Description

Verfahren zur Dehydrierung und Oxydation von tierischen Fasern Es ist bekannt, daB durch- Einwirkung von Metallsalzen der Nitrosodisulfonsäure auf Verbindungen mit aromatisch. geb2trden.en Hydroxylgruppen Chinone entstehen.Process for the dehydration and oxidation of animal fibers Es it is known that the action of metal salts of nitrosodisulfonic acid Compounds with aromatic. Quinones formed by the hydroxyl groups formed.

Es wurde nun gefunden, daB sich diese Reaktion auch auf tierische Fasern, wie Wolle, Seide und Kollagen, anwenden läBt, wodurch diese Stoffe in dunklergefärbte Materialien verwandelt werden, die sich gegenüber atmosphärischer und Lichteinwirkung als haltbar erwiesen haben. Gleichzeitig werden diese Stoffe gegenüber Bakterieneinwirkung widerstandsfähig. Diese auf Oxydation bzw. Dehydrierung beruhenden Effekte entstehen durch den Einbau chinoider Gruppierungen in diese höher molekularen Ausgangsstoffe, welche aromatische Hydroxylgruppen enthaltende Bausteine, wie den Tyrasnnrest, enthalten. Jedoch ist nicht nur der Tyrosinrest für die Reaktion verantwortlich, wie die papierchromgtographische Analyse zeigt.It has now been found that this reaction also applies to animal Fibers, such as wool, silk and collagen, can be applied, which turns these fabrics into darker colored ones Materials are transformed that face atmospheric and exposure to light have proven to be durable. At the same time, these substances are opposed to the effects of bacteria resilient. These effects based on oxidation or dehydration arise by incorporating quinoid groups into these higher molecular weight starting materials, which contain aromatic hydroxyl groups, such as the Tyrasnnrest contain. However, it is not only the tyrosine residue that is responsible for the reaction, as is the case with paper chromatography Analysis shows.

Nach der Einführung von chinoiden Grüppen in die Faserstruktur ist diese der Reaktion mit weiteren Stoffen, wie z. B. Farbstoffen oder Vernetzungsmitteln, zugänglich.After the introduction of quinoid groups into the fiber structure is this the reaction with other substances, such as. B. dyes or crosslinking agents, accessible.

Das Verfahren soll zur Färbung tierischer Fasern und zur Verhinderung von Schäden durch bakterielle Einwirkung Verwendung finden. Beispiel i Gewaschene und entfettete Schafwolle wird in eine gesättigte, wäßrige Kaliumnitrosodisufonatlösung bei Raumtemperatur .eingetragen, wobei ein Puffer zwecks Einstellung auf einen pH-Wert von 5,5 bis 7,5 -zugesetzt werden kann. Das Einsetzen der Reaktion ist an einer Braunfärbung der Wolle erkennbar; die Reaktion ist nach. einigen, Tagen abgeschlossen. Das gefärbte Material wird gewaschen und getrocknet. Die erzielte Färbung ist gegenüber atmosphärischer und Lichteinwirkung beständig. Außerdem ist die Wolle durch die Behandlung gegenüber bakteriellen Einflüssen widerstandsfähiger geworden.The method is said to be used for coloring animal fibers and for prevention of damage caused by bacterial effects. Example i Washed and defatted sheep's wool is dissolved in a saturated aqueous solution of potassium nitrosodisulfonate entered at room temperature, whereby a buffer for adjustment can be added to a pH of 5.5 to 7.5. The onset of the reaction can be recognized by the brown color of the wool; the reaction is after. some days closed. The colored material is washed and dried. The scored Color is resistant to atmospheric and light exposure. Also is the treatment makes the wool more resistant to bacterial influences become.

In gleicher Weise kann Kollagen behandelt werden, das ebenfalls dunklergefärbt und gegenrüber Bakterienangriff widerstandsfähiger wird. Beispiel e Entbastete und gewaschene Seide wird bei Raumtemperatur mit einer etwa 2o/oigen Kaliumnitrosodisulfonatlösung behandelt. Der Eintritt der Reaktion ist an der Dunkelfärbung der Seide zu erkennen. Nach etwa 24 Stunden ist die Umsetzung beendet, man erhält ein gelbbraungefärbtes Material, das in der üblichen Weise versponnen wird, nachdem es vorher noch gewässert und getrocknet wurde. Die so behandelte Seide hat sich auch als chirurgisches Nähmaterial als besonders geeignet erwiesen.Collagen, which also stains darker, can be treated in the same way and becomes more resistant to bacterial attack. Example e deboned and Washed silk is at room temperature with an approximately 20% potassium nitrosodisulfonate solution treated. The start of the reaction can be recognized by the dark color of the silk. The reaction has ended after about 24 hours, and a yellowish-brown color is obtained Material that is spun in the usual way after it has been previously soaked in water and dried. The silk treated in this way has also been used as surgical suturing material proved to be particularly suitable.
