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.

• JUMBO-Textil offers elastic high-tech braids – produced on high-tech systems

Developing narrow textile solutions for our customers – quickly, flexibly and precisely – that is our claim. For us and for our technology. Because first-class industrial solutions require first-class technology. Highly automated and digitally controlled. Technology like that found in our variation braider from Herzog – the high-performer among modern braiding machines. JUMBO-Textil is the first narrow textile manufacturer ever to produce elastic hole cords on the special system.

High-performance system for extremely stable textile components
The special system combines sophisticated bobbin lace technology with digital control and thus enables the production of highly complex, individually specifiable braided structures. The variation braider's technology ensures an uninterrupted fibre course across all branches. This not only allows individual, idiosyncratic geometries, it also and above all helps with the stability of the components. This is because where other methods create branching points that are susceptible to breakage due to laser cutting, seams or knots, the variation braider simply braids through the branched strands. As the fibre course is not interrupted in braided branches, the resilience of the textiles is significantly increased. And individual braids are created for very different applications.

Bobbin lace technology for highly complex structures
Unlike in classical braiding systems, the impellers of the variation braider are arranged in a square. Up to eight different strands can be braided and interlaced with the textile all-rounder. All bobbins can be programmed separately and thus the bobbin lanes can be combined variably and individually. JUMBO-Textil also produces tubular braids with precisely defined braided openings, triaxial braids and highly complex preforms with the variation braider. The geometries of the narrow textiles range all the way to net structures. For braided cables, we create stable connections in the core-sheath braiding by weaving the core and the protective sheathing, which provides protection especially at the turns: there is no longer any undesired core and sheath slippage.

Individual braid architectures – for automotive, outdoor and more
Complex non-elastic cords from the variation braider have been in operation at JUMBO-Textil for a long time. For hole cords – or bifurcation cords (from the Latin: furca, the fork) – the bobbin points are individually programmed so that the arrangement and length of the branching precisely meet the requirements. It is used, among others, in the automotive sector, in the construction industry and in the outdoor sector to hang or unhang elements without using metal.

Elastic hole cord from the elastics specialist
The elastic hole braids by JUMBO-Textil are new on the market. "The variation braider offers us fantastic possibilities: we can pre-configure what we want to braid and are completely free to do so. The repeat is computer-controlled," explains Holger Vehring, Project Engineer at JUMBO-Textil. "A seamless braided cable harness tubular that organises the cable mess (for automotive), braided hoses with defined openings for conductive elements in smart textiles or rehab applications, as tensioning elements in backpacks or functional clothing – the possible applications are vast. Thanks to this technology, textile – i.e. lighter, quieter and more flexible – components can be used for numerous applications in which metallic materials were previously used due to the fragile branching points."

• At this year’s INDEX from October 19th to October 22nd, Truetzschler Nonwovens, Truetzschler Card Clothing and Voith introduce new solutions for manufacturing a broad range of sustainable nonwovens for wipes, hygiene or medical textiles at booth 2327.

Plastic-free initiatives worldwide affect everyone: consumers, product developers, nonwoven producers and finally nonwoven machinery suppliers.

Truetzschler Nonwovens and Voith address the quest for more sustainable and affordable nonwovens in the wipes segment by two proven technologies for manufacturing pulp-based nonwovens. Firstly, WLS (Wet-Laid/Spunlaced) lines. More than a handful are in service worldwide and mainly target the flushable wipes market. At INDEX we’ll introduce our latest nextLevel/WLS baby and body wipes, a joint development by Voith and Truetzschler.

The second focus is on carded/pulp (CP) products. A CP line – including a TWF-NCT card placed between the HydroFormer and the AquaJet is already running to full capacity at customer site. Various CP materials, including innovative nextLevel/CP wipes, will be on display at the booth and invite visitors to discuss characteristics, benefits, line concepts and equipment.

When talking sustainable nonwovens, solutions for efficiently manufacturing biodegradable nonwovens from virgin cotton fibers, comber noils and viscose/lyocell fibers must not be missing. Visitors can look forward to directly comparing cotton nonwovens to a broad range of cellulose-based material.

Truetzschler Card Clothing, our in-house competence center with respect to card clothings and comprehensive service, presents its latest development, the Z wire for high-speed roller cards. A new geometry minimizes fiber fly and allows for better carding and more stable web forming.

Notus Composites (UAE), the award-winning producer of epoxy prepreg materials, announces the latest addition to its high-performance epoxy range with the launch of its new NE7 low temperature curing prepreg system. The Notus NE7 formulation allows composite manufacturers to cure components at temperatures as low as 70˚C, reducing energy consumption and enabling more cost-effective tooling options.

