Title (EN) MANUFACTURING PROCESS FOR A DYED TEXTILE SUBSTRATE WITH AN IMPROVED LEVEL OF COLOURFASTNESS IN WET CONDITIONS
(FR) PROCEDE DE FABRICATION D'UN SUBSTRAT TEXTILE TEINT A SOLIDITE AU MOUILLE DE LA TEINTURE AMELIOREE
Abstract: front page image
(EN)The invention relates to a manufacturing process for a dyed textile substrate having an improved level of colourfastness in wet conditions. It relates in particular to a method of fixing the dye of a textile substrate, the substrate being dyed with a colouring agent, and the dyed substrate being subsequently treated by applying a natural or synthetic tannin. Said process is characterised in that when the textile has been dyed and has undergone tannin treatment, it undergoes a treatment in which a fixing agent is applied in the form of a solution or dispersion of a N-methylole organic compound and/or a polybasic amine compound. The invention improves, in particular, the level of colourfastness in wet conditions in dyed textiles comprising polyamide threads and elastothane threads.
(FR)La présente invention concerne un procédé de fabrication d'un substrat textile teint et présentant une solidité au mouillé de la teinture améliorée. Elle concerne plus particulièrement un procédé de fixation de la teinture d'un substrat textile consistant à teindre le substrat avec un colorant, puis à traiter le substrat teint par application d'un tannin naturel ou synthétique caractérisé en ce que le substrat textile teint et ayant subi le traitement par un tannin est soumis à un traitement consistant en une application d'un agent de fixation sous forme d'une solution ou dispersion d'un composé organique N-méthylolé et/ou d'un composé aminé polybasique. L'invention permet notamment d'améliorer la solidité au mouillé des surfaces textiles teintes comprenant des fils polyamides et des fils élasthanes.
