Abstract

FINELY-DIVIDED, ELECTRICALLY-CONDUCTIVE PARTICLES ARE UNIFORMLY SUFFUSED IN A FILAMENTARY POLYMER SUBSTRATE AS AN INDEPENDENT PHASE IN AN ANNULAR REGION LOCATED AT THE PERIPHERY OF THE FILAMENT AND EXTENDING THE ENTIRE LENGTH THEREOF. THE ELECTRICALLY-CONDUCTIVE PARTICLES ARE EMPLOYED IN AN AMOUNT SUFFICIENT TO RENDER THE ELECTRICAL RESISTANCE OF THE FILAMENT NOT MORE THAN ABOUT 10**9 OHMS/CM. THE FILAMENT FIND SPECIAL UTILITY IN THE FABRICATION OF ANTISTATIC FABRICS AND FLOOR COVERINGS.
