Water quality plays a critical role in textile processing. The presence of hardness ions such as Ca²⁺, Mg²⁺, Fe²⁺, and Fe³⁺ can significantly impact pretreatment, dyeing, and finishing performance. Sequestering agents are specialized chelating compounds designed to complex metal ions and keep them in soluble form, preventing unwanted reactions during processing. Why Are Sequestering Agents Important? ✔ Prevent precipitation of calcium and magnesium salts ✔ Improve stability o
