Description

Reactive Red 136 is a high-performance, fiber-reactive dye belonging to the azo dye class, specifically engineered for covalent bonding with cellulosic substrates. 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 specializing in cotton, viscose, and other cellulose-based fabrics, seeking reliable and vibrant coloration.

Application

• Exhaust Dyeing of Cellulose: Primary application for dyeing cotton, rayon, linen, and other cellulosic fibers in jet, overflow, and winch dyeing machines.
• Continuous Dyeing Processes: Used in pad-batch, pad-steam, and pad-dry thermofix processes for uniform and efficient fabric coloration.
• Textile Printing: Formulated for use in printing pastes to create sharp, durable red patterns and designs on cellulosic textiles.
• Leather Dyeing: Employed to impart rich red colors to leather goods, offering good penetration and fastness properties.
• Paper Coloration: Suitable for specialty paper grades requiring a stable and bright red hue.
• Biomaterial Staining: Potential use in laboratory settings for histological staining due to its reactive nature and color properties.

Quality Control

Our Reactive Red 136 is manufactured under a stringent quality management system. Every batch is tested to ensure consistent shade, reactivity, and fastness properties, with key parameters including strength, solubility, and fixation rate monitored against internal standards. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and application performance is provided with each shipment to guarantee it meets the specific demands of industrial dyeing processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Keep away from strong oxidizing agents and excessive heat. The product is hygroscopic (moisture-sensitive); ensure the original packaging is resealed tightly after use to prevent moisture absorption and caking.
