Abstract

The invention relates to a polyester fine-denier ATY (air-jet texturing yarn) fiber. The polyester fine-denier ATY fiber is made by steps of using polyester chips and additives as raw materials, preparing a PDY (partially drawn yarn) fine-denier filament by a process route of a screw extruder, a pre-filter, a static mixer, a metering pump, a spinning component, trickling, side blowing, oiling, a passage, a first fiber guide roll, a second fiber guide roll, a third fiber guide roll and winding, and using an air jet nozzle for air jet to prepare the ATY fiber. A polyester melt structure is modified by means of metal salt catalysts to prepare the fine-denier ATY fiber with an anti-ultraviolet function.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to a polyester fine-denier ATY fiber filament produced by slicing. Background technique [0002] At present, synthetic fibers generally include (polyester), nylon (polyamide), polypropylene (polypropylene), spandex (polyurethane), acrylic (polyacrylonitrile) and so on. These fibers have different properties and thus different uses. But at present generally take fabric, because its fiber is thicker, feel rough, softness is poor, air permeability is poor, water absorption is poor, easy to pilling. With the improvement of people's living standards, the requirements for textiles are getting higher and higher. [0003] Polyamide fiber is the earliest synthetic fiber variety put into industrial production in the world. It is made of polyamide synthesized by polycondensation reaction of aliphatic dibasic acid and diamine or aliphatic amino acid, and then melt-spun. A gener...
