Abstract

There is described a fibre, in particular a monofilament for paper machine wire-cloths, that comprises polyphenylene sulphide and has been drawn. The polyphenylene sulphide is a mixture of 60-90 per cent by weight of a high molecular weight polyphenylene sulphide having a melt flow index of not more than 100 and 10-40 per cent by weight of a low molecular weight polyphenylene sulphide having a melt flow index of at least 120. This fibre has approximately the longitudinal strength of a fibre that consists exclusively of the higher molecular weight polyphenylene sulphide, while the relative knot strength is appreciably higher than that of the higher molecular weight polyphenylene sulphide.

Description

Die Erfindung betrifft eine Faser, insbesondere ein Monofil für Papiermaschinensiebe, die bzw. das aus Polyphenylen­sulfid besteht und verstreckt ist.The invention relates to a fiber, in particular a monofilament for paper machine screens, which consists of polyphenylene sulfide and is stretched.

Ein derartiges Monofil ist aus den EP-Patentanmeldungen 161 579, 221 691 und 292 186 bekannt. Übereinstimmend wird in diesen Patenten betont, daß ausschließlich aus Poly­phenylensulfid bestehende Monofile sehr spröde und daher für viele Anwendungszwecke, so zum Beispiel als Monofile für Papiermaschinensiebe, ungeeignet sind. In diesen Patent­anmeldungen werden daher Mischungen aus Polyphenylensulfid und anderen Polymeren, wie zum Beispiel Polyamiden oder Polyolefinen, beschrieben.Such a monofilament is known from EP patent applications 161 579, 221 691 and 292 186. It is emphasized in these patents that monofilaments consisting exclusively of polyphenylene sulfide are very brittle and are therefore unsuitable for many applications, for example as monofilaments for paper machine screens. In these patent applications, mixtures of polyphenylene sulfide and other polymers, such as polyamides or polyolefins, are therefore described.

Der Erfindung liegt die Aufgabe zugrunde, eine Faser, insbe­sondere ein Monofil für Papiermaschinensiebe zur Verfügung zu stellen, die bzw. das ausschließlich aus Polyphenylen­sulfid besteht und dennoch eine hohe Längsfestigkeit und Knoten-Höchstzugkraft besitzt.The invention has for its object to provide a fiber, in particular a monofilament for paper machine screens, which or which consists exclusively of polyphenylene sulfide and yet has a high longitudinal strength and maximum knot tensile strength.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Polyphenylensulfid ein Gemisch aus 60 bis 90 Gewichtsprozent eines hochmolekularen Polyphenylensulfids mit einem Melt-­Flow-Index-Wert von höchstens 100 und 10 - 40 Gewichts­prozent eines niedermolekularen Polyphenylensulfids mit einem Melt-Flow-Index-Wert von mindestens 120 ist.This object is achieved in that the polyphenylene sulfide is a mixture of 60 to 90 percent by weight of a high molecular weight polyphenylene sulfide with a melt flow index value of at most 100 and 10 to 40 percent by weight of a low molecular weight polyphenylene sulfide with a melt flow index value of is at least 120.

Hierbei ist der Melt-Flow-Index in g/10 min. gemessen, und zwar mit einem Zwick-Rheometer bei 315°C und einer Stempel­belastung von 5 kg, einem Düsenbohrungsdurchmesser von 2,095mm und einer Düsenbohrungslänge von 8mm.The melt flow index is in g / 10 min. measured, namely with a Zwick rheometer at 315 ° C and a stamp load of 5 kg, a nozzle bore diameter of 2.095mm and a nozzle bore length of 8mm.

Von der Anmelderin wurde festgestellt, daß hochmolekulares, (also hochviskoses) Polyphenylensulfid zu Fasern großer Längsfestigkeit, jedoch geringer Knoten-Höchstzugkraft (Querfestigkeit) führt, wogegen bei Fasern aus niedermolekularem (niederviskosem) Polyphenylensulfid die Längsfestigkeit gering, die Knoten-Höchstzugkraft dagegen relativ groß ist.The applicant has determined that high molecular weight (i.e. highly viscous) polyphenylene sulfide leads to fibers with high longitudinal strength but low maximum knot tensile strength (transverse strength), whereas fibers made from low molecular weight (low viscosity) polyphenylene sulfide have low longitudinal strength, whereas the maximum knot tensile strength is relatively large .

