Airlaid fibrous webs having a primary layer having discrete particles of absorbent gelling material dispersed through at least a portion of the web airlaid over a dusting layer of essentially hydrophilic fiber material. The dusting layer acts to block the passage of particles injected in the stream of fibers forming the primary layer so as to minimize equipment plugging problems and the loss of particles or fibers through the foraminous forming element and to provide a more efficient absorbent core.
