Abstract

The invention relates to a method for producing a fine-denier glazed super-black terylene FDY (Fully Drawn Yarn) filament yarn. The method comprises the following steps of (a) weighing 92%-94% of glazed PET (Polyethylene terephthalate) slices and weighing 6% of black master-batches to dry; (b) blending the dried glazed PET slices with the dried black master-batches, and putting the mixture into a screw extruder so as to form PET flux; (c) filtering and pressurizing the PET flux, and distributing the pressurized PET flux to all spinneret components for producing nascent fibers through a metering pump; (d) winding-forming the nascent fibers by means of cooling the nascent fibers through side blowing, oiling the nascent fibers through an oil nozzle, performing stretching-setting operation on the nascent fibers, and gridding the nascent fibers, wherein the speed of a first heat roller for the stretching-setting operation is 1,500-2,000 m / min, and the temperature of the first heat roller is 80-90 DEG C; the speed of a second heat roller is 4,000-4,500 m / min, and the temperature of the second heat roller is 120-130 DEG C; the winding speed is 4,000-4,500 m / min, and the winding tension is controlled to be 10-15 N. According to the method for producing the fine-denier glazed super-black terylene FDY filament yarn, on one hand, the glazed PET slices and the black master-batches are blended and prepared into the PET flux, so that the PET flux can be used for preparing the glazed super-black terylene FDY filament yarns; on the other hand, the prepared filament yarns are fine-denier yarns by means of adjusting the speeds of the first heat roller and the second heat roller as well as the winding speed.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, relates to a polyester FDY filament, in particular to a production method of a fine denier glossy ultra-black polyester FDY filament. Background technique [0002] Polyester fabrics are closely related to people's lives and are closely connected. They are used for clothing, bedding, decorations, bags, tents, etc. Polyester FDY (full name Fully Drawn Yarn, fully drawn yarn) introduces stretching in the spinning process, and can obtain winding yarn with high degree of orientation and medium crystallinity. Polyester FDY fabric feels smooth and soft, and is often used to weave imitation silk fabrics. The existing white polyester FDY filament cannot meet people's daily needs to a certain extent, so it needs to be improved. Extra black FDY filament is a special modified fiber, which is made by adding black masterbatch on the basis of the original FDY white silk, and processed through a certai...
