1) Heating requirements:
Control the temperature rise, otherwise the temperature rises too fast, which will cause the dye to be dyed too fast, resulting in chromatic aberration.
① Colored flowers: refers to the uneven dyeing and dyeing.
② The purpose of heat preservation in the middle (90℃*5') is to make the dye evenly absorbed by the fiber and then heat up to prevent the color flower.
③ Heating rate: should be slow, generally controlled at 1~2℃/min
2) Cooling requirements:
① Requirements: Naturally cool down below 80°C after dyeing (generally controlled at 1~2°C/min)
② If the temperature drops suddenly after dyeing, it is easy to appear chicken paw prints (wrinkles) or make the fabric feel rough.
③ General operation:
After cooling down to 80°C at 2°C/min, wash with water. It is strictly forbidden to open the lid and wash with water above 80°C, otherwise safety problems may occur.
