Description

Die Erfindung betrifft ein Verfahren zur Herstellung von vakuolenfreien, wärmegeschützten, runden Monofilamenten aus Polyamid für technische Gewebe.The invention relates to a method for producing vacuole-free, heat-protected, round monofilaments made of polyamide for technical fabrics.

Die Herstellung von Monofilamenten zur Verstärkung in Gummiartikeln, insbesondere für Reifen, ist bekannt. Aus der US-A-5,262,099 ist ein Verfahren zur Herstellung von Monofilamenten durch Extrudieren in Wasser bekannt, deren Durchmesser oval gestaltet sind. Obwohl Titer bis 12000 Denier (etwa 13000 dtex) entsprechend etwa 1.3 mm Durchmesser genannt werden, sind in den Beispielen höchstens 6000 Denier (etwa 6700 dtex) entsprechend etwa 0.85 mm Durchmesser ausgeführt. Bei der Herstellung von Monofilen mit einem Durchmesser von > 0.8 mm treten beim Extrudieren in Wasser bereits Abkühlprobleme auf, die sich durch Bildung von Vakuolen im fertigen Monofilament manifestieren. Diese Monofilamente sind zur Herstellung von Geweben für technische Zwecke ungeeignet, da häufig Fadenbrüche auftreten und die Garneigenschaften nicht konstant sind. The production of monofilaments for reinforcement in Rubber articles, in particular for tires, are known. Out US-A-5,262,099 is a process for the manufacture of Monofilaments known by extrusion in water, the Diameters are oval. Although titers up to 12000 Denier (about 13000 dtex) corresponding to about 1.3 mm Diameters are mentioned in the examples a maximum of 6000 denier (about 6700 dtex) corresponding to about 0.85 mm diameter. In the manufacture of Monofilaments with a diameter of> 0.8 mm occur Extrude cooling problems in water that already through the formation of vacuoles in the finished monofilament manifest. These monofilaments are for manufacturing of fabrics unsuitable for technical purposes, since often Thread breaks occur and the yarn properties do not are constant.

Aus der EP-A-0 230 228 ist auch bekannt, Drähte (Monofile) mit rundem Durchmesser aus einer Mischung von Polyamid 66 und Polyamid 6 für Spiralsiebe für die Papierindustrie herzustellen. Allerdings wurde festgestellt, dass der Gesamtgehalt an PA 6, 15 Gew.-% nicht übersteigen darf. Nach dem bekannten Verfahren werden Polyamiddrähte mit einem Durchmesser von 0.3 bis 0.7 mm hergestellt. Bei diesen bekannten Durchmessern treten noch keine Vakuolen im Monofilament auf.From EP-A-0 230 228 wires are also known (Monofilament) with a round diameter from a mixture of Polyamide 66 and polyamide 6 for spiral screens for the Paper industry. However found that the total content of PA 6, 15 wt .-% must not exceed. According to the known method are polyamide wires with a diameter of 0.3 to 0.7 mm manufactured. With these known diameters there are no vacuoles in the monofilament.

Es besteht schon lange das Bedürfnis, gröbere Monofilamente für Reifenkorde zu verwenden. Unter groben Monofilamenten sind solche mit einem Titer von mehr als 8000 dtex, entsprechend einem Drahtdurchmesser von mehr als etwa 0.9 mm zu verstehen. Die Verwendung von PA 6 allein als auch Copolyamide davon, führten nicht zu dem gewünschten Erfolg. PA 6 allein ist wegen des niedrigen Schmelzpunktes (ca. 218°C) bei den vorgesehenen Vulkanisationstemperaturen für schwere Reifen, wie beispielweise LKW-Reifen nicht einsetzbar.There has long been a need to coarser Use monofilaments for tire cords. Under rough Monofilaments are those with a titer of more than 8000 dtex, corresponding to a wire diameter of more to be understood as about 0.9 mm. The use of PA 6 alone as well as copolyamides thereof did not lead to that desired success. PA 6 alone is because of the low Melting point (approx. 218 ° C) at the intended Vulcanization temperatures for heavy tires, such as for example truck tires cannot be used.

Aufgabe der Erfindung ist es, ein Verfahren zur Verfügung zu stellen, mit welchem vakuolenfreie grobe Monofilamente aus leichtem synthetischen Material für den Einsatz in Geweben für Karkassen oder andere textile Einlagematerialien in schweren Reifen herstellbar sind.The object of the invention is to provide a method to ask with which vacuole coarse monofilaments made of light synthetic material for use in fabrics for Carcasses or other textile insert materials in heavy tires can be produced.

Eine weitere Aufgabe ist es, solche Monofilamente auch wirtschaftlich herzustellen. Another job is to make such monofilaments too economical to manufacture.

Die Aufgabe wird erfindungsgemäss durch ein Verfahren zur Herstellung der Monofilamente gelöst, wobei die Monofilamente aus einer Mischung aus 75 - 85 Gew.-% PA 66 und 15 bis 25 Gew.-% PA 6 bestehen und die Mischung unmittelbar vor dem Extrudieren vermischt, versponnen und direkt in einer Flüssigkeit abgekühlt wird.According to the invention, the object is achieved by solved a process for producing the monofilaments, where the monofilaments are made from a mixture of 75-85% by weight of PA 66 and 15 up to 25 wt .-% PA 6 and the mixture immediately before extruding mixed, spun and directly in a liquid is cooled.

