A natural dyeing method using shouliang yam rhizome, the method comprising:
- a first process of preparing a shouliang yam rhizome extract by mixing crushed shouliang yam rhizome and water, and then extracting the mixture at a temperature between about 28° C. and about 36° C. for about 1 hour to about 5 hours;
- a second process of performing dyeing twice or more by immersing a fabric in the shouliang yam rhizome extract and drying the immersed fabric;
- a third process of performing first color development twice or more by immersing the fabric subjected to the dyeing process in a mixed solution of the shouliang yam rhizome extract and water and drying the immersed fabric;
- a fourth process of performing aging twice or more by uniformly spreading mud on one surface of the fabric subjected to the first color development, followed by aging for about 60 minutes to about 90 minutes, and drying the aged fabric;
- a fifth process of performing second color development twice or more by immersing the fabric subjected to the aging process in the shouliang yam rhizome extract and drying the fabric;
- and
- a sixth process of coating both surfaces of the fabric subjected to the second color development process with a silicon coating solution to produce a naturally dyed fabric.
