Abstract

L'invention concerne un procédé de teinture rapide à un seul bain par matières textiles à base de fibres de cellulose avec des colorants azoiques insolubles dans l'eau. On effectue le piétage de la matière avec une circulation de bain d'au moins 5 fois par minute à des températures allant de 10 à 40 degrés c, on ajuste le pH à des valeurs acides tout en chauffant le bain à 30-50 degrés C, et en formant le colorant par diazotation et copulation de sorte que le temps de teinture ne dépasse pas 30 minutes. Application à la teinture de fibres cellulosiques.The invention relates to a rapid single bath dyeing process by textile materials based on cellulose fibers with water insoluble azo dyes. The material is stepped on with a bath circulation of at least 5 times per minute at temperatures ranging from 10 to 40 degrees C, the pH is adjusted to acidic values while heating the bath to 30-50 degrees C. , and forming the dye by diazotization and coupling so that the dyeing time does not exceed 30 minutes. Application to the dyeing of cellulosic fibers.
