[0002] China is a major textile manufacturing country, accounting for 36% of the global output. In the textile industry, dyeing textiles is an essential process, and all textiles need to undergo dyeing treatment. However, traditional dyeing processes cause great pollution to the environment and consume a large amount of energy.

[0003] However, by spraying dye on textiles, using an inkjet print head to spray ink with colors onto textiles, compared with traditional dyeing methods, less wastewater is generated, which is more energy-saving and environmentally friendly. However, it is necessary to ensure that the material of the inkjet print head is compatible with the physical and chemical properties of the ink. Since the types of inks that the inkjet print head can adapt to are limited, to achieve printing in multiple colors, multiple inkjet print heads need to cooperate with each other, and the corresponding ink supply system becomes more complex.
