Indigo Blue Vat Blue, a premium dye known for its vibrant color and durability, has been a cornerstone in the textile industry for decades. Produced by Wuxin Chemical, this product is engineered to meet the highest standards of quality and performance. Whether used in denim production or other textile applications, Indigo Blue Vat Blue offers unmatched versatility and reliability. This article explores its features, advantages, technical specifications, and the company behind its excellence.
Indigo Blue Vat Blue is a dark blue crystalline powder with a chemical formula of C16H10N2O2. Its unique properties make it ideal for dyeing cotton, wool, and silk. Below is a detailed overview of its technical specifications:
| Parameter | Specification |
|---|---|
| Appearance | Dark blue even grains |
| Purity | ≥94% |
| Water Content | ≤1% |
| Iron Ion Content | ≤200ppm |
The product's high purity ensures consistent color outcomes, while its low water content and minimal iron ion levels reduce the risk of impurities during the dyeing process. These specifications align with industry standards, making Indigo Blue Vat Blue a trusted choice for manufacturers worldwide.
One of the standout features of Indigo Blue Vat Blue is its exceptional colorfastness. This dye is renowned for its ability to retain its vibrancy even after repeated washing and exposure to sunlight. Additionally, its solubility in organic solvents like DMSO and chloroform allows for efficient application in various textile processes.
Another significant advantage is its role in denim production. A single pair of blue jeans typically requires 3–12 grams of this dye, making it a cost-effective solution for large-scale manufacturing. The dye also supports advanced techniques such as stone washing and acid washing, enabling the creation of unique textures and finishes in denim fabrics.

Moreover, Indigo Blue Vat Blue is designed for ease of handling. Its packaging options—ranging from 20kg cartons to 500–550kg bags—ensure flexibility for different shipping and storage needs. The product’s two-year shelf life further enhances its value for businesses seeking long-term reliability.
The primary application of Indigo Blue Vat Blue is in the dyeing of cotton yarn, particularly for denim. This dye is integral to the production of blue jeans, where its properties allow for the creation of the iconic blue hue. The dye’s ability to withstand harsh treatments like stone washing and acid washing makes it a favorite among denim manufacturers.
Beyond denim, Indigo Blue Vat Blue is also used in the dyeing of wool and silk, offering a rich, deep color that is both aesthetically pleasing and durable. Its versatility extends to other textile applications, including the production of industrial fabrics and apparel where color consistency and longevity are critical.

For manufacturers, the dye’s solubility in organic solvents simplifies the application process, reducing the need for complex chemical formulations. This efficiency not only saves time but also minimizes waste, aligning with modern sustainability goals in the textile industry.
