  • In this study, Water Repellent Finish was carried out before dyeing on cotton fabrics. It was aimed to improve on dyeing properties of cotton fabrics with direct dye. The results obtained were summerized as follows: 1. The K/S value of water repellent finished cotton fabrics increased. This phenomena in water repellent finished cotton fabrics were much more noticiable than unfinished cotton fabrics. 2. The color fastness(light, washing, and rubbing) of water repellent finished cotton-dyed were worse than those of unfinished cotton-dyed with direct dye. △E of water repellent finished cotton fabrics wasn't showed significant difference as compared with that of unfinished cotton fabrics. 3. The water repellency of finished cotton after dyeing got down from 100 to 70. That of finished-cotton before dyeing was 100. 4. Moisture regain, stiffness and weight of finished cotton fabrics were not almost differenciated with unfinished cotton fabrics. Moreover, the tensile strength of finished cotton fabrics was increased compared to that of unfinished cotton fabrics. As conclusion, according to the above results when the cotton fabrics were dyed with direct dye, it was much more effective that water repellent finished cotton fabrics were dyed rather than trational process, that is pre-dyeing after-finishing even if, by low liquor ratio. The physical properties of fabrics were maintained or increased.

  • The cotton leafroll dwarf virus (CLRDV) is one of the most devastating pathogens of cotton. This malady, known as cotton blue disease, is widespread in South America where it causes huge crop losses. Recently the disease has been reported from India. We noticed occurrence of cotton blue disease and chickpea stunt disease in adjoining cotton and chickpea fields and got interested in knowing if these two viral diseases have some association. By genetic studies, we have shown here that CLRDV is very close to chickpea stunt disease associated virus (CpSDaV). We were successful in transmitting the CLRDV from cotton to chickpea. Our studies indicate that CpSDaV and CLRDV in India are possibly two different strains of the same virus. These findings would be helpful in managing these serious diseases by altering the cropping patterns.

  • 본 연구는 우리나라에서 거의 소멸된 면화재배의 지역적인 축소 과정을 확인하고, 현재 농촌에서 이루어지는 면화재배의 의미를 파악하였다. 해방 이후 우리나라의 면방직 공 업은 원면도입으로 해외 원료 의존형 산업이 되었다. 환율정책으로 국내면 가격이 미국산 원조면보다 비싸지고, 정부의 식량증산 위주의 농업정책, 유통구조 등으로 인해 국내면의 재 배면적이 감소되기 시작하였다. 국내 면 재배 면적 감소의 지역적인 과정은 일차적으로 기 후조건이 면화재배에 불리한 지역에서 먼저 나타나 식량 밭작물로 대체되었고, 이후 재배 유인력이 더욱 약해짐에 따라 재배 발원지를 제외한 다른 지역에서는 거의 소멸되고 있었 다. 현재 농촌에서 면화는 이불솜 을 위한 자가 소비용, 식용, 약용외에 다른 작물의 생산성 을 높이기 위한 부작물로서 재배되고 있음이 확인되었다. 재배방법은 종래와 큰 차이가 없 이 행해지고 있었으며 노동집약적으로 생산되고 있다. 농민의 면화에 대한 애착이 강하고, 국내면으로 만든 이불솜을 선호하는 소비자들의 수요가 아직 있음이 확인되어, 정부의 정책 적인 배려와 함께 시장이 확보될 경우 국내면이 앞으로도 재배될 수 있는 가능성을 보여주 고 있었다.

  • Cotton, rayon/cotton, and Tencel twill weave fabrics were used to investigate the effect of fiber types on the cellulase washing finish. And twill. basket, and derivative weave cotton fabrics were used to study the weave effect. Various fabrics were treated with neutral cellulase varying treatment times and with acid cellulase, stone, and stone-neutral cellulase respectively for two hours in a rotary washer. Weight loss decreased in the order of rayon/cotton> cotton> Tencel, and basket and derivative weave fabrics lost more weight than twill weave fabric. Color difference decreased in the order of cotton> Tencel> rayon/cotton, and twill weave fabric had larger color difference than derivative and basket weave fabrics. Back staining decreased in the order of cotton> rayon/cotton> Tencel, and twill weave fabric had larger back staining than derivative and basket weave fabrics. Tear strength retention decreased in the order of rayon/cotton> cotton> Tencet and twill weave fabric had larger tear strength retention than derivative and basket weave fabrics. Flex stiffness retention decreased in the order of cotton> Tencel> rayon/cotton, and in the order of derivative> twill> basket weave. In cotton fibers, damage of primary wall was observed. And the cellulase treatment on Tencel seemed to roughen the fabric surface slightly, and to fibril fibers along the fiber axis.

