Patent

CA 2287882

There is provided a distribution material for personal care products which is a fabric which wicks artificial menses according to a horizontal wicking test a distance of about 1 inch in less than about 1.5 minutes. Materials meeting this performance criteria generally have a pore size distribution with a high percentage (usually more than 50 percent) of pore diameters between about 80 and 400 microns and a density below about 0.15 g/cc. There is also provided a personal care product system having a distribution/retention layer and a pad shaping layer wherein each layer has a stain length ratio of 0.5 or less and the distribution/retention layer has a saturation profile of 4 or less.

L'invention concerne un matériau de distribution pour produits d'hygiène personnelle. Ce matériau est une texture qui, dans un test de capillarité horizontale, draine des menstrues artificielles sur une distance d'environ 1 pouce en moins d'1,5 minutes environ. Les matériaux qui satisfont à ce critère de performance présentent généralement une mauvaise répartition dimensionnelle des pores avec un pourcentage élevé (habituellement supérieur à 50 pour-cent) de pores ayant des diamètres compris entre 80 et 400 microns et une densité inférieure à environ 0,15 g/cc. L'invention concerne en outre un système pour produit d'hygiène personnelle comprenant une couche de distribution/rétention et une couche formant une garniture, dans laquelle chaque couche présente un rapport de longueur de tache égal ou inférieur à 0,5 et la couche de distribution/rétention présente un profil de saturation égal ou inférieur à 4.
