Description

Verfahren zur Verbesserung des Spinnvorganges bei der Herstellung von Viscosekunstseide Bei der Herstellung von Viscosekunstseide ist der störungsfreie Verlauf des eigentlichen Spinnvorganges im Spinnbade von entscheidender Bedeutung für die ganze Fabrikation. Dieser Spinnvorgang wird zum großen Teil durch die Verschmutzung der Düsen beeinflußt, sei es, daß sich in den Spinnlöchern oder am Ausgang der Spinnlöcher. ausgefällte Cellulose, Schwefelablagerungen,. Harzteilchen u. dgl. ansetzen, die Löcher verengen oder gar verstopfen oder wenigstens am Ausgang der Löcher den regelmäßigen Durchgang der Fäden stören und hindern. Die Störungen machen sich besonders in den im allgemeinen in der Industrie üblichen sauren, z. B. schwefelsauren Spinnbädern bemerkbar. Die besagte Verschmutzung der Düsen führt zu Unregelmäßigkeiten in der Einzelfadenzahl innerhalb eines bestimmten Fadenschaftes, .ferner zu unregelmäßig dicken Kapillarfäden und daher auch zu unregelmäßigen Anfärbungen. Eine besonders unangenehme Begleiterscheinung ist die Bildung von Spinnhäkchen, das öftere Abreißen der Fäden oder mindestens ein häufig notwendiger Wechsel der Düsen, was alles mit vermehrter Arbeit, Ausfall an Produktion, Verlust von Viscose, vermehrter Zahl von Knoten und minderwertiger Qualität verbunden ist. Es ist daher verständlich, daß sich die Industrie bemüht, den Zustand der Düsen und ihre Reinhaltung aufs peinlichste zu verfolgen. Es ist nun die überraschende Beobachtung gemacht worden, daß, wenn man gewisse kationaktive Fettstoffe in das saure Spinnbad bringt, eine ganz wesentliche Verbesserung des Spinnprozesses eintritt. Kationaktive Fettstoffe sind oberflächenaktive Körper der Fettreihe, welche die für die Oberflächenaktivität verantwortliche Fettkette im Kation tragen, wie z. B. Lauryltriäthylammoniumsulfat oder Lecithin.Process for improving the spinning process during manufacture of viscose artificial silk In the production of viscose artificial silk the trouble-free The course of the actual spinning process in the spinning bath is of decisive importance for the whole production. This spinning process is in large part due to pollution the nozzle affects, whether that is in the spinning holes or at the exit of the spinning holes. precipitated cellulose, sulfur deposits ,. Attach resin particles and the like that Narrow or even clog holes or at least the regular ones at the exit of the holes Interfere and prevent the passage of the threads. The disturbances are particularly evident in the generally acidic ones commonly used in industry, e.g. B. sulfuric acid spinning baths noticeable. Said soiling of the nozzles leads to irregularities in the Number of single threads within a certain thread shaft, furthermore too irregular thick capillary threads and therefore irregular staining. One special An unpleasant side effect is the formation of spider hooks, the frequent tearing off of the threads or at least a frequently necessary change of the nozzles, everything with increased work, loss of production, loss of viscose, increased number of Knots and inferior quality is associated. It is therefore understandable that The industry makes every effort to keep the condition of the nozzles and their cleanliness as painstakingly as possible to pursue. The surprising observation has now been made that if Certain cationic fatty substances are brought into the acidic spinning bath, an essential one Improvement of the spinning process occurs. Cation-active fatty substances are surface-active Body of the fat series, which is the fat chain responsible for surface activity carry in the cation, such as B. Lauryltriethylammoniumsulfat or lecithin.

Als ein besonders wirksamer Körper dieser Art hat sich Laurylpyridiniumsulfat erwiesen, das schon in ganz kleinen Quantitäten den gewünschten Erfolg bringt. Als Begleiterscheinung bei der Verwendung dieser Körper im Spinnbad macht sich eine Zusammenballung und leichte Abfiltrierbarkeit des im Spinnbade vielfach kolloidal vorhandenen Schwefels bemerkbar. Bei dieser so bewirkten Entfernung des Schwefels, der ja selbst eine Verünreinigung darstellt, dürften auch andere gelöste oder in Suspension vorhandene Schmutzteilchen mitgerissen und aus dein Spinnbad ausgeschieden werden.Lauryl pyridinium sulfate has proven to be a particularly effective body of this type proven that brings the desired success even in very small quantities. as A side effect when using this body in the spinning bath makes itself one The agglomeration and easy filterability of the in the spinning bath is often colloidal presence of sulfur noticeable. With this removal of the sulfur, which is itself a defilement, other dissolved or in Suspension entrained existing dirt particles and excreted from your spinning bath will.

