Description

Bleichen von Borsten. Es ist bekannt, Borsten, wie insbesondere Schweinsborsten, mit Hilfe von Superoxyden zu bleichen.Bristle bleaching. It is known to use bristles, especially pig bristles, to bleach with the help of super oxides.

Es wurde nun gefunden, daß sich nicht nur die bisher übliche Bleichdauer von 24 bis 48 Stunden auf etwa 8 bis 12 Stunden vermindern, sondern auch ein höheres Weiß und ein geringerer Superoxydverbrauch erreichen l.äßt, wenn man diesem bekannten Bleichverfahren eine etwa i'2stündige Behandlung der Borsten mit z bis q. Prozent wirksamem Chlor (berechnet auf das Rohmaterial) in schwach saurer Lösung vorausgehen l,äßt. Es werden Borsten von hohem Glanz und vorzüglicher Biegsamkeit gewonnen werden, die einer besonderen Nachbehandlung mit Ölen irgendwelcher Art nicht mehr bedürfen; auch ein Seifen nach der Chlorbehandlung erübrigt sich. Beispiel.It has now been found that not only the bleaching time that has been customary up to now is used from 24 to 48 hours to about 8 to 12 hours, but also a higher one White and a lower consumption of superoxide can be achieved if one is familiar with this Bleaching process involves treating the bristles with z to q for about 12 hours. percent effective chlorine (calculated on the raw material) in weakly acidic solution leaves. Bristles of high gloss and excellent flexibility will be obtained, which no longer require special post-treatment with oils of any kind; soaping after chlorine treatment is also unnecessary. Example.

ioo kg Borsten werden nach kurzem Waschen zur Entfernung grober Verunreinigungen mit einer freie unterchlorige Säure enthaltenden Chlorkalk- oder Natriumhypochloritlösung oder mit Chlorwasserlösung von einem Gesamtgehalt an wirksamem Chlor, entsprechend z bis q. Prozent bezogen auf das Rohwaregewicht, bei Zimmertemperatur etwa 1/2 Stunde lang vorbehandelt. Es kann hierbei die Hypochloritlösung entweder angesäuert zugegeben werden, oder aber die Chlorlauge im Bleichbehälter mit Säure bis zur schwach sauren Reaktion versetzt werden. Man bleicht dann ohne zu waschen mit einprozentiger Natriumsuperoxyd- oder schwach ammoniakalisch:er Wasserstoffsuperoxydlösung ohne irgendwelche Zusätze 8 bis I a Stunden nach, spült und trocknet wie üblich.100 kg of bristles are washed for a short time to remove coarse soiling with a chlorinated lime or sodium hypochlorite solution containing free hypochlorous acid or with a chlorine water solution with a total content of effective chlorine, accordingly z to q. Percentage based on the weight of the raw material, about 1/2 hour at room temperature long pretreated. The hypochlorite solution can either be added acidified or the chlorine liquor in the bleaching tank with acid up to weakly acidic Reaction. It is then bleached without washing with one percent sodium superoxide. or weakly ammoniacal: he hydrogen peroxide solution without any additives 8 to 1 a hours after, rinses and dries as usual.
