Abstract

Disposable multi-layer diaper comprises a porous fibrous facing layer to be brough into contact with an infant's skin and a water-impervious backing sheet with a multi-layer batt between the facing layer and backing sheet. The batt comprises two differently sized superposed layers of highly porous loosely compacted cellulose fibres, the smaller layer having an integrally formed paper-like, densified, highly compacted cellulose fibrous layer, positioned in face-to-face engagement with the backing sheet. The smaller layer and the margins of the larger layer extending beyond the smaller layer are adhered to the backing sheet.
