A wipe comprising a high internal phase inverse emulsion disposed in a discontinuous pattern on a substrate. The pattern provides areas coated with the emulsion and areas free of the emulsion. Preferably the emulsion is disposed so that the surface area to volume ratio of the emulsion is minimized. The emulsion locally expresses water during use upon the application of pressure to the wipe. The water is useful for cleaning. The discontinuous pattern of the emulsion provides regions of the substrate which are wetted during use and regions which may remain dry. The wetted regions transfer water to the surface to be cleaned. The dry regions then remove the water from the surface for more efficacious cleaning.
L'invention concerne un chiffon qui contient une émulsion inverse à phase interne élevée, déposée sur un substrat selon un motif discontinu. Ce motif présente des zones recouvertes par l'émulsion et des zones exemptes d'émulsion. De préférence, l'émulsion est disposée de manière à réduire au minimum le rapport entre la surface de chaque zone et le volume de l'émulsion. A l'utilisation, lorsqu'on exerce une pression sur le chiffon, l'émulsion dégage localement de l'eau. L'eau est utile au nettoyage. Le motif discontinu de l'émulsion permet d'avoir des zones du substrat qui sont humidifiés à l'utilisation et des zones qui peuvent rester sèches. Les zones humides dégagent de l'eau sur la surface à nettoyer, puis les zones sèches enlèvent l'eau de la surface, ce qui permet un nettoyage plus efficace.
