Due to the high substantivity to fibers in the reduced form of vat dyes, especially ercerized material can hardly be colored in this way. On the other hand, due to their chemical nature, leuco vat ester dyes, which are inherently leveling and are particularly suitable for light shades, enable perfect results to be obtained in many cases with the same fastness standard on cellulose fiber material.

Abstract

Les difficultés pratiques d'assurer l'uniformité lorsque l'on teint des tissus tricotés et du fil constitués de matière fibreuse cellulosique, dans des tons clairs avec des leuco-colorants à cuve d'ester, apparaîssent lorsque l'on veut appliquer à l'échelle industrielle ce procédé de teinture utilisable en soi. Selon la présente invention, on a désormais découvert qu'il est possible d'obtenir des temps de traitement total plus courts et simultanément une uniformité du processus de teinture en réalisant l'adjonction de la solution de colorant, sur une période plus longue de la phase d'absorption, au bain de teinture qui est déja à la température de fixation et renferme la matière textile et éventuellement d'autres additifs en dehors du colorant (en rapport avec le développement ultérieur du colorant).
