The purpose of this study was to analysis of design preference according to age of consumers in order to obtain basic informations which are necessary for the development of designs that can satisfy the needs and desire of Chinese consumers. The style, color, fabric pattern, fabric, image, and shape of clothing were used for design preference variations. The study was implemented by surveying 280 females living in Beijing, China. The results were as follows: 1) There were significant differences in the preference of style of outdoor clothes according to age. Chinese women in the age of twenties and fifties prefer to wear casual clothes. Preference ratio was more than 60% 2) There were significant differences in the preference of color of spring and summer clothes, but there was no difference in the preference of color of autumn and winter clothes. 3) There was a difference in the preference of fabric pattern of outdoor clothes. Generally Chinese women showed 50% of preference for the no patterned outdoor clothes. 4) There were no differences in the preference of fabric materials. Preferred material for spring and summer was cotton fabrics, and that for autumn and winter was woolen fabrics. 5) In the research of the preferred image of outdoor clothes, generally Chinese women showed the most preference for elegance style. Chines women who are in the age of thirties to forties preferred feminine style. However, Chinese women who are in the age of fifties like to choose simple style. 6) There was a significant difference in the preference of length of jacket and skirt, and generally Chinese women preferred to wear medium length of jacket and skirt. There was no difference in the preference of design of collar and shape of pants. However most Chinese women showed preference for tailored collar and straight shaped pants.

Experimental research is needed to provide information on the removal of bloodstains since washing clothes contaminated with blood is necessary for medical related fields (such as ambulance workers and doctors) as well as for women of childbearing age. This study investigated efficient washing conditions for the removal of bloodstains with a focus on washing temperature, fiber type and blood ageing time. Polyester/cotton fabric showed the highest detergency from among three fabrics that were influenced by the composition of the fiber and the structure of the yarn and fabric. When examining the effect of detergent, it was concluded that the alkalinity over pH 10 was essential to remove bloodstains and that auxiliary agents such as soil antiredeposition agents and bleach had a significant effect on the removal of bloodstains. Washing temperature showed the highest detergency at 20℃ due to the activity of the enzyme without the denaturalization of blood. Blood-ageing influenced detergency by inducing changes in the adsorption area and chemical bond. A combination of methods such as quick removal after contamination, use of alkaline detergents including soil antiredeposition agents and bleach, and low-temperature washing could help remove bloodstains.

In order to analysis on color difference of yellow natural dyes, I have dyed cellulose and protein fabrics. The results of experiment have been analysed by wavelength of maximum absorption, amounts of dye uptake, color difference, Hunter's value and Munsell's value. The results from these analyses are as follows : Bud of pagoda tree, Amur cork, and Curcuma showed greenish yellow color, Gardenia Jasminoides showed reddish yellow color. Barberry root showed reddish yellow color with post-mordanting method on cellulose fabric. Moreover, Dupioni silk was dyed in reddish yellow color by Barberry root and Rhubarb. In addition to Chroma index, Gardenia Jasminoides and Curcuma showed clear color overall. However, dyeing rayon and silk by Barberry root, and dyeing silk by Rhubarb showed clear color. Comparing all the results to actual dyed materials, Bud of pagoda tree had small dye uptake, and both ${\Delta}a$ and ${\Delta}b$ value were short which can't recognized the yellow color easily. Dye uptake of Amur cork and Gardenia Jasminoides was small just like Bud of pagoda tree. However, ${\Delta}b$ value order was Gardenia Jasminoides>Amur cork>Bud of pagoda tree. Therefore, Gardenia Jasminoides recognized reddish yellow because of big value of red color and yellow color. In case of Barberry root and Rhubarb which have larger dye uptake, Baberry root recognized yellow color on rayon only, and couldn't recognized yellow color on bleached cotton fabric, ramie, silk, and dupioni silk. Rhubarb recognized yellow color on rayon with pre-mordanting method only, but recognized silk and dupioni silk as brown like color. Moreover, we could not analyze color by dye uptake, Lab, and H(v/c) for Barberry root and Rhubarb. As a result, I think we need to attach color table for the research paper which handled the color of dyeing materials.

