Description

Reactive Red 195 is a high-performance, bifunctional reactive dye belonging to the azo dye class, specifically engineered for covalent bonding with cellulosic fibers. Its primary value lies in delivering exceptional color fastness, brilliant shade, and high fixation efficiency, which are critical for cost-effective and sustainable textile dyeing operations. This product is essential for manufacturers in the textile industry seeking reliable and vibrant red hues on cotton, viscose, and other cellulose-based materials.

Application

• Exhaust Dyeing of Cotton: Primary application for dyeing cotton yarns and fabrics in batch processes, offering excellent levelness and reproducibility.
• Continuous Dyeing (Pad-Batch/Steam): Suitable for high-throughput continuous dyeing ranges for woven and knitted cellulosic textiles.
• Viscose and Lyocell Dyeing: Effective for dyeing regenerated cellulose fibers like viscose and Tencel®, providing deep and even shades.
• Textile Printing: Used in the formulation of printing pastes for direct and discharge printing on cellulose fabrics.
• Blend Dyeing (Cotton/Polyester): Can be applied in one-bath or two-bath processes for dyeing cotton components in polyester/cotton blends.
• Garment Dyeing: Ideal for the piece-dyeing of finished garments, offering flexibility for fashion and apparel production.

Quality Control

Our Reactive Red 195 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including color strength, shade, solubility, and fixation rate. A Certificate of Analysis (COA) detailing purity, physical properties, and application performance is provided with each 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 room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure the original packaging is sealed after use to prevent moisture absorption and caking.
