PROBLEM TO BE SOLVED: To provide a nozzle pack for a low-melting point polymer, capable of dispersing pressure inside a spinning pack so as to scarcely cause an increase in pack pressure, and capable of reducing frequencies of yarn breakage and pack exchange, even though modification or new establishment of melt-spinning facilities, such as installation of each of polymer lines corresponding to polymers having different melting points, is not conducted. SOLUTION: This nozzle pack for the low-melting point polymer is given by using a nonwoven fabric as a primary filter inside the spinning pack, wherein the nonwoven fabric is composed of a synthetic fiber of which the softening temperature is lower than a temperature of a spinning beam for the spun polymer, and has Metsuke (weight per unit area) of≥10 g/m<SP>2</SP>. A polyester fiber is preferably used as the synthetic fiber. COPYRIGHT: (C)2003,JPO
