An Apparatus for the Measurement of the Water-Vapour Permeability of Textiles.

Abstract

An apparatus has been constructed to measure the water vapour resistance of textiles, in particular those such as battings and piles that are highly air permeable and have low vapour resistances. The technique has been tested by measuring the water vapour resistance of air gaps in the range 1 to 8 mm thickness. No systematic errors were observed with a random error in the resistance measurement equivalent to 0.5 mm of still air. (Author)
