Description
Frischgesponnene Kunstseide wird vielfach auf solche Spulen aufgewickelt, die eine Lockerung des Gespinstes durch Verringerung ihres Umfanges zulassen. Die Spulenwickel können somit, was für das. Ausschrumpfen der Seide wichtig ist, ohne innere Stützung getrocknet werden.Freshly spun rayon is often wound onto bobbins that have a Allow loosening of the web by reducing its size. The bobbin winding can thus, what is important for the. Shrinking of the silk, without internal Support to be dried.
Nun hat sich herausgestellt, daß insbesondere dann, wenn die Spulenwickel stärker sind, ein bloßes Verringern des Spulenumfanges keineswegs genügt, um ein völliges Ausschrumpfen der Seide zu gewährleisten. Dies kommt daher, weil der an der Außenseite des Wickels befindliche Teil des Fadens unter einer größeren Spannung trocknet als der auf der Wickelinnenseite befindliche Fadenteil. It has now been found that especially when the coil winding is stronger are, a mere reduction of the coil circumference is by no means sufficient for a complete shrinking to ensure the silk. This is because of the on the outside the part of the thread located in the coil dries under a greater tension than the part of the thread located on the inside of the winding.
Die Vermeidung einer inneren Stützung ist bei Spinnkuchen bekannt: In einem FaEe werden die Kuchen in flach zusammengedrücktem Zustand naß behandelt und getrocknet. In einem anderen Falle werden sie vor der Trocknung mittels einer ziemlich verwickelten Vorrichtung eingebuchtet, um 'ein in allen Fadenlagen gleichmäßiges Schrumpfen zu erreichen. Durch diese Maßnahme verlieren indessen die Kuchen die für das spätere Abziehen erwünschte runde Form. Bei einer Einbuchtung der in der Regel viel kleineren Spulenwickel würde dieser Nachteil noch schwerer ins Gewicht fallen. Außerdem =.bedingt ein kleinerer Durchmesser eine engere Faltung, was wieder einer Behinderung· der freien Schrumpfung gleichkommt. Auch ein Flachdrücken der Wickel ist nicht zu empfehlen, zumal wenn sie im Gegensatz zu dünneren Spinnkuchen eine verhältnismäßig große Stärke aufweisen, denn durch das Verformen würde an den Enden des flachgedrückten Wickels wie beim Biegen eines Stabes eine Stauchung der inneren Fadenwindungen und eine Ausreckung der äußeren Fadenlagen eintreten.Avoiding internal support is known with spinning cakes: in a FaEe the cakes are wet treated and dried in a flat compressed state. In another case, they are pretty intricate before drying Device indented to be 'one in all Thread layers to achieve uniform shrinkage. Lose by doing this meanwhile, the cakes have the round shape desired for later peeling. At a Indentation of the usually much smaller bobbin winding would add to this disadvantage be heavier. In addition, a smaller diameter means a narrower one Folding, which again equates to a handicap · free shrinkage. Also a Flattening the wraps is not recommended, especially if they are as opposed to thinner ones Spinning cake have a relatively large thickness, because of the deformation at the ends of the flattened coil, as when bending a rod, the inner thread turns would be compressed and an extension of the outer thread layers occur.
Jetzt setzt die Erfindung ein. Sie besteht darin, daß auf die entspannten Wickel während des Trocknens allseitig ein von außen nach innen wirkender Druck ausgeübt wird. Durch diesen Druck wird das Schrumpfungsbestreben namentlich der äußeren Fädenlagen wesentlich unterstützt, und man gewinnt Fäden, die hinsichtlich ihrer physikalischen Eigenschaften auf ihrer ganzen Länge praktisch einheitlich sind, die also in allen ihren Teilen von wenigstens annähernd der gleichen Beschaffenheit sind wie der die untersten Fadenlagen bildende Teil.Now the invention begins. It consists in being on the relaxed wrap while During drying, a pressure acting from the outside to the inside is exerted on all sides. This pressure causes the tendency to shrink, namely of the outer thread layers substantially supports, and one gains threads, which in terms of their physical Properties are practically uniform over their entire length, that is, in all of theirs Parts of at least approximately the same quality as the lowest Part forming thread layers.

Das Verfahren nach der Erfindung kann außer auf Spulenwickel auch auf Spinnkuchen Anwendung finden.The method according to the invention can also be used on spinning cakes in addition to bobbins Find application.
