Abstract

The yarn (2), before passing into the texturing element (6), is subjected to the action of a fluid current through a nozzle (11) under such a pressure that no appreciable intertwining of filaments is produced. The method produces textured yarns than can easily be unwound without altering their properties.

Description

La présente invention concerne un procédé perfectionné permettant l'obtention de fils texturés, et plus particulièrement de fils texturés par fausse torsion ; elle concerne également une installation permettant la mise en oeuvre de ce procédé.The present invention relates to an improved method for obtaining textured yarns, and more particularly textured yarns by false twist; it also relates to an installation allowing the implementation of this process.

Dans la suite de la description, par mesure de sim- plificâtion, l'invention sera décrite plus particulièrement appliquée à la texturation de fils par fausse torsion, mais il est évident que cela n'est pas limitatif et, éventuellement, elle pourrait également être appliquée à d'autres techniques de texturation telles que celles faisant appel au bourrage, à des engrenages, à un passage sur une arête...In the following description, for the sake of simplification, the invention will be described more particularly applied to the texturing of threads by false twisting, but it is obvious that this is not limiting and, possibly, it could also be applied to other texturing techniques such as those using stuffing, gears, passing over an edge ...

La texturation est une opération bien classique en textile qui a pour but essentiel d'augmenter l'aspect gonflant et le volume apparent des fils, généralement à filaments continus, avec ou sans augmentation concomitante de l'élasticité.Texturing is a very classic textile operation which has the essential aim of increasing the swelling aspect and the apparent volume of the threads, generally with continuous filaments, with or without concomitant increase in elasticity.

Les techniques permettant de réaliser un tel traitement de texturation peuvent être classées en deux grandes familles. Dans la première, à laquelle appartient la texturation par fausse torsion, l'augmentation du gonflant et éventuellement de l'élasticité, est obtenue en provoquant une déformation mécanique des filaments élémentaires, déformation qui est fixée de manière permanente sous l'action d'un traitement thermique suivi d'un refroidissement.The techniques for carrying out such a texturing treatment can be classified into two main families. In the first, to which the false twist texturing belongs, the increase in bulking and possibly in elasticity is obtained by causing mechanical deformation of the elementary filaments, a deformation which is fixed permanently under the action of a heat treatment followed by cooling.

Dans la seconde, qui a fait l'objet des US-A-2 852 906 et 2 869 967,' l'augmentation de la volumino- sité est obtenue en faisant passer, en suralimentation, d'un fil à filament continu dans une buse formant une zone de turbulence qui provoque la séparation des filaments de manière à former une multitude de spires, boucles et autres circonvolutions, imbriquées les unes dans les autres, le fil ainsi traité étant réceptionné avec une tension aussi faible que possible.In the second, which has been the subject of US-A-2 852 906 and 2 869 967, the increase in voluminosity is obtained by passing, in supercharging, a continuous filament yarn through a nozzle forming a zone of turbulence which causes the separation of the filaments so as to form a multitude of turns, loops and other convolutions, nested one inside the other, the wire thus treated being received with as low a voltage as possible.

La présente invention vise plus particulièrement un perfectionnement apporté aux procédés et dispositifs de texturation de la première famille et, plus particu-- lièrement au procédé de texturation par fausse torsion.The present invention relates more particularly to an improvement made to the texturing methods and devices of the first family and, more particularly to the texturing process by false twist.

