The purpose of this study was to evaluate thermal comfort properties of surgical gowns made of dual functional finish cotton and nonwoven fabrics which have barrier properties of blood and micro-organism. Four types of surgical gowns, which were made of nonwoven fabrics with finish or without and were made of cotton with finish or without, were tested. The thermal insulations of four surgical gowns were measured with thermal manikin. Subjective experiments on thermal comfort, skin temperature and clothing microclimate were conducted. Six male subjects, between 26 and 28 years age old, participated in the wear trials tests. Typical activities for surgeons in the operation theater were simulated during the experimental sessions. Air temperature in a climate chamber was kept at 22 degrees C and its humidity was 60% RH. Air velocity was controlled at less than 0.15 m/s. Inner radiant temperature was almost equal to the air temperature. Basic thermal insulation of the dual functional finished nonwoven surgical gown was 0.87 clo, which was slightly higher than that of untreated (0.84 clo). However, the skin temperature of the subject wearing a dual functional finished surgical gown was significantly lower at P < .05. When the subject wears the dual functional finished gown, the amount of sweating was less than that when wearing untreated. Microclimate temperature and humidity of dual functional finished surgical gown were lower than untreated and it was statistically significant. There was no significant difference in subjective humid and overall comfort sensation between finished and untreated ones. Thermal sensation of dual functional finished one was significantly different from untreated one only during the first exercise. The results of this study indicate that the dual functional finish surgical gown allowed heat to be transferred from the skin of subject to the atmosphere better than untreated. The nonwoven surgical gown showed no difference in comfort properties from cotton one.
