초록/해제: 요약 :The objectives of this study were to investigate the effects of mordants - on the dyeability and color fastness of the fabric. The natural yellow color used were extracts from Amur cork tree.The results were as follows: 1. The main color substances in extracts from Amur cork tree was expected to be berberine by spectrophotometric and HPLC studies. 2. The wavelengths of the strongest absorption bands of Amur cork tree extract was 420nm which was not changed after the mordants was added in the color extracts. The bands of Amur cork tree extract shifted to longer wave length side. And the abosorbancies were increased as pH of the extract increased. 3. As to the concentration of color extract for dyeing, about 10g/L was the optimum concentration to dye cotton fabric with extracts. 4. When cotton fabric dyeing with Amur cork tree extracts by using mordants, the K/S values of dyed fabrics were increased gradually as the concentration of mordants increased, and reached the highest values at the concentration of 5-10%. This indicated that K/S values were much influenced by dyeing method with mordant. 5. The color fastness of fabrics dyed with color extracts against dry cleaning, washing, rubbing and perspiration was improved 1 level by using mordants.
