Description

Verfahren zur Oxydation (Chlorierung) tierischer Textilgebilde, wie Wolle, Seide u. dgl. Zur Oxydation bzw. Chlorierung von Wolle und anderen Tierhaaren wurden bisher lediglich Hypochlorite (Chlorkalk) und Chlor verwendet.Process for the oxidation (chlorination) of animal textiles, such as Wool, silk and the like for the oxidation or chlorination of wool and other animal hair only hypochlorite (chlorinated lime) and chlorine have been used so far.

Es wurde nun die sehr wichtige Beobachtung gemacht, daß aromatische Sulfosäurechloramide, insbesondere das p-Toluolsulfochloramid (Chem. Centr. 1905, Bd.I, Seite lolo), deren Chloratom ähnliche Reaktionen zeigt wie das Chloratom der Hypochlorite, neue technische Erfolge ermöglichen.The very important observation has now been made that aromatic sulfonic acid chloramides, in particular p-toluenesulfochloramide (Chem. Centr. 1905, vol. I, page lolo), whose chlorine atom shows reactions similar to that of the chlorine atom of hypochlorites, enable new technical successes.

Die Beständigkeit genannter Körper, insbesondere - als N atronsalze, auch in heißen bis kochenden wässerigen Lösungen, sowie die Geruchlosigkeit gestätten eineAnwendung bei höheren Temperaturen.The stability of the named bodies, especially - as n attron salts, also in hot to boiling aqueous solutions, as well as the odorlessness an application at higher temperatures.

Selbstredend können die tierischen Fasern oder daraus gefertigte Textilgebilde auch bereits voroxydiert (chloriert) sein. Der Chlorgehalt des p-Toluolsulfosäurechloramids ist als »aktives Chlor« mobilisierbar und entspricht rund 25 Prozent aktivem Chlor.Of course, the animal fibers or textile structures made from them can be used also be pre-oxidized (chlorinated). The chlorine content of p-toluenesulfonic acid chloramide can be mobilized as "active chlorine" and corresponds to around 25 percent active chlorine.

Wegen der Geruchlosigkeitwe1den die Arbeiter nicht belästigt. Die Möglichkeit, bei höheren Temperaturen zu arbeiten, erlaubt ein völliges Durchoxyd'ieren bei Garnen und Stücken. Die Gewichtsabnahme, die bisher et%va 1o Prozent betrug, ist ganz minimal.Because of the odorlessness, the workers are not bothered. the The possibility of working at higher temperatures allows complete oxidation for yarns and pieces. The weight loss, which so far was about 1o percent, is quite minimal.

Die Filzfähigkeit der Fasern bleibt weitgehend erhalten, während sie bisher stark verrnindert \vurde. Feine Tierhaare insbesonders verlieren nicht an Festigkeit.The felting ability of the fibers is largely retained while they are has been greatly reduced so far. Fine animal hair in particular does not lose it Strength.

Sind den tierischen Textilgebilden Seide, Kunstseide oder Baumwolle beigemischt, -so bleiben dieseBeimengungen erhalten, während z. B. Seide bei Chlorkalk- oder Chlorbehandlung zerstört wird.Are the animal textiles silk, rayon or cotton admixed, these admixtures are retained, while z. B. silk for chlorinated lime or chlorine treatment is destroyed.

Beispiele. I. 5o kg Wollkammzug (Crossbred) werden in einem Apparat mit kreisender Flotte mit einer Lösung von 1o kg des Natriumsalzes des p-Toluo-lsulfochloramids in 8oo 1 Wasser von 6o° C etwa T Stunde behandelt und gespült.Examples. I. 50 kg of wool top (Crossbred) are in one apparatus with a rotating liquor with a solution of 10 kg of the sodium salt of p-toluene-isulfochloramide Treated and rinsed in 8oo 1 water at 60 ° C for about 1 hour.

IL 5o kg Kammzug werden zunächst in bekannter Weise mit 15 Prozent Chlorkalk oxydiert und alsdann wie in Beispiel I weiterbehandelt.IL 50 kg top draw is initially in a known manner with 15 percent Chlorinated lime is oxidized and then treated further as in Example I.
