Indigo Blue Vat Blue - Wuxin Chemical|Textile Dyeing, Quality Standards

Indigo Blue Vat Blue, a dark blue crystalline powder with a rich history in textile dyeing, remains a cornerstone in the production of denim and other textile applications. This article delves into the product specifications, advantages, and industry relevance of Indigo Blue Vat Blue, while exploring its role in modern manufacturing. Additionally, we highlight the company background of Anping County Wuxin Chemical Dye Co., Ltd., a leading supplier in the field.

Product Overview and Key Features

Indigo Blue Vat Blue, also known as Vat Blue 1, is a synthetic dye with the chemical formula C₁₆H₁₀N₂O₂. It is renowned for its deep blue color and exceptional durability, making it a preferred choice for textile industries worldwide. The dye sublimes at temperatures ranging from 390–392°C (734–738°F) and is insoluble in water, alcohol, and ether. However, it dissolves effectively in solvents like DMSO, chloroform, and concentrated sulfuric acid. These solubility properties make it versatile for various industrial applications.

The product is characterized by its dark blue even grains, with a purity of ≥94%, water content of ≤1%, and iron ion content of ≤200ppm. These specifications ensure consistent quality and performance, aligning with international standards for textile dyes.

Applications in Textile Manufacturing

The primary application of Indigo Blue Vat Blue is in the dyeing of light indigo color products, particularly for cotton yarn used in denim fabric. A single pair of blue jeans typically requires 3–12 grams of this dye, highlighting its efficiency and cost-effectiveness. The dye’s unique properties allow for advanced finishing techniques such as stone washing and acid washing, which are critical in achieving the distinctive look of denim.

While denim production is the most well-known use, smaller quantities of Indigo Blue Vat Blue are also employed in dyeing wool and silk. Its resistance to fading and ability to bond with cellulose fibers make it ideal for creating long-lasting, vibrant textiles.

Storage, Transportation, and Shelf Life

Proper handling is essential to maintain the quality of Indigo Blue Vat Blue. The product must be stored in a cool, ventilated, and dry warehouse, with temperatures below 25°C and humidity below 75%. Packaging should remain sealed, especially during the rainy season, to prevent moisture-induced degradation. Exposure to sunlight or air for extended periods can lead to oxidation and reduced effectiveness.

During transportation, the dye must be isolated from oxidants, edible chemicals, and other incompatible substances. Protection from direct sunlight, rain, and high temperatures is mandatory. Light indigo color suppliers emphasize adherence to these guidelines to ensure safe delivery and optimal performance.

The product has a shelf life of two years under proper storage conditions, making it a reliable choice for manufacturers seeking consistent quality over time.

Product Packaging and Logistics

Indigo Blue Vat Blue is available in multiple packaging options to suit diverse logistical needs. Standard configurations include:

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

These packaging solutions ensure efficient transportation and storage, catering to both small-scale and large-scale operations. Light indigo color manufacturers prioritize flexibility and scalability to meet global demand.
