• Innovations in Recycling and Sustainability: Sustainable Diaper Components, Natural Fibers, and Kitty Litter from Recycled Nappies

INDA, the Association of the Nonwoven Fabrics Industry, announced the three finalists that will present their innovative material science solutions as they compete for the prestigious RISE® Innovation Award during the 12th edition of the Research, Innovation & Science for Engineered Fabrics Conference (RISE®) to be held in person September 27-28, 2022 at North Carolina State University.  The award recognizes novel innovations within and on the periphery of the nonwovens industry that creatively use next-level science and engineering principles to solve material challenges and expand the usage of nonwovens and engineered fabrics.

Finalists for the 2022 RISE® Innovation Award:
Cat Litter Made from Recycled Nappies – DiaperRecycle
DiaperRecycle has developed technology to recycle used diapers into cat litter. The aim of the company is to make an environmental impact and decrease the climate changing emissions of diaper waste. They’re diverting used diapers (used in households and businesses such as elder care) from landfill, separating the plastic and fiber and making cat litter. The plastic is prepared for recycling by plastics recyclers. The cat litter product is made by DiaperRecycle from the super absorbent fiber of diapers; it’s highly absorbent and flushable.

Biodegradable Diaper Components – Gottlieb Binder GmbH & Co. KG
Together, Avgol and Binder take on the challenge of disposable absorbent articles for the good of future generations and came up with sustainable diaper components. The technologies used are based on biotransformation technology, which makes it possible to achieve more sustainable products by supporting recycling and providing an alternative route for non-recyclable/fugitive waste management.

sero® hemp fibers – Bast Fibre Technologies, Inc.
Bast Fibre Technologies’ sero® hemp fibers offer the nonwoven industry an all-natural substitute for plastic fibers. From dedicated European- and US-based production facilities, BFT transforms raw bast fibers into premium natural fibers for applications ranging from single-use and durable wipes to industrial applications. Suitable for minority or majority blends, sero® hemp combines easily with standard nonwoven fibers to produce fabrics that meet the industry requirements for strength, uniformity, and processing efficiency.

• Collaboration with Red Points addresses consumers’ increasing expectations on transparency and highlights Lenzing’s commitment to trademark protection
• Protects interest of Lenzing customer and partners who are making real efforts to enhance the transparency of their value chains
• Builds upon Lenzing’s overall brand protection efforts that verify the authenticity of fibers up to the end products

Lenzing Group, a global producer of wood-based specialty fibers, has announced a partnership with Red Points, a company in online IP infringement detection and removal, to strengthen Lenzing’s existing brand protection efforts globally and enable round-the-clock brand monitoring services. As Lenzing’s textile brands TENCEL™, LENZING™, ECOVERO™, as well as nonwovens brand VEOCEL™ continue to generate widespread demand from industry partners and customers worldwide, it is becoming increasingly important to protect the company’s trademarks and provide full visibility into the brands’ presence online.

Protecting the interest of Lenzing’s partners and consumers
Red Points provides the ideal technology solution to help Lenzing monitor and remove unauthorized use of its trademarks and counterfeits online. The technology works by using Artificial Intelligence (AI) to automatically detect intellectual property infringements of Lenzing’ trademarks with high accuracy and efficiency.

Brand protection is just one of Lenzing’s ongoing proactive measures aimed at enhancing transparency in the supply chain and protecting the interest of Lenzing’s partners by ensuring they are purchasing genuine Lenzing fibers which meet their high standards.

In 2018, Lenzing launched the Lenzing E-Branding Service which allows Lenzing’s customers, retailers and brand partners to effectively use trademarks in their marketing materials. The platform has been welcomed by partners globally as it continues to deliver value to the fashion, textile and nonwoven sectors by facilitating the traceability of Lenzing’s fibers and enabling customers to promote them effectively.

The recent Techtextil show in Frankfurt emphasised the diversity of applications for nonwovens and technical textiles, according to finishing technology specialist Monforts.

“We fielded enquiries at top management level from an extremely wide range of companies, all with very different ideas for new product applications during the show,” said Alexander Fitz, who joined the company a year ago as engineer for textile technologies and co-ordinator of the Monforts Advanced Technology Centre (ATC). Fitz brings a background in both technical textile technology and processes to the role, having previously worked for a nonwovens machinery builder and a roll-goods manufacturer.

