Definitions
- the amount of the melamine compound depends in particular on the amount of dye used and the desired reserve or colored print, an amount of 50 to 150 g per liter of reserve preparation having proven to be advantageous.
- the melamine compound advantageously contains 1 to 4, preferably 2 to 3 acidic water-solubilizing groups, which can in particular be carboxyl or sulfonic acid groups.
- a melamine compound can contain only carboxyl groups or only sulfonic acid groups as well as both carboxyl and sulfo groups.
- R1, R2 and R3 may be the same or different.
- R1, R2 and R3 each represent phenyl.

Man erhält nach der vorliegenden Erfindung auf diese Weise Färbungen mit gutem Farbaufbau und hohen Eigenschaften. Die Färbungen sind somit licht-, wasch- und reibecht. Die Schädigung der Wolle ist gering. Man erzielt gute Ergebnisse sowohl auf filzarm als auch auf filzfrei ausgerüsteten Wollen. Das erfindungsgemässe Verfahren ermöglicht es, Fasermaterial gleicher Qualität auf einfache Weise in unterschiedlichen Farbtönen zu färben, was besonders bei der Teppichherstellung von grosser Bedeutung ist, weil damit Teppiche erzeugt werden können, die hinsichtlich Standfestigkeit und Glanz des Flors ein ausgeglichenes Bild zeigen. Das Verfahren ist zudem ökonomisch, weil meistens eine Zwischenwäsche und/oder -trocknung und eine kostenspielige Lagerhaltung grosser Mengen vorgefärbten Materials entfallen.In this way, dyeings with a good color structure and high properties are obtained in accordance with the present invention. The dyeings are lightfast, washable and rub-fast. The damage to the wool is minimal. Good results are achieved both on low-felt and on wool-free wool. The process according to the invention enables fiber material of the same quality to be dyed in a simple manner in different shades of color, which is of great importance particularly in the production of carpets because carpets can be produced which show a balanced picture with regard to the stability and gloss of the pile. The process is also economical because there is usually no need for intermediate washing and / or drying and expensive storage of large quantities of pre-colored material.
