  • The cotton, wool, cotton/wool blended(80:20) and tencel fabrics were treated with low temperature oxygen or argon plasma, enzymes(cellulase or protease), or oxygen plasma-enzyme and examined for their weight loss and conditions for treatment for the environment friendly finishing. In the plasma treatment argon gas had better effect on the weight loss than oxygen gas did and the weight loss of all the fabrics was increased as increasing discharge power and discharge time. The weight loss of cotton, wool, cotton/wool blended(80:20) fabrics decreased in a large measure after 1 hr but that of tencel didn't decrease after 1 hr. In case of cellulose fibers oxygen gas plasma induced chemical functional groups on the surface of substrate more than argon gas plasma did so the weight loss of wool was larger than that of cotton, tencel fabrics in oxygen plasma-enzyme treatment. The weight loss of cotton and tencel fabrics decreased the initial stage because oxygen plasma pre-treatment caused cross linking as well as etching effect but argon plasma pre-treatment didn't. The plasma pre-treatment cleared the way for enzyme treatment on the whole but oxygen plasma pre-treatment bear in hand the increase of weight loss more or less because of the cross linking on the surface of cellulose fibers. The appropriate conditions for plasma treatment was 10-1Torr, 40W for 30minutes and for cellulase treatment were enzyme concentration of $3g/{\ell}$, pH 5, $60^{\circ}C$ for 1hr and for protease treatment were enzyme concentration of $4g/{\ell}$ pH 8, $60^{\circ}C$ for 1hr.

  • The purpose of this study is to dye hanji/cotton fabrics using persimmon juice and to investigate the change in the hand fabrics. Using the Kawabata Evaluation System, we have examined the changes in the physical properties, primary hand value and total hand value. The dynamic characteristics of hanji/cotton fabrics have been explored by tensile, shear, bending, compression, surface properties, thickness and weight. As a result, it can be seen that the linearity of load-extension and tensile resilience are increased with the increase of the concentration and dyeing times of persimmon juice and tensile energy is decreased in the same condition. These behaviors are shown in the compression properties. Although the mechanism of persimmon juice dyeing has been widely discussed, it means that the fabrics dyed with persimmon juice become stiffened and the elasticity is increased with the introduction of persimmon on the fabrics studied. Bending rigidity and hysteresis of the bending moment are increased with the increase of the concentration and dyeing times of persimmon juice. Also, Geometrical roughness, expressed in SMD is increased with increasing the concentration and dyeing times of persimmon juice, compared with as-received. It indicates that these results are due to the geometric structure of hanji yarn and the introduction of persimmon juice on the fabrics studied. The fullness and softness with the soft feeing are increased a little due to the tannin component of persimmon juice introduced on the fiber surface.

  • This study aims to seek knitting methods that can enhance the neck design of seamless knitwear and to find out how to improve the designs by comparing and analyzing the characteristics of the knitting methods used for v-neck pullovers. The investigator analyzed the characteristics of the knitting methods and assessed the wearing sensation by using six different pieces of clothing for the experiment. The results were analyzed based on a variance analysis (ANOVA). Among the items showing significant results, the Duncan-test was used for more intensive research. As a result, while using the basic pattern of knitting methods, Experiment Clothes A ended up binding on the back neckline, and not making the hem of back. Also, the neck was the widest. In the case of the special neck, Experimental Clothes B (1:1), which had the least number of the knitting course in relation to the knitting ratio, the bottom part of the back body had the most wrinkles. According to the result of wearing sensation, the front part, the side part, and the back part showed similar results (p<0.000) in all items. Specifically, the appearance of the Experiment Clothes A (normal) in both the front and rear aspects were evaluated as the best. In the case of the special neck, the Experimental Clothes F was ranked the highest, whereas the Experimental Clothes B (1:1) was ranked the lowest. Based on the results of the study, it seems possible to provide concrete and technical data for the planning of unique and productive designs. With regard to seamless knitwear neck designs, a comparative analysis of the knitting method of v-neck pullovers will be of practical use in the development and manufacturing of the product.

  • This study aimed to systematize the apparel vendor work processes and provide useful information to future employees of clothing export units by analyzing the processes of vendors' manufacturing tasks. A survey of 20 apparel vendors servicing mainly U.S. buyers was conducted on employees of overseas business departments working for more than five years. buyers. Based on the results, vendors mainly manufactured cut-and-sew knit products. Regarding the production method, OEM was used more frequently than ODM. Fourteen (70%) companies used the ODM method. This suggests that vendors are expanding their production method from OEM to ODM. In order to summarize the work of each business based on the clothing production process research results, buyers were in charge of planning products and the vendors were in charge of sampling. Production of materials and the approval of material tests were out sourced. Overseas factories of vendors were in charge of bulk (mass) production and garment finishing, as well as packaging and shipping the completed products. Even though the vendors' head offices do not directly produce clothes, they play a pivotal role in ensuring planning and management progress in clothing production. As buyers prefer direct contracts for cost reduction, the vendor additionally performs the role of an agent. Also, with the increase in ODM production ratio, the work area of the vendor is expanding. If Korean clothing exporters improve their global competitiveness by investing in the R&D of materials and design to enhance the ODM method, the development of Korea's clothing and export industry will benefit significantly.

