COMPOSITION DE TEINTURE SOUS FORME DE GEL, PROCEDE POUR SA PREPARATION ET RECIPIENT CONTENANT LAGEL DYE COMPOSITION, PROCESS FOR PREPARING THE SAME, AND CONTAINER CONTAINING THE SAME
COMPOSITIONCOMPOSITION
L'invention concerne le domaine des teintures textiles, en 5 particulier les teintures contenant des colorants réactifs, qui sont utilisées généralement pour teindre des fibres cellulosiques.The invention relates to the field of textile dyes, in particular dyes containing reactive dyes, which are generally used for dyeing cellulose fibers.
Depuis quelques années, à côté des teintures traditionnelles en poudre, sont apparues des teintures liquides.In recent years, alongside traditional powder dyes, liquid dyes have appeared.
Un certain nombre de problèmes liés aux teintures en poudre, enA number of issues related to powder dyes, especially
10 particulier la dispersion de celles-ci au moment de l'ouverture de leur contenant et les risques de tacher les objets environnants, sont réduits de manière considérée comme satisfaisante à ce jour par l'utilisation des teintures, sous forme liquide.10 in particular the dispersion of these when opening their container and the risk of staining surrounding objects, are reduced in a manner considered satisfactory to date by the use of dyes, in liquid form.
Les travaux des inventeurs ont maintenant permis de déterminer 15 qu'il subsistait des risques d'éclaboussures par la composition de teinture liquide plus ou moins importants selon le système de conditionnement et d'ouverture du conditionnement de celle-ci par l'utilisateur.The work of the inventors has now made it possible to determine that there were still risks of splashing by the liquid dye composition which are more or less significant depending on the packaging system and on the opening of the packaging thereof by the user.
De plus, la sophistication croissante des machines à laver le linge ne va pas dans le sens d'une mise en œuvre de plus en plus simple des 20 teintures. En effet, au début du cycle de lavage des machines à laver de fabrication relativement récente, il y a rotation du tambour et vidange de la cuve ; la teinture se trouvant dans l'eau du tambour est alors évacuée de la machine à laver.In addition, the increasing sophistication of washing machines does not go in the direction of an increasingly simple implementation of the 20 dyes. Indeed, at the start of the washing cycle of washing machines of relatively recent manufacture, there is rotation of the drum and emptying of the tank; the dye in the drum water is then removed from the washing machine.
Il est donc souhaitable de disposer de teintures qui, tout en 25 présentant les avantages des teintures liquides, sont dépourvues des inconvénients de celles-ci.It is therefore desirable to have dyes which, while having the advantages of liquid dyes, are free from the drawbacks thereof.
Il est par ailleurs connu de l'état de la technique de présenter des compositions de teinture à l'état gélifié.It is also known from the state of the art to present dye compositions in the gelled state.
Ainsi, US 5,356,439 décrit une composition de teinture sous 30 forme de gel pour teindre les fibres naturelles ou synthétiques, comprenant :Thus, US 5,356,439 describes a dyeing composition in the form of a gel for dyeing natural or synthetic fibers, comprising:
- 0,001 à 5% en poids de colorant ;- 0.001 to 5% by weight of dye;
- 0,01 à 8% en poids d'un agent gélifiant choisi parmi le guar, le xanthane ou une composition basée sur la cellulose ; - 0,01 à 4% en poids de modulateur de viscosité ;- 0.01 to 8% by weight of a gelling agent chosen from guar, xanthan or a composition based on cellulose; - 0.01 to 4% by weight of viscosity modulator;
- 0,01 à 2% en poids de conservateur ;- 0.01 to 2% by weight of preservative;
- 0,99 à 67% en poids d'eau déionisée ; et- 0.99 to 67% by weight of deionized water; and
- 0,01 à 25% en poids d'un agent réducteur mercaptan. US 5 153 317 décrit une composition pour contrôler la rhéologie d'une peinture aqueuse pour teindre les fibres naturelles ou synthétiques comprenant :- 0.01 to 25% by weight of a mercaptan reducing agent. US 5,153,317 describes a composition for controlling the rheology of an aqueous paint for dyeing natural or synthetic fibers comprising:
