Disperse Orange S-4RL | C.I. Disperse Orange 30 - High-Quality Dye from China Suppliers & Factory
Product Overview
C.I. Disperse Orange 30, commercially named Disperse Orange S-4RL, is a high-temperature azo disperse dye with balanced and stable performance. As a classic primary orange component for polyester dyeing and printing, it features high tinting strength, pure and full shade, and comprehensive excellent color fastness. It is an essential supporting dye for high-temperature three-primary color disperse dyes, with strong versatility and color compatibility for various synthetic fiber processing.
Core Physical, Chemical and Dyeing Properties
This dye is insoluble in water and soluble in organic solvents such as acetone, DMF and aromatic solvents. The optimal pH range of the dye bath is 4-7, achieving the best dyeing effect in neutral and weak acid conditions. It owns excellent dispersibility and outstanding high-temperature stability, with no agglomeration, screen clogging or crystallization during high-temperature processing, and presents superior levelness and permeability. Copper and iron ions shall be avoided in the dyeing process to prevent shade dullness and deviation. It shows a pure bright orange shade without variegation, maintaining uniform and full color in light, medium and deep dyeing.
Frequently Asked Questions
