ABSTRACT:
Thin thermoplastic foil is applied with the aid of a wide slit nozzle and an electrostatic discharge electrode to a nonwoven mat of thermoplastic fibers and filaments on a bonding roller and the resulting composite is then subjected to biaxial stretching utilizing at least some of the bonding heat carried by the composite. The composite may then be thermally fixed before being cooled to room temperature.
