Description

Procion Brilliant Yellow H3G is a highly reactive, water-soluble fiber-reactive dye belonging to the monochlorotriazine class. It is engineered to deliver brilliant, wash-fast yellow coloration to cellulosic materials through covalent bonding. This dye is essential for manufacturers in the textile industry seeking consistent, high-quality, and economical dyeing solutions for cotton, viscose, and other natural fibers.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, linen, hemp, and regenerated cellulose fibers like viscose and lyocell.
• Textile Printing: Used in printing pastes for creating vibrant, durable yellow patterns and designs on cellulosic fabrics.
• Garment Dyeing: Suitable for batch dyeing of finished cotton garments, offering excellent levelness and penetration.
• Yarn Dyeing: Applied for dyeing cotton and blended yarns in hank, package, or beam dyeing machines.
• Technical Textiles: Coloration of cellulosic components in non-apparel textiles, including home furnishings and industrial fabrics.
• Research & Development: Serves as a key intermediate or reference standard in dye chemistry research and quality control laboratories.

Quality Control

Every batch of Procion Brilliant Yellow H3G is manufactured under a stringent quality management system. We ensure compliance with industry standards for reactive dyes, including parameters for color strength, shade, solubility, and fixation rate. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance characteristics is provided with each shipment to guarantee batch-to-batch consistency.

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 and incompatible materials. The product is hygroscopic (moisture-sensitive); ensure the original packaging is resealed tightly after use to prevent moisture absorption and caking.
