Abstract:
With the method of adding dyeing carrier of disperse dyes for polyester - benzyl alcohol to alkali deweighting treatment bath of polyester, this paper studies the influence of technological factors such as dosage of benzyl alcohol, sodium hydroxide and cationic accelerant and temperature and time of alkali deweighting on the effect of alkali deweighting of polyester, tests weight loss ratio of polyester fabric subject to alkali deweighting and uses scanning electron microscope for observation. The research result shows that weight loss ratio of polyester fabric increases with the increase of dosage of benzyl alcohol, sodium hydroxide and cationic accelerant and temperature and time of alkali deweighting; the optimal process of alkali deweighting of polyester is as below: accelerant 10-10-10 1.5×10-4 mol/L, benzyl alcohol 30 mL/L, sodium hydroxide 10 g/L, treatment for 40 min at 80 ℃; weight loss ratio and strength loss of polyester fabric after treatment of alkali deweighting are respectively 21.75% and 29.54%; fiber surface is corroded after treatment of alkali deweighting