The purpose of this study is to perform research of ecology concepts expressed in fashion and to propose a new ecology fashion design based on the results. As a specific research method, first, to determine the concept of ecology, the contents related to ecology were extracted and organized through literature research, and then a fashion collection research was conducted to acquire basic design data, such as silhouettes, materials, details, and colors. From WGSN, and a total of 57 images were selected and used as basic data for the design suggestions. As a result of collecting the collection images, it was found that cotton or denim fabrics were mainly used, and in particular, the frequency of use was high mainly for bright tones. The use of chambray, lace, and wrinkles, was also frequent, and the use of expression techniques using burn-out, bleach, and bleaching effects or parts, or entire dyeing was often noticeable. The colors showed neutral and pastel-toned characteristics, and the silhouette was mainly composed of long silhouettes centered on maxi, such as a top or calf based on the knee, rather than a mini. Fabrics for the final designs were linen and sappan wood, and they were used for the dye and red was used as the overall color. The silhouettes were simplified, and care was taken to prevent unnecessary waste, such as paper or materials, from being generated during the production stage. We tried to achieve the purpose of eco-logy by refraining from excessive trimming, except for essential subsidiary materials, such as zippers.

Digital Textile Printing(DTP) is appropriate for quick response system(QRS) and is closely connected with high value added fashion industry. Fashion products of high price are mainly silk and cotton. For high quality DTP products, it is important to optimize the parameters of media, pre and after-treatment, ink, printer, etc. DTP for these two fiber materials is also accompanied certainly with steaming as after-treatment process for coloration. Role of steam is like water in exhaustion dyeing. Steam can diffuse dye or ink in printing paste to fiber. Quality of DTP products depend on after-treatment processes such as steaming, washing, drying. Current production amount of DTP is smaller than one of conventional textile printing. However conventional after-treatment system has been using so far. This is mismatched with DTP in terms of process efficiency, spot work of small lot, quality control. In this study, continuous after-treatment system has been suitably designed for DTP that washing and drying are available after steaming. So, It is possible to improve efficiency of DTP process. Especially, the effects of after-treatment process, such as temperature of heat drum, steaming time on printability, color difference, color fastness were examined. Two types of samples(cotton knit and silk fabrics) were used. The results were obtained as follows : First, there is no a wide difference between the K/S values of cotton and silk treated with continuous after-treatment system and those of sample treated with conventional printing after-treatment method. So it is more effective to use the continuous after-treatment system than conventional printing after-treatment system in case of the daily throughput of 1,000 yards below. Second, after continuous after-treatment for DTP, K/S values were increased and lightness($L^*$) values were decreased. ${\Delta}E$ values were below 2.3. Third, DTP samples treated with continuous after-treatment system were tested for fastness(washing, light, rubbing). Grades of fastness(washing, light, rubbing) were above 3 grade.

In the textile culture of the Joseon Dynasty, the historic record of Banpo is fragmentary and contains many missing details. The main reason is a lack of associated literature, and it is also significant that the actual substance used is not clear at present. Banpo is a kind of cotton, but this has not been confirmed in the traditional textiles that are currently handed down. The word Ban [斑] in Banpo means "stain", and the letter Po [布] means "fabric". At the border of white discourse, Banpo did not receive attention as a research topic. This study is an attempt to restore some of the textile culture of the Joseon Dynasty through Banpo. Banpo is not just limited to the Joseon Dynasty; it is an important material for examining the development of textile culture and exchange in East Asia. This study was broadly divided into three parts. First, the record and meaning of Banpo during the Joseon Dynasty were examined. Records of Banpo can be seen from the early Joseon period during King Sejo and Seongjong, and the production and actual use of Banpo have been confirmed. Banpo was maintained until the beginning of the 20^th century, but is no longer observed. Banpo is a woven fabric made of cotton yarn dyed in many colors and has appeared in Southeast Asia since ancient times. In East Asia, there are other fabrics similar to Banpo, such as Ho [縞], Sum [纖], and Chim [綅]. In particular, the correlation between Banpo and Ho is an important link in understanding Banpo in the Joseon Dynasty. Second, the meaning of Banpo was examined from various angles through comprehensive analysis of Chinese and Japanese literature records and cases. The appearance and development of Banpo moved in sync with the period when cotton was introduced into East Asia. In East Asia, cotton was introduced and produced in earnest from the end of the Song Dynasty to the beginning of the Yuan Dynasty, and the meaning of Banpo was diversified. In China, the name of Banpo was changed to Hwapo [花布], Gizapo [碁子布], Gizahwapo [棋子花布], etc. Japan was late to introduce cotton and developed it in acceptance of the changed meaning. In Japan, use of the name Banpo is not on record, but a Ryujo [柳條] fabric of the same type as banpo has been identified. This Ryujo is the same concept as Ho and Hwapo, and later merged into Ho. Names such as Ho, Hwapo, Banpo, etc. were used differently in each country, but the form was shared across East Asia. Third, based on the meaning of Banpo shared in East Asia, the format of Banpo in the Joseon Dynasty was classified. The format of Banpo in the Joseon Dynasty can be divided into grid and striped versions. The name Banpo disappeared over time, but the form remained and was passed down until recently. I hope that this study will help restore Banpo in the future.

