Introduction

Indigo Blue Vat Blue, also known as Indigo Dye, is a renowned organic compound with a long history in textile industries. This dark blue crystalline powder is primarily used for dyeing cotton fabrics, particularly in the production of denim for blue jeans. Its unique chemical properties and versatility make it a critical component in modern textile manufacturing. This article provides an in-depth analysis of its technical specifications, applications, and the company behind its production.

Product Overview

Indigo Blue Vat Blue is a synthetic organic dye with the chemical formula C₁₆H₁₀N₂O₂. It is a dark blue crystalline powder that sublimes at temperatures ranging from 390–392°C (734–738°F). Its insolubility in water, alcohol, and ether, combined with solubility in solvents like DMSO and chloroform, makes it ideal for specific industrial applications. The dye is commonly associated with the production of denim and blue jeans, where it enables techniques such as stone washing and acid washing.

Key Features

• High Purity: ≥94%
• Low Water Content: ≤1%
• Iron Ion Content: ≤200ppm
• Chemical Stability: Resists degradation under standard conditions

Technical Specifications

Applications and Usage

Indigo Blue Vat Blue is predominantly used in the textile industry for dyeing cotton yarn, especially in the production of denim. A single pair of blue jeans typically requires 3–12 grams of the dye. While its primary application is in cotton, smaller quantities are also used for dyeing wool and silk. The dye's ability to withstand mechanical and chemical treatments makes it suitable for advanced finishing techniques like stone washing and acid washing, which create the distinctive faded look of denim.

Packaging and Logistics

The product is available in multiple packaging options to suit different shipping 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

Transportation requires strict adherence to safety protocols. The dye must not be mixed with oxidants or edible chemicals. It should be protected from sunlight, rain, and high temperatures during transit. Storage areas must be cool, ventilated, and dry, with temperatures below 25°C and humidity below 75%. Packaging must remain sealed to prevent moisture ingress and oxidation.

Storage and Shelf Life

1. Store in a cool, ventilated, and dry warehouse. Seal packaging during the rainy season.
2. Keep the dye away from sunlight and air to avoid oxidation. Avoid exposure to acids, alkalis, and strong oxidants.
3. Isolate from incompatible substances to prevent deterioration or combustion.

The product has a shelf life of two years under proper storage conditions.
