Indigo Blue Vat Blue-Indigo Blue|Premium Dye,High-Purity Chemical

Indigo Blue Vat Blue, also known as light indigo color product, is a cornerstone in the textile industry, renowned for its deep blue hue and exceptional dyeing properties. This article delves into the technical specifications, applications, and industry relevance of this versatile dye, while highlighting the expertise of light indigo color company, Anping County Wu Xin Chemical Dye Co., Ltd.

Product Overview

Indigo Blue Vat Blue is a dark blue crystalline powder with a chemical formula of C₁₆H₁₀N₂O₂. It is insoluble in water, alcohol, and ether but soluble in solvents like DMSO and chloroform. This unique solubility profile makes it ideal for textile dyeing, particularly for cotton fabrics used in denim production. The dye is also recognized for its sublimation point of 390–392°C (734–738°F), ensuring stability during industrial processes.

The dye’s properties enable advanced finishing techniques like stone washing and acid washing, which create the signature worn look of denim. These processes rely on the dye’s ability to withstand chemical treatments without losing color integrity.

Packaging and Logistics

Indigo Blue Vat Blue is packaged in 20kg cartons, 25kg bags, and 500–550kg bulk bags, with specifications tailored to customer requirements. The product’s logistics are optimized for efficiency:

• 20kg cartons: 9 metric tons (no pallet) in a 20’GP container111; 18 tons (with pallet) in a 40’HQ container111.
• 25kg bags: 12 metric tons in a 20’GP container111; 25 metric tons in a 40’HQ container111.
• 500–550kg bags: 20–22 metric tons in a 40’HQ container111.

Storage and Transportation

To maintain quality, the product must be stored in a cool, ventilated, and dry warehouse with temperatures below 25°C and humidity under 75%. Packaging should remain sealed to prevent moisture exposure, which can cause oxidation and degradation. During transportation, it must be protected from sunlight, rain, and high temperatures, and kept away from oxidants, acids, and heat sources.