The purpose of this study is to develop knitwear design expressed not also Green but also LOHAS using natural yarns(wool and cotton) dyed with various natural sources(sappanwood, indigo plant, turmeric, cochineal, coffee, gallnut, and persimmon juice). This researcher tried to suggest solution scheme through the development of knitwear designs to break from the cottage industry and the limitation of design in Jeju and to preserve of traditional dye with persimmon juice simultaneously. Knitting is the formation of a fabric by the interlooping of one or more sets of yarns with hand knitting or industrial knitting. In hand-knitting, the two fundamental stitches are described as knit depending on the direction of the loop formation, front to back or back to front. In machine-knitting, the direction of loop formation is fixed, unless the stitch is mechanically transferred from front to back needle bed or vice versa. Industrial knitting technology can be divided into two main areas - weft knitting and warp knitting. Each has a different principle of construction. The majority of knitted fabrics for clothing are weft-knitted, and so this study is used weft-knitting and hand knitting technology. To achieve this purpose, researcher tried to present a lot of knitwear designs using yarns dyed with various natural sources focusing on Modern & Sophisticated Image and Elegance & Romantic Image to satisfy adult and missy consumer needs.

This study reviewed the differences among Onggis made in Jeju and other areas, developed creative textile designs and cultural products, and conducted the consumer evaluation of developed products. First, the 1,063 photos of Onggis made before the first part of the 20th century were collected and the unique differences of Jeju Onggis were confirmed through the observation of collected photos. Second, based on the uniqueness of Jeju Onggis, the eight pieces of Jeju Onggis were selected from the photos and used as pattern design motifs. Nine basic patterns were drawn and ten textile designs were created using the basic patterns. Third, the 16 pieces of textile products were made with cotton fabrics on which the textile designs were printed. Four mugs and four tumblers with printed patterns were also made. Finally, 64 students evaluated the developed products using a 7-point scale. As a result, folksy atmosphere, uniqueness, usage as a Jeju souvenir and at local restaurants, and the role of fostering concern for Jeju Onggi were highly evaluated but aesthetics was rated relatively low. Most of the developed products were highly preferred and recommended as Jeju souvenirs or for local restaurants.

This study was aimed at investigating the satisfaction in relation to clothing design and size-fit for nurse uniform in Korea. The subjects were 986 female nurses working in 12 hospitals selected by convenience sampling. The data were collected by questionnaires. Using SPSS package, frequency, percentage, t-test, ANOVA and SNK test were conducted. The results were divided into 2 categories as fellows; 1) Results of the satisfaction with the size-fit and size system of the nurse uniforms : Nurses satisfied at the individual size-fit system than ready-made size system. There was a considerable difference of the satisfaction with the size-fit depending on age and clinical career. And more than half of nurses were needed the concrete and precise size system. 2) Results of the actual design condition and clothing satisfaction : Nurses wore two-piece pants suits more than classical designed one-piece style. The princess-line, convertible collar and yoke design were preferred for nurse uniform with the high satisfaction. 41.6 percent of respondents used the cap obligatory and the white color and a patterned textile were generally used. The used fabrics were only polyester and cotton/polyester mixed spinning.

The environment and green are critical issues for businesses in the $21^{st}$ century. This study examines product assortments of eco-friendly products, green marketing strategies, and the marketability of Trashion products among fashion brands. Data were collected through an interview method from eight fashion brands that were actively conducting green marketing. The general activities of green marketing were to produce eco-friendly products and/or an economical support for environmental groups or green conservation campaigns. Eco-friendly products included organic cotton products, well-being products made of bamboo or beans, goods made of recycled plastic bottles, and Trashion items. The first reason was to improve the brand image, then take social responsibility, and last participate in the environmental movement. However, the price of green products and supplies of eco-friendly fabrics were the most challenging issues for fashion businesses. The marketability of Trashion products was directly opposed and managerial implications for green marketers were discussed.
