Description
Verfahren zur wasserabstoßenden Imprägnierung von Rückzugsbändchen für Tampon Zusatz zum Patent B27 695 Das Verfahren zur wasserabstoßenden Imprägnierung von Rückzugsbändchen für Tampon aus Faserstoffen, welche vornehmlich vor dem Pressen zusammen mit dem Bändchen oder der Schnur mit kationaktiven, bakterizid wirkenden Stoffen behandelt sind, besteht nach dem Patent 827 695 darin, daß Temperatur und Konzentration einer zur Bildung eines schwerlöslichen hydrophoben Niederschlages bestimmten Metallsalzlösung, z. B. einer Aluminiumacetatlösung, so gewählt werden, daß unter dem Niederschlag noch eine Schicht aus unumgesetzten, anionaktivem Stoff, z. B. bestehend aus einer Seifenlösung, vorhanden ist.Process for the water-repellent impregnation of retraction tapes for tampon addition to patent B27 695 The procedure for water-repellent impregnation of retraction tapes for tampons made of fibers, which are mainly used before pressing together with the ribbon or cord with cationic, bactericidal effects Substances are treated, is according to the patent 827 695 in that temperature and Concentration of a hydrophobic precipitate that is difficult to dissolve certain metal salt solution, e.g. B. an aluminum acetate solution, can be chosen so that under the precipitate there is still a layer of unreacted, anionic substance, z. B. consisting of a soap solution is present.
Der Gegenstand vorliegender Erfindung besteht nun darin, daß bei einer Imprägnierung mit einer mindestens o,o3°/Oigen, vornehmlich olI°/Oigen Kaliumstearatlösung bei einer Temperatur von 40 bis 1000 C, vornehmlich etwa 500 C, und anschließende Führung durch eine mindestens o,I°/Oige, vornehmlich o,3010ige Aluminiumacetatlösung bei Temperaturen bis zu Zimmertemperatur, z. B. 200C, eine ebenfalls völlige Aufhebung der Netzwirkung des Desinfektionsmittels erreicht wird. The object of the present invention is that at an impregnation with at least 0.03%, primarily oil, potassium stearate solution at a temperature of 40 to 1000 C, mainly about 500 C, and then Guided tour through an at least 0.1%, primarily 0.10% aluminum acetate solution at temperatures up to room temperature, e.g. B. 200C, also a complete cancellation the wetting effect of the disinfectant is achieved.
Das Kaliumstearat muß entweder in destilliertem oder sonstwie enthärtetem, vollkommen reinemWasser gelöst werden, da schon geringste Mengen an Härtebildnern die sehr geringen Stearatmengen ausfällen. The potassium stearate must either be distilled or otherwise softened, completely pure water, since even the smallest amounts of hardness builders precipitate the very small amounts of stearate.
Beim Eintauchen des Bandes in die Kaliumstearatlösung nimmt das Band außer dem Stearatanteil, der der Ausgangslösung entspricht, noch durch Adsorption einen zusätzlichen Anteil an Stearat auf, der etwa einer Menge von 60 01o des gelösten Anteiles entspricht. When the tape is immersed in the potassium stearate solution, the tape picks up apart from the stearate content, which corresponds to the starting solution, also by adsorption a additional portion of stearate, which is about an amount of 60 01o of the dissolved Proportion corresponds.
Hierdurch wird die Lösung während der Verarbeitung laufend an Kaliumstearat ärmer. Es erweist sich daher als zweckmäßig, die Tauchwärme zu Beginn unit einer o,I0l,igen Lösung zu füllen und von Zeit zu Zeit o,20/0ige Lösung zum Auffüllen bis zum Ausgangsniveau zuzugeben. Die Kaliumstearatlösung muß im Betrieb auf etwa 500 C gehalten werden.This means that the solution is constantly getting potassium stearate during processing poorer. It therefore proves to be expedient to use the immersion heat at the beginning of a unit o, 10l, igen solution to fill and from time to time o, 20/0 solution to top up to admit up to the starting level. The potassium stearate solution must be in operation to about 500 C.
Anschließend erfolgt, am besten in noch nassem Zustand, eine Tränkung in einem Bad mit 0,3%iger Aluminiumacetatlösung bei Zimmertemperatur oder darunter. Hierauf wird das Bändchen getrocknet und an dem Tampon befestigt. This is followed by an impregnation, ideally when it is still wet in a 0.3% aluminum acetate solution bath at room temperature or below. The ribbon is then dried and attached to the tampon.
