Abstract
A fiber product comprises dry discontinuous fibers having a starch binder on at least a portion of the fiber surfaces, at least about seventy percent of the starch binder coated fibers being unbonded to one another, solid particles are adhered to the fibers by the binder without the binder entirely coating the particles. The fibers may be air laid into a web or formed into an absorbent structure. Superabsorbent particles are a specific example of the particles which may be adhered to the fibers.
