Definitions
- the present invention relates to a method for treating textile articles or articles, produced from woven or knitted fabrics, the treatment being of the mechanical finishing type and intended to modify their structure, for example by increasing the volume, by improving the flexibility, by modifying their surface appearance.
- Yarn producers have proposed yarns made up of continuous filaments with adherent microfilaments, obtained by star or lamellar spinning. The pieces obtained by weaving or knitting such threads are then subjected to a treatment intended to individualize the microfilaments, so that said piece has the flexibility, the feel, the voluminosity corresponding to the unitary microfilaments.
- This individualization of the microfilaments is carried out using suitable chemical treatments in which the matrix ensuring the bonding of the unitary microfilaments, or superficially the interlamellar surface is attacked. It is in particular a treatment with soda when the microfilaments are made of polyester.
- piece will designate all the presentations of woven or knitted fabrics: fabric or knitted fabric which has fallen out of the trade and which is in the form of a strip of very long length, part cut from such a strip or made-up item.
- the aim set by the applicant is to propose a simplified treatment of textile pieces which not only modifies their structure without causing breakages of continuous filaments in the constituent threads of the piece or of the treated article, but also constituent yarns being continuous filaments with adherent microfilaments, realizes the individualization of the microfilaments.
- Said method consists in treating a textile piece, resting on a support grid, said piece being made up in whole or in part of continuous filament yarns with adherent microfilaments by the action of water jets at a pressure of at least 4.10.6Pa, provided what the action of the water jets dissociates the microfilaments.
- the method of the invention makes it possible to obtain a completely reproducible effect, in the case of simple adjustments of the physical conditions: speed of the grid, pressure of the water jets, in particular.
- the support grid moves continuously under several ramps, each comprising a set of high-pressure water jet injection nozzles, the water pressure being identical or different from one ramp to another.
- the part is subjected to the action of jets at increasingly higher pressures.
- the running speed of the part being between 20 and 100 m / min, it is successively subjected to the action of four ramps of water jets at stepped pressures respectively of 4.106 to 20.106Pa.
- Some constituent threads of the part are for example threads composed of filaments with adherent microfilaments obtained by star spinning, each filament having a titer of approximately 2dtex and comprising from 6 to 8 polyester microfilaments from 0.2 to 0.4dtex, assembled using a polyamide matrix.
- the treatment installation 1 which will be described is suitable in particular for textile pieces, fabrics or knits, wound in the form of coils 2 of continuous strips.
- This installation 1 comprises a set of means carrying out the positioning and the transport of the part 3, namely from upstream to downstream a shaft 4, driven by a motor not shown, on which is fitted the coil 2, rollers 5 of tension, a support grid 6 consisting of an endless belt wound and stretched between two cylinders 7,8 driven at the same linear speed as the shaft 4, the part 3 resting on the upper part 6 a of the grid 6, and finally a detour roller 9 cooperating with a shaft 10 for winding the coil 11 consisting of the part 3 treated.
- FIG. 1 shows only two ramps 12, 13 for injecting high pressure water.
- Each ramp is supplied by a pump 14.15 capable of working at adjustable pressures ranging from 4.106Pa (40 bars) to more than 20.106 Pa (200 bars).
- Each ramp 12, 13 comprises a plate pierced with a set of orifices serving as injection nozzles 16 distributed on the one hand over the entire useful width of the grid 6 at the rate of an orifice every 2 mm and of somewhere else on several rows, for example three rows have been shown in FIG. 1.
- the high pressure water leaving the injection nozzles 16 is in the form of extremely fine jets, having a diameter of the order of 100 to 150 micrometers.
- Suction boxes 17,18 are placed opposite the injection ramps 12,13 under the upper part 6 a of the grid 6 while the ramps are located above this upper part 6 a , the nozzles 16 being directed perpendicular to the plane of said upper part 6 a and therefore to part 3.
- the support grid 6 is a metallic grid of 100 mesh (that is to say of 100 meshes per inch) produced with wires of 200 micrometers in diameter.
