(EN) PH-CONTROLLED RELEASE OF DETERGENT COMPONENTS

Abstract
(DE)
Die Erfindung betrifft ein Waschverfahren zum Waschen von textilen Geweben unter Einsatz einer festen, teilchenförmigen Waschmittelzusammensetzung, die ein beschichtetes Alkalisierungsmittel, einen speziell beschichteten Inhaltsstoff sowie ein Acidifizierungsmittel enthält. Nach Auflösung des Mittels liegt der pH-Wert der Waschflotte unter 8 und steigt beim Fortschreiten des Waschvorgangs durch Auflösung des beschichteten Alkalisierungsmittels auf Werte über 8,5, die eine Freisetzung des speziell beschichteten Inhaltsstoffes und eine zeitlich verzögerte Wirkung dieses Inhaltsstoffes ermöglichen.
(EN)
The invention relates to a washing process for washing textile fabrics using a solid, detergent compound in particle form containing a coated alkalizing agent, a specially coated ingredient and an acidifier. After dissolution of the detergent, the pH of the detergent solution is below 8. As the washing process proceeds, pH rises to values above 8.5 through dissolution of the coated alkalizing agent, thus allowing for the release of the specially coated ingredient and time-delayed action of said ingredient.
(FR)
L'invention concerne un procédé de lavage pour laver des tissus textiles à l'aide d'une composition détergente solide particulaire, contenant un agent d'alcalisation enrobé, un ingrédient enrobé de manière spéciale, ainsi qu'un agent d'acidification. Après dissolution de l'agent, le pH de la lessive de lavage est inférieur à 8 et dépasse 8,5 à mesure que le lavage progresse, par dissolution de l'agent d'alcalisation enrobé, ce qui permet une libération de l'ingrédient enrobé de manière spéciale et une action décalée dans le temps dudit ingrédient.
