Color measurements of dyed fabrics
The results of color measurements of the dyed silks are
shown in Table 6.
K/S value of the unmordanted dyed sample was found
to be 11.85. This dye uptake on the silk fiber is attributed
to the structural features of the fiber. However, in the
mordanting method, mordant resulted in improved color
yield of the dyed fabrics, except tin. Ferrous sulfate as a
mordant significantly increased the color yield of silk. The
K/S value was found to be 17.46 using ferrous sulfate
which showed the maximum relative surface color strength
value of 147.4 % considering the unmordanted dyed sample
as reference. Besides, using alum with ferrous sulfate, and
tin and alum with ferrous sulfate as a combination, color
strengths were found to be 140.3 % (K/S = 16.62) and
121.7 % (K/S = 14.42), respectively.
In single mordanting process of silk, the order of color
yield was found to be ferrous sulfate > alum > tin. It was
obvious that color yield gradually decreased when
approached from ferrous sulfate to tin. Again, among the
four different combinations of mordants, the order was