- 1 à 30% en poids de gomme xanthane, de gomme welam, de gomme rhamsan ou leur mélange (A) ; - 70 à 99% en poids de polysaccharide soluble dans l'eau sélectionné parmi les alginates, les polymères cellulosiques, les amidons, les gommes guar et leur mélange (B) sous réserve que si A est un xanthane et B est un guar, alors la composition comprend au moins 25% de A et au plus 75% de guar. Cependant, aucune des solutions préconisées dans ces documents ne permet l'obtention de teintures sous forme de gel présentant une gélification rapide lors du procédé de fabrication et une tenue suffisamment bonne du gel pour répondre aux exigences d'une teinture mise en œuvre dans une machine à laver le linge. Par ailleurs, les travaux des inventeurs ont permis de déterminer que l'on pouvait obtenir à la fois une bonne prise en gel de la teinture, sans recours à des systèmes d'agitation ou d'homogénéisation sophistiqués, ainsi qu'une bonne conservation de la teinture en gel, et des conditions optimales d'utilisation de la teinture en gel, lorsque celle-ci était conditionnée dans un récipient en forme de barquette fermée à l'aide d'un opercule, comprenant un moyen de fermeture amovible.- 1 to 30% by weight of xanthan gum, welam gum, rhamsan gum or their mixture (A); - 70 to 99% by weight of water-soluble polysaccharide selected from alginates, cellulosic polymers, starches, guar gums and their mixture (B) provided that if A is a xanthan and B is a guar, then the composition comprises at least 25% of A and at most 75% of guar. However, none of the solutions recommended in these documents makes it possible to obtain dyes in the form of gel having rapid gelling during the manufacturing process and sufficiently good resistance of the gel to meet the requirements of a dye used in a machine. washing clothes. Furthermore, the work of the inventors made it possible to determine that it was possible to obtain both a good gel setting of the dye, without recourse to sophisticated stirring or homogenization systems, as well as a good conservation of gel dye, and optimal conditions for using the gel dye, when it was packaged in a container in the form of a container closed with a lid, comprising a removable closure means.
L'invention a pour objet un ensemble comprenant un récipient et une composition de teinture sous forme de gel, le récipient comprenant une barquette, un opercule fermant ladite barquette, et un moyen de fermeture amovible d'une ouverture prévue dans l'opercule.The subject of the invention is an assembly comprising a container and a dye composition in the form of a gel, the container comprising a tray, a lid closing said tray, and means for removably closing an opening provided in the lid.
Le moyen de conditionnement sous forme de barquette permet ainsi d'obtenir une prise en gel de la teinture par simple addition de l'agent épaississant directement dans la solution de teinture, sans agitation mécanique du milieu. En outre, grâce au moyen de fermeture amovible de la barquette, la composition de teinture en gel peut diffuser dans l'eau de la cuve de la machine à laver de façon progressive, en évitant les pertes de teinture lors de l'étape de vidange de la cuve avant lavage. La composition de l'invention comprend un épaississant ou un agent de gélification. Parmi les agents gélifiants ou épaississants disponibles, les gommes végétales présentent les meilleurs résultats, tant en ce qui concerne la tenue du gel, la compatibilité avec les matières colorantes, que l'absence d'amas se déposant sur les textiles lors du procédé de teinture. Des résultats particulièrement bons ont été obtenus lorsque l'épaississant était une gomme xanthane.The packaging means in the form of a tray thus makes it possible to obtain a gel setting of the dye by simple addition of the thickening agent directly in the dye solution, without mechanical agitation. middle. In addition, thanks to the removable closure means of the tray, the gel dye composition can diffuse gradually into the water of the tank of the washing machine, avoiding loss of dye during the emptying step. of the tank before washing. The composition of the invention comprises a thickener or a gelling agent. Among the gelling agents or thickeners available, vegetable gums have the best results, both with regard to gel strength, compatibility with coloring matters, and the absence of lumps deposited on textiles during the dyeing process. . Particularly good results were obtained when the thickener was a xanthan gum.
