Abstract
This paper presents mechanism of emission, total particulate generation and partial one from the person clothed in the clean room garment, because it is desirable in the super clean room that particulate generation above workdesks such as one of a head and arms of the person is minimized to protect products and it is necssary to clarify mechanism of emission to decrease particulate generation from the person. 1) Particulates occure mainly inside the garment when the body is rubbing on underwears and pressure dif-ferencial between outside and inside of the garment that generates with moving, forces the inside dirty air to emite to clean rooms. 2) Partial particulate generation from slits around a neck and wrists based on this mechanism is about a half of total one. 3) Total particulate generation is from 5×10^4 to 75×10^4 particle/min ・ person on particulate diameter larger than 0.1μm and it is different based on personal phisiqe build.
