ABSTRACT

The objective was to investigate the efficacy of Metasequoia(Metasequoia glyptostroboides) cone colorants as a new functional dye for wool fiber. Effects of dyeing conditions and mordanting on dye uptake, color change, and colorfastness were investigated for wool fiber. Compared with cotton and silk fibers, wool fiber showed better affinity for the Metasequoia cone colorants. Fe and Cu mordants improved dye uptake, and mordanting did not change the color of dyed fabric with YR Munsell color. Colorfastness to rubbing and washing was as good as grade 4, whereas lightfastness of the dyed fabrics was above grade 3. Antimicrobial activity of the colorants was very high 99.3% of reduction rate toward S. aureus. It was confirmed that Metasequoia cone colorants can be utilized as a new functional natural dye for wool fiber. In addition, considering its high antimicrobial functionality it could be applied to cosmetics and food.
