The photobleaching of wool, using the 488nm line of an argon ion laser and north light fluorescent lamps, in wet and dry states, has been studied. Destruction of the chromophores absorbing in the visible wavelength region was accompanied by a modest increase in UV-absorbing chromophores. Use of north light lamps resulted in little change in the natural fluorescence, whereas irradiation with the 488nm laser line caused a decrease. UV irradiation of wool using either the 351nm line of the argon ion laser or UV fluorescent lamps led to extensive yellowing, manifested by an increase in both visible- light- and UV-absorbing chromophores, and this was generally accompanied by a marked increase in natural fluorescence. The wool yolk has a definite protective effect upon UV irradiation of wool but no effect was observed upon north light irradiation.
