Down-proof Tester, to determine the down-proof capability of fabrics used for down-garment, quilt, etc, which are filled with down, feather and fibers.
Take an agreed size specimen from the fabric to be tested to sew a pocket at specified size, fill with a certain weight of down, feathers or a mixture of both, then sew the fabric up to be a testing bag. Clamp the both sides of the bag in the holder. Determine the down-proof ability of the fabric by calculating the number of down and feathers through the fabric.
