Tensile tearing test devices are, like the other tensile devices, important quality control test device for many sectors.

Tensile Compression Devices also have the tearing test feature that is dealt with in this article. The tensile tearing test device is also specifically manufactured for other sectors. In this article, we present an example to help you familiarize with the Tensile Tearing Test Device and its importance.

For example, in textile industry, the performance of textile materials during their use depends in general on their behaviour when subjected to forces. This is why, to determine and analyse their behaviour manufacturers need strength tests.

Tearing strength test is one of the most informative strength tests about the strength of fabrics during their manufacturing processes and their use. The most accurate results come from Tensile Tearing Test Devices. Manufacturers use Tensile Tearing Test Devices to measure the strength of their products in order to correctly design their production.

The tearing strength is the strength against the starting, continuation or spread of a tearing under given conditions. The tearing strength is an important factor that determines the material’s strength against the static and dynamic forces in the fabric and against the strain applied during the tearing test.

During the tearing, yarns break individually or in group.

This is why the strength of individual yarns is important. Furthermore, the construction of the fabric and the processing operations applied to the fabric are other factors that affect strength. In strength measurements other than the ballistic pendulum method, devices used for fabrics’ breaking strength can be used. Usually, CRE-type tensile test devices with a constant sample elongation rate issuing force-elongation graphics are used. The tearing strength test is conducted with at least 5 samples separately on the direction of warp and weft. For samples whose length is parallel with warp, the direction of tearing is defined on the basis of the “weft length” and for samples whose long side is parallel with the weft the tearing is defined on the basis of the “warp” length.

Different standards are used for the tearing strength.
