Description

DISPOSITIF D "USURE ET DE DÉCOLORATION ARTIFICIELLES DE PRODUITS TEXTILES ARTIFICIAL WEAR AND DECOLORATION DEVICE FOR TEXTILE PRODUCTS
La présente invention concerne les dispositifs d'usure ou de vieillis¬ sement artificiel intéressant l'industrie textile, notamment celle de l'ha¬ billement, plus particulièrement l'industrie du prêt à porter, notamment le vêtement confectionné avec de la toile teintée. On sait que les vêtements confectionnés avec de la toile teintée comme la toile "Jean" par exemple, sont des vêtements dont la couleur relativement sombre et la toile généralement épaisse et donc peu souple, les rendent peu attrayants et peu aisés à porter en sortie des usines de fabrication sans traitement supplémentaire. De plus, la mode actuelle et la demande du consommateur s'orien¬ tent vers des vêtements de couleurs plutôt claires, peu austères, présen¬ tant un aspect "usé" ou de "déjà porté", dès l'achat. Pour obtenir de tels produits rapidement suivant des procédés compatibles avec des exi¬ gences économiques, l'art antérieur nous enseigne notamment un procé- dé et une machine de traitement d'usure suivant la description ci-des¬ sous.The present invention relates to devices worn or artificial vieillis¬ ment of interest to the textile industry, including that of ha¬ billement, especially the lending industry to wear, including clothing made with the dyed fabric. We know that clothes made with tinted canvas like "Jean" canvas for example, are clothes whose relatively dark color and the canvas generally thick and therefore not very flexible, make them unattractive and not very easy to wear when leaving manufacturing plants without further processing. In addition, current fashion and consumer demand are moving towards clothes of rather light colors, not very austere, presenting a "worn" or "already worn" appearance, from the time of purchase. To obtain such products quickly according to methods compatible with economic requirements, the prior art teaches us in particular a process and a wear treatment machine according to the description below.
Les vêtements à traiter sont introduits dans un tambour de machine rotative dont les parois intérieures sont munies d'un revêtement caout¬ chouté amortisseur et, avantageusement, de bossages, avec au moins de l'eau et une certaine quantité de pierre ponce remplissant la fonction d'abrasif dans le procédé d'usure. Le tambour, après avoir été fermé, est mis en rotation suivant un cycle déterminé, pendant lequel les vête¬ ments brassés au contact de la pierre ponce, s'usent selon un degré dé¬ terminé notamment par le cycle de rotations, les bossages ayant fonction d'éviter la mise en boule des vêtements pendant les rotations.The garments to be treated are introduced into a drum of a rotary machine, the internal walls of which are provided with a damped rubberized coating and, advantageously, bosses, with at least water and a certain quantity of pumice stone fulfilling the function. abrasive in the wear process. The drum, after having been closed, is rotated according to a determined cycle, during which the clothes brewed in contact with the pumice stone wear out to a degree determined in particular by the cycle of rotations, the bosses having function of avoiding curling of clothes during spins.
