TFPF-25 BHT-free Phenotest Plastic Film, 400mm x 200mm, pack of 25 pieces
$19.00 / Pack
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 BHT free film is used as a blank control in the phenotest, to wrap test samples.
Description
BHT (Butylhydroxytoluene) is a common antioxidant in polyethylene films. If present, BHT can cause yellowing itself, leading to false positive results. By using BHT-free film, the test ensures that any observed yellowing is due to the textile sample’s phenolic content, not the packaging material.
