초록

In this study, in order to manufacture a composite yarn with excellent flameretardancy and resistance to external loads, a composite yarn was prepared by mixing oxi-PAN fiber and para-aramid fiber, and then the composite yarn and FR (flame resistance)rayon fiber were used. fabrics were woven, and the optimal weaving conditions wereselected by analyzing the thermal and physical characteristics according to the weavingconditions. A hot-melt type adhesive was used to adhere aluminum-coated polyethyleneterephthalate (PET) to the surface of the woven fabric, and the radiant heat protection performanceand heat resistance characteristics were analyzed according to the type of adhesive.
Based on the physical property DB (in-put data) of the manufactured heat-dissipatingfabric, heat-resistance performance prediction simulation was conducted when the heatdissipatingfabric was worn and when it was not worn. As a result of predicting the temperaturechange on the surface of the human body when the external heat load is 250oCand the heat exposure time is 8 seconds, when wearing heat radiation clothing, the humanbody surface temperature is reduced by up to 8.6%. As a result of correlation analysisbetween the simulation result and the actual test, it was confirmed that the temperaturechange in the actual experiment was 38.9oC, which differed by 1.2% from the simulationresult.
