Abstract
The Gal-ot, a garment made of cotton fabrics dyed with the fruit juice extracted from immature persimmon, had been widely used in Jeju Island, Korea.
Persimmon fruit tannin, when used as a dye, is known to strengthen the cotton fabrics and to help maintain the garment sanitarily sound because it keeps molds from growing.
Although Gal-ot has recently been replaced by synthetic fabrics for economic reasons, its value has been reevaluated lately for its natural beauty; the increasing sentiment to restore something traditional, beautifully-colored, and natural has added to this reevaluation.
In the present study, we investigated the dyeing potential of immature fruit juice with special emphasis on color emergence of cotton fabrics, dependent on cultivars and developmental stage of the fruits.
Fruits of five local varieties in Jeju Island and three commercial cultivars of Japanese origin were collected from late June to late August at 10-day intervals.
Results indicated that the less mature the fruits the higher the soluble tannin concentrations, and the more tannin the darker the cotton fabrics.
Fruits of local varieties contained more tannin than those of commercial cultivars.