L'utilisation de cette méthode amène à respecter certaines valeurs dans les quantités des différents éléments en présence, pour une qualité de produits donnée, et limite les durées de vie de certaines parties des machines, c'est notamment le cas du revêtement caoutchouté qui doit être changé fréquemment. A titre indicatif, les valeurs moyennes em¬ ployées sont de l'ordre de 1 kilogramme de pierre ponce pour 1 kilo¬ gramme de vêtements à traiter, ce qui induit le rejet d'environ 100 kilo¬ grammes de boues de pierre ponce pour 100 kilogrammes de vêtements traités. La durée moyenne d'un traitement dans de telles machines étant de 105 mn environ, on peut constater que la quantité de boues à rejeter est énorme, ce qui pose nécessairement des problèmes de pollution, avec tous les coûts supplémentaires que cela entraîne notamment avec l'in¬ stallation de stations de traitement des rejets. De plus, le brassage de la pierre ponce dans le tambour provoque un bruit élevé et donc une nui¬ sance pour les opérateurs travaillant dans l'environnement des ma¬ chines. On peut noter encore que le remplacement du revêtement caout¬ chouté demande quelques jours d'immobilisation de la machine, pendant lesquels celle-ci n'est plus productive. L'ensemble de ces remarques re- présente un certain nombre d'inconvénients loin d'être négligeables.The use of this method leads to respecting certain values in the quantities of the different elements present, for a given product quality, and limits the lifetimes of certain parts of the machines, this is particularly the case of the rubberized coating which must be changed frequently. As an indication, the average values used are of the order of 1 kilogram of pumice stone for 1 kilo¬ gram of clothing to be treated, which induces the rejection of approximately 100 kilo¬ grams of pumice mud for 100 kilograms of treated clothing. The average duration of treatment in such machines being About 105 minutes, it can be seen that the quantity of sludge to be discharged is enormous, which necessarily poses pollution problems, with all the additional costs that this entails in particular with the installation of waste treatment stations. In addition, the mixing of pumice stone in the drum causes a high noise and therefore a nuisance for operators working in the environment of machines. It may also be noted that the replacement of the rubberized coating requires a few days of immobilization of the machine, during which the latter is no longer productive. All of these remarks represent a certain number of disadvantages far from being negligible.
La présente invention permet de pallier notamment les différents in¬ convénients cités ci-dessus et d'apporter d'autres avantages que nous développerons dans les paragraphes qui suivent.The present invention overcomes in particular the various disadvantages mentioned above and provides other advantages which we will develop in the following paragraphs.
Plus précisément, l'invention a pour objet un dispositif permettant d'obtenir artificiellement une usure et une décoloration de produits en matière textile, comprenant au moins une enceinte, ladite enceinte étant constituée par un tambour apte à être mû en rotation autour d'un axe, ledit tambour possédant une ouverture munie d'une porte étanche d'accès, les parois intérieures dudit tambour étant munies au moins en partie d'au moins un revêtement abrasif, caractérisé en ce que ledit re¬ vêtement abrasif comprend au moins des particules saillantes et au moins un liant desdites particules.More specifically, the subject of the invention is a device making it possible to artificially obtain wear and discoloration of textile products, comprising at least one enclosure, said enclosure being constituted by a drum capable of being moved in rotation around a axis, said drum having an opening provided with a sealed access door, the interior walls of said drum being provided at least in part with at least one abrasive coating, characterized in that said abrasive coating comprises at least particles protrusions and at least one binder of said particles.
On peut avantageusement constater que le dispositif selon l'inven¬ tion, permet principalement de réaliser un frottement répétitif des vête- ments sur le revêtement abrasif munie de particules saillantes équipant l'intérieur de l'enceinte, et permet de ce fait de supprimer l'emploi de la pierre ponce ainsi qu'évidemment tous les inconvénients liés à l'usage de celle-ci, comme notamment les problèmes de pollution, de nuisance par le bruit, d'agression mécanique de la machine utilisée, de perte de rendement de traitement dû au volume de pierre ponce non occupé par les produits à traiter, de coût engendré par l'approvisionnement de la pierre ponce et le traitement des boues résiduelles. D'autre part, l'adjonction par exemple dans l'eau, notamment d'enzymes, permet de combiner un traitement de décoloration avec le traitement d'usure. La mise en contact cyclique des produits à traiter avec le revêtement abrasif selon l'invention est obtenue par la rotation de l'enceinte sur elle- même, ce qui peut procurer notamment l'avantage de pouvoir utiliser le dispositif selon l'invention sur les machines industrielles rotatives em- ployées couramment notamment dans l'industrie du traitement des vête¬ ments. On notera à ce sujet que. bien que leur emploi ne soit pas indis¬ pensable, cette caractéristique permet l'introduction d'éléments abrasifs mobiles dans l'enceinte, par exemple de la pierre ponce en faible quanti- té, pour éventuellement réduire davantage les temps de traitement.It can advantageously be seen that the device according to the invention, mainly allows repetitive rubbing of the clothes on the abrasive coating provided with projecting particles equipping the interior of the enclosure, and thus makes it possible to remove the use of pumice stone as well as obviously all the drawbacks linked to the use of it, such as in particular the problems of pollution, nuisance by noise, mechanical attack on the machine used, loss of efficiency of treatment due to the volume of pumice stone not occupied by the products to be treated, cost generated by the supply of pumice stone and the treatment of residual sludge. On the other hand, the addition for example in water, in particular of enzymes, makes it possible to combine a discoloration treatment with the wear treatment. The cyclic contacting of the products to be treated with the abrasive coating according to the invention is obtained by the rotation of the enclosure on itself, which can in particular provide the advantage of being able to use the device according to the invention on the industrial rotary machines em- commonly used in particular in the clothing processing industry. It will be noted on this subject that. although their use is not essential, this characteristic allows the introduction of mobile abrasive elements into the enclosure, for example pumice in small quantities, to possibly further reduce treatment times.
