Used for wool, polyamide, silk dyeing and printing directly, also used in leather shading.
Acid Blue 62 works exceptionally well on protein fibers like wool and silk, but it can also be applied to nylon and other synthetic fibers with proper mordanting. Its versatility allows precise shade control across multiple fabrics.
The dye exhibits excellent wash fastness and good light fastness, ensuring long-lasting vibrant colors on textiles. Its strong resistance to rubbing minimizes color transfer during garment use.
Yes, it is compatible with other acid dyes and various textile auxiliaries, allowing for custom shade blending and improved uniformity in multi-color dyeing processes.
Keep the dye in a cool, dry place away from direct sunlight. Proper storage ensures stability and preserves the dye’s performance over time.
While Acid Blue 62 is water-soluble and generally safe in standard dyeing procedures, wastewater treatment is recommended to reduce environmental impact and comply with local regulations.
