Uses

Tracid Brilliant Red 10b is widely used for dyeing wool, silk, nylon, and blended fabrics. It is suitable for dyeing loose wool fibers, tops, and skeins, producing a rich, bluish hue. It exhibits good wet fastness and felting properties, but poor light fastness (grade 4). It is also used for silk dyeing and direct printing on wool, silk, nylon, and viscose fiber fabrics. When used for dyeing wool/viscose fabrics, it can be used in the same bath as direct dyes; post-dyeing treatment with a fixing agent can improve wet fastness. Besides being used alone, it is also used for color mixing.
