Abstract

The invention relates to a polyester / spandex coated yarn with a far infrared function. The polyester / spandex coated yarn is made by steps of using polyester chips and additives as raw materials, preparing a fine-denier polyester POY (pre-oriented yarn), using a naked spandex filament yarn as a core yarn and using the fine-denier polyester POY as a skin yarn to prepare the polyester / spandex coated yarn by means of the ATY (air-jet texturing yarn) process. The polyester / spandex coated yarn has excellent handfeel and appearance when being used for production of woven fabrics or knitted fabrics and has excellent mixed color effects in dyeing.

Description

technical field [0001] The invention belongs to the field of spinning materials, and in particular relates to a polyester / spandex coated yarn prepared by a POY-ATY process. 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] Polyester fiber is a fiber-forming high polymer made of terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification followed by polycondensation reaction - polyethylene terephthalate Alcohol est...
