Description

technical field [0001] The present application relates to the field of polyester fibers, in particular to an electromagnetic shielding far-infrared polyester fiber. Background technique [0002] Polyester fiber, also known as polyester, is an important type of synthetic fiber. It is a fiber obtained by esterification or transesterification and polycondensation reactions using terephthalic acid or dimethyl terephthalate and ethylene glycol as raw materials. High polymer - polyethylene terephthalate (PET), fiber made by spinning and post-processing. Its cost is low, and it has the advantages of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, etc., but there are problems such as single product and low technical content. Therefore, high-performance and functional polyester fiber is the focus of its future development. . Contents of the invention [0003] The present invention aims to provide an electromagnetic shielding far-infrared...
