Abstract: The purpose of this research is to analyze the effects of Dansam and Sappan wood extract to perform
combination dyeing on silk fabrics, with respect to color changes, fastness (washing, dry cleaning, perspiration, rubbing and
light fastness), and functionality (antibacterial activity and deodorization). Combination dyeing was performed by first
combining Dansam with Sappan wood, then Sappan wood with Dansam, in these orders. Given the changes in the
combination ratio, pre-mordant treatment was performed. Looking at the surface colors of each dye, Dansam generally
produces YR color series, while Sappan wood produces YR, R, and RP color series. The effects of changing the order in
which combination dying was performed on the surface colors were as follows. First, combination dyeing (A) was performed
by using Dansam before Sappan wood, to produce YR and R color series. Then combination dyeing (B) was performed by
using Sappan wood before Dansam, to produce YR, R, and RP color series. By visual inspections, more similar color changes
of the combination dyeing were noticed with the post-dyeing material rather than the pre-dyeing material. Therefore, it was
presumably confirmed that surface color changes of combination dyeing were greatly influenced by the post-dyeing color.
Individual dyeing tests for fastness showed that Dansam was comparatively superior to Sappan wood, which demonstrated
lower fastness to washing, dry cleaning, perspiration, and light, relatively. The fastness of combination dyed samples was
shown middle, but similar fastness to the post-dye material, The fastness of (B) method was higher than (A) method in the
washing and light fastness. This confirms that color fastness from combination dyeing was considerably influenced by the
post-dye material. It was found that all dyed samples had a very high bacterial reduction rate of 99.9% and high
deodorization rate of 95%. |
