An example of the spread of Chinese culture, Western parasols of the 19th—20th century, was mostly made of silk, with the handle being of ivory or other materials. The manufacturing process was characterized by the integration of Chinese and Western cultures. Thus parasols represent an important example of cultural exchange between the East and the West. At present, there are few studies and examples of parasol restoration in China. In our research, we took a 19th-century Western silk parasol collected in Hangzhou Arts and crafts Museum as an example. We carried out nondestructive analysis of fabric material and structure using a portable microscope and a near-infrared spectrometer. Restoration of the parasol was completed through technological research, production of support, parasol surface removal, leveling, restoration and assembly of the parasol surface. This paper is focused on the study of the shape decomposition of the restoration of parasol and the method for making the restoration mold, which is the key to the restoration of parasol and could provide a practical reference for the scientific restoration and protection of such cultural relics.
