Indigo Blue Vat Blue- Wuxin Chemical|High Purity&Thermal Stability

Introduction to Indigo Blue Vat Blue

Indigo Blue Vat Blue, also known as Indigo Blue, is a high-purity dye widely used in the textile industry. This dark blue crystalline powder is renowned for its exceptional colorfastness and versatility in applications ranging from denim production to specialty fabric treatments. Developed by Anping County Wuxin Chemical Dye Co., Ltd., the product adheres to stringent quality standards, making it a preferred choice for manufacturers globally.

Product Features

Indigo Blue Vat Blue is characterized by its unique chemical properties and durability. Key features include:

• High Purity: With a minimum purity of 94%, it ensures vibrant and long-lasting coloration.
• Low Moisture Content: ≤1% moisture content prevents clumping and maintains stability during storage.
• Minimal Iron Ion Contamination: ≤200ppm iron ions reduce the risk of discoloration in finished textiles.
• Thermal Stability: Sublimates at 390–392°C, making it suitable for high-temperature dyeing processes.

Its insolubility in water and common solvents like alcohol or ether, combined with solubility in DMSO and chloroform, allows for precise application in industrial settings. The chemical formula, C₁₆H₁₀N₂O₂, underscores its complex molecular structure, which contributes to its deep blue hue and resistance to fading.

Technical Specifications

Application Scenarios

Indigo Blue Vat Blue is primarily used in the textile industry, particularly for dyeing cotton yarn and producing denim fabric. A single pair of blue jeans typically requires 3–12 grams of the dye, highlighting its efficiency in large-scale manufacturing. Beyond denim, it is also employed for dyeing wool and silk, though in smaller quantities.

The dye's compatibility with stone washing and acid washing processes makes it ideal for creating distressed or vintage finishes on denim. Its ability to withstand repeated washing and exposure to sunlight ensures that the color remains consistent, meeting the demands of modern fashion trends.
