Evaluation of Fabrics Colour Fastness According to the Ecolabel Criteria

The present work is focused on evaluation of the colour fastness (to washing, perspiration, wet and dry rubbing, and light exposure) of dyed workwear fabrics (in red, blue and gray colours) – labeled and unlabeled with Ecolabel, with the purpose of indicating the low setting of minimum quality requirements and the need for more precise defining of colour fastness assessment method within the Ecolabel fitness for use criteria. Comparison of visually and instrumentally obtained gray scale grades based on spectrophotometrically determined CIEL*a*b* colour parameter differences have been carried out.
