The increased average life expectancy and an aging society mean a lot of change socially and economically. With the increased population of the new elderly generation, holding a desire to pursue high quality life, plans and marketing strategies towards this group have progressed in the clothing industry. Purchases of clothing will lead the silver clothing industry to a huge consumer market and silver clothing brands are expected to have a lot of potential to grow, especially in department stores in Korea. From now on, there is a need for attacking the market with distinct tactics and characteristics that will satisfy the elderly consumers emotionally. Psychological views towards the elderly generation must be changed and our unique environment state must be considered. With all that, there is also a strong need for researches and development technically and industrially.

In Korea, to deal with the housing needs of the elderly, the government operates free nursing homes and residential homes. And to deal with the needs for daily necessities, imported products or products for the disabled have been supplied for the elderly. The government has recognized the importance of silver industry in this rapidly aging society and has established strategies to vitalize industries related to seniors to deal with the seniors' need for food, clothing, and shelter. This study examined the necessity of nursing home gowns, and the development of nursing home gowns that are environmentally friendly, beautiful and functional for the new silver generation. For this study, literature review and Internet search were conducted regarding the status of silver fashion, necessity of nursing home gowns, emergence of new silver generation and change in lifestyle, and value and utilization of natural dye and traditional patterns. To produce nursing home gowns, fabric was dyed using fermented indigo dying, and 3 styles of nursing home gowns for each gender were designed in consideration of seasons. Lastly, these gowns were evaluated by fashion experts, medical personnel, hospital gown and silver wear experts, and natural dye experts. The results showed that the traditional Korean designs developed in this study were excellent and the fermented indigo dye was appropriate for the nursing home gowns. The development of nursing home gowns in this study will be utilized as basic material for the development of silver wear and nursing home gowns to improve the quality of life for the seniors.

Recent advances in electronic technology have engendered a need for research on the use of smart materials in clothing. Electro-conductive fibers are expected to be a crucial element of wearable devices. Therefore, in this study, we have attempted to develop electro-conductive threads and cables using silver nanowires. Based on the characteristics of silver nanowire, in which electro-conductivity can be imparted via heat treatment, we prepared conductive threads by coating nylon yarn with silver nanowires and curing at temperatures of 140℃, 150℃, and 160℃. Conductive threads cured at 140℃ had the highest conductivity, followed by threads cured at 160℃ and 150℃ respectively. The order of the electrical conductivity of the threads after tensile testing was consistent with the original order of the conductivity of the threads. When we evaluated the sensing performance of electro-conductive cables fabricated from these threads, the cables manufactured from threads cured at 140℃ and 160℃ were found to function normally within temperature and humidity sensors. All the cables operated normally in illuminance and electrocardiogram sensors. Thus, we believe that threads made of silver nanowire have sufficient electrical conductivity to be utilized as wearable sensors.

This study examined the difference in the mechanical properties of cotton fabrics treated with nano silver. Nano silver powder, UV-absorber, and DMDHEU are applied to cotton fabrics. The reagents added in a finishing solution were Triton X-100 and $MgCl_2$ $6H_2O$. The mechanical properties of the fabrics were measured by KES-FB system. From these, the primary hand values were evaluated by the conversion equation (KN-202-DS). The results of this study are summarized as follows. The fabric tensile properties and bending properties are increased by the application of nano silver, DMDHEU, and UV-absorber mixed. The values of tensile properties in the warp direction were significantly lower than those in the weft direction. However, the values of bending properties in the warp direction were higher than those in the weft direction. The differences in the values of compression parameters by nano silver coating were unnoticeable. However, the compression energy and resilience of compression in each fabric was increased by DMDHEU treatment. The SMD values of cotton fabrics are decreased by nano silver, DMDHEU, and UV-absorber mixed treatment.

In this paper, silver slit yarns combined with cotton yarns were used to produce weft knits. The purpose of this study was to investigate the physical properties as well as the functional properties of weft knit with silver slit yarns. The six different weft knit fabrics were made from silver slit yarns varying knit structure and fabric density. One cotton weft knit was also knitted to compare the properties. Weft knits made from silver slit yarns were characterized by excellent antibacterial properties, electric magnetic shielding properties, UV-cut properties, anti-static properties, and air permeability. Although there were significant differences in the physical properties of different knit structure and the fabric density, weft knits with silver slit yarns were seen to have better end use properties and ideal for apparel than the cotton weft knits.

