Textile artifacts are non-renewable and vulnerable to irreversible damage caused by natural forces, making their effective conservation an urgent necessity. Based on prior damage assessment and scientific analysis, this study conducted an in-depth investigation into the design, tailoring techniques, and craftsmanship of a Qing Dynasty blue-gray python robe made of silk gauze with gold-thread embroidery, providing essential data for the development of a scientific and well-founded restoration plan. According to the principles of cultural heritage conservation and restoration, the parameters for replicating the “double-warp twisted gauze” technique were carefully determined to ensure that the replica fabric closely resembled the original. During restoration, a combined method of backing reinforcement and localized gauze overlay with needlework techniques was applied to the damaged and deteriorated areas, including the collar, horse-hoof cuffs, shoulders and hemline. This approach successfully restored the original structure of the robe, and maintained its stability and ensured its long-term preservation.