Avantageusement, la composition de teinture selon l'invention contient : un colorant textile, notamment un colorant réactif pour fibres cellulosiques ;Advantageously, the dye composition according to the invention contains: a textile dye, in particular a reactive dye for cellulosic fibers;
- une gomme xanthane ; et- xanthan gum; and
- de l'eau.- some water.
La gomme xanthane apporte les avantages suivants :Xanthan gum provides the following benefits:
- celle-ci peut être ajoutée à la fin du procédé de production de la composition finale de teinture telle qu'elle est mise en œuvre par l'utilisateur ;- This can be added at the end of the process for producing the final dye composition as it is used by the user;
- l'addition de gomme xanthane à la dernière étape du procédé de fabrication, c'est-à-dire après mélange des différents constituants de la teinture à partir des colorants de base pour obtenir la teinte souhaitée, évite notamment le recours à une pompe pour l'injection de la composition de teinture et donc les problèmes liés au rinçage de la pompe ;- the addition of xanthan gum at the last stage of the manufacturing process, that is to say after mixing the different constituents of the dye from the base dyes to obtain the desired shade, in particular avoids the need for a pump for the injection of the dye composition and therefore the problems associated with rinsing the pump;
- l'utilisation de gomme xanthane permet une prise en gel de la composition de teinture sans avoir recours à une agitation vigoureuse, la simple manipulation du récipient de conditionnement en vue de la fermeture de celui-ci par le fabricant étant suffisante pour répartir la gomme xanthane au sein de la composition et assurer la prise en gel subséquente ;the use of xanthan gum allows gel setting of the dye composition without having to use vigorous stirring, the simple manipulation of the packaging container with a view to closing it by the manufacturer being sufficient to distribute the gum xanthan within the composition and ensuring the subsequent gel setting;
- l'utilisation de gomme xanthane est particulièrement compatible avec l'acidité des compositions de teintures réactives dont le pH se situe généralement entre 3 et 5, avantageusement aux environs de 4, en particulier, le gel formé reste stable dans le temps ;the use of xanthan gum is particularly compatible with the acidity of the reactive dye compositions whose pH is generally between 3 and 5, advantageously around 4, in particular, the gel formed remains stable over time;
- la présence de gomme xanthane dans le gel permet une bonne dissolution de la composition de teinture dans le bain de teinture, notamment dans le bac d'un lave-linge automatique sans dépôt d'amas ou grumeaux à la surface du linge ;- The presence of xanthan gum in the gel allows good dissolution of the dye composition in the dye bath, especially in the tank of an automatic washing machine without deposit of lumps or lumps on the surface of the laundry;
- la perte de matière due à la vidange préalable des machines à laver de fabrication récente est rendue pratiquement nulle par rapport à la teinture liquide.- the loss of material due to the prior emptying of washing machines of recent manufacture is made practically zero compared to the liquid dye.
La quantité de gomme végétale est avantageusement d'au moins 0,5 g/100 g, de préférence au moins 0,7 g/100 g de composition finale et avantageusement d'au plus 2,5, de préférence au plus 2 g/100 g de composition finale, une quantité particulièrement préférée étant d'environ 1 g/100 g.The amount of vegetable gum is advantageously at least 0.5 g / 100 g, preferably at least 0.7 g / 100 g of final composition and advantageously at most 2.5, preferably at most 2 g / 100 g of final composition, a particularly preferred amount being approximately 1 g / 100 g.
Pour une viscosité finale recherchée, la quantité de gomme varie en fonction de la nature du composé colorant.For a desired final viscosity, the amount of gum varies depending on the nature of the coloring compound.