Trials
“We are now looking forward to interesting new trials and pilot production runs, as well as the commissioning of new orders for machines resulting from the extremely busy exhibition,” he says. “Obviously, everyone at the moment is looking to make energy savings, and we have developed a range of options for helping companies increase their resource efficiency, both on new lines and as retrofitted systems, but this is not stifling innovation at the new material level.

“There was a lot of interest in what is possible with the Montex®Coat coating system and the range of different techniques it enables, and at our ATC in Mönchengladbach, a Montex®Coat unit is integrated into the full technical textiles pilot line, on which it is possible to run new fabrics in widths of up to 1.8 metres.”

Explosion proof
The technical textiles line at the ATC incorporates a Montex four-chamber stenter and is fitted with an explosion-proof coating application chamber in order to allow treatment to be carried out with organic solvents and other volatile materials.

Every single component within the chamber has to meet the standards of the European Union’s ATEX directives for working in a potentially explosive atmosphere. A range of sensors linked to alarms operate at various levels within the chamber to ensure the specified lower explosion limit (LOL) is never exceeded and the ventilation adapts accordingly.

Advanced functions
Special features on the finishing line relate to further advanced functions such as the ability to treat materials not only at temperatures of up to 320°C, but also to be able to treat the top and bottom faces of certain materials at different temperatures within a single pass through the machine.

To achieve this, the first two chambers of the stenter are fitted with special, heavy duty TwinAir ventilation motors and separate burners for individual top/bottom temperature. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment paramenters.

Another key feature of the technical textiles line at the ATC is the special stretching device which is capable of pulling ten tons in length and ten tons in width – a huge amount per square metre of fabric and necessary in the production of materials such as woven or 3D knits for high temperature filter media.

• The Borvida™ portfolio introduces sustainable base chemicals to Borealis’ range of product offering
• The range will initially be based on non-food waste biomass, and chemically-recycled waste; in the future it will also draw from atmospheric carbon capture
• The traceability of the content will be based on Mass Balance, which is ISCC PLUS certified
• This is the next step in an ambitious sustainability journey, which will see Borealis move away from traditional fossil-based feed

Borealis is strengthening its EverMinds™ circular product offering with Borvida™, a range of sustainable base chemicals.

The Borvida portfolio will offer base chemicals or cracker products (such as ethylene, propylene, butene and phenol) with ISCC Plus-certified sustainable content from Borealis sites in Finland, Sweden and Belgium. The move is part of Borealis’ broader commitment to a Future-Positive Revolution, in which the unrivalled benefits of base chemicals and polymers can be enjoyed at minimal impact to the planet.   

The portfolio will initially comprise Borvida B, from non-food waste biomass, and Borvida C, from chemically-recycled waste. In the future, the range will evolve to include Borvida A, sourced from atmospheric carbon capture. Borvida is complementary and is the building block to Bornewables™, a portfolio of polyolefins based on renewably-sourced second generation feedstocks, and Borcycle™, which offers circular polyolefins produced from mechanically- and chemically-recycled plastic waste.

Borealis produces a wide range of base chemicals for use in numerous industries based on various feedstock, such as naphtha, butane, propane and ethane. Through its olefin units (steam cracker and propane dehydrogenation), it converts these into the building blocks of the chemical industry: ethylene, propylene and C4 hydrocarbons (butylenes, ethyl tertiary-butyl ether (ETBE) and butadiene), and C5-6 hydrocarbons (pygas, phenol) among others.

The basis of the Borvida portfolio is Mass Balance, a Chain of Custody model that enables sustainable content to be tracked, traced, and verified through the entire value chain, offering sustainability-assured products from feedstock to end product. Using this model, circular alternatives can be offered in a cost-effective and environmentally-conscious way, which can be scaled up quickly without compromising on quality or efficiency.

Borvida can be used for a wide range of different polymer and chemical applications, also beyond polyolefins (PO). Non-PO polymers, such as polycarbonates, acrylonitrile butadiene styrene (ABS), super absorbant polymer (SAP) and other chemicals, are utilised for various end applications including coatings, plasticizers, adhesives, automotive, electronics, lubricants, detergents, appliances and sports equipment.

Together with key strategic partners, including Neste and Covestro, Borealis strives to provide a long-term solution in order to allow value-chain partners to meet their sustainability goals. Borvida will enable our customers to increase the sustainability of their products, keeping them ahead of forthcoming legislative changes, and meeting their customers’ demands for climate-conscious products.

