In this study, a change of hand of fabrics dyed with persimmon juice was measured using Kawabata Evaluation System. Using various cotton fabrics, linen fabric and silk fabric used frequently for persimmon juice dyeing, we examined the changes of physical properties and hand according to persimmon juice dyeing and washing. The dynamic characteristics of hand were measured tensile, shear, bending, compression, surface properties, thickness and weight. Linearity of load-extention and tensile resilience were increased in all kinds of fabrics after dyeing. Tensile energy decreased in cotton fabric 2(gauze), cotton fabric 3(muslin) and linen fabric. Shear stiffness and hysteresis of shear increased in most of fabrics. Bending rigidity of the bending property and hysteresis of bending, linearity of compression of the compression property, compression energy and compression resilience increased in all kinds of fabrics after dyeing. Thickness and weight increased much in all kinds of fabrics after dyeing. In the primary hand value, stiffness and anti-drape stiffness increased in all kind of fabrics after dyeing. The fullness and softness, crispness, scrooping feeling and flexibility with soft feeling decreased. As the stiffness after persimmons dyeing increased, it was suitable for clothes material of summer.

Dyeing and discoloration effects on the fabrics of cotton, silk and rayon with unriped persimmon juice were investigated. Color of dyed fabrics treated with persimmon juice only, added 3% tartaric acid or 3% aluminium sulfate was not different each other. Dyeing assistants such as tartaric acid or aluminium sulfate were effective on the prevention from discoloration of dyed fabrics and ultraviolet rays. Discoloration were supposed to derive from tannin in unriped persimmon, ultraviolet rays, oxygen, enzyme and so on, ultraviolet rays at wavelength of 253.7nm was the most active the chromatophores and discoloration. The fabrics could be dyed, when unriped persimmon juice was store at low temperature or freezing.

제주도민이 오랫동안 주로 노동복으로 착용해 온 갈옷의 이용 범위를 확대시키기 위하여 현대 감각에 맞는 갈옷의 일상복과 외출복을 고안하여 제작하였다. 또한 감물 염색으로 퇴색된 옷을 재활용하는 방법, 염색방법의 고찰, 감즙 염색에 있어서 재질의 적합성과 다양성 등을 살펴보았다 그 결과 재활용 아동복과 소창을 이용한 개량한복에의 응용은 갈옷 이용 범위의 확대를 시사하였다. 앞으로 갈옷의 단점을 보완할 수 있는 염색법의 간소화와 후처리법의 개발에 연구의 중점을 두면서 갈옷의 장점을 이용하여 용도에 알맞은 디자인을 계속해서 연구, 개발한다면 우리 전통 의상인 갈옷을, 시대에 어울리는 실용적인 의상으로 발전시킬 수 있을 것이다.

Three pieces of cotton fabrics used for this study were exhumed in the Mt.Moo Deung near Kwang Ju in 1965. The fabrics were remains of Jang Heung Lim Si-the nephew's wife of General Kim Deok Ryeong. It was reported that Jang Heung Lim Si died in 1615. The cotton fabrics were classified into three, A, B and C, according to their color. The fabric A was inherent color of cotton, the fabric B was that of light brown and the fabric C was that of dark brown. The physical and chemical characteristics of the cotton fabrics were examined. In the meantime the construction of cotton fabrics and traditional dyeing of Yi dynasty were studied through various records. The results were as follows: 1. According to electromicroscopic examination, the lumen in the cotton fiber had not been developed enough, therefore the quality of cotton at that time was supposed to be not so excellent. 2. The results of chemical analysis indicated that: (1) While the copper number of the cotton fabric A was similar to that of bleached cotton, that of the fabric C was extremely high. (2) The amount of methylene blue absorption was much more than that of normal cotton. (3) The content of cellulose was less than that of normal cotton. (4) The degree of polymerization was less than that of normal cotton. From the results mentioned above, it was concluded that the cotton fabrics were oxidized slowly in the closed lime coffin for a long period of time. From this process of oxidization and deterioration, the degree of polymerization was decreased through depolymerization, and carboxyl groups were produced by the oxidization at reducing end groups. 3. It was confirmed that the cotton fabric C was dyed by the juice of immature persimmon. Thus, it was inferred that the large amount of copper number of cotton fabric C was derived from phenolic OH groups of tannins having high reducing properties in persimmon.
