Indigo Blue Vat Blue, also known as Indigo Blue, is a versatile and historically significant dye that has played a pivotal role in textile manufacturing for centuries. This dark blue crystalline powder is renowned for its unique chemical properties and wide-ranging applications, particularly in the production of denim fabric for blue jeans. This article delves into the product's specifications, usage scenarios, and the company behind its production, while also referencing authoritative standards from the National Institute of Standards and Technology (NIST) to ensure credibility.
The Indigo Blue Vat Blue is manufactured to meet rigorous quality standards, as outlined in the following specifications:
| Parameter | Specification |
|---|---|
| Appearance | Dark blue even grains |
| Purity | ≥94% |
| Water Content | ≤1% |
| Iron Ion Content | ≤200ppm |
These specifications ensure that the product maintains its chemical stability and dyeing efficiency. According to NIST's guidelines on chemical standards (NIST), such precise measurements are critical for industrial applications, ensuring consistency and safety in production processes.
Indigo Blue Vat Blue is a dark blue crystalline powder with a sublimation point of 390–392°C (734–738°F). It is insoluble in water, alcohol, and ether but dissolves in solvents like DMSO, chloroform, and concentrated sulfuric acid. Its chemical formula is C16H10N2O2, as noted in the product's technical data sheet (Product Details).
The primary application of this dye is in the textile industry, particularly for cotton yarn used in denim fabric. A single pair of blue jeans typically requires 3–12 grams of indigo dye. Smaller quantities are also used for wool and silk. Its unique properties enable processes like stone washing and acid washing, which are essential for achieving the distinctive look of denim garments.
The product is available in multiple packaging options to suit different shipping needs:
Transportation guidelines emphasize strict safety measures. The dye must not be mixed with oxidants or edible chemicals. It should be protected from sunlight, rain, and high temperatures during transit. When stopping, it must be kept away from fire, heat sources, and high-temperature areas (Product Specifications).
Proper storage is crucial to maintaining the quality of Indigo Blue Vat Blue:
The product has a shelf life of two years under optimal conditions (Product Details).
