KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung beruht auf der Beobachtung, daß man durch Verspinnen einer Zelluloseacetatlösung Fäden erhalten kann, welche beim Färben keine Farbe annehmen und sich daher als Zier- und Effektfäden für gemischte, im Stück mehrfarbig zu färbende Gewebe verwerten lassen, sofern man bei der Verarbeitung dieser Zelluloseacetatfäden starke Alkalien völlig ausschließt undThe present invention is based on the observation that by spinning a cellulose acetate solution can obtain threads which do not take on any color during dyeing and can therefore be used as decorative and effect threads for mixed fabrics to be dyed in multiple colors in one piece, provided that one when processing these cellulose acetate threads, it completely excludes strong alkalis and
ίο dadurch die teilweise oder gänzliche Wiederabspaltung des Essigsäurerestes vermeidet.ίο thereby the partial or total spin-off of the acetic acid residue.
Um zu verhüten, daß das Zelluloseacetat bei der Vorbehandlung der gemischten Gewebe vor dem eigentlichen Färbeprozeß zersetzt wird, können die Zelluloseacetatfäden noch mit Nitrozellulose überzogen sein, welche besonders gegen Alkalien und basische Farbstoffe, aber auch gegen heiße Säuren widerstandsfähiger ist als Zelluloseacetat.To prevent cellulose acetate from pretreating the mixed fabrics is decomposed before the actual dyeing process, the cellulose acetate threads can still be coated with nitrocellulose, which especially resistant to alkalis and basic dyes, but also more resistant to hot acids is called cellulose acetate.
Die Herstellung des den Erfindungsgegenstand bildenden gemischten Gewebes kann demnach beispielsweise folgendermaßen geschehen :The production of the mixed fabric forming the subject of the invention can therefore happen, for example, as follows:
Eine farblose oder gefärbte Lösung von Zelluloseacetat in Essigsäureanhydrid, Eisessig, Chloroform usw. wird in üblicher Weise versponnen, wobei als Fäll- und Waschmittel reines oder schwach ammoniakalisches Wasser verwendet wird. Die erhaltenen Fäden werden sodann mehrmals durch eine verdünnte Lösung von Nitrozellulose in reinem oder schwach alkoholhaltigem Äther gezogen und mit anderen Textilfaden verwebt. Beim Ausfärben der so hergestellten Gewebe im Stück, welches bei Mischungen mit pflanzlichen Fasern am besten mit direkt ziehenden Baumwollfarbstoffen, besonders aber mit Schwefelfarbstoffen, bei Mischungen mit Wolle mit sauren Wollfarbstoffen geschieht, nehmen die Zelluloseacetatfäden keinen Farbstoff auf und erscheinen daher weiß bezw. in der vorher angewendeten Farbe. Der Nitrozelluloseüberzug verhütet hierbei eine Zersetzung des Zelluloseacetats bei der Vorbehandlung mit alkalischen Flüssigkeiten und beim Ausfärben mit basischen Farbstoffen,A colorless or colored solution of cellulose acetate in acetic anhydride, glacial acetic acid, Chloroform etc. is spun in the usual way, using as a precipitant and detergent pure or weakly ammoniacal water is used. The threads obtained are then drawn several times through a dilute solution of nitrocellulose in pure or slightly alcoholic ether and interwoven with other textile thread. When dyeing the fabric produced in this way in one piece, which, in the case of blends with vegetable fibers, is best with direct cotton dyes, but especially with sulfur dyes, which happens when blends with wool with acidic wool dyes, take them Cellulose acetate threads do not have any dye and therefore appear white bezw. in the before applied color. The nitrocellulose coating prevents the decomposition of the Cellulose acetate when pretreating with alkaline liquids and when coloring with basic dyes,