- a drying tunnel 19 is placed on the passage of the part 3 treated after the outlet cylinder 8 and before the detour roller 9.
- a polyester fabric of about 130 g / m2 has been treated having as warp yarn a conventional yarn making 90 dtex, and comprising 136 continuous filaments, and as weft yarn a continuous filament yarn with adherent microfilaments obtained by star spinning.
- Such a wire is shown in Figure 2A. It comprises six unitary polyester microfilaments; each microfilament 20 has in cross section the shape of an orange quarter; the six microfilaments 20 are separated by a polyamide matrix 21 having six radial branches 22 symmetrically distributed around the longitudinal axis 23.
- Each unitary microfilament 20 of polyester has a titration of between 0.2 and 0.4dtex.
- the treatment of the above fabric was carried out at 20m / min, by passing under four injection ramps, the water being respectively at 6.106Pa, 8.106Pa, 20.106Pa and 20.106Pa.
- the enclosure corresponds to the distribution of the filaments and microfilaments in relation to the volume of the tissue.
- FIGS. 3 and 4 There are other types of son with adherent microfilaments, in particular those shown in FIGS. 3 and 4.
- a coreless wire is shown, that is to say that the bonding matrix of the four microfilaments 24 in polyester is made up of four polyamide 25 microfilaments joined to two successive polyester microfilaments 24.
- FIG. 4 shows a thread of the lamellar type in which the polyester microfilaments 26 correspond to longitudinal sections of a filament of substantially circular section. Self-adhesion between the four microfilaments 26 is obtained due to the fact that when spinning the four strips are joined only after the polyester has cooled down for a certain time.
- the invention is based on the use of water jets at pressures of at least 4.106 Pa (40 bars) to modify the structure of textile pieces, fabrics or knits, whose constituent yarns are already assembled between them.
- This structural modification consists in the mechanical separation and the relative displacement of microfilaments which had, in the thread before treatment and during weaving or knitting, a certain adhesion.

Abstract
Description
La présente invention concerne un procédé de traitement de pièces ou articles textiles , réalisés à partir d'étoffes tissées ou tricotées , le traitement étant du type apprêt mécanique et destiné à modifier leur structure , par exemple en augmentant la voluminosité , en améliorant la souplesse , en modifiant leur aspect de surface.The present invention relates to a method for treating textile articles or articles, produced from woven or knitted fabrics, the treatment being of the mechanical finishing type and intended to modify their structure, for example by increasing the volume, by improving the flexibility, by modifying their surface appearance.
Il existe de très nombreux apprêts mécaniques , dans lesquels des organes divers sont mis en oeuvre , lesdits organes et leur mode d'action étant choisis en fonction du but recherché: chardons , rouleaux de grattage pour donner un aspect pelucheux à une pièce en filés de fibres , machine de foulage pour donner le volume à la laine, tapis vibrant ou autre dispositif de projection mécanique de la pièce sur un obstacle pour améliorer la stabilité dimensionnelle etc... Dans toutes ces techniques , les organes mécaniques entrent en contact avec la pièce textile et modifient lors de ce contact la structure que ladite pièce avait soit après tissage ou tricotage soit éventuellement après confection de l'article fini, le plus souvent par un déplacement relatif des fils constitutifs de la pièce, ou des fibres discontinues ou des filaments continus composant lesdits fils. Dans la plupart des cas ce contact des organes mécaniques s'accompagne d'une certaine dégradation de la pièce par des casses de filaments ou de fibres. D'autre part ce contact entre les pièces et l'organe mécanique peut entraîner une usure de l'organe et donc une évolution progressive du résultat obtenu.There are very many mechanical primers, in which various organs are used, said organs and their mode of action being chosen according to the desired objective: thistles, scraping rollers to give a fluffy appearance to a piece of yarns. fibers, fulling machine to give volume to the wool, vibrating mat or other mechanical device for projecting the part onto an obstacle to improve dimensional stability, etc. In all these techniques, the mechanical organs come into contact with the part textile and modify during this contact the structure that said piece had either after weaving or knitting or possibly after making the finished article, most often by a relative displacement of the constituent threads of the piece, or of staple fibers or continuous filaments composing said wires. In most cases this contact of the mechanical organs is accompanied by a certain degradation of the part by breaking of filaments or fibers. On the other hand, this contact between the parts and the mechanical member can lead to wear of the member and therefore a progressive evolution of the result obtained.
