Xiangyunsha silk is shaped by plants, earth, water, and sunlight. It begins with pale mulberry silk. It leaves the dyeing field with two natural colors, a subtle glow, and a crisp hand.
The traditional craft is often summarized as Three Steams, Nine Boils, and Eighteen Sun-Dries. Every stage is completed by hand. The process cannot be rushed or completed in a different order.
Where Does Xiangyunsha Come From?
Xiangyunsha comes from Foshan City, Guangdong Province. The wider Pearl River Delta also played an important role in its development. Today, Shunde remains a major center for the traditional craft.
The region offers the right natural conditions. There is plenty of sunlight, open grasslands, clear waterways, and unique river mud. These elements are essential to traditional production.
Historical records show that dioscorea juice was used as a natural dye in ancient China. Xiangyunsha silk was already exported during the Yongle period of the Ming Dynasty. By the early twentieth century, Shunde had hundreds of Xiangyunsha workshops.
In 2008, the Xiangyunsha dyeing and finishing technique entered China’s second national list of intangible cultural heritage. China Intangible Cultural Heritage Network
Xiangyunsha is also linked to the older name Xiangyun Sha, or “rustling cloud gauze.” Finished garments were made like a soft rustling sound during movement. Over time, the name evolved into the modern term Xiangyunsha.
The Four Natural Materials
Traditional Xiangyunsha depends on four main materials:
- Mulberry silk forms the base of the fabric.
- Dioscorea cirrhosa, supplies the plant dye.
- Mineral-rich Shunde river mud creates the dark surface.
- Sunlight develops and fixes the natural color.
Dioscorea contains a high level of tannins. The river mud contains iron compounds. Their reaction creates the famous dark surface of the fabric.
The traditional method uses no synthetic dyeing mordants. Weather, water, mud, and the artisan’s experience control the final result.
How Xiangyunsha Silk is Made
The complete process includes many repeated treatments. Some workshops describe it as 14 main techniques and more than 30 manual operations.
The central standard is Three Steams, Nine Boils, and Eighteen Sun-Dries. Steaming, boiling, dyeing, and sun-drying are connected. They form a repeated production program rather than three unrelated blocks.
Step 1: Prepare the Silk
Artisans first inspect the undyed mulberry silk. The cloth must be even and free from damaged threads.
The silk is washed and prepared to accept the natural dye. It is then stretched, smoothed, and dried.
Step 2: Prepare the Dioscorea Dye
Fresh Dioscorea (shuliang tubers) are cleaned and crushed. They are soaked or heated in water to release their tannin-rich juice.
The liquid is filtered to remove plant fibers. Artisans prepare dye baths of different strengths. Concentrated liquid starts the color. Lighter liquid is used during later treatments.
Step 3: Complete the First Dye Bath
The silk is immersed in concentrated shuliang liquid. Every part of the fabric must absorb the dye evenly.
The wet silk is lifted, drained, and smoothed. It is then spread flat on grass. Bamboo poles may be used to keep the lightweight cloth in position.
This first treatment gives the silk a pale amber tone.
Step 4: Build the Color
The fabric now enters the core cycle of Three Steams, Nine Boils, and Eighteen Sun-Dries.
- During the Three Steams, moist heat is applied at key stages. The artisan controls the temperature and moisture by experience.
- During the Nine Boils, the silk is gently heated in carefully prepared shuliang liquid. The cloth is drained and smoothed between treatments.
- During the Eighteen Sun-Dries, the fabric is spread flat under the sun. It is turned, checked, and treated with more dye when required.
Each repetition adds another thin layer of color. The silk gradually changes from pale gold to amber, brown, and deep reddish brown.
Sunlight must be strong but not excessive. Rain can cause uneven color. Extreme heat can make the silk hard or brittle. For this reason, traditional production follows the seasons.
The process is known as shai liang, or sunning the gambiered silk. Chinese National Geography describes the importance of repeated sunlight, while Our China Story explains how the wet and dry treatments are repeatedly combined.
Step 5: Roll and Rest the Silk
Once the brown base is deep enough, the cloth is rolled evenly. This keeps its surface smooth and ready for the mud treatment.
The silk may rest before the next stage. The artisan checks its color, moisture, and flexibility.
Step 6: Apply the River Mud
The next stage is called guo wu, or “passing through black.”
Fine river mud is spread over one side of the silk. The layer must be thin and even. Uneven mud would create unwanted marks.
Iron compounds in the mud react with tannins from the dioscorea dye. The covered side becomes glossy black. The other side keeps its warm brown or reddish-brown color.
The mud must be removed before it dries completely.
Step 7: Wash and Seal the Fabric
The silk is washed carefully to remove all visible mud. It is then spread out and dried again.
A final light treatment of shuliang liquid may be applied. This stage balances the color and completes the natural surface.
Step 8: Sofetern the Silk with Evening Moisture
The fabric is spread flat during the evening or early morning. It absorbs gentle moisture from the air and grass.
This stage is called tan wu. It helps relax the fabric after repeated heat and sunlight.
Step 9: Stretch, Rest, and Inspect
Artisans stretch the silk back to its proper width. They smooth the surface and inspect both sides.
Some traditional cloth needs to be left to rest for several months before its final wash and finishing. The finished material is then ready for cutting.
The entire process depends on the artisan’s judgment. Sunlight, wind, temperature, and humidity change each day. This is why no two pieces are completely identical.

What Makes Xiangyunsha Special?
Two Natural Colors
Traditional Xiangyunsha has a glossy black face and a warm brown reverse. Both colors come from natural dyeing and mud finishing.
A Cool, Breathable Feel
The silk is light and breathable. It does not cling closely to the skin. This makes it comfortable in hot and humid weather.
Crisp Yet Flexible
New Xiangyunsha has a clean structure and a slightly crisp hand. It holds the shape of a garment well without feeling heavy.
Durable and Practical
The fabric is colorfast, resistant to light splashes, and quick-drying. Its deep surface also hides small marks better than pale silk.
Natural Variations
Small changes in color and texture are normal. They record differences in sunlight, grass, mud, and handwork. These variations are part of authentic hand-dyed Xiangyunsha silk.
Why Does Xiangyunsha Become Softer with Wear?
A new piece of Xiangyunsha may feel firmer than ordinary silk. This comes from the many layers of dioscorea dye and the dark mud-created surface.
Regular movement slowly relaxes this finish. Gentle washing also makes the fabric more flexible. The silk underneath begins to move more freely.
As a result, Xiangyunsha becomes softer, smoother, and more comfortable over time. Its shine also becomes quieter and warmer. Natural folds and color changes create a personal patina.
This transformation is not simply wear and damage. It is part of the fabric’s character. Older Xiangyunsha can feel more supple than new cloth, as also documented in accounts collected by People.cn.
A Fabric That Records Time
Xiangyunsha is more than dyed silk. It carries the history of Guangdong, the knowledge of generations, and the marks of the natural world.
Its journey follows a strict order. Silk is prepared. Dioscorea color is built through Three Steams, Nine Boils, and Eighteen Sun-Dries. River mud creates the black face. Washing, evening moisture, stretching, and resting complete the cloth.
After that, the wearer continues the story. With every careful use, Xiangyunsha becomes softer and more personal. It is a fabric made by time—and improved by time.
