Abstract

The invention relates to polyester / spandex-coated yarn with fragrance, which is made of polyester slices and additives, and is prepared according to the following steps: firstly, preparing fine denier polyester POY (pre-oriented yarn), and secondly, preparing the polyester / spandex-coated yarn by taking naked spandex filaments as heart yarn and taking the fine denier polyester POY as surface yarn according to an ATY (Airjet Textured Yarn) technology. The coated yarn prepared according to the invention feels and looks excellent when used for producing woven fabric or knitted fabric, and is wonderful in color mixing effect during dyeing.

Description

technical field [0001] The invention belongs to the field of spinning materials, in particular to a polyester / spandex covered yarn. 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 esters, fibers made by spinning and post-pro...
