Product description:
This machine is suitable for testing the elastic recovery performance of fabrics under the action of two methods (fixed force value, fixed length).
Features: Small footprint, large test volume, almost meeting all elastic recovery test standards.
Working principle:
Constant force value method: The upper end of the sample of a certain specification is clamped in the upper fixture, and a weight of a certain weight is hung below to load it for 4 times to test the recovery performance of the sample.
Fixed length method: clamp the upper and lower ends of the sample of a certain specification in the upper and lower clamps, move the lower clamp to stretch the sample to a certain length and hold it for a certain period of time to measure the recovery performance of the sample.
Accessories: Triangular hanger, 1 set of weights 3LB, 4LB and 5LB each (the quantity and weight can be selected according to customer requirements).
According to the standard: ASTM D3107
