assignment ; Has excellent dimensional stability, room chamfer inhibitory effect, plate depression preventing effect, Halle tion inhibition effect could not be obtained in the conventional monofilaments, and also high-shi painter possible three fineness and also provides a high strength, high modulus polyester monofilament . ; It means to resolve ; At least 80 mol% of the structural unit is in the core-sheath type composite polyester monofilament of polyethylene terephthalate, A: a is 0.70 or more intrinsic viscosity of the core component polyester, and an intrinsic viscosity of 0.55 in the polyester of the sheath component, - in the range of 0.60 and, B: core weight ratio of the components is 50% ~ 70%, C: the fine metal particles to at least a second component 0.2 to 0.4 or is contained by weight%, C ': at least a second component, the metal fine particles 0.2 to 0.4% by weight and contained the organic pigment and 0.2 to 1.0% by weight, D: the fineness of the monofilament in the 5 to 15dtex, the modulus of elongation when the work 5% 3 ~ 4.5cN / dtex, an elongation at break of 20 to 40 %, satisfies the above, E: is a free shrinkage of the innermost layer part was measured over a period of 10 days from the day after the wound product below 0.3%, F: polyester monofilament of the fiber longitudinal direction with respect to 100,000 10㎛ fiber diameter in meters thick or more additional words (spun dyed) polyester monofilament that satisfies 1 or less, or more a ~ F. ; Filament, polyester
