Sun dye, also known as solar dyeing or sun printing (when used with cyanotype), is a method of dyeing fabrics and paper using sunlight as the primary agent. It's a unique photographic printing process where dyes, often applied before the sun exposure, react to UV light to develop their color and create a permanent image. The process often involves placing objects on the fabric or paper before sun exposure to create patterns or stencils, preventing dye from reaching the fabric beneath.
Types of Sun Dyes & Processes
Several types of dyes are employed in this process:
-
SolarFast dyes: These dyes only develop color and become permanent after exposure to sunlight (UV). They allow for interesting effects and precise control over the final image due to their sensitivity to UV light.
-
Sun Dyes (heliographic or sun-sensitive fabric paints): These are specially formulated paints that react similarly to SolarFast dyes, becoming permanent only after UV light exposure. They allow for more paint-like application and sharper lines.
-
Natural dyes: Natural materials, such as plants and flowers, can also be used in solar dyeing. The process is similar; however, the results are often softer and less vibrant than the use of commercial sun dyes. The sun's heat slowly dyes the fiber.
How Sun Dyeing Works
- Application: The chosen dye is applied to the fabric or paper.
- Object Placement (optional): Objects like leaves, flowers, or stencils can be placed on the dyed surface to create patterns. These act as resist, blocking the light and preventing dye development in those areas.
- Sun Exposure: The dyed fabric or paper is left in direct sunlight for a period of time. The exact duration depends on the dye, intensity of the sun, and desired color depth.
- Color Development: UV light in sunlight initiates a chemical reaction in the dye, causing it to develop its color and become permanent.
- Rinsing (Usually): After sufficient sun exposure, the fabric or paper is rinsed to remove any excess dye and set the color.
Practical Applications and Examples
- Fabric dyeing: Create unique designs on clothing, tote bags, or other textile items.
- Paper crafting: Produce artistic prints on paper for cards, scrapbooking, or other crafts.
- Yarn dyeing: Add unique colors and patterns to yarn for knitting or crocheting projects.
Examples of specific sun dyeing processes include:
- Sun printing with leaves and flowers, creating natural imprints on fabrics.
- Using stencils or found objects to create a range of designs.
- Utilizing different types of sun dyes for varying levels of color vibrancy and detail.
