Description
Gegenstand des Patents 582 239 ist ein Verfahren zum Bleichen von Bastfasern, insbesondere Leinen, Hanf u. dgl., in Form von Garnen und Geweben wie auch von Roh-S fasern unter Verwendung von Superoxyd- und Hypochloritbädern, das dadurch gekennzeichnet, ist, daß die Rohfaser einer abwechselnden Behandlung mit Wasserstoffsuperoxyd- und Chlorbädern in der Reihenfolge unterworfen wird: Superoxyd, Chlor (sauer) mit einer Azidität entsprechend pn < 5, Zwischenwaschung durch Brühen mit Sodalösung, Chlor (alkalisch bis neutral), Superoxyd.The subject of patent 582 239 is a Process for bleaching bast fibers, in particular linen, hemp and the like, in the form of Yarns and fabrics as well as raw S fibers using superoxide and hypochlorite baths, which is characterized in that the crude fiber is an alternating Treatment with hydrogen peroxide and chlorine baths is subjected in the order: superoxide, chlorine (acidic) with an acidity corresponding to pn <5, intermediate washing by scalding with Soda solution, chlorine (alkaline to neutral), superoxide.
In weiterer Ausarbeitung der Erfindung hat sich ergeben, daß man die erste und letzte Stufe des Verfahrens vorteilhaft abändert, wenn die Aufgäbe vorliegt, die Ware statt auf Vollweiß nur auf eine niedrigere Bleichstufe, Viertel- bis etwa Halbweiß, zu bringen, aus dieser Ware aber mit Sicherheit die Strohteile zu entfernen. Man unterwirft an Stelle der ersten Superoxydbehandlung die Rohware zuerst - einer Bauchung, d. h.In a further elaboration of the invention it has been found that the first and The last stage of the procedure advantageously modifies the goods when the task is present instead of full white only to a lower bleach level, quarter to about half white bring, but with certainty to remove the straw parts from this product. One submits Instead of the first superoxide treatment, the raw material first - a bulge, d. H.
einer etwa 1- bis 3stündigen Kochung in Sodalösung (2 bis 6 °/o calcinierter Soda, auf das Rohgewicht der Ware bezogen). Die Anwendung von Druck ist hierbei nicht notwendig. Die gebauchte Ware bringt man dann nachboiling for about 1 to 3 hours in soda solution (2 to 6 per cent. of calcined soda, on the Gross weight of the goods related). The application of pressure is not necessary here. The booked goods are then brought in
dem Auswaschen der Kochlauge in das der zweiten Verfahrensstufe des Hauptpatents entsprechende Chlorbad mit einer Azidität entsprechend pn < 5, worauf das Verfahren weiter wie gemäß Hauptpatent bis einschließlich der vierten Stufe seinen Fortgang nimmt. Die fünfte Stufe dagegen kann in Fortfall kommen. Durch die Neuerung wird einem Benutzer des Verfahrens, der über Bäuchvorrichtungen verfügt, der Vorteil verschafft, diese zur Ausübung des Verfahrens zu benutzen. Man erhält einen strohfreien,' in der Farbtönung etwa einem Viertel- bis Halbweiß entsprechenden Faden von gegenüber dem Rohfaden unveränderter Reißfestigkeit,: der sich sehr gut und gleichmäßig färben läßt.washing out the cooking liquor in the second process stage of the main patent corresponding chlorine bath with an acidity corresponding to pn <5, whereupon the process continues as in the main patent up to and including the fourth stage takes. The fifth stage, on the other hand, can be omitted. The innovation will a user of the method who has abdominal devices who provides an advantage, to use them to carry out the procedure. You get a straw-free, 'about a quarter to in color Semi-white thread of the same tensile strength as the raw thread: which can be colored very well and evenly.
