Mahlo at the INDEX 2023: Nonwovens in focus

When the nonwoven industry meets at the leading trade fair INDEX in Geneva from 18 to 21 April, Mahlo GmbH + Co KG awaits trade visitors from all over the world to inform them about the right measurement technology enabling more efficient and high-quality production of nonwovens.

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.

When the nonwoven industry meets at the leading trade fair INDEX in Geneva from 18 to 21 April, Mahlo GmbH + Co KG awaits trade visitors from all over the world to inform them about the right measurement technology enabling more efficient and high-quality production of nonwovens.

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.

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.

"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."

Penn Textile Solutions setzt auf Prozesskontrolle von Mahlo

Penn Textile Solutions GmbH is one of the world's leading manufacturers of elastic fabrics for under-wear, corsetry, sportswear and swimwear, as well as highly functional textiles for technical applications. The fully integrated company with its own warping, circular knitting, warp knitting, dyeing and finishing facilities currently employs around 150 people.

Penn has long relied on Mahlo
Penn has relied on the cooperation with Mahlo for years. The manufacturer of measuring, control and automation systems for web-shaped goods has decades of experience in the field of process control. Until the summer of 2020, the textile manufacturer had been using a basis weight measurement system in the stenter frame outlet with beta radiation and manual control. "When the krypton preparations had passed their half-life, we had to make a decision: Exchange or replace the system right away", says operations manager Franz Schütte. They sat down with Mahlo representatives and looked for the best solution. Since the systems had already reached a high operating age and the measurement was limited to the basis weight, a new concept was decided upon. "Mahlo made us the best price-performance offer." The new system should be even more efficient and easier to operate for the special makes..

The compression zones of the functional fabric create corresponding distortions within the textile surface in its raw state, which have to be smoothed out in the fixing process. This work is now taken over by a process control system. The Mahlo Famacont PMC-15 with two measuring points automatically controls the leading of the stenter frame by continuously and contactlessly determining the mesh density. In addition, the Patcontrol PCS-20 process control system ensures that the dimensions of the different zones are recorded and also automatically controlled. "The previous beta-radiation facility was not able to collect this kind of data," explains the Penn operations manager. Another important aspect for the textile manufacturer: the complete and costly radiation protection is no longer necessary with the new systems.

Despite very good experience with Mahlo in the past, every change naturally involves a risk. Penn did not have to rely on theoretical considerations, however, but carried out tests in advance with appropriate sample material in the Mahlo test laboratory. The results convinced the decision-makers.