La combinaison d'un liant et de particules saillantes pour former le revêtement abrasif selon l'invention permet d'obtenir des caractéris¬ tiques abrasives et de durée du revêtement suivant les besoins en fonc¬ tion des matériaux composant le liant et les particules. Cette combinai- son autorise à la fois une épaisseur et un poids de revêtement faibles, et une forme géométrique appropriée de ce dernier.The combination of a binder and projecting particles to form the abrasive coating according to the invention makes it possible to obtain abrasive characteristics and duration of the coating according to the needs in function of the materials making up the binder and the particles. This combination allows both a low coating thickness and weight, and an appropriate geometric shape of the latter.
Selon une caractéristique avantageuse, ledit revêtement abrasif forme au moins une surface délimitée, au plus en totalité, par une droite se dé¬ plaçant perpendiculairement audit axe de rotation suivant deux généra- trices desdites parois intérieures. Cette caractéristique permet d'obtenir une usure plus homogène.According to an advantageous characteristic, said abrasive coating forms at least one surface delimited, at most entirely, by a straight line moving perpendicularly to said axis of rotation along two generatrixes of said interior walls. This characteristic makes it possible to obtain a more homogeneous wear.
Selon une autre caractéristique, le revêtement abrasif est placé sur lesdites parois intérieures par des moyens de fixation démontables. On pourra noter ainsi l'aspect technique pratique, notamment pour le rem- placement rapide du revêtement abrasif ou son adaptation éventuelle sur des tambours de machines conventionnelles. Cependant, la nature dé¬ montable du revêtement n'étant pas nécessaire pour le fonctionnement du dispositif selon l'invention, on peut très bien avoir un revêtement abrasif intégré, non démontable, dans le tambour. Une autre caractéristique avantageuse consiste notamment à utiliser un ou des bossages démontables comme moyens de fixation démon¬ tables, ce qui procure une possibilité d'interchangeabilité rapide du re¬ vêtement abrasif, donc une diminution appréciable des délais d'indispo¬ nibilité de la machine dans le cas de cette opération, et une simplicité de conception.According to another characteristic, the abrasive coating is placed on said interior walls by removable fixing means. The practical technical aspect can thus be noted, in particular for the rapid replacement of the abrasive coating or its possible adaptation to drums of conventional machines. However, since the removable nature of the coating is not necessary for the operation of the device according to the invention, it is very possible to have an integrated, non-removable abrasive coating in the drum. Another advantageous characteristic consists in particular in using one or more removable bosses as demon¬ table fixing means, which provides a possibility of rapid interchangeability of the abrasive coating, therefore an appreciable reduction in the unavailability times of the machine. in the case of this operation, and a simplicity of design.
Une autre caractéristique du dispositif suivant l'invention, consiste en ce que ledit revêtement abrasif comprend au moins :Another characteristic of the device according to the invention consists in that said abrasive coating comprises at least:
* une couche stratifiée au moins, comprenant au moins une résine et au moins une substance fibreuse, * une couche supplémentaire au moins, comprenant au moins une résine et au moins des particules saillantes. * at least one laminated layer, comprising at least one resin and at least one fibrous substance, * at least one additional layer, comprising at least one resin and at least projecting particles.
