Abstract
Singles yarns are formed from a synthetic material, twisted in one direction, heat-set, cooled and false-twisted in the opposite direction. Two similarly treated strands are joined at their nodes and plied, resulting in an improved ply-twist singles twist ratio. The first twisting and heat-setting can be done concurrently using jet twisting with steam, and apparatus for accomplishing this is disclosed.
