• Composites in the construction industry - The lightweight construction material of the future

Building with fibre-reinforced materials opens up completely new possibilities. In terms of engineering, design, and organisation. This is due, on the one hand, to the excellent properties of fibre-reinforced materials (FRM) and, on the other hand, to the fact that the material – unlike wood or brick, for example – is not machined or processed for its use, but custom-produced.

Excellent properties – in terms of engineering, design, and organisation
Fibre-composite materials offer a whole range of technical properties for innovative and sustainable building:
•    High mechanical rigidity
•    Low weight
•    High corrosion resistance
•    Low material fatigue
•    Low heat transfer coefficient of the plastic matrix
•    Resistance to frost and de-icing salt
•    Good draping capability

In addition, fibre composites offer numerous design options for novel and exceptional new building and maintenance projects:
•    Unique variety of shapes
•    Different structures of the textiles
•    Large spectrum of colours and colour combinations
•    Translucency of the plastic matrix
Thanks to these properties, composites can be used to produce coloured, phosphorescent, thermochromic or – through the use of LEDs or light-conducting fibres permanently integrated into the matrix – luminescent components.

In addition, there are organisational benefits for planning, construction and maintenance work with fibre-reinforced materials:
•    Easier handling and assembly of the far lighter and more flexible components – compared with steel, concrete or wood
•    Faster installation
•    Shorter construction site times in road and bridge maintenance
•    Shorter delivery times
•    Ability to integrate electronic monitoring systems

Individual composite textiles – for every lightweight engineering project
The composites experts at vombaur develop and manufacture woven tapes and seamless round or shaped woven textiles from carbon, glass, flax or other high-performance fibres on special weaving lines for individually specified round and shaped woven textiles – and can therefore offer you the best possible fibre base for every lightweight construction project.

"Regardless of whether it's a new construction or a renovation project, a façade design, a bridge or a staircase – as your development partner for composite textiles, we have plenty of experience with composites for demanding tasks," emphasises Dr.-Ing. Sven Schöfer, Head of Development and Innovation at vombaur. "We develop, create samples and manufacture woven tapes and seamless round or shaped woven textiles – in collaboration with the customer 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 projects.

• 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.

• From fossil to renewable materials: Members advocate policy analysis and focused implementation of the renewable carbon strategy

The members of the Renewable Carbon Initiative (RCI) (www.renewable-carbon-initiative.com), founded in September 2020, have joined forces to shape the transition from the fossil to the renewable age for the chemical and materials industry. This means spreading the concept of renewable carbon and developing new value chains based on renewable carbon as a feedstock.

In the meantime, several activities have started from which future members can benefit as well. First and foremost is the kick-off to comprehensive policy analysis. What influence will forthcoming regulation have on chemicals, plastics, and other materials? When and where should the renewable carbon idea be emphasized and referred to?

The policy analysis will examine pending policies in the European Union – and a later expansion to America and Asia is planned as well.

A particular focus will be placed on upcoming policies and regulations and how they impact renewable carbon. The members are currently deciding on where to start specifically, but questions that may be considered are: What does the new climate law and the “Fit for 55-Package” mean for chemicals and materials? What can be expected from REACH and microplastics restrictions? How relevant is the “Sustainable Products Initiative” and the coming restrictions for Green Claims? Circular Economy, Zero Pollution and Sustainable Financing are keywords of the future European landscapes, which might become very concrete for chemistry and materials in the next few years. To what extent the concept of renewable carbon for materials is considered in policy already and how it could be further introduced in future legislation are two of the main questions investigated in the working group “Policy”.

This working group is open to all members of RCI. Policy experts provide the respective analysis as a foundation, organising discussions between members of the policy group and plan meetings with policymakers to introduce the Renewable Carbon concept.

Additional working groups have been created, one with a focus on communication, the other looking at the development of a renewable carbon label. In early September, a renewable carbon community will be launched as a starting point for even more interaction between the members, to discuss strategies, create new value chains and start project consortia.

The Renewable Carbon Initiative (RCI) is a dynamic and ambitious group of interested parties. Membership numbers have now more than doubled since the launch almost a year ago, with RCI now boasting 25 members, 6 partners and over 200 supporters. It welcomes all companies that are on the way to transform their resource base from fossil to renewable.

