Abstract

Method for dyeing and/or printing cellulose fibers and mixtures thereof with synthetic fibers, mercerized with an alkaline lye, wherein the mercerizing lye remaining on the mercerized or causticized cellulose fiber or mixtures thereof is totally or partially preserved, while waiting for the dyeing or printing of the yarns or fabrics.

Description

Il est connu que l'on peut merceriser des fibres cellulosiques avec des lessives de mercerisage et teindre par 1a suite. Le mercerisage, c'est-à-dire le traitement avec par example de l'Hydroxyde de soude, est un procédé d'ennoblissement connu pour le coton. Les procédés de mercerisage sont exécutés selon des manières très diverses. Mais le fil ou le tissu est toujours rincé ou neutralisé après le mercerisage et avant teinture pour le débarrasser de la lessive de mercerisage libre y adhérant.It is known that cellulosic fibers can be mercerized with mercerizing liquors and then dyed. Mercerization, that is to say treatment with, for example, sodium hydroxide, is a known finishing process for cotton. Mercerization processes are carried out in a variety of ways. But the thread or fabric is always rinsed or neutralized after mercerization and before dyeing to get rid of the free mercerizing lye adhering to it.

Il a été trouvé que l'on peut teindre le coton mercerisé à l'aide d'une lessive alcaline, avec un rendement coloristique accru, si l'on ne rince pas et ne neutralise pas la lessive de mercerisage se trouvant sur le fil ou le tissu après le procédé de mercerisage et si l'on exécute directement le processus de teinture de la matière mercerisée. De plus, il en résulte un raccourcissement du traitement et une économie notamment d'eau et d'énergie, ceci d'autant plus que les traitements habituels de neutralisation sont supprimés.It has been found that mercerized cotton can be dyed using an alkaline detergent, with an increased color yield, if the mercerizing lye present on the yarn is not rinsed and neutralized the fabric after the mercerizing process and if the dyeing process of the mercerized material is carried out directly. In addition, this results in a shortening of the treatment and a saving in particular of water and energy, this all the more that the usual neutralization treatments are eliminated.

La présente invention concerne un procédé pour la teinture de fibres cellulosiques naturelles ou régénérées et de leurs mélanges, mercerisés avec une lessive alcaline ou caustifiés, caractérisée par le fait que la lessive de mercerisage adhérant à la cellulose mercerisée est laissée totalement ou en partie, en attendant la teinture ou l'impression des fils ou tissus.The present invention relates to a process for dyeing natural or regenerated cellulosic fibers and their mixtures, mercerized with an alkaline or caustic solution, characterized in that the mercerization solution has inherent in mercerized cellulose is left completely or in part, pending dyeing or printing of threads or fabrics.

L'objet de l'invention porte également sur les fibres cellulosiques naturelles ou régénérées et leurs mélanges teints d'après cette méthode et de préférence sous la forme de textiles en maille.The subject of the invention also relates to natural or regenerated cellulosic fibers and their mixtures dyed according to this method and preferably in the form of knitted textiles.

Sous cellulose mercerisée, on entend le coton mercerisé et ses mélanges avec les fibres synthétiques, et avant tout le polyester ou de fibres cellulosiques régénérées, ces fibres ayant pû être traitées ou non avant mercerisage ou caustification, en vue de leur conférer des modifications transitoires ou définitives de leurs caractéristiques, leurs comportements concernant l'hydrophilité, l'affinité, la résistance ou autres.Under mercerized cellulose is meant the mercerized cotton and its blends with synthetic fibers, and primarily the polyester or regenerated cellulosic fibers, said fibers having p û be treated or not before mercerizing or causticizing, in order to impart their transient changes or definitive of their characteristics, their behaviors concerning hydrophility, affinity, resistance or others.

Il n'est pas important de savoir de quelle manière on mercerise avec de la soude caustique ou tout autre lessive alcaline. Conformément à l'invention, il est important que le fil ou le tissu ne soit pas spécialement préparé pour la teinture (rinçage neutralisation).It is not important to know how you mercerize with caustic soda or any other alkaline detergent. In accordance with the invention, it is important that the thread or fabric is not specially prepared for dyeing (neutralization rinsing).

Pour la teinture de telles fibres cellulosiques naturelles ou régénérées, les procédés habituels avec des colorants réactifs, de cuve ou directs entrent en ligne de compte. Il convient de teindre de préférence immédiatement après mercerisage proprement dit, soit sur l'installation mercerisage, soit sur une installation voisine ou suivante. Les colorants réactifs appropriés sont ceux utilisés habituellement pour la teinture de cellulose, sachant que l'on teint selon des conditions connues en soi, mais caractéri - sées par des rapports de bains courts notamment pour les fils.For the dyeing of such natural or regenerated cellulosic fibers, the usual processes with reactive, tank or direct dyes are taken into account. It should preferably be dyed immediately after mercerization itself, either on the mercerization installation, or on a neighboring or next installation. The suitable reactive dyes are those usually used for dyeing cellulose, knowing that the dyeing is carried out according to conditions known per se, but characterized by short bath ratios, in particular for the threads.

Les colorants réactifs appropriés de préférence sont les fluorochloropyr midine, monofluorotriazine, dichlorotryazine, trichloropyrimidine, dichlorochinoxaline, et méthyl-sulfoné -chloro-méthyl-pyrimidine, sachant que les colorants peuvent contenir plus d'un groupe réactif.The suitable reactive dyes are preferably fluorochloropyr midin, monofluorotriazine, dichlorotryazine, trichloropyrimidine, dichlorochinoxaline, and methyl-sulfonated -chloro-methyl-pyrimidine, knowing that the dyes may contain more than one reactive group.
