Indigo Blue Vat Blue - Anping County Wu Xin Chemical Dye Co., Ltd.

Indigo Blue Vat Blue, also known as Indigo Dye, is a time-honored synthetic dye that has remained a cornerstone of the textile industry. Its unique chemical properties and vibrant color make it indispensable for producing denim fabrics, particularly for blue jeans. This article delves into the technical specifications, applications, and the company behind this product, Anping County Wu Xin Chemical Dye Co., Ltd., while ensuring alignment with authoritative standards such as those outlined by the National Institute of Standards and Technology (NIST).

Product Overview: Indigo Blue Vat Blue

Indigo Blue Vat Blue is a dark blue crystalline powder with a molecular formula of C₁₆H₁₀N₂O₂ and a CAS number of 482-89-3. It is insoluble in water, alcohol, and ether but dissolves in organic solvents like DMSO, chloroform, and concentrated sulfuric acid. The dye sublimes at temperatures ranging from 390–392°C (734–738°F), a property that underscores its thermal stability. This chemical structure and behavior make it ideal for industrial applications, particularly in the textile sector.

As a light indigo color product, it is widely recognized for its deep, even grains and high purity. The product is available in multiple packaging options, including 20kg cartons, 25kg bags, and 500–550kg bags, catering to diverse logistical needs. Its validity is two years when stored under optimal conditions, ensuring long-term usability for manufacturers and suppliers.

The product’s versatility is further enhanced by its compatibility with light indigo color suppliers and light indigo color manufacturers, making it a preferred choice for global textile producers. Its role in the production of denim and blue jeans is particularly notable, with an average usage of 3–12 grams per pair of jeans.

Technical Specifications and Quality Standards

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

The product adheres to strict quality standards, ensuring consistency and reliability. According to the National Institute of Standards and Technology (NIST), chemical substances like indigo must meet rigorous criteria for purity and stability to maintain their industrial utility. The specifications provided align with these benchmarks, as noted in NIST’s guidelines on synthetic dyes and textile chemicals. For instance, the NIST Chemistry WebBook offers detailed data on the molecular properties of indigo, reinforcing its role as a standard in the industry.

Applications and Industry Use Cases

Indigo Blue Vat Blue is primarily used for dyeing cotton yarn, making it a critical component in the production of denim fabric. Its ability to withstand processes like stone washing and acid washing makes it ideal for creating the distinctive faded and worn looks popular in modern denim styles. Smaller quantities are also used for dyeing wool and silk, showcasing its versatility across textile types.

The dye’s solubility in organic solvents allows for efficient application in industrial settings, where precision and scalability are paramount. Its thermal stability ensures that it retains its color and integrity during high-temperature processes, a critical factor in textile manufacturing. Additionally, its low water content (≤1%) and minimal iron ion impurities (≤200ppm) reduce the risk of discoloration or degradation, further enhancing its appeal.

Storage, Transportation, and Safety

Proper storage and transportation are essential to maintaining the product’s quality. The light indigo color factories recommend storing the dye in a cool, ventilated, and dry warehouse with a temperature below 25°C and humidity below 75%. The packaging must remain sealed to prevent moisture exposure, which can lead to oxidation and deterioration. It should also be kept away from acids, alkalis, strong oxidants, and reducing agents to avoid chemical interactions that could compromise its stability.

During transportation, the product must be protected from sunlight, rain, and high temperatures. It should not be mixed with oxidants or edible chemicals, as per light indigo color pricelist guidelines. These precautions ensure that the dye reaches its destination in optimal condition, ready for use in textile production.
