Woven gold brocade in the Yuan Dynasty, as a combination of northern and southern elements in Chinese history, and embodiment of material culture of integration of China and the West, is unique and creative. In recent years, with the rise of the national tide in cultural and creative field, ancient traditional clothing has gradually entered the public eye, and more and more classic elements of clothing have been applied to modern design. The woven gold brocade in the Yuan Dynasty experienced origin, development and decline, but related research has stagnated in recent years. Commissioned by Changzhou Hongyang Textile Museum, we developed a standardized restoration process through literature review, and proceeded technical restoration of “Square Diamond Dark Flower Silk with Plum Blossom and Finch Patterns” unearthed from Li Yu’an Tomb of Zou county in the Yuan Dynasty.First of all, the unearthed fabric was defined according to the characteristics of Nasich and Jinduanzi. Nasich is mostly made by officials, the output is small, and the layout is also mostly exposed to the surface of the gold thread flower part. Its pattern style retains a strong Western style, such as birds, beasts, dragons, fishes, even Arabic characters, which are symmetrical, orderly and complex, and highly patterned, reflecting the admiration of the Mongolian royal family for Islamic civilization. Jinduanzi is mainly combined with Chinese characteristics, and the pattern theme reflects the combination of Han and nomadic civilization, such as bird pattern, flower pattern and ancient traditional auspicious pattern. Considering the description that “the padded robe with a plum pattern seems to be a civil servant robe”, we inferred that Li Yu’an was probably an official in Zou county, with a low rank in terms of county education and teaching instruction. In the meanwhile, the “plum blossom” and “finch” in “Square Diamond Dark Flower Silk with Plum Blossom and Finch Patterns” are typical elements of Han culture. Combined with the identity of the tomb owner, the unearthed fabric is preliminarily determined as “Jinduanzi”.The specific restoration process refers to the graphic cross-proof method, literature reference method and physical inspection method, including color verification, pattern verification, material verification and technical verification. After color determination, drawing, material selection and weaving, the restoration process is completed. Based on the color research and the description of ancient literature, it is inferred that the pattern is a basic two-yarn-dyed woven gold brocade in the Yuan Dynasty. The background is brown, while the plum blossoms, branches and finches are bright gold. According to the original size of the real pattern, the pattern was restored in equal proportion. Combined with the relevant requirements of weaving, the pattern was determined to be of a square continuous cycle with a size of 22.5 cm×22.5 cm. Photoshop was used to describe the pattern and make the pattern cycle. By comparing the difference between the “twisting gold method” and the “slice gold method” in material research, it is concluded that the pattern is more likely to be made of gold thread by twisting gold method. Due to the limitations of gold thread production at that time, the thinness requirements could not be met technically, so fineness of the weft of the woven gold brocade was generally thicker than that of the warp. In the process research, the weave of the restored fabric is “satin”. As a chest coat, it not only guarantees high durability, but also reflects its luxurious style. In addition, the pattern is arranged in full width, and the pattern on the surface with gold is obvious, indicating typical shuttle picking method. Fabric restoration has gone through warping, warp threading, weaving and other processes, and attention should be paid to the adjustment of process-related parameters in the practice. We then used fuzzy evaluation method to complete the restoration evaluation. The results showed that 30% of the evaluators believed that the restoration effect was “average”, 57% believed that the restoration effect was “good” and 13% held that the restoration effect was “very good”. According to the principle of maximum membership, the recovery effect of woven gold brocade is considered to be “good”. The practice shows that the visual object of woven gold brocade can be made by the combination of traditional archaeological perspective with modern textile technology. In this study, we restore woven gold brocade in the Yuan Dynasty by combining cultural research with modern textile technology, which can deeply analyze its historical connotation, artistic characteristics, textile technology and other aspects, contribute to the full understanding of the integration and evolution of this special cultural heritage with the changes of the times, and exploring the mutual relationship between traditional archaeology and contemporary science and technology, so as to provide a new research perspective for the carrier transmission of woven gold brocade culture.
