Product Details

Disperse Yellow 54 is a high-purity disperse dye whose chemical structure corresponds to C.I. Solvent Yellow 114. It is supplied as a brown powder and is primarily intended for the coloration of synthetic fibers, particularly polyester. The dye exhibits characteristic disperse dye solubility behavior: insoluble in water, slightly soluble in alcohols, and readily soluble in selected organic acids and solvents under controlled conditions.

In textile applications, Disperse Yellow 54 functions through diffusion and physical entrapment within hydrophobic fiber matrices. It delivers smooth dye uptake and excellent leveling performance during polyester dyeing and printing. The resulting shades are bright, clean, and stable, with particularly strong lightfastness, making the dye suitable for both apparel and interior textile uses. In addition to polyester microfibers, the product can be applied to nylon, acetate, and polyester/wool blends, demonstrating good cross-fiber adaptability.

The dye is compatible with multiple dyeing techniques, including high-temperature high-pressure dyeing, atmospheric dyeing, and carrier-assisted processes. Its color tone is a vivid yellow that can be used alone for solid shades or combined with blue-shade disperse dyes to generate fresh apple-green hues. This versatility makes it a valuable component in disperse dye color-matching systems.

Beyond textile dyeing, Disperse Yellow 54 also finds application as an organic colorant in non-textile fields such as inks, coatings, and plastics, where chemical stability and color strength are required. The product is manufactured under strict quality control to ensure consistent particle size distribution and reliable dispersion behavior, supporting uniform coloration and efficient processing in both dyeing and printing operations.

FAQ

Q: What are the distinctive features or advantages of this series of dyes?

A: The core characteristics of the conventional disperse dye series are balanced performance, universal applicability, and cost-effectiveness. Its primary advantages lie in mature technology, straightforward operation, comprehensive color spectrum, and excellent color blending capability. It delivers stable and reliable dyeing results with outstanding value for money in standard polyester dyeing, serving as the foundational and primary choice for meeting mass-market production demands.

Q: What process is recommended for the application of this series of dyes in textiles?

A: Two main dyeing methods are recommended: high-temperature high-pressure dyeing and hot-melt roll (thermosol) dyeing. Whichever process is applied, a complete reduction washing treatment after dyeing is indispensable to eliminate surface residual dyes and to ensure the required colorfastness of the final product.

Q: How can customers customize packaging dimensions and methods based on their specific requirements?

A: We ship by default in 25kg drums. If customers have specific requirements but are unsure about packaging, they may contact us to discuss their needs. We will provide options for their consideration.
