The fabric is moved through the dye bath at least once by a drive roller (3) and a guide roller (4). The fabric is moved through one or more dyes. After passing through a mangle, the fabric is stretched on a stenter frame.

Description

L'invention se rattache au secteur technique des procédés et moyens pour la teinture d'une pièce de tissu, afin d'obtenir une pluralité de dégradés de couleurs, avec des effets visuels variables.The invention relates to the technical sector of methods and means for dyeing a piece of fabric, in order to obtain a plurality of color gradients, with variable visual effects.

D'une manière connue, la pièce de tissu, de couleur écrue, est mouillée, tandis qu'un opérateur applique, manuellement, par tout moyen connu, différentes couleurs pour obtenir un effet visuel quelconque. Cette méthode est donc essentiellement manuelle et les résultats obtenus aléatoires, étant donné qu'ils dépendent directement de l'appréciation et du savoir-faire de l'opérateur. De même, il est difficile de reproduire les effets de couleurs et de dégradés obtenus. Enfin, la pièce de tissu ainsi traitée est d'un coût de revient relativement élevé.In a known manner, the fabric piece, unbleached, is wet, while an operator applies, manually, by any known means, different colors to obtain any visual effect. This method is therefore essentially manual and the results obtained random, since they depend directly on the appreciation and know-how of the operator. Similarly, it is difficult to reproduce the effects of colors and gradients obtained. Finally, the piece of fabric thus treated is a relatively high cost.

Dans les machines de teinture le boyau de tissu est entrainé par un tourniquet dans un bain de colorant uniforme (voir par exemple GB-A-422825 ).In dyeing machines the fabric hose is driven by a tourniquet into a uniform dye bath (see for example GB-A-422825 ).

On a proposé également des solutions techniques permettant d'obtenir, en continu, d'une manière industrielle, un tissu présentant des effets de dégradés de couleurs. On peut citer, par exemple, l'enseignement du brevet FR 2.682.130 dont le demandeur de la présente est également titulaire. Selon cette solution, la pièce de tissu est accrochée sur une ossature support pour être trempée selon différentes hauteurs et selon différentes orientations angulaires, pendant des temps déterminés dans une ou des cuves contenant des colorants. Cette solution permet de tremper la pièce de tissu, partiellement, de lisière en lisière.Technical solutions have also been proposed for continuously obtaining, in an industrial manner, a fabric having color gradient effects. For example, the teaching of FR 2,682,131 which the applicant hereby also holds. According to this solution, the piece of fabric is hooked on a support frame to be soaked in different heights and in different angular orientations, for determined times in a vessel or tanks containing dyes. This solution makes it possible to soak the piece of fabric, partially, from edge to edge.

Le demandeur de la présente a également proposé une autre solution qui permet de traiter le tissu dans la totalité de sa longueur, avec pour objectif d'obtenir une pluralité d'effets de coloris et d'effets visuels du type « ombré cascade », « ombré batik » et différentes combinaisons. Une telle solution ressort de l'enseignement du brevet FR-A-2816962 , selon laquelle :

  • on dispose une longueur de tissu sur un support présentant des agencements pour positionner à volonté le tissu selon différents niveaux décalés en hauteur, d'une manière ordonnée ou non, dans un même plan ou selon des plans différents, lesdits niveaux étant réalisés sur la longueur du tissu ;
  • on mouille ou non, en totalité ou en partie, le tissu ;
  • on trempe successivement l'ensemble du support et du tissu dans des bains de différentes couleurs et selon différentes hauteurs ;
  • pour chacun des trempages et en fonction des effets et/ou dégradés de coloris recherchés, on oriente angulairement le support.
The applicant of the present has also proposed another solution which makes it possible to treat the fabric in all of its length, with the objective of obtaining a plurality of effects of colors and visual effects of the "shaded cascade" type. shaded batik "and different combinations. Such a solution spring from the teaching of FR-A-2816962 , according to which:
  • a length of fabric is arranged on a support having arrangements for positioning the fabric at will according to different levels offset in height, in an ordered manner or not, in the same plane or in different planes, said levels being made along the length fabric ;
  • Wet or not, in whole or in part, the tissue;
  • the support and the fabric are successively dipped in baths of different colors and at different heights;
  • for each of the dipping and depending on the effects and / or color gradient sought, angularly oriented support.

L'invention se propose de mettre en oeuvre un procédé permettant de résoudre le problème posé d'obtenir, sur une pièce de tissu quelconque, des effets de couleurs, de dégradés de couleurs, de mélanges de couleurs avec, notamment, des reflets moirés, des effets de flammes, en ayant pour objectif de traiter ce tissu selon des cadences élevées, de manière à diminuer les coûts de production.The invention proposes to implement a method making it possible to solve the problem of obtaining, on a piece of any fabric, effects of colors, of color gradations, of color mixtures with, in particular, moire reflections, flame effects, with the aim of treating this fabric at high speeds, so as to reduce production costs.

