AATCC Test Method 182-2011
Relative Color Strength of Dyes in Solution
Developed in 1998 by AATCC Committee RR98; jurisdiction Transferred to Committee RA36 in 1999
1. Purpose and Scope
This is a test method to determine the color strength of a dye sample relative
to a reference dye by means of spectrophotometric transmittance measurements on
solutions of each. It is a comparison of the color strength of the dyes
in a chosen solvent which may or may not correspond to strengths when applied
to a textile substrate.
2.1 Solutions of the test dye and the reference dye are prepared in known concentrations and their transmittance values are determined using a spectrophotometer. The relative color strength for the test dye is then calculated using absorbance and concentration values.
