This study was performed to define the effects of Far Infrared Ray Radiation Fabrics as summer garments during outdoor work by human trial. One healthy male subject was volunteered for this study. Experimental garments consisted of three kinds of trousers (Cotton, Cotton/linen blended, Far Infrared Ray Radiation Fabric/wool blended) and basic garments (panty, socks, shirts, and dress shirts). The measurements were rectal temp., skin temp., microclimate inside clothing, heart rate, subjective sensation etc. The results were as follows : 1. Rectal temperature showed the lowest in Far Infrared Ray Radiation Fabrics among 3 garments. 2. Skin temperature (forehead, chest abdomen temp.) and mean skin temperature were lower in Far Infrared Ray Radiation Fabrics than in others, especially during early stage of work. 3. Heart rate showed lower value in Far Infrared Ray Radiation Fabrics than in others but there was no significance among the garments. 4. Humidity inside clothing and total weight loss showed the highest value in Far Infrared Ray Radiation Fabrics.

To develope a high value-added fiber products which is useful in the human body physiology, the Macban stone was deposited on the PET fabric by sputtering and its effects were investigated. Then, a Macban stone target was prepared for sputtering treatment and treated on the PET fabric by RF sputtering process. After treatment, surface observation by SEM, far-infrared emissivity and emissive power, the fastness to washing and light, bacteriostatic rate, electrostatic, drape stiffness, and breaking strength of PET fabric were investigated. From these investigation, the following conclusions were obtained. 1) The Macban stone was able to deposit on the PET fabric, by the RF sputtering treatment which is eco-friendly dry textile finishing. 2) The far-infrared emissivity and emissive power of sputtered PET fabrics were increased. 3) When PET fabric was treated by sputtering with Macban stone, the amount of deposited Macban stone increased with increasing treatment time and it was deposited on the fabric surface firmly. 4) The bacteriostatic rate of sputtered PET fabrics was about 20%. 5) The electrostatic charge of fiber surface was reduced by sputtering. 6) The fastness washing to light of dyed fabric were improved by the deposition of Macban stone, but the breaking strength was not changed by sputtering. 7) The drape stiffness of sputtered PET fabrics increased with increasing treatment time.

This paper investigated wear comfort property of heat storage knitted fabrics for high emotional garment. For this purpose, ZrC imbedded PET knitted fabric was prepared and various physical properties such as thermal, wicking and drying characteristics were measured. In addition, far-infrared emission characteristics of ZrC imbedded PET was analysed and tactile hand property and dye affinity of ZrC imbedded knitted fabric were also studied in comparison with regular and other commercial heat storage PET knitted fabrics. It was observed that Zr imbedded amount in the yarn was 19.29% by ingredient analysis and far-infrared emission energy was $3.65{\times}10^2W/m^2$, emissivity was 0.906 at the range of wavelength $6{\sim}20{\mu}m$. It was found that maximum heat flow (Qmax) of ZrC imbedded PET knitted fabric was lower than that of regular PET one and warmth keepability rate was higher than that of regular PET one, which means ZrC imbedded PET have heat storage property. Drying property of ZrC imbedded knitted fabric was better than that of regular PET one due to heat by far-infrared emitted from ZrC in the core of filament. It revealed that wicking property of the ZrC imbedded fabric was not influenced by far-infrared emission, but affected by fibre physical properties. Tactile hand property of ZrC imbedded knitted fabric was not influenced by imbedding ZrC in the filament but affected preferably by structure of knitted fabric. Dye affinity of ZrC imbedded PET knitted fabric was less influenced by dyeing temperature and time than regular PET knitted one.

