For professionals in the textile industry, selecting the right dye intermediates is paramount to achieving consistent, high-quality results. Acid Yellow 17 (CAS 6359-98-4) is a cornerstone dye intermediate, prized for its vibrant yellow hue and excellent performance on various fibers like wool, silk, and nylon. However, the efficacy of this dye is heavily dependent on the quality and consistency provided by its supplier. This guide will help you navigate the critical factors when choosing an Acid Yellow 17 manufacturer or supplier, ensuring you secure the best product for your dyeing operations.

Understanding Your Needs: Key Specifications of Acid Yellow 17

When you look to buy Acid Yellow 17, understanding its typical specifications is the first step. Reliable suppliers will readily provide detailed technical data. Key parameters to scrutinize include:

  • Strength: Look for products with consistent strength, often around 120%±＜2%. This indicates the concentration of the active dye component, directly impacting your cost-effectiveness and color matching.
  • Shade: The shade (e.g., CMC2:1 ≤0.5) is crucial for achieving the precise hue you require. Variations here can lead to batch-to-batch color differences, a significant concern for brand consistency.
  • Solubility: High solubility (e.g., ≥70g/l at 90℃) ensures the dye dissolves easily in the dyebath, leading to uniform application and preventing issues like speckling or uneven dyeing.
  • Purity: Low moisture (≤8%) and insolubles (≤0.2%) are indicators of a high-purity product, minimizing potential contaminants that could affect the dyeing process or the final fabric quality.
  • Physical Form: Typically supplied as a yellow powder, the fineness (≤8%) of the powder also plays a role in its dispersion and dissolution characteristics.

Why Partner with a Reputable Manufacturer and Supplier?

Sourcing Acid Yellow 17 from a dependable manufacturer, especially one based in China known for its chemical production capabilities, offers distinct advantages. A good supplier will not only provide high-quality materials but also ensure stability in pricing and supply.
