Description

Verfahren zur Behandlung pflanzlicher Fasern mit alkalischen, oxydierenden und reduzierenden Mitteln. Die Erfindung betrifft ein Verfahren zur Behandlung pflanzlicher Fasern mit alkalischen, oxydierenden oder reduzierenden Mitteln, und es kommt dabei darauf an, daß die Behandlung der pflanzlichen Fasern mit diesen Mitteln in Gegenwart solcher Mengen von gelösten und in Lösung bleibenden natürlichen oder künstlichen Gerbstoffen, gerbstoffähnlichen Stoffen bzw. gerbstoffhaltigen Flüssigkeiten, wie gebrauchten Gerbbrühen, erfolgt, die zur vollständigen: Reduzierung der gegebenenfalls angewandten Oxydationsmittel nicht ausreichen. Es hat sich gezeigt, daß die pflanzlichen Fasern bei Behandlung in Gegenwart derartiger Lösungen weitgehend geschont und geschützt werden.Process for treating vegetable fibers with alkaline, oxidizing agents and reducing agents. The invention relates to a method for treating plants Fibers with alkaline, oxidizing or reducing agents, and it comes with it on that the treatment of the vegetable fibers with these agents in the presence such amounts of dissolved and remaining in solution natural or artificial Tannins, substances similar to tannins or liquids containing tannins, such as used tanning liquor, which takes place to complete: Reduction of where appropriate The oxidizing agent used is not sufficient. It has been shown that the vegetable Fibers largely spared and protected when treated in the presence of such solutions will.

Der Zusatz von Gerbstoffen zur pflanzlichen Faser ist zwar an sich bekannt; bei den bekannten Verfahren handelt es sich aber einerseits nicht um die Erreichung eines Faserschutzes gegenüber der Einwirkung solcher `dittel, die aqdernfalls die Faser schädigen würden, andererseits erfolgt dort der Zusatz der Gerbstoffe auch unter Bedingungen, die einen solchen Faserschutz gar nicht ermöglichen würden. Denn im einen Falle sollen die Gerbstoffe mit gleichzeitig zur Anwendung kommenden Proteinen eine Niederschlagsbildung in alkalischer Lösung bewirken, wodurch ihre Wirksamkeit als Faserschutzmittel natürlich aufgehoben wird. In einem andern bekannten Falle soll durch Behandlung finit Gerbstoffen die Bildung unlöslicher Chromniederschläge auf der Faser verursacht werden, die als Beize beim Färben dienen sollen. Bedingung ist dabei also, daß die Gerbsäure in derartig großen Mengen angewandt wird; daß das gesamte zugesetzte Bichromat zu Chromoxyd reduziert und in unlöslicher Form niedergeschlagen wird, derart, daß hier das Biehromat überhaupt nicht oxydierend und also auch nicht faserschädigend zu wirken vermag. Im Gegensatz dazu kommt es bei der vorliegenden Erfindung, soweit sie das Oxydationsverfahren betrifft, natürlich darauf an, daß die zugesetzten Gerbstoffe zur vollständigen Reduzierung der Oxydationsmittel nicht ausreichen, diese vielmehr ihre oxydierende Wirkung noch auszuüben vermögen. Dabei wirken dann die vorhandenen Gerbstoffe faserschützend. Es wird demgemäß in diesem Falle nach der Erfindung mit verhältnismäßig geringen Mengen Gerbstofflösung gearbeitet, die nur einen sehr geringen Teil des Oxydationsmittels zu reduzieren vermögen. Wohl werden die Gerbstoffe hierbei oxydiert, aber auch in dieser oxydierten Form wirken sie noch faserschützend gegen das in erheblichem Überschuß angewandte Oxydationsmittel.The addition of tannins to the vegetable fiber is in itself known; in the known methods, on the one hand, it is not the Achievement of fiber protection against the effects of such `agents, which aqdernfall would damage the fiber, on the other hand, there is the addition of the tannins even under conditions that would not allow such fiber protection at all. Because in one case the tannins should be used at the same time Proteins cause a precipitate in alkaline solution, thereby reducing their Effectiveness as a fiber protection agent is naturally canceled. In another well-known one Trap is said to cause the formation of insoluble chromium precipitates by treating finite tannins on the fiber to be used as a stain in dyeing. condition What is involved is that tannic acid is used in such large quantities; that all of the added bichromate is reduced to chromium oxide and in insoluble form is knocked down in such a way that the Biehromat is not oxidizing at all and therefore not able to damage the fibers. In contrast, it comes in the present invention as far as the oxidation process is concerned, of course on that the added tannins to the complete reduction of the oxidizing agent are not sufficient for these to be able to exert their oxidizing effect. The existing tannins then have a fiber-protecting effect. It is accordingly used in this case according to the invention with relatively small amounts of tanning solution worked to reduce only a very small part of the oxidant capital. The tannins are oxidized here, but also oxidized in this In form, they still have a fiber-protecting effect against that which is used in considerable excess Oxidizing agent.

