This machine is suitable for testing the elastic fabric in two ways (anyone value, given the length of) the role of recovery properties.
Woking principle:
Anyone Value: The upper end of the sample holder within certain specifications on the fixture, hanging below a certain weight weight loading four times the performance of load response after the test sample.
Fixed length method: A sample of a certain size upper and lower ends, respectively, clamped in the jig up and down, moving the specimen clamp stretched under a certain length of time to maintain a certain measurement sample recovery properties.
