USE OF OPEN-CELL ELASTIC FOAMED MATERIALS BASED ON MELAMINE/FORMALDEHYDE CONDENSATION PRODUCTS IN HYGIENE ARTICLES

摘要

The invention relates to the use of open-cell elastic foamed materials based on melamine/formaldehyde condensation products in hygiene articles for absorbing, distributing and immobilizing body fluids. The invention also relates to hygiene articles, which are constructed from a combination comprised of a liquid-impermeable layer, of an absorbent intermediate layer and of a liquid-permeable layer, whereby for absorbing, distributing and immobilizing body fluids, the absorbent intermediate layer is comprised of an open cell elastic foamed material made of melamine/formaldehyde condensation products having a density ranging from 5 to 200 g/l, a specific surface (determined according to the B.E.T. method) of greater than 0.5 m<2>/g and having a free swell capacity of greater than 20 g/g.
