Description

technical field [0001] The invention relates to a chemical fiber-grade synthetic polyester (PET) resin with various health care functions such as negative ions, far infrared, antibacterial, and electromagnetic wave absorption and a manufacturing method thereof. Background technique [0002] The existing PET resins for chemical fiber grades with negative ion functions on the market are generally made of micro-nano negative ion functional powders, which are blended with ordinary fiber PET resins in a certain proportion after activation treatment, and the functional PET matrix is ​​prepared under certain temperature conditions. Then the masterbatch is blended with ordinary fiber-grade PET resin, melted, extruded and spun. Adopt above-mentioned method to make negative ion functional chemical fiber to have the defect of following three respects at least: [0003] 1. At the melting point of 265°C, the molecular weight of PET resin is reduced twice, which affects the structure and...
