A comparative study on accelerated weathering tests of wool fabrics
journal contribution
posted on 2008-01-01, 00:00 authored by H Zhang, Peter Cookson, Xungai WangThis work has used two lightboxes with Philips 500 W MBTF lamps for a comparative trial on the photoyellowing evaluation of untreated wool fabrics under dry and wet conditions. An investigation was made to account for different trends of photoyellowing of the same wool fabric when irradiated by the two lightboxes. The fabric specimens irradiated in one lamp experienced increasing yellowing with irradiation time while specimens from the same wool fabric but irradiated under the other lamp manifested no noticeable color change. These differences are attributed to the susceptibility of wool to small spectral differences between the two MBTF lamps. Furthermore, the color fading results obtained from the commonly used blue wool standard (BWS) references from L1 to L3 show that these reference materials could not effectively reveal changes caused by the spectral differences in two MBTF lamps. These results have important implications for conducting accelerated weathering tests on spectrum-sensitive textile materials, and considerable care should be taken when using BWSs to ensure reliable and consistent irradiation results.
