A dyeing process comprising a number of liquid treatment steps such as washing and rinsing, after the application of the dyeing liquor to the textile, the fabric being centrifuged after each treatment step; and a centrifuge adapted for carrying out the centrifugation.

Dyeing process

The invention relates to a process of preparing 'one off effect' dyeings on paper or textile material comprising:

Continuous dyeing process

A substrate to which a dyestuff or optical brightener has been applied is aftertreated with a cationic or protonatable polymeric Product P selected from:

Aftertreatment of dyed substrates

The invention refers to a mixture of anionic dyestuffs having a skitteriness value at pH5 of 3-4 and a combinability value at pH5 of 4-5 and to a process for dyeing a fibre material comprising wool with such a mixture of dyestuffs. These mixtures of anionic dyestuffs give surface and fibre level dyeings.

Method for producing wool dyeings of improved levelness and dye mixtures

A process for dyeing a mixed fibrous substrate comprising applying to the substrate at least one disperse dye and at least one metal containing direct and/or reactive dye in the presence of a complexing agent having a stability constant K value with the metal of the direct or reactive dye of from 6 to 17 inclusive.

Dyeing of mixed-fiber substrates with a disperse dye and a metal-complex

The invention relates to a process for the production of anti-shrink treated wool dyeings in which wool is dyed with acid milling or metal complex dyes either before, after or between the steps of an anti-shrink treatment and, after the dyeing or the anti-shrink treatment or one of the steps of the anti-shrink treatment subsequent to the dyeing, is after-treated with a liquor containing a cationic fixing agent and a levelling/retarding agent having affinity for wool dyestuffs, and to a composition usable for such a process.
