Lustre from use Lustre from use or “mirror in a seat” results from the pile of velvety materials, such as velour, chenille and possibly microfibres, being flattened during use, thus producing a different appearance when light falls on it, e.g. a light and dark effect. This is not a material defect in the product but a material feature typical of the product. This visual change does not affect use, function or product life and is a typical characteristic. Lightfastness RAL 430/3 A cover’s resistance to the effects of light (especially sunshine, daylight and halogen lighting) are described as lightfastness. Discolouration of the material from the effects of light cannot be prevented with upholstery covers. The sun’s elemental force alters all materials! Special care is therefore called for in rooms with a large amount of light and glass. Especially when the sun is shining, curtains or blinds should be drawn, as direct sunlight can change the colour of cover materials even after a few weeks. |
