Definitions
- the invention relates to polypropylene-based monofilaments having improved properties, including improved abrasion resistance, a method of making these monofilaments and their use.
- the invention relates more particularly polypropylene-based monofilaments, the polypropylene being obtained by polymerization of propylene in the presence of a metallocene catalyst.
- Two-dimensional polypropylene textile articles are of great interest as chemically and mechanically resistant filter media for filtration in the chemical, pharmaceutical and food industries.
- filter media for filtration in the chemical, pharmaceutical and food industries.
- particularly relatively coarse monofilaments having a diameter greater than 0.050 mm are required.
- Pure polypropylene monofilaments have the disadvantage of forming a lot of dust due to the low resistance of this substance to abrasion during the weaving process.
- the problem of abrasion is also known for other thermoplastics.
- abrasion resistant monofilaments are obtained using 70 to 99% by weight of fibrogenic polymer and 1 to 30% by weight of a polyethylene / polypropylene rubber, modified with maleic anhydride. , and other additives.
- the examples are limited, as regards the fibrogenic polymer, polyamide 6 and polyethylene terephthalate, and a copolyamide of PA66 and PA6. The spinning speeds are not specified.
- the requests WO 02/086207 and WO 03/048434 disclose polypropylene monofilaments comprising additives.
- the polypropylene used to manufacture the monofilaments has a melt viscosity index greater than or equal to 6 g for 10 minutes. These monofilaments have good abrasion resistance properties.
- the problem of the invention consists in providing polypropylene-based wound monofilaments which are more resistant to abrasion than the monofilaments known from the prior art. Another problem of the invention is to obtain polypropylene-based coiled monofilaments, which have improved resistance to abrasion during weaving.
- the problem is solved according to the invention in particular by using, for the manufacture of monofilaments, a polypropylene obtained by polymerization of propylene in the presence of a metallocene catalyst.
- Polypropylenes conventionally used in the manufacture of monofilaments are isotactic polypropylenes.
- metallocene is meant a coordination compound (ferrocene, cobaltocene, nickelocene, titanocene, zirconocene, uranocene, etc.) obtained as a cyclopentadienyl derivative of a transition metal.
- Metallocene catalysts are known to those skilled in the art. These metallocene catalysts are different from the catalysts known as Ziegler-Natta catalysts.

- the abrasion value corresponds to the result of the formula described below in the experimental part, calculated for a length of fabric of 300 m.
- the monofilaments have an abrasion of less than 0.014%. Indeed, when the abrasion is greater than 0.014%, irregularities can occur during weaving, due to a too rapid fouling of combs. This may require shortening the intervals between cleanings, which decreases the productivity of the craft.
- wound monofilaments obtainable according to the process of the invention preferably have an abrasion less than or equal to 0.005%.
- the monofilaments have a strength of at least 50 cN / tex, for an elongation corresponding to the maximum tensile stress (elongation at break) of at least 20%. Indeed, a strength of less than 50 cN / tex has the disadvantage of multiplying the breakages of yarn during the weaving process.