La technique de texturation par fausse torsion est actuellement parfaitement maitrisée par les techniciens. L'un des problèmes qui se pose actuellement dans ce domaine est celui du dévidage des enroulements formés, dévidage qui est effectué à des vitesses de plus en plus élevées compte-tenu des performances actuelles des métiers a tricoter ou à tisser. Eh effet, il a été constaté que l'augmentation du volume des bobines et des vitesses de défilage, vitesse qui, de nos jours, dépasse fréquemment 1000 m/mn, avait pour conséquence d'entraîner un nombre de casses relativement important. Pour pallier cet inconvénient, la solution susceptible d'être envisagée par les techniciens était de modifier les conditions de bobinage après texturation. Il pourrait également être envisagé de traiter le fil texturé avant ou lors du renvidage par exemple de le soumettre à un traitement par ébourriffement à l'aide d'un fluide sous-pression, tel que décrit dans la demande de Certificat d'Addition n° 777 03552 (publié sous le n° 2 379 626) au nom du Demandeur, compte tenu du fait que la technique décrite dans ce document avait permis de constater que le fil obtenu était plus facile à dévider (cf. p 2 ligne 2 de la demande publiée). Cependant, de telles solutions ne sont pas envisageables, soit du fait de leur complexité (modification des conditions de renvidage), soit du fait qu'elles modifient les propriétés textiles (gonflant, élasticité) des fils formés.The false twist texturing technique is currently perfectly mastered by technicians. One of the problems which currently arises in this field is that of the unwinding of the windings formed, reeling which is carried out at increasingly high speeds given the current performance of the knitting or weaving looms. Indeed, it has been observed that the increase in the volume of the reels and in the running speeds, a speed which, these days, frequently exceeds 1000 m / min, has the consequence of causing a relatively large number of breaks. To overcome this drawback, the solution likely to be envisaged by the technicians was to modify the winding conditions after texturing. It could also be envisaged to treat the textured yarn before or during winding, for example to subject it to a treatment by ruffling using a pressurized fluid, as described in the request for Certificate of Addition n ° 777 03552 (published under No. 2,379,626) in the name of the Applicant, taking into account the fact that the technique described in this document had made it possible to observe that the thread obtained was easier to unwind (cf. p 2 line 2 of the published request). However, such solutions cannot be envisaged, either because of their complexity (modification of the winding conditions), or because they modify the textile properties (swelling, elasticity) of the threads formed.

Il aurait également été possible d'envisager de soumettre les fils texturés, immédiatement avant renvidage, à un traitement d'entrelaçage, par exemple réalisé conformément aux enseignements'du FR.A. 1 235 718. En effet, un tel traitement, utilisé couramment de nos jours afin de remplacer la torsion, permet de donner de la cohésion à des fils sans cependant qu'il se produise des boucles ou circonvolutions. Si cette solution permet de faciliter le dévidage des enroulements formés, elle implique cependant de travailler avec des pressions en fluide relativement importantes en général supérieures à 1 bar, ce qui augmente notablement les coûts de production. De plus, les propriétés de gonflant et/ou d'élasticité des fils texturés formés s'en trouvent modifiées.It would also have been possible to consider subjecting the textured threads, immediately before winding, to an interlacing treatment, for example carried out in accordance with the teachings of the FR.A. 1,235,718. Indeed, such treatment, commonly used today in order to replace the twist, allows to give cohesion to wires without however producing curls or convolutions. If this solution facilitates the unwinding of the windings formed, it however involves working with relatively high fluid pressures generally greater than 1 bar, which significantly increases production costs. In addition, the properties of swelling and / or elasticity of the textured yarns formed are thereby modified.

Or, on a trouvé et c'est ce qui fait l'objet de la présenta invention, un procédé simple et économique qui permet d'obtenir des enroulements de fils texturés dévidables à grande vitesse, Dans variation de tension ni production de casses, tout en conservant auxdits fils leurs propriétés de gonflant et/ou d'élasticité d'origine.Now, we have found and this is what is the subject of the present invention, a simple and economical process which makes it possible to obtain windings of textured wires which can be unwound at high speed. In voltage variation or breakage production, everything retaining their original swelling and / or elasticity properties in said yarns.

D'une manière générale, le procédé selon l'invention permettant la texturation d'un fil, notamment par fausse torsion, et plus particulièrement d'un fil partiellement ou non étiré, l'étirage étant réalisé lors de l'opération de texturation, se caractérise par le fait que ledit fil est soumis, avant passage dans les organes de texturation, à un courant de fluide dans des conditions de pression telles qu'il ne se produit pas d'entrelacement substantiel des filaments, ni à plus forte raison, de boucles ou de circonvolutions externes provoquant une modification du gonflant du fil élémentaire qui doit être texturé ultérieurement.In general, the method according to the invention allowing the texturing of a yarn, in particular by false twisting, and more particularly of a partially or unstretched yarn, the stretching being carried out during the texturing operation, is characterized by the fact that said thread is subjected, before passage through the texturing members, to a stream of fluid under pressure conditions such that there is no substantial intertwining of the filaments, let alone loops or external convolutions causing a modification of the bulking of the elementary yarn which must be textured later.

