Water-based dyes are a class of dyes that dissolve in water and are commonly used to color fibers, paper, leather, and other materials. Water-based dyes are soluble in water, non-toxic, low volatility and good color fastness. In order to solve the problem of easy blistering,Water-based dye defoamerwas introduced into it.
There are several reasons and functions in the addition of water-based dye defoamers in formulations:
1.Controlling bubble generation: In the preparation of aqueous dyes, bubbles are often generated due to the characteristics of the material or the conditions of the production process. These bubbles can come from the mixing process of water, the reaction of raw materials to produce gases, or the adsorption of air on the surface of the material. The addition of defoamer can effectively control the formation and expansion of air bubbles and avoid the accumulation of air bubbles in the dye.
2.Improved dye transferability and homogeneity: Aqueous dyes need to be deposited and penetrated evenly on the surface of fibers or other materials to achieve the desired dyeing results. However, the presence of air bubbles can create barriers during coating or soaking, affecting the transfer and uniformity of the dye. By adding a defoamer, the surface tension of the bubbles can be broken, the bubbles can be removed, and the dye can be in better contact with the surface of the material for a more uniform coloring effect.
3.Improve dye permeability: The addition of defoamers can improve the permeability of water-based dyes. Because isolated air bubbles can cause the dye to not penetrate effectively inside the fiber or material as it goes through the dyeing process. Through the action of the defoamer, the generation of bubbles can be reduced, and the contact area between the dye and the material can be increased, thereby improving the permeation performance of the dye.
Water-based dye defoamerThe principle of action is mainly to prevent the formation of bubbles by reducing the surface tension of the liquid during the preparation or stirring of the dye. This helps to reduce gas absorption and foam formation, improving the stability and quality of the dye.
