Pigment Dyeing
Dyeing with insoluble colored particles affixed to the surface of the fabric with a binder. Used on a variety of fibers, including cotton and synthetics.
Disperse Dyeing
This method uses non-water-soluble dyes that are finely ground and dispersed in water, typically for dyeing polyester and other synthetic fibers.
Tie-Dye
A method where textiles are tied in patterns and then dyed to create unique, multi-colored designs. Commonly used for T-shirts and fabric projects.
Vat Dyeing
Involves the insoluble dye being reduced in a vat to a soluble form, and the fabric is immersed in the vat. Used for cotton, wool, and other cellulosic fibers.
Batik
An Indonesian technique of wax-resist dyeing applied to whole cloth. Used primarily for cotton and silk fabrics.
Ikat Dyeing
A technique where threads are dyed before they are woven into textiles, creating complex patterns. Typically used for cotton, silk, and other traditional weaving fibers.
Direct Dyeing
A process where dyes are applied directly to the fabric without any fixing agent. Mostly used with cotton, paper, leather, wool, silk, and nylon.
Sulfur Dyeing
A low-cost dyeing method producing dark colors on cotton with dyes that are insoluble in water but have been reduced with sulfur or sodium sulfide.
Acid Dyeing
A technique using dyes that are set in acidic conditions, often providing bright colors on animal fibers and some synthetics, like nylon and silk.
Reactive Dyeing
A method where a dye forms a covalent bond with the fiber, resulting in high washfastness. Suitable for cotton, wool, silk, and nylon.
