A wiper that provides a controlled release anti-microbial agent has a substrate layer to which the anti-microbial agent is adhered. In addition, the wiper will have one or more laminate layers, at least one of which will be absorbent. Various anti-microbial agents such as silver containing additives, calcium hypochlorite, and chlorine dioxide generating compounds may be employed. The substrate layer may be a poly(ethylene vinyl acetate) meltblown web and the laminate layer may be a hydroentangled composite absorbent fabric.
L'invention concerne un chiffon pourvu d'un agent antimicrobien à libération contrôlée, possédant une couche substrat à laquelle on fait adhérer ledit agent antimicrobien. En outre, ce chiffon possède une ou plusieurs couches stratifiées dont au moins une est absorbante. Plusieurs agents antimicrobiens tels que des additifs contenant de l'argent, l'hypochlorite de calcium et des composés générant du dioxyde de chlore peuvent s'utiliser. La couche substrat peut être une bande de fusion-soufflage en poly(éthylène acétate de vinyle), les couches stratifiées pouvant être constituées d'un tissu absorbant composite entremêlé par procédé hydrique.
