Abstract
Absorbent laminates, which may be used as or in diapers, incontinence pads, sanitary napkins, tampons or wound dressings, comprise a hydrophilic layer adjacent a water-permeable fibrous web. Fluid-transporting wicks extend from within the fibrous web into the hydrophilic layer, and are preferably formed by needling. The hydrophilic layer is preferably a peat moss composite board, and the fibrous web is preferably a nonwoven polyester fleece.
