ABSTRACT:
The apparatus for testing the characteristics of waterproofness and breathability of fabrics includes a demonstration unit, a base unit, and a fluid conduit and valve. The demonstration unit has a transparent wall and a support plate/gasket combination to retain and support the test fabric specimen. The flexible fluid conduit runs between the demonstration unit and the base unit, and a valve is positioned in the conduit. To test a fabric's waterproofness: the demonstration unit is assembled; the base unit is filled with water; the demonstration unit is placed lower than the base unit, and thus, water flows into the demonstration unit; and the demonstration unit is positioned to expose and view the fabric. To show the fabric's breathability: the demonstration unit, filled with water, is positioned higher than the base unit; the valve is opened causing the water to flow out of the demonstration unit; and air is drawn through a breathable fabric and is visible as bubbles rising from the fabric into the water contained in the demonstration unit.
