Abstract
Composite nonwoven non-elastic web materials and methods of forming the same are disclosed. The composite nonwoven non-elastic web materials are formed by hydraulically entangling a laminate of (a) at least one layer of meltblown fibers and (b) at least one layer of nonwoven material. The nonwoven material can comprise at least one of pulp fibers, staple fibers, meltblown fibers and substantially continuous filaments. The nonwoven material can also be a net, foam, etc. Each of the meltblown fiber layer and the nonwoven material layer is preferably made of non-elastic material.
