Yellowing Test Kit

Phenolic yellowing

One of many colour fastness tests, this is a predictive test to assess the potential of white or pastel-coloured yarns, fabrics or garments to yellow (garment yellowing). Our Test Kit is the original, developed by Courtaulds Research, for investigating complaints arising from transit or storage yellowing. Beware of copies and counterfeit products, which do not produce accurate or consistent results or might cause health and safety issues.
