Indigo Blue Vat Blue-Anping County Wuxin Chemical Dye Co., Ltd.|Durable Textile Dye&High Purity Standards

Indigo Blue Vat Blue, a staple in the textile industry, has been a cornerstone of dyeing processes for centuries. This article provides an in-depth analysis of its technical specifications, usage scenarios, and the company behind its production. With a focus on indigo blue as a critical component in denim manufacturing, we explore its chemical properties, packaging logistics, and storage requirements. The article also highlights the importance of industry standards, referencing National Institute of Standards and Technology (NIST) to emphasize the role of measurement science in ensuring product quality.

Product Overview and Quality Standards

Indigo Blue Vat Blue is a dark blue crystalline powder known for its unique solubility properties and durability. Its chemical formula is C₁₆H₁₀N₂O₂, and it sublimes at temperatures ranging from 390–392°C (734–738°F). This compound is insoluble in water, alcohol, and ether but dissolves in solvents like DMSO, chloroform, and concentrated sulfuric acid. The product's quality is defined by strict specifications, ensuring consistency for industrial applications.

Key Quality Specifications

Parameter	Specification
Appearance	Dark blue even grains
Purity	≥94%
Water Content	≤1%
Iron Ion Content	≤200ppm

Chemical Characteristics and Industrial Applications

The indigo dye is primarily used for dyeing cotton yarn, making it indispensable in the production of denim fabric for blue jeans. On average, a single pair of jeans requires 3–12 grams of dye, highlighting its efficiency in textile manufacturing. Beyond cotton, smaller quantities are used for wool and silk, where its resistance to fading and ability to withstand mechanical treatments like stone washing and acid washing make it a preferred choice.

Packaging and Logistics

Indigo Blue Vat Blue is available in multiple packaging options to suit different shipping needs:

• 20kg cartons (or by customer’s requirement): 9mt (no pallet) in 20'GP container111; 18tons (with pallet) in 40'HQ container111
• 25kgs bag (or by customer’s requirement): 12mt in 20'GP container111; 25mt in 40'HQ container111
• 500–550kgs bag (or by customer’s requirement): 20–22mt in 40'HQ container111

Proper transportation is critical to maintaining product integrity. The dye must be transported separately from oxidants and edible chemicals. Exposure to sunlight, rain, and high temperatures should be avoided, and storage should occur in cool, ventilated, and dry conditions. For detailed shipping guidelines, refer to the product documentation.

Storage and Shelf Life

Storage conditions are crucial for preserving the quality of Indigo Blue Vat Blue. The product must be kept in a sealed environment, with temperatures controlled below 25°C and humidity below 75%. It should be stored away from acids, alkalis, strong oxidants, and reducing agents to prevent degradation. The shelf life is two years under optimal conditions.

Industry Relevance and Standards

The importance of precise measurements in chemical production is underscored by the work of NIST, the National Institute of Standards and Technology. As the U.S. National Metrology Institute, NIST establishes standards for scientific measurements, ensuring consistency across industries. While the NIST does not directly regulate indigo blue production, its role in defining measurement protocols is critical for quality control in chemical manufacturing.

According to NIST, "Accurate measurement is the foundation of innovation, enabling industries to develop reliable products and processes" (NIST, 2025). This principle applies to the production of dyes like Indigo Blue Vat Blue, where even minor deviations in purity or solubility can impact end-use performance.

Conclusion

Indigo Blue Vat Blue remains a vital component in the textile industry, offering durability, colorfastness, and versatility. Its technical specifications, combined with the company's commitment to quality, make it a reliable choice for manufacturers. As the industry evolves, adherence to measurement standards—such as those promoted by NIST—ensures that products like indigo blue continue to meet global demands.
