Indigo Blue Vat Blue - Wuxin Group | Textile Dye, Denim Application

Introduction

Indigo Blue Vat Blue, also known as Indigo Dye, is a time-honored textile dye celebrated for its vibrant color and durability. This article provides an in-depth exploration of its properties, applications, and the company behind its production. Whether you're a textile manufacturer or a chemical supplier, understanding the intricacies of this dye is essential for quality assurance and optimal usage.

Product Overview

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 primarily used for dyeing cotton fabrics, particularly in the production of denim for blue jeans. The dye's unique solubility profile and chemical stability make it a preferred choice in the textile industry. For more details, visit the product page.

Technical Specifications

The dye's high purity ensures consistent coloration, while its low water content minimizes the risk of degradation during storage and transportation. For detailed specifications, refer to the product page.

Key Characteristics

Indigo Blue Vat Blue is insoluble in water, alcohol, and ether but dissolves in solvents like DMSO, chloroform, and concentrated sulfuric acid. It sublimes at 390–392°C (734–738°F). These properties make it ideal for vat dyeing processes, where it binds effectively to cellulose fibers. According to the National Institute of Standards and Technology (NIST), such chemical stability is critical for industrial applications requiring long-term durability.

Applications and Usage

The primary application of Indigo Blue Vat Blue is in the textile industry, particularly for dyeing cotton yarn used in denim production. A single pair of blue jeans typically requires 3–12 grams of dye. It is also used for wool and silk, though in smaller quantities. The dye's compatibility with stone washing and acid washing processes allows for unique fabric textures and finishes.

Packaging and Logistics

Indigo Blue Vat Blue is packaged in 20kg cartons, 25kg bags, or 500–550kg bags, depending on customer requirements. Shipping details include:

• 20kg cartons: 9mt (no pallet) in 20'GP container111; 18tons (with pallet) in 40'HQ container111
• 25kg bags: 12mt in 20'GP; 25mt in 40'HQ
• 500–550kg bags: 20–22mt in 40'HQ

Proper packaging ensures minimal contamination and facilitates efficient transportation. Contact the company for customized packaging solutions.

Storage and Handling

To maintain quality, store Indigo Blue Vat Blue 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 ingress. Avoid exposure to sunlight, air, acids, alkalis, and strong oxidants. For safety guidelines, consult the product documentation.

Transportation Guidelines

The dye must be transported separately from oxidants and edible chemicals. Protect it from sunlight, rain, and high temperatures. During stops, keep it away from fire sources and heat. Adhering to these protocols ensures safe delivery and maintains product integrity.
