Description

FIL COMPOSITE COMPOSITE YARN
La présente invention concerne un fil composite à usage technique ou industriel, pouvant être assemblé en tous types de structures textiles, notamment surfaces textiles appropriées, pour répondre à toutes applications ou spécifications particulières, par exemple pour la fabrication de stores ou rideaux.The present invention relates to a composite yarn for technical or industrial use, which can be assembled into all types of textile structures, in particular suitable textile surfaces, to meet any particular application or specification, for example for the manufacture of blinds or curtains.
Dans l'art antérieur, on connaît par le document US-A-4 127 698 la réalisation de fibres composites ignifuges comprenant un mélange de deux fibres. La première est désignée fibre matrice et est à base de PVC et PVA partiellement acétalisé, et comporte en outre un agent ignifugeant inorganique, constitué d'un oxyde d'étain hydraté, et un oxyde d'antimoine hydraté. La deuxième fibre est à base de polyester, acrylique ou coton.In the prior art, document US-A-4 127 698 discloses the production of flame retardant composite fibers comprising a mixture of two fibers. The first is designated matrix fiber and is based on partially acetalized PVC and PVA, and further comprises an inorganic flame retardant, consisting of a hydrated tin oxide, and a hydrated antimony oxide. The second fiber is based on polyester, acrylic or cotton.
Dans le document EP-A-0 385 025 on décrit la fabrication d'un fil composite comportant une âme en fibres de verre, et une gaine obtenue par filage de fibres à basse température de fusion, par exemple en coton.Document EP-A-0 385 025 describes the manufacture of a composite yarn comprising a glass fiber core, and a sheath obtained by spinning fibers at low melting temperature, for example cotton.
Toutefois, ces documents concernent essentiellement des fils obtenus par filage de mélanges de fibres, et ne conviennent pas aux applications envisagées ci-après. Par ailleurs, on connaît déjà, et la Demanderesse fabrique et vend des fils composites techniques, comprenant :However, these documents essentially relate to yarns obtained by spinning fiber mixtures, and are not suitable for the applications envisaged below. Furthermore, we already know, and the Applicant manufactures and sells technical composite yarns, comprising:
- une âme comportant un fil continu, par exemple un fil de verre ; - et une gaine enduite comportant une matrice plastique, constituée par au moins un matériau polymère chloré, par exemple un polychlorure de vinyle ;- a core comprising a continuous wire, for example a glass wire; - And a coated sheath comprising a plastic matrix, constituted by at least one chlorinated polymeric material, for example a polyvinyl chloride;
- une charge minérale ignifugeante incorporée et distribuée dans ladite matrice ; - et un plastifiant. Préférentiellement, mais de manière non exclusive, un tel fil est obtenu par enduction de l'âme avec un plastisol comprenant le matériau polymère chloré, par exemple polychlorure de vinyle, et le plastifiant, puis par gélification du plastisol autour de l'âme.- a flame retardant mineral filler incorporated and distributed in said matrix; - and a plasticizer. Preferably, but not exclusively, such a wire is obtained by coating the core with a plastisol comprising the chlorinated polymer material, for example polyvinyl chloride, and the plasticizer, then by gelling the plastisol around the core.
Les tissus techniques obtenus avec de tels fils, et lorsqu'ils sont mis en oeuvre dans différents environnements, notamment pour l'aménagement tant intérieur qu'extérieur d'immeubles ou constructions, par exemple à titre de stores, sont soumis à des exigences de comportement au feu, définies par des réglementations et/ou procédures d'homologation ou autorisation, nationales ou internationales.The technical fabrics obtained with such threads, and when they are used in different environments, in particular for the interior and exterior fittings of buildings or constructions, for example as blinds, are subject to fire behavior, defined by national or international regulations and / or approval or authorization procedures.
Ainsi, la réglementation applicable à de tels tissus en République Fédérale d'Allemagne définit différents classements, caractérisés notamment par la longueur de l'échantillon détruite par le feu, et par la température des fumées de combustion, et identifiés par les lettres Bl à B3, la lettre Bl caractérisant le meilleur comportement au feu accessible par un matériau comprenant des matières organiques.Thus, the regulations applicable to such fabrics in the Federal Republic of Germany define different classifications, characterized in particular by the length of the sample destroyed by fire, and by the temperature of the combustion fumes, and identified by the letters Bl to B3 , the letter Bl characterizing the best behavior in fire accessible by a material comprising organic matters.
