Description

Verfahren zur Entfernung der bei der Kunstseidenherstellung nach dem Streckspinnverfahren durch das Reißen von Kapillarfäden entstehenden Verdickungen oder Knötchen. Gegenstand der Erfindung ist eine weitere Ausbildung bzw. eine Abänderung des durch Patent 397 85; geschützten Verfahrens zur Behändlung von feuchter Kunstseide, wobei die Seide in Strangform auf sich drehende Rollen gelegt und durch letztere abwechselnd ruckweise gespannt und gelockert wird, während gleichzeitig die Trocknung der Seide torgenommen wird. Durch diese Behandlung «-erden einerseits die verdickten Fadenenden (Knötchen) aus dem Strang entfernt und anderseits die Fäden geglättet und weich gemacht.Process for the removal of the artificial silk production according to the Draw spinning process resulting from the breakage of capillary threads or nodules. The invention relates to a further training or a modification that by patent 397,85; protected process for the treatment of moist rayon, the silk being laid in rope form on rotating rollers and through the latter is alternately tightened and loosened in jerks, while drying at the same time the silk is gunned down. Through this treatment, on the one hand, the thickened ones are earthed Thread ends (nodules) removed from the strand and, on the other hand, the threads smoothed and softened.

Bei der im Hauptpatent beschriebenen Arbeitsweise wird das Verfahren mit frisch Iresponnener und von den voraufgegangenen Bädern noch feuchter Seide durchgeführt. Diese Ausführungsform des Verfahrens hat jedoch den Nachteil, daß die Seide in diesem Zustand noch verhältnismäßig wenig reißfest ist; die Schläge, die dem Strang durch das ruckweise Anspannen und Lockern der Rollen erteilt «-erden, dürfen daher nicht sehr stark sein, da sonst unversehrte Fäden reißen. können. Deshalb muß die Behandlung mit einer gewissen Vorsicht durchgeführt werden und dauert infolge der begrenzten Wirkung gelegentlich unerwünscht lange.In the procedure described in the main patent, the method with silk freshly sunbathed and still damp from the previous baths carried out. However, this embodiment of the method has the disadvantage that the silk in this condition is still relatively weak; the punches, which are given to the strand by jerky tensioning and loosening of the rollers "-earth, must therefore not be very strong, otherwise intact threads will tear. can. That's why the treatment must be carried out with a certain degree of caution and consequently it lasts the limited effect occasionally for an undesirably long time.

Nun wurde gefunden, daß die Wirkung der Rollen viel intensiver gestaltet werden kann, und daß ein noch besserer Erfolg auch in bezug auf das Lockern (Öffnen) der Kunstseide erzielt wird, wenn gemäß der Zusatzerfindung die Kunstseide vorher schon einmal getrocknet war und für die Behandlung erneut angefeuchtet wird. Die durch die Trocknung besser durchkoagulierte Seide ist nämlich bei einer abermaligen Feuchtung widerstandsfähiger und kann ausgiebiger geschlagen werden, ohne daß unversehrte Fäden gefährdet werden. Durch diese ausgiebigere Behandlung werden die abgerissenen verdickten Fadenenden rascher entfernt, und man erzielt auch in bezug auf Glätte und Weichheit bzw. Lockerheit eine vollkommenere Ware.It has now been found that the effect of the roles is much more intense can be, and that an even better success also with regard to loosening (opening) the rayon is achieved if, according to the additional invention, the rayon beforehand has already dried and is re-moistened for treatment. the Silk that coagulates better through drying is in fact with a repeated one Moisture resistant and can be beaten more extensively without being intact Threads are endangered. With this more extensive treatment, the torn off thickened thread ends are removed more quickly, and smoothness is also achieved and softness or looseness a more perfect product.

Die praktische Durchführung des neuen Verfahrens kann z. B. entweder in der Weise geschehen, daß man den frisch gesponnenen und mit den verschiedenen Bädern behandelten Strang zunächst trocknet, dann nochmals feuchtet und ihn hernach durch die im Hauptpatent beschriebene Strecktrocknung weiterbehandelt. Man kann aber auch das Verfahren derart ausführen, daß die Streck-Schwing-Behandlung mit dem vorher getrockneten Strang begonnen wird und eine allmähliche Befeuchtung während dieser Streck-Schwing-Behandlung vorgenommen wird, an welche sich gemäß dem Hauptpatent der Trockenvorgang anschließt. Hierbei wird als weiterer Vorteil eine ganz gleichmäßige Durchfeuchtung des Stranges erzielt. die der ohnehin erforderlichen und bisher durch einfaches Aushängen in einem wasserbesprühten Raum bewirkten Feuchtung erheblich überlegen -ist und zugleich diese bisherige Nachbefeuchtung ersetzt. Das vorliegende Verfahren bedeutet infolgedessen auch keinerlei besonderen Zeitaufwand, da die Feuchtung der getrockneten Stränge auf alle Fälle durchgeführt werden muß.The practical implementation of the new method can, for. B. either done in such a way that you can get the freshly spun and with the different Baths treated strand first dries, then again moistened and afterwards it further treated by the stretch drying described in the main patent. One can but also carry out the method in such a way that the stretch-vibration treatment with the previously dried strand is started and a gradual moistening during this stretching-vibrating treatment is carried out, which is based on the main patent the drying process follows. Another advantage here is a very even Moisture penetration of the strand achieved. that of the already necessary and so far by simply hanging it out in a water-sprayed room caused a significant amount of moisture superior - is and at the same time replaces this previous rewetting. The present As a result, the process does not involve any special expenditure of time, since the humidification the dried strands must be carried out in any case.
