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

Indigo Blue Vat Blue, also known as Vat Blue 1, is a high-purity synthetic dye that has been a cornerstone of textile manufacturing for centuries. Its unique chemical properties and vibrant color make it indispensable in the production of denim, a fabric synonymous with durability and style. This article provides an in-depth analysis of the product's features, technical specifications, applications, and the company behind its production, Anping County Wu Xin Chemical Dye Co., Ltd..

Product Overview

Indigo Blue Vat Blue is a dark blue crystalline powder with the chemical formula C₁₆H₁₀N₂O₂. It sublimes at a temperature range of 390–392°C (734–738°F) and is insoluble in water, alcohol, or ether. However, it dissolves effectively in solvents like DMSO, chloroform, nitrobenzene, and concentrated sulfuric acid. This solubility profile makes it ideal for industrial dyeing processes, particularly for cotton yarn, which is the primary application for this dye.

Key Features and Advantages

The high purity of Indigo Blue Vat Blue (≥94%) ensures consistent coloration and minimal impurities, which is critical for maintaining the quality of dyed fabrics. Its low water content (

One of the most notable advantages of Indigo Blue Vat Blue is its versatility. While it is predominantly used for cotton yarn in denim production, it is also suitable for dyeing wool and silk, albeit in smaller quantities. The dye's ability to withstand stone washing and acid washing processes makes it a favorite in the fashion industry, where unique textures and finishes are in high demand.

Applications in the Textile Industry

Indigo Blue Vat Blue is the primary dye for cotton yarn, particularly in the production of denim. A single pair of blue jeans typically requires 3–12 grams of this dye, depending on the desired shade and fabric thickness. Its ability to bond with cellulose fibers in cotton ensures deep, even coloration and resistance to fading.

The dye's role extends beyond denim. In the wool and silk industries, it is used to achieve rich, vibrant blue tones. Additionally, its chemical stability allows it to be used in specialty applications, such as the dyeing of leather and paper, where durability and colorfastness are essential.

According to the National Institute of Standards and Technology (NIST), the precise measurement of dye purity and solubility is critical for ensuring consistency in industrial applications. The standards outlined in the NIST Guide to the SI provide a framework for evaluating the quality of such chemical products, underscoring the importance of rigorous testing and compliance with specifications.

Packaging and Logistics

The product is available in multiple 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.

For suppliers and factories, these packaging options ensure flexibility in logistics, reducing costs and minimizing waste during transportation.

Storage and Handling Guidelines

Proper storage 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%. During the rainy season, the packaging must be completely sealed to prevent moisture absorption, which can lead to degradation.

Key storage precautions include:

1. Keep the dye away from sunlight and air to prevent oxidation and deterioration.
2. Store it isolated from acids, alkalis, strong oxidants, and reducing agents to avoid chemical reactions.
3. Ensure no exposure to fire, heat sources, or high-temperature areas during transportation and storage.
