A melt-extruded monofilament comprises plastic material with poly-trimethylene terephthalate (PTMT) as the main component. Also claimed is a paper machine cover containing this melt-extruded monofilament. Preferably the material may also contain up to 45 wt.% polyurethane (PU) to increase its abrasion resistance, especially elastomeric PU, and up to 5 wt.% hydrolysis stabiliser. The monofilament has a cross-sectional area of 0.02-3.5 mm<2>, and may have a circular cross-section with a diameter of 0.08-1 mm or a square, rectangular, oval, clover-leaf or dog's bone cross- section.

Description

Die Erfindung betrifft ein schmelzextrudiertes Monofilament für den Einsatz in technischen Textilien, insbesondere in Papiermaschinenbespannungen, das im wesentlichen aus einem Kunststoffmaterial besteht.The invention relates to a melt-extruded monofilament for use in technical textiles, especially in paper machine clothing, essentially made of a plastic material consists.

Derartige schmelzextrudierte Monofilamente haben eine hohe Festigkeit und werden daher bevorzugt in festigkeitstragenden Strukturen wie technischen Geweben und Gewirken und insbesondere in Bespannungen für Papiermaschinen eingesetzt.Such melt-extruded monofilaments have high strength and are therefore preferred in strength-bearing Structures such as technical fabrics and knitted fabrics and in particular used in clothing for paper machines.

Derzeit werden in erster Linie Monofilamente auf der Basis von Polyethylenterephtalat (PET) verwendet, die in besonderen Fällen zur Erhöhung der Abtriebsfestigkeit einen Anteil thermoplastischen Polyurethans (PU) aufweisen, wie sie beispielsweise aus der EP 0 387 395 B1 bekannt sind. Diese Monofilamente auf PET-Basis haben sich in der Praxis durchaus bewährt, jedoch gestaltet sich ihre Herstellung oft problematisch. Der Grund dafür liegt darin, daß das Extrudieren von Monofilamenten aus Polyethylenterephtalat und Polyurethan und deren spätere Fixierung im Gewebe bei hohen Temperaturen stattfindet, was aus verschiedenen Gründen oftmals unerwünscht ist. Insbesondere können die zum Einsatz kommenden hohen Temperaturen auch für das Polyurethan schädigend wirken. Diesen Schädigungen kann nur durch aufwendige Maßnahmen und auch nur zum Teil entgegengewirkt werden. Monofilamente aus polypropylenterephthalat sind z.B. bekannt aus EP-A-0 520 162 und JP-A-0 812 052. Aufgabe der Erfindung ist es daher, ein Monofilament für textile Materialien der eingangs genannten Art zu schaffen, das auf einfache Weise und bei niedrigeren Temperaturen extrudierbar und später fixierbar ist.Currently, monofilaments based on Polyethylene terephthalate (PET) used in special cases a portion of thermoplastic to increase the abrasion resistance Have polyurethane (PU), such as are known from EP 0 387 395 B1. These monofilaments on PET bases have proven themselves in practice, but designed their manufacture is often problematic. The reason for this lies in the fact that the extrusion of monofilaments Polyethylene terephthalate and polyurethane and their later fixation in tissue at high temperatures, which is different Reasons is often undesirable. In particular can the high temperatures used for the Harming polyurethane. This damage can only counteracted by complex measures and only partially become. Monofilaments made of polypropylene terephthalate are e.g. known from EP-A-0 520 162 and JP-A-0 812 052. The object of the invention is therefore a monofilament for textile To create materials of the type mentioned, the extrudable in a simple manner and at lower temperatures and can be fixed later.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß das Kunststoffmaterial als Hauptbestandteil Polytrimethylenterephtalat (PTMT) aufweist, das einen Anteil Polyurethan von bis zu 45 Gew.-% aufweist, und das zu wenigstens 95 Gew.-% aus der Kombination von polytrimethylenterephthalat und Polyurethan besteht. Dadurch, daß erfindungsgemäß Polytrimethylenterephtalat (PTMT) an Stelle von den bisher verwendeten Polyethylenterephtalat-Materialien eingesetzt wird, kann in der gewünschten Weise das Extrudieren und das Fixieren der Monofilamente bei niedrigeren Temperaturen stattfinden. Hierdurch lassen sich insbesondere auch die Herstellungs- und Behandlungskosten deutlich senken. Im übrigen hat sich gezeigt, daß die Eigenschaften von Monofilamenten auf PTMA-Basis im Vergleich zu Monofilamenten auf PET-Basis stärker in Richtung der Eigenschaften von Polyamid gehen, was in bestimmten Fällen auch erwünscht sein kann. Gemäß einer bevorzugten Ausführungsform weist das Kunststoffmaterial zur Erhöhung der Abriebsfestigkeit insbesondere elastomeres Polyurethan (PU) auf, und zwar bis zu einem Anteil von 45 Gew.-%. In diesem Fall hat die erfindungsgemäße Verwendung von PTMT-Haterialen den weiteren Vorteil, daß die bei der Herstellung und Behandlung auftretenden Temperaturen so niedrig sind, daß sie das Polyurethan nicht schädigen und insofern die im Stand der Technik vorgesehen Schutzmaßnahmen entfallen können, was ebenfalls zur Kostensenkung beiträgt.This object is achieved in that the Plastic material as the main component polytrimethylene terephthalate (PTMT), which has a polyurethane content of up to 45% by weight has, and at least 95 wt .-% from the Combination of polytrimethylene terephthalate and Polyurethane is made. The fact that according to the invention polytrimethylene terephthalate (PTMT) instead of the previously used Polyethylene terephthalate materials can be used in the desired way of extruding and fixing the monofilaments take place at lower temperatures. Hereby especially the manufacturing and treatment costs significantly lower. It has also been shown that the properties of PTMA-based monofilaments in Compared to monofilaments based on PET more strongly in the direction the properties of polyamide go what in certain cases can also be desired. According to a preferred Embodiment has the plastic material to increase the Abrasion resistance, especially elastomeric polyurethane (PU) up to a proportion of 45 wt .-%. In this Case has the use of PTMT materials according to the invention the further advantage that the in the manufacture and treatment occurring temperatures are so low that they do not damage the polyurethane and, in so far, the state of the art Technology provided protective measures can be omitted, which also contributes to cost reduction.

