Acid Red 97 is a milling-type acid dye known for its very good wet fastness properties, making it a good choice for dyeing textiles that need frequent laundering. It produces a rich, bluish-red shade on wool, silk, and nylon. As a disazo dye, its larger molecular structure contributes to its enhanced wash fastness. It is a reliable colourant for producing durable, deep red shades in high-quality knitwear, apparel, and yarn.
