Description

Die Erfindung betrifft ein Verfahren zum Verbinden von Geweben, wobei die Verbindungsstelle hochtemperaturbeständig und nicht dicker als die doppelte Gewebedicke ist. 2>The invention relates to a method for joining fabrics, wherein the joining point is high-temperature resistant and not thicker than twice Tissue thickness is. 2>

Es ist bekannt, Gewebebahnen mittels Nähen zu verbinden. Diese Verbindungsart hat für zahlreiche Anwendungsfälle den Nachteil, daß die Verbindungsstelle ein Mehrfaches der Dicke des Gewebes aufweist. Hierdurch entstehen beim Aufwickeln der Gewebebahn «1 Wülste, die sich durch mehrere Lagen durchdrücken.It is known to connect fabric webs by means of sewing. This type of connection has for numerous Applications have the disadvantage that the connection point has a multiple of the thickness of the fabric. As a result, when the web of fabric is wound up, bulges arise which push through several layers.

Zur Vermeidung dieser Wulstbildung werden nach einem anderen Verfahren Gewebeenden mittels einer Folie im Hochfrequenzverfahren verschweißt. Bei diesem Verfahren ist es erforderlich, daß die Folie einen r> möglichst hohen dielektrischen Verlustfaktor und einen möglichst niedrigen Erweichungspunkt besitzt, so daß sie beim Schweißen schmilzt. Der Nachteil dieser Methode besteht in der sehr aufwendigen Schweißapparatur und außerdem ist die Schweißnaht nicht genügend temperaturbeständig, so daß bei einer anschließenden Beschichtung mit Kunststoff die Gefahr besteht, daß infolge des niedrigen Erweichungspunktes der Folie die Verbindungsstelle reißt. In order to avoid this bulge formation, fabric ends are welded using a film using a high-frequency process. In this process it is necessary that the film has a dielectric loss factor which is as high as possible and a softening point which is as low as possible so that it melts during welding. The disadvantage of this method is the very expensive welding equipment and, moreover, the weld seam is not sufficiently temperature-resistant, so that when subsequently coated with plastic there is the risk that the connection point will tear as a result of the low softening point of the film.

Überraschenderweise wurde nun gefunden, daß man 4 > diese Nachteile beheben kann, wenn man nach dem erfindungsgemäßen Verfahren arbeitet. Es betrifft ein Verfahren zum Verbinden von Gewebeteilen, das dadurch gekennzeichnet ist, daß man zwischen die zu verbindenden Gewebeenden eine hochtemperaturbe- ">o ständige Folie einbringt, nachdem man die Gewebeenden mit einem leicht flüchtigen Lösungsmittel für die Folie getränkt hat und die Gewebeenden durch Pressen verbindet. Surprisingly, it has now been found that these disadvantages can be eliminated by working according to the process according to the invention. It relates to a procedural r s for connecting tissue parts, which is characterized by introducing between the tissue to be joined ends of a high-temperature-"> o continuous film, after having impregnated the fabric ends with a volatile solvent for the film and the fabric ends connects by pressing.

Hochtemperaturbeständige Folien mit einer Dicke r> zwischen 20 und 100 μ eignen sich für das Verfahren. Besonders geeignet sind Polyhydantoinfolien, die man gemäß der Patentschrift 12 30 568 herstellt. High temperature resistant foils with a thickness r> between 20 and 100 μ are suitable for the process. Polyhydantoin films which are produced according to patent specification 12 30 568 are particularly suitable.

Als Lösungsmittel eignen sich leicht flüchtige Lösungsmittel, z. B. Methylenchlorid. wiEasily volatile solvents are suitable as solvents, e.g. B. methylene chloride. wi

Der beim Pressen angewendete Druck liegt zwischen 5 — 55 kp/cm2. Üblicherweise wird das Pressen bei Zimmertemperatur durchgeführt. Die Preßtemperatur kann ;ibcr bis zum Siedepunkt des Lösungsmittels erhohl werden, wodurch die Verbindungsfestigkeit noch tu gesteigert und die Preßdauer, die /wischen I Sekunde um.I I Minute liegt /11 den kürzeren /eilen verschoben w ii'il.The pressure applied during pressing is between 5 - 55 kp / cm 2 . The pressing is usually carried out at room temperature. The pressing temperature can be raised to the boiling point of the solvent, which increases the strength of the connection and the pressing time, which is between 1 second and 2 minutes, is shifted to the shorter one.

Nach dem erfindungsgemäßen Verfahren können Gewebe natürlicher und synthetischer Herkunft innerhalb kurzer Zeit sehr fest und temperaturbeständig verbunden werden, wie zum Beispiel Baumwollgewebe, Gewebe aus Polyester, Polyamiden, Polyurethanen und Glas, ohne daß bei einer anschließenden Beschichtung mit Kunststoff eine Trennung der Gewebebahnen zu beobachten wäre.According to the method according to the invention, fabrics of natural and synthetic origin can become very strong and temperature-resistant within a short time such as cotton fabrics, fabrics made of polyester, polyamides, polyurethanes and Glass, without a separation of the fabric webs during a subsequent coating with plastic would be watching.

Die Klebestelle ist temperaturbeständig bis 26O0C und wird von einer Schmelze aus weichgemachtem PVC nicht geschädigt.Between the overlapping web ends of a cotton fabric wetted with methylene chloride, a film strip made of non-oriented amorphous polycarbonate film based on isatin bisphenol with a thickness of approx. 40 μ is inserted. 20 kp / cm 2 , the web ends are moved approx. 10 seconds onto one another. The strength of the joint is higher than the strength of the fabric, even when comparing the strengths at a higher temperature. A numerical value for the strength of the connection point ι »cannot therefore be determined. The splice is temperature resistant not damaged to 26O 0 C and is of a melt of plasticized PVC.
