In order to examine the availability of a heating process for persimmon dyeing, the cotton fabrics treated with various concentrations of persimmon extracts were heated at various temperatures and times. The raw and fermented persimmon extracts were used for the coloration. For both extracts, 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 $200^{curc}C$ and the time longer than 60 minutes can be determined as the. optimum coloration conditions of persimmon extracts onto cotton fabrics. However, somewhat loss of strength by the hearing process seems to be inevitable. The color fastness to washing was excellent for both color change and staining showing a rating of 5.