Et la réglementation applicable en France définit quant à elle, également différents classements, d'une part caractérisés notamment par l'émission de fumées et identifiés par les lettres FO à F5, F3 étant le meilleur comportement accessible par un matériau contenant un polymère halogène, et d'autre part caractérisés notamment par la température d'inflammation résiduelle du tissu, et identifiés par les lettres MO à M4, la lettre Ml identifiant le meilleur comportement au feu généralement accessible par un matériau comprenant des matières organiques.And the regulations applicable in France also define different classifications, on the one hand characterized in particular by the emission of smoke and identified by the letters FO to F5, F3 being the best behavior accessible by a material containing a halogenated polymer, and on the other hand characterized in particular by the residual ignition temperature of the fabric, and identified by the letters MO to M4, the letter Ml identifying the best behavior in fire generally accessible by a material comprising organic materials.
Aujourd'hui, avec les fils composites définis précédemment, les tissus techniques obtenus présentent un comportement au feu ayant une certaine limite, illustrée par le fait que de tels tissus n'ont jamais pu obtenir, sans traitement chimique postérieur à leur tissage, le classement Bl de la réglementation allemande, conjointement avec le classement Ml de la réglementation française. La principale raison des limites précédemment constatées tient évidemment à la nature organique de certains constituants du fil composite, notamment le matériau polymère chloré, le plastifiant, voire certains additifs d'enduction. Différentes tentatives ont été faîtes pour améliorer intrinsèquement le comportement au feu, de ces fils composites, par exemple en utilisant des plastifiants particuliers, comme des phosphates organiques. Malheureusement, l'utilisation de tels plastifiants détériore les caractéristiques de mise en oeuvre (souplesse, pouvoir glissant, etc..) de ces fils, ce qui nuit à leur tissage postérieur, et rend ce dernier plus difficile. Par ailleurs, l'incorporation de tels plastifiants augmente l'indice de fumée. II n'est pas possible, non plus, d'augmenter de manière significative la proportion pondérale de la charge ignifugeante, sauf à détériorer comme précédemment les caractéristiques de mise en oeuvre du fil composite.Today, with the composite yarns defined above, the technical fabrics obtained exhibit a fire behavior with a certain limit, illustrated by the fact that such fabrics have never been able to obtain, without chemical treatment subsequent to their weaving, the classification Bl of the German regulations, together with the classification Ml of the French regulations. The main reason for the limits noted above is obviously due to the organic nature of certain constituents of the composite yarn, in particular the chlorinated polymer material, the plasticizer, or even certain coating additives. Various attempts have been made to intrinsically improve the fire behavior of these composite yarns, for example by using particular plasticizers, such as organic phosphates. Unfortunately, the use of such plasticizers deteriorates the processing characteristics (flexibility, sliding power, etc.) of these threads, which harms their posterior weaving, and makes the latter more difficult. Furthermore, the incorporation of such plasticizers increases the smoke index. Nor is it possible to significantly increase the proportion by weight of the flame-retardant filler, unless, as before, the processing characteristics of the composite yarn are deteriorated.
S•agissant des performances de la charge ignifugeante proprement dite, différents documents ont proposé divers composés ou diverses compositions, susceptibles d'améliorer le comportement au feu des matrices plastiques dans lesquelles la charge ignifugeante est incorporée, sans que l'application ou la mise en forme de la matière plastique ignifugée, par exemple sous forme de fil, soit précisée.S • acting on the performance of the fire-retardant filler proper, various documents have proposed various compounds or various compositions, capable of improving the fire behavior of plastic matrices in which the fire-retardant filler is incorporated, without the application or setting form of the flame-retardant plastic, for example in the form of wire, is specified.
