Abstract: A dimensionally stable bonded nonwoven fibrous web formed by extruding melt blown fibers of a polymeric material, collecting the melt blown fibers as an initial nonwoven fibrous web, and annealing the initial nonwoven fibrous web with a controlled heating and cooling operation, is described. The bonded nonwoven fibrous web shrinkage is typically less than 4 percent relative to the initial nonwoven fibrous web.
