The purpose of this study was to research about Dobby weave design using Computer-Aided Weaving System. For performing this design study, first, it was researched the characteristics of the classified woven fabrics, weaving processing, structure of Dobby loom, and Computer-Aided Dobby Weaving system theoretically. To develop Dobby woven design, Patternland Weave Simulator(U.S.A) for computer weave system was used. Among the developed Dobby woven designs by computer weaving system, mainly three of them were selected and woven into Dobby loom. To see the visual image of the fabric end-use, some of the scanned Dobby fabrics were simulated to the three-dimensional virtual images by Alias CAD system. The result of this study can be summarized as follows. Before the step of weaving Dobby fabrics on the woven design works, Computer-Aided Weaving system can be done very easily to apply the design step of Dobby woven fabrics, specially in case of the complicated woven structure. Also the usage of the simulation CAD system in visual image of the final products, ultimately can be saved cost and developed the higher value-added goods in more response to consumer demands.

Computer development and new printing technology allow us to express a new type of digital textile designs those were not possible in the past. In this study, watercolor overlaying effect of various colors was tried using airbrush tool in Photoshop program. Photoshop program is a powerful graphic tool and can be used in textile design area to generate various types of designs. Woven texture was also applied to the design to give yarn dyed effects or rich appearance. Photoshop program was also used to develop woven texture without the help of the professional textile CAD. Photoshop channels enables the designers to apply various textures to the image. Plain weave and houndstooth were applied in this study. Colorways of the developed designs having watercolor effect and woven texture by applying Photoshop color adjustment function. Quick and simultaneous changes of colors were possible using this method. The developed textile designs were printed by transfer DTP. Successful textile design prints were expressed and showed watercolor overlaying effect and woven texture. The printed textiles show a little brighter color, and therefore, sample printing is recommendable in case of color sensitive production.

The functional non-woven fabrics have been applied in various industry fields, such as clothing, hygiene, environment, medical and so forth. The functional non-woven fabrics were manufactured by meltblown and finishing processes. These functional non-woven fabrics were based on 5wt% masterbatch using 2,000ppm nano-silver resin composite. Silver is one of the most universal antimicrobial substances. Nano-technology enables us to expand the surface area of silver particles markedly. Silver nano particles were successfully produced less than 50nm in size. The functional non-woven fabrics including nano-silver particles showed excellent antibacterial activities against Staphylococcus aureus (ATCC 6538) and Klebsieila pneumoniae (ATCC 4352). From the results, functional non-woven fabrics including silver nano particels probably will be available as a good and safe antibiotic alternative, such as mask medium filter, water purifier filter, hygiene wet tissues, marine products pad and so forth.

Reliable three-dimensional models of woven fabric composites had scarcely been proposed for their geometric complexity. Simplified models, mostly one- or two-dimensional, currently used are not considered effective enough because of their oversimplifications. In this paper, the equivalent thermal conductivities and elasticity properties of woven fabric composites are computed using homogenization technique. The computational results show that the strength and thermal conductivity linearly increase with fiber volume fraction and that the variations of undulation of fibers has little effect on equivalent material properties. Homogenization technique is proved useful in the study of woven fabric composites and may find a lot more applications in the area.

This study aims to analyze the physical properties of non-woven fabric sheets, which continue to grow in the cosmetic market. Non-woven fabric sheets were used as specimens, and a total of 17 samples were analyzed. To evaluate the physical properties of the non-woven fabric sheet, the weight, tensile strength, surface properties, free swell absorption, and wet stiffness were tested. Through the results itw was determined that non-woven fabric sheets for mask packs should be manufactured considering fiber arrangement so that the weight is 40 g/m², and the tensile strength should be maintained near 12 kgf. In addition, it was confirmed that the material selection and process conditions should be adjusted so that the free swell absorption is at least 8 g/g, and the wet stiffness is 200 mg. Therefore, since the non-woven fabrics for the mask sheets can be used in various products depending on fabric composition, this study will be expected to be basic data for the continuous growth of the sheet-type mask packs coming to market.

