Description

Reactive Red 242 is a high-performance, fiber-reactive dye belonging to the azo dye class, identified by CAS NO 145537-87-7. It is engineered to deliver brilliant, wash-fast red shades with excellent reproducibility and yield on cellulosic fibers. This product is essential for textile manufacturers and dye houses seeking reliable coloration for cotton, viscose, and other natural fibers. Its robust performance makes it a key component in formulations for industrial dyeing and printing processes.

Application

• Primary dyeing of cotton and viscose fibers in exhaust and continuous processes.
• Textile printing applications for producing sharp, vivid red patterns on cellulosic fabrics.
• Used in combination with other reactive dyes to achieve a broad spectrum of shades and hues.
• Formulation of specialty dye products and ink-jet inks for textile printing.
• Application in the dyeing of hemp, linen, and other natural cellulosic materials.
• Potential use in research and development for novel dyeing techniques and material science.

Quality Control

Our Reactive Red 242 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent shade, strength, and reactivity. Key parameters such as color value, solubility, and fixation rate are verified against stringent internal standards. Certificates of Analysis (COA) detailing purity and performance specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials. The product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture absorption and caking.
