Vat Black Textile Dye Cellulosic Fiber

Description

1. Product Overview

Vat Black Textile Dye for Cellulosic Fiber is a high-performance industrial dye designed specifically for deep, uniform, and long-lasting black coloration of cotton and other cellulosic substrates. It is widely used in large-scale textile processing where superior color fastness, shade depth, and reproducibility are critical. The product delivers excellent reduction and re-oxidation performance, ensuring strong fiber penetration and stable dye fixation. Strategically, it remains a cornerstone dye class for manufacturers seeking premium dark shades with minimal shade variation across production batches.

2. Key Specifications & Technical Characteristics

• Chemical class: Vat dye (anthraquinone-based derivatives typical of vat black systems)
• Active content: ≥ 85–95% (industrial grade, depending on formulation)
• Physical form: Fine powder
• Color index: Deep black / jet black shade system
• Particle size: Micronized for uniform dispersion in dye baths
• Solubility: Insoluble in water; requires alkaline reduction system (vatting process)
• pH (1% dispersion): Alkaline compatibility range
• Packaging options: 25 kg HDPE drums or laminated export-grade bags
• Shelf life: 24–36 months under dry, cool storage conditions

3. Core Industrial Applications
