Method for producing recycled polyester |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for efficiently chemically recycling dyed polyester fiber products to produce a stable and good quality recycled polyester. A dyed polyester fiber product is decolorized and granulated to obtain a fiber granulated product, and then the fiber granulated product is collected together with recovered polyester, glycol and alkali compound in a first batch reactor. And a depolymerization reaction is performed at 230 to 260 ° C., and the resulting low polymer is supplied to a second batch reactor and a polycondensation reaction is performed at 270 to 300 ° C. to produce a regenerated polyester. [Selection figure] None |
