As a compliment to the widely used LISTER AC, Lenzing Instruments now introduces LISTER AUTO for determination of the liquid strike-through time of nonwoven coverstock or topsheet in compliance with EDANA/INDA standards WSP 70.3 and WSP 70.7. The multi-sample, high-volume testing capability is facilitated by a rotating turntable, presenting up to five individual samples consecutively to the integrated LISTER AC unit.
LISTER AUTO ensures fully automatic liquid strike-through measurements, thereby eliminating the need for manual test liquid handling. Atomatic discharge of test liquid facilitates controlled liquid feed, reducing subjective operator influence. The time-saving operation means optimum efficiency, which extends to the repeated test mode, where the integrated timer ensures consistent time spans between measurements.
Highlighting its efficiency and therewith cost-saving benefits, LISTER AUTO reduces the time and personnel resources required for liquid strike-through measurements. The system utilizes standardized filter paper, available from Lenzing Instruments, and operates by automatically discharging a known volume of test liquid onto the sample surface, measuring the liquid strike-through time electronically. Lenzing Instruments has a history of setting standards within this area for over 40 years and is partner of EDANA for the liquid strike-through measurement. The high degree of automation offered by LISTER AUTO guarantees for objective, accurate, and reproducible results, and is a valuable extension to Lenzing Instruments’ product line for testing of the liquid management of nonwoven materials.
In connection with International Quality Day in November 2023, Lenzing Instruments' former general manager Heinz Schneider gave an interview to the concept of quality.

What does umati refer to?
umati, short for "universal machine technology interface," is a collective comprising the machine building industries and their clients. Its purpose is to advocate for and encourage the implementation of open and standardized interfaces, utilizing OPC UA as the foundation.
What does OPC UA stand for?
OPC UA, which stands for "Open Platform Communications Unified Architecture," is a standardized communication protocol designed for industrial automation and Internet of Things (IoT) applications. It facilitates secure and dependable data exchange between machines, systems, and enterprise applications. Importantly, OPC UA ensures interoperability across different hardware, software, and operating systems, enabling seamless communication.
What are Lenzing Instruments' expectations of umati and the partnership?
Through this partnership, Lenzing Instruments emphasizes the importance of open, comprehensive, and certified communication standards that facilitate seamless integration between production machines, testing instruments, and control systems. By fostering a robust partnership, Lenzing Instruments aims to unlock the possibilities and actively contribute to shaping the future of integration using OPC-UA.
What are the advantages that umati offers to Lenzing Instruments and its customers?
umati provides Lenzing Instruments with the opportunity to demonstrate the seamless integration and reliability of their instruments within a wide range of production environments. This ensures that customers can have full confidence in the flawless integration of Lenzing Instruments' devices. Moreover, umati highlights the potential for deep interconnectivity, showcasing the advanced levels of connectivity and collaboration achievable through the use of umati standards.
How does Lenzing Instruments view the expansion of the umati initiative to the entire mechanical engineering industry?
Lenzing Instruments recognizes the growing demand from its customers to integrate with their unique production control and execution systems. It is of great significance to Lenzing Instruments that the OPC-UA standard is widely adopted throughout the mechanical engineering industry, fostering a shared understanding among those implementing OPC-UA. Lenzing Instruments believes that a key aspect of achieving this is through the broad utilization of companion specifications, which can facilitate seamless interoperability and collaboration across different systems and stakeholders in the industry.
For producers and converters of synthetic film, Lenzing Instruments now offers a new device, WP 100.
WP 100 is a roller press, which is used for proper sample preparation when testing the adhesive strength and other material properties of synthetic film. For these tests, adhesive tape is attached to film samples. The adhesive tape is then peeled off in order to analyse various material characteristics, such as the adhesive strength of the film. By means of two rotating drums and individual settings of the contact pressure, WP 100 enables an even adhesive force to be applied over the entire sample surface. Therewith, small air bubbles are eliminated and the heterogeneity of the adhesion is reduced. Since WP 100 was developed in close co-operation with a well-known plastic film manufacturer, users can be sure to get a roller press which meets their requirements for this application.
PROMPT OLO is a new optical sensor, which is ideal for quality control tasks with limited space conditions. The sensor with minimised dimensions monitors mono- and multifilament yarn for typical defects and decisive yarn characteristics. Even the smallest defects are detected by PROMPT OLO, thereby enabling online monitoring of defects in applications, where this was not possible before due to sensor limitations.
Bulky fibers and filaments used as filling material in cushions, duvets etc., are tested for their filling power, compressibility and recovery properties with Lenzing Instruments BT 100.
Highly reproducible results are guaranteed by the automated testing procedure, which also allows for testing of a high number of fibers during one and the same test run.
RUNOFF completes Lenzing Instruments product range for INDA/EDANA- compliant absorption testing of nonwoven coverstock or topsheet. Whereas the two standard setting instruments
Lister AC and Wetback give feedback about the liquid strike-through and rewet properties of nonwoven materials, RUNOFF analyses the absorption characteristics of a nonwoven specimen positioned on an inclined plane as being exposed to a constant flow of liquid. Features such as easy liquid collection and the possibility of various instrument adjustments make RUNOFF an easy to use instrument for controlled and reproducible measurements.
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.
