摘要: The productivity of the conventional melt spinning process for producing undrawn polyhexamethylene adipamide carpet and tire yarns is increased by utilizing a heat feed roll (e.g. 80.degree. C.) rather than an unheated feed roll and by eliminating the conventional steam conditioning of the yarn and the convergence guide(s) associated therewith.
