Lenzing Instruments presents innovative testing systems for optimum quality Textechno group member Lenzing Instruments at hall 12, booth B52 presents quality assurance measurement systems for producers of filament yarn, staple fiber, nonwoven and woven textiles as well as for plastic film. Customers are offered solutions for various automatization requests, including laboratory testing equipment, at-line high volume testing instruments together with online monitoring systems. As a pioneer within the area of online sensor technology, Lenzing Instruments is an acknowledged partner for industry 4.0 solutions offering real-time defect control and continuous monitoring of vital material characteristics. Lenzing Instruments highlight following products:
PROMPT sensor technology for filament yarn The continuous and real-time process control of defects and vital yarn characteristics is given by the PROMPT sensor technology in combination with the PROMPT Visualization software. The system offers high reliability and multipoint access to monitored results. A range of intelligent sensors offers control of defects (fluff, broken filaments etc.), yarn diameter, interlace, spin finish and yarn tension. An even more thorough analysis of yarn defects is offered by Defect View and Fray View: Here, the PROMPT defect control sensors are combined with a highresolution camera, which generates images of detected broken filaments, fluff and other deviations from set quality levels. If used together with a yarn take-off unit, Defect View and Fray View can be applied for offline application in the laboratory; PROMPT LAB. This is also the case with the ELKOMETER: Up to eight yarn packages are simultaneously tested for yarn characteristics and defects. A special defect assessment mode triggers the yarn motion to be stopped immediately after detection which

For quick checks of the spin finish content on one single spinning end, the hand-held sensor OPUMETER provides fast and clear information about the momentary OPU/FOY content on the running filament yarn. Within seconds, results are displayed graphically and numerically on a portable evaluation unit.
Thermal Shrinkage Testing TST 2 is part of Lenzing Instruments offer of equipment for thermal shrinkage testing of filament yarn, tapes and plastic film. TST 2 tests up to two samples simultaneously for percent shrinkage and/or shrinkage force. The shrinkage behaviour is either observed at a constant temperature for a certain time period or during a temperature slope. The flexible software program also offers an option of customized testing sequences to be created.
High-volume fiber crimp inspection Online and real-time crimp control of staple fiber is provided by the Crimp
be traced back to specific bale ID’s and are given as average crimp count (counts/cm), long crimp, micro crimp and crimp distribution. The new intuitive and flexible software, higher image frequency and enhanced possibilities for monitoring fibers of a wider colour range characterize the new CIS 300.
Absorption testing of nonwovens Essential material tests for nonwoven topsheet (coverstock) aimed for hygienic applications include verification of performance indicators such as liquid strike-through, rewet and run-off. All three areas are covered by Lenzing Instruments Lister AC, Wetback and RUNOFF. INDA/EDANA-standardized function and design ensure for accurate and reproducible feedback on the fluid management of the nonwoven material.
