  • This study investigated heat generation characteristics of knitted and woven intelligent garments made of ZrC imbedded yarns through thermal manikin measurement. These emotional and intelligent thermal characteristics by thermal manikin measurement were analysed and compared with light/thermal radiation experimental results. Surface temperature of ZrC imbedded woven and knitted fabrics by light/thermal radiation measurement was $4^{\circ}C$ and $2^{\circ}C$ higher than that of regular PET control fabrics, respectively. Clo value as heat generation characteristics of ZrC imbedded woven and knitted garments with light exposure was 0.14 and 0.08 higher than that of regular PET control garments, respectively. These results were attributed to the far-infrared thermal radiation from ZrC imbedded in the core part of the intelligent bi-component filament, which was verified by far-infrared emissive power ranged between $6{\mu}m$ and $20{\mu}m$ through FT-IR experiment and by inclusion of Zr through EDS ingredient analysis. However, compressibility of ZrC imbedded woven fabric was lower than that of regular PET one, and bending rigidity was higher than that of regular one, which resulted in a little stiff tactile hand property of ZrC imbedded fabric. We found that ZrC imbedded intelligent woven and knitted fabrics were applicable to the intelligent garment as a heat generation textile material by thermal manikin measurement.

  • The purpose of the study was to determine the effect of air velocity on the thermal resistance of wool ensembles. Three suits for men with different weaving structure and density were made with the same design and size for the study. In addition, Y-shirt, underwear, and socks were prepared for constructing the ensembles. Thermal insulation of air layer and 3 ensembles were measured by using thermal manikin in environmental chamber controlled at 2$0^{\circ}C$ and 65% RH with various air velocity. The results were as follows: 1. Thermal resistance of air layer was 0.079 m2.$^{\circ}C$/W with no air velocity(less than 0.2m/sec). 2. Thermal resistance of air layer decreased with increasing the air velocity rapidly. When the air velocity was 0.25 and 2.89 m/sec, the decreasing rate was 15% and 61%, respectively compared with no air velocity. 3. While there was little difference among the effective thermal insulation of 3 ensembles having different weaving structure and density with no air velocity, there was sharp difference among them when the air velocity increased. That is, the decreasing rate of effective thermal insulation of the ensemble which has higher air permeability was higher. 4. The decreasing rates of the effective thermal resistances of plain, twill and satin ensemble were 61, 54, and 49%, respectively when the air velocity was 2.89 m/sec which was a maximum air velocity in this study.

  • In estimating the thermal insulation effect (TIE) by an experiment of wearing clothes on human body, lack of reproducibility and each part of clothing insulation value have been pointed out. Therefore an electrically-heated manikin was used to study the effects of clothing materials and seasonal clothes on the thermal insulation value of KMFC. The manikin consisted of a black anodized copper skin formed to simulated the size and shape of a typical man (height 170 cm, body weight 60 kg). The manikin was instrumented with 17 skin thermistor in various locations on its body. We reached the conclusion below through the comparison of western style men's clothes and Korean women's folk clothes (KWFC), The TIE for KMFC is 0.63-0.84% for summer clothes and 1.28∼1.32 clo for spring and fall ones. For the total thermal resistance (1‥‥‥) when wearing KMFC, standing position has a bigger one than sitting position, and the change by each position is more than that of western style men's clothes. For the TIE of KMFC, that thermal resistance of the back part is more than that of western style men's clothes, which is a major factor causing bigger TIE. In addition, the weight per unit area of KMFC was highly positively correlated with the keeping warm.

  • This study evaluated the thermoregulatory properties of functional thermal underwear ('heating underwear') in markets using a thermal manikin and human wear trials. One ordinary thermal underwear (ORD) and two functional thermal underwear (HEAT1 and HEAT2; manufactured goods, HEAT1: moisture absorbing heat release mechanism, HEAT2: heat storage, release mechanism) were chosen. Thermo-physiological and subjective responses were evaluated at an air temperature of $5.0{\pm}0.5^{\circ}C$ and air humidity of $30{\pm}5%RH$ with five male subjects ($21.6{\pm}1.3yr$ in age, $178.0{\pm}5.9cm$ in height, $68.2{\pm}5.9kg$ in body mass). Experimental conditions consisted of four ensembles that included winter clothes (Control: no underwear, ORD, HEAT1, HEAT2). Water-vapor resistance was greater in fabric of HEAT1 than others. The results were: 1) Total thermal insulation (IT) using a thermal manikin were not greater for HEAT1 (0.860clo) and HEAT 2 (0.873clo) than for ORD (0.886clo). 2) There were no significant differences in rectal temperature, mean skin temperature, heart rate and total body mass loss between the four conditions. Microclimate clothing temperature on the back was greater for ORD than for HEAT1 and HEAT2. Subjects felt more comfortable with HEAT1 than for others at rest. HEAT2 was higher in microclimate humidity when compared to other conditions. The results suggest that thermoregulatory properties of 'heating underwear' in market did not differ from those of ordinary thermal underwear in terms of total thermal insulation and thermoregulatory responses in a cold environment.

  • This study was designed to develop air force mechanic parka, evaluate it, and ultimately provide functionally superior parka to the air force. The development process was 1) conducting a survey, 2) identifying problems and shortcomings of currently-supplied parkas, and 3) improving the design, pattern and materials. The newly-developed parkas were evaluated in terms of their ease of fit, clothing mobility, and insulation. Ease of fit was evaluated by subjects' sensory tests, and clothing mobility was by fitness-for-motion tests and range-of-motion tests using a Goniometer. Evaluation on insulation was conducted by thermal manikins. Findings of this study were as follows: 1. In the subjective evaluation on clothing mobility, new parkas were considered to have sufficient ease of fit while previous ones scored much lower, confirming the improvement of the new version. 2. Both subjective tests and ROM measurements on fitness for motion verified the superiority of the new parkas. 3. Insulation tests found that although insulation capability of newly-developed parkas was at a similar level to those of the previous ones, their insulation capability per unit weight was superior, demonstrating that new parkas were better at blocking heat conduction. When making changes in parka patterns and designs to enhance the mobility, it was necessary to maintain the insulation function. The new parkas developed by this study was verified to be superior to the previous ones in their insulation and clothing mobility.

  • The purpose of this study was to create a database of information on fabric factors(i.e., fabric insulation, fabric weight, clothing weight, fabric thickness, air permeability, and water vapor resistance) of clothing used for insulations, to compare them according to clothing types, and to estimate thermal resistance of clothing using these factors. A total of 25 kinds of clothing were selected(9 types for suits, 6 types of jacket, 5 types for shirts, and 5 types for trousers). The results of this study were as follows; Thermal insulation of clothing showed the highest positive correlation(0.85, p>0.01) with thermal insulation of fabric and very high positive correlation with water vapor resistance, fabric thickness, fabric weight, and clothing weight, respectively, 0.77, 0.77, 0.73, 0.71(p>0.01). Fabric weight of jacket was higher than that of shirts and trousers. Air permeability of shirts was the highest of clothing types. Clothing insulation of jacket was higher than that of shirts and trousers and its fabric insulation was also the highest of clothing types. Regression analysis showed that fabric thickness, water vapor resistance, and fabric weight would be useful factors for estimating the thermal resistance of clothing.
