The purpose of this study was 1) to determine physical properties, and subjective evaluation of sensation of sports socks with various type of fiber content and fabric structure, and 2) to develop regression equations for predicting each sensation from physical properties of socks. Thirty healthy male students participated in the wear test with ten replications. The ANOVA, Duncans multiple test, and multiple regression, and paired-t test were used in the statistical analysis, using an SAS package. The results of this study are as follows: 1. 100% cotton socks had higher absorbency and wickability among five different socks. Comfort sensation, tactile sensation and fit sensation of socks were significantly influenced by types of fiber content. People felt that polypropylene socks were less comfortable & slightly tighter, and cotton socks were drier than the other socks. Terry socks were warmer than single jersey socks. 2. The results of the regression analysis showed that tactile sensation of socks after exercise can be predicted from the cube of moisture permeability($R^2$=0.99), and fit sensation can be predicted from drop absorbency, moisture permeability, wickability in wale and weight($R^2$=-0.98).

The purpose of this study is to investigate hand and sensibility of PET treated by Ultra-Violet (UV). The 4-channel PET knit fabric was treated by a self-made UV instrument in 5cm distance with different time frames-0min, 30min, and 90min. For hand evaluation, mechanical properties were measured by the KES-FB system. The environmental condition was controlled at 29$^{\circ}C$, 75% (R.H.)-summer standard climate. Twenty female students evaluated 'roughness', 'smoothness', 'wetness', 'stiffness', 'coolness', 'touch', 'preference', and 'comfort'. The outcomes of the experiment are as follows: The surface roughness of mechanical properties showed significant differences and the value of PET irradiated by UV for 90min was highest. The order of primary hand value such as NUMERI and FUKURAMI was in a following order-Untreated > 30min treated > 90min treated. Total hand value showed that PET irradiated by UV for 90min was appropriate for using summer fabric. The results of subjective sensibility were that the untreated and 30min treated PET were recognized as similar and had a good evaluation on 'comfort', 'preference' and 'the sense of touch'. This consequence disagreed with total hand value, because it was considered that subjects' hand sensibility was dependent on the feel of smoothness.

This study examined several dyeing properties, physiological responses and comfort sensation of cotton knit underwear dyed with bamboo charcoal. The cotton knit underwear dyed with bamboo charcoal and treated with chitosan showed 99.9% antibacterial property and improved deodorization, and colorfastness. Eight children with atopic dermatitis worn underwear dyed with bamboo charcoal during 4 months. Their parents reported fewer itches of children. Wearing cotton knit underwear dyed with bamboo charcoal and non-dyed with bamboo charcoal respectively, these eight children rested for 20 minutes, then exercised for 10 minutes, and then rested for 30 minutes in the room maintained $28{\pm}1^{\circ}C$ and $50{\pm}5%R.H.$ Children's rectal temperature, skin temperature and microclimate inside garment of two types of cotton knit underwear were compared. As a result, the rectal temperature and skin temperature were higher when children were wearing underwear dyed with bamboo charcoal than non-dyed underwear. The microclimate temperature and microclimate humidity at the back of children were lower when children with underwear dyed with bamboo charcoal exercised and recovered.

Studying awareness, importance, satisfaction, and wearing behavior of functional textiles for active silver generation related with gender and age is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, silver generation considered all the clothing comfort sensations important when wearing clothes, such as tactile sensation, clothing pressure sensation, thermal/wet sensation, and motion sensation in human physiological aspect. Also, stretchy fabrics were ranked first in awareness, the number of wearing times, and satisfaction of comfort functional fabrics. More than 30% of silver generation have fifteen items out of 36 functional clothes. Second, in analysis of awareness by gender on functional clothing products, women were more aware of health/safety-oriented fabrics than men were. Otherwise, men had more knowledge about the water-related properties of functional fabrics than women have, such as water/moisture absorptive and water-repellent/vapor permeable fabrics. While women have more indoor casual wear, men had more active sportswear. Also, women expressed a strong preference to the stretchy function of fabrics.

