Downproof Tester, To determine the downproof capability of fabric used for downgarmet, quilt etc, which are full 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. After test to determine the downproof ability of the fabric by calculating the number of down and feathers through the fabric

The Definition of Fabric Down-proof Capability
The fabric down-proof tester is used to detect the ability of down or fiber to drill through cold clothing, bedding and so on. Down-proof property refers to the fabric's ability to prevent down or feather from leaking through the yarn crevice, expressed by the drill number under specified conditions.
At present, there are three testing methods of fabric down-proof property at home and abroad: the rotating box method, the friction method, and the impact method. The basic principles are to simulate the external force in the actual wear process of down products, make the feather down drill out of the fabric surface through the functions of extrusion, kneading, and friction, etc. Evaluate the fabric's down-proof properties by calculating the number of drill roots.
The friction method is to make the sample into a sample bag of a certain size and put in a certain quality feather down filler. Install the sample in the plastic bag of the instrument, and make the feather down drill out of the fabric surface through the functions of extrusion, kneading, and friction, etc. Evaluate the fabric's down-proof properties by calculating the number of drill roots.
1 Cut the sample as required. Adjust the sample in an atmosphere according to EN 20139, and measure the temperature and relative humidity according to EN 20187.
2 Before testing, the cushion is placed in the plastic bag. This permits total collection of any particles that penetrate completely through the cushion's primary tick fabric.
3 The plastic bag containing the test cushion is then fastened in the clamps of the test apparatus. The cushion's flaps are placed in the clamps and the cushion is folded between these clamps.
4 The counter is set for 2700 revolutions. The apparatus is started, and after 2700 revolutions (approximately 20 min) it is automatically stopped by the counter.
5 Afterward, the cushion is taken out of the plastic bag. If the number of filling particles in the plastic bag plus the number of filling particles protruding from the cushion is greater than 50, counting shall be stopped.