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.

ISKO, a global, leading premium denim ingredient brand, announced its participation in The Jeans Redesign – a project, established by the Ellen MacArthur Foundation’s Make Fashion Circular initiative, to encourage and guide the denim industry to transform the way jeans are made and move towards a circular economy for fashion.

ISKO’s R-TWO™ is the embodiment of its Responsible Innovation™ mindset and aligns with the principles of a circular economy espoused by the Ellen MacArthur Foundation – to ensure durability, material health, recyclability and traceability. R-TWO™ positions ISKO as a sustainability leader and enables it to exceed the project guidelines to create denim that is designed to be used more, made to be made again and made from safe and recycled or renewable inputs.

International technology Group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at ANEX/SINCE 2021 in Shanghai, China, from July 22 to 24, 2021. The product portfolio covers state-of-the-art nonwovens and textile production technologies such as air-through bonding, needlepunch, spunlace, spunbond, wetlaid/Wetlace, converting, textile finishing, airlay, recycling, and bast fiber processing.

Among the largest end-use markets for nonwoven products are materials for durable uses. Interior linings for cars, materials for construction, geotextiles, synthetic leathers for clothing and furniture, carpeting, filtration and many other industries rely on the use of nonwovens produced using the needlepunch method.

ANDRITZ Nonwoven’s processes play a pioneering role in the production of biodegradable materials. For many years, ANDRITZ has offered different processes, like spunlace, Wetlace and Wetlace CP, all with one goal in mind: Elimination of plastic components while maintaining the high quality of the desired product properties. Such processes achieve high performance entirely with plastic-free raw materials. The added benefit of using a blend of fibers, like wood pulp, short-cut cellulosic fibers, viscose, cotton, hemp, bamboo or linen, without chemical additives results in a 100% sustainable fabric, thus meeting customers’ needs exactly as well as supporting the strong tendency to move away from plastics and synthetics.

The latest development in this field is the ANDRITZ neXline wetlace CP line. This process combines the benefits of two forming technologies (inline drylaid and wetlaid web forming process) with bonding by hydroentanglement. Natural fibers, like pulp or viscose, can be processed smoothly and generate a high-performance and cost-efficient wipe that is fully biodegradable and plastic-free.

Sappi is expanding its product range for corrugated board applications with Fusion Nature Plus.

With Fusion Nature Plus, Sappi is launching an uncoated, fully bleached and completely recyclable virgin fibre liner. The company provides a unique variety of packaging and speciality papers. The specialist in paper-based solutions also offers a wide range of products in relation to labels. Fusion Nature Plus offers excellent printing results in flexographic, digital and offset printing processes.

• Ultra-bright, uncoated virgin fibre paper with excellent printing results
• Ideal for attractive corrugated board as well as premium shopping bags
• Can be used as topliner, liner or fluting
• Available in grammages of 80 to 130 g/m²

The virgin fibre liner is based on the concept of the successful Fusion Topliner. In contrast to the double-coated Fusion Topliner, Fusion Nature Plus has a natural, uncoated surface with a more tactile feel, in response to the growing market appetite for this type of product. The liner is also provided in very low grammages.

Fusion Nature Plus enhances brand appearance

Brand owners, corrugated board processors, manufacturers of display cartons and folding cartons as well as designers all benefit from the versatility of the new Fusion Nature Plus. In contrast to conventional uncoated liner papers, the material offers high brightness, brilliant colour reproduction and consistently high quality. These features make the product the perfect choice for corrugated board or solid board packaging, where a very bright appearance is needed for topliners, inner liners and corrugating applications. Whether used as an inlay in cosmetics or confectionery packaging, or as a liner in shipping packaging to ensure an exceptional unboxing experience, Fusion Nature Plus is called upon wherever an enhanced appearance is desired.

Another area of application is paper carrier bags, where uncoated paper qualities are often preferred.

