Description

La présente invention concerne un fil gainé d'aspect naturel. La présente invention concerne encore un textile réalisé à partir d'un fil gainé d'aspect naturel. La présente invention se rapporte également un procédé de fabrication d'un fil gainé d'aspect naturel.The present invention relates to a natural-looking sheathed wire. The present invention further relates to a textile made from a natural-looking sheathed yarn. The present invention also relates to a method of manufacturing a natural-looking sheathed wire.

Malgré une demande commerciale de plus en plus recherchée, on ne sait pas encore fabriquer des fils à base de matériaux thermoplastiques, qui allient à la fois d'excellentes performances mécaniques et un aspect naturel décelable à la vue et au toucher. En outre, les exigences d'ordre environnementales sont rarement satisfaites en ce qui concerne l'emploi de matériaux d'origine naturelle et l'aptitude à être recyclé pour obtenir des produits à base de fils destinés à toutes utilisations, par exemple des textiles. C'est particulièrement le cas pour des textiles présentant des applications extérieures, soumis aux intempéries et au soleil, et pour les textiles devant résister au feu.Despite an increasingly sought-after commercial demand, it is not yet possible to manufacture thermoplastic-based yarns, which combine excellent mechanical performance with a natural appearance that is detectable by sight and touch. In addition, environmental requirements are rarely met with regard to the use of naturally occurring materials and the ability to be recycled to produce yarn-based products for all uses, for example textiles. This is particularly the case for textiles with exterior applications, weather and sun, and for textiles that must withstand fire.

État de la techniqueState of the art

On connaît d'après le document FR- 2.781.492 un matériau thermoplastique comprenant des fibres d'origine végétale, destinées à améliorer l'aspect de perception par le consommateur.Document FR-2 781 462 discloses a thermoplastic material comprising fibers of vegetable origin, intended to improve the appearance of perception by the consumer.

Cependant, l'aspect extérieur des produits obtenus s'avère relativement décevant et très peu compatible avec ce qui est actuellement recherché par le consommateur.However, the external appearance of the products obtained is relatively disappointing and very little compatible with what is currently sought by the consumer.

On connaît également d'après le document FR- 2.617.205 un fil gainé et un procédé de fabrication d'un fil par gainage d'une âme avec une composition ignifuge, pour obtenir un fil et ensuite un tissu avec des propriétés ignifuges.It is also known from FR-2.617.205 a sheathed wire and a method of manufacturing a wire by sheathing a core with a flame retardant composition, to obtain a wire and then a fabric with flame retardant properties.

Cependant, le fil obtenu garde un toucher lisse, peu favorable à une gamme de produits classés comme étant « écologique » et ne pouvant s'inscrire que difficilement dans des considérations d'ordre écologique.However, the wire obtained has a smooth feel, unfavorable to a range of products classified as being "ecological" and can hardly be included in ecological considerations.

On connaît d'après le document WO 99/42644 un fil composite élastomère gainé avec des fibres discontinues ajoutées dans une étape supplémentaire.It is known from WO 99/42644 an elastomeric composite yarn sheathed with staple fibers added in a further step.

Autrement dit, avec une quantité de fibres inférieure ou égale à 20 % présentes dans la gaine, le fil va présenter un aspect de surface extérieur particulièrement intéressant. Dans une première variante de réalisation, et afin d'accroître la résistance, le fil d'âme peut être un fil multifilaments. Le fil d'âme peut être un fil de polyester, d'alcool polyvinylique ou de polyamide.

The invention will be well understood and its various advantages and different characteristics will become more apparent in the following description, nonlimiting examples of embodiment, with reference to the appended schematic drawing, in which:
  • Figure 1 shows an enlarged longitudinal view of a sheathed wire according to the state of the art and a sheathed wire according to the invention;

Description détailléedetailed description

L'âme est recouverte par extrusion ou enduction d'une couche de matériau polymère périphérique. Les photographies agrandies environ 20 fois de la Figure 1 montrent une comparaison entre un fil gainé (1) selon l'état de la technique (placé à gauche), représenté par le document FR- 2.617.205 et un fil gainé (2) selon la présente invention (placé à droite). Du fait de la présence de fibres discontinues, la surface extérieure du fil (2) obtenu par le procédé selon l'invention présente un aspect irrégulier et ressemble à de la ficelle. Le diamètre moyen peut ainsi être inférieur à 1 mm et varier entre 0,6 mm et 0,9 mm. En revanche, la surface extérieure du fil gainé traditionnel (1) est lisse.The core is covered by extrusion or coating with a layer of peripheral polymeric material. The photographs enlarged approximately 20 times of Figure 1 show a comparison between a wire sheath (1) according to the state of the art (placed on the left), represented by the document FR-2.617.205 and a sheathed wire (2) according to the current invention (placed on the right). Due to the presence of staple fibers, the outer surface of the yarn (2) obtained by the method according to the invention has an irregular appearance and looks like string. The average diameter can thus be less than 1 mm and vary between 0.6 mm and 0.9 mm. In contrast, the outer surface of the traditional sheathed wire (1) is smooth.

Avantageusement, et en pratique, le fil d'âme est un fil à multifilaments, haute ténacité c'est-à-dire présentant une ténacité de l'ordre d'au moins 50 cN/tex. Les multiples filaments de l'âme sont tordus ou non, entrelacés ou non, assemblés ou non, texturés ou non, en fonction du fil gainé final souhaité.Advantageously, and in practice, the core wire is a multifilament yarn, high tenacity that is to say having a toughness of the order of at least 50 cN / tex. The multiple filaments of the soul are twisted or not, interlaced or not, assembled or not, textured or not, depending on the final sheathed wire desired.

