UTESTER 5-C800 uTENSORAPID 4-C - Uster Technologies

Ultimate package for filament yarn testingFilament yarn producers have been depending on USTER ® quality controlfor more than half a century. They appreciate the unrivalled technicalknowledge underpinning the latest USTER developments for the sector.The two most important parameters for filament yarn quality are massvariation and yarn strength /elongation. Accurate, precise testing of thesetwo yarn characteristics is provided by USTER’s tailored package forfilament: the USTER ® TESTER 5 - C800 evenness tester and the USTER ®TENSORAPID 4 - C tensile - strength tester. The high - speed USTER ® TESTER 5 -C800 is part of the famous USTER ® TESTER range – a watchword forevenness testing throughout textiles – in a version that is tailor - madefor filament yarns. The USTER ® TENSORAPID 4 - C is driven by unique,specially written software to cater to the requirements of filament yarns.Results from both these instruments can be combined and integrated tooffer significant advantages in the monitoring of filament yarn quality atthe production stage, as well as assessing how the yarns will performin subsequent manufacturing processes.Filament yarn technology is progressing rapidly, in technical textiles aswell as apparel and home textiles applications, so it’s vital that testingcapabilities keep up with the pace of innovation. This applies not only tothe most widely used fiber, polyester, but also to many others, includingpoly amide, polypropylene, viscose, aramid, in monofilament andmultifilament types, across a range of yarn counts.With the USTER ® filament testing package, it’s all covered.

Precision and accuracy at highest speedThe USTER ® TESTER 5 is the 5th generation of an instrumentthat is acknowledged worldwide as the original andauthentic standard for yarn evenness measurement.Especially developed for filament yarn testing, the USTER ®TESTER 5 - C800 is part of a range of instruments with a strongreputation in the industry for accuracy and reliability. Now,with its high - speed testing capability of up to 800 m/min, itallows rapid quality control procedures geared to the outputlevels of synthetic yarn producers.Precise control of mass variation in filament yarns is thecrucial advantage of the USTER ® TESTER 5 - C800 – thanks toits use of the proven capacitive measuring system devisedby USTER ® . Testing of monofilament or multifilament canbe a complex process, requiring specialist solutions. Anexample is the unique mechanical twisting unit developedfor multifilament testing on the USTER ® TESTER 5 - C800,which optimizes the accuracy and reliability of the resultsobtained and speeds up to 800 m/min with steplessadjustability.Problems affecting filament yarns can be caused by severalfactors: polymer inconsistency, spinning process irregularity,faults in yarn cooling, winding and drafting, as well asmachinery defects. Even small mass variations from any ofthese factors can be magnified by the speed of the filamentprocess to affect many thousands of meters of yarn andcreating unnecessary waste.The impact of these quality shortfalls in downstreamprocesses such as draw - twisting, texturing and dyeingcan be serious – underlining the vital importance ofcomprehensive evenness testing.To suit customer needs, the USTER ® TESTER 5 - C800 canbe supplied with auto - changer for 24 samples, or as asemiautomatic model. Since test results can be affected byenvironmental conditions, the USTER ® TESTER 5 - C800 isalso equipped with a special sensor enabling temperatureand humidity to be measured directly at the tester.The most important test result– Coefficient of variation ofthe yarn mass– Coefficient of variation ofmass at various cut length– Relative count– Results supported by graphicalreports like mass diagram,the variance - length curve andthe spectrogram%0.50.40.30.20.101/1 1/1 Spectogram Diagram Mass Mass%50Top:Mechanical twister, evennesstesting of filament yarns– 5Bottom:Effect of nonoptimized air stream0 0.5 1cm–10in quench air duct on the diagram2 0 5 10 20 20050 1m 2 4005 10 20 60050 100 200 800 500 1km 2(left) and on the spectrogram (right)m mUSTER ® TESTER 5 - C800 canbe supplied with– Automatic model with packagechanger for 24 models or thesemiautomatic model temperatureand humidity sensor for themeasurement of the laboratoryconditions– As a semiautomatic model– With a special sensor enablingtemperature and humiditymeasurement
