AATCC 146 Test Method for Dispersibility of Disperse Dyes: Filter

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of the AATCC 146 test. This test determines the dispersion of disperse dyes under standard conditions in aqueous media, evaluated by filtering time and filter residue.

AATCC (American Association of Textile Chemists and Colorists) Test Method 146 is used to evaluate the dispersibility of disperse dyes using a filter method. Disperse dyes are a class of dyes used primarily for coloring synthetic fibers such as polyester, acetate and nylon. Dispersibility refers to the ability of these dyes to completely dissolve and disperse in a given environment, typically a solvent or water.

Disperse dye samples to be tested are prepared. Samples can be in powder or granule form and are typically weighed and measured to provide a consistent starting point for testing.

The dispersion is filtered through a filter membrane typically made of a specific material with a defined pore size. This filtration step is designed to evaluate the ability of the dye to pass through the filter and disperse without clogging or forming clumps.

Test results are reported to show the dispersibility of the disperse dye in the specified environment. This information can be important for dye manufacturers, textile manufacturers and quality control personnel to ensure that disperse dyes are suitable for their intended applications and do not cause problems such as uneven dyeing or staining.

AATCC Test Method 146 is an important tool for evaluating the quality and performance of disperse dyes in the textile industry. This helps determine how well paints disperse in the intended application environment; This is critical for uniform and reliable dyeing of synthetic fibers.
