INDUSTRIAL GRADE

Reactive Orange HeR

Whatsapp Order

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.

Description

 

Primary Uses

Textile Dyeing Industry
Used for dyeing cotton, viscose, lyocell, and their blends using high-exhaust methods.

Applied in package dyeing, yarn dyeing, and fabric dyeing, especially in industries requiring brilliant and durable orange shades.

Suitable for home textiles like towels, curtains, and bedsheets, as well as garments and uniforms requiring consistent coloration.

Commonly used in continuous dyeing operations for large-scale production.

Textile Printing
Employed in rotary and flatbed screen printing for bright orange designs on natural fiber fabrics.

Compatible with reactive printing pastes in multi-color designs requiring long-lasting color fastness.

Secondary Uses

Custom Shade Development
Used in formulation of reactive dye blends to create custom shades for seasonal fashion or branding requirements.

Handcraft & Artisan Textiles
Applied in small-batch and artisan dyeing, including batik and tie-dye, due to its vibrant hue and good reproducibility.

Educational and Laboratory Use
Used in academic settings for training in textile chemistry, dye performance testing, and fastness assessments.

Blended Fabrics
Can be used with auxiliaries to dye cotton-polyester or cotton-elastane blends, controlling migration and fixation.
