TST 2 shows the way when it comes to thermal shrinkage testing of filament yarn such as tyre cord. The tabletop device offers versatile testing of up to two samples for either shrinkage % or shrinkage force or both in one and the same test run.
Users all over the world appreciate the flexible operation and the vast evaluation possibilities of the TST software. The Thermal Shrinkage Tester is also available as TST 510/250 for testing of up to 10 yarn samples simultaneously, or as TST 1 for thermal shrinkage testing of one wider sample such as synthetic film of up to 50 mm width.

OPUMETER is a handheld instrument, which is used to measure the spin finish content as OPU% directly on the running yarn after the spin finish nozzle. It may be used for POY and FDY and for any conductive spin finish composition. The yarn just has to be held between the ceramic pins of the instrument for some seconds in order to yield a real-time value of the present spin finish concentration. It is a relative measurement, referring to the conductivity of the spin finish on the passing yarn.

By means of this method, also short term deviations of the spin finish level due to air bubbles, faulty pumps or applicators may be detected and reacted to without any delay. OPUMETER offers a high degree of flexibility, both when it comes to location of use and results evaluation - it may be used at different production machines within short time. That way, it enables quick reactions to process malfunctions, with cost savings as a result.

Lenzing Instruments' ELKOMETER 200 provides yarn producers and converters with a high-volume precision tool for off-line defect detection. A powerful yarn take-off unit guides up to eight parallel positioned yarn samples through PROMPT OLO online sensors. Defects such as thin- and thick places, broken filaments and fluff are detected and reported in terms of quantity and position. If an in-depth defect analysis is requested, images of each detected defect can be generated by means of the optional DEFECT VIEW camera system, which is installed at one of the positions. Additionally to the pure inspection mode, a special defect assessment mode enables human inspection by stopping the system after each detected defect.

For decades, LISTER AC by Lenzing Instruments is the trusted choice for measuring the time for a known volume of liquid to pass through a nonwoven material, i.e. the liquid strike-through time. The test procedure conforms fully with INDA/EDANA standards WSP 70.3 and 70.7 and highest reproducibility and comparability are guaranteed for. However, some applications require frequent testing, leading to resource and cost constraints. With the time- and resource saving newcomer LISTER AUTO, users are offered an automatic alternative for the liquid strike-through test: A turn table with five sample positions successively presents the nonwoven material to an integrated LISTER unit. A timer guarantees for accurate and unbiased results also in case the repeated LISTER test mode is selected. LISTER AUTO provides a flexible and efficient solution while retaining the benefits of the Lister AC.

The quality of interlaced yarns depends on node count, regularity, and tenacity of the nodes; crucial for downstream processes such as weaving and knitting. RAPID 600 V offers automated and servo-controlled pretensioning, string-up and sample removal for faster, more accurate testing of entangled filament yarns. Using a vertically moving pin, it detects entangled nodes, determining their count, distance, and tenacity per ASTM D4724. The mechanical pin system ensures only nodes meeting operator-defined tension are accepted. Designed robustly, it is not confined to laboratories, but can be used near production lines for early testing. This facilitates quicker evaluation of interlace quality and prompt reaction to irregularities. With total computer control and user-friendly handling, RAPID 600 V streamlines testing, leading to significant labor savings. An even higher automation degree can be achieved with RAPID 600 V in combination with SESS, Lenzing Instruments' Sequential End Sampling System for automatic and successive measurement of a customer-specified number of bobbins, directly off the transport buggy.