Les producteurs de fils ont proposé des fils constitués de filaments continus à microfilaments adhérents, obtenus par filage en étoile ou lamellaire. Les pièces obtenues en tissant ou en tricotant de tels fils sont ensuite soumises à un traitement destiné à individualiser les microfilaments, de manière à ce que ladite pièce ait la souplesse, le toucher, la voluminosité correspondant aux microfilaments unitaires.Yarn producers have proposed yarns made up of continuous filaments with adherent microfilaments, obtained by star or lamellar spinning. The pieces obtained by weaving or knitting such threads are then subjected to a treatment intended to individualize the microfilaments, so that said piece has the flexibility, the feel, the voluminosity corresponding to the unitary microfilaments.
Cette individualisation des microfilaments est réalisée à l'aide de traitements chimiques adaptés dans lesquels la matrice assurant le collage des microfilaments unitaires, ou superficiellement la surface interlamellaire est attaquée. Il s'agit en particulier de traitement à la soude lorsque les microfilaments sont en polyester.This individualization of the microfilaments is carried out using suitable chemical treatments in which the matrix ensuring the bonding of the unitary microfilaments, or superficially the interlamellar surface is attacked. It is in particular a treatment with soda when the microfilaments are made of polyester.
De tels traitements chimiques présentent de multiples inconvénients : il est difficile de contrôler parfaitement tous les paramètres pour obtenir un traitement uniforme (durée de traitement, température , concentration du bain) ; la pièce ainsi traitée perd du poids du fait de sa dissolution partielle ; les traitements sont longs et onéreux.Such chemical treatments have multiple drawbacks: it is difficult to perfectly control all the parameters in order to obtain a uniform treatment (treatment time, temperature, bath concentration); the part thus treated loses weight due to its partial dissolution; treatments are long and expensive.
Dans la suite du texte , on désignera sous le terme général "pièce" toutes les présentations des étoffes tissées ou tricotées: tissu ou tricot tombé de métier et se présentant sous forme d'une bande de grande longueur, partie découpée d'une telle bande ou article confectionné.In the remainder of the text, the general term "piece" will designate all the presentations of woven or knitted fabrics: fabric or knitted fabric which has fallen out of the trade and which is in the form of a strip of very long length, part cut from such a strip or made-up item.
Le but que s'est fixé le demandeur est de proposer un traitement simplifié de pièces textiles qui non seulement en modifie la structure sans occasionner de casses de filaments continus dans les fils constitutifs de la pièce ou de l'article traité, mais encore , les fils constitutifs étant des filaments continus à microfilaments adhérents, réalise l'individualisation des microfilaments.The aim set by the applicant is to propose a simplified treatment of textile pieces which not only modifies their structure without causing breakages of continuous filaments in the constituent threads of the piece or of the treated article, but also constituent yarns being continuous filaments with adherent microfilaments, realizes the individualization of the microfilaments.
Ce but est parfaitement atteint par le procédé de l'invention . Ledit procédé consiste à traiter une pièce textile, reposant sur une grille support , ladite pièce étant constituée en tout ou partie de fils de filaments continus à microfilaments adhérents par action de jets d'eau à une pression d'au moins 4.10.⁶Pa, moyennant quoi l'action des jets d'eau désolidarise les microfilaments.This object is perfectly achieved by the method of the invention. Said method consists in treating a textile piece, resting on a support grid, said piece being made up in whole or in part of continuous filament yarns with adherent microfilaments by the action of water jets at a pressure of at least 4.10.⁶Pa, provided what the action of the water jets dissociates the microfilaments.
