Light fastness testing is a specific type of Colour Fastness Testing, where its purpose is to subject your test samples to intense artificial light to assess the impact on the material.
Of all the types of colour fastness testing, gauging a material’s reaction to light is probably one of the most important. How fabrics perform during washing, dry-cleaning, rubbing, perspiration; or following exposure to different kinds of water, is, of course, vital information for manufacturers. But the effects of light can be far more subtle and unpredictable, so it’s here that accurate, reliable testing is crucial.
At a commercial level, light fastness testing gives manufacturers confidence in their products. It helps them extend ranges, enter new markets, and develop innovative materials ahead of their competitors. It also enables them to meet national, international and retailers’ standards.
Light fastness is one of the most common topics that our customers seek help and support for, particularly for how to interpret and visually assess the results of a light fastness test.
To help with this complex area of textile testing, we sat down with Peter Goodwin, one of our most experienced Technical Specialists in the area of light fastness testing, to ask him for his advice around what the key challenges of light fastness testing are, and how to avoid the most common complications.
