At NINGBO INNO PHARMCHEM CO.,LTD., we understand the intricate processes involved in textile coloration. Naphthol AS, identified by its CAS number 92-77-3, stands out as a cornerstone chemical intermediate, particularly vital for the cotton dyeing industry. Its unique properties as a coupling agent allow for the creation of rich, durable colors on cotton fibers, a feat that has been essential for textile manufacturers for decades.

The application of Naphthol AS in cotton dyeing is multifaceted. Primarily, it acts as a primer, preparing the fabric for subsequent dyeing steps. When combined with specific diazo components, it forms insoluble azo dyes directly within the fiber, leading to excellent wash and light fastness. This characteristic makes it an indispensable component for achieving high-quality finishes that consumers expect. The ability to achieve a wide spectrum of colors, from vibrant reds to deep blues, by simply varying the diazo component, highlights the versatility of Naphthol AS.

We consistently focus on supplying Naphthol AS with a high purity level, typically 99%, ensuring that our clients receive a product that guarantees predictable and superior dyeing performance. The technical specifications, such as a melting point of 246.5°C, are critical for handling and processing, and we ensure our product meets these stringent requirements. Our commitment as a supplier in China is to provide a chemical intermediate that not only meets but exceeds industry standards, thereby empowering our customers to produce world-class dyed textiles.

Beyond traditional dyeing, Naphthol AS finds application in textile printing as well. Its ability to form stable colored compounds makes it suitable for printing pastes, allowing for intricate designs and patterns on fabrics. The effectiveness of Naphthol AS in these applications contributes significantly to the aesthetic appeal and market value of finished textile products. For businesses looking to source high-quality Naphthol AS, exploring the benefits of working with a dedicated China manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. can ensure a reliable supply chain and consistent product quality, crucial for maintaining competitive pricing and efficient production schedules.
