Mahlo: next generation pattern control system

Large, artistic graphics, timeless glen check or exact pinstripes. This presents an increasing challenge for textile manufacturers to produce straight weft and straightened patterns. Here, the alignment according to the design often plays a greater role than the weft insertion. The manufacturer of measuring, control and automation systems Mahlo GmbH & Co. KG, Saal a.d. Donau/Germany, solves this problem with its improved Patcontrol PCS-20 system for pattern recognition and warp control. It straightens bow and skew distortions in technical textiles just as reliably as in terry cloth. Even goods that cannot be detected with conventional scanning systems do not pose a problem for pattern recognition.
The system uses camera technology to detect the position of the pattern and automatically and continuously determines the pattern repeat, measures the product width, and together with a straightener straightens the product distortion based on the print pattern.
New long-life LED lighting generates the maximum brightness on the market, thereby extending the scanning range for darker goods. Improved cameras allow brightness control by gain and exposure time. More than 2 cameras can also be connected per measuring point. This allows a higher resolution and even more accurate results. A Gigabit connection allows the transmission of large amounts of data. Using a mounting aid, the exact camera adjustment can be done easily and quickly. A compact interface box at the measuring point integrates the Patcontrol PCS-20 even more easily into the existing plant.
The system is also integrated into the mSmart digitalization concept. Users, machines and processes are networked with each other and meet all the requirements of Industry 4.0.

Monforts: sustainable leadership for GtA with new Montex wide width lines

Following the commissioning of 2 new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA - Gesellschaft für textile Ausrüstung mbH, Neresheim/Germany, is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.
The substrates of choice for digital printing are 100% polyester warp knits. The knitted construction has the advantage of elasticity, which is a plus in terms of flexibility for installers. Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.
The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 m long Monforts installation comprising a washing machine integrated with a 3.6 m wide, 7-chamber Montex stenter. The 2 new Montex stenter lines from the manufacturer of textile machinery A. Monforts Textilmaschinen GmbH & Co. KG, Mönchengladbach/Germany are both in expanded working widths of 5.6 m. They include the Smart Sensor system for the optimized maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.
The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

DITF: intelligent tablecloths

Current hygiene regulations require restaurant operators to ensure sufficient distance between guests. Intelligent table cloths could soon help with this often complicated seating management. Furthermore, with the help of sensor technology, restaurant visitors could place their orders directly into the fabric without contact with the waiter and even use play functions after the meal. The German Institutes of Textile and Fiber Research Denkendorf (DITF), Denkendorf/Germany, are conducting research on tablecloths that are not only smart but also feel like textiles and can be used despite having built-in sensors.
Intelligent textiles do not yet have the properties familiar from fabrics, such as flexible, pleasant feel and easy washability. Therefore, the DITF are developing a purely textile sensor technology as part of a research project funded by the Federal Ministry of Economics and Technology. This will be separated from both the energy supply and the data processing and the measured values will be transmitted inductively, i.e. wirelessly. The tablecloths interact with the electronics integrated in the table. Central functions are the detection of seat occupancy, ordering functions and an event and game application. Specially developed wrapping yarns are used for this purpose. The first functional models have already been created using embroidery technology, which uses electronics to detect and show approximation and touch in a table. In the future, patterns that measure illuminance could control the blinds in the smart home and thus make the seating area glare-free.
To ensure that the research results can be transferred to the industry on a production scale, various influencing variables such as the sensor yarn structure or the embroidery pattern are being investigated.

Coperion: high-performance concept for meltblown PP production

In a recent test series performed in its test lab, the supplier of compounding and extrusion systems, Coperion GmbH, Stuttgart/Germany, together with the technology licensor Lummus Novolen Technology GmbH, Mannheim/Germany, demonstrated the wide range of possible applications for the proven Coperion ZSK twin screw extruder series.
Within the scope of tests, various polypropylene (PP) pellets with extremely low melt viscosities were successfully produced. This so-called meltblown PP forms the raw material for the production of nonwovens, which are mainly used as filter media in medical protective masks. The results obtained now allow the concept to be easily transferred from laboratory to production scale. Thus, the production of such products on existing and new large-scale extruders becomes possible.
The tests are based on the ZSK extruder technology with ZS-EG side devolatilization and a screw design. The combination of a new screw concept for optimum dispersion and very good degassing thanks to ZS-EG technology secures high product qualities. This is achieved with very good process reliability independent of throughput rates and melt viscosity.
