Indigo Blue Vat Blue-Anping County Wu Xin Chemical Dye Co., Ltd.|Denim Dyeing, Textile Industry

Indigo Blue Vat Blue, a dark blue crystalline powder with the chemical formula C16H10N2O2, stands as a cornerstone in the textile industry. Known for its exceptional dyeing properties and versatility, this product has been a preferred choice for denim production and other textile applications for decades. This article delves into the technical specifications, applications, and industry standards of Indigo Blue Vat Blue, while also highlighting the expertise of its manufacturer, Anping County Wu Xin Chemical Dye Co., Ltd..

Product Overview

Indigo Blue Vat Blue is a natural dye derived from the Indigofera plant, but modern production methods often involve synthetic processes to ensure consistency and purity. The product is characterized by its dark blue even grains and is widely recognized for its ability to produce vibrant, long-lasting colors. Its chemical properties make it an ideal choice for dyeing cotton, wool, and silk, with a particular emphasis on denim production.

Technical Specifications

The Indigo Blue Vat Blue meets rigorous quality standards, as outlined in the following table:

Parameter	Specification
Appearance	Dark blue even grains
Purity	≥94%
Water Content	≤1%
Iron Ion Content	≤200ppm

With a molecular weight of 262.62 and a CAS number of 482-89-3, this dye is known for its stability and solubility in specific solvents such as DMSO, chloroform, and concentrated sulfuric acid. However, it is insoluble in water, which necessitates the use of specialized techniques for application.

Applications in Textile Industry

The primary use of Indigo Blue Vat Blue lies in the dyeing of cotton yarn, particularly for the production of denim cloth used in blue jeans. On average, a pair of blue jeans requires between 3 grams (0.11 oz) to 12 grams (0.42 oz) of dye. This makes it a cost-effective and efficient solution for textile manufacturers.

Smaller quantities are also used for dyeing wool and silk, where its unique properties allow for advanced finishing techniques such as stone washing and acid washing. These processes enhance the texture and appearance of the fabric, creating the distinctive look associated with denim.

Packaging and Logistics

Indigo Blue Vat Blue is available in various packaging options to suit different shipping and storage needs:

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

Proper transportation is critical to maintaining the quality of the product. It must be transported separately from oxidants and edible chemicals, and protected from sunlight, rain, and high temperatures. During transit, it should be stored away from fire, heat sources, and high-temperature areas.

Storage and Handling

To preserve the integrity of Indigo Blue Vat Blue, the following storage guidelines must be followed:

1. Store in a cool, ventilated, and dry warehouse, with a temperature below 25°C and relative humidity below 75%.
2. Ensure complete sealing of the packaging to prevent moisture-induced deterioration. Avoid prolonged exposure to sunlight or air, which can cause oxidation and degradation.
3. Store isolated from acids, alkalis, strong oxidants (e.g., potassium nitrate, ammonium nitrate), and reducing agents to prevent adverse reactions.

The product has a two-year shelf life under proper storage conditions, ensuring long-term usability for manufacturers and suppliers.
