Description

La présente invention concerne un tissu, plus particulièrement destiné à la réalisation de toits ouvrants ou de capotes, par exemple pour des bateaux.The present invention relates to a fabric, more particularly intended for realization of sunroofs or hoods, for example for boats.

Des tissus sont utilisés depuis de nombreuses années pour recouvrir les bateaux de toutes dimensions, qu'ils soient à moteur ou à voile. Les tissus sont soit fixés au-dessus de structures ou armatures métalliques de façon à former un toit, soit positionnés en recouvrant partiellement ou en fermant totalement un volume intérieur défini. Ces surfaces en tissus sont utilisées pour protéger les utilisateurs des intempéries et du soleil, tout en gardant une bonne translucidité naturelle nécessaire au pilotage ou tout simplement pour le confort visuel.Tissues have been used for many years to cover all sizes, whether motor or sail. The fabrics are either fixed above structures or metal frames so as to form a roof, are positioned in partially overlapping or completely closing a defined interior volume. These Fabric surfaces are used to protect users from the weather and the sun, while keeping a good natural translucency necessary for piloting or any simply for visual comfort.

Il existe plusieurs types de toits ouvrants et des capotes de bateaux. Pour les bateaux disposant de toitures rigides, des ouvertures sont aménagées avec un système de rails latéraux et de traverses coulissantes soutenant un textile, qui permet d'ouvrir et de fermer à volonté ces ouvertures. Ces systèmes sont appelés toits ouvrants. Pour les bateaux disposant de toitures rigides, le pont arrière est équipé d'auvents textiles repliables, pour assurer la fermeture étanche de l'habitacle en cas d'intempéries. Enfin, les bateaux ne disposant pas de toitures rigides sont équipés de capotes textiles soutenues par des systèmes d'arceaux repliables appelées aussi tauds ou plus communément biminis. Il existe une grande variété de formes et de dimensions de biminis adaptés à la taille et à la configuration des bateaux considérés.There are several types of sunroofs and boat tops. For the boats with rigid roofs, openings are fitted out with side rails and sliding rails supporting a textile, which allows opening and to close these openings at will. These systems are called sunroofs. For the boats with rigid roofs, the aft deck is equipped with textile awnings foldable, to ensure the tight closure of the cabin in case of bad weather. Finally, boats without rigid roofs are equipped with textile hoods supported by folding arch systems also known as awnings or more commonly biminis. There is a wide variety of shapes and sizes of biminis adapted to the size and configuration of the boats considered.

Dans chacun de ces cas, il est recherché une très grande souplesse et légèreté du tissu, afin d'assurer d'une part les pliages et dépliages successifs et d'autre part pour conserver une excellente translucidité.In each of these cases, it is sought a very great flexibility and lightness of the fabric, in order to ensure on the one hand the successive folds and unfoldings and on the other hand to maintain excellent translucency.

Etat de la techniqueState of the art

Il existe aujourd'hui trois grandes familles de tissus utilisés pour les capotes de bateaux : les tissus réalisés à partir de fils acryliques, les tissus avec armure textile polyester et enduction de PVC et enfin les textiles laminés. La souplesse et légèreté avantageuse obtenus avec les tissus connus pose par ailleurs un certain nombre d'inconvénients non encore résolus à l'heure actuelle. There are now three major families of fabrics used for boats: fabrics made from acrylic yarns, fabrics with textile armor polyester and PVC coating and finally laminated textiles. The flexibility and lightness advantageously obtained with the known fabrics poses a number of disadvantages not yet solved.

Une première série d'inconvénients est qu'il se forme des plis longitudinaux situés au droit des points de tension sur les grandes surfaces de capotes. Outre des zones d'affaiblissement et d'usure locale du tissu, ces plis créent des gondolements et des creux formant des poches. Ces poches recueillent de l'eau de pluie, de la poussière, des feuilles mortes et des saletés diverses. Les capotes en deviennent inesthétiques et ces accumulations non souhaitées sur les capotes repliables provoquent des retombées désagréables sur l'utilisateur lorsqu'il procède à leur rangement.A first set of disadvantages is that longitudinal folds are formed located at the points of tension on large surfaces of hoods. In addition to areas weakening and local wear of the fabric, these folds create buckles and hollow forming pockets. These pockets collect rainwater, dust, dead leaves and various dirt. The hoods become unsightly and these Unwanted accumulations on folding hoods cause fallout unpleasant on the user when he arranges them.

