ABSTRACT:
A batt including a major percent of thermo-mechanical wood pulp fibers is stabilized by the inclusion of a minor percent of thermoplastic fibers, which latter fibers are heat fused to one another and to the thermo-mechanical wood pulp fibers at fiber intersections to provide a supporting network which inhibits collapse and agglomeration of the thermo-mechanical wood pulp fibers.
