Abstract

A sheet-like polyurethane foam with high slidability or abrasion resistance and extensibility is specified, which can be laminated with other sheet-like structures of textile fibres, natural leather or synthetic leather and is then used for seat coverings. The foam is provided on one side with a plastic strip-grid coating which has an essentially cross-shaped arrangement and has received the desired slidability by smoothing. The application of the strip-grid coating may be carried out, for example, by screen printing. By virtue of the rod-shaped coating, the extensibility of the sheet-like polyurethane foam is completely retained.

Description

Die Erfindung betrifft einen flächigen Polyurethan-Schaumstoff mit hoher Gleitfähigkeit und insbesondere einen flächigen Polyurethan-Schaumstoff, der mit anderen Flächengebilden aus beispielsweise Textilfasern, Natur- oder Kunstleder kaschiert wird und dann für Sitzbezüge oder auch Schonbezüge, wie sie insbesondere in Autos verwendet werden, geeignet ist. Die Erfindung betrifft auch ein Verfahren zur Herstellung solcher flächiger Polyurethan-Schaumstoffe und deren Verwendung zum Kaschieren mit anderen Flächengebilden, beispielsweise für Sitzbezüge, und insbesondere auch für Schonbezüge.The invention relates to a flat Polyurethane foam with high lubricity and in particular a flat polyurethane foam, the with other fabrics from for example Textile fibers, natural or synthetic leather is laminated and then for seat covers or protective covers, like them are particularly suitable for use in cars. The The invention also relates to a method of manufacture such flat polyurethane foams and their Use for lamination with other fabrics, for example for seat covers, and especially for Slipcover.

Bei Sitzmöbeln wird auf einer Unterlage, die beispielsweise ein Polyurethan-Schaumstoff oder ein Federkern sein kann, ein Überzugsmaterial aus einem Textilmaterial oder Natur- oder Kunstleder aufgebracht. Bei Schonbezügen, wie sie insbesondere in Personenwagen für die Sitze verwendet werden, bestehen diese Schonbezüge aus einem der jeweiligen Sitzform angepaßten Textil- oder Natur- oder Kunstledermaterialien. Dabei wird dieses als Überzug dienende Überzugsmaterial - dies schließt nachfolgend ein Überzugsmaterial aus Textilfasern oder Natur- oder Kunstleder ein - mit einer dünnen Polyurethan-Schaumschicht kaschiert. Hierdurch wird ein zusätzlicher Polstereffekt bewirkt und dem Überzugsmaterial zusätzlich die erforderliche Weichheit und Fülle verliehen. Um den Kaschierverbund nähen und über den Sitzkern ziehen zu können, wurde der auf das Überzugsmaterial aufkaschierte Schaumstoff bisher mit einem elastischem Gewirke durch Flammkaschieren verbunden. Durch das Gewirke wird zwar die Gleitfähigkeit beim Nähen und Überziehen über den Sitzkern verbessert, gleichzeitig wird aber auch die Dehnfähigkeit des Schaumstoffes vermindert.In the case of seating furniture, a covering material made of a textile material or natural or synthetic leather is applied to a base, which can be, for example, a polyurethane foam or a spring core. In the case of protective covers, such as those used in particular in passenger cars for the seats, these protective covers consist of a textile or natural or synthetic leather material which is adapted to the respective seat shape. This covering material, which serves as a covering - which subsequently includes a covering material made of textile fibers or natural or synthetic leather - is laminated with a thin layer of polyurethane foam. This creates an additional cushioning effect and also gives the covering material the required softness and fullness. In order to be able to sew the lamination composite and pull it over the seat core, the foam laminated onto the covering material has previously been connected to an elastic knitted fabric by flame lamination. The knitted fabric improves the gliding ability when sewing and pulling over the seat core, but at the same time the stretchability of the foam is reduced.

Aufgabe der Erfindung ist es, einen flächigen Polyurethan-Schaumstoff mit hoher Gleitfähigkeit, guter Abrieffestigkeit und hoher Dehnfähigkeit, der zum Kaschieren mit anderen Flächengebilden aus Textilfasern, Natur- oder Kunstledern verwendet wird, zur Verfügung zu stellen. Verbunden mit dieser Aufgabe ist es auch, ein Verfahren zur Herstellung eines solchen flächigen Polyurethan-Schaumstoffs aufzuzeigen.The object of the invention is a flat Polyurethane foam with high lubricity, good Abrasion resistance and high elasticity, which for Lamination with other fabrics made of textile fibers, Natural or synthetic leather is used, too put. Linked to this task is also a Process for producing such a flat To show polyurethane foam.

