The invention relates to a multilayer washable material which comprises at least one layer of a textile material, the layers being joined to one another using an adhesive composition, which is characterized in that in the interfacial region between each pair of layers bearing against one another there is an adhesive composition in the form of a pattern, and no finishing of the multilayer material, as such and/or of a smaller part obtained therefrom, is carried out. One example of a multilayer washable material of this type is a washable underpad comprising a moisture-permeable top layer material (2); a moisture-impermeable bottom layer material (3) and a moisture-absorption element (1) positioned between them, the top layer material (2), the bottom layer material (3) and the moisture-absorption element (1) being joined to one another. The adhesive composition used is preferably a moisture-curing reactive polyurethane hotmelt material.

The invention claimed is: 1. A multilayer washable material which comprises:a moisture-permeable top layer material (2) being substantially hydrophobic, a moisture-impermeable bottom layer material (3), and at least one layer of a textile material used as a moisture-absorption element (1) positioned between the top layer and the bottom layer;the layers being joined to one another by means of an adhesive composition, wherein an interfacial region between each pair of layers bearing against one another exists;wherein in the interfacial region between each pair of layers bearing against one another there is an adhesive composition in the form of a pattern which is sufficiently dense to prevent wrinkling, and which is sufficiently open to prevent the material from becoming inflexible;wherein the pattern in which the adhesive composition is present is selected from:a) a dot lining pattern,b) separately positioned pattern parts which are separated by regions where there is no adhesive composition,c) a number of pattern parts (4, 22) which are identical in shape and one or more pattern parts (21) of a different shape, wherein the different pattern shape is a border, the external dimensions of which correspond to the dimensions of a use product, which it is desired to form from the multilayer material by dividing up the latter,d) the patterns described under b) and/or c), with one or more pattern parts being formed from a dot lining pattern,e) a dot lining pattern as described under a) in which there are parts without any dots,and combinations of the patterns described under a) to e);wherein the multilayer material is a washable underpad;wherein the moisture-permeable top layer is made of a fraying-free fabric;wherein optionally no finishing of the multilayer material, as such and/or of a smaller part obtained therefrom, is carried out; andwherein a quantity of applied adhesive composition is from 6 to 40 g/m2.
