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. Visitors 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.
“We want to support manufacturers in optimizing 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 basic 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.
