Pigment dyes work by adhering colored particles (pigments) to fabric fibers using a bonding agent. Unlike dye-stuff which penetrates the fibers, pigments sit on the surface.
The Pigment Dyeing Process: A Step-by-Step Look
-
Fabric Preparation: The garment is typically cut and sewn before dyeing. This is a key difference from traditional dyeing methods.
-
Pigment Application: The pigment, a finely powdered color, is mixed with a binding agent (a chemical that helps it stick to the fabric).
-
Adhesion: The pigment mixture is then applied to the fabric. The binding agent ensures that the pigments adhere to the fabric's surface. This is crucial; without it, the pigment would wash away.
-
Curing: The garment undergoes a curing process, often involving heat, to set the pigment and binding agent, making the color fast and durable.
-
Finishing: After curing, the garment may undergo additional finishing processes to improve its softness, hand-feel, and overall quality.
Advantages of Pigment Dyeing:
- Softness and Drape: Pigment-dyed apparel is often praised for its soft feel and excellent drape.
- Vibrant Colors: Pigments can produce very bold, vivid colors.
- Versatility: The process works with various fabrics and garment constructions, making it versatile.
Example:
Imagine a t-shirt. In pigment dyeing, the t-shirt is cut and sewn first. Then, the pigment and binding agent are applied, cured, and the finished product is a vibrant, soft, pigment-dyed t-shirt.
Note: As indicated in the provided reference, pigment dyeing typically happens after the garment is constructed. The bonding agent is essential for the process to be effective.
