Uster presents new tensile test system

Uster Technologies, a leading high technology instrument manufacturer, is introducing its newly developed Uster Tensorapid 5, which aims to provide yarn spinners with accurate and effective tensile testing performance they can rely on.

“There is one essential requirement for any yarn, whether staple or filament: it must be strong enough to cope with the rigors of downstream processes, without causing production stoppages. High-speed weaving and knitting put yarns under powerful stresses and strains, so they need to meet the strength and elongation standards for subsequent processes and the required end-uses,” the manufacturer explains.

“No matter what the demands of the fabric end-use, minimum strength and elongation properties are needed to prevent a yarn breaking or being damaged in downstream operations. The Uster Tensorapid 5 offers testing of all kind of yarns. For over 50 years, the Uster Tensorapid has been renowned through the industry for its high precision and reliability.”

Accurate measurements

The Uster Tensorapid 5 is a strength and elongation tester, with a testing speed that is steplessly adjustable between 50 and 5000 mm/min. With a 500 N or 1500 N measuring head, the instrument covers the complete range of force and elongation testing, including all known tensile test procedures. Measurements and results comply with all the international standards, including ISO, ASTM, BISFA and Chinese test organisations. Data also integrates directly with the acknowledged global textile quality benchmarks, the Uster Statistics.

The Uster Tensorapid 5 has an automatic function with the capability of handling 40 samples. In case of a problem during feeding, the test continues, and the customer has the option to repeat the missing position at a later stage. This ensures a high sample throughput, user friendliness and test efficiency. The Uster Tensorapid 5 is configured for ergonomic sample preparation on the side which makes it fastest and most convenient for the operator. Vertical yarn guides allow for user-friendly operation. A limit editor shows the essential information, focusing on exceptions and outliers. Customised reports and long-term reports are in line with the Uster Tester 6 user interface.

Process control

“Integration of results with Uster Tester 6 allows users to profit from intelligent alarms through the Total Testing Center,” the manufacturer adds. “Smart reports integrate results from both evenness and tensile tests, providing an overview of the quality being produced. This enables fast reaction by the Quality Manager, to minimize complaints. The result is a complete mill quality system, integrating data from fiber, yarn and tensile testing procedures, both in the laboratory and in-process from the Uster Quantum 3 yarn clearers.”

“Uster Tensorapid 5 is the must-have tensile testing system for staple yarn producers who are committed to the Uster approach of managing a spinning mill with quality in mind for the ultimate satisfaction of their customers downstream.”

Tailor-made for filament

The specific needs of filament yarn producers are related to the continuing development of new products and application areas in demanding sectors such as technical textiles, as well as in apparel and home textiles.

The Uster Tensorapid 5-C is tailored specifically to high-precision filament testing, incorporating software covering the essential quality factors of strength and elongation. Information about the first break of a filament helps spinners guarantee high speeds in subsequent processes. The determination of yield point and natural draw ratio particularly help POY yarn producers to reduce claims.

The newly developed Uster Tensorapid 5 for staple yarn and the Uster Tensorapid 5-C for filament yarn play a vital role in the drive for improved handling efficiencies and precisely-specified yarn profiling between mills and their customers, the company says. “Tensile testing has been used in textiles since the earliest days of the industry and it will doubtlessly be important in the future. With the new generation of tensile tester, we are convinced we have products tailor-made for today’s and tomorrow’s industry,” commented Gabriela Peters, Product Manager Yarn Testing, Uster Technologies.
