Description

C.I. Reactive Red 26 is a high-performance, water-soluble reactive dye belonging to the azo chemical class. It is engineered to form a strong covalent bond with cellulosic fibers, ensuring excellent wash and light fastness properties for vibrant, durable coloration. This product is essential for textile manufacturers and dye houses seeking reliable and efficient red shades for cotton, viscose, and other natural fabrics. Its consistent quality makes it suitable for demanding industrial dyeing and printing applications.

Application

• Exhaust Dyeing of Cellulosic Fibers: Primary application for dyeing cotton, rayon, linen, and hemp in batch processes.
• Continuous Dyeing: Used in pad-steam and pad-batch processes for uniform coloration of woven and knitted fabrics.
• Textile Printing: Formulated for screen and rotary printing inks to create sharp, vivid red patterns on fabrics.
• Yarn Dyeing: Suitable for dyeing cotton and viscose yarns in hank, package, or beam dyeing machines.
• Garment Dyeing: Applied for dyeing finished apparel items to achieve consistent and fashionable red tones.
• Leather Coloration: Used in the dyeing of certain types of leather where reactive dyes are applicable.

Quality Control

Our production of C.I. Reactive Red 26 adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including color strength, shade, solubility, and fixation properties. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and application performance is provided with each shipment to support your quality assurance processes.

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). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from incompatible materials.
