ABSTRACT:
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.
