Description
Verfahren zur Behandlung von tierischen Fasern Es ist bereits vorgeschlagen worden, verunreinigende Fremdkörper, wie pflanzliche und mineralische Stoffe, Schmutz, Fett und Seifen, aus roher, nicht enfischweißter Wolle durch Eintauchen in kalte Schwefelsäure zu entfernen.Method of treating animal fibers It has already been proposed contaminating foreign bodies such as vegetable and mineral substances, dirt, Fat and soaps, made from raw, not enfish-white wool by dipping in cold Remove sulfuric acid.
Es ist auch bekannt, daß man Wo71e mit verdünnter Schwefelsäure ohne Beschädigung erhitzen kann, und daß man Wolle bleichen kann, wenn, man sie mit Schwefelsäure zusammen mit üblichen Bleichmitteln behandelt.It is also known that one can work with dilute sulfuric acid without Damage can heat up, and that wool can be bleached if you treat it with sulfuric acid treated together with common bleaches.
Gemäß der Erfindung werden tierische Fasern, wie Wolle, gebleicht oder entfärbt, wenn man sie -der Einwirkung einer Lösung von Schwefelsäure von etwa 5 Volumenpr-,zent, vorzugsweise bei gewöhnlichem Atmosphärendruck, einer Temperatur von etwa 70° C während einer kurzen Zeitdauer, etwa i o Minuten, behandelt.According to the invention, animal fibers such as wool are bleached or discolored if you -the action of a solution of sulfuric acid of about 5 percent by volume, preferably at ordinary atmospheric pressure, of a temperature of about 70 ° C for a short period of time, about 10 minutes.
Durch diese Behandlung erfahren mit der tierischen Faser etwa gemischte Pflanzen: fasern keine erhebliche Schädigung.Through this treatment experienced about mixed with the animal fiber Plants: fibers do not cause significant damage.
Fasern, die nach diesem Verfahren behandelt worden sind, können gewünschtenfalls einer weiteren Bleichung mit anderen Bleichmitteln unterworfen werden.Fibers treated by this process can, if desired be subjected to further bleaching with other bleaching agents.
Beispielsweise kann man das Gut zunächst in der beschriebenen: Weise behandeln, und wenn dieses Verfahren beendet isst, können andere Bleichmittel, z. B. Natriumhydrosulfit, zu demselben Bade zugesetzt werden. Man kann auch das Gut zuerst in die Lösung von Schwefelsäure eintauchen und in der beschriebenen.