Es hat sich in überraschender Weise gezeigt, dass nicht ein Copolyamid, sondern lediglich eine Mischung unterschiedlicher Polyamide zu einem vakuolenfreien. groben Monofilament führt und damit ein möglichst hoher Schmelzpunkt erreicht wird. Dabei ist das Verhältnis der Mischung von entscheidender Bedeutung. Bei 15 Gew.-% PA 6 und weniger treten bereits Vakuolen auf, welche die Reissfestigkeit eines daraus hergestellten Gewebes negativ beeinflussen. Bei einem Zusatz von mehr als 25 Gew.-% an PA 6 wird der Schmelzpunkt der Mischung so stark erniedrigt, dass die gewünschten Fadeneigenschaften und Schmelzpunkthöhen nicht mehr erreicht werden.Surprisingly, it has been shown that not a copolyamide, just a mixture different polyamides to a vacuole-free. leads coarse monofilament and thus the highest possible Melting point is reached. The ratio is the Mixture vital. At 15% by weight of PA 6 and fewer vacuoles already occur, which the Tear strength of a fabric made from it influence negatively. When adding more than 25 % By weight of PA 6 becomes the melting point of the mixture greatly lowered that the desired thread properties and melting point heights can no longer be reached.

Es ist zweckmässig das Verspinnen mit einer Spritzgeschwindigkeit von > 10 m/min, in ein Kühlbad mit einer Temperatur von < 60 °C durchzuführen. Bei einer Spritzgeschwindigkeit von weniger als 10 m/min können Fadenabrisse auftreten; bei mehr als 20 m/min ist die Durchführung des nachfolgenden Abkühl-/Streckprozesses nicht mehr gewährleistet.It is useful to spin with a Spraying speed of> 10 m / min, in a cooling bath with a temperature of <60 ° C. At a Spray speed of less than 10 m / min can Thread breaks occur; at more than 20 m / min Execution of the subsequent cooling / stretching process no longer guaranteed.

Es ist zweckmässig, dem PA 66 wenigstens 30 ppm, bevorzugt mehr als 60 ppm Cu, aber nicht mehr als 120 ppm zu zugeben. Die Zugabe des gesamten Wärmeschutzes, eingebettet im PA-66-Polymergranulat, hat den Vorteil der guten Enddurchmischung im Monofilament ohne nennenswerte Degradation des Polymers und das Kupfer wird durch die Einbettung im Polymer daran gehindert, beispielsweise am Extruderrohr, auszusintern. Das Kupfer wird in Form eines Kupfersalzes eingesetzt. Als Kupfersalz kommt vorzugsweise ein Halogenid wie Kupfer-II-Chlorid, Bromid oder Jodid in Frage.It is advisable to add at least 30 ppm to the PA 66, preferably more than 60 ppm Cu, but not more than 120 ppm to admit. The addition of all the heat protection, embedded in the PA-66 polymer granulate has the advantage of good final mixing in the monofilament without any noteworthy Degradation of the polymer and the copper is caused by the Embedding in the polymer prevented, for example on Extruder tube to be sintered. The copper is in the form of a Copper salt used. When copper salt comes preferably a halide such as copper (II) chloride, bromide or iodide in question.

Es ist vorteilhaft PA 66 und das PA 6 gemischt in Granulatform einem Extruder, insbesondere einem Entgasungsextruder zu zugeben. Dabei spielt die Granulatdicke für die Mischung eine wichtige Rolle. Sie hat einen wesentlichen Einfluss auf die Austreibung der Feuchte im Extruder.It is advantageous to mix PA 66 and PA 6 in Granulate form an extruder, especially one Add degassing extruder. The plays Granule thickness plays an important role in the mix. she has a significant impact on the expulsion of the Moisture in the extruder.

Als zweckmässig hat sich eine Granulatmischung mit einem Korngewicht von 10 bis 200 mg, vorzugsweise 10 bis 100 mg, insbesondere 15 bis 80 mg erwiesen. Ein Korngewicht von weniger als 10 mg führt bei den gebräuchlichen Einzugsschnecken zu Einzugsstörungen; eine Korngewicht von mehr als 100 mg führt zu einer schlechten Durchmischung. Hierbei ist darauf zu achten, dass die Korngrösse der Granulate für PA 66 und PA 6 etwa gleich ist.A mixture of granules with a Grain weight of 10 to 200 mg, preferably 10 to 100 mg, especially 15 to 80 mg. A grain weight of less than 10 mg leads to the most common Feed augers for feeding problems; a grain weight of more than 100 mg leads to a bad one Mixing. It is important to ensure that the Grain size of the granules for PA 66 and PA 6 approximately the same is.

Ein Monofilament für technische Gewebe, mit einem runden Querschnitt von 0.8 bis 1.5 mm bevorzugt 0.9 bis 1.2 mm und einem Schmelzpunktsbereich von 235-260°C vorzugsweise 245°C-260°C, insbesondere 255 - 260°C ist besonders zur Herstellung der Gewebe zum Einsatz für Karkassen und Breaker in Reifen geeignet. Ein runder Querschnitt hat den Vorteil gegenüber einem nicht rundem Querschnitt, dass sich das Monofilament beim Verarbeiten zu kalandrierten Geweben nicht verdreht. Eine Monofildicke von < 0.8 mm hat den Nachteile einer ungenügenden Reissfestigkeit und Stabilität; eine Monofildicke von > 1.5 kann nicht mehr hergestellt werden.A monofilament for technical fabrics, with a round one Cross section from 0.8 to 1.5 mm, preferably 0.9 to 1.2 mm and a melting point range of 235-260 ° C is preferred 245 ° C-260 ° C, especially 255 - 260 ° C is especially for Manufacture of fabrics for use in carcasses and Suitable for breakers in tires. Has a round cross section the advantage over a non-round cross-section, that the monofilament is processing calendered fabrics not twisted. A monofilament thickness of <0.8 mm has the disadvantages of an insufficient Tear resistance and stability; a monofilament thickness of> 1.5 can no longer be manufactured.
