Title
(EN) METHOD FOR DYEING SYNTHETIC MATERIALS WITH VAT DYESTUFFS
(FR) PROCEDE DE TEINTURE DE MATERIAUX SYNTHETIQUES A L'AIDE DE COLORANTS DE CUVE
Abstract
(EN)
A method is provided for dyeing a non-cellulosic organic material with a dye, preferably a vat dye, comprising (a) treating the material with a dye in the presence of a reducing agent and an alkali and (b) oxidising the treated material produced in step (a) characterised in that the concentration of reducing agent used in step (a) is increased above that used for conventional vat dyeing such that the resultant dyed material has a lightfastness of 5 or more by BS1006 B01 and B02 (1978) and/or has a washfastness or 5 or more by British Standard Test BS1006 C06.C2 (1981). Preferably the step (a) is carried out in the presence of an alkali in concentration of at least 0.5 molar, more preferably 1 molar or more and most preferably 1 to 4 molar. The method provides vat dyed non-cellulosic organic materials having a reflectance of infrared light of wavelength 400nm to 680nm of less than 15 %.
(FR)
On décrit un procédé de teinture d'un matériau organique non cellulosique à l'aide d'un colorant, de préférence un colorant de cuve, consistant (a) à traiter le matériau à l'aide d'un colorant en présence d'un agent réducteur et d'un alcali puis (b) à oxyder le matériau traité produit dans l'étape (a), ledit procédé étant caractérisé en ce que la concentration de l'agent de réducteur utilisé dans l'étape (a) est supérieure à celle utilisée dans une technique classique de colorant de cuve de telle manière que le matériau résultant teint possède une solidité à la lumière de 5 ou plus d'après le British Standard Test (norme d'essai britannique) BS1006 B01 et B02 (1978) et/ou une solidité au lavage de 5 ou plus d'après le British Standard Test BS1006 C06.C2 (1981). De préférence, on effectue l'étape (a) en présence d'un alcali dont la concentration molaire est d'au moins 0,5, préférablement 1 ou davantage, et idéalement entre 1 et 4. Ce procédé permet d'obtenir des matériaux organiques non cellulosiques teints dont la valeur de réflectance de la lumière infrarouge à une longueur d'onde comprise entre 400 nm et 680 nm est inférieure à 15 %.
