Description
Verfahren zur Entfernung von Acetatseide und Cellulosefasern aus Wolle und Wollgespinsten Durch die zunehmende Verarbeitung von Acetatseide, Polyamidfasern usw. in wollenen Textilien ergibt sich die Aufgabe, zur Wiederverwertung von wollhaltigen Abfällen die Acetatseide und wollfremde Anteile daraus zu entfernen. Nach dem üblichen Karbonisierverfahren, wobei Wolle mit Mineralsäuren, wie Schwefelsäure oder Salzsäure bzw. mit diese Säuren abspaltenden Verbindungen, wie Natriumbisulfat oder Aluminiumchlorid, behandelt werden, lassen sich nur pflanzliche. Beimengungen und Cellulosefasern entfernen. Die Acetatseide wird dabei nicht zerstört.Process for removing acetate silk and cellulose fibers from wool and wool spun due to the increasing processing of acetate silk and polyamide fibers etc. In woolen textiles there is the task of recycling wool-containing Waste to remove the acetate silk and foreign parts from it. According to the usual Carbonization process in which wool is mixed with mineral acids, such as sulfuric acid or hydrochloric acid or with compounds that split off these acids, such as sodium bisulfate or aluminum chloride, can only be treated herbal. Admixtures and cellulose fibers remove. The acetate silk is not destroyed.
Eine Karbonisierung, bei der vorgetrocknete acetatseidehaltigeWollgespinste mit einem wasserfreien gasförmigen Gemisch von Siliciumtetrachlorid und Methylenchlorid behandelt werden, läßt die Acetatseidenteile bereits deutlich angegriffen und morsch erscheinen; sie lassen sich aber nur schwer aus dem Material entf ernen.A carbonation in which pre-dried silk-acetate spun yarns with an anhydrous gaseous mixture of silicon tetrachloride and methylene chloride treated, leaves the acetate silk parts already clearly attacked and rotten appear; however, they are difficult to remove from the material.
Es ist auch vorgeschlagen, andere wasserfreie Halogenide wie Sulfurylchlorid im Gemisch mit Methylenchlorid zu verwenden, jedoch ergeben diese bei der Gaskarbonisierung keine zufriedenstellende Zerstörung der Acetatseidenanteile.It is also suggested to use other anhydrous halides such as sulfuryl chloride to be used in a mixture with methylene chloride, but these result in the gas carbonation no satisfactory destruction of the acetate silk portions.
Es wurde nun gefunden, daß eine einwandfreie Karbonisierung sowohl der Cellulose- als auch der Acetatseidenanteile erfolgt, wenn man das VOTgetrocknete Fasermaterial in zwei Stufen mit zwei verschiedenen, an sich bekannten Karbonisiermitteln in Gasform nacheinander behandelt, wobei zuerst ein wasserfreies Gasgemisch aus Sulfurylchlorid und Methylenchlorid und anschließend ein wasserfreies Gasgemisch aus Siliciumtetrachlorid und Methylenchlorid bei erhöhter Temperatur zur Anwendung gelangen.It has now been found that proper carbonation both the cellulose as well as the acetate silk components takes place when the VOT is dried Fiber material in two stages with two different carbonizing agents known per se Treated in gaseous form one after the other, first consisting of an anhydrous gas mixture Sulfuryl chloride and methylene chloride and then an anhydrous gas mixture of silicon tetrachloride and methylene chloride at elevated temperature for use reach.
Es wurde weiterhin festgestellt, daß die Reihenfolge der einwirkenden Karbonisierungsmittel in der beschriebenen Art von Bedeutung für den Karbonisiereffekt ist. Auch Mischungen der beiden gasförmigen Karbonisiermittel haben nicht die Wirkung wie die Durchführung in zwei Stufen hintereinander.It was also found that the order of the acting Carbonizing agents in the type described are of importance for the carbonizing effect is. Mixtures of the two gaseous carbonating agents also do not have the effect like performing in two stages in a row.
Das Kennzeichen des erreichten Effektes der erfindungsgemäßen Arbeitsweise ist, daß sich die Nichtwollebestandteile- aus dem Material auf übliche Weise herausklopfen lassen, während bei Anwendung nur eines der verwendeten Gasgemische für sich allein - auch bei entsprechend langer Behandlungszeit - die zu karbonisierenden Faseranteile erst durch intensives Reiben und mechanisches Durchwalken aus den Wollfasern entfernt werden können.The characteristic of the effect achieved by the method according to the invention is that the non-wool components can be knocked out of the material in the usual way, while when only one of the gas mixtures used is used on its own - even with a correspondingly long treatment time - the fiber portions to be carbonized only by intensive rubbing and mechanical fulling can be removed from the wool fibers.
Beispiel 1 Acetatseidehaltige Wollabfälle werden 1 -bis 11/2 Stunde in den üblichen Gaskarbonisieröfen durch Warmluft bei 100 bis 105' C vorgetrocknet, bis sie praktisch wasserfrei sind. Dann läßt man in den Ofen ein Gasgemisch aus 10 Teilen S ulfurylchlorid, 90 Teilen Methylenchlorid einströmen und bei 105 bis 110' C während 1 bis 11/2 Stunde auf das Material einwirken. EXAMPLE 1 Wool waste containing acetate silk is predried for 1 to 11/2 hours in the customary gas carbonizing ovens by means of warm air at 100 to 105 ° C. until it is practically anhydrous. Then allowed a gas mixture of 10 parts of S ulfurylchlorid in the oven, 90 parts of methylene chloride and flow at 105 to 110 'C for 1 to 11/2 hours affect the material.
Anschließend wird ein zweites Gasgemisch aus 10 Teilen Siliciumtetrachlorid, 90 Teilen Methylenchlarid eingeleitet, das man ebenfalls 1 bis 11/2 Stunde bei 105 bis.110' C auf das Material einwirken läßt.A second gas mixture of 10 parts of silicon tetrachloride and 90 parts of methylene chloride is then passed in, which is also allowed to act on the material for 1 to 11/2 hours at 105 to 110 ° C.
Zum Schluß wird das Reaktionsgas durch trockene Warmluft oder durch ein trockenes inertes Gas, z. B. Stickstoff, aus dem Karbonisierofen herausgedrückt. Das Gasgemisch läßt sich ohne weiteres kondensieren und im Kreislauf zur Herstellung der Karbonisiergase weiterverwenden.Finally, the reaction gas is through dry warm air or through a dry inert gas, e.g. B. nitrogen, pressed out of the carbonation furnace. The gas mixture can easily be condensed and recycled for production continue to use the carbonation gases.
In dem karbonisierten Material sind Acetatseide-und Zelluloseanteile zerstört, so daß sie durch Klopfen auf übliche Art und Weise aus der Ware entfernt werden können.The carbonized material contains acetate silk and cellulose destroyed, so that they are removed from the goods by knocking in the usual way can be.
Beispiel 2 Die Karbonisierung acetatseidenhaltigerWollabfälle wird in der gleichen Weise, wie im Beispiel 1 beschrieben, durchgeführt mit dem Unterschied, daß als erstes Reaktionsgas ein Gemisch von 20 Teilen Sulfurylchlorid, 80 Teilen Methylenchlorid verwendet wird. Die erste Phase der Gaskarbonisierung läßt sich dann ungefähr auf 1 Stunde abkürzen.EXAMPLE 2 The carbonization of wool waste containing acetate silk is carried out in the same way as described in Example 1 , with the difference that a mixture of 20 parts of sulfuryl chloride and 80 parts of methylene chloride is used as the first reaction gas. The first phase of gas carbonization can then be shortened to approximately 1 hour.
