  • Patent number: 7591861
    Abstract: The present invention discloses methods and kit-of-parts for treating keratinous fibres prior to dyeing to control and modulate dye uptake into the fibre. Organic solvents having log P of from ?4.0 to ?0.5 or from 0.5 to 4.0 are used to manufacture pre-treatment composition to be applied to the hair. When the hair is pre-treated with at least one organic solvent having a log P of from 0.5 to 4.0 the dye penetration into the keratinous fibres is enhanced, while pre-treating the hair with at least one organic solvent having a log P of from ?4.0 to ?0.5 reduces the dye uptake. One or more compositions to pre-treat the keratinous fibres can be effortlessly applied on different zones of the hair and can be left in place or removed prior the application of the dyeing composition.

  • Patent number: 5944852
    Abstract: Improved dyeing processes for yarn and fabric materials are described. Dye pattern definition on a textile material is enhanced by treating the fabric or the fibers from which it is made with a quaternary ammonium compound and by including in the dye composition a gum which will react with the quaternary ammonium compound to form a viscous gel. The gel minimizes migration of the dye prior to fixation of the dye, and therefore pattern definition is improved. Similar improvements can be obtained when space dyeing yarn that comprises fibers that have been so treated.

  • Patent number: 4190417
    Abstract: The present invention is concerned with a process for dry printing or dyeing of sheets. A foam structure is printed or dyed and placed in contact with the sheet to be treated. The composite is subjected to sufficient heat and pressure to destroy the foam structure without significantly damaging the sheet. The result is the sheet surface now appears to carry the printing or dyeing. Among the suitable carrier foams are polyurethane foams. The process finds particular utility in coloring difficult to dye substrates such as cotton, fiber glass or asbestos fabrics with water insoluble dyes.

  • Patent number: 4183727
    Abstract: An improved process for the preparation of water-insoluble azo dyestuffs on vegetable fibers according to the method of the ice-color technique had been found, impregnating first the fibrous material with an azo component and then developing it with a diazo solution of an aromatic amino compound in the neutral or slightly alkaline range, wherein an alkali metal borate is used to neutralize the diazo solution.The dyeings prepared in this improved dyeing process for ice color dyeing have very good fastness properties and are obtained with high color yields. The improvement of the dyeing process is seen in the use of alkali metal borate as a neutralizing agent, which avoids the creation of foam in the surfactant-containing diazo solution.
