Title
(EN) DYEING OF TEXTILES
(FR) TEINTURE DE TEXTILES
Abstract
(EN)
Cellulosic fibres or fabrics are dyed using pre-metallized acid dye by pretreating the fabric with a cationic agent having a plurality of cationic centres and optionally aftertreating the dyed material with a cationic polymer. The cationic polymer is desirably a polyquaternary amine material especially a poly(DADMAC) or polyvinylpyridine. Material dyed by the method has a 'washed out' appearance similar to fabrics dyed using the 'Jarofast' process, but the availability of a wide range of pre-metallized dyes gives a wider colour range, and the method enables a wider range of substrates to be dyed successfully, including lyocell fibre materials e.g. those sold under Courtauld's trademark 'Tencel' and blend/union materials with polyamides, easier processing and superior wash and light fastness.
(FR)
On teint des fibres ou tissus cellulosiques avec un colorant acide prémétallisé, en effectuant un prétraitement du tissu à l'aide d'un agent cationique présentant plusieurs centres cationiques, puis éventuellement un post-traitement du tissu teint à l'aide d'un polymère cationique. Le polymère cationique est, de préférence, une substance amine polyquaternaire, en particulier un poly(DADMAC) ou polyvinylpyridine. Un tissu teint par ce procédé présente un aspect 'délavé' similaire à celui d'un tissu teint suivant le procédé 'Jarofast'. La disponibilité d'une large gamme de colorants prémétallisés offre toutefois un choix de couleurs plus vaste et le procédé permet de teindre efficacement une gamme de substrats plus étendue (y compris des tissus en fibres lyocellulaires tels que ceux vendus sous la marque 'Tercel' de Courtauld et des tissus mélanges ou assemblages contenant des polyamides), un traitement plus facile et une plus grande solidité au lavage et à la lumière.
