Description
Verfahren zur Herstellung von gefärbtem Kreppgummi Die Erfindung betrifft ein Verfahren zur Herstellung von gefärbtem Kreppgummi, insbesondere von Kreppgummisohlen, bei dem der Naturkrepp zwischen Brechwalzen vorgebrochen, in Kalander mit mehr als zwei Walzen in Platten ausgewalzt und schließlich dubliert wird. Bisher konnte Kreppgummi nicht gefärbt werden, weil die Fachwelt auf dem Standpunkt stand, daß Gummi sich nur dann gleichmäßig einfärben läßt, wenn er bis zur vollen Plastizität mastiziert wird und dann erst die Füllstoffe, Vulkanisationsmittel und Farbe zugegeben werden, weil sonst eine gute Homogenisierung und damit eine gleichmäßige Verteilung aller Stoffe, also auch der Farbe, nicht zu erreichen sei. Da man diese Art der Färbung bei Herstellung von Kreppgummi nicht anwenden konnte, ohne die Kreppstruktur des Gummis aufzugeben, so hielt man das Färben von Kreppgummi für unmöglich.Process for Making Dyed Crepe Gum The invention relates to a process for the production of colored crepe rubber, in particular crepe rubber soles, in which the natural crepe is pre-broken between crushing rollers, in calenders with more than two rollers rolled into plates and finally doubled. So far, crepe rubber could not be colored because the professional world took the view that rubber was can only be colored evenly if he masticated to full plasticity and only then the fillers, vulcanizing agents and paint are added, because otherwise a good homogenization and thus an even distribution of all Substances, including the color, cannot be achieved. Because you get this kind of coloring in the manufacture of crepe rubber could not be used without the crepe structure of the To give up gums, it was thought impossible to dye crepe gum.
Man hat bereits vorgeschlagen, die Färbung des Kreppgummis durch Färbung der Gummimilch zu erzielen. Die Versuche haben aber zu befriedigenden Ergebnissen noch nicht geführt. Es sind dabei hochwertige Farbstoffe erforderlich, die das Mehrfache der sonst bei der Gummifabrikation verwandten Farben kosten. It has already been suggested that the coloring of the crepe rubber by To achieve coloring of the rubber milk. However, the experiments have given satisfactory results not yet led. There are high-quality dyes required that multiply of the colors otherwise used in rubber production.
Die Erfindung besteht darin, daß beim Brechen des Naturkrepps Farbe und Vulkanisationsstoffe zugegeben und das Brechen bis zum Einreiben der Farbe und des Vulkanisationsstoffes wiederholt wird. The invention consists in that color when the natural crepe breaks and vulcanizing agents added and breaking until the rub-in colour and the vulcanizing substance is repeated.
Es hat sich überraschenderweise gezeigt, daß mit dem Verfahren der Erfindung ein gleichmäßiges Färben des Kreppgummis möglich ist, ohne daß dieser seine Kreppstruktnr verliert. Gegenüber dem bekannten Verfahren zur Herstellung von Kreppgummi wird bei der Erfindung nur das Brechen mehrfach wiederholt, bis die Farbe in den Naturkrepp eingerfeben ist. Es wird aber dabei nicht etwa der Gummi mastiziert. Der Naturkrepp ver-Zert also seine Kreppstrnktur nicht. Zur Verteilung der beim Brechen gerade nur eingeriebenen Farbe und Vulkanisationsstoffe genügt der Durchlanif anschließend durch den Kalander, den die völlig gleichmäßig gefärbte Naturkrepplatte verj:äßt. It has surprisingly been found that with the method of Invention uniform coloring of the crepe rubber is possible without this loses its crepe structure. Compared to the known method of manufacture of crepe rubber in the invention only the breaking is repeated several times until the Color is woven into the natural crepe. But it is not about the rubber masticated. So the natural crepe does not compromise its crepe structure. For distribution the paint and vulcanization substances just rubbed in when breaking is sufficient the Durchlanif then through the calender, which is completely evenly colored Natural crepe board tapered.
Durch das mehrfache Brechen des Naturkrepps wird dieser zwar nicht plastisch, seine Plastizität erhöht sich aber doch etwas. Um dies auszugleichen, werden Vulkanisationsmittel beigegeben, die eine Selbstvuanisation der Gummiplatte herbeiführen und dadurch ein Wachsen der Krepplatten unter den Schuhen verhindern. Bei den bisher bekannten Kreppsohlen war das Wachsen der Sohle unter den Schuhen ein sehr großer Nachteil. Es wurden deswegen Schuhe mit Kreppsohlen vom Verbraucher kaum noch gewünscht. Außerdem wird durch die Zufügung der Vulkanisafionsmittel die Elastizität, Abrieb- und Zerreiß fähigkeit des Fertigproduktes erhöht und die Kreppstruktur bleilbt länger erhalten. By breaking the natural crepe several times, it will not plastic, but its plasticity increases somewhat. To make up for this, Vulcanizing agents are added, which cause the rubber sheet to self-develop and thereby prevent the crepe plates from growing under the shoes. In the previously known crepe soles, the waxing of the sole was under the shoes a very big disadvantage. Because of this, shoes with crepe soles became popular among consumers hardly wanted anymore. In addition, the addition of the vulcanizing agents The elasticity, abrasion and tear resistance of the finished product is increased and the crepe structure is increased stays longer.
