Indigo Blue Vat Blue-Anping County Wuxin Chemical Dye Co., Ltd.|High-Purity Dye&Textile Applications

Introduction

Indigo Blue Vat Blue, also known as Indigo Blue, is a high-purity dye that has been a cornerstone in the textile industry for centuries. Its deep blue hue and exceptional durability make it a preferred choice for denim production and other textile applications. This article provides an in-depth analysis of the product's features, advantages, technical specifications, and applications, along with insights into its manufacturing and storage requirements.

Product Features and Advantages

Indigo Blue Vat Blue is a dark blue crystalline powder that sublimes at temperatures between 390–392°C (734–738°F). It is insoluble in water, alcohol, and ether but soluble in organic solvents like DMSO, chloroform, nitrobenzene, and concentrated sulfuric acid. The chemical formula of indigo is C₁₆H₁₀N₂O₂, which contributes to its unique properties.

One of the key advantages of Indigo Blue Vat Blue is its ability to produce vibrant, long-lasting colors on natural fibers such as cotton, wool, and silk. Its resistance to fading under sunlight and washing makes it ideal for denim manufacturing, where it is used to create the iconic blue jeans. According to the National Institute of Standards and Technology (NIST), indigo's molecular stability ensures consistent colorfastness, which is critical for industrial textile applications.

Applications in Textile Industry

Indigo Blue Vat Blue is primarily used for dyeing cotton yarn, which is essential in the production of denim fabric. On average, a single pair of blue jeans requires 3–12 grams of dye, depending on the desired shade and wash effect. Its versatility extends to wool and silk dyeing, where it provides a rich, deep blue color. The dye's compatibility with processes like stone washing and acid washing allows for the creation of unique textures and finishes in denim garments.

According to NIST, the dye's solubility in specific solvents and its chemical stability make it suitable for both traditional and modern textile processing techniques. This ensures that manufacturers can achieve consistent quality while meeting environmental and safety standards.

Packaging and Transportation

Indigo Blue Vat Blue is available in multiple packaging options to suit different shipping needs:

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

During transportation, it is critical to avoid mixing with oxidants or edible chemicals. The product must be protected from sunlight, rain, and high temperatures. When stopping over, it should be kept away from fire, heat sources, and high-temperature areas. Proper handling ensures the dye's integrity and prevents contamination.

Storage Guidelines

1. Store in a cool, ventilated, and dry warehouse. Keep sealed during the rainy season. Maintain a temperature below 25°C and relative humidity below 75%.
2. Ensure packaging is completely sealed to prevent moisture-induced deterioration. Avoid prolonged exposure to sunlight or air, which can cause oxidation and degradation.
3. Store separately from acids, alkalis, strong oxidants (e.g., potassium nitrate, ammonium nitrate), and reducing agents to prevent reactions that could lead to deterioration or combustion.
