ABSTRACT OF THE DISCLOSURE Highly absorbent low density fibrous struc- tures such as webs or batts formed from mixtures of powdered or microcrystalline hydrogel pre- parations with surfactant treated filler materials having a particle size equal to or greater than the hydrogel particle size. Absorbent materials of the invention exhibit good wicking properties and result in more efficient use of hydrogels by minimizing gel blocking. Additional improvements include reduced dusting, improved stabilization and somewhat higher absorbency when compared with hydrogel materials alone. Uses for these materials include, by way of example and not limitation, disposable diapers, incontinent pads, sanitary napkins, wipes, surgical sponges and the like.