Ainsi, pour les teintures contenant des concentrations élevées de composé(s) colorant(s), la quantité de gomme ajoutée sera située dans la limite supérieure de la fourchette indiquée, alors que pour les teintures contenant des concentrations plus faibles de composé(s) colorant(s), la quantité de gomme ajoutée sera située dans la limite inférieure de la fourchette indiquée. Cette quantité est aisément déterminée par l'homme du métier au moyen d'essais de routine.Thus, for dyes containing high concentrations of coloring compound (s), the amount of gum added will be within the upper limit of the range indicated, while for dyes containing lower concentrations of compound (s) dye (s), the amount of gum added will be within the lower limit of the range indicated. This quantity is easily determined by a person skilled in the art by means of routine tests.
Le pH de la formulation de teinture en gel de l'invention est généralement de 4 ± 1. Des résultats particulièrement intéressants, notamment une viscosité plus élevée sont obtenus lorsque la composition comprend une combinaison de gomme xanthane et de gomme guar.The pH of the gel dye formulation of the invention is generally 4 ± 1. Particularly interesting results, in particular a higher viscosity are obtained when the composition comprises a combination of xanthan gum and guar gum.
Avantageusement, le rapport pondéral de gomme xanthane à la gomme guar est supérieur à 1 , de préférence supérieur à 1 ,5. Un autre objet de l'invention est par conséquent une composition de teinture en gel comprenant :Advantageously, the weight ratio of xanthan gum to guar gum is greater than 1, preferably greater than 1.5. Another subject of the invention is therefore a gel dye composition comprising:
- un colorant textile, notamment un colorant réactif pour fibres cellulosiques ; - un agent gélifiant consistant en un mélange de gomme xanthane et de gomme guar, et- a textile dye, in particular a reactive dye for cellulosic fibers; a gelling agent consisting of a mixture of xanthan gum and guar gum, and
- de l'eau, caractérisée en ce que le rapport gomme xanthane sur gomme guar est d'au moins 1/1 , avantageusement au moins 1 ,5/1 , de préférence d'au moins 4/1.- Water, characterized in that the ratio of xanthan gum to guar gum is at least 1/1, advantageously at least 1.5 / 1, preferably at least 4/1.
Des rapports particulièrement préférés sont de l'ordre de 80/20 à 90/10, des quantités trop élevées de gomme guar étant à l'origine de la formation de grumeaux de colorant à la surface du linge. Des résultats très intéressants sont obtenus lorsque l'on ajoute à la gomme xanthane et éventuellement la gomme guar, de la cellulose ou un dérivé de cellulose, notamment la carboxyméthyl-cellulose.Particularly preferred ratios are of the order of 80/20 to 90/10, excessively high amounts of guar gum being at the origin of the formation of lumps of dye on the surface of the laundry. Very interesting results are obtained when adding to xanthan gum and optionally guar gum, cellulose or a cellulose derivative, in particular carboxymethyl cellulose.
La viscosité (mesurée sur un appareil Broo field avec le mobile 64 à une vitesse de 25 tours/min) de la composition de teinture en gel de l'invention est généralement d'au moins 0,5 Pa.s, avantageusement d'au moins 1 ,5 Pa.s et d'au plus 30 Pa.s, avantageusement au plus 20 Pa.s, viscosité diminuant de façon substantielle en fonction du taux de cisaillement appliqué, notamment lors de l'agitation du récipient de conditionnement de la composition de teinture. Les compositions liquides de teintures utilisées pour l'invention sont tous types de teintures aqueuses telles qu'elles sont obtenues par mélange de colorants disponibles auprès des fournisseurs de matières colorantes.The viscosity (measured on a Broo field device with the mobile 64 at a speed of 25 rpm) of the gel dye composition of the invention is generally at least 0.5 Pa.s, advantageously at least minus 1.5 Pa.s and at most 30 Pa.s, advantageously at most 20 Pa.s, viscosity decreasing substantially depending on the shear rate applied, in particular when the packaging container for the tincture composition. The liquid dye compositions used for the invention are all types of aqueous dyes as they are obtained by mixing dyes available from suppliers of dyestuffs.
On peut citer en particulier les teintures obtenues par mélange de 2 ou plusieurs colorants, de type vinyisulfone, par exemple du bleu brillant REMAZOL® R LIQUIDE 50% dans des proportions variables.Mention may in particular be made of the dyes obtained by mixing 2 or more dyes, of the vinyisulfone type, for example brilliant blue REMAZOL® R LIQUID 50% in variable proportions.