La préférence d'une telle caractéristique réside notamment dans l'obtention d'un revêtement résistant à de fortes contraintes méca- niques, pouvant donc former une structure portante du tambour, ou être soumis à de fortes charges de produits à traiter.The preference for such a characteristic resides in particular in obtaining a coating resistant to high mechanical stresses. nics, which can therefore form a bearing structure of the drum, or be subjected to heavy loads of products to be treated.
Des caractéristiques avantageuses d'un tel revêtement consistent en ce que ladite résine est une résine de polyester ou analogue, ladite sub- stance fibreuse est constituée de fibres de verre ou analogue, par exemple de carbone ou de Kevlar®, lesdites particules saillantes sont constituées de particules abrasives comme le sable de quartz ou analogue. Selon une autre caractéristique, la résine de polyester est préaccélé¬ rée avec un additif, notamment l'octoate de cobalt, contient une silice colloïdale, et est catalysée notamment par du peroxyde de méthyléthyl- cétone, et selon une autre caractéristique lesdites particules abrasives sont concentrées dans ladite couche supplémentaire en raison de 10 à 12 kilogrammes par mètre carré de revêtement, avec une granulomé- trie, comprise entre O et 7 millimètres, et de préférence de l'ordre de 3 millimètres.Advantageous characteristics of such a coating consist in that said resin is a polyester resin or the like, said fibrous substance consists of glass fibers or the like, for example of carbon or Kevlar®, said projecting particles consist abrasive particles such as quartz sand or the like. According to another characteristic, the polyester resin is pre-accelerated with an additive, in particular cobalt octoate, contains colloidal silica, and is catalyzed in particular by methyl ethyl ketone peroxide, and according to another characteristic, said abrasive particles are concentrated in said additional layer at a rate of 10 to 12 kilograms per square meter of coating, with a particle size, between 0 and 7 millimeters, and preferably of the order of 3 millimeters.
L'intérêt recherché dans de telles caractéristiques réside notam¬ ment dans l'obtention d'une résistance du revêtement aux agressions chimiques en cas d'adjonction dans le fluide mouillant d'additifs comme des enzymes. L'intérêt et les nombreux avantages du dispositif selon l'invention ressortiront à la lecture de la description d'un exemple qui suit, accom¬ pagné des dessins annexés, d'un mode de réalisation d'un tel dispositif, exemple donné à titre d'illustration et sans qu'aucune interprétation restrictive de la protection recherchée ne puisse en être tirée. La Figure 1 représente schématiquement en coupe transversale un tambour suivant l'invention, dont les parois intérieures sont munies de bossages et d'un revêtement abrasif, tambour notamment destiné à être monté sur une machine rotative.The interest sought in such characteristics lies in particular in obtaining resistance of the coating to chemical attack in the event of the addition of additives such as enzymes to the wetting fluid. The advantage and the numerous advantages of the device according to the invention will emerge on reading the description of an example which follows, accompanied by the appended drawings, of an embodiment of such a device, example given by way of illustration and without any restrictive interpretation of the protection sought can be drawn from it. Figure 1 shows schematically in cross section a drum according to the invention, the inner walls of which are provided with bosses and an abrasive coating, drum in particular intended to be mounted on a rotary machine.
La Figure 2 représente une coupe dans l'épaisseur d'un exemple de revêtement abrasif, à base de résine, de particules saillantes abrasives, et comportant une couche stratifiée.Figure 2 shows a section through the thickness of an example of an abrasive coating, based on resin, abrasive protruding particles, and comprising a laminated layer.
