Description

Verfahren zum Verbessern der Eigenschaften der Stoffhüllen von Spielbällen, insbesondere von Tennisbällen Die bisher zum Überziehen von Spielbällen, insbesondere Tennisbällen, dienenden Stoffhäillen in der Form von Geweben oder Filzen sind mit Rücksich auf eine gute Abriebfestigkeit ausschließlich aus Wolle gefertigt, wobei für einseitig gewebte Filze in der Unterseite auch die Verwendung einer Baumwoll- oder Zellwollkette in Verbindung mit Schußfäden aus Wolle vorgeschlagen wurde.Process for improving the properties of the fabric covers of game balls, especially of tennis balls The previously used for covering game balls, in particular Tennis balls, fabric shells in the form of fabrics or felts are provided with Backed up by a good abrasion resistance made exclusively from wool, whereby for felts woven on one side, a cotton cloth can also be used on the underside. or rayon warp in connection with weft threads of wool has been proposed.

Die auf der Oberseite dieser Stoffhüllen befindliche Wollflur nutzt sich. beim Spielen. verhäiltnismäßig rasch ab. Da die guten Spieleigenschaften der Bälle weitgehend durch die haarige Oberfläche der Stoffhülle bedingt sind, die den Luftwiderstand vergrößert, werden die Spieleigenschaften durch den bereits nach kurzer Zeit einttretenden. Verschleiß der Wollflur durch Schlag oder Aufprall wesenltlich verschlechtert, und die Bälle werden schnell unbrauchbar. The wool floor located on the top of these fabric covers uses themselves. while playing. relatively rapidly. Since the good playing characteristics of the Balls are largely due to the hairy surface of the fabric cover that the Increased air resistance, the playing characteristics are already after occurring in a short time. Significant wear and tear on the wool floor due to blows or impacts deteriorates, and the balls quickly become unusable.

Es hat sich nun gezeigt, daß die Abriebfestigkelt wesentlich verbessert werden kann, wenn die Stoff'hülle mit einem Kunststoff behandelt wird. It has now been shown that the abrasion resistance is significantly improved can be if the fabric cover is treated with a plastic.

Hierfür kommen in Betracht Lösungen, Emulsionen oder Suspensionen von Aminocapronsäurepolyamid, Polyhexamethylenadipinamid, Polyacrylnitril, Polyvinylchlorid, Polyäthylenterephthalat, Polyricinolsäure.Solutions, emulsions or suspensions can be used for this of aminocaproic acid polyamide, polyhexamethylene adipamide, polyacrylonitrile, polyvinyl chloride, Polyethylene terephthalate, polyricinoleic acid.

Diese Behandlung kann dabei in der Flocke, dem Garn, in dem fertigen Stoff oder der Ballhülle erfolgen. This treatment can take place in the flake, the yarn, in the finished product Fabric or the ball cover.

So läßt sich beispielsweise die Scheuerfestiglçeit eines mit 40/0 Aminocapronsäurepolyamid präparierten Wollfilzes um mehrere hundert Prozent verbesseren. For example, the abrasion resistance can be 40/0 Aminocaproic acid polyamide prepared wool felt by several hundred percent.

Bei einer Ausführungsform des Verfahrens wird dabei das Polyamid in Phenol, Methylcresol, Xylenol oder Cresolsäure gelöst und der Wollfilz bzw. das Wollgewebe mit der Lösung getränkt. Nach dem Verdampfen des Lösungsmittels hinterbleibt auf den Wollfasern ein dünner Polyamidfilm, der den Fasern die erwähnte Verbesserung derScheuerfestigkeit verleiht. In one embodiment of the method, the polyamide is used dissolved in phenol, methylcresol, xylenol or cresolic acid and the wool felt or the Wool fabric soaked with the solution. Remains after evaporation of the solvent A thin polyamide film on the wool fibers, which gives the fibers the aforementioned improvement which gives abrasion resistance.

Bei einer anderen Ausführnngsform wird beispielsweise Aminocapronsäurepolyamid, welches zur Erniedrigung des Schmelzpunktes 300/0 der monomeren Verbindung enthält, in fein zerstäubter Form dem Filz einverleibt und dieser dann. 15 Minuten auf I350 erhitzt. Bei dieser Temperatur schmilzt die Polyamidmischung auf die Wollfaser. In another embodiment, for example, aminocaproic acid polyamide, which contains 300/0 of the monomeric compound to lower the melting point, incorporated into the felt in a finely atomized form and then this. 15 minutes on I350 heated. At this temperature, the polyamide mixture melts onto the wool fiber.

Das Erhitzen kann beispielsweise bei der Herstellung von Tennisbällen mit der Aufvulikanisierung des Filzes auf den Gummirohling verbunden werden, so daß sich eine getrennte Behandlung erübrigt. In der gleichen Weise können die anderen vorerwähnten Kunststoffe dem Filz einverleibt werden.The heating can be used, for example, in the production of tennis balls be connected to the vulcanization of the felt on the rubber blank, so that separate treatment is unnecessary. In the same way the others can The aforementioned plastics are incorporated into the felt.

Nach der Behandlung kann der monomere Anteil durch eine HeiBwasserbehandilung aus dem Filz entfernt werden. In gleicher Weise wie die verschiedenen Kunststoffe können auch Mischpolymerisate, die zwei oder mehr der genannten Komponenten enthalten, verwendet werden. After the treatment, the monomeric part can be treated with hot water removed from the felt. In the same way as the various plastics copolymers containing two or more of the components mentioned can also be used, be used.

Um die Farbe des Polyamids der Wollfaser anm zugleichen, können den Polyamiden im Verlaufe ihrer Herstellung färbende Pigmente oder Farbstoffe einverleibt werden. To match the color of the polyamide to the wool fiber, you can use the Polyamides incorporated coloring pigments or dyes in the course of their production will.
