Description
Verfahren zur Herstellung von Geweben und Gewirke aus linearen Superpolyamiden mit verstärkter, gleichbleibender Haftfähigkeit.Process for the production of woven and knitted fabrics from linear superpolyamides with increased, constant adhesion.
Es ist bekannt, textile Gewebe aus Naturgarnen oder -fäden sowie Kunstseide oder Zellstofffäden auf der Zellulosebasis mit einem haftfähigen Überzug zu versehen. Diese Gewebe zeigen aber, je nach dem verwendeten Textilgut, einen mehr oder weniger starken Verschleiß, der auch bei Verwendung von Naturseide noch verhältnismäßig groß ist.It is known to provide textile fabrics made of natural yarns or threads and also artificial silk or cellulose threads on the cellulose basis with an adhesive coating. However, depending on the textile material used, these fabrics show more or less severe wear and tear, which is still relatively high even when natural silk is used.
Dieser Nachteil wurde dadurch überwunden, dass anstelle der genannten Fäden Folienstreifen, Garne oder Fäden aus linearen Superpolyamiden verwendet werden und die daraus hergestellten Gewebe oder Gewirke mit einer polymerisierbaren Polyvinylchloridpaste behandelt und die Paste polymerisiert wurde. Der hierbei erzielte Effekt ist derart, dass ein solches Gewebe oder Gewirke bei gleicher mechanischer Beanspruchung eine wesentlich höhere Lebensdauer hat oder bei gleicher Lebensdauer bedeutend stärkeren mechanischen Beanspruchungen ausgesetzt werden kann als vorgenanntes. Die Haftfähigkeit ist eine verhältnismäßig große und kann als konstant angesprochen werden. Solche Gewebe können als Treibriemen, Transportbänder usw. verwendet werden.This disadvantage was overcome by using foil strips, yarns or threads made of linear superpolyamides instead of the threads mentioned, and treating the woven or knitted fabrics made from them with a polymerizable polyvinyl chloride paste and polymerizing the paste. The effect achieved here is such that such a woven or knitted fabric has a significantly longer service life with the same mechanical stress or can be exposed to significantly greater mechanical stresses than the aforementioned with the same service life. The adhesion is relatively large and can be addressed as constant. Such fabrics can be used as drive belts, conveyor belts, etc.
Beispiel:Example:
Herstellung eines leistungsfähigen Treibriemens, bei dem die im Laufe des Gebrauches oft zu wiederholende Präparierung fortfällt. Es wird ein Treibriemen hergestellt, dessen Kette aus linearen Polyamiden besteht, mit Polyvinylchloridpaste präpariert und diese anschließend durch Erhitzen auf 170° innerhalb von 5 Minuten polymerisiert. Der hergestellten Treibriemen zeigt dieselbe Festigkeit wie ein solcher aus Leder, in Verbindung mit der gleichen Haftfähigkeit eines Balata- oder Gummiriemens. Die Lebensdauer ist auf Grund der guten Reiß- sowie Scheuerfestigkeit der Polyamidkette außerordentlich beträchtlich.Manufacture of a high-performance drive belt that eliminates the need for preparation that has to be repeated in the course of use. A drive belt is produced, the chain of which consists of linear polyamides, prepared with polyvinyl chloride paste and this is then polymerized by heating to 170 ° within 5 minutes. The drive belt produced shows the same strength as one made of leather, in connection with the same adhesiveness of a balata or rubber belt. The service life is extremely long due to the good tear resistance and abrasion resistance of the polyamide chain.
