Description
Verfahren zum Bleichen von Fasern, Garnen, Geweben, Gewirken, Textilwaren u. dgl. aus natürlichen oder synthetischen Fasern Zusatz zur Patentanmeldung D 20 836 IVa / 23 e (Auslegeschrift 1018 181) Die Patentanmeldung D 20836 IVa/23e (deutsche Auslegeschrift 1018181) beschreibt ein Verfahren zum Bleichen von Fasern, Garnen, Geweben, Gewirken, Textilwaren u. dgl. aus natürlichen oder synthetischen Faserstoffen mit Peroxyde enthaltenden wäßrigen Lösungen oder Suspensionen in Gegenwart von organischen Nitrilen. Vorzugsweise arbeitet man so, daß je Mol peroxydischen Sauerstoffs etwa eine Nitrilgruppe zugegen ist. Die Behandlung kann bei Temperaturen zwischen 50 und 80°C durchgeführt werden. Die Flotte kann die üblichen Stabilisatoren, Netzmittel und/oder Faserschutzmittel enthalten.Process for bleaching fibers, yarns, woven, knitted fabrics, textile goods and the like made from natural or synthetic fibers Addition to patent application D 20 836 IVa / 23 e (Auslegeschrift 1018 181) Patent application D 20836 IVa / 23e (German Auslegeschrift 1018181) describes a process for bleaching fibers, yarns, woven, knitted fabrics, textile goods and the like from natural or synthetic fiber materials with aqueous solutions or suspensions containing peroxides in the presence of organic nitriles. It is preferred to operate in such a way that about one nitrile group is present per mole of peroxidic oxygen. The treatment can be carried out at temperatures between 50 and 80 ° C. The liquor can contain the usual stabilizers, wetting agents and / or fiber protection agents.
Die organischen Nitrile bewirken bei Anwesenheit von Peroxyden in Wasch- und Bleichbädern eine Steigerung der Bleichwirkung, die über die normale hinausgeht. Man kann also in Gegenwart dieser Nitrile eine Bleichwirkung erhalten, die man ohne die erfindungsgemäßen Zusätze unter sonst gleichen Bedingungen erst bei höheren Temperaturen erhält.The organic nitriles cause in the presence of peroxides in Washing and bleaching baths increase the bleaching effect beyond the normal goes out. So you can get a bleaching effect in the presence of these nitriles, which can only be obtained without the additives according to the invention under otherwise identical conditions at higher temperatures.
Es wurde nun gefunden, daß eine wesentliche Verbesserung der Bleichwirkung erzielt wird, wenn man als Zusatz acylierte Cyanhydrine, für sich oder im Gemisch miteinander oder mit den in der Patentanmeldung D 20836 IVa/23e (deutsche Auslegeschrift 1018181) genannten Stoffen, verwendet. Die Verwendung dieser Stoffe macht es möglich, eine vollständigere Bleiche in kürzerer Zeit bzw. bei tieferer Temperatur zu erhalten als bei Verwendung der in der Hauptpatentanmeldung erwähnten Stoffe. In vielen Fällen genügt auch schon ein geringerer Zusatz.It has now been found that there is a substantial improvement in the bleaching effect is achieved if you add acylated cyanohydrins, alone or in a mixture with each other or with the in the patent application D 20836 IVa / 23e (German Auslegeschrift 1018181) is used. The use of these substances makes it possible to obtain a more complete bleaching in a shorter time or at a lower temperature than when using the substances mentioned in the main patent application. In many cases A minor addition is sufficient.
Verbindungen gemäß der Erfindung sind beispielsweise Acetoxy-propionsäurenitril Acetoxy-isobuttersäurenitril Wie bei dem Verfahren der Hauptpatentanmeldung empfiehlt es sich, so zu arbeiten, daß in der Flotte je Mol peroxydischen Sauerstoffs etwa eine Nitrilgruppe zugegen ist. Die Behandlung kann bei Temperaturen zwischen 50 und 80°C durchgeführt werden. Die Flotte kann ebenfalls die üblichen Stabilisatoren, Netzmittel und/oder Faserschutzmittel enthalten. Es wurde ferner gefunden, daß es zweckmäßig ist, die Behandlung in einer alkalischen Flotte, d. h. bei pH-Werten über 7, durchzuführen. Diese pH-Werte können in üblicher Weise eingestellt werden.Compounds according to the invention are, for example, acetoxypropionic acid nitrile Acetoxy-isobutyric acid nitrile As in the process of the main patent application, it is advisable to work in such a way that about one nitrile group is present in the liquor per mole of peroxidic oxygen. The treatment can be carried out at temperatures between 50 and 80 ° C. The liquor can also contain the usual stabilizers, wetting agents and / or fiber protection agents. It has also been found that it is expedient to carry out the treatment in an alkaline liquor, ie at pH values above 7. These pH values can be adjusted in the usual way.
Einige der erfindungsgemäßen Nitrilverbindungen sind in trockenem Zustand im Gemisch mit trockenen peroxydischen Verbindungen, gegebenenfalls auch unter Zusatz weiterer Bestandteile von Waschmitteln, gut lagerfähig.Some of the nitrile compounds according to the invention are in dry conditions Condition in a mixture with dry peroxidic compounds, possibly also with the addition of other detergent ingredients, can be stored well.
Beispiel 1 Proben eines Baumwollgewebes, das nach den Vorschriften der Eidgenössischen Materialprüfungs-und Versuchsanstalt in St. Gallen mit Immedialschwarz gefärbt worden war, wurden bei 60°C 1 Stunde in Bleichbädern behandelt, dann gespült und getrocknet. Das Bleichbad a) enthält je Liter 1 ccm Natronwasserglas, 38° B6; 0,1 g Magnesiumsulfat, 0,6 ccm Natronlauge, 38° B6; 10 ccm Wasserstoffperoxyd, 35gewichtsprozentig.Example 1 Samples of a cotton fabric, which according to the regulations of the Federal Materials Testing and Research Institute in St. Gallen with Immedialschwarz had been dyed were treated in bleach baths at 60 ° C. for 1 hour, then rinsed and dried. The bleach bath a) contains 1 ccm sodium water glass, 38 ° B6 per liter; 0.1 g magnesium sulfate, 0.6 ccm sodium hydroxide solution, 38 ° B6; 10 cc hydrogen peroxide, 35 weight percent.
Das Bleichbad b) hatte dieselbe Zusammensetzung, nur enthielt es zusätzlich
je Liter 2 g Acetoxy-propionsäurenitril. Nach der Behandlung wurde der Weißgrad
der Proben mit dem Zeiss-»Elrepho«-Gerät bestimmt.
Die Flotte c) hatte dieselbe Zusammensetzung wie die Flotte a), nur enthielt sie zusätzlich je Liter Acetoxy-propionsäurenitril.The liquor c) had the same composition as the liquor a), only it also contained acetoxypropionic acid nitrile per liter.
Mit diesen drei Flotten wurden die Proben je dreimal 15 Minuten bei
60°C gewaschen und dann getrocknet. Nach der Behandlung wurden die folgenden Weißgehalte
mit dem »Elrepho<c-Zeiss-Gerät festgestellt
