Description

Verfahren zum Bleichen von Haaren oder Federn Man hat bisher aktiven Sauerstoff zum Bleichen in der Hauptsache in Form von Wasserstoffsuperoxydlösungenverwendet. Eine Ausnahme hiervon macht die Bleiche von Seifen und ölen, die mit Persulfat und Benzoylsuperoxyd vorgenommen wird. Bleichen mit Perborat oder Percarbonat oder ähnlichen -Verbindungen sind praktisch Wasserstoffsuperoxydbleichen, da diese Verbindungen Wasserstoffsuperoxyd abspalten. Auch sind zu Wasch- und Bleichzwecken Mischungen vorgeschlagen worden, die aus' Peroxyden und Ozoniden ungesättigter organischer Verbindungen und aus alkaliabspaltender anorganischen Peroxyden oder Perboraten bestehen. Hierbei verhalten sich die anorganischen Perborate in Berührung mit Wasser wie Wasserstoffsuperoxyd, während die Peroxyde der organischen Verbindungen ihren Sauerstoff unter Einwirkung von Alkali als Wasserstoffsuperoxyd abgeben. Als Bleichmittel ist außerdem auch Carosche Säure bekannt, die durch Umsetzen von Alkalipersulfat mit hochkonzentriertem Wasserstoffsuperoxyd entsteht. Dieselbe spaltet sich aber in der Kälte zu Schwefelsäure und Wasserstoffsuperoxyd und kommt in jenen Konzentrationen, in denen sie bisher hergestellt und beobachtet wurde, für das Bleichen von Faserstoffen nicht in Betracht, da diese hiervon angegriffen werden.Method for bleaching hair or feathers One has so far been active Oxygen for bleaching is mainly used in the form of hydrogen peroxide solutions. An exception to this is the bleaching of soaps and oils that contain persulphate and Benzoyl peroxide is made. Bleaching with perborate or percarbonate or similar -Compounds are practically hydrogen peroxide bleaching as these compounds Eliminate hydrogen peroxide. Mixtures are also used for washing and bleaching purposes it has been proposed that the 'peroxides and ozonides of unsaturated organic Compounds and from inorganic peroxides or perborates that split off alkali exist. Here, the inorganic perborates behave in contact with water like hydrogen peroxide, while the peroxides of organic compounds are theirs Release oxygen as hydrogen peroxide under the action of alkali. As a bleach Caro's acid is also known, which is produced by reacting alkali persulfate with highly concentrated hydrogen peroxide is formed. But it splits in the cold to sulfuric acid and hydrogen peroxide and comes in those concentrations in which it has so far been manufactured and observed, for the bleaching of pulps out of consideration, as they are attacked by it.

Soweit Wasserstoffsuperoxydlösungen mit Persulfat versetzt worden sind, hat man an solchen Lösungen lediglich eine gesteigerte Zersetzlichkeit beobachtet, konnte- aber daraus nicht den Schluß ziehen, daß solche Lösungen besonders kräftige Bleichwirkung ohne Schädigung der Bleichwaren zeigen würden. Würde man in diesem Fall statt Persulfate Permanganate verwenden, so würden sich dieselben mit Wasserstoffsuperoxyd unter Sauerstoffabgabe so schnell zersetzen, daß solche Mischungen zu Bleichzwecken völlig unbrauchbar wären.As far as hydrogen peroxide solutions have been mixed with persulfate only an increased decomposition has been observed in such solutions, but could not draw the conclusion from this that such solutions were particularly powerful Would show bleaching effect without damaging the bleached goods. You would in this If permanganates were used instead of persulphates, they would react with hydrogen peroxide decompose with the release of oxygen so quickly that such mixtures are used for bleaching purposes would be completely useless.

Es ist ferner bekannt, ein Gemisch von verdünntem Wasserstoffsuperoxyd und Persalzen, z. B. Perborat, zum Bleichen von Faserstoffen zu benutzen.It is also known to use a mixture of dilute hydrogen peroxide and persalts, e.g. B. perborate to use for bleaching fibers.

Es wurde nun gefunden, daß man Haare oder Federn vorteilhaft mit Mischungen aus verdünnten Wasserstoffsuperoxydlösungen und wasserlöslichen Persulfaten bleichen kann. Man hätte erwarten sollen, daß derartige Gemische sich beim Bleichen gegenseitig zersetzen oder daß eine Schädigung der Faser durch das 1?ersulfat eintreten würde. Das ist aber nicht der Fall. Vielmehr tritt eine stärkere Bleichwirkung ein als bei Verwendung der einzelnen Komponenten.It has now been found that hair or feathers can advantageously be mixed with them bleach from dilute hydrogen peroxide solutions and water-soluble persulfates can. One would have expected such mixtures to be mutually exclusive during bleaching decompose or that the fiber would be damaged by the sulfate. That's not the case. Rather, a stronger bleaching effect occurs than when using the individual components.

Um die Bleichwirkung mehr oder weniger' stark zu gestalten, kann man die Bleichlösungen mit indifferenten Flüssigkeiten, z. B. Al= kohol, versetzen. Die Bleichbäder können bei Verwendung dieser Gemische je nach Bedarf alkalisch, neutral oder sauer verwendet werden. Die Bleichwirkung solcher Gemische ist so kräftig, daß sie bereits in wenigen Stunden in der Kälte schnell und wirksam bleichen. Beispiel Gewisse Farbstoffe in den Haaren oder F6-dern lassen sich durch Wasserstoffsuperoxyd nicht oder nur sehr mangelhaft bleichen. Wendet man das Wasserstoffsuperoxyd zum Zwecke einer gesteigerten . Wirkung längere Zeit oder in stärkeren Bädern an, so wird die zu bleichende Ware angegriffen. Verwendet man dagegen ein Bleichbad von z,. B. i oö g Wasserstoffsuperoxyd (30 %ig), - 1000 g Wasser, 2o bis 309 96 %igem Alkohol -und 3o g Ammoniumpersulfat, so lassen sich mit diesem Bad bei gewöhnlicher Temperatur Federn und Haare in wenigen Stunden hell bleichen, ohne daß das Bleichgut angegriffen wird. Beschleunigt und gesteigert wird die Bleichwirkung in vielen Fällen dadurch, daß man die zu bleichende Ware während des Bleichvorganges in bekannter Weise belichtet; wobei der Bleichvorgang sowohl im Bleichbad selbst stattfinden kann als auch in der Luft, dadurch, daß man die Ware mit den angegebenen Lösungen tränkt.In order to make the bleaching effect more or less' strong, the bleaching solutions can be mixed with inert liquids, e.g. B. Al = alcohol. When using these mixtures, the bleach baths can be alkaline, neutral or acidic as required. The bleaching effect of such mixtures is so powerful that they bleach quickly and effectively in the cold in just a few hours. Example Certain dyes in the hair or hairs cannot be bleached or bleached only very poorly with hydrogen peroxide. If one turns the hydrogen peroxide for the purpose of an increased. If it works for a longer period of time or in stronger baths, the goods to be bleached will be attacked. If, on the other hand, a bleach bath of z. B. i oö g hydrogen peroxide (30%), - 1000 g water, 2o to 309 96% alcohol and 3o g ammonium persulfate, so feathers and hair can be bleached lightly with this bath at normal temperature in a few hours without the bleached material is attacked. The bleaching effect is accelerated and increased in many cases by exposing the goods to be bleached in a known manner during the bleaching process; whereby the bleaching process can take place both in the bleach bath itself and in the air, by soaking the goods with the specified solutions.
