| Résumé : |
Dissolved dyes were recommended for use in effect finishes for patent leather in Europe in the sixties. Solvent-soluble dyestuffs (vat dyes) were mainly used for this despite their very poor fastness to migration.
During the same period, dyestuffs dissolved in organic solvents (usually DMF) were used in aqueous finishes. This dyeing method came from USA. In the sixties, Dr. Luch and his colleagues developed a system of liquid dyestuffs wich were suitable for both aqueous and organic finishes. At the same time a dyeing technique was developed which was similar to the padding process commonly used to dyes textiles. The leather was dyed in a through-feed machine. Dissolved metal complex dyes with a low salt content, which produced lighfast dyed aniline leather, were used in this process. The problems of this type of dyeing were very obvious. It was virtually impossible to obtain fastness to migration and fastness to perspiration/water spotting at the same time. |
