A foam-fiber composite, useful as an absorbent for sanitary napkins is disclosed. It is a resilient, absorbent structure made from large particles of an amino-ether hydrophilic foam (and optionally a superabsorbent and wood pulp), which by use of a carding machine is uniformly distributed in, and heat bonded to a fibrous matrix, which matrix is preferably made from two different kinds of fibers, one of which is low melting at the bonding temperatures used in the oven, e.g., polyethylene and the other high melting, e.g., polyester.
