| titleOfInvention | Full-dull terylene pre-oriented yarn and preparation method thereof |
| abstract | The invention relates to a full-dull terylene pre-oriented yarn and a preparation method thereof, wherein the preparation method comprises the following steps: according to the POY process, modified polyester POY yarns, namely full-dull polyester pre-oriented yarns, are prepared from a modified polyester melt, and the preparation method of the modified polyester comprises the following steps: uniformly mixing terephthalic acid, ethylene glycol, 2,5,6, 6-tetramethyl-2, 5-heptanediol, fluorine-containing dibasic acid, dibasic acid with a tert-butyl side group, main chain silicon-containing dibasic alcohol, a delustering agent and high-temperature roasted multiphase solid acid-base powder, and then carrying out esterification reaction and polycondensation reaction in sequence; the multiphase solid acid-base is SiO 2 βAl 2 O 3 And/or SiO 2 -MgO. The dye uptake of the prepared product at the temperature of 125 β is 88.3-91.7%, and the intrinsic viscosity of the product is reduced by 16-20% after the product is placed for 60 months at the temperature of 25 β and the relative humidity of 65%. The method has simple process, and the prepared product has good dyeing property and natural degradation property. |
