Description

Reactive Blue 195 is a high-performance, vinyl sulfone-based reactive dye belonging to the anthraquinone chemical class. It is valued for its excellent color yield, good wash and light fastness properties, and high fixation rate on cellulosic fibers. This dye is essential for manufacturers in the textile industry seeking brilliant and durable blue shades. Reactive Blue 195 CAS NO 135990-86-2 is a key component for dyeing and printing cotton, viscose, and other natural fibers.

Application

Reactive Blue 195 is primarily used in the textile wet processing industry. Its specific applications include:

• Exhaust Dyeing of Cotton: For producing medium to dark blue shades with high reproducibility in jet, overflow, and beam dyeing machines.
• Continuous Dyeing: Applied in pad-batch, pad-steam, and pad-dry-chemical pad-steam processes for efficient, large-scale fabric coloration.
• Textile Printing: Used in pigment printing and discharge printing processes on cellulosic fabrics to create sharp, defined patterns.
• Viscose and Linen Dyeing: Effective for dyeing regenerated cellulose (viscose/rayon) and linen, providing good penetration and levelness.
• Yarn Dyeing: Suitable for package and hank dyeing of cotton and blended yarns intended for weaving or knitting.
• Dyeing of Cellulosic Blends: Can be used in combination with appropriate dyes for polyester/cotton or nylon/cotton blend fabrics.

Quality Control

Our Reactive Blue 195 is manufactured under a stringent quality management system. Every batch is tested against rigorous internal specifications to ensure consistent shade, strength, solubility, and fixation properties. Key parameters such as color strength, hue, and impurity profile are controlled. A Certificate of Analysis (COA) detailing purity, physical properties, and performance characteristics is provided with each shipment to guarantee it meets the demands of industrial textile processing.

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 heat, sparks, and open flame. The product is light-sensitive (store away from light) and should be kept in its original packaging until use to prevent moisture absorption and contamination.
