Textile chains for load-bearing applications

Load-bearing transport and securing elements are essential components in modern industrial applications. Chains, known for their space-saving interlocking mechanisms, low weight, and safety features, play a critical role in load bearing and lashing capacities. This research, conducted by the Institute of Materials Science (ifm) at Hof University of Applied Sciences, focuses on a patented braided textile chain (WO2018153813 A1) that offers significant advantages over traditional metallic chains, including reduced weight, buoyancy, and minimized noise and spark emissions, alongside lower production costs. The project's objective was to validate the textile chain, enhance its breaking load to three tons, and achieve Technology Readiness Levels (TRL) 5 and 6. This was accomplished through several key developments: - Adaptation of the yarn insertion techniques (TRL 4) - Modification of pattern techniques and machine parameters (TRL 4) - Validation of core and inlay yarns (TRL 4) - Development of cutting, finishing and end-sealing processes (TRL 4). TRL 5 and 6 were verified through comprehensive testing in relevant application environments.
