Zusatz zum Zusatzpatent 588Addition to additional patent 588
Patentiert im Deutschen Reiche vom 18. Oktober 1930 ab Das Hauptpatent 582 239 hat angefangen am 17. März 1929.Patented in the German Empire on October 18, 1930 The main patent 582 239 started on March 17, 1929.
Gegenstand des Patents 582 239 ist ein Verfahren zum Bleichen von Bastfasern, insbesondere Leinen, Hanf u. dgl., unter Verwendung von Superoxyd- und Hypochloritbädern, welches dadurch gekennzeichnet ist, daß die Rohfaser einer abwechselnden Behandlung mit Wasserstoffsuperoxyd- und Chlorbädern in der Reihenfolge unterworfen wird: Superoxyd, Chlor (sauer), Zwischenwaschurag durch Brühen mit Sodalösung, Chlor (alkalisch bis neutral), Superoxyd. Gemäß dem Patent 588 872 hat sich ergeben, daß man die erste und letzte Stufe des Verfahrens vorteilhaft abändert, wenn die Aufgabe vorlieigt, die Ware statt auf Vollweiß zunächst nur auf eine niedrigere Bleichstufe (Viertel- bis etwa Halbweiß) zu bringen, aus dieser Ware aber mit Sicherheit die Strohteile zu entfernen. Diese Abänderung besteht darin, daß man an Stelle der ersten Superoxydbehandlung die Rohfasern zuerst einer Beuchung unterwirft, d.h. einer etwa 2- bis 3stündigen Kochung in Sodalösung (4 bis 6o/o calc. Soda, auf das Rohgewicht der Ware bezogen), und daß man dann die Ware nach dem Auswaschen der Koehlauge in das der zweiten Verfahrensstufe des Hauptpatents entsprechende saure Chlorbad einbringt, worauf das Verfahren weiter, wie im Hauptpatent beschrieben, bis einschließlich der vierten Stufe seinen Fortgang nimmt, wobei die fünfte Stufe in Fortfall kommen kann.The subject of patent 582 239 is a process for bleaching bast fibers, in particular linen, hemp and the like, using superoxide and hypochlorite baths, which is characterized in that the crude fiber is subjected to alternating treatment with hydrogen peroxide and chlorine baths in the sequence becomes: superoxide, chlorine (acidic), intermediate washing by scalding with soda solution, chlorine (alkaline to neutral), superoxide. According to the patent 588 872 it has been found that the first and last stage of the process are advantageously modified when the task at hand is to first bring the goods to a lower bleach level (quarter to about half white) from this product instead of full white but with certainty to remove the straw parts. This modification consists in that, instead of the first superoxide treatment, the raw fibers are first subjected to moistening, ie boiling in soda solution for about 2 to 3 hours (4 to 6o / o calc. Soda, based on the raw weight of the goods) Then, after washing out the Koehlauge, introduces the acidic chlorine bath corresponding to the second process stage of the main patent, whereupon the process continues, as described in the main patent, up to and including the fourth stage, whereby the fifth stage can be omitted.
Es ist nun weiterhin gefunden worden, daß man die erste Stufe des Verfahreins in manchen Fällen dadurch vorteilhaft vereinfachen kann, daß man die Ware, statt sie in einer kochenden Sodalösung zu beuchen, lediglich mit Hilfe einer warmen Alkalilösung einweicht, indem man die letztere bei Temperaturen zwischen 60 und 900 auf die Ware einwirken läßt und darauf während einiger Stunden, z. B. über Nacht, die Ware in der Lösung ohne weitere Wärmezufuhr beläßt. Hierfür sind beispielsweise Sodalösungen mit etwa 4 bis 6 0/0 calc. Soda, auf das Rohgewicht der Ware bezogen, geeignet, die gegebenenfalls auch Ätzalkali enthalten können. Nach dieser Einweichung wird die Ware kurz gewaschen und nunmehr gemäß den weiteren Verfahrensstufen nach Patent 588 872 der Chlorbleiche in saurer Lösung usw. weiterbehandelt. It has now also been found that the first stage of the procedure can be simplified in some cases by simply soaking the goods in a warm alkali solution instead of soaking them in a boiling soda solution by soaking the latter at temperatures between 60 and 90 0 can act on the goods and then for a few hours, z. B. overnight, the goods are left in the solution without additional heat supply. For example, soda solutions with about 4 to 6% calc. Soda, based on the gross weight of the goods, is suitable, which may also contain caustic alkali. After this soaking process, the goods are briefly washed and then further treated in accordance with the further process steps according to patent 588 872 of chlorine bleaching in an acidic solution, etc.

Der technische Vorteil der neuen Abänderung des Verfahrens liegt darin, daß bei unvermindert restloser Entfernung der Strohteile (Schaben) die Gewichts--und Festigkeit^.· Verluste der Ware noch eine merkliche V^ minderung erfahren; dieses Ergebnis ist im· ■wesentlichen auf die Unterlassung der Beuchung zurückzuführen.The technical advantage of the new amendment to the procedure is that it remains unchanged complete removal of the straw parts (scraping) the weight and strength ^. · Losses of the commodity still experience a noticeable reduction; this result is in ■ can be largely attributed to the omission of the booking.
