Mahlo innovative solutions to

optimize the production

processes and the end products

Mahlo Qualiscan QMS
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.
