• Neuentwicklung im Bereich hydrophobe Oberflächen

Die SAUERESSIG Group fertigt seit Jahrzehnten Druck- und Prägewalzen für die unterschiedlichsten Industrien. Neben seinem umfassenden Produkt- und Dienstleistungsangebot legt, das Unternehmen einen starken Fokus auf Innovationen. Die hauseigene F&E-Abteilung arbeitet spartenübergreifend an Neu- und Weiterentwicklungen für die Bereiche Produkt- und Prozessoptimierung. Die Experten von SAUERESSIG Surfaces schaffen mit ihrer jüngsten Innovation einen wegweisenden Fortschritt am internationalen Markt:

Mit Hilfe eines modifizierten Heißprägeprozesses gelang die Erzeugung hydrophober Oberflächen - einer speziell entwickelten Oberflächenstruktur zur Nachahmung natürlicher Effekte. „Hydrophob kommt aus dem Altgriechischen und bedeutet ‚wassermeidend‘. Ein Extrembeispiel für solch eine Oberfläche sind die Blätter und Blüten der Lotusblume“, erklärt Robert Staudte, Sales Director SAUERESSIG Surfaces. Diese ist rau und zusätzlich mit wasserabweisenden Substanzen bedeckt. Durch seine typische Noppenstruktur gibt es nur wenige Kontaktstellen, so dass Tropfen darauf fast rund erscheinen. „Diese geringe Benetzbarkeit ist die Grundlage der von uns entwickelten Mikrostruktur. Je nach Material können wir mit Wasser auf der Oberfläche einen Kontaktwinkel von bis zu 150° erzeugen.“ Damit perlt Flüssigkeit sehr gut ab und aufliegende Schmutzpartikel werden leicht weggespült. Diese Selbstreinigungsfähigkeit vermindert die feste Anhaftung von Verschmutzungen aller Art und vereinfacht die Reinigung erheblich. Besonders bei Bodenbelägen und Möbeloberflächen sind Eigenschaften wie wasserfest oder feuchtigkeitsresistent für viele Verbraucher zum Synonym für besonders unempfindliche und pflegeleichte Produkte geworden. „Wir sehen in den hydrophoben Oberflächen großes Potenzial für die unterschiedlichsten Bereiche. Mit mittels Pikosekundenlaser gravierten Prägewalzen, ist es uns bereits gelungen, diesen Effekt auch in Coatings und Folien zu übertragen“, so Staudte.

SAUERESSIG Surfaces bietet seinen Kunden dazu umfassende Service- und gemeinsame Entwicklungsoptionen. Neben technischer Beratung und der Abwägung von Umsetzbarkeiten, unterstützen die Experten auch mit individueller Strukturentwicklung. Im hauseigenen Technikum können zudem Testabprägungen mit Heißprägeverfahren auf Folien bis 200°C realisiert werden.

• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, today announced the launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks.

Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics, and then used it as part of its ADVANCED DENIM concept. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realize substantial resource savings in water, wastewater, cotton waste, and energy.

Over the years the company has worked with its textile manufacturers and partners to improve the Pad-Ox process, in particular woven applications such as chinos and casual wear. To achieve maximum positive impact, Archroma is using its Diresul® range of low sulfide sulfur dyes and, more recently, its innovative plant-based range of EarthColors®. A wide selection of dyes from these two ranges have received the Cradle-to-Cradle Product Innovation Institute’s Platinum Level Material Health Certification.

Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions for more than 25 years, accompanying the textile industry on their way to producing with zero discharge. In 2008, the company introduced its G2 Dynamic the first ozone treatment for continuous fabric that dramatically reduces the amount of water and chemicals used, while at the same time saving costs at the mill and eventually at the garment finishing facilities. This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser. This machinery can be used along with Pad-Ox technology to help cleaning fabric thus improve fastness results. While it allows process to work at room temperature.

Project focus on water saving
Archroma and Jeanologia therefore understandably decided to team up and combine their expertise in sustainable dyeing and finishing technologies. The objective of the project was to improve the Pad-Ox dyeing process even further, in particular in one area that still offered room for positive impact: temperature and fastnesses.

The new ‘Pad-Ox G2 Cold’ dyeing process works thanks to the insertion of very small machinery into the existing finishing range process, using cold processing and thus operating with much less water, carbon footprint and energy than traditional benchmark fabric finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.

Maximum savings can be achieved by mills and garment manufacturers who wish to switch from a conventional dyeing process straight to ‘Pad -Ox G2 Cold’ to obtain high quality fabrics for comfortable and casual wear.

Decision SA, part of the leading European composites consortium, Carboman Group, and a specialist in the development, prototyping and production of large composite structures, is proud to announce a new direct mould tooling technology for aerospace.  Decision’s latest tooling solution provides OEMs and manufacturers with short lead times for highly stable direct moulds for series production both in and outside of the autoclave at temperatures of up to 180˚C.

