Abstract
The purpose of this study was to investigate the changes in properties of silk fabrics dyed with safflower red and yellow colorants under Ultraviolet(UV)-light. Silk fabrics dyed with safflower red and yellow colorants were compared with each other after uv-light exposure in terms of K/S value, color changes(${\Delta}E$), morphology, and strength retention. The K/S value rapidly decreased with increasing exposure time for samples of both colorants, but the extent of decrease was less for the samples dyed with safflower yellow colorant, than that of the samples dyed with safflower red colorant. Regarding the color changes with increasing exposure time, $L^*$ and $b^*$ increased, $a^*$ decreased, and thereby ${\Delta}E$ increased in the red-dyed samples, whereas $L^*$ increased, $a^*$ and $b^*$ decreased, and so ${\Delta}E$ increased in the yellow-dyed samples, indicating that the UV-light induced fading and changes of hue, value and chroma value. However, the color change of the yellow-dyed samples was less than that of the red-dyed samples. SEM images showed a severe degradation by UV-exposure for both colorant samples. Tensile strength slowly decreased until 14 days, but rapidly decreased thereafter. Strength retention of the yellow-dyed samples was higher than that of red-dyed samples.
