Description

Reactive Red 177 is a high-performance, water-soluble reactive dye belonging to the azo dye class, widely recognized for its vibrant red color and excellent fastness properties. Its primary value lies in its ability to form a covalent bond with cellulosic fibers, resulting in brilliant, wash-fast, and lightfast coloration. This dye is essential for manufacturers in the textile industry seeking reliable and efficient coloring solutions for cotton, viscose, and other natural fabrics. The compound is supplied as a powder and is identified by CAS No. 68110-24-7.

Application

Reactive Red 177 is specifically engineered for dyeing and printing applications where color fastness is critical. Its primary and related uses include:

• Exhaust Dyeing of Cellulosic Fibers: Used in batch dyeing processes for cotton, rayon, linen, and hemp to achieve deep, even shades.
• Continuous Dyeing: Applied in pad-batch and pad-steam processes for efficient, large-scale fabric production.
• Textile Printing: Formulated for use in printing pastes to create sharp, durable patterns on fabrics.
• Garment Dyeing: Suitable for dyeing finished knitwear and other garments.
• Technical Textiles: Used for coloring textiles where performance and color consistency are paramount.

Quality Control

Our Reactive Red 177 is manufactured under a strict quality management system. Every batch is tested to ensure consistent shade, strength, and application performance. Key parameters such as color strength, solubility, and fixation rate are rigorously controlled. A Certificate of Analysis (COA) detailing purity, physical properties, and application test results is provided with each shipment to guarantee it meets your specific technical requirements.

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 prolonged exposure to high humidity should be avoided to maintain stability and performance.