Decision and Carboman recently delivered the first customer moulds using the new technology, providing a tooling glass prepreg, stainless-steel backed direct female mould tool created for the series production of a Class 3 fairing to a leading European aerospace OEM. Decision has immediate availability and capacity for similar tooling projects with lead times currently as short as six to eight weeks.

With no traditional plug or mould pattern required, Decision’s direct mould process starts with the group’s engineers selecting a material combination for the tool surface and support structure that will provide the optimum match between the coefficient of thermal expansion (CTE) of the mould and the composite part to be processed.  The CNC machined composite face sheet is supported by a stress-relieved metallic or composite backing structure before final post curing and machining is completed. The principal benefit of this novel approach, aside from removing the need for costly and time-consuming plug production, is the production accuracy delivered by the closely matched CTE of the mould tool and the finished composite part.

The autoclaved composite tool surface is not only extremely dimensionally stable up to processing temperatures of 180˚C, but it can also be configured with additional metallic inserts or fixtures if required.  

Produced in an EN 9100:2018 controlled production environment, and with CMM checks before and after machining, the new direct composite tools have dimensional tolerances of +/-0.2mm.  The available tooling dimensional envelope is currently defined by Decision’s 2200mm x 6000mm autoclave.

“With our new direct tooling technology, we are able to combine the highest technical standards in dimensional accuracy and thermal stability with extremely short lead times.  Decision and Carboman Groups’ combined mission has always been to develop the construction methods for tomorrow’s composite structures, and we believe that this tooling solution will allow our customers to accelerate the implementation of the next generation of high-performance carbon fibre aerostructures and components” Grégoire Metz, Managing Director, Decision SA.

This special compound increases laser effect on indigo or dischargeable dyestuff, saving time and energy for a swifter production. Due to the speedy process it also prevents fabric tearing whilst focusing on giving a used look.

AQUALESS AGED
Ideal to give abrasion effects on denim, this waterless treatment has a reduced impact on the environment and can be applied in combination with Oz-One powder both on black and indigo denim.

OZ-ONE POWDER
The sustainable (chlorine and potassium permanganate free) way to give denim that distressed and worn look, with no need of water or high temperatures.

AQUALESS MISSION meets the needs of the industry to reduce water in manufacturing operations, pledging to meet UN’s 2030 SDG 6 of clean water and sanitation, and by doing so protects the planet and its resources.

• BIONIC-FINISH®ECO Fluorine-Free, Water Repellent Finishes for Ultimate Performance

In recent years, many scientists have shifted from favoring a “primordial soup” in pools of water to hydrothermal vents deep in the ocean as the original source of life on Earth. Regardless what the real beginning really was, water was certainly involved in the process some 3,5bln years ago. And since then, Mother Nature designed many ways to benefit of water and to be sheltered from it. Many engineering challenges humans face can be solved by turning to those 3,5bln years of experience and by using natural design as springboard. That’s biologically inspired engineering or, in short, bionics. BIONIC-FINISH®ECO of RUDOLF GROUP is Mother Nature’s work reproduced on textiles and apparel to protect us from water. To perform.

Back in 2003, RUDOLF GROUP borrowed from Mother Nature the idea of dendrimers (from dendron, Greek word for ‘tree’), molecules made of multi-functional branches that interact among themselves, co-crystallize, and self-organize into highly ordered, multicomponent systems. These hyper-branched polymers attach to the textile and embed fluorine-free, durable water-repellent performance.
In 2021 BIONIC-FINISH®ECO comes as a reviewed and extended family of unique nonhalogenated, APEO-free, fluorine-free formulations suited for different materials and designed for different applications and needs. Still very much based on patented dendrimer technology, the new and strengthened BIONIC-FINISH®ECO’s product portfolio:

• Provides non-fluorinated and highly durable water repellent textile finishes for high-performance, professional applications (e.g. when brushing resistance is required);
• Delivers highly efficient and durable performance with low application amounts thus not affecting fabric feel and appearance (e.g. when remarkable softness is important);
• Fulfills a range of challenging technical requirements (e.g. minimal impact on flame retardant properties of technical fibers);
• Is suitable for both sportswear and outdoor applications, as well as for casual apparel and fashion clothing;
• Is bluesign® approved, ZDHC chemical gateway certified and compliant with most RSLs;

BIONIC-FINISH®ECO new portfolio includes universal and versatile solutions targeting the most standard requirements, as well as customized solutions that meet more demanding and specific expectations such as improved resistance to dry-cleaning. “None of us can entirely predict where our voyage will lead” says Dr. Gunther Duschek, RUDOLF GROUP Managing Director. “However, BIONIC-FINISH®ECO of RUDOLF GROUP will always be the fluorine-free, durable water repellent for ultimate  performance. As it is today”.
