| description | The invention belongs to the technical field of polyester pre-oriented yarns, and relates to a polyester pre-oriented yarn for direct weaving and a preparation method of the polyester pre-oriented yarn for direct weaving, polyester melt is sequentially subjected to metering, melt extrusion, cooling, oiling, hot box treatment, first godet treatment, pre-network treatment, second godet treatment and winding to obtain 758-1050dtex/192f trilobal profiled fibers; the first godet roller and the second godet roller are non-heating rollers; a three-section side-blowing cooling process is adopted for cooling; the cooling air speed of the three sections increases gradually from top to bottom; the cooling air blowing direction is inclined upwards by 30-45 degrees; the speed of the first godet is 2800-3200 m/min, and the speed of the second godet is 3500-4000 m/min; the set temperature of the hot box is higher than the glass transition temperature of polyester. According to the method disclosed by the invention, the prof |