Es sind schon Zusätze zu Spinnbädern, wie Formaldehyd oder Sulfurierungsprodukte von Ölen und Fetten, vorgeschlagen worden, welche das Spinnbad von Verunreinigungen freihalten sollten. Soweit es sich hierbei um Fettstoffe handelt, enthalten diese den Fettkern im Anion. Durch Zusatz solcher Stoffe läßt sich aber ebensowenig wie finit Formaldhy d der durch kationaktiv e Fettstoffe erzielbare Effekt, nämlich die Vermeidung des Zuwachsens der Düsenöffnungen, erreichen. Gerade diese Wirkung ist aber für einen einwandfreien Verlauf des Spinnens ausschlaggebend.There are already additives to spinning baths, such as formaldehyde or sulfurization products of oils and fats, has been suggested to remove impurities from the spinning bath should keep clear. As far as these are fatty substances, they contain the fat core in the anion. But just as little can be done by adding such substances as finite Formaldhy d the achievable through cation-active fatty substances The effect, namely the avoidance of the nozzle openings becoming blocked, can be achieved. Just however, this effect is crucial for the smooth running of the spinning process.

Beispiel i Beim Verspinnen üblicher Viscose durch die bekannten feinlöcherigen Edelinetalldüsen in einem sauren Spinnbade, welches im wesentlichen aus Schwefelsäure, Vatriumsulfat, , Ammoniumsulfat und kleinen Beträgen von Zinksulfat zusammengesetzt sein mag und welches im allgemeinen zu recht vielen Spinnschwierigkeiten wegen Verschmutzung der Düsen zu führen pflegt, wird eine kleine Quantität von 0,04 Gewichtsprozent Laurylhyridiniumsulfat hinzugefügt. Die Zugabe bewirkt auf lange Zeit hinaus ein einwandfreies Spinnen.Example i When spinning conventional viscose through the well-known fine-perforated noble metal nozzles in an acidic spinning bath, which may be composed essentially of sulfuric acid, sodium sulphate, ammonium sulphate and small amounts of zinc sulphate and which generally leads to a lot of spinning difficulties due to soiling of the nozzles, becomes a small quantity of 0.04 weight percent laurylhyridinium sulfate added. The addition causes perfect spinning for a long time.

Beispiel 2 An Stelle der in Beispiel i genannten o,o4Gewichtsprozente Laurylpiridiniumsulfat werden dem Spinnbad o,i Gewichtsprozent Lauryltriäthylammoniumsulfat einverleibt.Example 2 Instead of the o, o4 weight percentages mentioned in example i Laurylpiridinium sulfate are added to the spinning bath 0.1 percent by weight of lauryl triethylammonium sulfate incorporated.

Das Lauryltriäthylammoniumsulfat wird so gewonnen, daB Laurylalkohol durch Jod und roten Phosphor in das Jodid übergeführt und dann durch Erwärmen mit einer äquimolekularen Menge Triäthylamin in das quaternäre Ammoniumjodid umgesetzt wird. Beim Lösen des jodids in schwefelsaurem Spinnbad entsteht Lauryltriäthylammoniumsulfat nachstellender Strukturformel, wobei die Bezeichnung Lauryl durch die Dodccylgruppe C,2 H." charakterisiert wird. Beispiel 3 . Beim Hinzufügen von 0,04 Gewichtsprozent Cetylstearylpyridiniumsulfat von der Strukturformel zum Spinnbad an Stelle von o,o4 Gewichtsprozent Laurylpyridiniumsulfat wie im Beispiel i wird unter sonst gleichen Bedingungen derselbe gute Effekt erzielt:'-The lauryl triethylammonium sulfate is obtained in such a way that lauryl alcohol is converted into iodide by iodine and red phosphorus and then converted into quaternary ammonium iodide by heating with an equimolecular amount of triethylamine. When the iodide is dissolved in a sulfuric acid spinning bath, lauryl triethylammonium sulfate is formed, which has a structural formula that follows the structure, the designation lauryl being characterized by the dodccyl group C, 2 H. ". Example 3. When adding 0.04 weight percent cetostearyl pyridinium sulfate of the structural formula to the spinning bath instead of 0.04 percent by weight of laurylpyridinium sulfate as in example i, the same good effect is achieved under otherwise identical conditions: '-
