SHEATH-CORE FILAMENT WITH ANTISTATIC CORE

摘要

Antistatic filaments are comprised of a fiberforming polymeric sheath and a fine core of a conductive polymer having a second order glass transition temperature of less than 25.degree.C. Preferred core polymers are N-alkyl polycarbonamides, aliphatic polyesters and polyetheresters. The filaments are spun by careful metering of the core polymer into the fiber-forming sheath polymer at the spinneret.
