What are the devices used to test the fabric strength?

The equipment used to test the strength of fabrics is often called a Universal testing machine. It is an instrument used to test the mechanical properties of materials, and can test the tensile, compression, bending, shearing and other properties of various materials.

When testing fabric strength, Universal testing machine usually uses tensile testing method. Tensile testing refers to placing a fabric sample between two clamps and then applying a tensile force to measure the deformation and failure of the fabric during stretching.

Before tensile testing can be performed, fabric samples need to be prepared. Usually, the size of the fabric sample is 100mm x 300mm, which needs to be cut into the corresponding shape and size according to the test requirements. Then, the fabric sample is clamped between two clamps, and the shape and size of the clamps also need to be selected according to the test requirements.

Before performing the tensile test, it is also necessary to set the test parameters. These parameters include test speed, preload, maximum load, etc. The test speed is usually 50mm/min, the preload is usually 10N, and the maximum load is selected according to the strength of the fabric.

When performing a weave tensile test, the Universal testing machine applies tension until the fabric sample deforms or fails. During the test, the Universal testing machine will measure the tensile force and deformation of the fabric, and calculate parameters such as the strength and elastic modulus of the fabric based on these data.

In addition to tensile testing, Universal testing machine can also perform other tests such as compression testing, bending testing, shear testing, etc. These tests can help evaluate the performance and quality of fabrics, and provide important reference data for fabric manufacturing and application.
