Claims10
A natural dyeing method using fermented persimmon juice, the method comprising:
- a first process of preparing fermented persimmon juice;
- a second process of adding a fabric and the fermented persimmon juice to a sealed container and hermetically storing the fabric and the juice at a temperature between about 20° C. and about 30° C. for about 6 hours to about 10 hours;
- a third process of performing a dying process by immersing the fabric taken out of the sealed container in the fermented persimmon juice and drying the immersed fabric;
- a fourth process of uniformly spraying water onto both surfaces of the fabric subjected to the dyeing process to perform a color development process by oxidative polymerization;
- a fifth process of performing a post-treatment process by immersing the fabric subjected to the color development process by oxidative polymerization in water for about 18 hours to about 30 hours and drying the immersed fabric;
- and
- a sixth process of coating both surfaces of the fabric subjected to the post-treatment process with a silicon coating solution to produce a naturally dyed fabric.