Notus Composites has developed the new NE7 prepreg systems for applications across the Marine, Architecture, Industrial and Wind Energy sectors, with the novel low temperature curing chemistry delivery significant cost benefits. Existing prepreg manufacturers can now use more cost-effective composite tooling, with new prepreg users able to switch easily from existing infusion or wet laminating processes without creating expensive new high temperature tooling.

NE7 prepregs can be cured at temperatures as low as 70˚C, with the standard cure cycle being 12 hours at 70˚C, matching the typical cycle time for an infused part with a component Tg of 85˚C. NE7 materials have a good outlife of 30 days at 20˚C and are available in all prepreg and Notus single sided N1-Preg formats with unidirectional, multiaxial, and woven reinforcements. NE7 can also be supplied as a resin film.

Notus has recently supplied NE7 low temperature prepregs to Dubai based Aeolos Composites for the production of their new Aeolos P30 racing yacht. The P30 is a futuristic new craft created by top German sailor and designer, Hans Genthe, with a super light carbon fibre construction and large sail area that promises spectacular on the water performance for a thirty foot yacht. Notus delivered a range NE7 prepregs for the build, including woven, multiaxial, and unidirectional carbon fibre reinforcements as well as adhesive films for core bonding.

Swiss dairy company Emmi is partnering with Borealis and Greiner Packaging to produce iced coffed drinking cups using chemically recycled polypropylene.

The cups are produced by Greiner Packaging and the chemically recycled material comes from Borealis, one of the world’s leading providers of advanced and circular polyolefin solutions based in Vienna, Austria.

Emmi, Switzerland’s largest milk processor is committed to climate protection and the circular economy. The dairy company has the stated goal to make all of its packaging 100% recyclable and is committed to various measures to promote circularity such as packaging that contains at least 30% recyclate by 2027.

From September 2021 Emmi will use at least 100 tonnes of plastic based on the recycled material each year. Chemical recycling renews plastic back to plastic creating recycled materials with a level of purity equivalent to fossil-fuel based PP and hence, fit for protective, food-safe and other demanding applications. In this way, Emmi is utilizing difficult to recycle feedstock preventing plastic waste that would be likely landfilled or incinerated. In the future, depending on the availability of suitable material, the amount of recycled plastic in packaging is to be further increased.

The new technology to recover the polypropylene is currently still in its infancy, where Greiner Packaging and Borealis are leading the way. Only limited quantities of chemically recycled polypropylene are currently available, and Emmi is one of only a few food manufacturers to have secured a share of the chemically recycled polypropylene plastic through its early commitment and long-standing collaboration with the development companies.

The chemically recycled material used for the cups consists entirely and solely of ISCC (International Sustainability & Carbon Certification) material, on a mass balance basis. Mass balance is a methodology that makes it possible to track the amount and sustainability characteristics of circular and/or bio-based content in the value chain and through each step of the process. This provides transparency ultimately also to the consumers, enabling them to know that the product they are buying is based on this renewable material.

There has been a sharp rise in demand for organic cotton products. Compared to conventionally grown cotton, the cultivation of organic cotton requires the renunciation of genetically modified seeds, chemical pesticides or fertilisers. Nevertheless, genetic modifications are repeatedly found in textiles that are falsely labelled with organic claims. Often, available certification systems are not backed up by lab testing. At best, they only take random seed samples. Textile testing specialist, Hohenstein, has developed an assessment method specifically for cotton. This new DNA analysis method makes it possible to ascertain the amount of genetically modified cotton contained in products. This is good news for textile industry stakeholders who will be on the safe side in terms of quality control and labelling of organic cotton products.

First step: qualitative screening and identification. Second step: quantification of genetically modified cotton.
For qualitative screening, Hohenstein experts had developed molecular biological detection systems to make clear yes/no statements about genetically modified cotton. Testing can be applied to all kinds of materials, from raw cotton to chemically untreated yarns and fabrics. In addition, Hohenstein is one of only a few laboratories in the world accredited to test for GMOs in accordance with the ISO/IWA 32:2019 protocol. Its method provides reliable evidence of the presence or exclusion of genetic modification in cotton textile precursors.

Once qualitative proof of genetic modification is obtained, Hohenstein experts begin quantifying the type and extent of the genetic modifications. To do this, they use DNA analysis to search for different cotton lines known to contain genetic alterations and quantify the proportion. Only by pinpointing individual genetic modifications and quantifying the extent of modification is it possible to provide precise information on whether there is an extremely small proportion of contamination, or whether larger proportions of GMOs have been mixed in. This offers clear benefits to manufacturers, brand owners and retailers when it comes to supply chain transparency and fraud prevention.

