Description

Reactive Orange 95 is a high-performance, bifunctional reactive dye belonging to the azo chemical class, designed for covalent bonding with cellulosic fibers. Its primary value lies in delivering brilliant orange shades with excellent wet fastness properties, including wash, light, and perspiration fastness, ensuring color durability in demanding applications. This dye is essential for textile manufacturers and dye houses specializing in the coloration of cotton, viscose, linen, and their blends, particularly where vibrant, long-lasting orange hues are required. The compound is identified by the CAS registry number 107028-82-0.

Application

Reactive Orange 95 is engineered for textile dyeing and printing processes where color fixation and fastness are critical. Its primary applications include:

• Exhaust Dyeing of Cellulosics: For dyeing cotton, rayon, and linen in jet, beck, and jig machines.
• Continuous Dyeing: Used in pad-batch and pad-steam processes for uniform coloration.
• Textile Printing: Formulated for printing pastes to create sharp, defined orange patterns on fabrics.
• Garment Dyeing: Suitable for dyeing finished knitted and woven garments.
• Union Dyeing: Effective for dyeing blends of cotton with polyester or nylon.
• Technical Textiles: Used for coloring textiles where high lightfastness is required, such as awnings and outdoor fabrics.
