It is widely used in the dyeing of polyester fibers, such as polyester filament, polyester staple fiber, etc.

  
  

• Blended fabric dyeing: In the dyeing of multi-component fibers such as cotton-polyester blended fabrics, it can coordinate the adsorption properties of different fibers to dyes, make the dyes evenly distributed on various fibers, avoid color difference and uneven dyeing, and ensure the overall dyeing effect of blended fabrics. It is suitable for the dyeing of various blended fabrics such as cotton-polyester, polyester-cotton, and polyester-nylon.

• Printing process: In the textile printing process, Dispersing Agents for Dyes can be used as an additive to the printing paste to improve the rheological properties and stability of the printing paste, making the printed pattern clearer and more delicate, with high color reproduction, while enhancing the fastness of the printing to prevent the printing from fading or blurring during washing. It is suitable for a variety of printing processes such as reactive printing and disperse printing.

  
  

• Leather dyeing: In the field of leather processing, this dispersant can be combined with leather dyes to improve the dispersion effect of dyes on the leather surface, making the leather dyeing more uniform and natural in color, improving the dyeing quality and appearance quality of leather, and is suitable for the dyeing of various leather products, such as shoe upper leather, clothing leather, etc.

  
  

• Paper dyeing: In the paper production process, Dispersing Agents for Dyes can be used for paper dyeing, which can make the dye evenly distributed in the paper fiber, improve the color uniformity and tone stability of the paper, and enhance the beauty and practicality of the paper. It is suitable for the production of various colored papers, wrapping papers, decorative papers, etc.

Dispersing Agents for Dyes Maintenance

1. Storage environment control: Dispersing Agents for Dyes should be stored in a cool, dry, well-ventilated environment, avoiding direct sunlight and high temperature. The ideal storage temperature range is 5℃-30℃, and the relative humidity should be controlled at 40%-60%. Such an environment can prevent the effective ingredients in the dispersant from decomposing or deteriorating, ensuring its stable performance. At the same time, it should avoid contact with highly corrosive substances such as acids and alkalis to avoid chemical reactions that affect product quality.

   
   

2. Container sealing inspection: Regularly check whether the packaging container of the dispersant is well sealed to ensure that it is not invaded by external air, moisture, etc. during storage. If the packaging is found to be damaged or not tightly sealed, it should be replaced or resealed in time. Generally, a comprehensive container sealing inspection is carried out at least once a month to ensure that the quality of the dispersant is not affected.

   
   

3. Precise control of usage: During use, the amount of dispersant should be accurately added in strict accordance with the product instructions or process requirements. Excessive addition will not only cause waste, but may also cause problems such as excessive dye dispersion and increased foam during dyeing; insufficient addition will affect the dispersion effect of the dye and cause uneven dyeing. Generally, during the dyeing process, the amount of dispersant added should be controlled at 5%-15% of the amount of dye, and the specific amount needs to be adjusted according to the actual situation.

   
   

4. Mixing uniformity guarantee: When mixing the dispersant with the dye, ensure that the two are fully mixed and uniform. High-speed mixers and other equipment can be used for stirring. The stirring time is generally not less than 10 minutes, and the stirring speed is controlled at 800-1000 rpm. This allows the dispersant to fully contact the dye, forming a stable dispersion system, and improving the dispersion effect and dyeing quality of the dye.

   
   

5. Regular performance testing: In order to ensure the stability of the performance of the dispersant during use, it should be regularly tested for performance. The test items include key indicators such as dispersibility, stability, and adsorption. Generally, a comprehensive performance test is carried out at least once a quarter. If the performance is found to be degraded, the cause should be analyzed in time and corresponding measures should be taken, such as adjusting the usage, replacing the product, etc., to ensure the smooth progress of the dyeing process.

   
   

6. Cleaning and maintenance after use: After each use of the dispersant, the dyeing equipment and tools should be cleaned in time to prevent the residual dispersant and dye from drying and agglomerating on the surface of the equipment, affecting the effect of the next use. When cleaning, you can use warm water and an appropriate amount of detergent to clean it. After cleaning, the equipment should be air-dried or wiped dry for the next use. At the same time, for dispersants that have not been used for a long time, a small sample test should be carried out first to confirm that its performance is qualified before large-scale use.
