• The unique concept of presenting all renewable material solutions at one event hits the mark: bio-based, CO2-based and recycled are the only alternatives to fossil-based chemicals and materials

Ready-to-use fossil-free sustainable material solutions with a low carbon footprint are in fast-growing demand. Innovative brand owners are keeping an eye out for such solutions, in particular those that will soon reach the mainstream.

For the second time, nova-Institute presents numerous market highlights from bio- and CO2-based chemicals and materials as well as from chemical recycling: All material solutions based on renewable carbon. Together, there is sufficient potential to completely replace petrochemicals by 2050. To tackle climate change at its roots, all additional fossil carbon from the ground must be substituted with renewable alternatives. Over the course of three days, participants will get a comprehensive overview of the latest developments in the renewable material sector, with a focus on industry-ready solutions from a wide spectrum of sustainable raw materials and technologies.

In 2021, the new concept of the Renewable Materials Conference generated an outstanding response, which exceeded all expectations: 420 online participants witnessed a firework of innovations of non-fossil material. 60 speakers, 11 panel discussions, 500 public posts and 1,500 networking activities were proof of the lively exchange during the three conference days.

In 2022, nova-Institute plans to host the conference physically in the heart of Germany's fourth largest city, Cologne, just a few hours away from France, Belgium and the Netherlands. Expected are 400 participants on-site and many more online. On-site, the conference will be accompanied by a large exhibition where companies and institutes can showcase their recent developments. The supporting program, networking activities and many secluded spots at the location offers excellent opportunities to make new business contacts and refresh old ones.

The focus of the conference: All material solutions based on renewable carbon – avoiding the use of additional fossil carbon. The entire spectrum of renewable materials is covered: bio-based, CO2- based and recycled.

The program includes a diverse range of bio-based materials such as bio-based polymers, plastics and biocomposites (first and second generation, biowaste), CO2-based materials (from fossil and biogenic point sources, atmosphere) as well as mechanically and chemically recycled materials.

Suominen has launched a second nonwoven product, HYDRASPUN® Regal, that has received the Fine to Flush Manufacturer’s Generic Certificate from Water UK. HYDRASPUN® Regal was developed to meet the increasing need for flushable wipes that are dispersible according to the Water UK’s flushability standard.

HYDRASPUN® Regal is made of plastic free and biodegradable raw materials, containing only cellulosic fibers. It also has a low-level carbon footprint due to its high pulp content.

Suominen was one of the first nonwoven substrate manufacturers to receive the Fine to Flush Manufacturer’s Generic Certificate from Water UK. The first certification was granted for HYDRASPUN® Royal in Spring 2020.

Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic. It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change. Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That are the motives for Trützschler to develop the intelligent card TC 19i, which sets a new benchmark for energy-efficient carding.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.

In a head-to-head comparison between the TC 19i and a high-performance card from a competitor, the TC 19i consumed at least 10 % less energy per kilogram of material produced when manufacturing rotor yarn from a cotton and cotton waste mix. The compared energy values included electric power consumption and energy required for suction and compressed air and were measured in both cards at the same production of 180 kg/h. A 10 % reduction in energy per kilogram of sliver produced, as proven here by TC 19i, can have a significant impact on a spinning mill’s profitability; annual savings worth a five-digit sum are frequently possible, depending on factors such as the output of the mill. The customer trial also showed TC 19i’s excellent reliability at the customer’s usual production rate of 180 kg/h, and even demonstrated stable performance at 300 kg/h in the same application. Because the TC 19i with T-GO gap optimizer realizes maximum production rates at no compromise in quality, manufacturers can reduce their energy demand and investment costs drastically: Less machines are needed to achieve the desired output, and energy consumption per production is reduced.

This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model.

For the Fall-Winter 2022/2023 BERTO divided their PREMIUM DENIM FABRICS collection into 5 themes.

The first one is ICONIC, where clients can find the “mainstream” proposal, the authentic denim NO SEASON, timeless fabrics with high versatility. From the 100% cotton with salt and pepper look, to the comfort denim really slubby, to the light shirting fabric. Into this theme there are also the Berto NOS, always available for all clients’ needs.

The second theme is BLACK BLOOD. Into this theme clients find Double Black fabrics that have two souls: one made by overdyed sulfur denims, for a washed and aggressive look, and the other given by a reactive black weft, inspired by elegance and sophistication. In addition, we propose to clients also some overdyed reactive fabrics for an intense black look.

The third theme is EVERYDAY PLUSH. With “everyday plush” we want to imagine the desire to dress as if surrounded by a warm hug. In fact, this capsule includes Cashmere denim that ensure warm and soft feeling to the wearer; and “soapy-denim”, a fabric made with cotton and viscose that gives a soft and fluid hand. Moreover, cotton mixed with nylon gives the fabric a technical hand and an elegant image while maintaining stretch performance, lightness and softness.

