| description | The invention relates to a production method of a bright cross-shaped polyester drawn yarn, which comprises the following steps of: extruding a polyester melt from a spinneret plate with cross-shaped special-shaped spinneret orifices, and sequentially carrying out cooling forming, primary oiling, pre-interlacing, drawing and sizing, secondary oiling, main interlacing and winding forming to obtain the bright cross-shaped polyester drawn yarn, a hot roller adopted for drafting and shaping is a hot roller with a groove, the groove is a continuous groove, and the groove is spirally distributed on the peripheral surface of the hot roller. According to the invention, the smooth structure of the mirror surface of the hot roller is designed into a circle of grooves which are spirally distributed, and the contact area between fibers and the surface of the hot roller is increased by utilizing the design of the grooves, so that the heating area is increased, the shaking of tows on the hot roller is reduced, the fibers a |