Le dispositif suivant la Figure 1 est constitué d'un tambour rotatif 1 autour d'un axe 5 et équipé d'une ouverture 6 munie d'une porte étanche d'accès 7. La partie cylindrique des parois intérieures 2 du tam- bour est munie d'un revêtement abrasif 3 avantageusement en trois par¬ ties. Ce revêtement abrasif est ainsi délimité entre quatre bossages 8 d'axe longitudinal sensiblement parallèle à une génératrice des parois cylindriques intérieures 2, les bossages 8 étant de toutes formes connues, d'épaisseurs supérieures à celle du revêtement abrasif 3 et de longueur au plus égale à ladite génératrice. Ces bossages sont destinés à éviter que la charge de vêtements ne forme une boule plus ou moins ho¬ mogène pendant le cycle de rotations, nuisant ainsi à l'aspect final du produit. Un des quatre intervalles de la surface cylindrique intérieure du tambour 1, délimités par deux des bossages 8, n'est pas muni de revête¬ ment abrasif 3, cet intervalle étant occupé par l'ouverture 6 de remplis¬ sage du tambour 1.The device according to FIG. 1 consists of a rotary drum 1 around an axis 5 and equipped with an opening 6 provided with a sealed access door 7. The cylindrical part of the interior walls 2 of the drum is provided with an abrasive coating 3 advantageously in three parts. This abrasive coating is thus delimited between four bosses 8 of longitudinal axis substantially parallel to a generatrix of the internal cylindrical walls 2, the bosses 8 being of any shape. known, of thicknesses greater than that of the abrasive coating 3 and of length at most equal to said generator. These bosses are intended to prevent the load of clothing from forming a more or less homogeneous ball during the rotation cycle, thus harming the final appearance of the product. One of the four intervals of the inner cylindrical surface of the drum 1, delimited by two of the bosses 8, is not provided with an abrasive coating 3, this interval being occupied by the opening 6 for filling the drum 1.
Le revêtement abrasif 3 en trois parties, représenté sur la Figure 1, est avantageusement fixé de manière démontable sur les parois inté¬ rieures 2 du tambour 1 par l'intermédiaire des bossages 8, par emboîte¬ ment entre la paroi intérieure cylindrique 2 et les bossages 8, eux- mêmes fixés de manière démontable par tous moyens connus, par exemple par des boulons, à la paroi du tambour 1. Cette méthode de fixa- tion démontable du revêtement abrasif autorise un remplacement rapide de celui-ci quand il est usé, par dévissage de quelques boulons. On peut également noter une possibilité de transformation rapide de la machine sur laquelle est monté ledit tambour en une machine traditionnelle rota¬ tive, par exemple une machine à laver, par simple démontage du revête- ment abrasif.The abrasive coating 3 in three parts, shown in FIG. 1, is advantageously fixed in a removable manner on the inner walls 2 of the drum 1 by means of the bosses 8, by fitting between the cylindrical inner wall 2 and the bosses 8, themselves detachably attached by any known means, for example by bolts, to the wall of the drum 1. This method of detachable attachment of the abrasive coating allows rapid replacement thereof when it is worn , by unscrewing a few bolts. It is also possible to note a possibility of rapid transformation of the machine on which said drum is mounted into a traditional rotary machine, for example a washing machine, by simple disassembly of the abrasive coating.
Comme le représente la Figure 1 , on relèvera que le revêtement abrasif 3 forme des méplats 9 entre chaque paire de bossages 8 consécu¬ tifs, dont les surfaces sont sensiblement parallèles à l'axe de rotation 5 du tambour 1, et délimitées par une droite se déplaçant perpendiculaire- ment audit axe de rotation 5 suivant deux génératrices desdites parois intérieures 2. Le but recherché par la mise en place de ces méplats 9 est de compléter la fonction des bossages 8 en limitant le roulement des vê¬ tements à l'intérieur du tambour pendant le cycle de rotations, de façon à homogénéiser l'usure et améliorer ainsi l'efficacité du revêtement abrasif 3.As shown in Figure 1, it will be noted that the abrasive coating 3 forms flats 9 between each pair of bosses 8 consécu¬ tives, the surfaces of which are substantially parallel to the axis of rotation 5 of the drum 1, and delimited by a straight line moving perpendicularly to said axis of rotation 5 along two generatrices of said interior walls 2. The aim sought by the placement of these flats 9 is to complete the function of the bosses 8 by limiting the rolling of the clothes inside drum during the rotation cycle, so as to homogenize the wear and thus improve the efficiency of the abrasive coating 3.
