Radio Frequency Identification(RFID) can provide visibility and efficiency throughout the entire supply chain in fashion apparel and footwear. The technical analysis of RFID performance is necessarily required to create a sealess omni-channel service using customer experience. Especially, several tagged-item performance specifications, for example read range and multi-read rate, strongly depend on the attached material and real-operating environment. This paper suggests minimum performance requirements for RFID tags embedded inside a pair of shoes to negotiate tagged-item performance between retailers and suppliers.

With the advent of industrial society, the phenomenon of nuclear families has brought many changes in the family environment. Of changes, a decrease in the number of new-born babies led to one-child families, which then led to an increase in interest in children. Interest in children gave birth to a consumptive trend called "kids marketing," and phenomena of generous investment and consumption for children appear to continue to the future. In reality, too, the consumer market of children's apparel and learning materials for children has sharply increased over the past few years, and products related to children have become the center of family consumptions. Therefore, at this point when children are the center of consumptive life in the family and the relationship between products and users is becoming an increasingly more important variable, the conductive research focusing on children is necessary. These important factors embraced wide areas of activities in research on children, from children's physical changes, children's preference, such as color and material, to children's consumptive environment, as they can provide a foundation for furniture design suitable for children.

This study investigated the store switching behavior of fashion stores targeting college students. A random sample of college students completed a questionnaire that contained measurements of store property, relationship quality, switching intent of store, preference of on/offline store, purchase of brand/non-brand product and monthly clothing expenses. The factors extracted as switching behavior of on/offline fashion store are store property, relationship quality and switching intent of store. Dimensions of store switching behavior in online shopping mall is revealed to be composed of diversity/ easy to search, store reliability, home page layout, sales promotion, reliability, commitment and switching intent of store. Also those of offline store is revealed to be composed of store comfort/salespeople service, product diversity, store location, product price, reliability, commitment and switching intent of store. The significant differences were found between store switching behavior of college students by preference of on/offline store and purchase of national brand/non brand. It is expected that this results can be used as a basic material for further study and setting up the fashion retailing strategies in fashion store for selling non brand products.

Rayon fiber as clothing material has silk-like property which relates to other synthetic fibers. It has many advantages that is required to women's clothes. However rayon has many shortcomings. Therefore this research is to spin rayon-like polyester which has high contraction property to be synthesized by previous research to solve those shortcomings and to maintain advantages of rayon. The contraction ratio of regular polyester is 30% and the contraction ratio of this synthesized polyester is over 60%. The spinning temperature of regular polyester ranges from $285^{\circ}C$ to $300^{\circ}C$. However, this copolymer is set range from $270^{\circ}C$ to $290^{\circ}C$, which is $10^{\circ}C$ less than regular polyester due to decreasing melting temperature. The spinning velocity effects the tensile strength and elongation of yarn magnificently. The high velocity of spinning makes yarn highly oriented, increases the tensile strength and decreases the elongation. This research defines the condition as following; draw ratio 2.734, First roller temperature $85^{\circ}C$, Slit heater temperature $175^{\circ}C$.

This study, by analyzing previous studies, aimed to understand how 3D printing technology is applied and utilized in the fashion industry and to contribute to encouraging further studies on 3D printing technology in the fashion sector and suggesting proper ways for designing such studies. Firstly, 47 papers were selected from all literature concerning 3D printing technology published in 15 journals of fashion and design since 2013. Afterwards, these papers were analyzed with regard to the frequency, topics or sectors, and purposes or types of studies shown by outcomes. Results were as follows: First, the number of papers on 3D printing technology published in the journals was counted according to the year, which showed that this number increased rapidly after 2015 for about 3 years. Especially in the year 2016, this increase was quite notable. Although a little decrease in this number was found afterwards, a steady increase was highly expected. Out of the 8 journals, Journal of The Korean Society of Fashion Design had the maximum papers. Regarding areas of studies, works on designing and development of products were most common. Finally, regarding the purpose of studies, those suggesting or presenting apparel were predominant. Product items included clothes, shoes, and caps. Studies on caps mostly covered designing the products. Studies on clothes aimed at designing, characteristics of construction, and case study. However, there were very few works on 3D printing technology as an alternative material or composition of clothing.

