated textile material is then treated with the superheated vapor of organic solvents.

Dyeing and printing processes

A process for dyeing textile material of fully synthetic polymers ready for weaving by the exhaustion method, wherein dyeing is carried out at a temperature of at least 70.degree. C in a homogenous solution of one or several dyestuffs in a hydrophobic or hydrophilic solvent or solvent mixture, any sulphur atoms present in the solvent or solvent mixture being divalent or hexavalent.

Process for dyeing fully synthetic textile material

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.
