Description

Vat Orange 20 is a high-performance vat dye belonging to the anthraquinone chemical class, known for its excellent color fastness and stability. This compound is critical for achieving durable and vibrant orange hues on cellulosic fibers like cotton and viscose. It is primarily sought after by manufacturers in the textile dyeing and printing industries, as well as for specialized applications in leather and paper coloration where superior light and wash fastness are required.

Application

• Textile Dyeing: Primary application for dyeing cotton, linen, and other cellulosic fibers to achieve fast orange shades.
• Textile Printing: Used in printing pastes for creating sharp, durable orange patterns on fabrics.
• Leather Coloring: Imparts stable and fade-resistant orange colors to finished leather goods.
• Paper Staining: Employed for coloring specialty papers where color permanence is important.
• Industrial Pigmentation: Can be used as a colorant for certain plastics and coatings requiring vat dye properties.
• Research & Development: Serves as a standard or intermediate in chemical research and dye synthesis studies.
