Abstract

Since leather is strongly affected by three main environmental parameters – temperature, relative humidity, and UV radiation – this study focuses on the effect that these three factors have on wet-bright leather ageing. Wet-bright leathers were exposed to weathering effects in a climatic chamber to 1) try and identify the major variables affecting this weathering process; and 2) check for any possible interactions among these variables. Both a multilevel centralized factorial experimental design and an analysis of variance (ANOVA) were used as statistical tools for estimating the effects of the parameters.
