Abstract

PURPOSE: Polyamide multiple yarns that have been simultaneously melt extruded are drawn by coiling them around the second goddet roller heated to a specific temperature by prescribed turns and taken up at a high speed, thus permitting simple threading operations and preventing the yarn fluctuation and fluff formation.
CONSTITUTION: Multiple yarns Y of polyamide (8 yarns are shown in the figure) are simultaneously melt extruded from the spinneret 1, solidified by cooling in the cylinder 2, lubricated by applying a finishing oil and taken up with the first goddet roller 5, drawn between the first roller and the second goddet roller 6 that revolves faster than the roller 5 and is heated on the surface to TgW(Tm-10)°C where Tg is the glass transition temperature of the melt-extruded polyamide and Tm is the melting point by winding by less than 1 turn, heat treated around the second goddet roller 6 and taken up at a speed of over 3,000m/min. At this time, eight yarns Y is divided two groups including 4 yarns each with guide 7 and further divided into each yarn with traverse guide 8, then each yarn is wound up.