La Figure 2 montre une coupe transversale du fil gainé (2) prise au microscope optique avec un agrandissement d'environ 150 fois. Dans cette réalisation du fil gainé (2), les multiples filaments (3) en polyester de l'âme (4) apparaissent au centre. La gaine (6) à base de compound PVC entoure l'âme (4). Comme le montre cette photographie, la gaine (6) intègre les fibres de chanvre (7) noyées dans le PVC. Le pourtour de la gaine (6) est très irrégulier, conférant à l'ensemble du fil un toucher naturel.Figure 2 shows a cross-section of the sheathed wire (2) taken under an optical microscope with an enlargement of about 150 times. In this embodiment of the sheathed wire (2), the multiple polyester filaments (3) of the core (4) appear in the center. The sheath (6) based on PVC compound surrounds the core (4). As shown in this photograph, the sheath (6) incorporates the hemp fibers (7) embedded in the PVC. The perimeter of the sheath (6) is very irregular, giving the whole thread a natural touch.

Dans une autre variante, on réalise directement par co-extrusion l'âme et la gaine.In another variant, the core and the sheath are produced directly by coextrusion.

Avantageusement, et en pratique, la gaine (6) est extrudée autour du fil d'âme (4). Les compositions de polymère thermoplastique de la gaine comprennent en outre avantageusement des adjuvants complémentaires : au moins un agent anti-U.V., et/ou au moins un agent biocide, et/ou au moins une charge minérale, et/ou au moins un pigment, et/ou au moins un agent d'ignifugation. L'agent d'ignifugation peut être des charges ignifugeantes minérales, tels que par exemple des oxydes d'antimoine, du trihydrate d'alumine, de l'oxyde de zinc ou de magnésium.Advantageously, and in practice, the sheath (6) is extruded around the core wire (4). The thermoplastic polymer compositions of the cladding furthermore advantageously comprise complementary adjuvants: at least one anti-UV agent, and / or at least one biocidal agent, and / or at least one mineral filler, and / or at least one pigment, and / or at least one flame retardant. The flame retardant may be inorganic flame retardants, such as, for example, antimony oxides, alumina trihydrate, zinc oxide or magnesium oxide.

Le rapport en poids entre le fil d'âme (4) et la gaine (6) dépend à la fois des applications finales envisagées et du matériel d'extrusion ou d'enduction dont on dispose.The ratio by weight between the core wire (4) and the sheath (6) depends both on the final applications envisaged and the extrusion or coating equipment available.

De tels fils peuvent être employés dans de multiples applications, et notamment la fabrication de mobilier, typiquement des sièges de camping, habillages automobiles, revêtement de sols et murs, protections solaires, articles de bagagerie, toiles de protection et d'autres encore.Such yarns can be used in a variety of applications, including the manufacture of furniture, typically camping seats, car wraps, floor and wall coverings, sunscreens, luggage, protective cloths and more.

La Figure 3 montre un exemple de textile agrandi environ 10 fois, entièrement réalisé à partir de fils (2), avec une âme 100 % polyester gainée avec un compound PVC et fibres de chanvre selon l'invention, et thermofixés. Le textile comprend un fil de chaîne (8) à l'horizontale et deux fils de trame à la verticale (9 et 11). On notera que les fils présentent différentes colorations.Figure 3 shows an example of textile enlarged about 10 times, made entirely of yarn (2), with a 100% polyester core sheathed with a PVC compound and hemp fibers according to the invention, and heat set. The textile includes a thread chain (8) horizontally and two vertical weft threads (9 and 11). It will be noted that the threads have different colorations.

Exemples de réalisationExamples of realization

On réalise un fil gainé (2) selon la présente invention de la manière suivante. On gaine par extrusion par passage dans une filière un fil de polyester de 1100 dtex, commercialisé par la société Rhodia sous la dénomination « Type 156 ». La vitesse de défilement du fil est de 300 m/min.A sheathed wire (2) is made according to the present invention as follows. An 1100 dtex polyester yarn, marketed by Rhodia under the name "Type 156", is extruded by passing through a die. The running speed of the thread is 300 m / min.

La composition de gainage extrudé comprend :

  • 7 % de fibres de chanvre ; et
  • 93 % de PVC plastifié, formulé et pigmenté.
The extruded sheathing composition comprises:
  • 7% hemp fiber; and
  • 93% PVC plasticized, formulated and pigmented.

On obtient ainsi un fil gainé de 4700 dtex ayant un diamètre moyen de 0,67 mm ; en d'autres termes, en poids, le fil d'âme polyester représente 23,4 % et la gaine fibrée représente 76,6 %.A sheathed yarn of 4700 dtex having an average diameter of 0.67 mm is thus obtained; in other words, by weight, the polyester core yarn is 23.4% and the fibered sheath is 76.6%.

De plus, le fil gainé obtenu présente les caractéristiques et les propriétés mécaniques qui suivent :

  • résistance à la traction, 9,6 daN, et
  • allongement à la rupture, 14,5 %.
In addition, the sheathed wire obtained has the following characteristics and mechanical properties:
  • tensile strength, 9.6 daN, and
  • elongation at break, 14.5%.

Ce fil convient donc parfaitement pour la fabrication de textiles pouvant être thermofixés.This yarn is therefore perfectly suitable for the manufacture of textiles that can be heat set.

La présente invention n'est pas limitée aux modes de réalisation décrits et illustrés. De nombreuses modifications peuvent être réalisées, sans pour autant sortir du cadre défini par la portée du jeu de revendications.The present invention is not limited to the embodiments described and illustrated. Many modifications can be made, without departing from the scope defined by the scope of the set of claims.

Par exemple, on pourra concevoir une âme en différents matériaux, tels que des fibres de verre, des fibres optiques, un ou plusieurs fils métalliques.For example, one may design a core of different materials, such as glass fibers, optical fibers, or one or more metal wires.
