ABSTRACT Alternate-twist plied yarns, wherein a secondary strand for providing a special effect is plied with at least two alternately, false-twisted primary strands, are made by converging the secondary strand with the primary strands downstream of the point at which the primary strands are converged. Node centers at the twist reversal points for the secondary strand are displaced with respect to node centers of the primary strands. Improved effectiveness from an antistatic secondary strand in the plied yarn can be obtained by this method. Where a node of a secondary strand overlaps a node of the primary strands, whether or not the node centers are displaced, a preferred configura- tion is one wherein the secondary strand forms a node by wrapping around only one of the primary strands in a portion of the primary node.
