Indigo Blue Vat Blue - Wuxin Chemical | Textile Dye, Denim, Cotton

Introduction

Indigo Blue Vat Blue, a dark blue crystalline powder with a rich history in textile dyeing, continues to be a cornerstone in the production of denim and other cotton-based fabrics. This article delves into the Indigo Blue Vat Blue product, exploring its technical specifications, applications, packaging details, and the company background of Anping County Wuxin Chemical Dye Co., Ltd.. Whether you're a textile manufacturer, a chemical supplier, or a researcher, this guide provides essential insights into the properties and uses of this iconic dye.

Product Overview

Indigo Blue Vat Blue, also known as Vat Blue 1, is a high-purity dye with a chemical formula of C₁₆H₁₀N₂O₂. It is renowned for its dark blue color and durability, making it ideal for applications requiring long-lasting color retention. The product is available in granular form, ensuring ease of handling and consistent performance in industrial settings.

As a vat dye, Indigo Blue Vat Blue is insoluble in water but dissolves in specific solvents such as DMSO, chloroform, and concentrated sulfuric acid. Its unique chemical properties allow it to bond effectively with cellulose fibers, making it a preferred choice for denim and blue jeans production. The sublimation point of this dye is 390–392°C, reflecting its thermal stability under industrial conditions.

Technical Specifications

The high purity of Indigo Blue Vat Blue ensures minimal impurities, enhancing its color consistency and performance. The low water content and controlled iron ion levels further contribute to its stability and resistance to degradation during storage and transportation.

Key Features and Advantages

Indigo Blue Vat Blue offers several advantages that make it a preferred choice for textile manufacturers:

• Exceptional Colorfastness: The dye provides long-lasting color retention, even after repeated washing and exposure to sunlight.
• Compatibility with Cellulose Fibers: Its ability to bond with cotton and cellulose-based fabrics ensures uniform dyeing and minimal color bleeding.
• Resistance to Oxidation: Proper storage conditions prevent oxidative degradation, maintaining the dye's efficacy over time.
• Cost-Effectiveness: With low usage rates (3–12 grams per pair of jeans), it offers economic efficiency for large-scale production.

These features make Indigo Blue Vat Blue an essential component in the textile industry, particularly for denim and blue jeans manufacturing. Its versatility also extends to wool and silk dyeing, albeit in smaller quantities.

Applications and Industry Use Cases

The primary application of Indigo Blue Vat Blue is in the dyeing of cotton yarn, which is then used to produce denim fabric for blue jeans. A single pair of jeans typically requires 3–12 grams of this dye, highlighting its efficiency and cost-effectiveness

Indigo Blue Vat Blue is also utilized in stone washing and acid washing processes, which create distinctive textures and visual effects on denim. These techniques rely on the dye's chemical stability and compatibility with cellulose fibers. Additionally, the dye's resistance to fading makes it suitable for high-traffic textiles such as workwear and apparel.

For smaller-scale operations, the dye is used in wool and silk dyeing, where its color depth and uniformity are highly valued. This versatility underscores its importance in textile innovation and product development.

Packaging and Logistics

Indigo Blue Vat Blue is available in multiple packaging options to suit various logistical needs:

• 20kg Cartons: 9 metric tons (without pallet) in a 20’GP container111, or 18 tons (with pallet) in a 40’HQ container111.
• 25kg Bags: 12 metric tons in a 20’GP container111, or 25 metric tons in a 40’HQ container111.
• 500–550kg Bags: 20–22 metric tons in a 40’HQ container111.

The flexible packaging options ensure efficient transportation and storage. However, it is strictly prohibited to mix and transport this product with oxidants or edible chemicals to prevent chemical reactions and contamination.

Storage and Transportation Guidelines

To maintain the quality and stability of Indigo Blue Vat Blue, the following storage and transportation guidelines must be followed:

1. Storage Conditions: Keep the product in a cool, ventilated, and dry warehouse. The temperature should be below 25°C, and the relative humidity should be below 75%. During the rainy season, ensure the packaging is completely sealed to prevent moisture ingress.
2. Protection from Environmental Factors: Avoid sunlight, rain, and high temperatures during transportation. If stopping over, stay away from fire, heat sources, and high-temperature areas.
3. Isolation from Incompatible Substances: Store the dye separately from acids, alkalis, strong oxidants, and reducing agents to prevent degradation or combustion.

These measures ensure the longevity and performance of the product, aligning with industry standards and regulatory requirements.
