Abstract
Description
La présente invention concerne un procédé de fabrication de cordes destinées à être soumises à des tractions, notamment de cordes pour raquettes et instruments de musique, comprenant une étape dans laquelle on réalise un fil à partir de fibres, une étape dans laquelle on imprègne le fil avec une résine, une étape dans laquelle on enduit le fil imprégné avec une matière synthétique pour le munir d'une gaine, une étape dans laquelle on fait réticuler complètement la matière synthétique, et une étape dans laquelle on ajuste l'épaisseur de la gaine, ce procédé étant connu d'après le document FR-A-2 356 762.The present invention relates to a method of manufacturing strings intended to be subjected to traction, in particular strings for rackets and musical instruments, comprising a step in which a thread is made from fibers, a step in which the thread is impregnated with a resin, a step in which the impregnated wire is coated with a synthetic material to provide it with a sheath, a step in which the synthetic material is completely cross-linked, and a step in which the thickness of the sheath is adjusted , this process being known from document FR-A-2 356 762.
Les cordes obtenues par la mise en oeuvre du procédé ci-dessus comportent un fil central constitué de fibres continues. Lorsqu'elles sont montées sur des raquettes, ces cordes ont alors tendance à vibrer sous les impacts des balles et à transmettre leurs vibrations jusqu'au bras des joueurs. Or ces vibrations risquent d'engendrer des lésions anatomiques dites "tennis elbow" ayant des conséquences dommageables tant sur le jeu que sur la santé du joueur.The strings obtained by the implementation of the above method comprise a central wire made up of continuous fibers. When mounted on rackets, these strings then tend to vibrate under the impacts of the balls and transmit their vibrations to the players' arms. However, these vibrations risk generating anatomical lesions called "tennis elbow" having damaging consequences both on the game and on the player's health.
FR-A-2 356 762 décrit un procédé de fabrication de cordes, consistant à former au moins un faisceau de multifilaments continus, à imprégner le faisceau avec un adhésif thermodurcissable, à prépolymériser le produit d'imprégnation, à retordre le faisceau en évitant l'essorage des multifilaments imprégnés et à achever la polymérisation du produit d'imprégnation.FR-A-2 356 762 describes a method of manufacturing cords, consisting of forming at least one bundle of continuous multifilaments, impregnating the bundle with a thermosetting adhesive, prepolymerizing the impregnation product, twisting the bundle avoiding squeezing the impregnated multifilaments and completing the polymerization of the impregnation product.
Lorsqu'elles sont montées sur des raquettes de tennis, les cordes réalisées suivant ce procédé n'assurent toutefois qu'un certain amortissement des vibrations.When they are mounted on tennis rackets, the strings produced according to this process, however, only provide a certain damping of the vibrations.
La présente invention se propose plus particulièrement de remédier aux inconvénients des cordes actuelles qui sont destinées à être soumises à des tractions, et pour ce faire elle a pour objet un procédé du type comportant les étapes mentionnées ci-dessus, qui est caractérisé en ce que pour réaliser le fil, on utilise des fibres discontinues que l'on soumet à des opérations textiles d'intersecting et d'étirage-tordage, l'intersecting ayant pour but d'orienter les fibres parallèlement les unes aux autres, tandis que l'étirage-tordage permet d'obtenir un fil continu.The present invention more particularly proposes to remedy the drawbacks of current ropes which are intended to be subjected to pull-ups, and to do this it relates to a method of the type comprising the steps mentioned above, which is characterized in that to make the thread, we use staple fibers which are subjected to textile operations of intersecting and stretching-twisting, the intersecting having the aim of orienting the fibers parallel to each other, while the stretching-twisting makes it possible to obtain a continuous thread .
Les fibres discontinues permettent d'obtenir une corde capable de limiter et d'amortir plus rapidement les vibrations s'exerçant sur elle lorsqu'elle est soumise à des tractions. En montant cette corde sur une raquette, on peut donc éviter que les vibrations dues aux impacts des balles soient transmises au bras du joueur et affectent les performances de ce dernier.Staple fibers make it possible to obtain a rope capable of limiting and damping the vibrations exerted on it more quickly when it is subjected to traction. By mounting this rope on a racket, we can avoid that the vibrations due to the impacts of the balls are transmitted to the player's arm and affect the performance of the latter.
Pour obtenir une corde présentant un excellent pouvoir d'amortissement, il est souhaitable que les fibres discontinues aient une longueur de l'ordre de 20 à 500 mm, de préférence de 50 à 250 mm, titrent de l'ordre de 1 à 100 dtex, de préférence de l'ordre 1 à 20 dtex et présentent une frisure de l'ordre de 4 à 12 par centimètre.To obtain a rope with excellent damping power, it is desirable that the staple fibers have a length of the order of 20 to 500 mm, preferably 50 to 250 mm, size of the order of 1 to 100 dtex , preferably of the order of 1 to 20 dtex and have a crimp of the order of 4 to 12 per centimeter.
