  • Moisture transfer property of fabrics has known as one of the most important factors deciding wearer's subjective comfort not only thermally but also of sensorial. As a decisive property of fabric materials in determining human sensorial comfort, moisture vapor management property of heat resistant workwear material was examined in terms of increasing and decreasing rate and maximum value of relative humidity in the microclimate under the sweat pulse situation. An unique moisture regulation index, B$_{d}$, was calculated from the measurements using a novel dynamic sweating hot plate apparatus and was used to assess the buffering capacity of fabrics against a moisture vapor sweat pulse.e.

  • 옥타데칸[$CH_3$[C $H_2$]$_{l6}$$CH_3$]은 상전이 물질(phase change material)이며, 상전이 물질은 상변화를 통해 주변의 온도가 상승하면 녹으면서 열을 흡수하고, 주변의 온도가 낮아지면 결정화(crystallization)하면서 열을 방출하는 축열ㆍ방열성을 반복적으로 나타내는 에너지 물질(enthalpic substance)이다[1, 2]. 옥타데칸은 메탄계열 탄화수소로서 파라핀류(paraffins)에 해당된다. (중략)략)

  • As important factors determining human sensorial comfort, liquid moisture management and surface properties of heat resistant workwear materials were examined. To figure out liquid moisture management properties of the test materials, absorption capacity, rate of absorption, and evaporation properties were assessed. A modified GATS(Gravimetric Absorbency Testing System) was used to measure the liquid moisture accumulation associated with the wicking of liquid moisture from sweating skin. The GATS procedure measures demand wettability of materials to take up liquid in a direction perpendicular to the fabric surface and it was modified to incorporate a special test cell and cover to assess absorption behavior in the presence of evaporation. Fabric stiffness, smoothness, number and the length of surface fibers, and an estimate of the contact area between the skin and fabric surface were measured to characterize the mechanical and surface properties of the test materials. Also an estimate of the force with which a fabric clings to moist skin was made using as wet-cling index.

  • PCM has the ability to change their state, these materials absorb energy during the heating process as a body contact and release energy during a reverse cooling process as phase change take place. Using the thermal energy storage of PCM which has a melting point 15 to $35^{circ}C$ is one of the most effective ideas for utilization in textile finish. In this study, microencapsulated PCM(MCPCM) were synthesized by sol-gel method using the octadecane(or nonadecane) as PCM and the silica as microcapsule materials. To develop smart temperature adaptable textile, coating process was applied to textile substrate using a composition included MCPCM.
