Key Benefits Of
TANACID UNA
Deep Neutralisation
Reaches and neutralizes leftover alkali inside the fibres-more effectively than commonly used acids like acetic or formic. This ensures your fabric is fully prepared for the next steps.
Brighter Whites
Improves the appearance of bleached cellulosic fabrics, especially linen, by enhancing their brightness and creating a cleaner, more refined finish.
Process Stability
Keeps pH levels stable during both bath and continuous processing, which helps improve dye uniformity and ensures reliable results in finishing steps like resin treatment.
Eco-Friendly Formula
Easily biodegradable and has a lower environmental impact (COD) than traditional neutralizers like acetic acid-compliant with Ökotex safety standards.
Reliable Under Pressure
Performs consistently even in tough conditions like low pH, short wash cycles, high-acid formulas, or heavily loaded systems—ensuring smooth and efficient processing when it matters most.
