METHOD AND DEVICE FOR THE CONTINUOUS POLYCONDENSATION OF POLYESTER MATERIAL IN THE SOLID PHASE |
摘要 |
The invention relates to a method and device for the continuous polycondensation of polyester material in the solid phase, in particular in the form of partially crystalline granulate. The aim of the invention is to achieve a high product throughput on recrystallising and recondensation of polyester material with a low initial IV. Said aim is achieved, whereby on recrystallisation, a low residence time of 1-10 minutes is achieved, by means of a rapid heating of a thin product layer, followed by an SSP treatment.
