Dyeinkt

Dyeinkt is a term used in the field of ink chemistry and textile printing to denote a class of dye-based ink formulations designed to transfer soluble or dispersed dyes into fibers or substrates. The name is a blend of dye and ink, reflecting its function as an ink carrying dye molecules rather than pigment particulates.

Chemistry and operation: Dyeinkt formulations typically rely on water- or solvent-based carriers that solubilize or suspend dye molecules. They may include binders, surfactants, and leveling agents to improve adhesion and print quality. In textile printing, heat or chemical fixation is used to bind dyes to fiber, resulting in colorfastness.

Applications: In digital textile printing, dyeinkt inks are used in inkjet printers to produce vibrant, continuous-tone images on natural and synthetic fibers. They are also used in art and photographic printing on specialty papers, where high color range is desired.

Advantages and limitations: The main advantages are bright colors, broad gamut, and potential for lower environmental impact if water-based. Limitations include variable wash and lightfastness depending on fiber and dye class, potential migration or bleeding on certain substrates, and compatibility requirements with printers and curing processes.

Status and research: Dyeinkt is not a standardized category; it is used by manufacturers to market dye-based inks. Research focuses on improving dye fastness, expanding fiber compatibility, and reducing formulation costs. Standards bodies occasionally publish performance metrics for print permanence and safety.
