Problems solved by technology

[0009] The current far-infrared fiber is mainly of the post-processing type. The post-finishing process is generally to disperse the far-infrared powder in the liquid, and then attach it to the surface of the polyester fiber through a coupling agent. This product has many defects: first, because the surface Coating active ingredients are limited, resulting in low far-infrared generation; secondly, poor durability and washing resistance; finishing processing also increases the uncertainty of the use of post-spinning auxiliaries

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to a far-infrared polyester fiber and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET), also known as polyester (Polyethyene terephthalate), is a polymer compound that is prepared by polycondensation of terephthalic acid (PTA) and ethylene glycol (EG). The technology of PET polyester spinning is known and common polyester fibers are abundantly available on the market. With the gradual improvement of people's living standards, the public's requirements for the quality of life are also gradually improved. It is in this case that the function of far infrared health care is gradually known to the public. [0003] Far-infrared rays are called "the light of life" in the medical field, and their main functions are as follows: [0004] 1. Ray massage activates the activity of skin macromolecules, restores functional balance...
