Test Method: SATRA TM260

Phenolic (elusive) yellowing of textiles

September 2009


This method is intended to assess the potential of materials to yellow due to contamination by sterically-hindered phenols, which are contained in some packaging. Although textiles and PU materials are more sensitive to yellowing from these anti-oxidants, this method is applicable to all white and pastel-coloured materials.


A test specimen is placed in contact with an impregnated paper, sandwiched between glass plates and wrapped completely in polythene. This assembly is stored in a warm environment for a set time. Immediately after this period, the change in colour of the test specimen is assessed subjectively with grey scales.
