Description

Verfahren zum Carbonisieren von Fäden oder Fasern aus Celluloseacetat in Halbwollmaterialien Es wurde gefunden, daß man beim Carbonioieren von Fäden oder Fasern aus Celluloseacetat in Halbwollmaterialien mittels Schwefelsäure eine besonders günstige Wirkung erzielt, wenn man der Schwefelsäureflotte niedere aliphatische Alkohole; insbesondere Isobutylalkohol, zusetzt. Weiterhin würde gefunden:, daß man diese günstige Wirkung noch verbessern kann, wenn man der Flotte außerdem noch Perchlorsäure einverleibt.Process for carbonizing threads or fibers made from cellulose acetate in semi-wool materials It has been found that when carbonizing threads or Cellulose acetate fibers in semi-wool materials by means of sulfuric acid are a special one A favorable effect is achieved if the sulfuric acid liquor is lower aliphatic Alcohols; especially isobutyl alcohol. It was also found: that you can still improve this beneficial effect if you also add to the fleet Perchloric acid incorporated.

Die Wirkung, die sich beider Durchführung des erfindungsgemäßen Verfahrens ergibt, ist besser als diejenige, die man nach bekannten Verfahren mittels Schwefelsäure oder Salzsäure und Ketonen erzielen kann.The effect of performing the method according to the invention is better than that obtained by known methods using sulfuric acid or hydrochloric acid and ketones.

Beispiel .Example .

Ein Halbwollmaterial, das celluloseacetathaltige Beimengungen enthielt, wurde in an sich üblicher Weise unter Verwendung einer Schwefelsäureflotte von 5° Be carbonisiert, der auf roö Gewichtsteile Ware a Gewichtsteile Isobutylalkohoi und a Gewichtsteile 6oo/oige Perchlorsäure zugesetzt worden waren. Es wurde eine restlose Zerstörung der celluloseacetathaltiger_ Beimengungen erzielt.A semi-wool material which contained cellulose acetate-containing additions was carbonized in a conventional manner using a sulfuric acid liquor of 5 ° Be, to which a part by weight of isobutyl alcohol and a part by weight of 600% perchloric acid had been added to each part by weight of goods. The cellulose acetate-containing additions were completely destroyed.
