Light fastness refers to the degree of discoloration of fabrics by sunlight. The test method can be either by sunlight or in a sunlight simulation machine.
After exposure, the testing sample will be compared to the standard color sample. If the performance is not well enough, it should not be regularly exposed under sunlight.
Thus, light fastness is an essential parameter for window covering products.
