Printing and dyeing water should be colorless, odorless, and clear. Impurities in the water often affect the quality of textile processing. For example, iron ions can make the fabric yellow, and calcium and magnesium ions may precipitate higher fatty acid salts, resulting in weakening or even loss of vitality. Calcium and magnesium ions will also precipitate the dye during the dyeing process, which will make the color of the dyed fabric dim and reduce the color fastness. Therefore, before using the printing and dyeing water, the calcium and magnesium plasma content in the water needs to be strictly controlled to ensure that the quality of the water meets the printing and dyeing requirements.