Pour résoudre un tel problème, notamment pour obtenir des reflets moirés et des effets de flammes, il a été conçu et mis au point un procédé selon la revendication 1.To solve such a problem, especially to obtain moire reflections and flame effects, it was designed and developed a method according to claim 1.

Pour résoudre le problème posé d'augmenter les effets visuels, après avoir formé sensiblement un boyau, on réalise des opérations de vrillage et/ou de réserves de couleurs.To solve the problem posed to increase the visual effects, after substantially forming a hose, it performs twisting operations and / or color reserves.

Un autre procédé selon l'invention est décrit dans la revendication 2, dans lequel, selon les colorants sélectionnés, il n'est pas nécessaire de procéder, à chaque changement de colorant, à l'opération de vidange.Another method according to the invention is described in claim 2, wherein, according to the selected dyes, it is not necessary to proceed, at each dye change, to the emptying operation.

Pour résoudre le problème posé de concentrer l'impression, pendant l'opération de trempage et d'entraînement, la largeur du boyau est maintenue sensiblement constante.To solve the problem of concentrating printing, during the soaking and driving operation, the width of the hose is kept substantially constant.

Selon les caractéristiques à la base de l'invention, il est possible de traiter une ou plusieurs pièces de tissu à la fois.According to the characteristics underlying the invention, it is possible to treat one or more pieces of fabric at a time.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :

  • la figure 1 est une vue en coupe longitudinale, à caractère schématique, d'un exemple de réalisation des moyens de mise en oeuvre du procédé de traitement selon l'invention ;
  • la figure 2 est une vue en coupe transversale considérée selon la ligne 2-2 de la figure 1 ;
  • la figure 3 est une vue semblable à la figure 2 montrant le traitement simultané de plusieurs pièces de tissu ;
  • la figure 4 est un exemple d'un échantillon de tissu obtenu selon le procédé de l'invention.
The invention is described below in more detail with reference to the figures of the accompanying drawings, in which:
  • Figure 1 is a longitudinal sectional view, schematic, of an embodiment of the implementation means of the treatment method according to the invention;
  • Figure 2 is a cross-sectional view taken along the line 2-2 of Figure 1;
  • Figure 3 is a view similar to Figure 2 showing the simultaneous processing of several pieces of fabric;
  • Figure 4 is an example of a tissue sample obtained according to the method of the invention.

Selon le procédé de l'invention, on part d'une pièce de tissu quelconque (1), de préférence écrue, sans pour cela exclure le fait que la pièce de tissu (1) puisse préalablement être colorée. La pièce de tissu (1) peut être réalisée dans différentes matières et présente, d'une manière classique, deux lisières parallèles. A titre indicatif, nullement limitatif, la pièce de tissu (1) peut être du velours viscose, de la mousseline soie, ...According to the method of the invention, it starts from a piece of any fabric (1), preferably ecru, without excluding the fact that the piece of cloth (1) can be previously colored. The piece of fabric (1) can be made of different materials and has, in a conventional manner, two parallel edges. As an indication, in no way limiting, the piece of fabric (1) may be viscose velvet, silk chiffon, ...

Selon une caractéristique à la base de l'invention, la pièce de tissu (1) est soumise successivement à l'effet de plusieurs colorants, en ayant pour objectif de faire plaquer le colorant en opposition aux solutions techniques employées pour faire de l'uni, et selon lesquelles on cherche à appliquer, de manière parfaitement uniforme, le colorant sur l'ensemble de la pièce de tissu, avec un effet d'unicité.According to a feature underlying the invention, the piece of fabric (1) is successively subjected to the effect of several dyes, with the objective of having the dye plated in opposition to the technical solutions used to make the plain and according to which it is sought to apply, in a perfectly uniform manner, the dye on the whole of the piece of fabric, with an effect of uniqueness.

Selon l'invention, le tissu (1) est traité d'une manière dynamique pour augmenter les effets visuels recherchés, comme indiqué dans la suite de la description, notamment pour obtenir des reflets moirés et des effets de flammes.According to the invention, the fabric (1) is treated in a dynamic manner to increase the desired visual effects, as indicated in the following description, in particular to obtain moire reflections and flame effects.

