Abstract
Fibrous webs are bonded by passing through a nip comprising an anvil and a hammer vibrating at high frequencies in the presence of uncombined liquid. The liquid is moved within the web causing rearrangement and entanglement of the fibers resulting in improved web properties such as strength, drape, and softness. The nature of the rearrangement and entanglement may be varied to produce random or highly entangled webs having correspondingly varying properties. Other embodiments include the use of additional fibers or other materials in the liquid or in the web and the bonding of multiple layers.