Ainsi, selon le document JP-A-58185637, pour une matrice à base de polychlorure de vinyle, on a proposé une charge ignifugeante comprenant un polyéthylène chloré, un composé choisi parmi notamment les oxydes et/ou hydroxydes d'antimoine, et d'aluminium, et préférentiellement un autre composé choisi parmi certains sels de zinc, dont le borate de zinc.Thus, according to document JP-A-58185637, for a matrix based on polyvinyl chloride, a flame retardant filler has been proposed comprising a chlorinated polyethylene, a compound chosen from in particular the oxides and / or hydroxides of antimony, and of aluminum, and preferably a another compound chosen from certain zinc salts, including zinc borate.
Et conformément au document FR-A-2 448 554, toujours pour une matrice à base de polychlorure de vinyle, incorporant par ailleurs un stabilisant, un plastifiant constitué par un ester phosphorique, et une charge d'hydroxyde d'alumine, on a proposé une charge ignifugeante comprenant un oxyde d'antimoine, éventuellement associé à un borate de zinc. Aucune des charges ignifugeantes précédemment proposées ne convient pour améliorer le comportement au feu d'un fil composite tel que précédemment considéré.And in accordance with document FR-A-2 448 554, still for a matrix based on polyvinyl chloride, incorporating moreover a stabilizer, a plasticizer constituted by a phosphoric ester, and a filler of aluminum hydroxide, we have proposed a flame retardant filler comprising an antimony oxide, optionally combined with a zinc borate. None of the flame retardant fillers previously proposed is suitable for improving the fire behavior of a composite wire as previously considered.
La présente invention a pour objet un fil composite, tel que précédemment défini, présentant globalement et intrinsèquement un comportement au feu amélioré, exprimé conjointement par une diminution substantielle de la température des fumées de combustion et par un abaissement substantiel du seuil d'inflammation résiduelle des différents tissus obtenus avec le fil selon l'invention, de telle sorte qu'en particulier de tels tissus puissent satisfaire à la fois aux classements actuels Bl de la réglementation allemande (norme DIN N04102 Teil 1) , et Ml et F3 de la réglementation française (norme NFP 92503) , et tout cela sans nuire aux caractéristiques de mise en oeuvre du même fil, requises pour le tissage.The subject of the present invention is a composite wire, as defined above, having globally and intrinsically improved fire behavior, expressed jointly by a substantial decrease in the temperature of the combustion fumes and by a substantial lowering of the residual ignition threshold of the different fabrics obtained with the yarn according to the invention, so that in particular such fabrics can satisfy both the current classifications Bl of the German regulations (standard DIN N04102 Teil 1), and Ml and F3 of the French regulations (standard NFP 92503), and all this without harming the processing characteristics of the same yarn, required for weaving.
Conformément à la présente invention, on a découvert que les objectifs précités pouvaient être satisfaits en combinant deux caractéristiques essentielles, à savoir :In accordance with the present invention, it has been discovered that the above-mentioned objectives can be satisfied by combining two essential characteristics, namely:
(a) le choix d'une composition ternaire pour la charge ignifugeante, associant : un composé oxygéné d'antimoine, par exemple du trioxyde (Sb203) ou pentoxyde d'antimoine ; - un oxyde métallique hydraté dont le métal est choisi dans le groupe constitué par l'aluminium, le magnésium, l'étain, le zinc, et le plomb, par exemple hydrate d'alumine (AI2O3.3H2O) ; et un borate de zinc, hydraté ou non, par exemple (2ZnO.3B203.7/2 H20) ; (b) avec la composition ternaire précitée, le maintien de la composition pondérale totale en matières inorganiques du fil composite, y compris l'âme, dans une fourchette comprise entre 4 % et 65 %.(a) the choice of a ternary composition for the flame retardant charge, combining: an oxygenated antimony compound, for example trioxide (Sb 2 0 3 ) or antimony pentoxide; - a hydrated metal oxide, the metal of which is chosen from the group consisting of aluminum, magnesium, tin, zinc, and lead, for example alumina hydrate (AI2O3.3H2O); and a zinc borate, hydrated or not, for example (2ZnO.3B 2 0 3 .7 / 2 H 2 0); (b) with the aforementioned ternary composition, maintaining the total weight composition in inorganic matter of the composite yarn, including the core, in a range between 4% and 65%.
Préférentiellement, la composition pondérale totale en matières inorganiques de la gaine est comprise entre 4 % et 15 %.Preferably, the total weight composition in inorganic matter of the sheath is between 4% and 15%.
