From the Sector

International technology Group ANDRITZ has received an order from Amarande SAS to supply an elliptical cylinder pre-needler for their plant in Lussac les Châteaux, France. This machine will process shoddy and natural fibers for the production of heavy felts. Installation and start-up of the machine are scheduled for the second quarter of 2021. The new needlepunch production line with the high-performance ANDRITZ cylinder pre-needler will allow Amarande to offer high-quality products and thus open up new market opportunities.

ANDRITZ offers a complete range of elliptical cylinder pre-needlers serving different weights, widths, speeds and punching capacity. Over the years they have become a must for production of heavy products, special applications and also for demanding applications like automotive. They are a key success factor in enabling the subsequent needling machines to process heavy batts smoothly and control the progressive draft through the consolidation process.  

Established in 1990, Amarande is an important French producer of nonwovens, specialized in the production of felt and wadding from recycled textile and natural fibers (wool, cotton, hemp, flax, jute, etc.). The company operates in various markets such as furniture, green spaces, horticultural crops, and insulation.

Paper Converting Machine Company (PCMC) has announced its industry-leading wet wipes folding machines the Rx200 and Mako Clipper are now available with high-content alcohol, measuring as much as 70 percent.

Previously, PCMC wet wipes machines operated with less than 20 percent alcohol, producing disinfectant wipes for personal, home, industrial and automotive use. However, the COVID-19 pandemic has created a spike in demand for sanitizing wipes that contain at least 70 percent alcohol, the key component in killing or deactivating viruses.

To help manufacturers meet the increased demand, PCMC redesigned its Rx200 and Mako Clipper to safely operate with high-content alcohol. The new designs feature increased air exchange for better ventilation and additional sensors to eliminate the risk of flash points and fires. The machines also include IDS 150/300 integrated dual stackers and a redesigned Mako saw to meet more stringent regulations and higher machine performance expectations.

• 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.

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.

• 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”.

Dow introduces DOWSIL™ IE-8749 Emulsion, a new generation of durable water repellent finishes for fabrics based on silicone chemistry.

Studies conducted on a variety of textiles substrates based on DOWSIL™ IE-8749 Emulsion treatment demonstrate improved fabric retention compared to standard silicone finishes – thereby providing continued water repellency after multiple washes. Unlike many conventional finishes, DOWSIL™ IE-8749 Emulsion finish does not need to be regularly heat treated to restore the water repellency performance, which is a key advantage for the durability of the final product.

By incorporating a DOWSIL™ IE-8749 Emulsion treatment into their finishing processes, textile finishers receive greater control over the hand feel of the fabric - an important parameter driving consumer choices today. Depending on specific need, this can range, from a very soft hand feel that is characteristic of silicone when used alone, to a firmer hand with the addition of cross linkers.

The technology powering DOWSIL™ IE-8749 Emulsion was developed through a collaboration between Dow and Nicca Chemical.

• The Bavarian Kelheim Fibres GmbH has become the first viscose fibre manufacturer worldwide to receive EMAS certification.

“Our aspiration is that our fibres offer an eco-friendly and high-performance alternative to synthetic materials”, says Craig Barker, CEO at Kelheim Fibres. “So, it’s not enough that our fibres are made from renewable resources and that they are fully biodegradable – our environmental awareness must include the whole production process and all that goes with it if we want to safeguard our credibility.

The EMAS certification proves that we take this responsibility seriously.” EMAS stands for “Eco Management and Audit Scheme” and is a standardised eco management certification system developed by the European Union. EMAS includes the globally applicable ISO 14001 standard and goes beyond its requirements by demanding more transparency and continuous improvement: Certified companies report in their annual EMAS Environmental Statement on their environmental goals and their progress in meeting them.

During the audit preceding the certification, the independent environmental auditor thoroughly investigated all departments of the company, from the production itself to the company canteen. He found no non-conformances and was impressed by the competence and the high sense of responsibility among Kelheim’s employees. In contrast to the EU Ecolabel and similar certifications, EMAS does not apply to individual products or services, but certifies the complete environmental performance of the company. This benefits not only the protection of the environment and climate, but also the improvement of a company’s ecoefficiency.

Craig Barker: “An efficient environmental management system ensures that economy and ecology go hand in hand – that gives us a decisive competitive edge.”
