Dyeing is the process used to fix color to a textile or plastic. While the color is contained in the dye or pigment, other chemicals are used to allow the material to absorb the dyes and bind them to the yarn. These include polymeric resin, binders, plasticizers, and surfactants.(1) Dyeing can be used to color yarns, fabrics, garments or to create prints. The dyes themselves can contain heavy metals and hazardous chemicals, which can break down into carcinogenic compounds and cause allergic reactions to workers and wearers.(2) With rising public awareness of environmental and health concerns, natural dyes that offer an alternative to harmful chemicals are increasing in both availability and popularity.(3)
