A Study on Dyeing Effects of Onion′s Outer Shell under the Different Dyeing Conditions
염색조건에 따른 양파껍질의 염색효과에 관한 연구
Abstract
The purpose of this study was to identify the best dyeing conditions using onion's outer shell. and to apply to the method in practical daily life. To do this. we extracted quercetin from onion's outer shell and dyed several natural fabrics such as cotton, slack mercerized cotton, ramie. and silk. under the different conditions. Dyed fabrics were Investigated in the aspect of dyeability and colorfastness. The effective conditions for the light-fastness and washing-fastness also have been studied. The results of the experiment were varied with such conditions as temperature. time. pH degree. and treatment and types of mordants. The results are as follows ; 1. Fabrics dyed with onion's outer shell showed excellent dyeability even though there were no mordants, and the silk fabric dyed better than both cotton and ramie fabric. Furthermore, in the cases of repeated dyeing and treatment of mordants using AIK(SO