Falls eine Färbung der Ware nicht in Betracht kommt, kann man, nachdem durch die ersten drei Stufen des oben beschriebenen Verfahrens die durchgreifende Grundbleiche erzielt ist, die die störenden Strohteile und die Hauptmenge des Lignins beseitigt, eine so behandelte Partie des Gutes gegebenenfalls auch beliebig weiter bis zu Vollweiß bleichen. Für die.se Ergänzungsbleiche kann man verschiedene, an sich für die Bastfaserbleiche bekannte Verfahren einschlagen. Man kann z. B. als fünfte Stufe nochmals eineIf the goods are not colored, you can go through the the first three stages of the process described above achieve the thorough base bleaching that eliminates the annoying straw parts and most of the lignin, one like that If necessary, bleach the treated part of the goods any further until it is completely white. For die.se can supplement bleach various methods known per se for bleaching bast fibers are used. Man can e.g. B. again as a fifth stage

kurze Brühung mit verdünnter Sodalösung anschließen und dann die Ware wenige Tage aushängen oder eine schwache Superoxydoder eine schwache Hypochloritbleiche oder schließlich auch eine Kombination von "beiden folgen lassen.Follow up with a short brewing with diluted soda solution and then the goods for a few days hang out or a weak superoxide or a weak hypochlorite bleach or Finally, a combination of "both follow.
Bleichverfahren für Cellulose, bei denen auf ein Hypochloritbad von schwach saurer Reaktion eine alkalische Auswaschung undBleaching process for cellulose, which involves a hypochlorite bath of weakly acidic Reaction an alkaline washout and
ίο ein Hypochloritbad von alkalischer Reaktion· folgen, sind aus der Zellstoffverarbeitung, insbesondere für die Zwecke der Papiergewinnung, bekannt. Hiervon unterscheidet sich das Verfahren gemäß der Erfindung sowohl bezüglich des anzuwendenden Mittels wie bezüglich des angestrebten Zwecks. Eine Azidität entsprechend pn < 5, wie sie z. B. erhalten wird, wenn eine Hypochloritlösung, mit ι bis 8 g wirksamem Chlor im Liter mit einem Zusatz von Salzsäure entsprechend 8 bis 15g H Cl im Liter versehen wird, ist für die Durchführung der Bleiche von Zellstoffen irgendwelcher Herkunft bisher niemals vorgeschlagen worden. Für Anwendung einer so hohen Azidität bestand bisher keine Veranlassung, da schon wesentlich schwächere Säuregrade für die angestrebten Zwecke der Bleiche von Sulntcellulose, Hadern u. dgl. völlig ausreichten. In den genannten Fällen handelt es sich nicht um den besonderen Zweck, die für Bastfasern charakteristischen · strohigen Begleitbestandteile der Cellulose, die bisher eine glatte Durchführung der Chlorbleiche bei Bastfasern vollkommen verhinderten, durch Chloreinwirkung in saurer Lösung in alkalilösliche Form überzuführen, ohne daß eine Schädigung der Faserfestigkeit eintritt.ίο a hypochlorite bath of alkaline reaction are from pulp processing, in particular for the purposes of paper production, known. The method according to the invention differs from this both with regard to the means to be used as well as with regard to the intended purpose. An acidity corresponding to pn <5, as z. B. is obtained when a hypochlorite solution, with ι to 8 g of effective chlorine per liter an addition of hydrochloric acid corresponding to 8 to 15g H Cl per liter is provided for the implementation of the bleaching of cellulose of any origin never before has been proposed. To date, there has been none for the use of such a high acidity The reason for this is that the degree of acidity is much weaker for the intended purposes of the Bleaching of sulnt cellulose, rag and the like were completely sufficient. In the cases mentioned it is not about the special purpose characteristic of bast fibers straw-like constituents of cellulose, which have so far been a smooth implementation of the Chlorine bleaching in bast fibers was completely prevented by the action of chlorine in acidic Convert the solution into an alkali-soluble form without damaging the fiber strength entry.
