Why is the highest temperature of disperse dyeing at 130℃ (high temperature and high pressure method)

Because at 130 ℃, the dyeing percentage of disperse dyes is the highest, with bright color, level dyeing and less floating color.

1) If the temperature is too high, the dye is easily decomposed and the fiber is easily damaged.

2) If the temperature is too low, the dyeing rate is low and the dye penetration is poor. Therefore, the maximum suitable temperature for disperse dyes is 130 °C.
