Everyday we encounter countless textile components such as straps on bags, buttons, or toys made of textiles. They are subject to constant loading and must fulfill certain quality characteristics to be able to meet safety criteria reliably (for example, buttons, straps, belt connectors). The reproduction of real-world conditions sometimes requires complex test arrangements, different specimen grips, and reliable results. ZwickRoell offers a wide-ranging product portfolio to cover a large variety of tasks.
BS 3084 shows the different types of zippers and a variety of test options.
In this example, a plastic zipper is tested to determine its properties. The textile part of the zipper is clamped so that the zipper is supported.
A tensile test is carried out perpendicular to the zipper and tested until the zipper fails. The maximum force is determined and the results are shown in a typical force travel diagram.
Belt connectors in the form of loops, knots or clips are tested for their safety-related properties.
In the example shown, the maximum force that affects the stitching, the safety clip, or the belt is determined. The belt is rolled in the roller grip and is held securely; on the opposite side the bracket is clamped in a pneumatic specimen grip.
The tensile test is carried out according to DIN EN 1492 to determine the maximum force of the entire connection.
Universal testing applications in a small force range up to 5kN. Tensile test, Compression test, Flexure test etc.
Two steel columns provide highly accurate guidance for ProLine’s moving crosshead. The stiff load-frame profile and generous connecting surfaces reduce the inclination angle of the crosshead under load, enabling very precise alignment and application of force to the specimen.
The AllroundLine is our customizable and extremely versatile testing machine. It is available as a floor-standing testing machine and as a table-top testing machine.
