ABSTRACT:
Disclosed is a stretchable metallized nonwoven web composed of at least one nonwoven web of non-elastomeric thermoplastic polymer fibers, the nonwoven web having been heated and then necked so that it is adapted to stretch in a direction parallel to neck-down at least about 10 percent more than an identical untreated nonwoven web of fibers; and a metallic coating substantially covering at least a portion of at least one side of the nonwoven web. The nonwoven web of non-elastomeric thermoplastic polymer fibers can be a nonwoven web of non-elastomeric meltblown thermoplastic polymer fibers. The stretchable metallized nonwoven web may be joined with other materials to form multi-layer laminates. Also disclosed is a process of making a stretchable metallized nonwoven web.
