Description

Procion Yellow H-E3G is a high-performance, reactive dye belonging to the monochlorotriazine class, known for its brilliant yellow hue and excellent fastness properties. Its primary value lies in forming a stable covalent bond with cellulosic fibers, ensuring outstanding wash and light fastness for durable coloration. This product is essential for textile manufacturers, particularly those specializing in cotton, viscose, and other cellulose-based fabrics, seeking reliable and vibrant dyeing solutions.

Application

• Exhaust Dyeing of Cellulosic Fibers: Primary application for dyeing cotton, rayon, linen, and other plant-based textiles in batch processes.
• Continuous Dyeing (Pad-Batch/Pad-Steam): Used in high-volume, efficient dyeing ranges for uniform coloration of woven and knitted fabrics.
• Yarn Dyeing: Suitable for dyeing cellulose-based yarns for subsequent weaving or knitting.
• Union Dyeing: Effective for dyeing blends of cellulose with other fibers under specific conditions.
• Printing Pastes: A key component in the formulation of printing inks for textile printing applications.
• Technical Textiles: Used for coloring industrial fabrics where color consistency and durability are critical.
