Manufacturing Process Flow of Indigo Blue Granular Products

The production of high-grade indigo blue granular products by a reputable indigo blue granular company involves a meticulously controlled multi-stage process, ensuring purity, consistency, and optimal performance. Our manufacturing leverages advanced chemical synthesis and granulation technologies to meet stringent international standards.

Detailed Process Steps:

1. Raw Material Sourcing & Pre-treatment: High-purity aniline, formaldehyde, sodium cyanide, and potassium hydroxide are carefully sourced. These are subjected to strict quality checks to ensure compliance with our internal material specifications.
2. Phenylglycine Synthesis: Aniline and formaldehyde react to form an intermediate, which then undergoes further reaction with sodium cyanide to produce phenylglycine. This is a critical step, requiring precise temperature and pressure control.
3. Fusion & Cyclization (Indoxyl Formation): Phenylglycine is fused with a strong alkali (e.g., potassium hydroxide) at high temperatures. This molten mixture undergoes cyclization, forming indoxyl. This reaction, known as the Heumann-Pfleger synthesis or a similar variant, is central to indigo formation.
4. Oxidation & Indigo Formation: The indoxyl melt is then dissolved in water and exposed to air (oxygen). This oxidation process leads to the dimerization of indoxyl, forming the vibrant blue indigo pigment. Control of pH and aeration rate is crucial for optimal yield and purity.
5. Purification & Filtration: The crude indigo suspension undergoes multiple washing and filtration steps to remove impurities, unreacted starting materials, and by-products. Pressure filtration and membrane separation techniques are employed to achieve high purity levels.
6. Drying & Milling: The purified indigo filter cake is dried using specialized dryers (e.g., spray dryers or fluid bed dryers) to achieve a desired moisture content. The dried material is then milled to a specific particle size, which influences its subsequent granulation.
7. Granulation: The finely milled indigo powder is then processed through a granulation unit, typically using fluid bed granulation or extrusion granulation. A binding agent is often added to facilitate the formation of uniform, robust granules. This stage significantly improves product handling, reduces dusting, and enhances dissolution properties.
8. Quality Control & Testing: Throughout the entire process, samples are taken at critical junctures for comprehensive testing. Final product batches undergo extensive analysis, including color strength (ISO 105-J01), shade consistency, moisture content, particle size distribution, and fastness properties (ISO 105-B02, ISO 105-C06). Only products meeting the highest standards are approved.
9. Packaging & Dispatch: Approved granular indigo is packed into appropriate industrial container111s, often moisture-resistant bags or drums, labeled with batch details, and prepared for dispatch to our global clientele.

Our manufacturing facilities adhere to ISO 9001:2015 quality management systems and ISO 14001:2015 environmental management standards, ensuring both product excellence and sustainable practices. The service life of our dyes, once applied correctly, aligns with industry expectations for the longevity and colorfastness of the dyed substrate.

Target Industries & Application Advantages:

Our indigo granular products are primarily supplied to the:

• Textile Manufacturing Industry: Especially for denim and casual wear, where vibrant, long-lasting blue shades are essential. The granular form offers superior dispersion, leading to fewer speckles and more uniform dyeing.
