Fabric static tensile tester

The test principle of

Under the action of force, the fabric will produce stress relaxation and creep after a certain period of time. This instrument provides a device for loading stress, through the tensile stress test on the marked fabric, the deformation of the fabric is obtained.

Meets the following criteria:

ASTM D3107 ASTM D3107 test method for tensile properties of woven fabrics of elastic yarns -- test requirements for fabric tensile properties under specific tensile forces and for fabric creep under certain tensile forces.

Upper/lower clamping device: used for clamping samples, the lower clamping device is suspended in the test.

Weight: pull force of 1.35kg or 1.8kg together with the lower gripper.

Bottom tray: used for placing weight and lower clamping device, easy to operate.

Rotating wheel: make the test instrument movable, convenient for customers to arrange the space reasonably.

Overview of related test methods

This instrument can be used for the following tests:

Elongation of textiles under fixed tension: mark the dimensions on the fabric. A certain force is applied to the fabric sample under specified technical conditions to determine the distance between dimension marks under a certain tension. The fabric elongation is calculated by the distance between the marks before loading and the distance between the marks after loading.

Fabric growth after stress: make standard size mark on the fabric. A certain force is applied to the fabric sample under specified technical conditions. Remove the tension and measure the distance between the marks on the fabric sample after relaxation after a period of time. Fabric growth is calculated by the distance between the marks before stress and the distance between the marks after relaxation.

Elastic recovery: elastic recovery is the percentage of the elongation of the textile under fixed tension and/or the growth of the fabric corresponding to each time interval, relative to the length of the initial mark.

Sample preparation

According to relevant standards, three pairs of 65*560mm samples were taken, and the length direction was parallel to the test direction.

Remove approximately the same amount of yarn from both sides of the sample to a width of 50±1mm.

The specimen is folded 32mm away from one end of the specimen, and a suture line is sewed about 25mm away from the polyline.

Note: it is mentioned in the standard that a small cut is made in the middle of the polyline along the direction of the sample to insert a pin of a certain weight. Due to the optimized design of this instrument, the lower clamping device can directly grip the sample without opening. The following picture shows the lower clamping device and weight.

Mark the middle portion of the sample with a width of at least 250±1mm (along the test direction).

4.3 test -- constant tension

One end of the sample is fixed with a clamp so that the other end with crease is suspended freely.

Measure and record the distance between the markers, accurate to 1% or 1mm.

Hold the sample with a clamp and hang a certain weight.

After a certain time, take off the weight, measure the distance between the recording points again, and calculate the elastic elongation and elastic recovery rate of the fabric.