Diese Aufgabe wird durch einen flächigen Polyurethan-Schaumstoff gemäß dem Patentanspruch 1 gelöst.This task is accomplished by a flat Polyurethane foam solved according to claim 1.

In der anliegenden Zeichnung bedeuten:In the attached drawing:

Fig. 1 ein nicht maßstabsgetreuer Schnitt durch einen erfindungsgemäßen Polyurethanschaumstoff, und Fig. 1 is a not to scale section through a polyurethane foam according to the invention, and

Fig. 2a und 2b zeigen ebenfalls nicht maßstabsgetreu die kreuzförmige Anordnung der Stäbchen-Rasterbeschichtung. FIGS. 2a and 2b also show not to scale, the cross-shaped arrangement of the rods raster coating.

(1) bedeutet dabei den flächigen Polyurethan-Schaumstoff und (2) die Stäbchen-Rasterbeschichtung. ( 1 ) means the flat polyurethane foam and ( 2 ) the rod grid coating.

Beim erfindungsgemäßen Polyurethan-Schaumstoff ist eine stäbchenförmige Rasterbeschichtung aus Kunststoff einseitig aufgetragen. Diese Stäbchen-Rasterbeschichtung wird mit einem Flächengewicht von 8 bis 35 g, vorzugsweise 10 bis 30 g und insbesondere 20 bis 25 g/m2 aufgebracht.In the polyurethane foam according to the invention, a rod-shaped grid coating made of plastic is applied on one side. This rod grid coating is applied with a basis weight of 8 to 35 g, preferably 10 to 30 g and in particular 20 to 25 g / m 2 .

Die Stäbchen-Rasterbeschichtung besteht aus einem Kunststoff. Geeignete Kunststoffe sind beispielsweise Polyvinylchlorid (PVC), Polyamid, Polyurethan, Polyester, Polyethylen, Polypropylen, Polyacrylat, Polystyrol oder auch Butadien/Styrol-Copolymere. Besonders bevorzugt sind PVC, Polyethylen, Polyurethan und Polyamid, wobei PVC wegen seiner Schwerbrennbarkeit und aus Kostengründen am meisten bevorzugt ist.The stick grid coating consists of one Plastic. Suitable plastics are, for example Polyvinyl chloride (PVC), polyamide, polyurethane, polyester, Polyethylene, polypropylene, polyacrylate, polystyrene or also butadiene / styrene copolymers. Are particularly preferred PVC, polyethylene, polyurethane and polyamide, with PVC because of its flammability and for cost reasons on is most preferred.

Die Kunststoffe können als solche in an sich üblicher Weise Stäbchen-rasterförmig auf den flächigen Polyurethan-Schaumstoff einseitig aufgebracht werden. Dies kann beispielsweise durch Siebdruck erfolgen. Dabei können die Kunststoffe als solche vorliegen, oder sie liegen zur Vereinfachung des Siebdruckens als Dispersionspasten vor. Um eine gute Gleitfähigkeit auf dem Sitzkern oder im Falle der Verwendung als Schonbezug auf dem bereits mit einem Sitzbezug versehenen Sitz zu erzielen, ist es erforderlich, daß die Stäbchen-Rasterbeschichtung eine ausreichende Glätte aufweist. Dies kann dadurch erreicht werden, daß man den einseitig mit einer Stäbchen-Rasterbeschichtung versehenen flächigen Polyurethan-Schaumstoff durch Walzen schickt, beispielsweise durch einen Preßkalander oder Glättkalander. Aber auch eine Plattenpresse ist geeignet. Beim Glätten erfolgt ein Anschmelzen der äußeren Oberfläche der Stäbchen-Rasterbeschichtung, wobei auch eine ganz schwache Verbindung der einzelnen Stäbchen-Raster miteinander erfolgen kann. Eingeschlossen in die Erfindung ist somit auch, daß die einzelnen Stäbchen nach der Glättung an ihren jeweiligen Berührungspunkten schwach verbunden sind, wobei aber vorzugsweise jedes Stäbchen für sich isoliert, also ohne Kontakt zu den anderen Stäbchen vorliegt.The plastics can be more common as such Wise chopsticks in a grid pattern on the flat surface Polyurethane foam can be applied on one side. This can be done, for example, by screen printing. You can the plastics are present as such or they are Simplification of screen printing as dispersion pastes. To ensure good sliding on the seat core or in the event the use as a protective cover on the already with a To achieve a seat cover provided, it is required that the rod grid coating a has sufficient smoothness. This can be achieved be that one-sided with a Chopsticks grid coating provided flat Sends polyurethane foam by rolling, for example by a press calender or Smoothing calender. But a plate press is also suitable. When smoothing, the outer one melts Surface of the stick grid coating, also  a very weak connection between the individual Chopsticks grid can be done together. Locked in in the invention is thus also that the individual Chopsticks after smoothing on their respective Points of contact are weakly connected, though preferably each stick isolated, that is without There is contact with the other chopsticks.