  • Safflower red and Amur Cork Tree dyes have used for dyeing on cotton fabrics largely. But they have low degree of lightfastness, So this study investigated the effect of BTCA pre-treatment on lightfastness of cotton fabrics dyed with Safflower red and Amur Cork Tree. The result is as the following; By FT-IR spectra, crosslingking was proved in cotton fabric pre treated with BTCA. K/S value of Safflower red dyed cotton fabric pretreated with BTCA was much more decreased than untreated cotton fabric with BTCA. It showed that the hue of the Safflower red dyed cotton fabric changed from reddish purple to red. However, K/S value of Amur Cork Tree dyed cotton fabric pre treated with BTCA was much more increased than untreated cotton fabric with BTCA. It showed that the hue of the Amur Cork Tree dyed cotton fabric changed from green yellow to yellow. For K/S value of Combination dyed cotton fabric pre treated with BTCA, Safflower red color was much more decreased than untreated cotton fabric. But Amur Cork Tree color was much more increased than untreated cotton fabric. It changed from reddish purple, red, yellowe red, to yellow in hue. ${{\Delta}E^*}_{ab}$ of Combination dyed cotton fabric in 40 hours irradiation was 15.7, however ${{\Delta}E^*}_{ab}$ of Combination dyed cotton fabric treated with 2% BTCA was 8.0, and that treated with 3% BTCA was 9.8. So, pre-treatment with BTCA to combination dyed cotton fabric with Safflower red and Amur Cork Tree showed more effective improvement of Lightfastness than untreated cotton fabric with BTCA.

  • This study evaluate the effect of laundering on the deformation of knitted spandex/cotton fabrics compared with that of knitted cotton fabrics. Commercial knitted spandex/cotton and knitted cotton fabrics for T-shits were laundered in a drum-type washing machine and dried in a tumble dryer. Wale spirality, shrinkage, elastic recovery and surface contour of knitted fabrics were investigated under different laundering conditions: washing temperature, presoaking time and washing cycles. Knitted spandex/cotton fabrics had a lower angle of spirality than knitted cotton fabrics. After the first washing cycle, the angles of spirality of all the fabrics had decreased greatly. Knitted cotton fabric of low density deformed more than that of higher density. Knitted spandex/cotton. fabric of low density shrank less, because of the greater extension given during heat-set. Permanent elongation length at the 80$\%$ extension was longer than at the 50$\%$ extension, and the knitted spandex/cotton fabric which was expanded greatly during heat-set had a lower elastic recovery rate. The surface appearance of the knitted spandex/cotton fabrics was worsl~ than that of the knitted cotton fabrics before laundering and after repeated laundering, because of the much protruded cotton fibers from the yarns.

  • 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.

  • Archaeological evidence shows that cotton fibres of the genus Gossypium were first used for textile production at Mehrgarh, Pakistan in the Neolithic period ($6^{th}$ millenium BC). Eventually the cotton plant and textiles found their way to Egypt and through there, to Greece. However, the chronological origins of the cultivation and/or use of cotton fibres in textile production in ancient Greece are ambiguous. The main sources of information are ancient written texts and excavated textile finds. Both indicate that the introduction of cotton in Greece can be placed in the mid-first millenium BC. However, it is not clear whether the cultivation of the plant and consequently the production of cotton textiles was established in that period or whether another cotton species was produced and used locally in Greece or whether isolated examples of cotton textiles had been imported in Greece before the cotton plant. A more comprehensive analytical study of surviving textile finds coupled with archaeological research for plant production and cultivation would provide the answer to these questions.