D'une manière générale, les deux lisières de la pièce de tissu (1) sont rapprochées de manière à former sensiblement un boyau (la). Le boyau ainsi formé est ensuite trempé successivement dans différents bains de colorant (C) portés à une température déterminée pour faire plaquer, comme indiqué, le colorant. Après voir soumis le boyau à l'action de différents bains de colorants sélectionnés, d'une manière classique, la pièce de tissu est passée à la rame, après avoir été préalablement soumise à une opération d'essorage. Eventuellement, le boyau pourrait être soumis à l'action d'un seul bain de colorant.In general, the two edges of the piece of fabric (1) are brought together so as to substantially form a hose (la). The casing thus formed is then quenched successively in various dye baths (C) brought to a predetermined temperature to cause the dye to be plated as indicated. After subjecting the casing to the action of various dye baths selected, in a conventional manner, the piece of fabric is reamed after having been previously subjected to a wringing operation. Optionally, the casing could be subjected to the action of a single dye bath.

Selon une réalisation préférée dans le cas d'un traitement dynamique de la pièce de tissu, les extrémités du boyau (1a) sont accouplées temporairement, de manière à former une boucle fermée, que l'on entraîne linéairement, à chaque trempage, dans le bain de colorant considéré, en faisant au moins un tour correspondant à la longueur de la pièce de tissu à traiter. Par exemple, dans une forme de réalisation, donnée à titre indicatif, nullement limitatif, la pièce de tissu (1), après avoir été conditionnée sensiblement en boyau, est montée dans une machine connue par l'homme du métier dans le domaine de la teinture, sous le nom de « barque de teinture à tourniquet ».According to a preferred embodiment in the case of a dynamic treatment of the piece of fabric, the ends of the casing (1a) are coupled temporarily, so as to form a closed loop, which is driven linearly, with each dipping, in the dye bath considered, making at least one turn corresponding to the length of the piece of fabric to treat. For example, in one embodiment, given as an indication, in no way limiting, the piece of fabric (1), after having been conditioned substantially in gut, is mounted in a machine known to those skilled in the field of dyeing, under the name of "turnstile dyeing boat".

Comme le montre la figure 2, la machine comprend essentiellement un bac de réserve d'eau (2) délimitant notamment deux flasques parallèles (2a) et (2b).As shown in Figure 2, the machine essentially comprises a water reserve tank (2) defining in particular two parallel flanges (2a) and (2b).

Entre les deux flasques (2a) et (2b) est montée un tambour d'entraînement en rotation (3) assujetti par exemple à un moteur pour être entraîné positivement en rotation. Un rouleau (4) est monté en rotation entre les deux flasques (2a) et (2b), ledit rouleau (4) étant généralement situé à un niveau inférieur par rapport à celui du tambour d'entraînement (3).Between the two flanges (2a) and (2b) is mounted a rotary drive drum (3) secured for example to a motor to be driven positively in rotation. A roller (4) is rotatably mounted between the two flanges (2a) and (2b), said roller (4) being generally located at a lower level than that of the driving drum (3).

La pièce de tissu (1), conditionnée en boyau (1a) est monté entre l'organe (3) et le rouleau (4), après avoir été conditionné sous forme de boucle résultant de l'accouplement temporaire des deux extrémités libres. L'ensemble du bac (2) est asservi à un moyen d'alimentation en eau et à un moyen de vidange. Le moyen d'alimentation en eau est par ailleurs combiné avec tout organe permettant de porter l'eau à une température désirée. Ces différents moyens de mise en oeuvre ne sont pas décrits en détail, car parfaitement connus pour un homme du métier.The piece of fabric (1), packaged in gut (1a) is mounted between the member (3) and the roller (4), having been conditioned in the form of a loop resulting from the temporary coupling of the two free ends. The entire tank (2) is slaved to a water supply means and a draining means. The water supply means is also combined with any member for bringing the water to a desired temperature. These various means of implementation are not described in detail because they are well known to those skilled in the art.

Selon le procédé de l'invention, le fond du bac (2) est rempli d'eau selon un niveau déterminé, pour assurer le trempage de la pièce de tissu (1) qui, à ce niveau, est plus ou moins repliée sur elle-même en fonction de la distance séparant l'organe d'entraînement (3) et le rouleau de renvoi (4).According to the method of the invention, the bottom of the tank (2) is filled with water to a predetermined level, to ensure the soaking of the piece of cloth (1) which, at this level, is more or less folded back on itself as a function of the distance separating the drive member (3) and the return roller (4).

L'eau est portée à une température sensiblement d'ébullition. Par exemple, l'eau est portée à une température d'environ 80°C.The water is brought to a substantially boiling temperature. For example, the water is heated to a temperature of about 80 ° C.