• Harmonized Language Increases Efficiency to Communicate Globally Consistent Descriptions, Production and Testing

EDANA and INDA, the leading global nonwovens associations, jointly announce the launch of the 2021 edition of standard procedures for the nonwovens and related industries.

These Nonwovens Standard Procedures help technically define the nonwovens industry, with specifiers for the properties, composition, and specifications of its products. Offering harmonized language for the industry across the USA and Europe, and recognized by many other individual markets, the procedures offer a way for the nonwovens industry to communicate both across the globe, and within the supply chain to ensure that product properties can be consistently described, produced, and tested.

The harmonized methods contained in the Nonwovens Standard Procedures (NWSP) edition include 107 individual test procedures and guidance documents to support applications across the nonwovens and related industries, and are available on both www.inda.org and www.edana.org.

The 2021 edition includes updated or modified procedures with a numbering structure that makes the document intuitive to search and use. Additionally, each method also includes a page to summarize and track relevant changes made to the document. In an effort to make all methods more consistent, each one is now presented in a format building on the International Standards Organisation (ISO) template, facilitating any future possible submission to ISO in an effort to become a recognized international standard or technical specification.

As in previous editions, the table of contents for the Nonwoven Standard Procedures document includes references to existing related ISO standards, which makes it easier for technicians to choose the most relevant procedure or methods to apply to their product.

Hexcel, a global leader in advanced composites technologies, confirms that its HexPly® M901 prepreg system has been selected by Rassini, a Mexico-based technology leader in composite vehicle suspension systems, to speed up prototype and new product development cycles, reducing overall time to market with an easy to process material solution that enables effective early-stage design screening and cost-effective production.  

As a specialist in the mass production of composite helper leaf springs for various leading OEMs, Rassini continuously develops innovative new suspension component designs. Due to cost and timing, however, these new products cannot easily be prototyped using conventional high-pressure resin transfer molding (HP-RTM) technology.

With more than 15 years of experience in delivering glass fiber prepregs for the serial production of composite leaf springs, Hexcel developed its high-performance HexPly M901 prepreg system specifically for this type of application. HexPly M901 combines the right level of structural performance required with simple processing, providing Rassini with a reliable material solution optimized for rapid development and fine-tuning iterations.

HexPly M901 is a high Tg epoxy resin prepreg system specifically developed for structural components that will be exposed to harsh thermal and environmental conditions.  With short cure cycles of 10 minutes and below producing excellent green, or handling, strength of the composite part for demolding and unidirectional glass fiber aerial weights up to 1,600gsm, HexPly M901 delivers a powerful combination of benefits for suspension component applications.

Iluna Group comes back to Milano Unica with a great and important goal: to relaunch the qualities and dimensions of sustainability by going beyond the ingredient.

Iluna’s new path, which was born in a moment when the market seems to speak about “fragility”, begins with the investment in the renewal of machines, which allow it to fly ever higher in terms of high-tech developments, quality, definition, effects of yarns and patterns. The journey into the new dimension of responsible quality continues with ad hoc developments in the field of GRS (Global Recycled Standard) certified recycled yarns, aimed at unprecedented effects both in look, in performance and in the hands of fabrics. Including cord yarn, shiny threads and an expansion of the range of GRS yarns, previously available only opaque. The cord yarn is a precious yarn with a ROICA™ EF premium stretch yarn core, GRS certified and developed with 50% of pre-consumer waste materials content - double, covered with an equally recycled shiny thread; the bright and translucent is instead to add brilliant effects so far not possible with a GRS yarn.

The printing processes are also born from this constant search for innovation towards new materials and new techniques, becoming more and more sustainable: Global Recycle Standard (GRS)-certified sublimation printing and register printing carrying Global Organic Textile Standard (GOTS) certification. This one overlap exactly on the design and color the details, reaching where the dye cannot reach.

Diversification has become essential in today’s competitive market and the fragility of the moments experienced in 2020 was the stimulus to return to being here again, to return to action. Flexibility is the watchword today, along with research. And Iluna has managed to go further: starting from the ingredients at the base of the materials, last year launched a collection with natural dyes made with GOTS certified plant-based dyes, up to proposing magnificent prints with extraordinary effects for this edition of the Milanese fair.

The three dimensions of sustainability, design and innovation are thus finally linked thanks to valuable partnerships with expert and excellent reference companies that have allowed these new developments and these unique results thanks to advanced technologies designed specifically for Iluna, which is today the only company to offer ingredients, natural colors and prints, all three strictly certified.