Certes on connaît par les documents EP.A.10.546 et EP.A.193.0378 des traitements de pièces textiles, dans lesquels lesdites pièces sont soumises à l'action de jets de fluide à haute pression.It is certainly known from documents EP.A.10.546 and EP.A.193.0378 of treatments of textile parts, in which said parts are subjected to the action of jets of fluid at high pressure.
Dans le document EP.A.193.078, l'action des jets d'eau vise à rendre plus ouverte la structure fibreuse d'un tissu de fibres inorganiques pour le renforcement de résine, notamment pour les plaques de circuits imprimés.In document EP.A.193.078, the action of the water jets aims to make the fibrous structure of a fabric of inorganic fibers more open for the reinforcement of resin, in particular for printed circuit boards.
Dans le document EP.A.10.546 l'action des jets d'eau a pour but de donner à l'étoffe l'aspect satiné d'un daim naturel. Il est prévu la possibilité d'utiliser des fils composites à microfilaments adhérents , mais dans ce cas l'étoffe subit divers traitements,préalables à l'action des jets de fluide, et destinés à individualiser les microfilaments , relaxation dans un bain d'eau chaude , séchage , grattage , fixation thermique.In document EP.A.10.546 the action of the water jets is intended to give the fabric the satin appearance of a natural suede. The possibility is provided of using composite threads with adherent microfilaments, but in this case the fabric undergoes various treatments, prior to the action of the jets of fluid, and intended to individualize the microfilaments, relaxation in a water bath hot, drying, scraping, thermal fixing.
Ainsi le mérite en revient au demandeur d'avoir fait la preuve que l'action de jets d'eau à une pression d'au moins 4.10⁶Pa était capable de désolidariser les microfilaments unitaires , en plus de la modification de la structure proprement dite, sans rupture des microfilaments: les microfilaments unitaires des filaments sont détachés soit les uns des autres s'il s'agit d'un filage lamellaire soit de la matrice s'il s'agit d'un filage en étoile.Thus the credit goes to the applicant for having demonstrated that the action of water jets at a pressure of at least 4.10⁶Pa was capable of dissociating the unitary microfilaments, in addition to the modification of the structure proper, without breaking of the microfilaments: the unitary microfilaments of the filaments are detached either from each other if it is a lamellar spinning or from the matrix if it is a star spinning.
Le procédé de l'invention permet d'obtenir un effet tout-à-fait reproductible , s'agissant de simples réglages des conditions physiques : vitesse de la grille, pression des jets d'eau, notamment.The method of the invention makes it possible to obtain a completely reproducible effect, in the case of simple adjustments of the physical conditions: speed of the grid, pressure of the water jets, in particular.
De préférence la grille support se déplace de manière continue sous plusieurs rampes comportant chacune un ensemble de buses d'injection de jets d'eau à haute pression, la pression de l'eau étant identique ou différente d'une rampe à l'autre. Avantageusement la pièce est soumise à l'action de jets à des pressions de plus en plus élevées.Preferably, the support grid moves continuously under several ramps, each comprising a set of high-pressure water jet injection nozzles, the water pressure being identical or different from one ramp to another. Advantageously, the part is subjected to the action of jets at increasingly higher pressures.
Par exemple la vitesse de défilement de la pièce étant comprise entre 20 et 100m/mn, celle-ci est soumise successivement à l'action de quatre rampes de jets d'eau à des pressions étagées respectivement de 4.10⁶ à 20.10⁶Pa.For example, the running speed of the part being between 20 and 100 m / min, it is successively subjected to the action of four ramps of water jets at stepped pressures respectively of 4.10⁶ to 20.10⁶Pa.
