Zwick USA will be demonstrating its industry-leading textile materials testing solutions at the Techtextil North America Exhibition held here from March 19-21 at the Hilton Anaheim.
Zwick will display a wide range of materials testing capabilities that are supportive of applications in technical fabrics, yarns, fibers, plastics, films and composites, said Erik Wittenzellner, Application Engineer for Zwick USA, Kennesaw, GA.
Among the Zwick equipment on display will be a zwicki-Line system performing tensile and cyclic tests on fine denier filaments utilizing specialized screw grips as well as on threads and yarns utilizing a variety of jaw faces. Zwick’s testing platforms range from single column table top models to dual column table top models to floor standing models for high capacity solutions.
“As applications for technical textiles continue to evolve, the materials that are incorporated into these novel products evolve as well – requiring more sophisticated analysis of strain,” he said.
Zwick has responded to changing customer needs in this area through its development of novel solutions for extensometry. With a suite of extensometers designed to address strain measurement challenges in compliance with industry standards, Zwick enables textiles manufacturers to select the extensometer that best meets their needs, Wittenzellner said.
For samples where whiplash is not a concern, Zwick offers contact extensometers in clip-on and sensor arm formats. For whiplash-prone samples, Zwick has developed a suite of non-contact extensometers that includes the laserXtens® laser extensometer, the videoXtens® video extensometer and an optical extensometer.
“In high capacity applications such as seatbelt testing, specimens can exhibit whiplash, which has the potential to damage the sensor arms of sensor arm extensometers. The laserXtens or videoXtens extensometers offer alternatives without sacrificing measurement accuracy,” said Donohue.
Through its industry-leading testXpert® II measurement and control software, Zwick supports a wide range of applications - from tensile tests on fibers and filaments and elastic behavior of elastomeric yarns to strength testing as well as delamination and adhesion of fabrics - in accordance with corresponding ASTM, ISO and DIN standards.
“An intuitive interface in combination with a robust standards library makes testXpert II a valuable tool for high throughput test lab environments. We recognize that textiles span a wide range of applications and we have incorporated standards that address this range of needs. Our systems are capable of running tests as diverse as tensile tests of airbag fabric in accordance with ISO 13941-1 to tests on conveyor belts as prescribe by ISO 283-1,” Wittenzellner said.
