Description

Procion Brilliant Red M5Bs is a highly reactive, water-soluble azo dye belonging to the Procion MX series of fiber-reactive dyes. This compound is valued for its brilliant red hue and excellent colorfastness properties, particularly on cellulosic fibers like cotton and viscose. It is primarily used by manufacturers in the textile industry for dyeing and printing applications, where consistent color yield and wash-fastness are critical commercial requirements. Its reactive nature allows for strong covalent bonds with the fabric, ensuring vibrant and durable coloration.

Application

• Textile Dyeing: Primary application for dyeing cotton, linen, rayon, and other cellulosic fibers in exhaust and continuous dyeing processes.
• Textile Printing: Used in screen printing and rotary printing of fabrics to achieve bright, sharp red shades.
• Garment Dyeing: Suitable for batch dyeing of finished apparel items, offering good penetration and leveling.
• Yarn Dyeing: Applied for dyeing cellulosic yarns in hank, package, or beam forms for weaving and knitting.
• Research & Development: Serves as a reference standard or active component in R&D for developing new dye formulations and processes.
• Educational Use: Utilized in academic and industrial training settings to demonstrate reactive dye chemistry and application techniques.

Quality Control

Our Procion Brilliant Red M5Bs is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including color strength, hue, solubility, and reactive group content. A Certificate of Analysis (COA) detailing purity, physical properties, and application performance is provided with every shipment 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 a controlled 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.
