Polyaluminum Chloride in Textile Printing and Dyeing

Polyaluminum chloride (PAC) has a wide range of applications in the textile printing and dyeing industry, its main functions and characteristics are as follows:

1. The main role

①Improve dye adhesion and color fastness:

Polyaluminum chloride can be used together with other agents to enhance the adhesion and color fastness of dyes in the textile printing and dyeing process to ensure that the printing and dyeing products are bright and durable.

②Adjust pH value:

Polyaluminum chloride can effectively adjust the pH value of printing and dyeing wastewater to prevent color deviation and ensure the quality of printing and dyeing products.

③Wastewater treatment:

Textile printing and dyeing wastewater is difficult to treat because of its large amount of water, deep color and high content of organic pollutants. As a flocculant, polyaluminum chloride can form solid and large alum flowers in the process of printing and dyeing wastewater treatment, the settlement rate is fast, and the treatment effect is remarkable. It helps to remove suspended substances, colloidal substances, organic pollutants, etc., in the wastewater, so that the wastewater can meet the discharge standards or reuse requirements.

2. Characteristics

①The water purification effect is obvious:

Polyaluminum chloride shows excellent water purification effect in textile printing and dyeing wastewater treatment, which can quickly make the impurities in the wastewater form floc and precipitate, and realize the separation of water and impurities.

②Strong adaptability:

Polyaluminum chloride is not affected by the quality of printing and dyeing wastewater and has a wide range of adaptability. It can play a good flocculation effect in different pH values and is suitable for the treatment of various printing and dyeing wastewater.

③Easy to operate:

The operation is simple and convenient when using polyaluminum chloride for wastewater treatment. Simply add the agent to the wastewater and stir it evenly, without complex equipment and processes.

④Green environmental protection:

Polyaluminum chloride is a kind of non-toxic and harmless water-soluble inorganic polymer flocculant, which has no pollution to the environment. Using it for wastewater treatment not only meets environmental protection requirements but also helps to protect the ecological environment.

3. Use method

  When using polyaluminum chloride in the textile printing and dyeing industry, it is usually necessary to determine the dosage and dosage method of the reagent according to the actual situation of the wastewater. In general, polyaluminum chloride can be added to the wastewater after dissolution in proportion, and fully stirred to ensure that the agent and the wastewater are in full contact and reaction. At the same time, it is necessary to pay attention to the control of the pH value and temperature of the wastewater to improve the treatment effect.

  In summary, polyaluminum chloride has a wide application prospect and remarkable treatment effect in the textile printing and dyeing industry. By using it, it can not only improve the quality and color fastness of printing and dyeing products but also effectively treat printing and dyeing wastewater and protect the ecological environment.