Description
- L'invention concerne des monofilaments à base de polypropylène présentant des propriétés améliorées, notamment une résistance à l'abrasion améliorée, un procédé de fabrication de ces monofilaments et leur utilisation. L'invention concerne plus particulièrement des monofilaments à base de polypropylène, le polypropylène étant obtenu par polymérisation de propylène en présence d'un catalyseur métallocène.
- Les articles textiles à deux dimensions en polypropylène sont d'un grand intérêt, en tant que moyens de filtration résistant chimiquement et mécaniquement, pour la filtration dans les industries chimique, pharmaceutique et alimentaire. Dans ce domaine, on demande en particulier des monofilaments relativement grossiers, qui possèdent un diamètre supérieur à 0,050 mm.
- Les monofilaments de polypropylène pur présentent l'inconvénient de former beaucoup de poussières par suite de la faible résistance de cette substance à l'abrasion lors du processus de tissage. Le problème de l'abrasion est connu également pour d'autres thermoplastiques. C'est ainsi que l'
EP-A2-0 784 107 cite des monofils filés à l'état fondu, de polyamide, polyester ou polypropylène, destinés aux toiles des machines à papier et aux fils des coupe-bordures. Selon ce brevet, on obtient des monofilaments résistant à l'abrasion à l'aide de 70 à 99 % en poids de polymère fibrogène et de 1 à 30 % en poids d'un caoutchouc de polyéthylène/polypropylène, modifié à l'anhydride maléique, et d'autres additifs. Les exemples se limitent toutefois, en ce qui concerne le polymère fibrogène, au polyamide 6 et au polyéthylènetéréphtalate, ainsi qu'à un copolyamide de PA66 et de PA6. Les vitesses de filage ne sont pas précisées. - Grâce à l'
EP-A-1059370 , on connaît également un procédé de fabrication de multifilaments de polypropylène destinés à des applications textiles. Comme matériau de départ, on utilise un polypropylène isotactique, dont l'indice de viscosité en fondu est supérieur à 19 g pour 10 minutes. On trouve décrits des multifilaments FOY (Fully Oriented Yarns [= fils totalement orientés]) de 10 dpf (= denier par filament) [0,03953 mm] et POY (Partially Oriented Yarns [= fils partiellement orientés]) de 2 dpf (= deniers par fibre) [0,01768 mm]. En ce qui concerne les fils fabriqués, seules figurent des indications générales. On ne trouve pas décrits de monofilaments. - Les demandes
WO 02/086207 WO 03/048434 - Le problème de l'invention consiste à mettre à disposition des monofilaments embobinés à base de polypropylène, plus résistants à l'abrasion que les monofilaments connus de l'art antérieur. Un autre problème de l'invention consiste à obtenir des monofilaments embobinés à base de polypropylène, qui présentent une résistance améliorée vis-à-vis de l'abrasion lors du tissage.
- Le problème est résolu selon l'invention notamment grâce à la mise en oeuvre, pour la fabrication des monofilaments, d'un polypropylène obtenu par polymérisation de propylène en présence d'un catalyseur métallocène.
- Les polypropylènes conventionnellement utilisés dans la fabrication des monofilaments sont des polypropylènes isotactiques.
- Par métallocène on entend un composé de coordination (ferrocène, cobaltocène, nickelocène, titanocène, zirconocène, uranocène etc.) obtenu comme dérivé cyclopentadiénylique d'un métal de transition.
- Les catalyseurs métallocène sont connus de l'homme du métier. Ces catalyseurs métallocène sont différents des catalyseurs connus sous le nom de catalyseurs Ziegler-Natta.
- Les catalyseurs métallocène de l'invention peuvent être supportés ou non.
- Les monofilaments de l'invention présentent avantageusement une abrasion inférieure ou égale à 0.014%.
- L'abrasion des monofilaments est déterminée par mesure gravimétrique de la quantité de duvet produite lors de la fabrication d'une longueur de tissu de 300m, selon la méthode décrite ci-dessous dans la partie expérimentale. La valeur d'abrasion correspond au résultat de la formule décrite ci-dessous dans la partie expérimentale, calculée pour une longueur de tissu de 300 m.
- Il est particulièrement avantageux que les monofilaments présentent une abrasion de moins de 0,014 %. En effet, lorsque l'abrasion est supérieure à 0,014 %, il peut se produire des irrégularités lors du tissage, dues à un encrassement trop rapide des peignes. Cela peut obliger à raccourcir les intervalles entre nettoyages, ce qui diminue la productivité du métier.
- Les monofilaments embobinés obtenables selon le procédé de l'invention présentent de préférence une abrasion inférieure ou égale 0.005%.
- Il est approprié que les monofilaments possèdent une résistance d'au moins 50 cN/tex, pour un allongement correspondant à l'effort de traction maximal (allongement à la rupture) au moins égal à 20 %. En effet, une résistance inférieure à 50 cN/tex présente l'inconvénient de multiplier les casses de fil lors du processus de tissage.
- Les monofilaments embobinés obtenables selon le procédé de l'invention présentent avantageusement une constante mécanique supérieure ou égale à 285.
- Le diamètre des monofilaments embobinés obtenables selon le procédé de l'invention est supérieur ou égal à 0.05mm.
- Les monofilaments embobinés obtenables selon le procédé de l'invention peuvent comprendre des additifs. Les monofilaments comprennent avantageusement de 0.01 à 20% en poids d'additif par rapport au poids de polypropylène.
- Avantageusement, il est approprié d'utiliser comme additif un copolymère de polypropylène/polyéthylène possédant un point de fusion ≥ 140 °C. Avantageusement cet additif est présent dans une proportion de 1 à 20% en poids par rapport au poids de polypropylène.
- L'invention concerne donc un procédé de fabrication des monofilaments de l'invention, comprenant les étapes de filage du polypropylène en fondu par extrusion, étirage et bobinage, et une bobine obtenable selon ce procédé.
- Les monofilaments à base de polypropylène de l'invention peuvent être obtenus à partir de méthodes classiques de filage. Ils sont généralement obtenus par filage en fondu par extrusion, refroidissement dans un bain d'eau lorsque le titre des monofilaments est supérieur ou égal à 0.05mm, étirage et bobinage. Lorsque les monofilaments de l'invention comprennent un additif, l'additif est généralement ajouté au polypropylène en
- Les monofilaments embobinés obtenables selon le procédé selon l'invention conviennent particulièrement à la fabrication d'articles techniques à deux dimensions, et notamment à la fabrication de tels articles dans le domaine de la filtration. Ces articles, lorsqu'ils sont destinés à la filtration, notamment dans les industries chimique, pharmaceutique et alimentaire, sont de préférence des tissus.
- On va maintenant décrire l'invention de façon plus détaillée, à l'aide d'exemples.
- Comme polymère, on utilise lors des essais différents polypropylènes, obtenus par polymérisation de propylène en présence d'un catalyseur métallocène, l'indice de viscosité des polypropylènes en fondu (MFI) 230°C/2,16kg étant variable.
- Polymère A : polypropylène commercialisé par la société Atofina sous la référence MR 15 2002®, présentant un indice de viscosité en fondu (MFI) 230°C/2,16kg de 15 g/10 min

- On met en oeuvre chaque fois 300 kg de granulé de polypropylène, en utilisant des fûts de 25 kg
- Les granulés de polypropylène et éventuellement les granulés d'additif sont admis directement dans l'extrudeuse et fondus.
