| The natural dyestuff can differ in brightness, chroma, and color under several conditions. We intend to show the difference in color and chrominance of yellow dyestuff that is shown in Hanji fabric, according to mordant agents and mordant methods, using the statistics of Hunter`s value and Munsell`s value.
The results from these analyzes are as follows :
1. The effects of dyeing differ according to mordant methods. In the case of dyeweed, pre-mordant process was much more effective and in the case of curcuma and betel nut, the difference in color from the utilization of different mordant methods was not noticeable. Moreover, there was almost no change or effect from the use of aluminum mordant in the case of betel nut.
2. In order for effective dyeing, different mordant methods should be implemented according to different mordants. When dyeing with bud of pagoda tree, in the case of aluminum mordant, post-mordant process was effective and in the case of copper, iron mordant, pre mordant process was effective. When dyeing with rhubarb and polygonum cuspidatum, when using aluminum and copper mordant, pre-mordant process was effective.
3. Yellow color usually appeared at the use of aluminum mordant, and gardenia jasminoides, barberry root lead to reddish yellow, curcuma, Amur cork-tree, bud of pagoda tree to greenish yellow and dried clove bud, dyeweed to pure yellow.
4. Most of the yellow dyestuffs showed greenish grey at the use of iron mordant.
5. Amounts of dye uptake, K/S and the concentration of color showed little relevance. Rhubard, for instance, showed low dyeing volume while its dyeing color showed to be very dark and thick.
Therefore, in order for effective dyeing using the yellow natural dyestuffs, the use of an appropriate mordant and deciding on the correct mordant method is crucial. |
