Abstract

Procedure for preparing absorbent structures, characterized in that it comprises the steps of: refining by pressing wood to prepare non-delignified defibrated wood pulp having an average fiber length of at least 0.8 millimeters and an average fiber diameter within the range comprised between approximately 0.02 millimeters and approximately 0.06 millimeters; increase the hydrophilicity of the fiber surface of the wood pulp; fold and grind the hydrophilic wood pulp; air-spread the pulp of ground, hydrophilic defibrated wood to form a fibrous web; and compressing the fibrous web to provide an absorbent structure having a density of between 0.04 grams per cubic centimeter and 0.18 grams per cubic centimeter.
