| Abstract: | The alkali treatment conditions for multicomponent copolyester fiber were studied. The optimal base concentration, alkali treatment time and temperature and dodecyl benzyl quaternary ammonium salt (1277) concentration were discussed. The alkali treatment conditions in absence of 1277 were optimized as followed: NaOH mass fraction 3.0% , bath ratio 1 : 40, alkali treatment temperature 90℃ and time 60 min. And the NaOH mass fraction was changed to 2. 0% and bath ratio and the treatment temperature and time remained unchanged when the concentration of 1277 was 0.40 g/L. |
