Study On Light Fastness Of Natural Yellow Silk Fabric

In this paper, the light fastness and glossiness of natural yellow silk fabric were analyzed. The test items included the mechanical property, light color fastness, perspiration color fastness, and rubbing color fastness. The relation between the glossiness and different specification of the silk fabric was discussed. Finally, the glossiness of fabric with different degumming rate was observed. The experimental results reveal that the fracture strength of fabric reduces significantly. The fabric's light fastness runs up to 1 similar to 2 degree, perspiration color fastness can reach 5 degree as well as rubbing color fastness. For the 8/5 satin fabric, the glossiness is low. Glossiness of the plain weave is less than the one of the twill fabric. After 48h lighting, the glossiness decreases while the reflectivity increases. When the lighting time increases from 48h to 96h, the glossiness increases gradually. After degumming finishing, glossiness of the fabric decreases, while the reflectivity increases. The fabric can achieve a relatively fine glossiness at degumming rate of 17.34%.