본 논문에서는 3차원 엮임 재료의 재료 물성치들을 효율적으로 분석하고 추후 최적설계 연구에 활용하기 위해서 파라메트릭 배치 해석 워크플로우를 제시하였다. 3차원 엮임 재료를 구성하는 와이어들 사이의 간격을 설계 매개변수로 하는 파라메트릭 모델에 대해서 임의의 변수 조합을 가지는 2,500개의 수치 모델을 생성하였으며, 상용 프로그램인 매트랩과 앤시스의 여러 모듈을 사용하여 체적탄성계수, 열전도도, 유체투과율과 같은 다양한 재료 물성치들을 배치 해석을 통해서 자동으로 얻어질 수 있도록 구성하였다. 이와 같이 얻어진 대용량의 재료 물성치 데이터베이스를 활용해서 회귀 분석을 수행하였으며, 그 결과 설계 변수들과 재료 물성치 사이의 경향성과 수치 해석 결과의 정확도를 검증하였다. 또한 확보된 데이터베이스를 통해서 3차원 엮임 재료의 물성치를 예측할 수 있는 인공 신경망을 구성하고 학습시켰으며, 그 결과 임의의 설계 매개변수 값들을 가지는 엮임 재료 모델에 대해서 구조 및 유체해석 과정 없이도 높은 정확도로 재료 물성치들을 추정할 수 있음을 확인하였다.

The merits of activated carbon for removal of organic compounds have been well known in the various industrial fields. Fixing methods with activated carbon in the non-woven fabric have the advantages of fast adsorption and ease of handling when compared with bonding and coating methods. In this study, we have examined deodorization of non-woven fabrics fixed with activated carbon. We have been tested the deodorization of various kinds activated carbon and non-woven fabric structures. The effective mixing ratio of activated carbon was 5% on the weight of fabrics, which are closely related to the fabric structure. The activated carbon with higher mesh size show the better deodorization effect.

The purpose of this study was to determine the thermal characteristics of men's suits ensembles and their fabrics. For the study, 100% wool fabrics were woven with various fabric structure, fabric density and yam count and With the use of these, 12 men's suits were made with the same design. Physical characteristics that affect thermal transport properties, including drapery, cover factor; bulk density, keeping warmth ratio, vapor permeability, air permeability and porosity of the fabrics were measured. In addition, thermal resistance of men's suit ensembles, including Y-shirts, inner wear and socks was measured on the thermal manikin in the environmental chamber. The result of the study was as follows: 1. In terms of fabric structure, keeping warmth ratio of plain woven fabrics was higher than those of twill and satin woven fabrics and also, vapor and air permeability and porosity of plain woven fabrics were higher than those of twill and satin woven fabrics. 2. The result showed that thermal resistance of 12 ensembles were in the range of 0.77clo~0.97clo. 3. There was little correlation between woven condition such as, including structure, fabric density and yam count and thermal resistance of ensembles.

In this study, thermoplastic urethane (TPU) coating yarns were prepared at various extruding temperatures. The fine structure and mechanical properties of resultant TPU coating yarns examined by the wide angle X-ray diffractometer (WAXD), differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), and tensile test. TPU coating yarns (prepared at extruding temperatures at $175^{\circ}C$) were confirmed as a stable fine structure that obtained excellent tensile strength and flexibility. The C samples prepared by optimized conditions made by TPU woven floor mat. The structure of the woven mat is $4{\times}4$ basket weave and have laminated with the EVA foam to obtained final TPU woven floor mat products. The resultant TPU woven floor mat was obtained to 1.5MN of tensile strength, 22% of the elongation, and 0.2MN of tear strength. The weight loss abrasion and the resilience by the ball rebound of the TPU-woven floor mat was prior to those of the PVC subsequently, we were able to develop a woven floor mat with TPU coating yarn and produce an eco-friendly high valuable woven floor mat using an interior product.