Une deuxième série d'inconvénients est la perte d'étanchéité du toit. Lorsque les toits ouvrants sont fermés, des chenaux périphériques sont prévus pour faire écouler l'eau par ruissellement jusqu'à l'extérieur du bateau. La liaison entre la toile et le chenau est réalisée par la simple superposition de cette toile sur ce chenau, le maintien de l'un sur l'autre étant favorisé par la tension des arceaux. Lorsque le vent qui accompagne la pluie ou les embruns souffle sur cette liaison ou encore lorsque les paquets de mer s'abattent sur le textile, les conditions de superposition de la toile sur le chenau se dégradent ou disparaissent par endroits, ce qui provoque l'apparition de zones n'étant plus couvertes et ainsi une diminution de l'étanchéité de la toiture. Ces conditions se produisent aussi sur les bateaux à moteur rapides.A second set of disadvantages is the leakage of the roof. When the sunroofs are closed, peripheral channels are planned to drain runoff water to the outside of the boat. The connection between the canvas and the chenau is realized by the simple superposition of this canvas on this channel, the maintenance from one to the other being favored by the tension of the hoops. When the wind accompanies the rain or the spray blows on this link or when the packets of sea fall on the textile, the conditions of layering of the canvas on the chenau are degraded or disappear in places, causing the appearance of no longer covered and thus a decrease in the waterproofness of the roof. These conditions also occur on fast motor boats.

Une troisième série d'inconvénients est le bruit engendré par les toiles soumises au vent. Par grands vents et/ou fortes vitesses du bateau, les capotes claquent de manière exagérée, provoquant à la fois une usure progressive du tissu allant jusqu'à des déchirures, une fatigue prématurée des éléments de la structure porteurs du tissu et un bruit parasite peu confortable pour l'utilisateur.A third series of disadvantages is the noise generated by the subject fabrics in the wind. In high winds and / or high speeds of the boat, the hoods slam so exaggerated, causing both progressive wear of the fabric and tears, premature fatigue of the structural elements carrying the tissue and a spurious noise uncomfortable for the user.

Enfin, des désordres esthétiques comme des plis et le manque de tension des textiles sont souvent cités comme inconvénients par les possesseurs de bateaux qui y sont particulièrement sensibles.Finally, aesthetic disorders such as folds and the lack of tension of textiles are often cited as inconveniences by boat owners who are particularly sensitive.

Tous ces désagréments proviennent en grande partie de la trop grande souplesse des tissus employés, alors que cette souplesse est justement recherchée pour effectuer les opérations d'ouverture ou de repli des toits ouvrants ou des capotes.All these inconveniences come largely from the excessive flexibility tissues used, whereas this flexibility is precisely sought to perform the opening or closing operations of sunroofs or hoods.

Exposé de l'inventionPresentation of the invention

Un problème principal que se propose de résoudre l'invention consiste à mettre au point un tissu présentant à la fois les propriétés de souplesse pour permettre son pliage et son dépliage facilité et des propriétés de raideur assurant une très bonne tenue du tissu soumis au vent et aux intempéries. A main problem that the invention proposes to solve is to point a fabric with both properties of flexibility to allow its folding and its easy unfolding and stiffness properties ensuring a very good performance of the fabric subject to wind and weather.

Un deuxième problème est de concevoir un tissu présentant une très grande stabilité, de manière à ce que les capotes conservent leurs dimensions, quelles que soient les successions de pliages et de dépliages, les utilisations et les conditions climatiques extérieures, température, humidité, vents ou autres.A second problem is to design a fabric presenting a very large stability, so that the hoods retain their dimensions, whatever successions of folding and unfolding, uses and conditions outdoor climates, temperature, humidity, winds or other.

Un troisième problème posé est celui de réaliser un tissu apte à servir comme protection solaire, mais présentant simultanément une translucidité donnée pour laisser passer une quantité de lumière qui soit agréable pour l'utilisateur.A third problem is that of making a fabric suitable for sun protection, but at the same time having a given translucency to leave pass a quantity of light that is pleasant for the user.

Enfin, le quatrième problème posé est de réaliser un textile permettant de conserver un fini et une planéité impeccables, pour afin d'assurer une esthétique irréprochable au bateau tout au long de sa vie.Finally, the fourth problem is to create a textile allowing maintain an impeccable finish and flatness, to ensure aesthetics irreproachable to the boat throughout his life.

Conformément à la présente invention, un tissu, destiné à la réalisation de toits ouvrants et de capotes, notamment réalisé à partir de fils synthétiques, est caractérisé en ce qu'il comprend une armure :

  • en sens chaíne ou en sens trame, réalisée en fils multifilaments ; et
  • en sens trame ou en sens chaíne, réalisée en fils monofilament, seuls ou en alternance avec des fils multifilaments.
According to the present invention, a fabric intended for producing sunroofs and hoods, in particular made from synthetic threads, is characterized in that it comprises an armor:
  • in warp or weft direction, made of multifilament yarns; and
  • in weft or warp direction, made of monofilament yarns, alone or in alternation with multifilament yarns.

