Abstract
PURPOSE: To improve the coherency of a filament yarn, and to eliminate the broken filament, by means of a yarn collecting guide equipped between the yarn press guide belot the oil applicator and the godet roll, and by controlling the tension difference between the two guides within values expressed by specific relations.
CONSTITUTION: The yarn collecting guide 12 is equipped between the yarn press guide 8 below the oil applicator 7 and the first godet roll 5, 1m or more apart, for melt spinning, and the difference T between the tensions T1 and T2 at the outlet and the inlet of the guide 8 is set to satisfy formula I:{T is T2WT1; To is the theoretical tension value of a completely uncollected yarn between the guides 8 and 12, and formula II [Red is the Reynolds number, and formula III (D is the diameter of a filament; (V is the spinning speed; n is the number of filaments; ρa is the density and formula IV; μa is the viscosity of normal air and formula V)]; Tc is formula IV (Redc is formula VII)}.
