Abstract

The present invention relates to a far infrared polyester fine denier ATY. A PDY fine denier filament is prepared from raw materials comprising polyester chips and additives by a process route comprising a screw extruder, a pre-filter, a static mixer, a metering pump, a spinning assembly, flow, side blowing, oil application, a spinning shaft, a first godet, a second godet, a third godet and winding. An air texturing nozzle is employed to carry out air texturing to prepare the ATY (air textured yarn). According to the invention, a metal salt catalyst is used to change a polyester melt structure, so as to prepared the fine denier ATY with far infrared function.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to a polyester fine-denier ATY yarn produced by slicing. Background technique [0002] At present, synthetic fibers generally include polyester (polyester), nylon (polyamide), polypropylene (polypropylene), spandex (polyurethane), acrylic (polyacrylonitrile) and the like. 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 ge...