Avantageusement, la charge ignifugeante consiste en ladite composition ternaire.Advantageously, the flame retardant charge consists of said ternary composition.
A titre de matériau polymère chloré, on peut utiliser conformément à l'invention, toute résine PVC susceptible d'être plastifiée, et notamment pouvant être de ce fait mise en oeuvre sous forme de plastisol.As chlorinated polymeric material, it is possible to use, in accordance with the invention, any PVC resin capable of being plasticized, and in particular able therefore to be used in the form of plastisol.
Préférentiellement, les polychlorures de vinyle selon la présente invention ont un K WERT compris entre 65 et 75.Preferably, the polyvinyl chlorides according to the present invention have a K WERT of between 65 and 75.
Par matériau polymère chloré, on entend, ou un polymère chloré pur ou un copolymère de chlorure de vinyle copolymérisé avec d'autres monomères, ou encore un polymère chloré qui est allié avec d'autres polymères. Parmi les monomères qui peuvent être copolymérisés avec le chlorure de vinyle, on citera notamment des oléfines comme par exemple l'éthylène, des esters vinyliques d'acides carboxyliques saturés, comme l'acétate de vinyle ou le butyrate de vinyle ; des dérivés vinyliques halogènes comme, par exemple, le chlorure de vinylidene, des esters d'acide acrylique ou méthacrylique comme l'acrylate de butyle.By chlorinated polymer material is meant either a pure chlorinated polymer or a vinyl chloride copolymer copolymerized with other monomers, or a chlorinated polymer which is alloyed with other polymers. Among the monomers which can be copolymerized with vinyl chloride, mention will be made in particular of olefins such as, for example, ethylene, vinyl esters of saturated carboxylic acids, such as vinyl acetate or vinyl butyrate; halogenated vinyl derivatives such as, for example, vinylidene chloride, esters of acrylic or methacrylic acid such as butyl acrylate.
A titre de polymère chloré, on citera par exemple le polychlorure de vinyle mais aussi les PVC surchlorés, les polychlorures de vinylidene et les polyoléfines chlorées. De manière préférentielle, mais non exclusive, le matériau polymère chloré selon la présente invention a une teneur pondérale en halogène comprise entre 50 et 70 %.By way of chlorinated polymer, mention may be made, for example, of polyvinyl chloride but also superchlorinated PVCs, polyvinylidene chlorides and chlorinated polyolefins. Preferably, but not exclusively, the chlorinated polymer material according to the present invention has a halogen content by weight of between 50 and 70%.
S'agissant du fil continu formant ou compris dans l'âme du fil composite, il peut être lui-même constitué par un ou plusieurs filaments continus. Sa nature chimique peut être organique, par exemple en polyester, ou inorganique, par exemple en verre ou silice, étant entendu que sa température de fusion doit être supérieure à celle de mise en oeuvre du matériau polymère de la matrice constituant la gaine ou enveloppe du fil composite.As regards the continuous wire forming or included in the core of the composite wire, it may itself be constituted by one or more continuous filaments. Its chemical nature can be organic, for example polyester, or inorganic, for example glass or silica, it being understood that its melting temperature must be higher than that of the polymeric material of the matrix constituting the sheath or envelope of the composite wire.
D'autres charges peuvent être incorporées et distribuées dans la matrice de la gaine, en plus de la charge ignifugeante, par exemple une charge pigmentaire et/ou une charge stabilisante. En pareil cas, la composition pondérale totale du fil composite, en matières inorganiques, se trouve évidemment modifiée ou affectée, également par le contenu en matières inorganiques de ces charges supplémentaires. Grâce à l'invention, il demeure possible de recourir à des plastifiants traditionnels pour la matrice plastique, par exemple comprenant au moins un phtalate organique, et par conséquent de ne pas compromettre les propriétés de mise en oeuvre du fil, vis-à-vis de son tissage ultérieur.Other fillers can be incorporated and distributed in the sheath matrix, in addition to the flame retardant filler, for example a pigment filler and / or a stabilizing filler. In such a case, the total weight composition of the composite yarn, in inorganic matter, is obviously modified or affected, also by the inorganic matter content of these additional fillers. Thanks to the invention, it remains possible to use traditional plasticizers for the plastic matrix, for example comprising at least one organic phthalate, and therefore not to compromise the processing properties of the wire, vis-à-vis of its subsequent weaving.
