Description
Verfahren zur Herstellung von stark glänzenden Fäden mittels Zellulosexanthogenatlösungen. die Herstellung von stark glänzenden Fäden aus Zellulosexanthogenatlösungen ist auf mannigfache Weise angestrebt worden,, unter anderem auch durch Auspressen der Fäden in Säure. Bei dieser Herstellungsart erreicht man aber nur einen matten Seidenglanz.Process for the production of very shiny threads using cellulose xanthogenate solutions. is the production of very shiny threads from cellulose xanthate solutions been sought in many ways, including by squeezing the Threads in acid. With this type of production, however, you can only achieve a matt silk gloss.
Es wurde nun gefunden, daß beim Auspressen in Säure, z. B. in 2oprozentige Schwefelsäure, ein sehr starker Seidenglanz erzielt wird, wenn zwar die Auspressung der Fäden in diesem Schwefelsämrebade, die Aufwicklung äber in einem, Ammoniumsalzbade erfolgt. Dieses kann zweckmäßig dadurch geschehen, daß man den Körper, welcher die Fäden aufwickelt,' in einem solchen Bade umlaufen läßt. Eigentümlicherweise ist es nicht nötig, dieses Bad. alkalisch zu halten, wie es beim .Spinnen in Ammoniumsalzbädern erfor-, derlich ist. Es genügt, wenn dieses. Bad neutral oder auch schwach sauer gehalten wird. Dadurch, daß dieses Bad sauer gehalten werden kann, ohne den Glanz herabzudrücken, ist es möglich, Ammoniakverluste zu vermeiden. Das Ammoniumsalzbad kann auch dadurch dauernd benutzt werden, daß zu hoch ansteigender Säuregehalt, durch Überschleppen vom Faden aus dem Spinnhade herbeigeführt, mittels Alkalien oder Erdalkalien abgestumpft wird. Durch diese Möglichkeiten kann das Bad in fortlaufendem Kreislauf benutzt wenden, ohne daß ein wesentlicher Verbrauch anAmmoniaksalzen eintritt. Durch den überaus sparsamen Ammoniakverbrauch, welcher sich auf die mechanisdhen Verluste beschränkt, stellt das gegenwärtige Verfahren einen großen wirtschaftlichen Fortschritt dar.It has now been found that when pressed in acid, e.g. B. in 2 percent Sulfuric acid, a very strong silky luster is achieved when although the squeeze the threads in this sulfur seed bath, the winding up in an ammonium salt bath he follows. This can expediently be done by the body, which the Winds up threads, 'circulates in such a bath. Strangely is it doesn't need this bathroom. to keep alkaline, as is the case with .spinning in ammonium salt baths is required. It is enough if this. Bath neutral or slightly acidic is held. Because this bath can be kept acidic without the shine by pressing down, it is possible to avoid ammonia loss. The ammonium salt bath can also be used continuously because the acid content increases too high, brought about by dragging the thread from the Spinnhade, by means of alkalis or alkaline earth is blunted. Through these possibilities, the bath can be continued Use circulation without a substantial consumption of ammonia salts occurs. Due to the extremely economical ammonia consumption, which affects the mechanical Limiting losses, the current process represents a great economic one Progress.
Es ist gleichgültig, ob die Zelluloselösungen, welche nach dem vorliegenden Verfahren versponnen werden sollen, in dem Stadium C 6, also vollkommen frisch, oder in den darauffolgenden Stadien sich befinden. Empfehlenswert ist die Verarbeitung konzentrierter Zelluloselösungen, da diese einen ungemein starken Faden ergeben. Die Badlänge in der Säure ist ebenfalls nicht von sehr großer Wichtigkeit und richtet sich nach der Konzentration der Zelluloselösungen. Z. B. kann bei einer r 5prozentigen Spinnlösung der Faden ungefähr r m lang durch das Säurespinnbad geführt werden.It does not matter whether the cellulose solutions, which according to the present Process are to be spun in stage C 6, i.e. completely fresh, or are in the subsequent stages. The processing is recommended concentrated cellulose solutions, as these make an extremely strong thread. The length of the bath in the acid is also not of great importance and is straightforward depending on the concentration of the cellulose solutions. For example, if r is 5 percent Spinning solution, the thread must be passed through the acid spinning bath for about r m.
Die Badlänge ist zweckmäßig so einzustellen, daß der Faden das Säurefällbad noch in der braun durchsichtigen Färbung, welche der Viskose eigen ist, verläßt.The bath length is expediently adjusted so that the thread penetrates the acid precipitating bath leaves in the transparent brown color which is inherent in viscose.