Il est par ailleurs avantageux d'utiliser des fibres discontinues réalisées en au moins un matériau choisi dans le groupe comprenant les fibres textiles naturelles, le carbone, le verre, les métalloïdes, les métaux, les alliages métalliques, les polyesters, les polyéthers, les polyuréthanes, les polyamides, les polyoléfines, les composés acryliques, les composés vinyliques et les aramides.It is also advantageous to use staple fibers made of at least one material chosen from the group comprising natural textile fibers, carbon, glass, metalloids, metals, metal alloys, polyesters, polyethers, polyurethanes, polyamides, polyolefins, acrylic compounds, vinyl compounds and aramides.
On précisera ici que les fibres discontinues peuvent être pleines ou creuses et avoir une section quelconque, leur section pouvant par exemple être ronde, elliptique, triangulaire, carrée, rectangulaire ou à plusieurs lobes.It will be specified here that the staple fibers can be solid or hollow and have any cross-section, their cross-section possibly for example being round, elliptical, triangular, square, rectangular or with several lobes.
Lors de la mise en oeuvre du procédé selon l'invention, il convient de réaliser les étapes d'intersecting et d'étirage-tordage avant l'étape d'imprégnation qui peut être réalisée en immergeant le fil dans un bac contenant la résine à l'état liquide.During the implementation of the method according to the invention, the steps of intersecting and stretch-twisting should be carried out before the impregnation step which can be carried out by immersing the wire in a tank containing the resin to be liquid state.
Il est par ailleurs souhaitable de faire réticuler complètement la résine d'imprégnation avant d'enduire le fil, la réticulation étant réalisée alors que le fil est mis en tension.It is also desirable to completely crosslink the impregnation resin before coating the wire, the crosslinking being carried out while the wire is under tension.
La réticulation réalisée sous tension permet d'obtenir une bonne liaison entre la résine et les fibres et par suite une corde présentant une meilleure résistance à la traction.The crosslinking carried out under tension makes it possible to obtain a good bond between the resin and the fibers and consequently a cord having a better tensile strength.
Conformément à l'invention, la résine d'imprégnation et la matière synthétique constituant la gaine peuvent être de même nature et consister en un matériau choisi dans le groupe comprenant les polyesters, les polyéthers, les polyamides, les époxydes, les polyuréthanes, les cyanoacrylates, les composés acryliques, les composés vinyliques et les composés phénoliques, ces différents matériaux pouvant être associés à des solvants et éventuellement à des colorants.According to the invention, the impregnation resin and the synthetic material constituting the sheath may be of the same nature and consist of a material chosen from the group comprising polyesters, polyethers, polyamides, epoxides, polyurethanes, cyanoacrylates , acrylic compounds, vinyl compounds and phenolic compounds, these various materials can be combined with solvents and optionally with dyes.
Selon une autre caractéristique du procédé conforme à l'invention, on peut avantageusement polir le fil imprégné avant de l'enduire avec la matière synthétique, ce polissage pouvant par exemple être réalisé en faisant passer le fil entre des disques abrasifs souples.According to another characteristic of the process in accordance with the invention, it is advantageous to polish the impregnated wire before coating it with the synthetic material, this polishing can for example be carried out by passing the wire between flexible abrasive discs.
Selon encore une autre caractéristique du procédé conforme à l'invention, on peut faire réticuler la résine d'imprégnation en chauffant le fil dans un four dont la température est réglée pour éviter une détérioration des fibres discontinues.According to yet another characteristic of the process according to the invention, the impregnation resin can be crosslinked by heating the wire in an oven whose temperature is adjusted to prevent deterioration of the staple fibers.
A titre d'exemple, on précisera que l'on fait circuler le fil imprégné dans le four de façon à ce qu'il séjourne dans ce dernier pendant une durée de l'ordre de 10 secondes à 10 minutes, de préférence de 30 secondes à 3 minutes.By way of example, it will be specified that the impregnated wire is circulated in the oven so that it remains in the latter for a period of the order of 10 seconds to 10 minutes, preferably 30 seconds. 3 minutes.
Pour obtenir une corde de diamètre constant, on peut avantageusement ajuster l'épaisseur de la gaine en faisant passer le fil enduit dans une série de filières de diamètres décroissants. A l'issue de cette opération de calibrage, l'épaisseur de la gaine peut être de l'ordre de 0,05 à 0,5 mm.To obtain a cord of constant diameter, it is advantageous to adjust the thickness of the sheath by passing the coated wire through a series of dies of decreasing diameters. At the end of this calibration operation, the thickness of the sheath can be of the order of 0.05 to 0.5 mm.
Les cordes obtenues par la mise en oeuvre du procédé décrit ci-dessus sont destinées à être utilisées dans des applications dans lesquelles elles sont susceptibles de subir des tractions, comme par exemple sur des raquettes ou des instruments de musique.The strings obtained by the implementation of the method described above are intended to be used in applications in which they are likely to undergo pulling, such as for example on rackets or musical instruments.