Autrement dit, selon le type d'applications, il peut être intéressant que le tissu possède une capacité de résistance dans les sens chaíne et trame ou bien encore dans un seul de ces deux sens. Les fils monofilament possèdent des propriétés de raideur, tandis que les fils multifilaments sont beaucoup plus déformables. Ainsi réalisé, le tissu possède une excellente souplesse par exemple en chaíne, permettant le pliage et dépliage à volonté sur les arceaux des capotes amovibles, alors que dans le sens de trame le tissu possède beaucoup plus de nerf pour résister aux assauts du vent sur les chenaux, pour éviter de gondoler, pour être moins sensible au claquements, etc.In other words, depending on the type of applications, it can be interesting that the fabric has a resistance in the warp and weft directions or even in a only of these two senses. Monofilament yarns have properties of stiffness, while that the multifilament yarns are much more deformable. Thus realized, the fabric has excellent flexibility eg chain, allowing folding and unfolding at will on the hoops removable hoods, while in the sense of weft the fabric has a lot more nerve to withstand the onslaught of wind on the channels, to avoid warping, to be less sensitive to clicks, etc.

Ainsi, en raison de la présence des fils monofilament, le tissu présente d'autres avantages, tels qu'une meilleure planéité, une plus grande transmission lumineuse à surface par ailleurs identique, ainsi qu'un filigrane beaucoup plus régulier en vision par transparence. De manière intéressante et pour certaines applications ne demandant pas une imperméabilité à l'eau (protection solaire de vérandas, abris, ...), le tissu peut être ajouré de façon à laisser passer sensiblement plus de rayonnements lumineux.Thus, because of the presence of monofilament yarns, the fabric presents other advantages, such as better flatness, greater light transmission at surface otherwise identical, as well as a much more regular watermark in vision by transparency. Interestingly and for some applications not asking waterproof (sun protection of verandas, shelters, ...), the fabric can be perforated so as to let substantially more light radiation.

Les fils multifilaments peuvent favorablement être des fils polymère haute ténacité. Les fils monofilament peuvent être choisis seuls ou en mélange dans le groupe comprenant les fils polymère haute ténacité, les fils de verre, les fils d'acier et d'autres encore. Très préférentiellement, les fils polymère haute ténacité multifilaments et/ou monofilament sont choisis seuls ou en mélange dans le groupe comprenant les fils polyester, les fils de PVC, les fils polyamide, les fils polypropylène, plastifiés ou non, et d'autres encore.Multifilament yarns can favorably be high polymer yarns tenacity. The monofilament yarns can be chosen alone or mixed in the group including high tenacity polymer yarns, glass yarns, steel wires and other again. Very preferably, the multifilament high tenacity polymer yarns and / or monofilament are chosen alone or as a mixture in the group comprising the polyester, PVC yarns, polyamide yarns, polypropylene yarns, plasticized or not, and more besides.

Une des particularités avantageuse des fils de PVC peu plastifié est de permettre de posséder, en plus d'une excellente raideur, le bénéfice de la soudabilité au cours des opérations d'assemblage des textiles par soudure. Cette particularité permet de cautériser les tranches des textiles, d'obturer les passages d'eau et d'empêcher ainsi toutes les migrations par capillarité à l'intérieur des textiles.One of the advantageous features of PVC threads with low plasticity is to allow to possess, in addition to excellent stiffness, the benefit of weldability during textile assembly operations by welding. This feature allows cauterize the slices of textiles, seal the water passages and thus prevent all capillary migrations inside textiles.

Les fils multifilaments peuvent présenter un titre sensiblement compris entre 140 dtex et 1100 dtex. Ce titre peut être de préférence sensiblement égal à 280 dtex. Les fils monofilament peuvent présenter un diamètre sensiblement compris entre 20/100 mm et 40/100 mm. Ce diamètre peut être de préférence sensiblement égal à 30/100 mm. Plus le diamètre du fil monofilament est important, plus il va présenter de raideur.Multifilament yarns may have a heading substantially between 140 dtex and 1100 dtex. This title may preferably be substantially equal to 280 dtex. The monofilament yarns may have a diameter substantially between 20/100 mm and 40/100 mm. This diameter may preferably be substantially equal to 30/100 mm. The larger the diameter of the monofilament wire, the more it will present stiffness.

