Description

Reactive Violet 34 is a high-purity, reactive dye belonging to the vinyl sulfone class, known for its excellent color yield and wash-fastness properties. Its primary value lies in its ability to form a strong covalent bond with cellulose fibers, ensuring vibrant and durable coloration. This product is essential for manufacturers in the textile industry seeking reliable and consistent dyes for cotton, viscose, and other cellulosic materials.

Application

• Primary dyeing of cotton fabrics and yarns for apparel and home textiles.
• Coloration of viscose (rayon) and other regenerated cellulose fibers.
• Used in exhaust dyeing processes for batch production of cellulosic textiles.
• Application in continuous dyeing and pad-batch processes for efficient, large-scale operations.
• Suitable for dyeing blended fabrics where the cellulosic component requires coloration.
• Employed in the production of fast-colored textiles requiring high resistance to washing and light.

Quality Control

Our Reactive Violet 34 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including color strength, solubility, and fixation properties to meet the demanding requirements of industrial textile dyeing. A comprehensive Certificate of Analysis (COA) detailing purity, shade, and physical properties is provided with every shipment.

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); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
