Reactive Orange HeR

Reactive Orange HeR is a mono-functional, high-exhaust class reactive dye designed for dyeing and printing of cellulosic fibers, particularly cotton and viscose. It reacts covalently with hydroxyl groups on cellulose under alkaline conditions, resulting in excellent wash, light, and perspiration fastness. Known for its brilliant orange shade, Reactive Orange HeR offers high fixation efficiency, compatibility with other HE dyes, and suitability across multiple dyeing methods such as exhaust, pad-batch, and pad-dry-cure processes.
