Dyeing of Sphagnum Moss for the Flower Design with the Extract of Marigold

This study was conducted to clarify the effects of dyeing conditions on the dyeability of the discolored sphagnum moss which was dyed with 1% extract of marigold at 100℃ for sixty minutes. The hue of dyed sphagnum moss was generally shown an Y and YR levels. In the higher concentration of extracting solution, E values of sphagnum moss was increased, however, those V and L* values were decreased. Regardless of dyeing temperatures, colors of sphagnum moss non-mordanted and dyed was YR level, those treated AIK, NaOH and Fe with mordants were all Y level. And E values was significantly increased in the higher dyeing temperatures. In the longer dyeing times, V and L* and b* values were decreased, and E values was increased. However, those H, C and a* values were not significant among treatments. In general, dyeability of sphagnum moss dyed with the different pH ranges had not a uncertain tendency.