  • The purpose of this study is to analyze the granny look of the new-tro trend via Alessandro Michele's Gucci collection and to provide a reference standard for future design developments by identifying the representation of the granny look. To analyze the new-tro trend and the granny look, basic concepts were analyzed through aesthetic and art books and the photographic data were collected through Internet sites. A total of 186 fashion images were considered as granny look by five clothing experts. The images were subdivided into silhouettes and items, materials, patterns, and colors to analyze the modeling factors and identify the intrinsic inner meaning based on the theory of Nostalgia. The analysis showed that the silhouette was expressed naturally without exaggeration or shrinkage. The thermosetting materials included fur, velvet, knit and quilted materials, while the colors showed raw and faded shades based on the use of natural colors. The patterns were mostly natural, such as flowers, leaves, and stalks, which were aimed at nature. The inner meaning of the granny look is based on the theory of Nostalgia, primarily because it is an emotional fairy tale and second, it reflected the sessions of nature. Also, it is a reinterpretation of the narrative. In conclusion, the academic and fashion industries need to understand the various emerging trends in accordance with the social and cultural backgrounds to derive a positive benefit.

  • The purpose of this study was to analyze the effect of fiber contents of socks fabric on the subjective sensitivity and emotional sensibility of consumers. We investigated the relationship of subjective sensitivity and sensibility according to fiber contents and color value of socks. We made five plain knit fabrics as specimens, with a combination of chitosan/SUS fiber contents and three value levels of grayish color. The subjects were 15 males and 54 females in the twenties. The data analysis was conducted with Pearson's correlation analysis, ANOVA, Duncan multiple range test, and regression analysis. The major finds were as follows: A factor analysis showed that subjective sensitivity was classified into five factors (bulky, surface-rough, elastic, attention, and variety) and emotional sensibility was into four factors (salience, stability, luxury, and activity). There were significant correlation between the subjective sensitivity and emotional sensibility. The subjective sensitivities of 'surface-rough' and 'elastic' were significantly influenced by fiber contents. The sensibilities of 'salience' and 'luxury' were significantly influenced by fiber contents. Where as the 'salience' and 'roughness' were significant influenced by color value level. According to sex, there were significantly difference in 'bulky', 'elastic' and 'salience'. As a result of the regression analysis, preference, consuming desire and satisfaction appears to be closely related with all subjective sensitivity and sensibility.

  • 섬유산업은 그 제조 스트림이 높은 오염 부하와 에너지 다소비를 특징으로 하여 환경규제에 따라 기존 시장의 위축 가능성이 상존하고 있다. 특히 섬유산업의 주요 스트림 중의 하나인 염색가공 공정은 섬유에서 불순물을 제거하고 심미한 색상과 사용 목적에 적합한 성능을 부여하는 단계로 섬유제조 공정에서 가장 높은 부가가치를 부여하는 단계이나 고온의 물과 다양한 화공약품을 많이 사용하고 그 처리온도가 비교적 높아($100^{\circ}C$ 이상) 대표적인 폐수 발생 공정이자 에너지 다소비 공정이다. 섬유의 염색 방법 중 반연속방법인 CPB(Cold Pad Batch)염색은 반응성 염료와 알칼리의 혼합액으로 구성된 염액에 원단을 패딩한 후 상온에서 수 시간 배칭하고 수세 및 후처리하여 염색하는 방법으로 작업공정관리, 설비관리가 간편하고 에너지소비량 절감, 높은 생산성의 장점이 있다. CPB염색법은 주로 직물에 적용되어 보편화 되었으며, 작업공정 중 장력의 영향을 많이 받는 니트 소재에 적용되는 사례는 드물다. 직물류의 CPB 염색가공법은 대구 경북을 중심으로 연구진행이 활발히 이루어지고 있어 국내 100대 정도의 CPB 관련 장비가 직물제품에 한정되어 가동되고 있는 반면, 니트 CPB 관련 염색 가공 업체는 1곳에 불과한 실정이나 니트류에 대한 지속적인 수요 증가를 고려하면 니트 소재에 대한 CPB염색 적용은 시의적절한 필수요소라고 판단된다. 니트 소재에 대한 CPB염색가공 적용 시 나타나는 문제점은 작업원단의 변부 말림현상 발생, 전폭 상태에서의 색상차이인 listing현상, 원단의 첫도입부분과 끝부분의 색상차이인 tailing현상이며, 반복되는 작업 시 염색재현성을 확보하는 것으로 나타난다. 본 연구에서는 CPB염색 시 CPB Head 장치의 Padding 방식 즉, trough와 Nip type에 따른 염색 시 알칼리와 염료 투입에 따른 염색 재현성(Build up, Ending, 알칼리 안정성)을 비교해 보았으며, 이에 따른 염색제품의 물성 및 견뢰도를 확인하여 보다 효율적인 방식을 선별하였다.
