| Abstract: | The investigation was related to recycling waste polyester fiber.Oilless waste polyester fiber took the glycolysis reaction with glycol under the catalyst of Zn（AC）2,at 220 ℃.Then the product was filtrated in order to remove unreacted impurities.Ploycondensation reaction was conducted by adding a certain amount of glycolytic product and the uniform polyester chips were obtained.The results showed that the additon of the glycolytic product was less than 0.2 %,the performance index of polyester chips reached the standard of fiber grade. |

| Keywords: | waste polyester fiber glycolysis polyester chip ploycondensation recycle and reuse |