Handelt es sich bei den verwendeten Kunststoffen oder Kunststoffpasten um solche, die vernetzbar sind, dann muß die Glättung vor oder während des Vernetzens erfolgen, da nach der Vernetzung die Glättung erschwert oder unmöglich ist.Is it the plastic used or Plastic pastes around those that can be networked, then must the smoothing takes place before or during crosslinking, because smoothing becomes difficult or impossible after crosslinking is.

Werden die Kunststoffe in Form einer Paste aufgetragen, so kann man die Viskosität der Paste in geeigneter Weise durch Zugabe von Wasser oder Verdickungsmitteln oder gegebenenfalls auch durch die Mitverwendung von Füllstoffen einstellen. Wesentlich ist, daß ein sauberer Druck und eine gute Verankerung auf dem Polyurethan-Schaumstoffsubstrat erfolgt.If the plastics are applied in the form of a paste, so you can adjust the viscosity of the paste in a suitable manner by adding water or thickeners or if necessary also by using Adjust fillers. It is essential that a cleaner Pressure and a good anchorage on the Polyurethane foam substrate is made.

Die die Rasterbeschichtung bildenden, im wesentlichen kreuzförmig angeordneten Stäbchen haben im allgemeinen eine Breite von 0,4 bis 1,2 mm und vorzugsweise 0,8 bis 1 mm und eine Lange von 2 bis 3 mm. Durch die kreuzförmig angeordnete Stäbchen-Rasterbeschichtung ergeben sich unbeschichtete Zwischenräume in der Größenordnung von vorzugsweise 0,8 bis 1,2 mm2. Diese Werte können aber je nach der Art der Beschichtung, des Fließverhaltens des verwendeten Kunststoffes beim Aufdrucken und bei der Glättung über- oder auch unterschritten werden.The essentially cruciform rods forming the grid coating generally have a width of 0.4 to 1.2 mm and preferably 0.8 to 1 mm and a length of 2 to 3 mm. The cross-shaped rod grid coating results in uncoated spaces of the order of magnitude of preferably 0.8 to 1.2 mm 2 . However, depending on the type of coating, the flow behavior of the plastic used when printing and smoothing, these values can be exceeded or undershot.

Unter "im wesentlichen" kreuzförmig angeordnet wird im Sinne der vorliegenden Erfindung verstanden, daß die Stäbchen, die eine größere Länge als Breite haben, abwechselnd längs und breit aufgebracht sind, wobei die Stirnseite eines Stäbchens an der Mitte der Längsseite eines anderen Stäbchens anliegt, ohne diese Stäbchen zu berühren. Dadurch ergibt sich die Kreuzform. Die Kreuze müssen aber nicht voll symmetrisch sein.Under "essentially" is arranged in a cross shape Understood the present invention that the  Chopsticks that are longer than they are wide, alternately applied lengthways and wide, the Face of a stick at the middle of the long side of another chopstick without these chopsticks touch. This creates the cross shape. The crosses but do not have to be fully symmetrical.

Erfindungsgemäß werden erhebliche Vorteile gegenüber den herkömmlich mit einem elastischen Gewirke verbundenen Schaumstoffen erzielt. Die Dehnfähigkeit des Schaumstoffes bleibt vollständig erhalten. Die Stäbchen-Rasterbeschichtung aus Kunststoff ist auch preisgünstiger als die Verwendung von flammkaschierten elastischen Gewirken. Wegen der sehr guten Gleitfähigkeit treten nach dem Kaschieren mit einem Überzugsmaterial beim Sitzen weniger oder keine Knickfalten auf. Ferner ist auch die Abriebfestigkeit verbessert.According to the invention there are considerable advantages over the conventionally associated with an elastic knitted fabric Foams achieved. The elasticity of the foam remains intact. The Chopsticks grid coating made of plastic is also cheaper than the use of flame-laminated elastic knitted fabrics. Because of the very good sliding properties join after covering with a covering material Have fewer or no creases. It is also improves abrasion resistance.