Fusion Nature Plus is ideally suited to a range of printing processes: the product achieves outstanding results in flexographic and offset printing. The pre-treated surface and high brightness offer clear advantages with regard to primer requirements and print behaviour, especially for inkjet-based digital printing. Bernd Gelder, Head of Sales Containerboard at Sappi Europe: ‘With its exceptional print quality and impressive colour reproduction, Fusion Nature Plus particularly appeals to packaging customers who value a natural look and feel in paper. The response from the market, in which packaging based on corrugated board still needs to take on a bigger role, is enormous, of course, with the result that we have succeeded in completing a number of interesting end applications and customer projects with Fusion Nature Plus shortly after market launch.’

Virgin fibre vital for recycling

In continuous recycling use, fiber that has already been recycled is subject to a progressive weakening of quality, resulting in a weakness in the products that incorporate them, but also, crucially, over time they will ultimately degrade to a point where they become unrecoverable. As a result, a certain amount of virgin fibre needs to be introduced into the cycle on a regular basis. Without continuous virgin fibre contribution to the pulp cycle, recycled producers will in the end run out of raw material. The premium virgin fibre liner Fusion Nature Plus from Sappi plays an important role here in maintaining the quality of the recycling substrate.

Thanks to the central location of Sappi’s production site in Ehingen, Fusion Nature Plus can be supplied quickly throughout Europe. The shorter transportation distances reduce transport related fossil emissions and protect the environment. The shorter production cycles in turn ensure high availability and rapid supply.

Fusion Nature Plus is currently available in six grammages from 80 to 130 g/m² in both sheet and roll form. Sappi can also provide Fusion Nature Plus with FSC or PEFC certificates on request.

Reinach, Switzerland, and Westlake, Ohio, 2 February 2021 - Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced a strategic partnership with technology innovator CleanKore, aiming to advance sustainable dyeing processes throughout the denim supply chain.

The agreement will allow Archroma and CleanKore to promote the benefits of each other’s technologies. This includes Archroma’s robust catalog of dyes and specialty chemicals along with CleanKore’s patented process of dyeing yarns at the denim mill that completely eliminates the need for potassium permanganate (PP) spray and laser booster to achieve the bright white abrasion effect in the garment finishing process. The result is a large and circular bright white core with a small ring of indigo dye. The technology does not just eliminate the chemicals associated in the PP spray and laser process, which is much safer for denim workers, it also allows to save significant amounts of water and energy throughout the manufacturing process from fabric to garmenting.

CleanKore initially looked at eliminating potassium permanganate due to its being classified as hazardous if inhaled or ingested, or in case of contact with the skin or the eye. It is also considered very toxic to aquatic life. No new equipment or capital expenses are needed to implement the CleanKore technology, which works on all denim fabric, including dark indigo, sulfur top/bottom and sulfur black.

This is where Archroma comes into the picture. Its global technical team of denim coloration specialists will provide support to denim mills seeking to implement the CleanKore technology and develop the desired looks and effects - with the right colors and chemical systems for their production set-up.

CleanKore estimates that the technology allows to save up to 15 liters of water per garment, or the equivalent to the drinking needs of 5 people per day, and up to 0.51 kWh of energy per garment, or the equivalent of five 100-watt light bulbs on for 1 hour. The CleanKore technology also leads to a 10% to 20% increase in production throughput, as a result of a faster garment wash-down and the elimination of PP spray.

For CleanKore CEO Darryl Costin Jr., the announcement comes at an ideal time for CleanKore: "We have successfully proven the technology with mill partners such as Arvind and other denim mills in Pakistan, Bangladesh, China, Vietnam, Thailand and the United States. The response from the industry has been overwhelmingly positive. Having a partner in Archroma, one that is highly respected for their innovation and emphasis on sustainability throughout the industry, will allow us to take CleanKore to the next level.”

Umberto Devita, Global Indigo Manager at the Archroma Global Competence Center for Denim & Casualwear, adds: "CleanKore is perfectly aligned with the 3 pillars of 'The Archroma Way to a Sustainable World: Safe, efficient, enhanced'. 'Safe' through the elimination of a potentially harmful substance and the protection of the denim workers, 'Efficient' through the reduction of resource consumption, improved productivity and cost-effective profile. And 'Enhanced' through the gorgeous colors and effects allowed with Archroma's innovations and systems, in particular our aniline-free* Denisol® Pure Indigo and Diresul® sulfur dyes. We look forward to help promoting an innovation that will help with many of the challenges facing our denim customers throughout the world. Because it’s our nature."
