Abstract of the Disclosure Absorbent paper products, such as paper towels, are disclosed which have a combination of high absorbent capacity and a moderate to low rate of absorbency for hand protection. These properties can be produced, for example, using a throughdried basesheet, such as an uncreped throughdried sheet, in which at least one surface of which has been printed with a patterned moisture barrier coating and creped. The presence of the moisture barrier coating on the surface retards the absorbent rate for that side of the sheet while allowing a significant amount of liquid to pass through to the center of the sheet.

L'invention concerne des produits de papier absorbant tels que des essuie-mains en papier, qui présentent en combinaison un pouvoir absorbant élevé et un taux d'absorption modéré à faible pour protéger les mains. On peut obtenir ces propriétés, par exemple, en utilisant une feuille de base séchée transversalement, telle qu'une feuille non crêpée séchée transversalement, qui comprend au moins une surface imprimée comportant un revêtement barrière contre l'humidité pourvu de motifs, et crêpée. La présence dudit revêtement sur la surface permet de retarder le taux d'absorption de cette face de la feuille et de laisser passer une quantité importante de liquide vers le centre de la feuille.
