  • In order to examine the availability of color developing for prepared persimmon extract powder dyes, purified and freeze-dried powder from immature persimmon fruit. The cotton fabrics dyed with 1% concentration of powder dyes. This study was conducted to examine into the color developing effects of the powder dye for the dyed cotton fabrics irradiated with xenon light. Powder dye is difficult to dissolve in water resulting in a colloidal and viscous solution. The problem of solubility in water was resolved by setting the dyeing conditions by wetting the dye with alcohol in advance and dissolving in warm water($50{\sim}60^{\circ}C$). Samples had no alkaline conversion in making process of powder dyes showed high color developing effect(${\Delta}E^*$, K/S). Samples showed decreased ${\Delta}E^*$, K/S with increased alkaline conversion in making process of powder dyes. Samples that had alkaline effects displayed easy early color developing to be advantageous in the process of natural pattern in art work.

  • This study aims to provide practical information of both color and hands of cotton fabrics dyed with persimmon dye powder for natural dyeing fashion industries by investigating dyeing behavior and color gamut, by testing mechanical properties depending on color characteristics, and finally by evaluating dyeing fastness. As results, the persimmon dye powder obtained by extracting the fruits to final solid powder was found as containing tannin and it partially coated between and on fibers similarly to traditionally dyed one. The K/S values of non-mordanted fabric and two differently mordanted ones with Fe and Cu seemed to reach their equilibrium from 800, 800, and 600% (owf), respectively. Yellow-red was the only one hue shown while tones were various as pale (p), light grayish (ltg), soft (sf), dull (d), grayish (g), and dark grayish (dkg). In mechanical properties, the dyed fabrics with p and ltg tended to be less altered than undyed ones whereas d and d kg by higher bath concentrations could be applied to boxy silhouette owing to their increased stiffness and less stretchability. Although fastness to dry cleaning and stain was good, color change by washing and rubbing needed to be improved.
