Abstract |
In this study, we conducted alkali hydrolysis on sea-island type PET
ultramicrofiber tricot fabric and dyeing according to the various conditions with black
disperse dye. Herein, we evaluated the weight loss rate and tensile strength according
to the NaOH contents. The optimal alkali hydrolysis treatment conditions were set to
25 %omf NaOH with a treatment time of 60 min at 110 ¡É, and average weight loss
rate of the PET ultramicrofiber tricot fabric is about 23 %. The dyeing conditions
were investigated with different dyeing temperatures(95-135 ¡É), dyeing time(20-60
min), dye contents(2-10 %omf), dispersant contents(1-9 g/§¤), pH buffer solution
contents(1-9 g/§¤), UV-absorbent contents(5-25 %omf) and reduction cleaning process
conditions for black color. We obtained the optimum conditions of the dyeing with
the dye contents of 8 %omf, the dispersant contents of 1 g/§¤, the pH buffer solution
contents of 1 g/§¤, the UV-absorbent contents of 10 %omf, the dyeing temperature of
135 ¡É and the dyeing time of 40 min. The light colorfastness of dyed ultramicrofiber
PET tricot fabric was good to excellent in the range of 4 to 5. |
