Description

Verfahren zur Herstellung von Weiß- und Buntätzen auf gefärbten Garnen oder Geweben aus regenerierter Cellulose Es ist bekannt, Garne oder Gewebe aus natürlicher oder regenerierter Cellulose, welche mit ätzbaren Eisfarben gefärbt sind, durch Aufdruck von Reduktionsätzpasten, welche Natriumformaldehydsulfoxylat, Alkali und Verdickungsmittel enthalten, und anschließendes Dämpfen weiß zu ätzen. Auf demselben Wege werden Buntätzen erhalten, wenn man den Reduktionsätzen ätzbeständige Farbstoffe, beispielsweise Küpenfarbstoffe, ztufügt, welche beim Dämpfen fixiert werden.Process for the production of white and colored etchings on dyed yarns or fabrics made from regenerated cellulose It is known to make yarns or fabrics made from natural or regenerated cellulose, which are colored with etchable ice paints Imprint of reduction etching pastes, which contain sodium formaldehyde sulfoxylate, alkali and Contain thickener, and subsequent steaming white to etch. On the same Colored etchings are obtained if the reduction etchings contain etch-resistant dyes, for example vat dyes, which are fixed during steaming.

Es wurde nun gefunden, daß man weiße und bunte Reduktionsätzen herstellen kann, wenn man die genannten Ätzdruckpasten auf Fasergut aus regenerierter Cellulose, welches mit ätzbaren Azopigmenten spinngefärbt ist, aufdruckt und dämpft. Diese Tatsache war nicht vorauszusehen, da die Pigmentteilchen wesentlich gröber sind als bei einer, üblichen Färbung mit Eisfarben. Außerdem ist bei der Spinnfärbung das Pigmnent durch die ganze Masse der Faser verteilt, während es bei der üblichen Färbung vorwiegend in den äußeren Schichten der Faser liegt. Trotzdem wird nach dem vorliegenden Verfahren eine Zerstörung des ätzbaren Azopigmentes auch im Innern der Faser bewirkt. Die Ätzbestandteile lassen sich durch die übliche Nachbehandlung mit heißen alkalischen Bädern restlos entfernen.It has now been found that white and colored reduction etching can be produced can, if one uses the mentioned discharge printing pastes on fiber material made of regenerated cellulose, which is spun-dyed with etchable azo pigments, prints and dampens. These The fact could not be foreseen since the pigment particles are much coarser than with a usual coloring with ice colors. In addition, is in the spin dyeing the pigment is distributed through the whole mass of the fiber, while it is the usual Coloring lies predominantly in the outer layers of the fiber. Nevertheless, after the present process also destroys the etchable azo pigment inside the fiber causes. The etching components can be removed through the usual post-treatment remove completely with hot alkaline baths.

Durch Zusatz von ätzbeständigen Farbstoffen, z. B. Küipenfarbstoffen, ätzbeständigen basischen oder substantiven Farbstoffen, zu den Ätzdruckpasten können die Ätzmuster auch bunt illuminiert werden. Der Zusatz von Netz- oder Lösungsmitteln, z. B. Fettalkoholsulfonaten, Glycerin, Thiodiglykol, sowie von reduktionsfördernden Mitteln, z. B. Anthrachinon, fördert die Ätzwirkung der Druckpaste. Beispiele , Eine rotgefärbte Viscosekunstseide wird durch Zusatz von 2 °% des unlöslichen Azofarbstoffes I Amino-2-methyl-d-chlorbenzoli - (2 ', 3'- Oxynaphtoy lainino) - 2 - methy l - d.-chlorbenzol zur Spinnlösung erbalten. Ein Gewebe aus dieser spinngefärbten Viscosekuztstseirde wird, mit folgernden Druckpasten bedruckt: a) i 5og N atriumformaldehvdsulfoxylat 235g Wasser I00g Pottasche 5oog Stärle-Tragattt-Verdickung I 5 g Anthrachinon Iooo g I) Ioog 2o %iger Teig des Farbstoffes Nr. I3I4 (Schultz Farbstofftabel- len, 7. Auflage) 3o g Thiodiglylol 3o g Glycerin I8o g Wasser 42og Stärle-Britischgummi-Ver- dickung I2o g Natriumformaldehydsulfoxylat sog Pottasche I000g Nach dem Drucken wird die Ware getrocknet. 3 his Io Minuten im Schnelldämpfer nit luftfreiem Dampf gedämpft, anschließend rüindlich mit Wasser gespült, in einem kochend heißen Bade von 5g Soda im Liter behandelt, gespült und getrocknet. Man erhält mit Druckpaste a) weiße, mit Druckpaste b) lebhafte blaue Ätzmnuster auf rotem Grunde.By adding etch-resistant dyes, e.g. B. Küipen dyes, etch-resistant basic or substantive dyes, for the discharge printing pastes, the etching patterns can also be illuminated in color. The addition of wetting agents or solvents, e.g. B. fatty alcohol sulfonates, glycerol, thiodiglycol, and reduction-promoting agents, eg. B. Anthraquinone, promotes the etching effect of the printing paste. Examples, A red-colored viscose rayon is obtained by adding 2% of the insoluble azo dye I amino-2-methyl-d-chlorobenzoli - (2 ', 3'-Oxynaphtoy lainino) - 2 - methyl l - d.-chlorobenzene to the spinning solution. A fabric made of this spun-dyed Viscosekuztstseirde is printed with the following printing pastes: a) i 5og sodium formaldehyde sulfoxylate 235g water I00g potash 5oog starch-Tragattt-thickening I 5 g of anthraquinone Iooo g I) Ioog 20% dough of the dye No. I3I4 (Schultz dye table len, 7th edition) 30 g thiodiglylol 30 g glycerine 180 g of water 42og strength British rubber con thickening I2o g of sodium formaldehyde sulfoxylate so-called potash I000g After printing, the goods are dried. Steamed for 3 to 10 minutes in a quick steamer with air-free steam, then rinsed with water, treated in a boiling hot bath of 5g soda per liter, rinsed and dried. White etching patterns are obtained with printing paste a) and vivid blue etching patterns on a red background with printing paste b).