In this research, the curly dock was used in the process of dyeing for fabrics of the inner wear & the patient wear. Since the curly dock has a pharmacological effect on dermatosis, this study focused on the variety of color and functions of the inner wear fabrics & patient wear fabrics to make the best use of the pharmacological effect of curly dock. With regards to giving a variety of colors and functions in the inner wear, patient wear fabrics, the curly dock dye was used in each treatment conditions on the cotton & silk fabrics. After dyeing, the dyeability, color change, light fastness, washing fastness, perspiration fastness, antibiosis, far infrared emissivity and emission power were evaluated. The evaluation results are as follows; The dyeablity increased from repeated dyeing and, by using the mordant, variety of colors such as skin, mustard, greyish-brown and dark earth colors were conformed to the naked eye. Fe mordant was better than Al on the lightfastness and the washing fastness. The repeated dyeing was found out to have less effect on neither lightfastness nor washing fastness. Both silk and cotton fabrics were graded $3{\sim}4$, since their degree of degradation appeared to be the same in alkali perspiration and acidic perspiration. In the case of silk fabrics mordanted by Al, the rate of declining in both Staphylococcus aureus ATCC 6538 and Klebsiella pneumonia ATCC 4352 were 99.9%. In addition, the antibiosis was enhanced when the mordant was used. The far infrared was 86.6% of emissivity, $3.34{\times}10^2\;W/m^2{\cdot}{\mu}m$ emission power.

For the application of Jeju scoria scattered around the island as a natural dye, cotton fabrics were dyed with the dye and their properties were measured including dyeability, colorfastness, antibacterial activity, deodorization efficiency, ultraviolet protection, and far-infrared emission. The dyed cotton fabrics were in yellowish red and optimal dyeing conditions were obtained with a colorant concentration of 25%(o.w.b) at a temperature of $80^{\circ}C$ for the dyeing time of 120 minutes. The ratings of colorfastness to light, rubbing, perspiration, and washing were 8, 5, 5, and 4~5 respectively. After 15 wash cycles, colorfastness remained as much as 4~5 rating. The cotton fabric dyed with Jeju scoria demonstrated excellent antimicrobial activity and deodorization efficiency of 99.9% and 93.9% respectively. Ultraviolet protection factor was 50+. Far-infrared emission rate and far-infrared emission intensity were 90% and 362(W/$m^2{\cdot}{\mu}m$) respectively. The Jeju scoria can be introduced as a new colorant for the natural dyeing of cotton.

본 연구는 감성의류용 탄화지르코늄 함유 축열 니트의 원적외선 특성을 연구하였다. 탄화지르코늄 함유 축열 PET 원사가 이성분 방사법에 의해 방사되었다. 이 원사의 core부에는 고점도 PET와 탄화지르코늄을 혼합한 용액을, sheath부에는 저점도 PET 용액을 사용하여 콘쥬게이트 방사를 실시하였다. 이들 방사된 원사의 원소분석과 원적외선 특성 분석이 EDS와 FT-IR 계측기기에 의해 분석되었으며 두 가지 조직의 니트 소재를 편직하여 이들의 열적특성을 분석하였다. EDS 분석에서 Zr 피크를 확인하였으며 원사내에 Zr 원소가 19.29% 함유되어 있음을 확인하였다. 또한 원적외선 분석에서 $5{\sim}20{\mu}m$ 파장 영역에서 원적외선 방사에너지가 $3.65{\times}10^2W/m^2$, 방사율이 0.906 임을 확인하였다. KES-F7 측정기 분석에서 ZrC 함유 편성물의 Qmax 값이 일반 PET 편성물의 값보다 낮은 값을 보였고 보온율 값은 ZrC 함유 편성물이 일반 PET보다 더 높은 값을 보이므로서 ZrC의 축열성을 확인하였다. 열전도도는 Zr의 높은 열전도도 때문에 일반 PET 편물보다 더 높은 값을 보였다. ZrC의 함유가 편물의 촉감에 미치는 영향을 없었으며 편성 조직이 더 큰 영향을 주는 것을 확인하였다.

In order to activate the characteristics of charcoal in fiber systems, this was carried out to experiment with the particle size from two micrometers to ten micrometers of charcoal powders on cotton fabrics. The results obtained were as follows; The fabrics were dyed with gray colors by charcoal. The K/S values, that were indicative of the dye affinity, became higher as the increase of dyeing temperature, dyeing time, and dyeing concentration. Also it was confirmed the morphology of the fiber surfaces adsorbed with the particle size from two micrometers to four micrometers of charcoal powder by scanning electronmicronscope. The cotton fabrics dyed by charcoals generally recorded 3-4 degree of wash fastness, 4-5 degree of dry-cleaning fastness, 4-5 degree acidic and alkaline perspirations and water fastness. In connection with the functional properties, cotton fabrics dyed with charcoal appeared that antibacterial, deodorization, far infrared emissivity were improved. Especially the deodorization was improved greatly by using charcoal.