L'invention permet aussi de limiter pondéralement la charge ignifugeante, dans des proportions n'excédant pas 65 % de la matrice plastique, ce qui favorise un bon tissage du fil selon l'invention. Au-delà de 65 %, on assiste à un poudrage de la gaine, altérant les propriétés notamment mécaniques du fil composite.The invention also makes it possible to limit the flame-retardant load by weight, in proportions not exceeding 65% of the plastic matrix, which promotes good weaving of the thread according to the invention. Above 65%, there is dusting of the sheath, altering the notably mechanical properties of the composite wire.
En restant avec un fil composite obtenu par enduction, la présente invention apporte donc un comportement au feu du même fil, très proche de celui d'un fil de nature inorganique. Et les tissus obtenus avec un fil composite selon l'invention n'ont pas besoin d'un traitement postérieur pour améliorer leur comportement au feu.By remaining with a composite wire obtained by coating, the present invention therefore provides a fire behavior of the same wire, very close to that of a wire of inorganic nature. And the fabrics obtained with a composite yarn according to the invention do not need a subsequent treatment to improve their fire behavior.
Il résulte aussi des essais de la Demanderesse que les fils composites selon la présente invention ont une très bonne tenue à la lumière et aux intempéries. Préférentiellement :It also results from the Applicant's tests that the composite yarns according to the present invention have very good resistance to light and weathering. Preferably:
- la composition pondérale en plastifiant d'un fil composite selon l'invention n'excède pas 40 %, et est de préférence comprise entre 10 et 20 % ; au-delà de 35 % de plastifiant, ce dernier exsude de la matrice de l'enveloppe ou gaine ;- The composition by weight of plasticizer of a composite yarn according to the invention does not exceed 40%, and is preferably between 10 and 20%; beyond 35% of plasticizer, the latter exudes from the matrix of the envelope or sheath;

La présente invention s'appuie sur le protocole expérimental suivant.The present invention is based on the following experimental protocol.
On a tout d'abord formulé un plastisol comprenant le matériau polymère et un plastifiant, selon la composition pondérale suivante :First of all, a plastisol comprising the polymer material and a plasticizer was formulated, according to the following weight composition:
- 60 à 65 % d'une ou plusieurs résines de polychlorure de vinyle (référence commerciale ECKAVYL EF701 de la Société ATOCHEM) ;- 60 to 65% of one or more polyvinyl chloride resins (commercial reference ECKAVYL EF701 from the company ATOCHEM);
- 20 à 30 % d'un phtalate d'isononyle (référence commerciale JAYFLEX DINP de la Société EXXON) ;- 20 to 30% of an isononyl phthalate (commercial reference JAYFLEX DINP from the company EXXON);
- additifs divers, pour le complément, dont stabilisant thermique inorganique (de 1,5 à 2 %) .- various additives, for the complement, including inorganic thermal stabilizer (from 1.5 to 2%).
A ce plastisol a été incorporée une charge ignifugeante ternaire, associant à parts pondérales égales :To this plastisol has been incorporated a ternary flame retardant filler, associating in equal weight shares:
- du trioxyde d'antimoine, Sb203 ;- antimony trioxide, Sb 2 0 3 ;
- de l'hydrate d'alumine, A1203.3H20 ;- alumina hydrate, A1 2 0 3 .3H 2 0;
- du borate de zinc (2Zn0.3B2O3.7/2 H20) , noté ci-après BoZn. Puis, on enduit une âme en fil de verre avec le plastisol chargé, pour obtenir un fil composite selon la présente invention.- zinc borate (2Zn0.3B 2 O 3 .7 / 2 H 2 0), noted below BoZn. Then, a glass wire core is coated with the loaded plastisol, to obtain a composite wire according to the present invention.
Et ce fil est tissé selon différentes armures, ou spécifications, précisées ci-après.And this thread is woven according to different weaves, or specifications, specified below.
