Abstract
An alternate S and Z twist plied yarn made from individual singles yarns. The apparatus twists the singles yarns as they move in a path through the process, twisting the individual yarns in either an S or Z direction. The bonding of the ply-twisted yarns at a node while applying twist forms a bond characterized by numerous individual spaced bond sites between individual filaments that are distributed throughout the bond.