Le tissu peut posséder en chaíne une contexture sensiblement comprise entre 14 fils/cm et 22 fils/cm. Le tissu peut posséder en trame une contexture sensiblement comprise entre 14 fils/cm et 22 fils/cm Cette contexture peut être de préférence sensiblement égale à 18 fils/cm en chaíne et à 17 fils/cm en trame. Le tissu peut posséder une couche d'enduction sur l'une de ses faces ou sur les deux faces.The fabric can have a chain in a contexture substantially between 14 threads / cm and 22 threads / cm. The fabric may have in frame a substantially between 14 threads / cm and 22 threads / cm This thread can be preferably substantially equal to 18 son / cm chain and 17 son / cm in weft. The fabric can have a coating layer on one of its faces or on both sides.

L'invention sera bien comprise et ses divers avantages et différentes caractéristiques ressortiront mieux lors de la description suivante, de l'exemple non limitatif de réalisation, en référence au dessin schématique annexé, dans lequel la Figure 1 représente une vue en coupe partielle du tissu selon l'invention.The invention will be well understood and its various advantages and different characteristics will stand out better in the following description, in the example not limiting embodiment, with reference to the appended schematic drawing, in which the Figure 1 shows a partial sectional view of the fabric according to the invention.

Exemples de réalisationExamples of realization

Dans un exemple de réalisation, le tissu selon l'invention (1) comprend des fils de chaíne multifilaments (2) et des fils de trame monofilament (3). In an exemplary embodiment, the fabric according to the invention (1) comprises threads of multifilament chain (2) and monofilament weft yarns (3).

Le tissu (1) est réalisé avec :

  • des fils de chaíne en polyester multifilaments (2) haute ténacité, de titre égal à 280 dtex, retordus Z130, et avec une contexture de 18 fils/cm ; et
  • des fils de trame en polyester monofilament (3) haute ténacité, de diamètre 30/100 mm, avec une contexture de 17 fils/cm.
The fabric (1) is made with:
  • high tenacity multifilament polyester yarn (2) of 280 dtex, twisted Z130, and with a thread count of 18 threads / cm; and
  • high tenacity monofilament polyester weft threads (3) with a diameter of 30/100 mm and a thread count of 17 threads / cm.

Le tissu (1) peut ne comprendre en trame que des fils monofilament (3), ou encore être constitué avec une alternance de fils monofilament et de fils multifilaments. Cette alternance, par exemple égale à un fil monofilament pour deux fils multifilaments, peut être extrêmement variable en fonction de la raideur dans le sens trame souhaitée pour le tissu.The fabric (1) may comprise in weft only monofilament threads (3), or be made with an alternation of monofilament yarns and multifilament yarns. This alternation, for example equal to a monofilament yarn for two multifilament yarns, may be extremely variable depending on the stiffness in the desired weft direction for the tissue.

Avec 17 fils/cm de fil monofilament de 30/100 mm, le tissu obtenu (1) est ajouré.With 17 threads / cm of monofilament thread of 30/100 mm, the resulting fabric (1) is perforated.

Le tissu (1) présente sur sa face supérieure (4) une couche d'enduction PVC (6). D'autres matériaux polymères peuvent être envisagés pour l'enduction, tels que des polyuréthannes, des silicones et d'autres encore.The fabric (1) has on its upper face (4) a PVC coating layer (6). Other polymeric materials may be envisaged for coating, such as polyurethanes, silicones and others.

A titre d'exemple, le tissu enduit obtenu (1) présente une masse surfacique sensiblement comprise entre 300 g/m2 et 600 g/m2.For example, the coated fabric obtained (1) has a weight per unit area substantially between 300 g / m 2 and 600 g / m 2 .

Les fils de chaíne (2) et de trame (3) peuvent posséder le même diamètre ou le même titre, lorsque l'on souhaite que le tissu (1) soit uniforme dans les deux sens. Néanmoins, dans d'autres applications, le titre ou le diamètre des fils (2 et 3) peut être différent.The warp (2) and weft (3) can have the same diameter or same way, when it is desired that the fabric (1) is uniform in both directions. Nevertheless, in other applications, the title or the diameter of the wires (2 and 3) can be different.

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 leaving the framework defined by the scope of the set of claims.

D'autres domaines techniques et applications multiples peuvent être aussi concernés pas ces tissus, comme celui de la protection solaire, de stores de type « bannes », des capotes pour véhicules automobiles, ou bien encore d'éléments de toiture souple, de toiles de tentes, etc.Other technical fields and multiple applications can also be not concerned with these fabrics, such as that of sun protection, blinds type "Awnings", hoods for motor vehicles, or even elements of flexible roofing, canvas tents, etc.
