Cotton surgical gowns are used at many operating rooms. However, it is argued that the quality of cotton is critical for the emission of airborne particles and the bacterial permeability.We have studied the airborne particles and bacteria refered to the washing and sterilizing cycles up to 20 times. The results obtained are summarized as follows.1. The airborne particles increased according to the cycle up to 10 times and reached a plateau level after that.2. The number of bacteria dispersed from cotton surgical gowns was correlated with the number of airborne bacteria of scrub attires (r=0.893,p<0.01). Also, that was correlated with the relative humidity and temperature of the operating room (r=0.791,p<0.01).3. Redudction rate of the airborne bacteria from cotton gowns increased depending on the number of the washing and sterilizing cycles up to 15 times and then reached a plateau level thereafter.4. The number of bacteria adhered on gown surface was decreased by the washing and sterilizing cycles.
