About This Product
Colour fastness to light is checked by exposing a textile specimen to daylight alongside a set of light fastness standard fabrics numbered 1 to 8, until the desired fading is obtained. The colour change of the exposed area on the specimens and on the standard fabrics is then examined, and the relative degree of colour fastness of each specimen is determined. The rack holds the mounted cards in the open at a fixed tilt under a glass lid, which suits textile and dyeing practicals. The Exposure Rack can be supplied for export orders from Serbia, Sierra Leone, Guyana, Eswatini and Kyrgyzstan.