This study aims to provide basic data to suggest guidelines for re-education and work improvement of modelists based on the analysis of the current status of modelist work and education. A survey was conducted from January 4 to May 15, 2020, targeting 44 people working in pattern, pattern CAD, and grading in domestic apparel companies. Descriptive statistical analysis and frequency analysis using SPSS 25 were employed to analyze the status of work type, work difficulties, and re-education. For pattern production, the rate of using pattern CAD for business was high. It was found that companies mainly use YUKA CAD (63.8%), and branded companies use pattern CAD (100%). It was found that 3D CAD is mostly employed by vendors (88.9%), and CLO (90%) is mainly used. Regarding difficulties in pattern making, it was found that they experienced difficulties with stretchable materials owing to the amount of shrinkage and sagging of the fabric. The work problem was the lack of requisite working hours owing to the volume of work. Regarding future re-education, 63.6% of the total respondents indicated that they required a course related to pattern correction and material. Moreover, it was found that re-education was necessary to upgrade technology and acquire new knowledge, however, information on re-education was insufficient.

The subjects of ttis study were middle-aged women in their 40s$\sim$50s and older women aged 60 and over who were living in Seoul and Kyonggi-do, Korea. Through studying the participants' responses to the questions regarding the attributes of image preference in terms of the levels of satisfaction and importance, the target consumers' demand has been studied. And, they are applied to a QFD Matrix, to find out the relationship between the attributes of product quality and the guidelines of clothing design. For this study, clothing image preference is categorized as three types: fashionable and urbane image, elegant and formal image, comfortable and active image. It has also been found that middle-aged and older women think the clothing that projects fashionable and urbane image needs more improvement that those for other images. To review demands for the clothing image preference attribute of formal suits for middle-aged and older women, the priority of these attributes through QFD Matrix that shows the relationship between the attributes and dress elements emphasized by designers has been examined. In reflecting clothing image preference by consumers for their formal two-piece suits, the most important design elements related to material in order of importance were material type, style, thickness and texture, and those related to color were the number of colors used and coloring type.

The effects of removal of lignin or hemicellulose on the cottonizing and pulping characteristics of kenaf fiber were studied by comparing the conditions of non-cellulosic material contents, fiber lengths and dyeability. And the effects of lignin or hemicellulose on dyeability of the kenaf fiber using CI Direct Green 26 and CI Direct Red 81 were investigated. The results were as follows. The lignin contents decreased and the kenaf fiber became shorter and finer as the reaction time with sodium chlorite increased. The hemicellulose could be removed by treating sodium hydroxide solution to the fiber from which the lignin partly removed. The 80% of hemicellulose could be removed by 5% of sodium hydroxide solution in 5 minutes. But if lignin were not removed at all, hemicellulose could not be removed. The fiber lengths proper for apparel were obtained after treating sodium chlorite for 10-20 minutes and those for pulping were obtained after treating sodium chlorite for 40 minutes. The kenaf fibers from which lignin and hemicellulose partly removed were dyed with CI Direct Green 26 and CI Direct Red 81. Their dyeability increased as the removal rates of lignin increased. The ${\Delta}E$ values of kenaf fiber dyed with CI Direct Green 26 were lower than CI Direct Red 81.

Three materials for sport underwear were manufactured by order for study, and among them, suitable material in order to perform an experiment on the effect of wearing was adopted. The results are as follows: The result of wearing an experimental clothes for sports manufactured as a foundation-type underwear for sports showed that if the same compositional materials were applied, laminating material had higher rate than that of others in the amount of sweat. Concerning relative humidity in clothes and the amount of sweat absorbed in clothes among the two kinds of materials which were produced by laminate, material 2(nylon+modal) was statistically exerts higher influence on the amount of sweat. The humidity in clothes keeps the optimal condition of 59.8%, and breast part showed the highest relative humidity. The material 2(nylon+modal) showed the highest comfortableness, the sense of warmth, humidity and voluminousness, and the sense of pressure. Follow-up survey revealed that in case of material 2, higher amount of sweat than that of the group objects in its early phase, and the amount of sweat varies from individuals. The temperature in clothes of folded parts of experimental clothes and maximum surface temperature was equivalent to that of average skin. With the lapse of time, the weight decreased of 11.03% in maximum, and 3.12% in minimum. The amount of change in the girth was greater in part of body frame than that of limbs, and especially, navel and waist part showed high decrease, and upper breast, breast and the largest part of abdomen showed relatively low decrease. The above experiment revealed that materials for suitable to the underwear for sports for loss of weight by an exercise should be made of doubled-nylon and modal, along with the laminate processing, which heightens the amount of sweat. Thus, wearing an experimental wear gave satisfaction in the view of the beauty of appearance as it did not discharge flowing secretion to the outside at the time of exercise.
