Problems solved by technology

[0003] 1. At the melting point of 265°C, the molecular weight of PET resin is reduced twice, which affects the structure and strength of the material;
[0004] 2. The agglomeration phenomenon due to the high surface energy of the micro-nano functional powder often leads to uneven mixing of the functional powder and resin system, resulting in crystal points and agglomerated particles, making the filter easy to block and affecting spinning;
[0005] 3. Part of the micro-nano functional powder is blocked on the filter screen, resulting in a decline in the function of the fiber and affecting the filament rate

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...
