Abstract

See full text

A process for producing an antistatic yarn includes the steps of: (a) providing antistatic composite filaments having carbon black dispersed therein; (b) advancing the antistatic composite filaments to a first heating zone at a first advancing speed which ranges from 230 m/min to 330 m/min; (c) drawing the antistatic composite filaments from the first heating zone to a false twist zone at a second advancing speed such that a draw ratio of the second advancing speed to the first advancing speed ranges from 1.5 to 1.75, thereby obtaining false twisted filaments; and (d) heat-setting the false twisted filaments so as to obtain a permanent antistatic crimped yarn.
