Patent ID: 8057885

Claim:
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; and wherein a quantity of applied adhesive composition is from 6 to 40 g/m 2 .
