| titleOfInvention | Degradable polyester fiber and preparation method thereof |
| abstract | The invention relates to a degradable polyester fiber and a preparation method thereof. The preparation method is as follows: according to the FDY process, the modified polyester FDY yarn is prepared from the modified polyester melt, that is, the degradable polyester fiber is obtained; The molecular chain of ester includes terephthalic acid segment, ethylene glycol segment, 2,5,6,6-tetramethyl-2,5-heptanediol segment and fluorine-containing dibasic acid segment; fluorine-containing The dibasic acid is 2,2-difluoro-1,3-malonic acid, 2,2-difluoro-1,4-succinic acid, 2,2-difluoro-1,5-glutaric acid or 2,2-difluoro-1,5-glutaric acid ,2,3,3-tetrafluoro-1,4-succinic acid; the modified polyester is dispersed with doped modified ZrO 2 powder. After the prepared product was placed for 60 months under the conditions of temperature of 25° C. and relative humidity of 65%, its intrinsic viscosity decreased by 23-28%. The preparation method of the invention has the advantages of low cost and simple process; the prepared product has fast natural degradation rate and great application prospect. |
