Unripe indigenous persimmons which contain rich tannins have been used as natural dye materials traditionally and have been using continuously for dyed clothes named Gal-ot in Jeju. Those persimmons were cheap and easy to use as dyes because of inedible and widely cultured in Korea. Persimmon juice dyes not only make fabrics brown-color but also give functional and hygienic properities such as stiffness, air ventilation of clothes, antibacterial activity, protectivity against ultraviolet light. However there are several serious problems which are ristriction of dyeing periods, longtime irradiation, uneven color and low color fastness etc. in persimmon juice dyeing. This study purpose to improve dye effect and method in order to enlarge useability of persimmon juice dyeing. Cotton fabrics were pad-dyed to 100% pick-up using padding machine after dipping in persimmon juice extracted from unripe persimmons indigenous from Jeju. It was possible and available to control pick-up rate. The color of dyed cotton fabrics by padding method was more even and repeatable than which by traditional hand method. Persimmon juice concentrations were 4 types of 10, 25, 50 and 100％. The more concentration increased, the more color deepened. UV Irradiation instead of sunlight was applied to color developing. Irradiation times were shortened till 1∼8 hrs. Same color values could be taken without water wetting which were required in sunlight irradiation. Tensile strengths of cotton fabrics pad-dyed with low concentration of persimmon juice decreased but recovered at high concentrations. Elongations(％) of cotton fabrics pad-dyed with persimmon juice were increased 1％ more than undyed cotton in sunlight irradiation. Drape stiffness increased upto double times as much as.

The purpose of this study is to examine how he successfully connected his ideas of fashion design for art with the commerciality without a conflict about for 40 years. It is expected that this study will be a precedent in the aspect of the symmetry between artistry and commercialization in Issey Miyake's works. We will examine Issey Miyake's idea of fashion design and its development for the commercialization since 1970s that he started to give shape to his ideas in the fashion works to exactly commercialize in the market. 1. Re-creation of tradition(a piece of cloth): throughout the 1970s, Miyake continued to experiment with a variety of Eastern design elements. The elements of Japanese or oriental tradition made him to be at the very center of supreme of the world of fashion. He took advantages of his identity, and developed the tradition for mass produce. 2. Design for mass(Pleats Please): Miyake decided to make clothes for the people, not only for the top class of the society. This thought developed the designs for the mass, which were functional, universal for the modem buyer, and accessible to a wide market. He realized his ideal by the medium of pleats, which were made through industrial processes, while he tried variously the aspect of formative of the pleats in the collections. His designs concept is summarized by the industrial product design and anonymous design. 3. Innovation of manufacturing system(A-POC): Miyake in 1999 developed A-POC. A-POC is used modern computers in conjunction with traditional technology. A-POC does not make only a new cloth but also makes a new manufacturing system of clothes.

Recently, functional clothes that can reduce deposition and/or penetration of fine dust have been developed. However, there are no methods to quantitatively evaluate the performance of these clothes. In this study, we developed a method to contaminate a fabric using fine dust and established an approach to quantitatively assess the degree of particle contamination on the fabric surface. Silicate powder was chosen as the particle to simulate fine dust because silicate particles are fluorescent under UV light; therefore, they can be distinguished from any color of non-fluorescent fabric surface. A camera with a high-resolution lens system was used to scan the surface of the contaminated fabric surface, and the degree of particle contamination of the fabric surface was analyzed in terms of the pixels corresponding to the area of the fabric surface contaminated by silicate particles. Finished or unfinished nylon fabrics as well as cotton fabrics were contaminated with silicate particles, and their surfaces were scanned using the established camera. The proposed assessment method was found to be useful for quantitatively comparing the degree of particle contamination of the fabrics.

This research developed maternity wear designed with a focus on the essential functions necessary for working women and adaptable to their body changes during pregnancy. Through Martin's anthropometry for 201 pregnant women, the size specifications for maternity wear was determined and a dress form was proposed, in order to provide the manufacturer with reference data and a prototype to verify their products' fit and suitability. From a monthly analysis on the body measurements of pregnant women, significant monthly differences and after pregnancy were found in weight, chest girth, bust girth, under bust girth, waist girth, and hip girth. Dress form was designed based on the average body measurements of women in their 6th to 10th month of pregnancy. The standard dimensions in the 8th month were 90cm (chest), 94cm (bust), 86cm (under bust), 97cm(waist: most protruding part on the side), and 99cm (hip). Compared with Japan's MAT-9 (for nine months), chest girth was the same, while the Korean waist girth and hip girth were larger by 2cm and 3cm, respectively. The woven fabric blouse was evaluated as having the best appearance, while the knitted fabric one was judged as being more comfortable it terms of functionality. For the pants, the design details of the lowered waist and curved waist belt were more functional. The tailored jacket was the best design for working women in terms of both looks and functionality. To summarize, maternity wear for working women, unlike general maternity clothes, should be designed with consideration for the wearer's somatotype and activity. Elastic materials were appropriate for functionality and dealing with physical changes. With the increasing of working pregnant women, such trials are expected to continue in this research area in order to develop functional maternity wear with multi-purposes such as breast-feeding, wearability after delivery and shielding from microwave.

Since smart devices are able to efficiently provide information without barriers of time and location, they are widely utilized with advent of the hyper-connected society. Especially, the smart devices have been developed in the form of wearable devices for mutual interaction between human and objects. Smart clothing, which embeds smart devices within clothes, measures and obtains a variety of bio-signals as it is in close contact with the human bodies. Conventional smart clothing generated wearers' discomfort because they were developed by simple attachment of electronic devices to clothes. Therefore, it is highly recommended to develop novel smart clothing based on smart textiles which integrate electronic devices as parts of textiles. As smart watches are currently the most available wearable devices in the market, smart watch users were selected in this study, for the purpose of investigating core needs of wearable smart device users based on the user experience and user's sensibility. Qualitative research was performed through semi-structured interview in order to obtain detailed answers about user sensibility based on smart watch user experience. After the in-depth interview, the user's sensibility was categorized into four aspects; functional, aesthetic, social, and empirical. Sensibility adjectives and key words were assigned to each aspect and their frequency was analyzed. It was the functional aspect of sensibility that the wearable device users require the most. The results of this study will be utilized as a fundamental data to develop the smart textiles required for the next generation of smart clothing which is attracting as a future wearable device.
