Abstract: 1. A PROCESS FOR THE MANUFACTURE OF ANTISTATIC POL AMIDE FILAMENTS WHICH COMPRISES: FORMING A MOLTEN MIXTURE OF (A) A FILAMENT-FORMING SYNTHETIC LINEAR ALIPHATIC POLYAMIDE HAVING RECURRING AMIDE GROUPS IN THE BACKBONE AND HAVING A RELATIE VISOSITY IN THE RANGE OF 1.5 TO 2.9, MEASURED AS A 1% W./W TOGETHER WITH (B) FROM 2 TO 15% BY WEIGHT, BASED ON THE FILAMENTS OR FIBERS, OF AN ALKOXYLATED POLYAMIDE MANUFACTURED BY REACTION OF A OLYMIDE SELECTED FROM THE CONSISTING OF THE POLYCONDENSATES OF LACTAMS OF 4 TO 12 CARBON ATOMS AND POLYCONDENSATES OF THE SALTS OF DIAMINES CONDENSATES OF LACTAMS OF 4 TO 12 CARBON ATOMS AND DICARBOXYLIC ACIDS OF 4 TO 12 CARBONS ATOMS WITH A 1,2-ALKYLENE OXIDE IN A WEIGHT RATIO FO FROM 1:2 TO 1-5 AND TO PROVIDE A TOTAL MOLECULAR WEIGHT OF 10,000, COMPONENTS (A) AND (B) BEING SO THROUGHLY MIXED THAT SAID ALKOXYLATED POLYAMIDE IS PRESENT IN THE FINISHED FILAMENTS IN THE FORM OF PARTICLES HAVING A DIAMETER OF NOT MORE THAN 0.1; AND FINISHED FILAMENTS IN THE FORM OF PARTICLES HAVING A FILTER HAVING A PORE WIDTH OF NOT MORE THAN 20; AND SUBSEQUENTLY MELT SPINING SAID MIXTURE BEING MAINTAIND IN THIS MENTS, THE MOLTEN MIXTURE BEING MAINTAINED IN THIS PROCESS AT ELEVATE TEMPERATURES OF UP TO NOT MORE THAN 290*C. FOR A TOTAL PERIOD OF NOT MORE THAN 30 MINUT4S.
