ASTM D3939 ICI Hammer Type Fabric Snagging Tester with 4 Work Stations
Brief introduction:
It can quickly detect how easy it is for the fabric to hook under normal wearing conditions (i.e. the yarn is hooked out of the fabric).
Principle:
The cylindric sample is covered on the rotating cylinder, and the chain hanging hammer is placed on the surface of the sample.When the cylinder rotates at a constant speed, the hammer randomly turns and jumps on the surface of the sample, and hooks the sample to produce hooks on the surface of the sample.After a specified number of revolutions, the sample's hook degree is rated by comparing with the standard sample.
Applicable standard: GB/T 11047 ASTM D3939 JISL1058
