The reason for the color flower after dyeing by the automatic dyeing machine

1. Process formulation and operation issues:
If the process is unreasonable or the operation is improper, color flowers will occur, the process is unreasonable (such as the temperature rises and falls too fast), the operation is poor, the node is knotted during dyeing, the power is cut off during dyeing, the temperature rises too fast, and the holding time is insufficient, etc.
2. Equipment failure problem:
For example, after dyeing polyester with disperse dyes, even if the temperature in the oven is inconsistent, it is easy to produce color flowers, too much dyed cloth, too long, and slow running speed of the dyeing machine.
3. Raw material problem:
Insufficient uniformity of fiber raw materials and fabric organization.
4. Dye problem:
Dyes are easy to agglutinate, have poor solubility, are too sensitive to temperature and pH, and are prone to color flowers.
5. Water quality problems:
The water quality is not good, resulting in color flower caused by combination of dye and metal ion or condensation of dye and impurity, light color without sample attachment and so on.
6. Auxiliary problems:
Among the inappropriate dosage of auxiliaries, the auxiliaries related to colored flowers mainly include penetrating agent, leveling agent, chelating dispersant, pH value control agent, etc.
