The domestic textile industry is currently making an active effort to present high value-added materials that can respond immediately to the wants and needs of consumers sensitive to the of originality of design and emotionally appealing fashion materials. This paper attempted to present the creative development of materials in the contemporary clothing culture in which consumers' needs are individualized and differentiated and the cycle of life in fashion materials is getting shorter. To be specific, the paper presented the texture of peculiar expression to diverse cotton materials using the Woolsmok technique in the processing of felt. The chosen Merino wool was felted to 8 kinds of cotton with different density and structure. The touch, texture, visibility and complex susceptibilities of new materials were presented as different materials of cotton and wool were transformed into one material. In felting cotton fiber through wool, the transformation of diverse textures was presented and compared in the method using the washing machine in an attempt to enhance the efficiency of the traditional craft technique and work. This study proposed the possibility of placing the new material made up of cotton and wool beyond the range of functionality of each simple material, activating it as the peculiar material and expanding it to the range of its use as fashion material in the clothing industry. It is expected that this material will become competitive material at home and abroad by being activated as the clothing material of artistry, workability and marketability that can satisfy the tastes of consumers who call for high quality and diversification.

소재 개발의 프로세스가 고객 중심으로 다변화 되어가는 생활 환경 속에서 소비자의 감성과 선호도를 파악하는 것은 제품 판매 전략의 중요한 성공요소가 되고 있다. 본 연구에서는 사용자의 감성과 선호도를 중심으로 소재를 개발하는 방법의 하나로 협력적 필터링 개인화 기법을 응용하여 패션 디자인 추천 시스템(FDRS)을 제안한다. Textile 기반의 협력적 필터링 개인화 기술에서, 사용자들간의 유사도 가중치를 계산하기 위해서 피어슨 상판 계수(Pearson Correlation Coefficient)를 사용한다. 소재에 대한 사용자의 감성이나 선호도에 대한 Textile의 대표 감성 형용사를 추출함으로써 소재 개발을 위한 감성 형용사 데이타베이스를 구축한다. 패션 디자인 추천 시스템(FDRS)은 구축된 감성 형용사 데이타베이스를 기반으로 성향이 비슷한 사용자에게 Textile 디자인을 추천한다. 패션 디자인 추천 시스템으로 개발하여 시스템의 논리적 타당성과 유효성을 검증하기 위해 실험적인 적용을 시도하고자 한다.

In this study, when printed on a nylon material, the color strength and fastness are lower than that of a polyester material, and the nylon material shrinks due to heat and pressure, resulting in poor design and poor compatibility. To overcome this problem, we investigated the possibility of transfer DTP by adding pre-treatment process to nylon transfer DTP process. For the basic study of pre-treatment preparation, we used pure nylon material which is not compounded and dispersion ink and transfer paper applied to existing PET transfer DTP. Pre-treatment preparations were classified into three types of acryl-base polymer and pre-treated with nylon and then applied to transfer DTP to confirm their color strength and fastness. The color strength of the pre-treated nylon material increased and poly-methyl-acrylate amulsion pre-treatment showed the best color at $210^{\circ}C$, 1.5m/min and 0.3MPa. The nylon material pre-treated with washing, friction, and light fastness was judged to be more excellent and stable.

본 논문에서는 미시 및 중시 역학의 2-단계 해석 전략을 채택하여 유연직물 복합재료의 기계적 거동을 예측하였다. 미시역학에서는 섬유다발의 유효물성치를 계산하였고 그 결과를 이용해 중시역학에서 유연직물복합재료의 인장탄성계수를 예측하였다. 중시역학 해석 과정에서는 섬유다발의 회전 및 전단 대변형에 의한 기하학적 비선형성을 고려하기 위하여 사용자 정의 부프로그램을 개발하여 ABAQUS 내에 삽입하였다. 해석결과, 인장하중을 받는 유연직물복합재료의 응력-변형률은 비선형 거동을 보였고, 계산된 유효탄성계수는 시험값과 잘 일치하는 것으로 나타났다.

Polyurethane(PU) materials have been generally used in the automobile, paint, furniture, adhesive, and textile industries. The use of Waterborne PU was motivated form the environmental point of view, i.e. reduction of solvent emissions into the atmosphere(volatile organic compounds, VOC)[1]. Generally speaking, phase change materials (PCM) have the capability of absorbing or releasing thermal energy to reduce or eliminate heat transfer at the temperature range of the particular temperature stabilizing material[2].

This study examied ned physical properties and surface characteristics of papers post-processed by Jumchi technique and stainability of extract from Amur Cork-Tree to use Dakji as clothing material. Then, it found the following results. After-treatment by Amorphophalus konjac K. Koch and persimmon juice showed stronger tensile strength and tearing strength than untreated samples and the drape stiffness was substantially increased. After-treatment by persimmon juice generated dyeing effects as well as excellent tensile strength and tearing strength all samples were generally dyed well by Amur Cork-Tree, While the untreated samples did not show any significant effects in dyeing for more than 5 minutes. It was found that after-treatment substantially contributed on concentration of dyeing as dyeing amounts of post-processed samples were gradually increased as time increased. After-treated sample with agar did not show any significant differences from untreated sample. Accordingly, it has to be studied further.

We experimentally investigated the mechanical and electrical characteristics of the poly vinyl alcohol(PVA) hydrogel which have attracted special interest as a mechanochemical material, and the applicability of the hydrogel membrane to a sensor for measuring large strain. As a result, the PVA hydrogel could be regarded as a Hookean elastic material and was treated as an electric resistance which was proportional to the tensile strain within a linearly elastic range.

This paper investigates the influence of raw material and process parameters in spinning that affect the inter fiber cohesion in yams. An instrument has been developed for measuring the minimum twist of cohesion. With regard to the raw material parameters, the influence of different cotton fiber mixings for a given count of yarn is investigated. Also the effect of spinning to varying counts for a given cotton variety is studied. With regard to the process parameters, studies have been carried out to investigate the influence of noil extraction in comber, number of draw frame passages, draft pressure in ring frame and direction of twist. Cohesion improved with increase in the noil extraction percentage in the comber. Increase in the number of draw frame passages also improved the cohesion. Draft pressure in ring frame improved the fiber cohesion in yarn up to a pressure of $2.1kg/cm^2$. Direction of twist had no effect on the cohesion.

FTriphenylamine dye compound having diheteryl moiety was synthesized and its photoluminescent property was investigated. Organic luminescent materials have received great attentions due to potential application subjects onto full color image displays. In this context, the dye (III) for light emitting materials was synthesized using 2-(4-amino-2-hydroxyphenyl)benzoxazole (I) and 4,4'-diformyltriphenylamine (II). It is well known that the amino groups of compound (I) react with carbonyl groups, especially an aldehyde, to afford azomethine linkages. The dye shows bulish-green fluorescence property, which is anticipated for the light-emitting material for display devices. In this context, our aim is to synthesize diheteryl-substituted triphenylamine fluorescent dye as an emitting material. The spectroscopic characteristics and the fluorescent properties of this dye molecule were examined and determined.
