Photoreactivity of Wool Dyed with Reactive Dyes

Presented at the 13th Congress of the International Federation of Associations of Textile Chemists and Colourists in London on 20th September 1984. Processes (Photodegradation) induced by two kinds of illumination (ultra-violet and Xenotest) in wool dyed with reactive dyes have been investigated as a function of time. The fading of dyed fibres has been determined in terms of the conditions of illumination. The degradation of wool was followed on the basis of changes in alkali solubility and tensile characteristics. Moreover the colour change of the dyed fibres was also determined
