Dyes are soluble colorants that attach in molecular form to fibers.

Optical Brighteners are fluorescent dyes used to make white textiles appear brighter.

Reactive Dyes forma chemical bond with a fabrics fiber, giving the fabric bright color and improved lightfastness abd washfastness.

Discharge removes dye from fabric in printing, typically so that another color can be applied.

Crocking means that the color from the dye or pigment is being rubbed off or "transferred" from the fabric onto another surface or portion of the same fabric.

Enzyme washing is a process that gives dyed fabrics a worn or aged appearance.

Lightfastness indicates how resistant a dye is to fading when exposed to light.

Padding is a method of dyeing that uses only enough strong dye solution to saturate the fabric.

Pigment Dyeing uses insoluble pigments mixed with a binder to color a fabric, typically producing a softer, aged appearance.

Washfastness indicates the ability of a dye to resist washing out of the fabrics fiber.
