摘要 |
Dimethyl terephthalate 10wt%, ethyleneglycol 70wt%, 2,2-bis-[4-(2-hydroxyethoxy)phenol propane 16.5wt%, 2,6-naphthalendicarbonic acid 7.5wt%, acetate 0.083wt%, antimony trioxide 0.038wt%, etc. are added to give the objective chip containing original viscosity 0.67 that is provided through the condensation polymer reaction for three hours at 260-265 degree C, the final inner temperature. This chip is melted, spun at the temperature 270 degree C to obtain the undrawn yarn, then dipped in an organic solvent composed of alkylpospate salt and polyoxyethyleneamideter component.
