Cationic Red 3r Basic Red 16 Dyes for Acrylic Fiber

Cationic Red 3R (C.I. Basic Red 16) offers good light fastness and excellent leveling properties on acrylic fibers. Its bright red shade with good build-up makes it suitable for both pale and deep shades, providing flexibility in color matching.

The recommended dyeing temperature is 105~110 degree. When dyeing acrylic fibers, gradually raise the temperature to the fiber's glass transition point (75~85degree), then increase slowly at 1 degree per 2~4 minutes to ensure level dyeing and prevent unevenness.

It can be used alone for bright red shades or combined with other cationic dyes to achieve deeper or modified shades. It works particularly well as the red component in trichromatic dyeing systems with compatible yellow and blue cationic dyes.

Cationic Red 3R has good compatibility with most cationic dyes used in acrylic dyeing. For trichromatic systems, it pairs well with Cationic Yellow and Cationic Blue dyes that have similar dyeing rates, ensuring consistent shade reproduction batch to batch.
