This paper describes a new model of an instrument for the direct measurement of the air p ermeability of fabrics. The air, which is drawn through the fabric by a given suction, is measured with orifice-type fiowmeters. The instrument is mounted in the top of a t able and a new clamping device is provided, which p ermit measurements to be made rapidly on any part of a large piece of cloth without cutting.
