Description

C.I. Reactive Blue 23 is a high-purity, anthraquinone-based reactive dye renowned for its brilliant blue hue and excellent fastness properties. Its primary value lies in its ability to form covalent bonds with cellulosic fibers, ensuring exceptional wash and light fastness in the final textile product. This dye is essential for manufacturers in the textile industry, particularly for dyeing and printing cotton, viscose, and other natural fibers. It is also utilized in specialized applications requiring a stable and vibrant blue colorant.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, linen, rayon, and other cellulosic fabrics.
• Textile Printing: Used in pigment printing processes for creating sharp, durable blue designs on garments and home textiles.
• Leather Coloring: Employed in the dyeing of leather goods to achieve consistent and fast blue colors.
• Paper Coloring: Suitable for tinting specialty papers where color fastness is a requirement.
• Research & Development: Serves as a reference standard or intermediate in chemical synthesis and dye research laboratories.
• Industrial Colorant: Potential use in coloring non-textile materials where a reactive blue dye is specified.

Quality Control

Our C.I. Reactive Blue 23 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Every lot is tested against rigorous internal specifications for critical parameters such as color strength, shade, solubility, and reactive group content. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance metrics is provided with each shipment to guarantee it meets the demands of industrial dyeing processes.

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 resealed tightly after use to prevent moisture absorption and caking.
