In the vibrant world of textile coloration, the selection of precise chemical intermediates is crucial for achieving desired shades and performance characteristics. Naphthol AS-OL, identified by CAS number 135-62-6, plays a significant role as a base agent in the textile dyeing industry. This article, from the perspective of a leading Chinese manufacturer and supplier, highlights the importance of Naphthol AS-OL and how textile professionals can effectively source this key intermediate.

Naphthol AS-OL, also known by its chemical name N-(2-Methoxyphenyl)-2-hydroxy-3-naphthamide, is typically supplied as a fine beige powder with a purity of 99% or more. Its primary function in textile dyeing is as a coupling component in the azoic dyeing process. This method involves impregnating the textile fibers first with a diazonium salt, followed by treatment with Naphthol AS-OL. The subsequent reaction forms an insoluble azo dye directly within the fiber matrix, resulting in excellent wash fastness and brilliance.

The applications of Naphthol AS-OL are extensive, particularly for cotton, silk, viscose, and diacetate fabrics. It is instrumental in producing a spectrum of bright colors, often reds, oranges, and browns, when combined with appropriate diazo components. The characteristic beige powder form ensures ease of handling and dissolution during the dyeing process. For textile manufacturers aiming to achieve high-quality, durable coloration, sourcing high-purity Naphthol AS-OL is a non-negotiable step.