This study was executed to show influence of material and property of sportswear to physiological responses of body and comfort sensation and to supply basic research data about comfortable sportswear Trainning wear was manufactured with cotton(C) and hygroscopically treated polyester material (FP), and its properties of material were measured. Then rectal temperature, skin temperature, heart rate, weight loss, clothing microclimate and subjective sensation was estimated with study of wearing with these sportswear and examined the influence that it got to physiological responses of body and sensation. Health adult men were selected for subjects and executed at climatic chamber of temperature, $20\pm2^{\circ}C and humidity, $60\pm5%$ R.H. Conclusively sportswear of hygroscopically treated polyester is a favorable functional material. So far factor that affect to physiological comfort sensation has been explained mostly by moisture regain but in our experiment, it turned out that air permeability, water absorption velocity and dynamic oater absorption etc. were affecting factors. So according to this result, air permeability and moisture permeability should be considered with transmittance of temperature moisture for development of comfort material.

The paper discusses the potential of nanomaterials in revolutionizing basketball equipment by applying them to advance padding and shock absorption technologies in order to bring more control and comfort to the players. Nanotechnology devised new solutions for the challenges that the players are exposed to by dealing with issues such as better control reducing shock to the hands and wrists during those most decisive periods of every game: dribbling, passing, and catching. This work embeds nanomaterials in basketballs to understand their efficacy in reducing the amount of force transmitted to players, thereby reducing the risk of injuries and fatigue. The research gives an in-depth look into the structural properties and performance benefits of nanomaterial-enhanced padding in balls for optimized comfort and control to players and improvement in the dynamics of gameplay. The future of nanotechnology in the design of basketball equipment finds further bases in an in-depth analysis and is experimentally validated with respect to the prospects of a ball that is safer, long-lasting, and with improved performance.

The purpose of this study was to investigate mechanical and comfort performances of the material for the improved working uniform for a volunteer fire brigade member, to get basic data for its evaluation and to help its material and design development. The results were as follows; The material of the newly developed working uniform was thinner and lighter than the material of the current used working uniform. It had better breathability, air permeability and heat transmission rate than the current one. It also had superior anti-flammability In all mechanical properties(tensile, bending, shearing, compression and surface properties), it showed better performances than the current one. It elongated and bended easier and more in both warp and weft directions. The elastic recovery and shape stability after elongation were also higher. The recovery and resistance to shearing and the resiliency and recovery after compression were also better than the current one. It was more flexible, softer and smoother in primary hand value, and was more suitable for the material for winter suit which needs softness and fullness in total hand value. The material of the improved working uniform showed lower thermal insulation value and higher evaporative resistance value compared to the material of the currently used working uniform from the sweating thermal manikin test. It was shown that the physical performances and the hand value of the textile material used in the newly developed working uniform for a volunteer fiber brigade member was improved compared to the one used in the currently used working uniform.

Heat conductivity, height, size, elasticity of pillow, stability of shape, hygroscopicity, ventilation, temperature and easy movability, and so on, are considered to be some of major conditions that affect the comfortable sleep. Considering those factors together, the thermal properties, height, shape and feeling of touch, etc, of pillow must be taken into account. Though studies have been conducted to figure out the physical properties of mattress or pillows from the perspective of factors related to the environment of sleep, they are not enough to be used as an index to evaluate the qualitative aspect of sleep. This study tries to consider the effect of pillow filling materials on the comfortable sleep, for which EEG, ECG, EOG, EMG, RT, etc, are to be measured in an attempt to provide the basic data required in proposing the condition that may lead to a sound and comfortable sleep. Three types of pillows that are sold in the market were used for this research in order to evaluate the quality of sleep depending on the filling materials of pillow. All data were statistically processed and the following conclusions were drawn. It was found that the pillow with feathers provided the best comfort as the pillow A turned out to have the shortest sleeping latency(SL) from the perspective of comfort. The pillow B which used the polyethylene is deemed to be suitable for fatigue relieving purpose as it turned out to have the highest slow wave sleep(SWS), but no statistically significant difference was validated. Moreover, the pillow C which used the natural wool was found to have the narrowest contacting area of the pillow and head and provide a great warm heat comfort that may led to a sound sleep because the temperature below the pillow took the longest time to rise.
