Abstract
In this first part of a continuing project, the tear strength and degree of polymerization of plain woven cotton fabric exposed to the light of a xenon arc lamp, with and without filters, at temperatures from 32 to 56°C and relative humidities between 30 and 75% were measured. Pseudo first order reaction rate constants and activation energies derived from these measurements indicate that the mechanisms of photodegradation are quite different from those encountered in heat aging. The mechanisms of photodegradation, the role of moisture, and the significance of this study for the practice of textile conservation are considered.
