Description
Verfahren zum Trocknen von frischgesponnenen, gewaschenen und gegebenenfalls nachbehandelten laufenden Kunstseidefäden In der Patentschrift 733 r77 ist ein Verfahren beschrieben worden, bei dem man zum Trocknen von frischgesponnenen, gewaschenen und gegebenenfalls nachbehandelten laufenden Kunstseidefäden zu einer frei ausgeschrumpften Kunstseide dadurch gelangt, daß man die zwischen zwei zwangsläufig angetriebenen Fördermitteln lose geführten Fäd:n durch einen warmen Luftstrom zu einer Schlaufe ausblasen und dabei trocknen läßt. Es wurde nun gefunden, daß man zu außerordentlich günstigen Ergebnissen und einer nicht unbeachtlichen Vereinfachung des Verfahrens an sich dadurch gelangt, wenn man die lose geführten Fäden nicht durch einen warmenLuftstrom zu einer Schlaufe ausbläst und @dabei trocknet, sondern wenn man das Ausblasen .der Fäden mit einem gewöhnlichen Luftstrom vornimmt und gleichzeitig infrarote Lichtstrahlen auf die Fäden zur Einwirkung bringt. Während ein warmer Luftstrom die den Fäden anhaftende oder in ihnen enthaltene Flüssigkeit an der Fadenoberfläche zum Verdunsten bringt und daher ,die Trocknung von außen nach innen zu vor sich .geht, erfolgt .die Trocknung durch die infraroten Lichtstrahlen durch eine Art Tiefenwirkung, wobei die Flüssigkeit aus dem Innern der Fäden nach außen hin fortschreitet. Dies hat zur Folge, :daß die mit infraroten Strahlen getrockneten Fäden im Gegensatz zu den mit Hilfe eines warmen Luftstromes -getrockneten Fäden bedeutend weicher-" und schmiegsamer sind., weil bei der Lufttrocknung, immerhin eine gewisse Verhärtung der Fadenoberfläche unvermeidlich ist.Method of drying freshly spun, washed and optionally after-treated running rayon threads In the patent 733 r77 is a process has been described in which one is used to dry freshly spun, washed and optionally post-treated running rayon threads into a freely shrunk Rayon comes by the fact that the between two inevitably driven Conveying loosely guided thread: n through a stream of warm air to form a loop blow out and let it dry. It has now been found that one is too extraordinary favorable results and a not inconsiderable simplification of the procedure by not passing the loosely guided threads through a stream of warm air blows out into a loop and @does it dry, but when you blow out the Making threads with an ordinary air stream and at the same time infrared rays of light brings about action on the threads. During a stream of warm air that pulls the threads liquid adhering to or contained in them on the surface of the thread to evaporate brings and therefore, the drying from the outside to the inside in front of you . goes,. the drying takes place by the infrared light rays through a kind of Depth effect, whereby the liquid from the inside of the threads progresses outwards. This has the consequence: that the threads dried with infrared rays in contrast to the threads that have been dried with the help of a warm air stream much softer " and are more pliable, because at least a certain degree of hardening when air-dried the thread surface is inevitable.