In Ausbildung der Erfindung ist vorgesehen, daß das Kunststoffmaterial in an sich bekannter Weise einen Hydrolyse-Stabilisator enthält, und zwar vorzugsweise bis zu einem Anteil von 5 Gew.-%. Die schmelzextrudierten Monofilamente gemäß der Erfindung können eine beliebige Querschnittsform haben, d.h. sie können beispielsweise rechteckig, kleeblattförmig, hundknochenförmig, sternförmig, rund, oval oder dergleichen ausgebildet sein und insbesondere auch einen Hohlquerschnitt aufweisen. Die Querschittsfläche der Monofilamente liegt vorzugsweise zwischen 0,02 mm2 und 3,5 mm2, was bei einem runden Querschnitt einem Durchmesser von 0,08 bis 1 mm entspricht.In an embodiment of the invention it is provided that the plastic material contains a hydrolysis stabilizer in a manner known per se, preferably up to a proportion of 5% by weight. The melt-extruded monofilaments according to the invention can have any cross-sectional shape, ie they can be, for example, rectangular, cloverleaf-shaped, dog-bone-shaped, star-shaped, round, oval or the like and in particular also have a hollow cross-section. The cross-sectional area of the monofilaments is preferably between 0.02 mm 2 and 3.5 mm 2 , which corresponds to a diameter of 0.08 to 1 mm for a round cross section.

Das PTMT-Material kann beispielsweise durch Kondensation von Terephthalsäure und 1,3-Propandiol hergestellt sein.The PTMT material can, for example, by condensation of Terephthalic acid and 1,3-propanediol.

PTMT-Haterialien sind zwar an sich bereits bekannt und auch schon zur Herstellung von Fasern eingesetzt worden. Die dabei erzielte spezifische Festigkeit war jedoch für den Einsatzbereich in festigkeitstragenden Strukturen wie technischen Geweben und Gewirken zu gering. Umso mehr mußte es überraschen, daß die erfindungsgemäßen Honofilamente auf PTMT-Basis eine für den Einsatz in solchen technischen Textilien und insbesondere Papiermaschinenbespannungen ausreichende Festigkeit aufweisen.PTMT materials are already known per se and also have already been used for the production of fibers. The one there However, the specific strength achieved was for the area of application in strength-bearing structures such as technical fabrics and knitted too little. It was all the more surprising, that the honofilaments of the invention based on PTMT for use in such technical textiles and in particular Paper machine clothing has sufficient strength.

Des weiteren konnten mit den erfindungsgemäß schmelzextrudierten Monofilamenten auch wesentlich höhere Verstreckungsgrade erreicht werden, als dies in der Literatur für Fasern auf PTMT-Basis angegeben ist. In Versuchen wurden mit den erfindungsgemäßen Monofilamenten Verstreckungsgrade von zu 1,0 : 4,5 erreicht, demgegenüber sind die für PTMT-Fasern erreichbaren Verstreckungsgrade in der Literatur lediglich mit 1,0 : 2,4 angegeben.Furthermore, melt-extruded according to the invention could Monofilaments also significantly higher degrees of stretching be achieved than in the literature for fibers PTMT base is specified. In experiments with the invention Monofilament degrees of stretch of too 1.0: 4.5 achieved, in contrast, the achievable for PTMT fibers Degree of stretching in the literature only with 1.0: 2.4.
