Phenolic yellowing affects natural and synthetic fibers. The phenolic antioxidants present in the packing material along with exposure to oxides of nitrogen and alkali pH of the fabric are responsible for yellowing. The Phenotest assesses the potential of phenolic yellowing of textile materials. Performing this test will
help manufacturers understand and predict if a garment will yellow while in its package, in transit and in storage. Phenolic yellowing is a discoloration phenomenon in textiles caused by the reaction of nitrogen oxides with yellowable phenolic compounds, often resulting in unsightly yellow stains on white or light-colored fabrics. BHT is widely used in polyethylene bags. During storage or transport, BHT can migrate from the packaging to the fabric surface. Nitrogen oxides from combustion react with BHT to form yellow-colored compounds. Testfabrics Phenotest Glass Plates are part of the test apparatus used to carry out phenolic yellowing tests.

Testfabrics Phenotest impregnated test papers are soaked in a methanol solution containing phenolic chemicals that can cause yellowing in textiles. The phenolic compounds in the paper act as a controlled source of yellowing agents, simulating the effect of phenolic substances (such as certain antioxidants like BHT) migrating from the material into the paper. When the test paper is placed in contact with a fabric sample under standardized conditions (e.g., in a Perspirometer at 50 °C for 16 hours), any yellowing of the fabric indicates that the fabric has the potential to yellow under similar conditions.
