N2 - Protein fibres such as wool undergo severe photodegradation when exposed to sunlight. The photodegradation can manifest as photoyellowing, photobleaching, or phototendering of the exposed fibres. Although the photochemistry of wool is complex, wool photodegradation is a consequence of free radical production and the photooxidation of inherent UV-absorbing and visible chromophores present in the various morphological regions of the fibre. Photo-induced chemiluminescence (PICL) is a sensitive probe to determine free radical populations and their decay rates in irradiated polymers after exposure to UV or visible light in nitrogen, and the subsequent reaction of the primary free radicals with oxygen [1]. This modern technique was used in this study to provide insight on the photodegradation behaviour of wool.
