Process for the preparation of stilbene-disulphonic acids containing bis-alkoxy-triazinyl-amino, or derivatives thereof, characterized in that stilbene-disulphonic acids containing bis-chlorotriazinyl-amino, or derivatives thereof, are reacted with at least 10 molar equivalents, based on the stilbene-disulphonic acid compound, of a C,-C,-monoalkanol.

Process for preparing bis-alkoxy-triazinyl-amino-containing stilbene disulphonic acids or their derivatives

The present invention provides a process for removal of excess dye from newly manufactured printed or dyed fabric or yarn, comprising treatment with a rinse liquor comprising at least one enzyme selected from the group consisting of enzymes exhibiting peroxidase activity or laccase activity, an oxidation agent, and at least one mediator selected from the group consisting of aliphatic, cyclo-aliphatic, heterocyclic or aromatic compounds containing the moiety >N&mdash;OH, in particular 1-hydroxybenzotriazole.

Process for preparing substituted 4,4'-diaminostilbene-2,2'-disulphonic

The present invention provides a process for removal of excess dye from newly manufactured printed or dyed fabric or yarn, comprising treatment with a rinse liquor comprising at least one enzyme selected from the group consisting of enzymes exhibiting peroxidase activity or laccase activity, an oxidation agent, and at least one mediator selected from the group consisting of aliphatic, cyclo-aliphatic, heterocyclic or aromatic compounds containing the moiety &gt;N--OH, in particular 1-hydroxybenzotriazole.

Improved compositions for dyeing or printing textile materials of natural or synthetic fibers or mixtures of the two comprise polyaspartic acid or a derivative thereof and, if appropriate, wetting agents, emulsifiers, leveling agents, dispersing agents, reducing agents, oxidizing agents, solubilizing agents, defoamers, reist agents, pH regulators, complexing agents or several of these as further components.
