Description

Verfahren zum Schutz der Wolle gegen Bakterienschädigung In der Patentschrift 463 472 ist ein Verfahren zum Schutz der Wolle gegen Bakterienschädigung beschrieben, welches darin besteht, daß man die Wolle vor oder nach einer alkalischen Opperation des Fabrikationsganges, insbesondere Wäsche, Färben, Walke, mit Lösungen von Sulfosäuren alkylierter Naphthaline behandelt.Method of protecting wool against bacterial damage In the patent 463 472 describes a method for protecting wool against bacterial damage, which consists in removing the wool before or after an alkaline operation of the manufacturing process, in particular washing, dyeing, fulling, with solutions of sulfonic acids treated alkylated naphthalenes.

Es wurde nun gefunden, daß man auch durch eine Behandlung der Wolle mit Lösungen von Sulfosäuren alkylierter Naphthaline, welche vor der zum Karbonisieren üblichen Behandlung mit Schwefelsäure vorgenommen wird, der Wolle eine erhebliche Widerstandsfähigkeit gegen Bakterienangriffe verleihen kann.It has now been found that you can also treat the wool with solutions of sulfonic acids alkylated naphthalenes, which are used for carbonation before usual treatment with sulfuric acid is carried out, the wool a considerable Can impart resistance to bacterial attack.

Es ist bereits vorgeschlagen worden, aromatische Sulfosäuren oder deren Salze dem Karbonisierbade zuzusetzen. Durch diese gleichzeitige Einwirkung der zum Karbonisieren verwandten Schwefelsäure und der aromatischen Sulfosäure auf die Wolle wird jedoch eine Schutzwirkung gegen Bakterienangriffe nicht erzielt, da im Karbonisierbade die Reaktion zwischen der Schwefelsäure und der Wolle so stark ist, daß hierdurch die Einwirkung der dem Karbonisierbade zugesetzten aromatischen Sulfosäure auf die Wollsubstanz weitgehend verhindert wird. Infolgedessen wird eine derartig behandelte Wolle nach dem Neutralisieren ebenfalls sehr schnell durch Bakterientätigkeit zerstört. Im Gegensatz hierzu zeigt die nach dem vorliegenden Verfahren in einem besonderen Arbeitsgang vor dem Karbonisieren mit Sulfosäuren alkylierter Naphthaline behandelte Wolle nach dem dem Karbonisieren folgenden Entsäuern eine erhebliche Widerstandsfähigkeit gegen Bakterienangriffe.It has already been proposed to use aromatic sulfonic acids or add their salts to the carbonation bath. Through this simultaneous action the sulfuric acid used for carbonation and the aromatic sulfonic acid However, the wool does not have a protective effect against bacterial attacks, because in the carbonation bath the reaction between the sulfuric acid and the wool is so strong is that this reduces the effect of the aromatic substances added to the carbonation bath Sulphonic acid on the wool substance is largely prevented. As a result, a wool treated in this way also very quickly after neutralization due to bacterial activity destroyed. In contrast, the present method shows in one Special process before carbonizing naphthalenes alkylated with sulfonic acids treated wool after the deacidification following the carbonization a considerable Resistance to bacterial attacks.

Beispiel 5o kg Wollmaterial werden 1/2 Stunde bei 50° C in einem -Bade behandelt, das xo g Dibutylnaphthalinsulfosäure im Liter enthält; danach wird wie üblich karbonisiert und entsäuert.Example 50 kg of wool material are bathed in a bath at 50 ° C. for 1/2 hour treated that contains xo g of dibutylnaphthalene sulfonic acid per liter; after that becomes like Usually carbonized and deacidified.
