Xiangyunsha is a traditional Chinese silk fabric known for its earthy tones, soft sheen, and breathable, durable texture. The production process is intricate and deeply rooted in southern China, especially around Foshan and Shunde in Guangdong.
Weaving: The fabric starts with plain-weave silk, often raw or semi-finished.
Dyeing with Dioscorea (yam) juice: The silk is soaked in a dark, starchy paste made from fermented yam or other plant materials, which helps the dye adhere.
Coating with river mud: The fabric is then smeared with local river mud high in iron content. This gives Xiangyunsha its signature color and adds weight and durability.
Sun-drying & oxidization: The mud-coated fabric is repeatedly dried under the sun. The sunlight and mud react with the yam juice in a slow oxidation process, forming the deep brown or bronze-black tones unique to Xiangyunsha.
Washing & polishing: Finally, the fabric is washed clean of mud, softened, and often polished with stones or calendered for smoothness.
This time-intensive method creates a fabric that is naturally antibacterial, mold-resistant, and suited for both clothing and tea textiles—where its ability to age beautifully over time is especially appreciated.
