Manufacturing technique of melt direct spinning polyester activate industrial yarns

The invention discloses a manufacturing technique of melt direct spinning polyester activate industrial yarns, and specifically belongs to the field of fiber manufacturing in polyester industry. The manufacturing technique is used for rubber framework materials and comprises melt liquid tackifying, melt direct spinning, draft heat shaping and winding molding. A vertical type liquid phase tackifying reactor is used for tackifying, a spinning technique, multi-stage draft, multi-stage relaxation heat shaping, activating treatment of oil applying on an oil nozzle, and unique high speed winding of a winder are matched, and therefore yarn activation of the melt direct spinning polyester activate industrial yarns is achieved. The manufacturing technique of the melt direct spinning polyester activate industrial yarns has the advantages of being low in energy consumption, high in the rate of production, short in production cycle and the like. Manufactured activation yarns can be used for rubber framework materials such as a conveying belt, a triangle belt, canvas, ropes and the like.
