           Yarn producers today know that both quality and performance are essential if they are to meet continuously rising demands of customers in weaving and knitting mills. Yarns must have the look, feel and functionality to satisfy these requirements. With the launch of the Uster Tensojet 5, the concept of tensile testing is extended to provide a total package: precise measurement of yarn strength, combined with reliable protection against quality claims based on accurate forecasts of performance in subsequent processes.

A priority for any yarn is the ability to withstand downstream processes – without causing stoppage or affecting production efficiency. Whatever the fabric application, it is high-speed weaving and knitting which exert the greatest stress and strain forces on the yarn. So, its strength and elongation properties must be suitable for the fabric-making process, as well as for the ultimate end-use.

Minimum strength and elongation properties are needed to prevent yarns from breaking or being damaged in downstream operations, as well as avoiding blemishes on end-products in weaving. So, accurate tensile strength values are important, particularly for warp yarns, which are placed under tremendous stress.

Uster is committed to meeting the industry’s need for increasingly effective and accurate tensile testing. For decades, Uster laboratory instruments have set the global standards for strength and elongation measurement of staple, as well as filament, yarns. In 2018, a new generation has been launched. The Tensorapid 5, the ‘go-to’ tensile tester providing precise data, was introduced in March. Now, the most powerful and comprehensive tensile tester ever is introduced: the Tensojet 5 can operate at speeds of 400 m/min., and integrates with the Total Testing Center to deliver a new range of overall benefits to both quality assurance and profitability for yarn manufacturers.