Introduced on a smaller scale in early 2020, early renewable base chemicals customers include Covestro. “The use of alternative sustainable raw materials is one important pillar of our strategic ambition to become fully circular”, comments Frank Dörner, Managing Director Covestro Procurement Services GmbH & Co. KG. “The new product line is a good example for joint solutions, another strategic pillar, in order to establish new and reliable supply chains creating benefits for our customers.”

• Joining Science Based Targets initiative

ith its Advance Sustainability Strategy 2025 launched in 2018, Autoneum defined ambitious goals in the areas of environment, society and governance. In the past year, significant quantitative and qualitative improvements were achieved, as shown in the Corporate Responsibility Report 2021 published today. For example, CO2 emissions were reduced in 2021 and the proportion of reused production scrap (recycling) was significantly increased.

Following Autoneum’s decision last year to extend its environmental targets with quantifiable targets for all direct and indirect greenhouse gas emissions and a time horizon to 2027, the Company has recently signed the declaration to join the Science Based Targets initiative (SBTi). Autoneum acknowledges the urgent need for action and will submit its ambitious, science-based targets to the SBTi to reduce CO2 emissions in the near term. In addition, Autoneum is reporting its Scope 3 emissions in full for the first time. In line with the strategic goal of continuously reducing electricity purchases from fossil fuels and replacing them with renewable energies, ten plants worldwide were converted to renewable energies in 2021.

In the past year, Autoneum again implemented a large number of projects in the areas of “Sustainable Products and Production Processes”, “Fair and Attractive Workplace”, “Good Corporate Citizenship” and “Responsible Supply Chain Management”: 29 eco-efficiency projects with a focus on materials efficiency and recycling contributed to more environmentally friendly production and correspondingly more sustainable components worldwide. The result was a significant reduction in waste and a further optimization of processes for a range of products. Moreover, new eco-efficient products were successfully launched on the market.

A complete overview of all targets and activities during the past year can be found in the Corporate Responsibility Report 2021.

With the purchase of the latest technology, iSAVER® by Itema, in weaving machines, ISKO pushes the envelope of technological performance and sustainability, making further progress in product and process efficiency.

This decision is an additional, important asset in ISKO’s journey towards a genuine Responsible Innovation™. It is part of other crucial investments made by the company, aimed at further reducing its environmental impact, among which stand out R-TWO™50+ – a new denim generation made with a minimum of 50% pre- and post-consumer recycled blend – and the Green Machine – a pioneering technology providing a 100% post-consumer recycling solution that fully separates and recycles cotton and polyester blends at scale.

After an intensive process, a selection was made where ISKO focuses on the development of technical solutions that enable greater resource savings and more sustainable production methods, always with the protection of workers at heart.

As a result, ISKO’s Headquarters extend the company's long-term relationship with Itema,
strengthening the company’s position as the mill with one of the world’s largest denim capacities. The new rapier machines are enhanced by the iSAVER® technology, a breakthrough mechatronic innovation that eliminates the waste selvedge on the left side of the fabric, allowing for saving in energy and raw materials, cutting in half the cotton waste that typically results from the weft yarn. All types of ISKO’s innovative fabrics, with a multitude of different constructions and fiber mixtures, can now be produced using these advanced weaving technologies, with a special focus given to the R-TWO™ technology in terms of its sustainable credentials.

A boundary-pushing approach to hacking carbon reduction challenges has been established by AkzoNobel and partners from across the extended value chain following the company’s first ever global Collaborative Sustainability Challenge.

During 24 hours of intense discussion at the pioneering event a series of high impact exploration teams was set up. Those involved will now continue to work together in a determined effort to collectively accelerate the reduction of carbon emissions in the paints and coatings industry.

The participants – represented by senior and next generation leaders – hacked four key areas: energy transition, process efficiency, solvent emissions and circular solutions. It resulted in 27 partners signing up, including suppliers, customers and end-users, as well as representatives from finance, government, service providers and consultancies.

AkzoNobel has set science-based sustainability targets to halve its carbon emissions across the full value chain by 2030. Achieving that ambition will rely heavily on collaborating with partners and challenging each other to find innovative ways to overcome the unprecedented challenges everyone faces.

The DiloGroup informs at Techtextil in Frankfurt (June 21 – 24, 2022) about new developments aimed at improving production technologies with a focus on needlefelts.

