Sodium phosphates, including TSP, MSP, DSP, and STPP, are chemicals that help in textile dyeing by controlling pH levels and preparing fabrics for better dye absorption. They play an essential role in textile dyeing for pH control, alkalinity provision, and scouring enhancement. Sodium phosphates are used in processes like acid dyeing, reactive dyeing, and bleaching, ensuring consistent and high-quality results. They offer significant advantages in terms of dyeing uniformity, productivity, and process efficiency, with well-defined working mechanisms that support their widespread use.
