Abstract
A method for forming a stabilized airlaid layer (86) can include an airforming of a substantially unbonded fibrous layer (66) which includes absorbent fibers and binder-fibers. The fibrous layer (66) is exposed to high-frequency electromagnetic energy during a distinctively short activation period to activate the binder-fibers to provide the stabilized, airlaid layer (86).
