Abstract

Procédé de réalisation de teintures par création, sur la fibre, de colorants azoïques non hydrosolubles, selon la technique des colorants à la glace. On imprègne d'abord la matière fibreuse avec un copulant en bain alcalin et la développe ensuite en la traitant avec un bain de développement contenant le composé de diazonium, ce procédé est caractérisé en ce que le bain de développement contient un tri ou tétrapolyphosphate de métal alcalin et le pH du bain de développement est supérieur à 4,5 avant la copulation et inférieur à 9 après la copulation. Les teintures ainsi obtenues sont bien unies et très solides.
