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 ℃, 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 ℃), dyeing time(20-60 min), dye contents(2-10 %omf), dispersant contents(1-9 g/ℓ), pH buffer solution contents(1-9 g/ℓ), 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/ℓ, the pH buffer solution contents of 1 g/ℓ, the UV-absorbent contents of 10 %omf, the dyeing temperature of 135 ℃ 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.
