The purpose of this study was to clarify the fabric characteristics of the rush material blouse in response to human thermal responses and its amenity during the heat loading in women. As comparison of the rush material, the clothes of 3 kinds materials (rush20% pulse cotton80%, cotton100% and nude) were used in the present experiment. The eleven females were exposed by 43-degree water heat loading for 30 min and a 30-min recovery. Individual skin temperatures, local sweat rate, body temperature, and in-clothes temperature-humidity were measured throughout the experiment. Although the mean skin temperature (T ̅sk) under rush blouse was abrupt increased at early heart loading, it tended to be lower than under cotton100% blouse. During recovery period, both T ̅sk and core temperature (Tcore) under the rush blouse decreased slowly compared with cotton100% and became significant at later of recovery (p<0.05). The increases of inner-clothe temperature and humidity were significantly higher in the rush blouse than in cotton blouse, suggested that would be attributed to the material property of heat retaining. In addition, thermal sensation, wet sensation, and comfort sensation in the subjective evaluation mostly corresponded to some skin temperatures in regions of back, forearm, sweating rate, and in-cloth temperature and/or humidity. These findings suggest the rush material suppresses the change of microclimate within clothing during the thermal stress in human, would be expected the application as winter shirt in elderly or the garment for the mountain climbing.
