Fabric Down-Proof Impact Tester (Impact Method)

Introduction
The first sample is made of bags which built a certain quality of the down. The sample bag is placed on the slope, and the impact needle fixed to the movable plate is reciprocated with the movable plate, and the specimen is subjected to compression shock at the same time. Repeat the operation to a certain number of shocks to stop the test.
 
Applications
The instrument uses the impact method to determine the fabric anti-drilling performance, suitable for testing all kinds of down products, such as duvets, down jacket and so on.
The fabric to be measured is made into a cylindrical bag containing feathers, feathers or a mixture thereof.
The sample bag is placed on the slope, and the impact needle fixed to the movable plate is reciprocated with the movable plate, and the specimen is subjected to compression shock at the same time. Repeat the operation to a certain number of shocks to stop the test.
