― In order to examine the availability of a heating process for p ersimmon dyeing, the cotton fabrics treated with various concentrations of persimmon extracts were heated at var ious temperatures and times. The raw and fermented persimmon extracts were used for the coloration. For both extra cts, the color strength of fabrics was increased with the increase of coloration temperature, time, and concentration of the extracts. Considering the practical aspects and color strength, the temperature around 200℃ and the time longer than 60 minutes can be determined as the op timum coloration conditions of persimmon extracts onto cotton fabrics. However, somewhat loss of strength by the heating process seems to be inevitable. The color fastness to washing was excellent for both color change and staining showing a rating of 5. |