On verse ensuite un premier colorant (C), qui vient naturellement se mélanger avec l'eau, de manière à constituer un bain de colorant à température souhaitée. A noter que, pour faciliter le mélange du colorant, ce dernier peut être versé dans une réserve (2c) que présente le fond du bac délimité par une grille verticale (5).A first dye (C) is then poured, which is naturally mixed with the water so as to form a dye bath at the desired temperature. Note that, to facilitate the mixing of the dye, the latter can be poured into a reserve (2c) that has the bottom of the tray defined by a vertical grid (5).

Sous l'effet de l'entraînement, la totalité de la longueur de la pièce de tissu est soumise à l'action du bain de colorant (C). Le boyau est entraîné sur au moins un tour, de manière à soumettre la totalité de la longueur du boyau à au moins une fois l'action du colorant. D'une manière préférée, le boyau est entraîné selon au moins deux ou trois tours.Under the effect of the drive, the entire length of the piece of fabric is subjected to the action of the dye bath (C). The casing is driven over at least one turn, so as to subject the entire length of the casing to at least once the action of the dye. In a preferred manner, the hose is driven in at least two or three turns.

La température du bain de colorant est particulièrement importante pour plaquer ledit colorant d'une manière aléatoire. Le tissu est donc soumis à l'action du bain du colorant dont la température est déterminée pour permettre son plaquage en opposition aux techniques de teinture connues, selon lesquelles la température du bain est progressivement élevée, pour permettre une parfaite répartition uniforme du colorant sur l'ensemble de la pièce de tissu.The temperature of the dye bath is particularly important for tacking said dye in a random manner. The fabric is therefore subjected to the action of the dye bath whose temperature is determined to allow its plating in opposition to known dyeing techniques, according to which the bath temperature is gradually raised, to allow a perfect uniform distribution of the dye on the surface. whole piece of fabric.

Après avoir soumis, dans les conditions indiquées, la pièce de tissu à l'action d'un premier colorant, le bac (2) est vidangé pour recevoir un second bain de colorant porté à la même température que celle précédemment sélectionnée ou à une température différente. A noter que la sélection de la température dépend notamment de la nature de la pièce de tissu à traiter et de la nature du colorant notamment. Par exemple, dans le cas d'un tissu mousseline soie, le colorant peut être mélangé avec de l'acide, dans le cas d'un tissu en viscose, le colorant peut être mélangé avec du sel.After having subjected, under the conditions indicated, the piece of fabric to the action of a first dye, the tray (2) is emptied to receive a second dye bath heated to the same temperature as the one previously selected or at a temperature different. Note that the selection of the temperature depends in particular on the nature of the piece of fabric to be treated and the nature of the dye in particular. For example, in the case of silk chiffon fabric, the colorant may be mixed with acid, in the case of viscose fabric the colorant may be mixed with salt.

Compte tenu des caractéristiques à la base du procédé selon l'invention, le tissu peut être soumis, dans les conditions indiquées, à l'action de quatre colorants différents par exemple. On observe également qu'en fonction du colorant sélectionné, il peut ne pas être nécessaire de vidanger le bac pour la mise en place d'un nouveau colorant.Given the characteristics underlying the process according to the invention, the fabric can be subjected, under the conditions indicated, to the action of four different dyes for example. It is also observed that depending on the selected dye, it may not be necessary to drain the tray for the introduction of a new dye.

Comme le montre la figure 3, il est possible de traiter une seule pièce de tissu ou bien, comme le montre la figure 4, teinter simultanément, sur la même machine, plusieurs pièces de tissu.As shown in Figure 3, it is possible to treat a single piece of fabric or, as shown in Figure 4, tint simultaneously, on the same machine, several pieces of fabric.

A noter que la machine peut présenter des agencements permettant de maintenir, sensiblement constante, la largeur du boyau pendant l'opération de trempage et d'entraînement. Par exemple, le boyau peut être engagé entre deux guides parallèles.Note that the machine may have arrangements for maintaining, substantially constant, the width of the hose during the soaking and driving operation. For example, the hose can be engaged between two parallel guides.

En ayant toujours pour objectif d'augmenter les effets visuels, préalablement à l'opération de teinture en tant que telle, ou éventuellement pendant certaines phases de cette opération, le boyau peut être soumis à des opérations de vrillage plus ou moins serrées et/ou à des opérations aptes à créer des réserves de couleurs.Always aiming to increase the visual effects, prior to the dyeing operation as such, or possibly during certain phases of this operation, the hose may be subjected to twisting operations more or less tight and / or operations capable of creating color reserves.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle la possibilité d'obtenir des reflets moirés, des effets de flammes, en combinaison avec des dégradés et/ou mélanges de couleurs et selon des cadences de traitement élevées, permettant de diminuer les coûts.The advantages are apparent from the description, in particular, the possibility of obtaining moire reflections, flame effects, in combination with gradients and / or color mixtures and at high processing speeds, which can be used. reduce costs.