Il est également souhaitable pour une bonne conservation de la teinture en gel de l'invention d'ajouter dans la composition précitée un conservateur ; un exemple de conservateur pouvant convenir est l'octylisothiazolinone commercialisé sous la dénomination MERGAL K9N.It is also desirable for good preservation of the gel dye of the invention to add a preservative to the above composition; an example of a preservative which may be suitable is octylisothiazolinone marketed under the name MERGAL K9N.
Avantageusement, on ajoute la gomme xanthane ou la combinaison de gomme xanthane et de gomme guar sous forme de poudre directement dans le récipient de conditionnement de la composition de teinture. Il n'est pas nécessaire d'avoir recours à une agitation mécanique poussée pour assurer la dissolution de la gomme, la seule manipulation du moyen de conditionnement en vue de sa fermeture étant suffisante, pour assurer une répartition homogène de la gomme au sein de la formulation de teinture.Advantageously, the xanthan gum or the combination of xanthan gum and guar gum in powder form is added directly to the container for packaging the dye composition. It is not necessary to have recourse to extensive mechanical stirring to ensure the dissolution of the gum, the only manipulation of the packaging means with a view to closing it being sufficient, to ensure a homogeneous distribution of the gum within the dye formulation.
Après fermeture du moyen de conditionnement contenant la formulation de l'invention, on laisse celui-ci au repos pour que la prise en gel ait lieu jusqu'à la viscosité finale souhaitée.After closing the packaging means containing the formulation of the invention, it is left to stand so that the gel setting takes place until the desired final viscosity.
La durée optimale pour réaliser un gel présentant une viscosité satisfaisante est d'environ une semaine.The optimal time to make a gel with a satisfactory viscosity is about a week.
Dans un mode de réalisation particulièrement avantageux, la composition de teinture de l'invention est conditionnée dans une barquette en un matériau synthétique, munie d'un opercule, ledit opercule présentant un orifice fermé par un moyen de fermeture amovible lequel est retiré lors de l'utilisation de ladite composition par l'utilisation finale.In a particularly advantageous embodiment, the dye composition of the invention is packaged in a tray made of a synthetic material, provided with a cover, said cover having an orifice closed by a removable closure means which is removed during the use of said composition by end use.
La barquette de conditionnement peut être de forme rectangulaire, carrée, ronde ou ovale.The packaging tray can be rectangular, square, round or oval.
Les dimensions de la barquette sont prévues de manière à ce la superficie de composition liquide soit relativement importante pour assurer une bonne absorption de la gomme xanthane après addition de celle-ci à la composition de teinture.The dimensions of the tray are provided so that the surface area of the liquid composition is relatively large to ensure good absorption of the xanthan gum after addition thereof to the dye composition.
Avantageusement, les dimensions de la barquette sont telles que le rapport superficie de la barquette/profondeur est supérieur à 100, de préférence supérieur à 150. Ainsi, pour un volume final de composition de teinture de 40 à 57 ml, les dimensions de la barquette sont avantageusement de 106 mm x 57 mm x 19 mm.Advantageously, the dimensions of the tray are such that the ratio of the area of the tray / depth is greater than 100, preferably greater than 150. Thus, for a final volume of dye composition of 40 to 57 ml, the dimensions of the tray are advantageously 106 mm x 57 mm x 19 mm.
Pour un volume final de composition de teinture de 75 à 95 ml, les dimensions de la barquette sont avantageusement de 106 mm x 57mm x 32 mm.For a final volume of dye composition of 75 to 95 ml, the dimensions of the tray are advantageously 106 mm x 57 mm x 32 mm.