Un tel traitement par fluide est réalisé de manière connue au moyen d'une buse d'entrelaçage, ladite buse étant alimentée par un fluide sous faible pression, pression en général de l'ordre de 0,5 bar.Such a fluid treatment is carried out in a known manner by means of an interlacing nozzle, said nozzle being supplied with a fluid under low pressure, pressure generally of the order of 0.5 bar.

L 'invention et les avantages qu'elle apporte seront cependant mieux compris grâce à l'exemple de réalisation donné ci-après à titre indicatif mais non limitatif et qui est illustré par les schémas annexés dans lesquels :

  • - la figure 1 illustre vu de côté, une machine d'étirage texturation par fausse torsion conventionnelle, du type décrit dans le FR-A-2 347 466 au nom du demandeur, ladite machine étant équipée d'une buse de soufflage conformément à l'invention ;
  • - les figures 2 et 3 sont respectivement des vues en perspective et en coupe selon l'axe A d'une buse utilisable pour .la mise en oeuvre du procédé selon l'invention.
The invention and the advantages which it provides will however be better understood thanks to the embodiment given below by way of indication but not limitation and which is illustrated by the attached diagrams in which:
  • - Figure 1 illustrates seen from the side, a machine conventional texturing by false twist, of the type described in FR-A-2 347 466 in the name of the applicant, said machine being equipped with a blowing nozzle according to the invention;
  • - Figures 2 and 3 are respectively perspective and sectional views along the axis A of a nozzle usable for .the implementation of the method according to the invention.

Si l'on se reporte à la figure 1 annexée, la machine de texturation par fausse torsion équipée conformément à l'invention se compose, de manière connue, d'une pluralité de positions de traitement formée chacune essentiellement dans l'ordre :

  • - d'une source (1) de fil (2), telle qu'une cantre ou un ratelier,
  • - un dispositif délivreur de fil (3) à lanières par exemple,
  • - d'un organe de chauffage (4) et d'une zone de refroidissement (5),
  • - d'une broche de texturation par fausse torsion (6),
  • - un deuxième délivreur (7) analogue ou différent du délivreur (3),
  • - un deuxième four (8),
  • - un troisième délivreur (9),
  • - un organe de réception (10) du fil sous forme de bobine.
If reference is made to the appended FIG. 1, the false-twist texturing machine equipped in accordance with the invention consists, in known manner, of a plurality of processing positions each formed essentially in the order:
  • - a source (1) of wire (2), such as a creel or a rack,
  • a wire delivery device (3) with straps for example,
  • - a heating element (4) and a cooling zone (5),
  • - a false twist texturing spindle (6),
  • - a second deliverer (7) similar or different from the deliverer (3),
  • - a second oven (8),
  • - a third deliverer (9),
  • - A receiving member (10) of the wire in the form of a coil.

Bien entendu, l'invention peut également être appliquée dans le cas de machines de texturation ne comportant pas de second four (8), le fil étant alors directement amené du second délivreur (7) pour être renvidé en (10).Of course, the invention can also be applied in the case of texturing machines not comprising a second oven (8), the thread then being brought directly from the second deliverer (7) to be returned to (10).

Une telle machine permet de traiter des fils (2) partiellement étirés, l'étirage étant réalisé simultanément à l'opération de fausse torsion entre les délivreurs (3) et (7).Such a machine makes it possible to treat partially drawn wires (2), the drawing being carried out simultaneously with the false twist operation between the deliverers (3) and (7).

Afin de permettre un dévidage aisé lors de l'utilisation des bobines de fil produit, une telle installation comporte, conformément à l'invention, entre le premier délivreur (3) et la cantre d'alimentation supportant les bobines (1), une buse (11) reliée à une source d'alimentation en air comprimé (non représenté).In order to allow easy reeling during the use of coils of produced wire, such an installation comprises, in accordance with the invention, between the first deliverer (3) and the feeder block supporting the coils (1), a nozzle (11) connected to a source of compressed air supply (not shown).