The fourth theme is JAPAN CALLING. The rough touch-feel and the authentic aesthetic as the true Japanese denim are the main features of the fabrics belonging to this theme. The clients here can find high weight 100% cotton denim fabrics with authentic image and structured weave. To complete the capsule a special blend is available: fabrics with a Tencel slubby weft that gives soft and fluid touch together with a rough image.

Last but not least, the fifth theme: MOTHER NATURE. The container of all the most sustainable Berto fabrics, from Organic cotton fabrics GOTS certified, to Recycled cotton fabrics GRS certified, made regenerating their own production waste.

Linked with this last theme the company will present during BLUEZONE by MUNICH FABRIC START a special capsule collection of garments made with our PIANETA FABRIC, GRS certified and made with recycled cotton coming from their own waste of production. The same waste has been used by CADICA GROUP, an Italian premium trims maker, to do the SPECIAL LABELS and HANGTAGS of this capsule.

• 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.

Indian Tufropes is partnering with Truetzschler Nonwovens and Voith to install its unique pentamerous technology. The company’s first nonwovens production line will be capable to produce 5 different eco-friendly, hydroentangled products.

Truetzschler Nonwovens and Voith are thrilled to be the technology partner for Tufropes’ (patent pending) unique nonwoven line based on pentamerous technology. The new installation relies heavily on Truetzschler/Voith core components for wet-laying, carding and hydroentangling. Proprietary refinements will allow Tufropes to produce any possible hydroentangled nonwoven material, including bio-degradable, natural fibre, eco-friendly high-performance nonwovens. Globally this would be a first industrial-scale pentamerous technology-based nonwoven project. Based in Gujarat, India, the line is expected to be commissioned next year.

Not only since 2021 has sustainability been a topic high on society’s agenda. And yet the importance of sustainability for consumers and companies has once again increased sharply as a result of the Corona pandemic, as numerous studies confirm. Then why is it often so difficult to implement this conviction in everyday life? One of the biggest obstacles to sustainable consumer behaviour is the lack of availability of alternatives.

In addition to changing consumer demands, the EU Commission's recent decision on the single-use plastics directive is also prompting many nonwovens manufacturers to look at alternative solutions. Kelheim Fibres is exhibiting at this year's INDEX in Geneva and online with bio-based fibers that offer an alternative to synthetic materials in a wide range of applications. The Bavarians have decades of experience in the nonwovens and hygiene sectors and work on individual customer-specific innovations.

"We want to make it easy for consumers to choose an environmentally friendly option. That’s the case when bio-based solutions offer the same performance as synthetic products," said Matthew North, Commercial Director at Kelheim Fibres." Our fibre technology allows us to create just that: unlike natural fibres, which are available already in fibre form and can only be treated on the surface, we can engineer the properties of our fibres they need for specific applications by specifically intervening in the production process. That way we combine nature - our fibres are made of wood pulp - with performance."

Kelheim's special fibres are made of wood pulp from sustainably managed sources, are produced in Kelheim in an environmentally friendly way and are fully biodegradable at the end of their product life. Kelheim Fibres is the first viscose fibre manufacturer in the world with an EMAS validated Environmental Management System and was awarded a dark green/light green shirt in the most recent Canopy HotButton-Ranking.

Korteks, one of the world’s biggest yarn producers based in Bursa, Turkey, has started the production of recycled polyester filament yarn in its production facility using a Starlinger recycling line.

With the new recycling facility, which comprises a total closed area of 17,000 m² and has a monthly production capacity of 600 tons, Korteks was able to reduce the production waste at its virgin PES yarn site to zero.

The Starlinger recoSTAR universal 165 H-VAC iV+, which is part of Korteks’ 10 million dollars investment in a new polymer recycling facility, took up operation in May 2021. It has a production capacity of 7,200 tons per year and currently processes clean in-house polyester fibers from production scrap together with washed post-consumer PET flakes at a ratio of 50/50. Korteks uses the polyester regranulate at a share of 100 % for its new polyester filament yarn line it is going to market under the name “TAÇ Reborn”. With this investment, the company has made an important step towards establishing a circular economy in the Turkish textile industry.

The Starlinger recycling line is the first of its kind in Turkey and is equipped with special components for filament yarn recycling. A RSC (Rapid Sleeve Changer) candle filter developed by Starlinger ensures finest melt filtration down to 15 μm. It has been specially designed for polyester recycling and reaches an output of 1000 kg/h. For continuous operation the filter elements are changed “on the fly” without interrupting production, which significantly limits melt loss.

The viscoSTAR SSP unit at the end of the recycling process guarantees consistent IV increase according to the first-in-first-out principle. This makes sure that the produced regranulate has the ideal properties required for filament yarn production. The technical configuration of the line does not only allow the processing of a polyester fiber/PET flake mix as input materials, but also 100 % polyester filament scrap or 100 % PET bottle flakes.

Korteks expects the recycling market in general to grow as there is increased acceptance for recycled products in the society, and predicts the need for recycling solutions also for other synthetic and natural fibers.
