Description

Reactive Violet 12 is a high-purity, reactive dye belonging to the vinyl sulfone class, known for its excellent color fastness and brilliant violet hue. This compound is critical for achieving durable and vibrant coloration on cellulosic fibers like cotton and viscose. It is primarily used by textile manufacturers and dye houses seeking reliable, wash-fast dyes for industrial fabric production.

Application

  • Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, rayon, and other cellulosic fibers.
  • Garment Manufacturing: Used for dyeing finished apparel, home textiles, and denim to achieve a uniform violet shade.
  • Industrial Fabric Production: Coloration of canvas, toweling, and other heavy-duty fabrics requiring high wash and light fastness.
  • Yarn Dyeing: Suitable for dyeing cotton and blended yarns in hank or package form for weaving and knitting.
  • Technical Textiles: Potential use in dyeing non-woven and technical fabrics where color consistency is paramount.
