A nonwoven wipe having a reversible sanitizer indicator for multiple uses and recharges is provided. The nonwoven wipe includes a cloth-like nonwoven fabric coated with a reversible color- changing ink formulation. During use, the nonwoven wipe is impregnated with a quaternary ammonium compound-based sanitizer. When the level of free quaternary ammonium compound falls below a threshhold level, the color-changing ink formulation changes from a first color to a second color, indicating the need to recharge the wipe. When the nonwoven wipe is recharged with sanitizer solution, the color-changing ink formulation changes back to the first color.
La présente invention concerne un chiffon non-tissé multi-usages comportant un indicateur réversible de présence de désinfectant, ainsi que des recharges. Ledit chiffon non-tissé comprend un géotextile non-tissé ressemblant à du tissu qui est revêtu d'une composition d'encre capable de changer de couleur de façon réversible. Lors de l'utilisation, le chiffon non-tissé est imprégné d'un désinfectant à base d'un composé d'ammonium quaternaire. Lorsque le niveau de composé d'ammonium quaternaire libre tombe au-dessous d'un niveau seuil, la composition d'encre capable de changer de couleur passe d'une première couleur à une seconde couleur, indiquant qu'il est temps de recharger le chiffon. Lorsque le chiffon non-tissé est rechargé en solution désinfectante, la composition d'encre capable de changer de couleur reprend sa couleur initiale.
