Preparation method and application of modified polyester stretch yarn with special-shaped section
ActiveCN103334174BGood moisture wicking effectImprove comfortFibre typesFilament/thread formingYarnFiber
The invention relates to the technical field of spinning and provides a preparation method of a modified polyester stretch yarn with a special-shaped section so as to solve the problem that polyester fiber cannot meet the requirements on excellent moisture absorption and sweat releasing properties. The preparation method comprises the following steps of: preparing alkali-soluble master batches; mixing the alkali-soluble master batches, barium sulfate subjected to surface treatment by a modifier and a dispersing agent at high speed, and pelleting the mixture by using a double-screw extruder to prepare barium sulfate-alkali-soluble master batches; and performing blended spinning on the barium sulfate-alkali-soluble master batches and polyethylene glycol terephthalate to obtain the modified polyester stretch yarn with the special-shape section. In a production process, the using efficiency of a machine platform is high and the end breakage rate is low, so the production speed of the modified polyester stretch yarn is increased, the processing cost is reduced, and the modified polyester stretch yarn can be applied to development of various high-grade fabrics.
