Embodiment Construction
[0012] The present invention is further described below in conjunction with embodiment:
[0013] Ultra-fine porous polyester special-shaped DTY, the process flow is: POY raw yarn → pre-netting → first feeding roller → first deformation heating box → cooling plate → false twister → second feeding roller → middle network (optional) → The second heating box→the third feeding roller→oiling roller→DTY winding and forming.
[0014] Among them, the speed of the first wire feeding roller is 400m / min~435m / min, the speed of the second feeding roller is 660m / min~700m / min, the speed of the third feeding roller is 628m / min~670m / min, stretching The multiple is 1.610~1.650, the deformation temperature of the first deformation hot box is 183°C-188°C, the setting temperature of the second hot box is 170°C-180°C; the friction disc of the false twister is a 1-4-1 disc combination, D / The Y ratio is 1.55-1.63 and the setting overfeeding rate in the winding forming process is 4.25-4.90 (the third...