Certains fils constitutifs de la pièce sont par exemple des fils composés de filaments à microfilaments adhérents obtenus par filage en étoile, chaque filament ayant un titre de 2dtex environ et comportant de 6 à 8 microfilaments unitaires en polyester de 0,2 à 0,4dtex, assemblés grâce à une matrice en polyamide.Some constituent threads of the part are for example threads composed of filaments with adherent microfilaments obtained by star spinning, each filament having a titer of approximately 2dtex and comprising from 6 to 8 polyester microfilaments from 0.2 to 0.4dtex, assembled using a polyamide matrix.
D'autres avantages et caractéristiques de l'invention apparaîtront plus clairement dans la description qui va être faite de plusieurs traitements de pièces textiles par jets d'eau haute pression, illustrés par le dessin annexé dans lequel :

L'installation 1 de traitement qui va être décrite convient en particulier pour les pièces textiles , tissus ou tricots , enroulées sous forme de bobines 2 de bandes continues. Cette installation 1 comporte un ensemble de moyens réalisant le positionnement et le transport de la pièce 3, à savoir de l'amont vers l'aval un arbre 4, entraîné par un moteur non représenté, sur lequel est emmanchée la bobine 2 , des rouleaux 5 de tension, une grille support 6 consistant en un tapis sans fin enroulé et tendu entre deux cylindres 7,8 entraînés à la même vitesse linéaire que l'arbre 4, la pièce 3 reposant sur la partie supérieure 6a de la grille 6, et enfin un rouleau de détour 9 coopérant avec un arbre 10 d'enroulement de la bobine 11 constituée de la pièce 3 traitée.The
Par simplification on n'a représenté sur la figure 1 que deux rampes 12,13 d'injection d'eau à haute pression. Chaque rampe est alimentée par une pompe 14,15 capable de travailler à des pressions, réglables , allant de 4.10⁶Pa (40 bars) à plus de 20.10⁶ Pa (200 bars). Chaque rampe 12,13 comporte une plaque percée d'un ensemble d'orifices faisant office de buses d'injection 16 réparties d'une part sur toute la largeur utile de la grille 6 à raison d'un orifice tous les 2mm et d'autre part sur plusieurs rangées, par exemple trois rangées ont été représentées sur la figure 1. L'eau à haute pression sortant des buses d'injection 16 se présente sous forme de jets extrêmement fins, ayant un diamètre de l'ordre de 100 à 150 micromètres.For simplification, FIG. 1 shows only two
Des caissons d'aspiration 17,18 sont placés en vis-à-vis des rampes 12,13 d'injection sous la partie supérieure 6a de la grille 6 tandis que les rampes se trouvent au-dessus de cette partie supérieure 6a, les buses 16 étant dirigées perpendiculairement au plan de ladite partie supérieure 6a et donc à la pièce 3.
La grille support 6 est une grille métallique de 100mesh (c'est-à-dire de 100 mailles au pouce) réalisée avec des fils de 200micromètres de diamètre.The
Un tunnel de séchage 19 est placé sur le passage de la pièce 3 traitée après le cylindre 8 de sortie et avant le rouleau de détour 9.A
On a traité un tissu polyester d'environ 130g/m² ayant comme fil de chaîne un fil conventionnel faisant 90dtex, et comportant 136 filaments continus , et comme fil de trame un fil de filaments continus à microfilaments adhérents obtenu par filage en étoile. Un tel fil est représenté sur la figure 2A. Il comporte six microfilaments 20 unitaires en polyester ; chaque microfilaments 20 a en coupe transversale la forme d'un quartier d'orange; les six microfilaments 20 sont séparés par une matrice 21 en polyamide ayant six branches 22 radiales symétriquement réparties autour de l'axe longitudinal 23. Chaque microfilament unitaire 20 en polyester a un titrage compris entre 0,2 et 0,4dtex.A polyester fabric of about 130 g / m² has been treated having as warp yarn a conventional yarn making 90 dtex, and comprising 136 continuous filaments, and as weft yarn a continuous filament yarn with adherent microfilaments obtained by star spinning. Such a wire is shown in Figure 2A. It comprises six unitary polyester microfilaments; each
Le traitement du tissu ci-dessus a été réalisé à 20m/mn, par passage sous quatre rampes d'injection, l'eau étant respectivement à 6.10⁶Pa, 8.10⁶Pa, 20.10⁶Pa et 20.10⁶Pa.The treatment of the above fabric was carried out at 20m / min, by passing under four injection ramps, the water being respectively at 6.10⁶Pa, 8.10⁶Pa, 20.10⁶Pa and 20.10⁶Pa.
