| Research Abstract |
The purpose of this study is to obtain basic data for designing quilt fabrics from the point of the comfortable characteristics which are considered to have much meaning in end use. Although the thermal transmittance and moisture and air permeation through a quilt fabric were estimated by the conventional methods, T-HPermeability Tester which was possible to estimate the characteristics in the coexistence condition of heat and moisture was used also.
The thermal insulation ratio by the ASTM thermal transmittance test increased with the increases of the number of polyester non-woven fabrics (wadding ) and the spacing between stitched seam lines but the moisture permeation estimated by the cup method had a tendency to change inversely to the thermal insulation ratio. Both the thermal insulation and moisture permeation ratios were equated using the average thickness of quilt fabrics. The airpermeability of quilt fabrics did not always have the same ten-dency toward the moisture permeability. The air permeation wasequated using the packing ratio of quilt fabrics. Unlike thethermal transmittance, the moisture and air permeability was largely effected by the characteristics of outer fabrics. The results obtained by T-H Permeability Tester showed the same tendency toward the results of the conventional methods although there was a large gap. It was considered that T-H Permeability Tester evaluated thermal insulation ratio including the latent heat and it caused the gap. As forthe insulation ratio and the amount of moisture permeation, the results also could be equated using the average thickness. The useful data for designing quilt fabrics were obtained from the results mentioned above.