L'exemple de revêtement abrasif, représenté sur la Figure 2 com¬ prend dans sa structure générale au moins des particules abrasives 12, dont certaines font saillie, et un liant 13 desdites particules. Ledit revê¬ tement abrasif possède avantageusement au moins une couche stratifiée 20, comprenant une résine de polyester 13 et une tresse de verre 14, une couche supplémentaire 21, comprenant une résine de polyester 13 et des particules de sable de quartz sec 12.The example of an abrasive coating, shown in Figure 2 includes in its general structure at least abrasive particles 12, some of which protrude, and a binder 13 of said particles. Said abrasive coating advantageously has at least one laminated layer 20, comprising a polyester resin 13 and a glass braid 14, an additional layer 21, comprising a polyester resin 13 and particles of dry quartz sand 12.
Le revêtement décrit selon l'exemple suivant la Figure 2, possède enfin au moins une autre couche 22 de résine 13, afin de chausser définitivement les particules abrasives 12 en surface.The coating described according to the example according to Figure 2, has finally at least one other layer 22 of resin 13, in order to permanently put the abrasive particles 12 on the surface.
Le dispositif d'usure et de décoloration suivant l'invention représen¬ té sur la Figure 1 est mise en oeuvre de la manière suivante : * On introduit la charge de vêtements à traiter dans le tambour 1 dont les parois internes 2 sont munies du revêtement abrasif 3 susceptible d'entrer en contact avec lesdits vêtements lorsque le tambour est mis en rotation. Une ouverture 6 a été réalisée à cet effet, avantageusement pla¬ cée sur la paroi sensiblement cylindrique dudit tambour. * On introduit dans le tambour 1 et par l'ouverture 6 une quantité d'eau représentant avantageusement en poids le double du poids de la charge de vêtements. On peut également rajouter une substance comme des en¬ zymes par exemple dans le cas où l'on désire obtenir une décoloration générale des vêtements, notamment pour certains vêtements en toile "jean", cette opération étant complémentaire au traitement d'usure,The wear and discoloration device according to the invention shown in FIG. 1 is implemented in the following manner: * The load of clothes to be treated is introduced into the drum 1 whose internal walls 2 are provided with the coating abrasive 3 capable of coming into contact with said garments when the drum is rotated. An opening 6 has been made for this purpose, advantageously placed on the substantially cylindrical wall of said drum. * A quantity of water is advantageously introduced into the drum 1 and through the opening 6, representing by weight twice the weight of the load of clothing. It is also possible to add a substance such as en¬ zymes for example in the case where it is desired to obtain a general discoloration of the clothing, in particular for certain clothing in "jean" fabric, this operation being complementary to the wear treatment,
* Après la fermeture étanche du tambour 1 , au moyen de la porte étanche 7, celui-ci est mis en rotation suivant un cycle déterminé en fonction notamment du degré d'usure désiré, et plus généralement en fonction du produit que l'on désire obtenir. On remarquera que l'on n'in- troduit aucun produit abrasif mobile par rapport au tambour 1 tel que la pierre ponce par exemple.* After the sealed closure of the drum 1, by means of the sealed door 7, the latter is rotated according to a cycle determined in particular as a function of the desired degree of wear, and more generally as a function of the product which is desired. get. It will be noted that no mobile abrasive product is introduced relative to the drum 1 such as pumice stone for example.
* Une fois le cycle de rotations achevé, on vidange le tambour 1, et on retire de celui-ci la charge de vêtements ainsi traitée.* Once the rotation cycle is complete, the drum 1 is emptied, and the load of clothing thus treated is removed from it.
Le dispositif selon l'invention est réalisé, comme on aura pu le constater, avec des moyens d'application industrielle largement répan¬ dus, notamment ceux concernant la fabrication des plastiques en parti¬ culier stratifiés pour ce qui est de l'exemple du revêtement abrasif selon l'invention décrit, et notamment ceux concernant les machines rotatives à tambour déjà largement utilisées dans l'industrie, notamment dans les traitements d'usure conventionnels de produits textiles à base de toile utilisant la pierre ponce. The device according to the invention is produced, as we will have been able to see, with means of industrial application which are widely available, in particular those relating to the manufacture of plastics, in particular laminates as regards the example of the coating. abrasive according to the invention described, and in particular those relating to rotary drum machines already widely used in industry, in particular in conventional wear treatments of canvas-based textile products using pumice.