Aus der EP 237 006 A2 ist bereits bekannt, daß eine Mischung aus zwei Polyphenylensulfiden unterschiedlicher Molekulargewichte, also eine bimodale Molekulargewichts­verteilung, zu einer Erhöhung der Kristallisationstem­peratur und zu einer Verbesserung der Steifigkeit, der Biegefestigkeit und der Kugeldruckfestigkeit gegenüber einem Polymer gleicher Schmelzviskosität führen soll. Die EP 237 006 A2 befaßt sich in erster Linie mit Kunststoff für dreidimensional isotrope Spritzgußteile. Wenn auch in dieser Druckschrift in einer größeren Aufzählung verschiedener Anwendungsbeispiele beiläufig Garne erwähnt werden, so schienen jedoch derartige bimodale Polyphenylensulfidgemische für uniaxial hochbelastbare Fasern (wie etwa Monofile in Papiermaschinensieben) ungeeignet, da durch das Zumischen der niederviskosen Komponente ein Absinken der Längsfestigkeit der Fasern unvermeidlich schien.From EP 237 006 A2 it is already known that a mixture of two polyphenylene sulfides of different molecular weights, i.e. a bimodal molecular weight distribution, should lead to an increase in the crystallization temperature and to an improvement in the rigidity, the flexural strength and the ball compressive strength compared to a polymer of the same melt viscosity. EP 237 006 A2 is primarily concerned with plastic for three-dimensionally isotropic injection molded parts. Even though yarns are mentioned in this publication in a larger list of different application examples, such bimodal polyphenylene sulfide mixtures seemed to be unsuitable for fibers that can withstand high uniaxial loads (such as monofilaments in paper machine screens), since a decrease in the longitudinal strength of the fibers seemed inevitable due to the admixture of the low-viscosity component .

Überraschenderweise hat sich nun gezeigt, daß die Festigkeit einer orientierend verstreckten Faser aus einer Polyphenylensulfid-Mischung mit der oben angegebenen bimodalen Molekulargewichtsverteilung annähernd die Festigkeit einer Faser aus dem hochmolekularen (hochviskosen) Polyphenylensulfid erreicht. Offensichtlich wird aufgrund der Verstreckung der Faser die feinheitsbezogene Höchstzugkraft der Faser durch das Zugeben von niedermolekularem Polyphenylen­sulfid entgegen aller Erwartung kaum beeinträchtigt. Gieich­zeitig hat jedoch das Zugeben des niedermolekularen Polyphenylensulfids die vorteilhafte Wirkung, daß die relative Knoten-Höchstzugkraft sehr stark zunimmt.Surprisingly, it has now been shown that the strength of an oriented oriented fiber made of a polyphenylene sulfide mixture with the bimodal molecular weight distribution given above almost reaches the strength of a fiber made of the high molecular weight (high viscosity) polyphenylene sulfide. Obviously, due to the stretching of the fiber, the fineness-related maximum tensile strength of the Contrary to all expectations, fiber hardly adversely affected by the addition of low molecular weight polyphenylene sulfide. At the same time, however, the addition of the low molecular weight polyphenylene sulfide has the advantageous effect that the relative maximum knot tensile strength increases very strongly.

Die erfindungsgemäß ausgebildete Faser besteht somit ausschließlich aus Polyphenylensulfid, d.h. sie enthält kein anderes faserbildendes Polymermaterial, so daß die vorteilhaften Eigenschaften dieses Polymers voll erhalten bleiben. Gegebenenfalls können aber Zusätze von Antioxidantien, Pigmenten, Farbstoffen oder ähnlichen, für die Herstellung synthetischer Fasern gebräuchlichen Zuschlagstoffen verwendet werden.The fiber designed according to the invention thus consists exclusively of polyphenylene sulfide, i.e. it contains no other fiber-forming polymer material, so that the advantageous properties of this polymer are fully retained. Optionally, however, additives of antioxidants, pigments, dyes or similar additives used for the production of synthetic fibers can be used.

Vorzugsweise beträgt das Verstreckverhältnis 3:1 bis 5:1, das heißt, die Faser sollte weitgehend maximal verstreckt werden. Die Höchstzugkraftdehnung liegt dann meist zwischen 30 und 40%.The draw ratio is preferably 3: 1 to 5: 1, that is to say that the fiber should largely be drawn to a maximum. The maximum tensile strength stretch is then usually between 30 and 40%.

Die erfindungsgemäß ausgebildete Faser hat zweckmäßigerweise eine feinheitsbezogene Höchstzugkraft über 25 cN/tex und eine Knoten-Höchstzugkraft (DIN 53 842, Teil 1) von mindestens 60% dieses Wertes. Bei der Faser kann es sich sowohl um ein Multifilament wie auch um eine Spinnfaser handeln. Besonders vorteilhaft ist jedoch der Einsatz der Erfindung bei Monofilen, insbesondere für Papiermaschinensiebe. Der bevorzugte Durchmesserbereich der Monofile liegt bei 0,2 bis 1 mm, wenngleich die Erfindung auch bei Monofilen außerhalb dieses Durchmesserbereiches (mit einer unteren und oberen Durchmessergrenze von ungefähr 20 µm und 3 mm eingesetzt werden kann.The fiber designed according to the invention expediently has a fineness-related maximum tensile strength above 25 cN / tex and a knot maximum tensile strength (DIN 53 842, Part 1) of at least 60% of this value. The fiber can be both a multifilament and a staple fiber. However, the use of the invention is particularly advantageous in the case of monofilaments, in particular for paper machine screens. The preferred diameter range of the monofilaments is 0.2 to 1 mm, although the invention can also be used for monofilaments outside this diameter range (with a lower and upper diameter limit of approximately 20 μm and 3 mm.
