Abstract

In this study, we used various dyes from natural pigments such as tumeric, goldthread, indigo, pagoda tree flower, sappanwood, and safflower to make the Hanji wallpaper with super eight colors of yellow, orange, green, turquoise, violet, red, blue, and magenta. As a result of measuring the lightfastness, magenta dyed with sappanwood showed the worst effect, but blue dyed with only indigo showed the best effect. In terms of the spot test by water, red wallpaper dyed with safflower showed the clear spot, but blue, turquoise, and green dyed with indigo resulted in a little spot. The orange, violet, and magenta dyed with goldthread and sappanwood showed antibacterial activity, and the turquoise, green, and blue also has a little antibacterial activity. However, yellow and red didn't show the some result as expected. In the experiment for efficiency of formaldehyde removal, all Hanji wallpapers dyed with natural pigments showed the significant removal effect of formaldehyde, especially turquoise and red were the highest.