Après un tel traitement on observe que les microfilaments unitaires 20 ont été décollés de la matrice 21, sous l'impact des jets d'eau , comme cela est illustré sur la figure 2B. Mais on ne constate de dégradation ni des microfilaments 20 ni de la matrice 21; le tissu n'a donc pas perdu de poids.After such a treatment, it is observed that the
L'action combinée de l'individualisation des microfilaments unitaires 20 et du déplacement relatif desdits microfilaments 20 les uns par rapport aux autres dû aussi à l'action des jets d'eau donne au tissu une très grande souplesse et un clos très élevé. Le clos correspond à la répartition des filaments et des microfilaments par rapport au volume du tissu.The combined action of the individualization of the
Il existe d'autres types de fils à microfilaments adhérents, notamment ceux montrés aux figures 3 et 4. Sur la figure 3 on a représenté un fil sans âme, c'est-à-dire que la matrice de collage des quatre microfilaments 24 en polyester est constituée de quatre microfilaments 25 en polyamide accolés à deux microfilaments 24 successifs de polyester.There are other types of son with adherent microfilaments, in particular those shown in FIGS. 3 and 4. In FIG. 3, a coreless wire is shown, that is to say that the bonding matrix of the four
Sur la figure 4 on a représenté un fil du type lamellaire dans lequel les microfilaments 26 en polyester correspondent à des tranches longitudinales d'un filament de section sensiblement circulaire. L'auto-adhésion entre les quatre microfilaments 26 est obtenue du fait qu'au filage les quatre lamelles ne sont réunies qu'après un certain temps de refroidissement du polyester.FIG. 4 shows a thread of the lamellar type in which the
Les pièces textiles réalisées avec des fils à microfilaments adhérents tels que décrits ci-dessus ont été traitées sur l'installation 1. Il a été également constaté que les microfilaments 24,26 étaient individualisés sous l'impact des jets d'eau haute pression, sans dégradation.The textile pieces produced with adherent microfilament yarns as described above were treated on the
L'invention n'est pas limitée aux traitements qui ont été décrits à titre d'exemples non limitatifs mais en couvre toutes les variantes.The invention is not limited to the treatments which have been described by way of nonlimiting examples but covers all the variants.
On comprend que l'invention repose sur l'utilisation de jets d'eau à des pressions d'au moins 4.10⁶ Pa (40 bars) pour modifier la structure de pièces textiles, tissus ou tricots, dont les fils constitutifs sont déjà assemblés entre eux. Cette modification de structure consiste dans la séparation mécanique et le déplacement relatif de microfilaments qui avaient, dans le fil avant traitement et lors du tissage ou tricotage, une certaine adhérence.It is understood that the invention is based on the use of water jets at pressures of at least 4.10⁶ Pa (40 bars) to modify the structure of textile pieces, fabrics or knits, whose constituent yarns are already assembled between them. This structural modification consists in the mechanical separation and the relative displacement of microfilaments which had, in the thread before treatment and during weaving or knitting, a certain adhesion.
Partant de ce concept il revient à l'homme du métier de choisir les conditions de traitement en fonction de la pièce à traiter et de l'effet recherché. En particulier un traitement localisé ou un traitement à des pressions localement différenciées peut conduire à des effets spéciaux, sans sortir pour autant du cadre de la présente invention.Starting from this concept, it is up to the person skilled in the art to choose the treatment conditions according to the part to be treated and the desired effect. In particular localized treatment or treatment at locally differentiated pressures can lead to special effects, without thereby departing from the scope of the present invention.
