This study investigated the dyeability and color change of the natural dyes of SeaCell, a biodegradable functional fiber that is permanently added to cellulose fibers with natural additives extracted from seaweeds. The natural dyes used in the study are five dyes. Gardenia and turmeric, which are yellow-based natural dyes, Sappan wood and Lac, which are red-based natural dyes, and Indigo, a blue-based natural dye, were selected. The dyeability and color change according to the change of the mordant conditions and the number of times of dyeing were investigated. In addition, the dyeing properties and colors of cotton and silk fibers were compared under the same dyeing conditions as SeaCell. The study results are as follows. It was found that SeaCell had lower dyeing properties than silk, a protein fiber, in gardenia, sappan wood, and lac dyes, but had higher dyeing properties than cotton with the same cellulose component as SeaCell fibers. In the case of turmeric, it showed higher dyeing properties than cotton except for the no mordant condition. In the case of Indigo dye, SeaCell shows the best dyeability, indicating that it is a very suitable fiber for Indigo dyeing. As sustainable functional fibers are continuously developed in the future, natural dyes that are environmentally friendly and human-friendly are actively introduced and commercialized, and it is expected that they can be used as reference materials.
