Description

C.I. Reactive Black 14 is a high-performance, bifunctional reactive dye belonging to the azo chemical class, designed to form covalent bonds with cellulosic fibers. This compound is essential for achieving deep, durable black shades with excellent wash and light fastness properties in textile dyeing and printing processes. It is a critical raw material for textile manufacturers, ink formulators, and industrial colorant producers seeking reliable and consistent coloration.

Application

• Textile Dyeing: Primary application for dyeing cotton, viscose, linen, and other cellulosic fibers to produce deep black shades.
• Textile Printing: Used in pigment printing pastes and inks for creating sharp, black patterns on fabrics.
• Leather Coloring: Employed in the dyeing of leather goods to provide rich, uniform black coloration.
• Ink Manufacturing: A key component in the formulation of specialty inks for various industrial marking and printing applications.
• Paper Staining: Used for tinting and coloring specialty papers where high color strength is required.
• Research & Development: Serves as a standard or intermediate in chemical research for developing new dyes and colorants.
