JOURNAL FREE ACCESSThe combination of a“non-sweaty waterproof” (NSWP) outer garment and an inner insulator jacket is a common mountaineering clothing system in winter. To examine the effect of this system on climers in a very low temperature, water vapor permeability and water absorbability of insulating materials (polyester, acrylic, cotton, wool fibers and down) were studied. A polyethylene film was used for a model of frozen NSWP. The experiment simulated an outer garment, an inner insulator and a body surface. The humidity and temperature between inner fabric spaces (garment-insulator, insulator-body surface) were monitored and weight gain of insulating materials were measured. In the case of insulating materials made of polyester or acrylic fibers, more frost formation inside polyethylene film and less weight gain of insulator were observed in comparison with the case of wool or down. In cotton fiber, they were middle. For this reason, the combination of a NSWP garment and insulator that aborbs less water is not recommendable in a very cold environment.View full abstractDownload PDF (587K) -

JOURNAL FREE ACCESSThe purposes of this study are to examine how are physical properties and handle of knitted fabrics for baby's undershirt changed by home laundering, and to find out the relationship between the change of fabric specimen due to repeated launderings only and the change of shirts due to repeated wearing/laundering cycles. The results are as follows:
(1) It was found that knitted fabrics became hard to stretch, shear stiffness increased and compressional energy decreased with increasing the number of home launderings. An approximately linear relationship was recognized between the change of the physical properties and the square root of the number of launderings, √N.
(2) An offset effect was recognized in bending and shear properties due to dimensional change by laundering.
(3) “KOSHI”, “HARI” and “SHARI” hand values increase and “FUKURAMI” hand value decreases with launderings.
(4) The change of physical properties and handle of shirt by laundering is smaller than that of fabric specimen. But the changes of shirt in tensile resilience, bending and shear histeresis are same as those of fabric specimen or slightly greater than those of fabric specimen. This might be attributed to wearing. The wearing effect of pile knitted fabric mixed with polyester fibers was recognized in compressional property.View full abstractDownload PDF (3237K)
