报告题目：Improving the Whiteness and Photostability of Wool

报告摘要：In terms of its achievable whiteness compared to cotton and synthetic fibres, wool compares poorly. Wool remains cream in colour even after bleaching, whereas cotton and synthetic fibres are bright and white. Current commercial bleaching of wool relies exclusively on the use of hydrogen peroxide, which is relatively inefficient on wool compared to other fibres, and also reduces wool’s photostability. Although fluorescent whitening agents can be applied to bleached wool to produce a much whiter base fabric, they are seldom used due to the extreme rate of photoyellowing of the treated wool, particularly when wet.

He has achieved international recognition for his work on fibre and polymerphoto chemistry and coloration, leading a team carrying out research into the processes that occur when materials are exposed to radiation, in particular the generation and reactions of free radicals. Awarded the Centenary Medal (2008) by the Society of Dyers and Colourists for his extensive review on the yellowing of wool keratin published in Coloration Technology. Gold Research Medal (2003) awarded by The Worshipful Company of Dyers in London, with Prof Louis Kirschenbaum of the University of Rhode Island for work on the theory of wool photoyellowing. Winner of Innovative Technology Award at the Radtech '96 North America conference in Nashville, Tennessee for paper on application of Siroflash UV technology to textiles.
