| titleOfInvention | Continuous production method of copolyester |
| abstract | PROBLEM TO BE SOLVED: To provide a copolyester having excellent thermal adhesiveness to polyester fiber by adding recycled polyester to a polyester low polymer and using diethylene glycol, and capable of stably producing high quality polyester. A continuous manufacturing method is provided. SOLUTION: The method for continuously producing a copolyester according to the present invention comprises a dicarboxylic acid component and a glycol component as raw materials, an esterification reaction, and polycondensation of the obtained polyester low polymer to continuously produce a polyester. In this method, 1.0 to 2.0% by mass of diethylene glycol and 3 to 5% by mass of polyester waste are supplied to the esterification reactor with respect to the total mass of the polyester, and then a polycondensation reaction is performed. It is a continuous production method of a copolyester characterized by the fact that it is 55-0.65 dl / g. [Selection figure] None |
