Superfine porous dacron irregular-shaped draw textured yarn (DTY) production process

The invention discloses a superfine porous dacron irregular-shaped draw textured yarn (DTY) production process which includes polyester pre-oriented yarn (POY) protofilament, a pre-network, a first yarn feeding roller, a first texturing heater, a cooling plate, a false twister, a second yarn feeding roller, a second auxiliary roller, a second heat box, a third yarn feeding roller, an oil applying rod and DTY winding molding. The second yarn feeding roller speed is 660m/min-700m/min, and drawing multiple of the second yarn feeding roller is 1.610-1.650. Deforming temperature of the first texturing heater is 183 DEG C-188 DEG C, and sizing temperature of the second heat box is 170 DEG C-180 DEG C. A friction disc of the false twister is 1-4-1 disc combination, and D/Y ratio is 1.55-1.63. Sizing overfeeding rate is 4.25-4.90, winding overfeeding rate is 5.00-5.35, and overfeeding rate of the second auxiliary roller is 3.00-3.50. Flannel fabric produced through the process has the performance of rigidity, glittering, fluffiness, pilling resistance, staining resistance and the like.
