Abstract
The sticking between an array of melt spun eccentric bicomponent filaments converged together into yarn is avoided by selecting the filaments being converged so that the thin sheath regions of the filaments do not contact one another and conducting the convergence in two steps if the number of filaments required for the yarn is too great for convergence in one step while avoiding the aforesaid contact.