On décrira ci-après un mode de réalisation particulier du conditionnement selon l'invention, en se référant aux figures jointes sur lesquelles : - la figure 1 représente une vue en perspective d'un ensemble comprenant une barquette selon l'invention telle qu'elle apparaît après remplissage par la composition de teinture, gélification et fermeture du moyen de conditionnement ; - la figure 2 représente une vue en perspective d'un ensemble comprenant une barquette selon l'invention telle qu'elle apparaît lors de l'ouverture du moyen de conditionnement.A particular embodiment of the packaging according to the invention will be described below, with reference to the attached figures in which: - Figure 1 shows a perspective view of an assembly comprising a tray according to the invention as it appears after filling with the dye composition, gelation and closure of the packaging means; - Figure 2 shows a perspective view of an assembly comprising a tray according to the invention as it appears when opening the packaging means.
L'ensemble 1 représenté à la figure 1 comprend une barquette 2 fermé par un opercule 3 thermoscellé sur un rebord supérieur 4 périphérique de la barquette 2.The assembly 1 shown in FIG. 1 comprises a tray 2 closed by a seal 3 heat-sealed on an upper rim 4 peripheral to the tray 2.
La barquette 2 rigide est réalisée avantageusement en un matériau plastique synthétique, par exemple en PVC, l'opercule 3 souple est de préférence réalisé en un matériau plastique synthétique, par exemple en PVC/PE. Une ligne de moindre résistance 5 circulaire est ménagée dans l'opercule 3 à distance de son bord périphérique.The rigid tray 2 is advantageously made of a synthetic plastic material, for example PVC, the flexible cover 3 is preferably made of a synthetic plastic material, for example PVC / PE. A line of circular resistance of least resistance 5 is formed in the cover 3 at a distance from its peripheral edge.
Un moyen de fermeture amovible 6 sous forme d'un panneau adhésif autocollant est disposé sur l'opercule 3.A removable closure means 6 in the form of a self-adhesive adhesive panel is disposed on the cover 3.
Le panneau adhésif 6 a une forme rectangulaire munie au niveau d'un de ses coins d'une languette 7 de saisie.The adhesive panel 6 has a rectangular shape provided at one of its corners with a gripping tab 7.
Le panneau adhésif 6 recouvre la région circulaire 8 de l'opercule 3 délimitée par la ligne 5.The adhesive panel 6 covers the circular region 8 of the cover 3 delimited by the line 5.
Le récipient 1 contient une composition de teinture en gel telle que définie précédemment. Pour pouvoir libérer la composition du récipient, on saisit la languette 7 pour décoller le panneau 6 comme illustré par la figure 2. Le décollement provoque la rupture de l'opercule 3 le long de la ligne 5 et l'enlèvement de sa région 8 qui reste collée au panneau 6. Une ouverture circulaire est alors libérée dans l'opercule 3. On peut alors, par exemple, disposer le récipient 1 dans le tambour d'une machine à laver. Lors d'un cycle de lavage, la composition en gel va être distribuée à l'extérieur du récipient 1 pour remplir sa fonction de teinture textile. L'invention a également pour objet un procédé pour teindre un textile dans une machine à laver le linge, au moyen d'une teinture contenant du colorant réactif, notamment pour teindre des fibres cellulosiques, caractérisé en ce que l'on introduit le textile à teindre dans la cuve d'une machine à laver le linge, et que l'on ajoute un ensemble tel que défini précédemment après ouverture du moyen de fermeture amovible prévu dans l'opercule de fermeture.The container 1 contains a gel dye composition as defined above. In order to be able to release the composition from the container, the tab 7 is grasped in order to peel off the panel 6 as illustrated in FIG. 2. The peeling causes the rupture of the cover 3 along the line 5 and the removal of its region 8 which remains glued to the panel 6. A circular opening is then released in the cover 3. It is then possible, for example, to place the container 1 in the drum of a washing machine. During a washing cycle, the gel composition will be distributed outside the container 1 to fulfill its function of textile dyeing. The invention also relates to a process for dyeing a textile in a washing machine, using a dye containing reactive dye, in particular for dyeing cellulose fibers, characterized in that the textile is introduced dyeing in the tank of a washing machine, and adding an assembly as defined above after opening the removable closure means provided in the closure seal.
