Description

Verfahren zum Ätzen von Färbungen auf Polyamidfasern Es wurde, gefunden, daß sich -'F'#rb#u#nge!li äui Po-lya.m,idfa,s#ern besonders gut mit den, Zinksalzen der Formal,dehyds,ulfo,-xyl,s,äure weiß ätzen lassen. Das für das Ätzen von Fä,rbu,iigen, allgemein gebrauchte Foirmal;de-hyd-Na#triu,.ms#u#lfo#xylat ist wenig geeignet, weil die damit hergestellten Weißätzdrucke ausfließen und auf dunklen, oder auf schwerer ätzbaren. Färbungen keine reinen, Weißeffekte damit erhalten werden. Durch einen Zusatz von Zinkoxyd oder Zinkearbonat oder durch andere Zusetze ztirn Natriumsulfoxylat wird keine entsprechende Wirkung erzielt, die spezifisch. für die Zi,n1-,-,Sit,Ifo,xyl-V,crbindunig ist. Die Färbungen auf Polyamidfasern lassen sich durch Formaldehyd-Zinks-ulfoxylat ohne jeden Zusatz leicht weiß ätzen, wodurch der Ätzvorgang verbessert und vereinfacht wird.Process for etching dyeings on polyamide fibers It has been found that -'F '# rb # u # nge!

The Foirmal; de-hyd-Na # triu, .ms # u # lfo # xylat, which is generally used for the etching of Fä, rbu, iigen, is not very suitable because the white etching prints produced with it flow out and onto dark or difficult to etch. Colorings no pure, white effects are obtained with it. The addition of zinc oxide or zinc carbonate or other additives to sodium sulfoxylate does not produce a specific effect. for which Zi, n1 -, -, Sit, Ifo, xyl-V, cr is bonded. The dyeings on polyamide fibers can be easily etched white using formaldehyde-zinc sulfoxylate without any additives, which improves and simplifies the etching process.
