Abstract
Antistatic spunbonded nonwoven fabrics are provided. The fabrics of the invention include a plurality of substantially continuous electrically nonconductive filaments formed of a thermoplastic polymer, a plurality of electrically conductive filaments distributed among the electrically nonconductive filaments throughout the fabric, and a multiplicity of discrete bond sites bonding together the electrically nonconductive and the electrically conductive filaments to form a coherent fabric.
