[0031]Produced on the Murata (MUTATEC) 33H (S+Z) machine, the sea-island yarn POY of 150dtex / 36f*37I specification is used as the first raw material yarn A, and the 150dtex / 36f round polyester cationic POY is used as the first raw material yarn B. The two bundles of filaments are drawn out from the original wire frame, separated and sequentially passed through the first double cutter 1, the first micro-moving filament guide 2, and the first wire feeding roller 3, and then enter the first hot box 4. The filament in the box 4 is subjected to 1.84 times the stretching of the second wire feed roller 11 (the draw ratio is generally 1.5-2.2) and The twisted deformation of the torsion transmitted from the false twister 8 has the characteristics of a textured yarn. Guided by the skid wire guides 5 and 6, the cooling plate 7 cools down to reduce the temperature of the filaments, and then enters the false twister 8 for false twisting. 115 degrees), the contact pressure of the apron is ...
