ABSTRACT:
A small diameter ionizing cord for use in an apparatus through which insulative material flows or is propelled. The ionizing cord has an outer surface and includes three or more strands of electrically non-conductive fibers braided to form a smooth cord having an effective diameter of about 0.5-6 mm. At least one of the strands is a static control strand including a multiplicity of electrically conductive microfibers being in electrically conductive communication with one another along the length of the strand. The microfibers are selected to provide a multiplicity of ionizing points disposed along the length of the cord and exposed at or extending minimally above the outer surface such that, when the strand is electrically grounded or electrically charged, air between the ionizing points and the material passing the outer surface is sufficiently ionized to remove static charge from the material or to attract or repel the material to or from the apparatus surface. The microfibers of the ionizing cord typically are about 0.5-50 .mu.m in diameter and about 2-8 cm long, and carbon, metal coated carbon, copper, stainless steel, metal coated acrylic, metallized acrylic, or electrically conductive polymers. Methods for fabricating and using the small diameter ionizing cord are also disclosed.
