Applications of 33203-82-6

Industry Application Process
Textile dyeing and printing industry Dyeing of acrylic (polyacrylonitrile) fibers and their blended fabrics Exhaust dyeing: Dye uptake via ionic bonding in an acidic bath (pH 4–5), followed by temperature ramping and holding; Pad dyeing: Suitable for continuous pad dyeing or jigger dyeing.
Textile dyeing and printing industry Direct printing on acrylic fiber fabrics Printing paste preparation: Dissolve dye and incorporate into printing thickener; fixation via atmospheric steaming, followed by rinsing and soaping.
Papermaking industry Tinting and dyeing of cultural paper, decorative paper, and specialty papers Wet-end dyeing: Direct addition to pulp suspension, leveraging cationic groups to bind with negatively charged fibers; Surface dyeing: Applied via coating or impregnation of paper surfaces.
Leather industry Dyeing of leather, particularly chrome-tanned leather Post-tanning dyeing: Conducted under acidic conditions, where dye cations bind to anionic sites in leather to enhance color appearance.
Chemical industry Raw material for preparing compound dyes Compounding process: Blended with other dye classes (e.g., acid dyes) to formulate one-bath dyeing auxiliaries.