Conformément au tableau ci-après où Mi et Bl désignent les niveaux de classement le plus élevé, respectivement selon la réglementation allemande et selon la réglementation française, pour un matériau organique, on a tout d'abord découvert que l'association ternaire des trois composés ci-dessus, était nécessaire à l'obtention conjointe du classement Ml et du classement Bl, et ceci pour les tissus obtenus avec un fil selon la présente invention, avec les armures suivantes :In accordance with the table below where Mi and Bl designate the highest classification levels, respectively according to German regulations and according to French regulations, for an organic material, it was first discovered that the ternary association of the three compounds above, was necessary to obtain the Ml classification and the Bl classification jointly, and this for the fabrics obtained with a thread according to the present invention, with the following weaves:
- satiné - contexture 18/14- satin - texture 18/14
- natté - contexture 14/14- braided - texture 14/14
Puis différents fils ont été obtenus, avec des compositions pondérales (en %) respectivement différentes, en fonction du titre désiré, selon le tableau ci-après : Then different yarns were obtained, with weight compositions (in%) respectively different, depending on the desired titer, according to the table below:
(1) les pourcentages sont exprimés par rapport au poids total de l'âme en verre et de l'enveloppe, ramené à(1) the percentages are expressed relative to the total weight of the glass core and the envelope, reduced to
100 % ;100%;
(2) en tenant compte de la présence éventuelle de charges autres qu'ignifugeantes, par exemple pigmentaires.(2) taking into account the possible presence of charges other than flame retardants, for example pigments.
Un fil composite selon la présente invention peut être intégré dans, ou assemblé selon toutes structures textiles requises, bidimensionnelles (nappes, tissus, etc... ) ou tridimensionnelles (tresses par exemple) .A composite yarn according to the present invention can be integrated into, or assembled according to any required textile structure, two-dimensional (tablecloths, fabrics, etc.) or three-dimensional (braids for example).
Le fil composite peut tout d'abord être coupé et divisé en fils élémentaires, pouvant être entremêlés et fixés les uns aux autres, sous forme de structures textiles non tissées, mats par exemple. La fixation des fils élémentaires entremêlés peut être obtenue par imprégnation avec une substance adhésive appropriée, ou encore par thermo-fusion du matériau polymère de la gaine. Le fil composite peut ensuite être assemblé sur lui-même, dans toutes structures textiles tricotées appropriées, mais il peut être assemblé avec d'autres fils, selon la présente invention ou non, pour constituer bidimensionnelles ; dans ce dernier cas, il peut s'agir de grilles dans lesquelles les fils selon la présente invention sont entrecroisés et fixés avec d'autres fils, selon la présente invention ou non, et de tissus, dans lesquels les fils composites selon l'invention sont tissés avec d'autres fils de chaîne et/ou trame, également selon l'invention ou non. Une application toute particulière de la présente invention concerne l'obtention de tissus techniques, destinés à la réalisation ou fabrication de stores ou rideaux tant intérieurs qu'extérieurs.The composite yarn can firstly be cut and divided into elementary yarns, which can be intertwined and fixed to each other, in the form of non-woven textile structures, for example matt. The fixing of the intermingled elementary wires can be obtained by impregnation with an appropriate adhesive substance, or by thermofusion of the polymer material of the sheath. The composite yarn can then be assembled on itself, in any suitable knitted textile structure, but it can be assembled with other yarns, according to the present invention or not, to constitute two-dimensional; in the latter case, it may be grids in which the wires according to the present invention are interlaced and fixed with other wires, according to the present invention or not, and fabrics, in which the composite threads according to the invention are woven with other warp and / or weft threads, also according to the invention or not. A very particular application of the present invention relates to obtaining technical fabrics, intended for the realization or manufacture of blinds or curtains both inside and outside.
Pour l'obtention de stores, les fils obtenus selon le protocole expérimental précité ont été tissés selon les armures suivantes ou spécifications suivantes, à titre d'exemple : satiné - contexture 18/14 natté - contexture 14/14 Après essais au feu, tous ces tissus ont montré qu'ils satisfaisaient, et à la réglementation allemande avec le classement Bl, et à la réglementation française avec le classement Ml et F3. To obtain blinds, the threads obtained according to the aforementioned experimental protocol were woven according to the following weaves or following specifications, for example: satin - 18/14 weave texture - 14/14 texture After fire tests, all these fabrics have shown that they meet both the German regulations with the Bl classification and the French regulations with the Ml and F3 classification.
