18.01.2019 INNOVATIVE SOLUTIONS EVEN FOR COMPLEX SCENARIOS

Mahlo presents quality control “Made in Germany” at ICE Europe

It’s ICE time again in Munich! From March 12 to 14, 2019 the international leading trade fair for finishing and processing of paper, film and foil draws a professional audience from all over the world. At stand A5-1510 they can discover for themselves the wide range of quality control technology of the German machine manufacturer, Mahlo GmbH + Co. KG.

“Manufacturers are not only concerned about sustainability with the manufacturing process and the end product. In addition, coating processes become increasingly demanding to meet the expectations of the customers”, says Mahlo’s Area Sales Manager, Matthias Wulbeck. The expert for quality measuring technology knows: “With the Qualiscan QMS we offer a solution that facilitates new standards to coating operations.” With the renowned on-line measuring and control solution, sensors traverse on stable measuring frames across the entire fabr

 

ic width and determine parameters such as thickness, basis weight, density, application thickness and moisture. At the same time, they log and control the required features. Depending on the application and the product, beta, X-ray or infrared emitters are used.

Mahlo’s exhibits at ICE 2019

At the ICE Mahlo also presents the measuring bridge Webpro XS, the most compact version of the O-frames. Installation is therefore possible even where space is at a premium. The Webpro XS manages product width from 0.2 to two metres and can accommodate one Mahlo sensor. Depending on the model, it measures key parameters such as film thickness, moisture or basis weight.

Interested parties can observe on special demo towers how exactly measurements are carried out and how the results are presented in a clearly arranged manner. With them Mahlo introduces two sensors from the comprehensive portfolio, which are used especially with complex requirements. The Infralot IMF measures important product specific parameters such as moisture and coating weight by optical analysis of reflected light energy in the near infrared range without contact. Using the Same Spot Technology makes the analysis in parallel possible. Depending on the application, the Infralot IMF is available as transmission or backscatter sensor.

The Optoscope WLI is employed for especially thin coats where other systems reach their limits. The sensor is able to measure varnish coats down to a thickness of 0.4 μm using the white light interference method. With adhesive coats on polymer film measurement of minute applications down to 1 μm is possible. What’s more, the Optoscope WLI is able to determine even extremely thin coats in the nm range indirectly with aqueous or solvent-based applications on film, depending on the solids content. The constant ongoing development of the sensor has ensured that practically no passline effect occurs. This guarantees extremely precise measuring results.

Saving costs and energy

“Especially in the finishing industry, transparent production processes help save cost and increase product quality” says Wulbeck. Mahlo possesses comprehensive experience and a wide range of measuring technologies. Eleven different sensors are available for the Qualiscan QMS quality measurement system using also, in addition to the methods mentioned, beta and X-ray transmission, laser triangulation or light band shadowing. Developing the right concept for nearly any application is the goal. The Mahlo Team looks forward to interesting conversations and questions about the latest development at booth A5-1510

BRÜCKNER Heat-recovery and exhaust air pollution control at Getzner AG

Getzner AG in Vorarlberg, Austria is today the leading company for the production of African damask fabrics and one of the leading manufacturers of shirt fashion fabrics.

Figure 1: Getzner AG in Bludenz, Austria.

The new production halls at Getzner AG’s main plant in Bludenz, fabrics are woven and finished for ready-made garments. The fabrics are finished in special processes mainly on new BRÜCKNER stenters.

As substances evaporate from the fabric during the textile finishing processes, the stenters have to be vacuumed off and this exhaust air has to be cleaned before being emitted into the environment.

The exhaust air treatment on the new stenters of Getzner AG is carried out by a multi-stage BRÜCKNER ECO-HEAT and ECO-AIR system.

In the first ECO-HEAT heat-recovery system, heated fresh air is generated for the drying process, which noticeably reduces energy consumption. In the second ECO-HEAT heat-recovery system, water is heated for the company’s internal heating system and thus, depending on the heating requirement, up to 85% of the invested heat energy is recovered.

The pollutants from the exhaust air are condensed and separated in the subsequent ECO-AIR exhaust air scrubber. A silencer behind the exhaust air fan reduces the exhaust noise to a minimum.

The proven ECO-HEAT components guarantee high heat transfer efficiency and a particularly robust and maintenance-friendly design. Since the heat exchangers have to be cleaned at regular intervals from unavoidable deposits in order to maintain full performance, they are easy to remove. The heat exchangers are boiled regularly in the cleaning bath supplied.

As Getzner AG has replacement heat exchanger modules in stock, the heat exchangers are cleaned without any time pressure.

With this modern multi-stage exhaust air system Getzner AG achieves a high energy efficiency because most of the exhaust air heat is recovered in BRÜCKNER ECO-HEAT systems.

