- Dispersant: Sodium tripolyphosphate is used as a dispersant in the textile dyeing process to help the dye disperse evenly in the dye solution and prevent the dye from gathering.
- Stabilizer: Stabilizes the pH value of the dyeing solution to ensure the stability of the dyeing process and improve the uniformity of dyeing.
- Chelating agent: combined with calcium and magnesium ions in water to prevent these ions from reacting with dyes, affecting the dyeing effect.
- Improve the bleaching effect: sodium tripolyphosphate is used as an assistant in the textile bleaching process to enhance the effect of bleach and improve the whiteness of the fabric.
- Prevent fiber damage: By stabilizing the pH of the bleaching solution, reduce the damage of the bleach agent to the fiber.
- Softening fibers: Sodium tripolyphosphate can soften fibers and improve the feel and softness of fabrics.
- Antistatic treatment: In the fiber treatment process, sodium tripolyphosphate can reduce the generation of static electricity and improve the comfort of the fabric.
- Washing aid: In the textile washing process, sodium tripolyphosphate is used as a washing aid to enhance the decontamination ability of detergent and soften water quality.
- Prevent stain redeposition: By chelating metal ions in the water, prevent stain redeposition on the fabric.
