Description

Reactive Red 36 is a high-performance, water-soluble azo dye belonging to the reactive dye class, specifically engineered for covalent bonding with cellulosic fibers. Its primary value lies in delivering brilliant, wash-fast red shades with excellent reproducibility and cost-effectiveness in industrial dyeing processes. This product is essential for textile manufacturers, particularly those working with cotton, viscose, and other natural fibers, who require durable and vibrant coloration. The compound is supplied as a high-purity powder to ensure consistent batch-to-batch performance in demanding production environments.

Application

• Textile Dyeing: Primary application for the exhaust and continuous dyeing of cotton, linen, hemp, and other cellulosic fabrics to achieve bright red hues.
• Yarn Dyeing: Used for dyeing cellulosic yarns in package, beam, or hank dyeing machines, ensuring deep and level penetration.
• Garment Dyeing: Suitable for the batch dyeing of finished cotton garments, offering good fabric handle and color fastness properties.
• Union Dyeing: Effective in dyeing blends of cotton with polyester or other synthetic fibers where a uniform shade on the cellulosic component is desired.
• Industrial Colorant: Potential use as a colorant for paper pulp or in the formulation of inks where reactive properties are beneficial.
