Title:
FUNCTIONAL POLYESTER PRODUCTION METHOD AND PRODUCTION SYSTEM, AND FUNCTIONAL POLYESTER FIBER
Document Type and Number:
WIPO Patent Application WO/2020/133961
Kind Code:
A1
Abstract:
A functional polyester production system, which relates to the technical field of polymer material synthesis. The functional polyester production system comprises a polyester main body production system and a functional powder slurry concentrate preparation system; the polyester main body production system comprises an esterification system, a pre-polycondensation system and a final polycondensation system that are connected in sequence; the functional powder slurry concentrate preparation system comprises an online addition device that is connected to the esterification system or/and to a site between the esterification system and the pre-polycondensation system. By introducing a functional powder slurry concentrate preparation system into a polyester main body production system, a functional powder slurry concentrate having a low hydroxyl value and low pressure filtration value may be continuously prepared, and the prepared functional powder slurry concentrate and a polyester oligomer are uniformly mixed and then undergo a polycondensation reaction to obtain functional polyester in which functional powder is highly uniformly dispersed. The present invention also relates to a functional polyester production method.
