120℃とした。Example 1 Polyethylene terephthalate with an intrinsic viscosity of 0.74 (containing 0.5% TiO 2 as a matting agent) copolymerized with 5 mol% of isophthalic acid as a high-shrinkage component, and polyethylene terephthalate with an intrinsic viscosity of 0.4 as a low-shrinkage component. 1' and 2' separately at a polymer temperature of 285°C using the spinneret nozzles shown in Figures 4 to 6.
After discharging at a discharge ratio of 1:1, collision bonding was performed directly below the mouthpiece, then cooling and oiling were performed.
The film was taken up at a speed of m/min, and without being wound up, it was preheated at 95°C and stretched 3.87 times. Next, after heat treatment at 160°C, it is supplied to a heated fluid push nozzle with an overfeed of 12%, subjected to crimp development treatment, and wound up.
A crimped yarn of 300 denier/96 filaments was obtained. At this time, the heating fluid pressure in the heating fluid pushing nozzle was 3.5 Kg/cm 2 and the heating fluid temperature was 180°C. In No. 1, after both components were discharged from a pair of circular spinneret nozzles, they were impact-bonded directly below the spinneret surface to form a solid side-by-side type composite fiber. In addition, No. 8 does not perform treatment with the heated fluid push nozzle, No. 9 does not heat the fluid in the fluid push nozzle and keeps it at room temperature, and No. 10 does not heat the fluid at room temperature.
The temperature was 120℃.
