Introduction

Indigo blue vat blue, a dark blue crystalline powder, has been a cornerstone in the textile industry for centuries. Known for its vibrant color and durability, this dye is particularly renowned for its use in light indigo color products such as denim fabric and blue jeans. This article delves into the technical specifications, applications, and industry standards of indigo blue vat blue, while also highlighting the role of light indigo color manufacturers like Anping County Wuxin Chemical Dye Co., Ltd. in ensuring its quality and availability.

Product Overview

Indigo blue vat blue is a natural dye derived from the Indigofera plant, though modern production often involves synthetic processes. Its chemical formula is C₁₆H₁₀N₂O₂, and it is characterized by its insolubility in water, alcohol, and ether, yet solubility in organic solvents like DMSO and chloroform. The dye sublimes at temperatures between 390–392°C (734–738°F), making it suitable for high-temperature industrial processes.
