Mahlo presents a wide range of sensors at INDEX23

When the nonwoven industry meets at the leading trade fair INDEX in Geneva from 18 to 21 April, the expert team of Mahlo GmbH + Co KG awaits trade visitors from all over the world at stand 4112. They can find out how the right measurement technology enables more efficient and high-quality production of nonwovens. Thanks to a broad sensor portfolio, Mahlo offers the right solution for virtually any application.

Nonwovens in focus

"We want to support manufacturers in optimising their production processes and thus also the end product," says Matthias Wulbeck, Mahlo product manager for QCS. Because, like many other industries, the nonwoven sector is struggling with challenges such as rising prices for energy and raw materials, long delivery times and uncertain supply chains. In order to continue to produce economically and on time, it is therefore necessary to save resources and avoid faulty production as well as unnecessary process times. "Our Qualiscan QMS measurement and control system helps to do just that."

With a wide range of sensors, different measuring techniques and the corresponding measuring bridges, practically all tasks regarding the control of basis weight, moisture, thickness, fibre content, and air permeability can be solved in a cost-efficient and practical way.

Example spunlace production

As an example, Wulbeck mentions spunlace products. They mainly consist of fibres such as cotton, PE, PET or rayon. They absorb light in the near-infrared range. Water and all other materials have different spectral ranges and can thus be distinguished. The near-infrared sensor Infrascope NIR determines the moisture content and the basis weight of different materials by attenuating the light in certain wavelengths.

Due to its very high spectral resolution, the sensor can distinguish between components with very similar but not identical IR absorption and achieves high measurement accuracy. "Up to 0.05 g/m2 of the respective coating weight is possible," says Wulbeck.

Mahlo has already successfully implemented very many such applications and offers the user a perfect tool with high measuring accuracy and easy handling. Visitors to the Index will find further solutions tailored to needs and requirements from the Mahlo experts at stand 4112.

Smart Quality Control for Technical Textiles

In the end, what matters is the result: a filter that performs reliably, a membrane that remains stable in storm conditions, a composite material with precisely defined properties. But the path to achieving this is demanding. In the production of technical textiles, numerous parameters interact – and even the smallest deviations can have major consequences.

New Gravimax MMX-R X-ray sensor platform opens up new application fields

The demands placed on quality control in web-based production processes are increasing: materials are becoming more complex, basis weights are varying more widely, and at the same time, pressure is growing to make processes more efficient and transparent. Precise measurement data across the entire web width has therefore become a key factor in ensuring stable production processes. With its new Gravimax MMX-R sensor platform, Mahlo introduces a radiometric measurement solution designed to set new standards in determining basis weight and material composition. The platform combines advanced X-ray technology with newly developed signal processing, enabling measurement tasks that previously often required multiple sensor technologies.

Orthopac RVMC-20 plus: German Engineering for Smarter Weft Straightening

In times of rising cost pressure and growing quality demands, textile producers worldwide are searching for solutions that combine precision, efficiency, and sustainability. With its latest innovation, the Orthopac RVMC-20 plus, Mahlo once again demonstrates the strength of German engineering: improving proven technology to meet today’s challenges.

Stefan Moll becomes new CEO of the machinery manufacturer

Starting January 1, 2026, Stefan Moll will take over the management of Mahlo GmbH + Co. KG, the world’s leading provider of measurement and control technology for web-shaped materials. With this move, Mahlo is focusing on the long-term safeguarding of its market position and technological leadership. The current CEO, Rainer Mestermann, will leave the company after 14 years as part of a planned succession arrangement.

Expansive innovations converge in Shanghai as Yarn Expo Autumn 2026 opens doors next week

With just days to go, industry enthusiasm is building for the opening of Yarn Expo Autumn, Asia’s premier yarn and fibre trade fair, running from 25 – 27 August at the National Exhibition and Convention Center (Shanghai). Across 27,000 sqm in Hall 8.2, buyers will find nearly 600 exhibitors from 14 countries and regions, spread across seven specialised zones that range from cutting-edge man-made and regenerated fibres to time-honoured cashmere and silk. Beyond the extensive sourcing options, a fringe programme of trend showcases, presentations and product launches rounds out the three¬day event with design, innovation and market intelligence.
