Verfahren zum Verbinden von GewebenMethod of joining fabrics

Die Erfindung betrifft ein Verfahren zum Verbinden von Geweben, wobei die Verbindungsstelle hochtemperaturbeständig ist.The invention relates to a method for connecting fabrics, the connecting point being resistant to high temperatures is.

Es ist bekannt, Gewebebahnen mittels Nähen zu verbinden. Diese Verbindungsart hat für zahlreiche Anwehdungsfälle den Nachteil, daß die Verbindungsstelle ein Mehrfaches der Dicke des Gewebes aufweist. Hierdurch entstehen beim Aufwickeln der Gewebebahn 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 application cases the disadvantage that the connection point has a multiple of the thickness of the fabric. This creates the Winding up of the fabric web, bulges that 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 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 oft nicht genügend temperaturbeständig, so daß bei einer anschließenden Beschichtung mit Kunststoff die Gefahr besteht, daß die Naht aufgeht.To avoid this bulging are after another Process The ends of the fabric are welded using a film using a high-frequency process. This procedure requires that the film has the highest possible dielectric loss factor and the lowest possible softening point possesses so that it melts when welding. The disadvantage of this method is the very complex welding equipment and in addition, the weld seam is often not sufficiently temperature-resistant, so that a subsequent coating with plastic there is a risk that the seam will open.

Es wurde nun gefunden, daß man 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 auf die aneinander stossenden Gewebeenden eine hochtemperaturbeständige Folie aufbringt, nachdem man die Gewebeenden mit einem leicht flüchtigen Lösungsmittel für die Folie getränkt hat, und die Gewebeenden durch anschließendes Pressen verbindet.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 method for joining pieces of tissue, which is characterized in that one on the abutting one another Tissue ends apply a high-temperature resistant film, after which the tissue ends with a slightly volatile Has soaked solvent for the film, and then joins the fabric ends by pressing.

Hochtemperaturbeständige Folien mit einer Dicke zwischen 20 und 100/U eignen sich für das Verfahren, Besonders geeignet sind Polyhydantoine, die man gemäß der Patentschrift 1,230,568 herstellt.High temperature resistant foils with a thickness between 20 and 100 / U are suitable for the process, particularly suitable are polyhydantoins, which are produced according to patent specification 1,230,568.

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

Der beim Pressen angewendete Druck liegt zwischen 5-55 kp/cm , Üblicherweise wird das Pressen bei Zimmertemperatur durchgeführt. Der Preßvorgang kann aber auch bei höherer Temperatur durchgeführt werden, wodurch die Verbindungsfestigkeit noch gesteigert und die Preßdauer, die zwischen 1 Sekunde und 1 Minute liegt, zu den kürzeren Zeiten verschoben wird.The pressure applied during pressing is between 5-55 kp / cm, The pressing is usually carried out at room temperature. The pressing process can also take place at a higher temperature carried out, whereby the connection strength is increased and the pressing time, which is between 1 second and 1 Minute is shifted to the shorter times.

Nach dem erfindungsgemäßen Verfahren können Gewebe natürlicher und synthetischer Herkunft innerhalb kurzer Zeit sehr fest und temperaturbeständig zu endlosen Gewebebahnen 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, tissues can be more natural and of synthetic origin, bonded very firmly and temperature-resistant to form endless webs of fabric within a short period of time such as cotton fabrics, fabrics made of polyester, polyamides, polyurethanes and glass, without any subsequent coating with plastic, a separation of the fabric webs would be observed.

Beispiel 1 ν/ Example 1 ν /

Zur stumpfen Verbindung von Bahnen eines Baumwollgewebes werden die mit Methylenchlorid getränkten Enden der zu verbindenden Bahmen auf Stoß zusammengefügt und ein ca. 2 cm breiter Folienstreifen aus 100/U dicker Polyhydantoinfolie ein- oder beidseitig auf die Bahnenden gelegt. Die Verbindungsstelle wird bei einer Preßtemperatur von ca. 40 C undFor the butt jointing of lengths of cotton fabric, the ends soaked with methylene chloride are to be connected Bames joined together and an approx. 2 cm wide film strip made of 100 / U thick polyhydantoin film placed on one or both sides of the web ends. The junction is at a pressing temperature of about 40 C and

einem spezifischen Preßdruck von ca. 20 kg/cm werden die Bahnenden ca. 10 Sekunden verpreßt. Die Festigkeit der Verbindungsstelle ist im allgemeinen größer als die Gewebefestigkeit. Ein Zahlenwert für die Festigkeit der Verbindungsstelle kann somit nicht bestimmt werden. Die Klebestelle ist temperaturbeständig bis 2600C und ist beständig gegen kochende 10 %±ge Natronlauge, kochendes ¥asserstoffperoxid und wird von einer Schmelze aus weichgemachtem PVC nicht geschädigt. The web ends are pressed for approx. 10 seconds using a specific pressure of approx. 20 kg / cm. The strength of the joint is generally greater than the strength of the tissue. A numerical value for the strength of the connection point cannot therefore be determined. The glue point is temperature- resistant up to 260 0 C and is resistant to boiling 10 % caustic soda, boiling hydrogen peroxide and is not damaged by a melt of plasticized PVC.

Die Festigkeit der Verbindungsstelle ist im allgemeinen größer als die Gewebefestigkeit, so daß keine Zahlenangaben gemacht werden können. Die Klebestelle ist temperaturbeständig bis 26o°C und ist beständig gegen kochende Io #ige Natronlauge, kochendes Wasserstoffperoxid und wird von einer Schmelze aus weichgemachtem PVC nicht geschädigt.On the web ends wetted with methylene chloride, butted of a glass silk fabric is a 20 mm wide film strip made of ten, u thick polyhydantoin film on both sides placed and the connection point at a temperature of about 4o ° C and a specific pressure of 2o kg / cm 5 to Io see. pressed. The strength of the joint is im generally greater than the fabric strength, so that no figures can be given. The splice is temperature resistant up to 26o ° C and is resistant to boiling sodium hydroxide solution, boiling hydrogen peroxide and is used by a melt made of plasticized PVC is not damaged.