Die Erfindung kann Anwendung finden nicht nur beim Waschen und Bleichen, sondern überhaupt bei solchen Verfahren, bei denen die Faser mit Oxydations- oder Reduktionsmitteln sowie mit Alkalien in Berührung kommt. Erwähnt seien die Verfahren, bei denen Chromsäureverbindungen, Chlorate, Persulfate, Superoxyde bzw. Reduktionsmittel, wie Hydrosulfite, Sulfite usw., zur Verwendung kommen, z. B. in der Anilinschwarzfärberei, beim Ätzen von Farbstoffen, beim Reservieren u. dgl.The invention can be used not only in washing and bleaching, but at all in those processes in which the fiber with oxidation or Reducing agents as well as comes into contact with alkalis. Mentioned be the processes in which chromic acid compounds, chlorates, persulfates, superoxides or reducing agents such as hydrosulfites, sulfites, etc., are used, e.g. B. in aniline black dyeing, the etching of dyes, when reserving u. like

Ausführungsbeispiele. i. Bei der Entwicklung von Anilinschwarz auf der Faser setzt man zu deren Schonung io Prozent des angewandten Natriumchlorats an Quebrachogerbstoff zu und verfährt im übrigen nach eineni der bekannten Verfahren. Auch bei der Nachchromierung empfiehlt sich ein Zusatz von 5 Prozent des Bichromats an Gerbstoff.Embodiments. i. In the development of aniline black on 10 percent of the sodium chlorate used is added to the fibers to protect them of quebracho tanning agent and otherwise proceeds according to one of the known processes. An addition of 5 percent of the bichromate is also recommended for post-chrome plating of tannin.

Viele Gerbstoffe scheinen sogar katalytisch zu wirken und die Entwicklung des Farbstoffes zu beschleunigen.Many tannins even seem to act catalytically and develop to accelerate the dye.

z. Behandelt man Baumwolle bei 8o° etwa eine halbe Stünde lang mit o,6prozentiger Natronlauge, so geht die Reißfestigkeit, gemessen am Schopperschen Apparat, von 1535 auf 14.8o zurück. Setzt man aber bei der Behandlung mit Natronlauge 1o ccm Gerbereiablauge hinzu, so beträgt die Reißfestigkeit nach gleicher Behandlungsweise 15o5.z. Treat cotton at 80 ° for about half an hour 0.6 percent sodium hydroxide solution, this is the tensile strength, measured on Schoppers Apparatus, from 1535 back to 14.8o. But if you use caustic soda for treatment 1o ccm of tannery liquor is added, the tensile strength is the same after the same treatment 15o5.

3. Behandelt man Baumwolle etwa eine halbe Stunde lang bei 6o° mit o,5 Prozent Schwefelnatrium, so geht die Reißfestigkeit vors 152o auf 140 zurück. Setzt man aber vor dieser Behandlung o,5 Prozent eines künstlichen Gerbstoffs, wie Neradol ND (Kondensationsprodukt von aromatischen Sulfosäuren mit Formaldehyd), hinzu, so beträgt die Reißfestigkeit nach im übrigen gleichartiger Behandlung 1570; sie ist also sogar höher als im unbehandelten Material.3. If cotton is treated with 0.5 percent sodium sulphide at 60 ° for about half an hour, the tensile strength drops to 140 before 150 °. If, however, 0.5 percent of an artificial tanning agent such as Neradol ND (condensation product of aromatic sulfonic acids with formaldehyde) is added before this treatment, the tear strength after otherwise similar treatment is 1570; so it is even higher than in the untreated material.

Kocht man Baumwolle drei Stunden lang mit Natriumperborat in der Weise, daß man zunächst o,5 Prozent Natriumperborat zusetzt, nach einstündiger Behandlung abkühlt und weitere o,5 Prozent Natriumperborat hinzufügt und nach der zweiten Stunde entsprechend verfährt, so geht die Reißfestigkeit der Baumwolle durch diese Behandlung- von 159o auf I24.0 zurück. Beim Zusatz von nur o,5 Prozent Ouebrachogerbstoff vor Beginn der Kochung erhöht sich hingegen die Reißfestigkeit auf 162o. Wenn man aber die Menge des zugesetzten Gerbstoffs auf i Prozent vermehrt, so ist die Reißfestigkeit nach der Behandlung mit Natriumperborat geringer als im vorigen Falle und beträgt nur 152o.If cotton is boiled for three hours with sodium perborate in the manner that you first add 0.5 percent sodium perborate, after one hour of treatment cools and another 0.5 percent sodium perborate is added and after the second hour proceeds accordingly, the tensile strength of the cotton goes through this treatment- from 159o back to I24.0. With the addition of only 0.5 percent ouebracho tanning agent At the beginning of boiling, however, the tear strength increases to 162o. But if you can If the amount of tanning agent added is increased to 1 percent, it is the tear strength after treatment with sodium perborate is lower than in the previous case and is only 152o.