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

1. Intense Needling
   Needling per se is a mechanical production method with a high energy efficiency. For this reason, the development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
   Despite the prospective advantages of the mechanical intense needling method over the hydrodynamical, water entanglement is at the moment the most important production method for low area weights and highest production capacity and is also offered by the DiloGroup as general contractor in cooperation with partner companies.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses; but there may also be potential for increasing uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

Leading knit solutions provider SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its U.S. subsidiary SHIMA SEIKI U.S.A. INC., will participate in the Techtextil North America exhibition in Atlanta, Georgia, U.S.A. this month. Under the theme “techKNITians—Technical Engineered Knit Applications,” the company will display its latest computerized flat knitting machines and computer graphic design system technology, aimed at promoting knitted applications in the field of technical textiles.

Pioneered by SHIMA SEIKI, WHOLEGARMENT® knitting technology is capable of producing knitted items in their entirety without the need for sewing, and allows complex 3D forms to be knit such as car seat covers and interior furnishings. Selective compression allows control over placement and amount of pressure for various compression wear in sports and medical applications. The seam-free nature of WHOLEGARMENT® also ensures continuity of yarn, allowing functional yarns such as conductive yarns to wrap around the entire body without interruption, for applications in smart garments and wearable technology. Demonstrating the latest in WHOLEGARMENT® knitting technology at Techtextil will be the flagship MACH2XS machine that features the company’s original SlideNeedle™ on 4 needle beds and patented springloaded full-time sinker system. Capable of WHOLEGARMENT® knitting in all-needles, MACH2XS offers great flexibility for knitting high-quality WHOLEGARMENT® products with a seemingly endless variety of knit patterns at very high speed and efficiency, all while minimizing dependence upon labor-intensive sewing and linking. At Techtextil North America MACH2XS will be shown knitting a seam-free balaclava in one entire piece using fire-resistant yarn.

Also shown will be the SWG091N2 compact WHOLEGARMENT® knitting machine, also featuring SlideNeedle™ technology. Capable of producing small knitted items from safety gloves and compression socks to more sophisticated industrial applications such as tubular shields and harnesses, SWG091N2 offers unique solutions for the automotive, aerospace, sports, medical, safety, outdoor and other markets by knitting items in 3D without seams. SWG091N2 will be knitting fire-resistant gloves at Techtextil North America. SHIMA SEIKI’s SDS®-ONE APEX4 3D design system will also be available for demonstrations in design and simulation of various technical textiles. Of particular interest is its ultra-realistic simulation capability that realizes virtual sampling. When numerous variations must be evaluated before arriving at a final design, virtual product samples can be used to streamline the decision-making process by minimizing the enormous amount of time and cost normally associated with producing actual physical samples for each variation. The sustainability factor is also undeniable considering the amount of material normally gone to waste in the sampling stage.

The Techtextil and Heimtextil Summer Special exhibitions, taking place together in Frankfurt from June 21-24, represent an opportunity for Monforts to showcase its finishing and coating technologies for two of its major markets – especially at a time when energy prices continue to soar for textile manufacturers in Europe.

Existing customers of Monforts include many manufacturers in the field of home textiles, as well as those making geotextiles, automotive fabrics and other functional materials – all of whom will be well represented in Frankfurt this June. Dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics, as well as high-temperature filter materials.

Energy prices are rising steeply everywhere and a particular emphasis for Monforts in Frankfurt will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as better insulation of the treatment chambers or the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air resulting in a radical reduction in the conventional heat supply required compared to gas and thermal oil heating. The modular system for heat recovery can also be extended for exhaust air cleaning and odour elimination. Monforts can provide a range of further resource-saving and energy recovery options tailored to each individual line installation including modification of the heating source.

With the Qualitex 800 visualization software, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

All of these very different materials require coating and finishing for maximum efficiency, using Monforts technologies which provide the ultimate in flexibility and the ability to switch quickly from one fabric run to the next, without compromising on the economical use of energy or raw materials.

The Monforts EcoApplicator offers further potential for sustainably achieving perfect finishes via a precise direct application system, as an alternative to conventional padding – where fabrics are immersed in a bath of the required finishing chemicals. It can significantly further reduce the energy and water required and finishes can be applied on just one side of the fabric, or both, and even separately on each side, to be sealed in place via different heating zones in the stenter.
