Description

Reactive Red 167 is a high-performance, water-soluble azo dye belonging to the reactive dye class, designed for covalent bonding with textile fibers. This compound is valued for its excellent color fastness, brilliant red hue, and efficient fixation properties, ensuring durable and vibrant coloration. It is primarily used by manufacturers in the textile industry for dyeing and printing cellulosic fibers like cotton, viscose, and linen, as well as in applications requiring a stable and intense red shade.

Application

• Primary application in the exhaust dyeing of cotton and other cellulosic fabrics.
• Used in continuous dyeing processes, including pad-batch and pad-steam methods.
• Employed in the printing of textiles to create sharp and durable patterns.
• Suitable for dyeing blended fabrics containing cellulosic components.
• Potential use in the coloration of leather and paper, depending on formulation.
• Applied in research and development for creating new color formulations and shades.

Quality Control

Our Reactive Red 167 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested for critical parameters including color strength, solubility, fixation rate, and impurity profile to meet industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee product integrity and 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
