축합형 감 탄닌 추출물의 열 발색공정에 의한 면직물 염색

The heating process for coloration of persimmon extracts was examined instead of the general light irradiation method. The raw and fermented persimmon extracts were investigated in terms of the coloration phenomena onto cotton fabrics at various conditions. For both extracts, the color strength of fabrics was increased with the increase of coloration temperature, time and concentration of the extracts. The color fastness to washing was excellent for both color change and staining showing a rating of 5.
