해도형 PET 극세사 트리코트 편성물의 감량 및 베이지 색상의 염색성 평가

In this study, we conducted alkali hydrolysis on a sea-island type PET tricot fabric with NaOH 25% omf at 100 oC for 30 min. After the alkali weight reduction was completed, dyeing of the sea-island type PET tricot fabric under various dyeing conditions was conducted to optimize the dyeing conditions for the color beige. The dyeing conditions were investigated across various dye contents (0.03-0.06 % omf), dyeing temperatures (100- 135 oC), dispersant contents (1-9 g/l), UV-absorbent contents (1-5 % omf), and reduction cleaning process conditions. We observed that washing, light, and rubbing colorfastness of the dyed beige-colored sea-island type PET tricot fabric was achieved for 4-5 grades.