In addition, the picturesque environment is not polluted by smoke, noise, and odors from the production process, thanks to the BRÜCKNER ECO-AIR exhaust air cleaning system.

Concrete Proposals For Tomorrow’s Composites From HOFZET® And Vandewiele

Unique Vandewiele jacquard technology is proving central to research exploring the potential of hybrid woven technical textiles for a leading German research institution.

TW Special Report

Along with a number of partners, HOFZET® — the Application Center for Wood Fiber Research of the Fraunhofer Institute for Wood Research based in Hannover — has developed new forms of bio-hybrid fibre reinforced composites (bio-HFCs) containing the highest possible bio-based content.

“Bio-HFCs are already successfully employed in a range of sporting goods, such as racing cycle frames, tennis rackets and skis, where they have a number of advantageous properties,” explained technical textiles specialist Jana Winkelmann. “In particular, they have a low density, high vibration damping and flexible mechanical characteristics, in addition to the added benefit of containing substantial renewable raw material content.

“We are developing new and practical combinations of natural and high-performance fibers, such as flax, hemp and viscose with carbon, glass or polyamide in multi-layer fabrics. These have application-oriented properties with the potential to be scaled up for mass production, and are targeted at applications in both the automotive and construction sectors.”

One Of A Kind
The development work is being carried out on a special double-rapier weaving loom and Vandewiele Jacquard attachment — the only one of its kind in Europe — at the Open Hybrid Lightweight Campus (OHLF) in Wolfsburg, not far from Volkswagen AG’s parent plant. It serves as a competence and research centre for cost-efficient lightweight engineering and innovative materials and manufacturing technologies developed by Volkswagen and its industrial and institutional partners.

The OHLF weaving technology is enabling the Fraunhofer experts to cost-effectively produce materials with complex, application-specific textile structures and integrated functions, in widths of up to 50 centimeters.

“We are producing load path-appropriate combinations of the different reinforcing fibres and additional matrix fibers to produce hybrid textiles which will provide simpler handling and faster processing, as well as flexibility in achieving the desired mechanical properties in the finished product,” said Winkelmann.

At present, a key HOFZET research focus is on composite reinforcements with a thermoplastic matrix, or organosheets, which offer reversible deformation and recycling potential in comparison with thermoset composite materials. The weaving loom enables the integration of thermoplastic matrix fibers into hybrid textiles as perfect thermoplastic prepregs. These prepregs can be shaped to a required form and turned into composites using hot pressing technology. This approach enables a reduction of process steps, cycle times and production waste. Furthermore, the process allows new design freedom, which enlarges the component spectrum of fiber-reinforced composites. The shaping, for example, can be carried out simply and quickly through thermoforming in a die or in the clamping unit of an injection molding machine.

A robot-controlled fiber-spraying unit further expands possibilities, allowing continuous filaments and yarns to be cut to a specific length and simultaneously wetted in an air stream with a mixture of resin and curing agent and sprayed onto a shaping tool.

Construction
In another project, flax-based multi-layer fabrics produced on the special HOFZET weaving system are being employed to reinforce concrete.

Textile-reinforced concrete has already proved to be durable, formable in diverse shapes and suitable for lightweight construction and so far has been based on carbon or glass fibers to replace the steel which is conventionally employed.

The flax-based textile is embedded in the given component in layers. Its stiffness is variable, so it can be arranged in a desired shape and could conceivably be cast to create curved contours such as domes and rounded wall elements.

“The quality of reinforced concrete made with a flax fabric is higher than that of the reinforced concrete in bridges,” says Jan Binde, a scientist at ZELUBA®, a second department of the Fraunhofer Institute for Wood Research based in Braunschweig. “The matrix — that is, the structure — is so dense that harmful substances cannot penetrate the component. This results in a far longer service life of several decades.”

“The natural fibers mesh very well with the building material and we can control how the textile is fixed in the concrete. The textile’s specific surface is variable. A reinforced concrete bridge with a span of 15 meters would be about 35 to 40 centimeters thick, while its flax counterpart would be considerably slimmer at 12 to 16 centimeters. This saves a lot of material.”

HOFZET next plans to make various modifications to the unique, advanced weaving system, in order to manufacture special spacer fabrics, for which the Vandewiele Jacquard will also play an integral part.

A special feature of the jacquard is that every warp of the fabric can be controlled individually. This results in an unlimited variety of patterns. By using different patterns it is also possible to change the structure from one-layer to multilayer fabric in a single process.

“We have further ideas for such new materials for both the automotive and construction sectors,” Jana Winkelmann concludes. “Watch this space.”
