Lawson-Hemphill is releasing its two upgraded innovative solutions to textile quality assurance, ‘New Textile Burst Tester’ and ‘New Textile Tear Tester’ series.The textile burst tester is used as a multidirectional tensile test to identify failure in the direction of least resistance for evaluating the materials physical strength and fibre bond and the comparative strength of alternative fibres.
The instrument is designed for measuring the bursting strength of sample materials subjected to an increasing hydrostatic pressure. When pressure is applied, the specimen deforms together with the diaphragm. The bursting strength corresponds to the maximum pressure supported by the specimen before failure.
On the other hand, the latest addition in tearing testers offer a combination of technological integration and user comfort unique to this type of instrument that measures the force required to continue the tearing of an initial cut in textile materials.
Also known as the Elmendorf test, the tearing test has been performed in the textile industry for more than half a century in order to measure the mean internal resistance of textiles to the propagation of a deliberately initiated tear.
It enables rapid determination of the dynamic resistance of materials designed to be subjected to strong shearing loads (e.g. suitcases, industrial fabrics) or liable to be damaged by sharp or heavy objects (e.g. seatbelts, outerwear, protective clothing).
Subsequently, the test was naturally adopted for all materials in the form of cloth, knitted fabrics, nylons, industrial fabrics, non-woven fabrics, etc., for which the service requirements are required to sustain high tolerance.
