From the Sector

The Hygiene Fibers Group of Indorama Ventures (IVL) came together at the Index Show to present an all-inclusive range of recycled and biodegradable solutions for Hygiene Fiber and Nonwoven applications.

The combination of polymers, technologies, processes and global reach supported by the Hygiene Fibers Group – one of three business segments that make up Indorama Ventures – positions it within the Hygiene industry to meet increasingly challenging market demand for innovative sustainable solutions within the hygiene sector. Across the six brands and companies that make up Hygiene Fibers Group – Auriga, Avgol, FiberVisions, Indorama Asia, Trevira and Wellman International – sustainability and supporting customers to achieve circular objectives is integral to all efforts and fundamental to the ethos of the Hygiene business segment.

At the Index Show, the Hygiene Fibers Group launched CiCLO®, a textile technology which allows polyester and other synthetic materials to biodegrade like natural materials do in wastewater treatment plant sludge, sea water and landfill conditions, reducing synthetic microfiber pollution generated during washing, and minimizing plastic accumulation in landfills caused by discarded textiles.

In line with the company’s commitment to support customers with high performance products, while also reducing the impact on the environment, several of the  Hygiene Fibers brands, including Wellman International, Trevira GMBH and Auriga, have been working closely over the last 12 months with the IAM team and the CiCLO® technology. Developments have focused on PET and rPET staple fiber and filament sustainable solutions for applications where recycling is particularly challenging, such as Hygiene, Home Textiles and Automotive applications.

Strengthening the profile of biodegradable offerings within the Hygiene Fibers Group’s sustainability portfolio, Trevira introduced a new range of bicomponent fibres based on PLA and PBS (polybutylene succinate) at the Index show. Both biopolymers offer an exceptional technological opportunity in terms of environmental care and sustainability, while delivering optimum performance. Equally to PLA, PBS is recyclable and up to 100% biodegradable under industrial conditions.

Efforts towards supporting customers to achieve circular objectives are a priority within the Hygiene Fibers Group. This is reflected in the recycled fibers expertise deployed across the segment. Four Hygiene Fibers Group brands, IVL Asia, Auriga, Trevira and Wellman International offer an extensive range of 100% recycled, accredited PET fibers, across a multitude of fiber and nonwovens applications.

The development and evolution of sustainable technologies is central to activity across IVL’s Hygiene Fibers Group, with particular focus on sustainable polyolefin solutions. FiberVisions and ES-FIBERVISIONS, leading Polyolefin mono and bico fiber brands and sister company Avgol, have partnered with UK-based Polymateria to commercially harness the innovative ‘biotransformation’ technology pioneered by Polymateria. The patented technology alters the properties of polyolefins to make them biodegradable in a natural process.  Other polyolefin sustainable innovations within the Hygiene Fibers Group were featured at Index include biosurfactant and biocolourant developments being undertaken by the Avgol team with FiberVisons progressing sustainable design solutions, including lightweight, high performance, reduced carbon solutions.

• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

As your development partner, vombaur facilitates innovative composites projects for challenging applications. In innovative and safety-sensitive industries such as automotive and aviation, chemical and plant engineering.  The composites experts at vombaur develop, create samples of and manufacture woven tapes and seamless round or shaped woven textiles by vombaur – in collaboration with the customer's enterprise development teams and individually for the respective projects. This is how novel and unique lightweight components made of high-performance textiles are created for visionary lightweight construction projects.

"Fibre-reinforced composites are the ideal material for future-oriented construction projects," explains Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "Their outstanding technical properties and design possibilities open up new and fascinating perspectives for construction projects. From building construction to civil engineering, from bridge construction to interior design. As an experienced development partner for sophisticated lightweight components, we at vombaur contribute our seamless solutions to these kinds of future-oriented projects."

Truetzschler Nonwovens will deliver equipment to enlarge an existing spunlacing line - put into operation in 2015 at the Turkish Eruslu Nonwovens Group - into a flexible, state-of-the-art production line for various light to heavy weight sustainable nonwovens.

Last year Eruslu decided to broaden its portfolio in the wipes segment by adding biodegradable products from renewable resources. The group took full advantage of the 2015 small capacity line and went for:

• a second NCR random and a NCA airlay card
• fiber preparation and card feeding equipment for the two new cards
• more hydraulic power to reliably and efficiently hydroentangle multi-layer webs
• an extension to the dryer for increased evaporation capacity

After starting up in the second half of 2022, Eruslu will be operating an ultra-modern, highly flexible NCR-NCA-NCR spunlace line, the first of its kind in Turkey. The line is tailor-made to process virgin cotton fibers, comber noils and short fibers at high speeds. End products are top-quality, lightweight natural wipes or heavy-weight, three-layer nonwovens for cosmetic pads.

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

• 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.

Flax has accompanied people for thousands of years, in linen fabrics, in ropes, as insulation material. And until the present day. With woven tapes made of flax, vombaur makes the functional and ecological advantages of natural fibres available for lightweight design.

Lightweight and firm
Flax fibres are particularly rigid and tear-proof. Textiles made of the natural material therefore give natural fibre reinforced plastic (NFP) special stability. Additionally, flax has a low density. The components thus combine high rigidity and strength with low weight. Another functional plus: natural fibre reinforced plastics are less prone to splintering than glass fibre reinforced plastics.

Sustainable material
The cultivation of flax binds CO2 and the production of NFP generates 33 percent lower CO2 emissions than conventional fibre reinforced plastics. The energy consumption is 40 percent lower. This reduces production costs and improves the material's CO2 footprint. Punch-packing arguments for natural fibre tapes – like flax tape by vombaur – in lightweight design applications.