The purpose of this study is to grasp the actual condition toward the clothing of senior males' and perception of male's formal wear companies for silver market through a survey targeting senior males and clothing companies. The survey was conducted targeting 196 senior males and chief-patterners of 7 companies' 10 brands. The questionnaire distributed to senior males was consisted of 22 items regarding the perception and satisfaction on clothes. And 12 items concerning the perception of senior male clothing brands and the size system was developed for clothing companies. The results of the study are as follows. The study revealed that most senior males perceived that brand clothing for them was necessary. More than half of the respondents were not satisfied with ready-made clothes. And many senior males prefer ready-made clothing when they purchase their clothes. For these reasons, senior males apparel market might be promising. Currently, the perception of male's formal wear companies on the need of brand was high. However, considering that brand launching might be difficult to be realized soon I presume that size spectrum based on body size of senior males is necessary which reflect their physical characteristics and activities.

In this study, the difference in the mechanical properties of silver and cotton weft knitted fabrics was studied. Six silver fabrics for the summer ladies' knit outwear were knitted varying knit structure and fabric density. Two commercial cotton knitted fabrics were selected to compare the properties. subjective sensation of hand of the fabrics was also studied. Mechanical properties of the fabric samples were measured by KES-FB system. From these, primary hand values(HV) were evaluated by the conversion equation (KW-403-KTU) and the total hand value(THV) was carried out according to the KW-304 Summer. The result of the research show that silver weft knitted fabrics had lower LT, RT, G, 2HG and higher EM, W, LC, WC, RC than cotton weft knitted fabrics. The use of silver yam contributed to increase in surface roughness of knitted fabrics. As the silver knitted fabrics became thicker compressional energy increased. The use of silver yarns contributed to much better fabric handle compared with the use of cotton yam only. It appeared that coefficient of friction of tuck stitch was larger than that of plain and interlock stitch. KOSHI and FUKURAMI values of the tuck samples were significantly higher than those values of the plain and interlock samples, while SHARI values were low in general. The total hand value of tuck stitch was higher than those of interlock and plain stitch.

The Purpose of the study was to examine the formative characteristics of silver fashion design by analyzing the silhouettes, colors, patterns, textures, and details in the brands for silver generation in Korea. Photographs of silver generation women's brands were collected to be analyzed with a focus on formative characteristics using SPSS packages. The result revealed the common formative characteristics of madam-brands and designer boutique brands-they both use semi-fitted silhouette with lighter colors for upper garment, and darker shades for lower garment. When it come to textile, upper garment was mainly made with hard and soft textile. In patterns, plain, flower print, and asymmetrical patterns were used for upper garment, and plain patterns for lower garment. Despite the gap in price, there were few differences in madam-brands and designer boutique brands with partial differences in the kinds of patterns, the proportion of patterns, the details such as zip-ups and buttons, beads, laces, and ruffles, and the use of different textiles for each brand. In conclusion, it is important to develop design that helps cover the body shapes of silver generation customers while highlighting the unique design of each brand for the development of the silver fashion.

This study provides improved wrinkle recovery and UV protection capabilities as well as an antibacterial and deodorizing function to linen fabrics for summer shirts. The results obtained from this study are as follows. By setting catalyst concentration to 1.2% and DMDHEU concentration to 6% respectively and applying a heat treatment to them at $160^{\circ}C$ for 5 minutes, the decrease of fabric strength could be minimized and the crease resistance of linen fabrics improved. Compared to the treatment with DMDHEU only, the crease resistance of linen fabrics could be maintained and degradation of their properties could be more effectively prevented by applying the mixture of the UV absorber and the nano silver to the DMDHEU resin. The UV protection of fabrics could be improved by adding the UV absorber. Although the separate treatment of resin or the nano silver had no effect on the improvement of the UV protection properties for treated fabrics, they could increase the UV protection capability when they were combined with the UV absorber. Linen fabrics could possess an antibiosis and deodorizing capability by applying the mixture of the UV absorber, the nano silver, and the resin. The UV protection, crease resistance and flexibility of finished fabrics were maintained even after laundering. Washed treated fabrics maintained excellent antibiosis and odor free capabilities compared to untreated fabrics.