Une telle buse peut être réalisée de manière simple comme illustré aux figures 2 et 3, et se compose essentiellement d'un corps (12) comportant un canal longitudinal (13) dans lequel débouche la source d'alimentation en fluide (14). De préférence, le canal (13) est ouvert de manière à avoir une fente (15) permettant un passage aisé du fil. Les éléments de guidage (17-18) sont prévus de part et d'autre de la buse (11) dans le prolongement du canal (13). Une buse de conception parfaitement simple peut être utilisée dans le cas du procédé selon l'invention, compte-tenu du fait que la pression en fluide nécessaire pour la mise en oeuvre de ce procédé est très faible, en général voisine de 0,5 bar, et que sa fonction n'est pas de produire un entrelacement des filaments. Bien entendu, des buses plus complexes utilisées pour l'entrelacement des fils pourraient être employées, la pression en air de ces buses étant cependant réglée à une valeur très basse, valeur à laquelle normalement, aucun entrelacement ou ébourriffement n'est produit sur les fils.Such a nozzle can be produced in a simple manner as illustrated in FIGS. 2 and 3, and essentially consists of a body (12) comprising a longitudinal channel (13) into which the fluid supply source (14) opens. Preferably, the channel (13) is open so as to have a slot (15) allowing easy passage of the wire. The guide elements (17-18) are provided on either side of the nozzle (11) in the extension of the channel (13). A nozzle of perfectly simple design can be used in the case of the process according to the invention, taking into account the fact that the fluid pressure necessary for the implementation of this process is very low, in general close to 0.5 bar , and that its function is not to produce an interlacing of the filaments. Of course, more complex nozzles used for interlacing the wires could be used, the air pressure of these nozzles being however set at a very low value, a value at which normally, no interlacing or tangling is produced on the wires .

De manière surprenante, il a été constaté qu'en traitant des fils partiellement étirés dans de telles conditions, le traitement de texturation proprement dit s'effectuait dans des conditions normales, les fils produits présentant un gonflant et une élasticité similaire aux fils produits antérieurement mais, qu'en revanche, lors de l'utilisation de ces fils, les enroulements formés étaient beaucoup plus faciles à dévider, les casses étant pratiquement éliminées. A titre indicatif, pour un fil de polyester 70 dtex/34 brins traité conformément à l'invention avec une buse (11) alimentée sous une pression de 0,5 bar, lors d'un dévidage à plus de 1000 m/mn, il ne se produisait aucune casse alors que sans traitement conforme à l'invention pour un même enroulement, il se produisait six casses pour une bobine. Tous ces comparatifs ont été réalisés en réalisant une bobine ayant un diamètre de 250 mm, pesant 5,2 kg et ayant une densité de 0,53 kg/dm3.Surprisingly, it has been found that by treating partially drawn yarns under such conditions, the texturing treatment proper is carried out under normal conditions, the yarns produced having a swelling and an elasticity similar to the yarns produced previously but , that on the other hand, when using these wires, the windings formed were much easier to unwind, the breakages being practically eliminated. As an indication, for a 70 dtex / 34-strand polyester yarn treated in accordance with the invention with a nozzle (11) supplied at a pressure of 0.5 bar, when it is unwound at more than 1000 m / min, it no breakage occurred while without treatment according to the invention for the same winding, there were six breaks for a coil. All of these comparisons were made by making a coil having a diameter of 250 mm, weighing 5.2 kg and having a density of 0.53 kg / dm 3 .

Un tel exemple montre bien les avantages apportés par l'invention.Such an example clearly shows the advantages provided by the invention.

Bien entendu, cet exemple n'est pas limitatif et une invention pourrait être appliquée à d'autres techniques de texturation utilisant comme matières de départ des fils non ou partiellement étirés.Of course, this example is not limiting and an invention could be applied to other texturing techniques using as starting materials un or partially drawn threads.
