In polyester production and processing, the oil agent is an extremely important auxiliary agent, and is an essential important textile auxiliary agent in the spinning process particularly when POY and DTY polyester filaments are spun. Because the polyester fiber does not have the natural colloid and softness of the natural fiber, has poor hygroscopicity and no conductivity, the natural colloid can play the roles of static resistance, bundling and moisture absorption unlike the natural fiber in the spinning process, so that the fiber has good smoothness. The spinning oil agent is an important reagent for fiber post-processing, can increase the holding force of the polyester fiber in the processing process, reduce the friction coefficient between the fiber and machinery, reduce the generation of static electricity, and achieve the same easy processing property as natural fiber.
