Acid Red 359 is a water-soluble acid dye designed to deliver bright, durable red shades on protein fibers (wool, silk) and polyamide (nylon). It combines high tinting strength and excellent exhaustion with reliable reproducibility across batch dyeing and continuous processes.

When properly exhausted and rinsed, Acid Red 359 provides good washfastness on wool and nylon and moderate to good lightfastness. Fastness will improve with optimal fixation and suitable after-treatments specific to the end use (e.g., washing, leveling agents or UV stabilizers for outdoor uses).
Acid Red 359 is optimized for protein fibers such as wool and silk and for polyamide fibers like nylon. It gives its best combination of color yield and fastness on these substrates; performance on cellulose (cotton) is limited unless used with a suitable binder or after-treatment.
Dissolve the dye completely in warm water before adding to the dye bath to avoid local overdosing. For industrial practice, prepare a concentrated stock solution at moderate temperature, filter if necessary, and add gradually under good circulation to the main bath.
Handle Acid Red 359 with appropriate PPE (gloves, eye protection, dust mask for powders). Follow local wastewater regulations: remove unfixed dye by conventional wastewater treatment or dye recovery methods before discharge. Consult the product SDS for detailed hazard, handling and disposal instructions.
