Title (EN) ECOLOGICAL AND SUSTAINABLE INDIGO DYEING PROCESS WITH LESS WATER
(FR) PROCÉDÉ ÉCOLOGIQUE ET DURABLE DE TEINTURE À L'INDIGO UTILISANT MOINS D'EAU
Abstract:
(EN) The invention is an indigo dyeing process; of which harms to environment are reduced and rendered with lower costs in comparison to traditional applications; in order to reduce water consumption and prevent undesired salt formation when dyeing warps, used in denim production; and includes the steps of pre-wetting warp yarns in the form of a rope, prior to indigo dyeing; by making use of solution containing 1-5 cc/L sodium hydroxide (Caustic), 5-8 gr/L wetting agent and 1-5 gr/L ion immobilizer; washing at least 1 time with water at 20-70°C, with the purpose of removal of wetting agent used at pre-wetting step; reduction of indigo coloring agent, resorting to acetol (hydroxyacetone) at the temperature of 27 °C for a period of 10 to 15 minutes, for that water insoluble indigo is made soluble; checking solution's color to check whether the reduction of indigo coloring agent is completed; passing yarns in the form of a rope through vessels, containing dye solution at 27 °C with a pH value of 11 to 13 pH, in which the obtained indigo dye is discharged/put for successive 3 vessels at least, ensuring oxidation of reduced indigo coming out of dye vessel with oxygen in the air, in other words, making it contact with air, with the purpose of stabilizing dye on yarns by rendering it insoluble in water; dipping yarns in the form of a rope, on which oxidized indigo coloring agent there is into solution at 70-75°C with a pH value of 4 to 5, containing 10-20 gr/L polyamine polymer and 5-15 gr/L acetic acid.
(FR) L'invention concerne un procédé de teinture à l'indigo, moins néfaste pour l'environnement et moins coûteux que les procédés classiques, qui permet une réduction de la consommation d'eau et évite la formation de sels indésirables lors de la teinture des fils de chaîne et qui est utilisé dans la production du denim. Ledit procédé comprend les étapes consistant à : pré-humidifier les fils de chaîne se présentant sous la forme d'une corde, avant la teinture à l'indigo, en utilisant une solution contenant 1 à 5 cc/l d'hydroxyde de sodium (caustique), 5 à 8 g/l d'un agent mouillant et 1 à 5 g/l d'un immobilisateur d'ions; les laver au moins 1 fois avec de l'eau à 20 à 70 °C, dans le but d'éliminer l'agent mouillant utilisé lors de l'étape de pré-humidification; réduire l'agent colorant indigo à l'aide d'acétol(hydroxyacétone) à la température de 27 °C pendant une durée de 10 à 15 minutes pour que l'indigo insoluble dans l'eau soit rendu soluble; vérifier la couleur de la solution afin de s'assurer que la réduction de l'agent colorant indigo est bien parvenue à son terme; faire passer les fils se présentant sous la forme d'une corde à travers des récipients contenant une solution de teinture à 27 °C présentant une valeur de pH de 11 à 13, le colorant indigo obtenu étant évacué/introduit dans 3 récipients successifs au moins, ce qui assure l'oxydation de l'indigo réduit sortant du récipient de teinture avec l'oxygène de l'air, c'est-à-dire par mise en contact avec l'air, dans le but de stabiliser le colorant sur les fils en le rendant insoluble dans l'eau; tremper les fils se présentant sous la forme d'une corde, sur lesquels se trouve l'agent colorant indigo oxydé dans une solution à 70 à 75 °C présentant une valeur de pH de 4 à 5 et contenant 10 à 20 g/l de polymère de polyamine et 5 à 15 g/l d'acide acétique.
