Description

Verfahren zur Herstellung von aus regenerierter Cellulose bestehenden Füllmaterialien Es ist bekannt, daß man aus frisch gesponnenen groben Einzelfäden aus regenerierter Cellulose durch Tränken mit Harzvorprodukten, wie Harnstofformaldehyd, Drehen, vorzugsweise bis zum Auftreten eines Sekundärdralls, Fixieren der Kräuselung, Trocknen und Nacherhitzen sowie Zurückdrehen künstliche Füllmaterialien für Polsterzwecke u. dgl. von vorzüglichen Eigenschaften herstellen kann. Dem beschriebenen Verfahren haftet nun insofern noch ein Nachteil an, als bei der Aushärtung die benachbarten Einzelfäden bis zu einem gewissen Grad zusammenkleben, was zur Folge hat, daß beim Wiederaufdrehen nicht sofort ein völliges Aufspringen erfolgt und daß das Material auch den üblichen Zupfprozessen einen gewissen Widerstand entgegensetzt. Es wurde nun gefunden, daß man ein bedeutend besser geöffnetes Material erhalten kann, welches sich auch außerordentlich leicht und ohne Schädigung zupfen läßt, wenn den Imprägnierungsbädern eine kleine Menge von oberflächenaktiven Substanzen zugesetzt wird, und zwar speziell solchen, welche auch zur Präparation von Kunstseiden und Zellwolle aus regenerierter Cellulose in Gebrauch sind. Beispiel Ein Bündel von iooo spinnfrischen Einzelfäden, welches aus Kupferoxydammoniakcelluloselösung durch Spinnen in Natronlauge und die üblichen Wäschen erhalten wurde, wird mit einer Lösung getränkt, welche im Liter 6o g Harnstoff, i2o ccm 3'5°/o-igen Formaldehyd, 3 g Ammoniumnitrat_sowie 0,5 g eines Produktes enthält, welches dargestellt ist durch Umsetzung des Monostearinsäureesters des Triäthanolamins mit 2 Mol Äthylenoxyd. Das Fadenbündel wird nun mit einer starken Drehung versehen, und zwar so, daß die einzelnen Windungen überspringen, hierauf getrocknet, i Stunde auf iio'°1 nacherhitzt, zurückgedreht und auf 3ocm Länge geschnitten. Man erhält ein sehr lockeres, gut bearbeitbares Polstermaterial.Process for the manufacture of regenerated cellulose Filling materials It is known that freshly spun coarse single threads can be used from regenerated cellulose by impregnation with resin precursors such as urea formaldehyde, Turning, preferably until a secondary twist occurs, fixing the crimp, Drying and post-heating as well as turning back artificial filling materials for upholstery purposes and the like. Can produce excellent properties. The procedure described there is still a disadvantage to the extent that, during curing, the neighboring ones Single threads stick together to a certain extent, which means that when Turning it up again does not immediately result in a full opening and that the material also offers a certain resistance to the usual plucking processes. It was now found that one can get a significantly better opened material which can also be plucked extremely easily and without damage if the impregnation baths a small amount of surfactants is added, specifically those which are also used for the preparation of rayon and rayon from regenerated Cellulose are in use. Example A bundle of iooo freshly spun single threads, which from copper oxide ammonia cellulose solution by spinning in caustic soda and the usual washes is obtained with a solution soaked, which in liter 60 g urea, 12 o ccm 3'5% formaldehyde, 3 g ammonium nitrate_s as well as Contains 0.5 g of a product which is represented by the reaction of the monostearic acid ester of triethanolamine with 2 moles of ethylene oxide. The thread bundle is now with a strong Rotation provided, in such a way that the individual turns skip, then dried, reheated to 10 ° 1 for an hour, turned back and cut to a length of 30 m. A very loose, easily workable cushioning material is obtained.
