摘要：

Wool has been examined by microspectrofluorimetry. Single merino fibres show a decrease in fluorescence intensity along the length of the fibre from tip lo root, with similar fluorescing species present throughout the fibre. With fabric, oxidative bleaching caused an increase in fluorescence intensity, whereas laser-blue-light irradiation caused a decrease. A decrease was also found when fabric embedded in immersion oil or glycerol was irradiated with UV radiation. When bleached and unbleached wools were separated into their morphological components (cuticle, cortex, and cell-membrane complex), similar fluorescing species were found. From preliminary measurements, the fluorescent species appears to be most heavily concentrated in the cortex.
