ABSTRACT:
The present invention relates to webs made of cellulose fibers admixed with thermobonding fibers, wherein the web surfaces are sealed to a greater or lesser extent by adding thereto a binder in modest amounts. The binder is applied without any attempt to provide deep penetration of said binder into the web material. By applying the binder in the form of a foam, a minimum of binder is required to provide bonded webs exhibiting minimal linting.
