The objective of this work is to discuss on the luster of silk fabrics from angles of fabric, laundering and ironing. The results indicates that the laundering factors such as the detergent pH, detergent amount, builder, water amount, water temperature, mechanical force of laundering, laundering time and times, and the ironing factors such as ironing temperature, humidity, and pressure cause Interaction among the molecules of the silk. The effect, fiber fibrillation and degradation change the surface state and morphological structure of the fiber, which affect the optical properties of the fabric surface and cause the luster change of the silk fabrics.
