Abstract

Die alkalische Reoxidation von Küpen- und Schwefelk­ üpenfarbstoffen mittels Wasserstoffperoxid ist nur mühsam zu kontrollieren und konstant zu halten. Durch die Ver­ wendung von in der Wärme Hypochlorit abspaltenden Mit­ teln, z.B. p-Toluolsulfonsäure-N-chloramid-Natrium, bei pH-­ Werten über 8 gelingt es, erfindungsgemäß auch Kombinati­ onen aus diesen Farbstoffen mit abweichendem Oxi­ dationsverhalten betriebssicher zu reoxidieren. Gleichzeitig ergab sich die Gelegenheit, den notwendigen Seifvorgang mit der Reoxidation zu vereinen. The alkaline reoxidation of vat and sulfur Bulb dyes using hydrogen peroxide are tedious to control and keep constant. By ver Use of mites which release hypochlorite in the heat means, e.g. p-toluenesulfonic acid-N-chloramide sodium, at pH Kombinati also achieves values above 8, according to the invention onen from these dyes with different oxi dation behavior to reliably reoxidize. At the same time there was an opportunity to do the necessary soaping to combine with reoxidation.
