Abstract

A liquid absorbent structure is made by dry laying a fibrous web having incorporated therein a superabsorbent material, and applying an aqueous composite stabilizer to at least one surface of the web. The aqueous composite stabilizer imparts integrity to the resulting structure without substantially impairing the effectiveness of the superabsorbent material to absorb liquid while forming the absorbent structure without removing the water from aqueous composite stabilizer or drying out the absorbent structure. The absorbent composite absorbs the water from the aqueous composite stabilizer. The absorbent composite comprises about 70% by weight of a superabsorbent material.
