Apparatus and method for testing air permeability of a fabric

摘要

An apparatus and a method for testing permeability of a clean room garment material are described. The apparatus is constructed by a flow regulator, a flow meter, a sample holder and a quantitative tube that is equipped with a fluid reservoir for generating a bubble through the tube. The components of the apparatus can be readily obtained and the apparatus can be constructed at low cost. The method for testing air permeability can be conducted easily by utilizing the present invention novel apparatus in a factory environment without elaborate and expensive equipment.