Circular Economy
Circular Economy – this also works in lightweight design. The number of recycling cycles without loss of quality is higher for natural fibre reinforced plastics than for glass or carbon fibre reinforced plastics: the thermoplastic matrix of the composite can be melted and recycled after a product life cycle. The natural fibres can "live on" in other products – injection moulded products for example.

Versatile applications
"Composites from our flax tapes are used to reinforce high-tech skis as well as for extruding state-of-the-art window sections – the applications are countless," explains Tomislav Josipovic, Sales Manager with vombaur. "As a development partner, we support applications for the automotive, wind energy, construction, sports and many other industries with our composite textiles."

Technologies with an excellent environmental performance throughout the entire product life cycle – that is what “Autoneum Pure.” stands for. In future, components that meet the highest standards in terms of sustainability and eco-friendliness can be identified at a glance under this label. This also includes the innovation “Mono-Liner” for wheelhouse outer liners.

As innovation leader in acoustic and thermal management, Autoneum continuously invests in the development and production of resource-saving components that make cars lighter and thus more climate-friendly. In view of an increasing sustainability awareness and the correspondingly greater information needs on environmentally-friendly vehicle components, the Company has now launched Autoneum Pure. The label determines particularly sustainable technologies, thereby guiding car manufacturers in product selection for future models.

Autoneum Pure is based on a comprehensive set of criteria assessing the sustainability performance of a product in all four phases of its life cycle: material procurement, production, use and end of life. For example, components with a high content of recyclable materials or those that achieve significant weight savings compared to comparable standard components qualify for the “Autoneum Pure.” label. Autoneum already offers various multifunctional technologies that meet the high standards for Autoneum Pure products: Ultra-Silent for underbody systems or battery undercovers, Di-Light for carpet systems, Prime-Light and IFP-R2 for inner dashes and floor insulators as well as Hybrid-Acoustics PET for e-motor encapsulations and engine-mounted parts, which was launched in fall 2019.

With Mono-Liner, the latest innovation for wheelhouse outer liners is also included in the Autoneum Pure portfolio. Among other things, the Mono-Liner-based components convince thanks to their lightweight construction, thereby contributing to lower vehicle weight with correspondingly less fuel consumption and emissions. The excellent life cycle assessment is also based on their particularly resource-saving manufacturing: Production cut offs of the components, which consist to a large extent of recycled PET fibers, can be processed into pellets and completely returned to the manufacturing process as fibers. An SUV and a crossover model from a US vehicle manufacturer already benefit from Mono-Liner wheelhouse outer liners.

Anahid Rickmann, Head of Corporate Communications & Responsibility, explains: “With Autoneum Pure we are the first automotive supplier to establish a sustainability label in the field of acoustic and thermal management. Autoneum Pure is part of the Company's Advance Sustainability  Strategy 2025 and sets industry standards in product communication.”

For Schoeller Summer 2020 everything flows smoothly. The fabrics move with a fluid lightness in a closed ecological cycle. Upcycled products with ECONYL® yarn and the PFC-free ecorepel® Bio technology based on renewable raw materials are two ecological highlights of the 2020 Summer Collection, which is being developed and produced in the heart of the Swiss mountains. Color effects turn the functional textiles into exciting multicolors with contrasting reverses and fresh, modern plain colors that can easily be combined.

REGENERATED ECONYL® YARN
The textiles manufactured by Schoeller using ECONYL® yarn made from regenerated material are genuine upcycled products. The ECONYL® Reclaiming Program of Aquafil S.P.A. reduces global waste by collecting recyclable materials from landfill sites and the world’s oceans and returning them into the production cycle. The resulting yarn is no different from conventional textiles in terms of quality and appearance. The Schoeller fabric family with ECONYL® yarn encompasses a complete package with diverse exciting qualities such as ultra-light, bi-elastic schoeller®-dynamic (e.g. for windbreaker blousons), very soft, fine schoeller®-dryskin (e.g. for high-tech shorts) and lightweight schoeller®-WB-400.

ECO-CREATED
New, supersoft soft-shells with ECONYL® yarn are available with different backings and weights depending on the situation. The lightest schoeller®-WB-400 radiates a sense of summer in fresh tones such as melon, oxygen blue or khaki with a smooth jersey reverse in contrasting colors, also made from ECONYL® yarn. A slightly heavier quality surprises in classic black with an elegant, navy blue reverse, while the Bordeaux nuance of the soft-shell with its brushed reverse in stone grey feels warm, soft and cozy. The fluorocarbon-free ecorepel® bio-technology, based on renewable raw materials, offers sustainable water repellence.

WHITE MATTER
The dominant features of summer 2020, alongside sustainable textiles and technologies made from natural materials, are inspired multicolors. The comfortable, multicolored schoeller®-WB-400 qualities produce completely new color effects and create a cheerful look – both for outdoor activities and in urban sportswear. The combination of melon, ocean green and stone grey with white changes the mood of the original colors and lends the textiles an unexpectedly chalky, summery look. Another striking feature is the lightweight, white jersey backing, which is only revealed at second glance.

AUGMENTED ORIGINALS
The presentation of the authentic schoeller®-dynamic qualities is no less lively, ranging from mossy green tones and blue nuances through to the brown variations of tree bark. The multicolors combine perfectly with plain fabrics and are impressively functional thanks to the PFC-free ecorepel® bio-technology, which also provides reliable water repellence. The basic qualities of the lightweight schoeller®-dryskin trousers and jackets are given a touch of elegance in the form of a discreet sheen and fashionable colors. In soft blues and greens, these supple all-rounders are highly wear resistant and offer ideal moisture management through the microfibers on the inside. They also feature ecorepel® bio-technology for water repellence.
