Study on the Color Fastness to Light of the Natural Fiber Fabric

In order to understand the color fastness to light of the natural fiber materials, different kinds of natural fiber fabrics were tested for comparison. Based on the data obtained from the experiments, a conclusion was drawn that the degree of color fastness to light could be divided into different levels and there were many factors that can affect the color fastness to light, such as fiber materials, dye, color combinations, atmospheric compositions of surroundings, sample moisture content ratio, temperature and so on. This paper carries out the original methods including dyeing and exposing to light and it also provides some guides for the researches on color fastness of the natural fiber materials.
