From the Sector

The annual highlight of the industry is the International Conference on Cellulose Fibres in Cologne, where the latest innovations were showcased: new cellulose fibre technologies for various feedstocks and a wide range of hygiene and textile products as well as alternatives to plastics and carbon fibre for lightweight constructions.

This year, for the first time, there were 230 participants from 27 countries. About 60 were able to attend on site – with strict Corona safety measures – while the others were able to attend online and participate in questions and discussions.

The conference gave deep insights into the promising future of cellulose fibres, which fit perfectly into the current trends of circular economy, recycling and sustainable carbon cycles.

An important focus at the conference was alternative sources of cellulose. The increasing demand for cellulose fibres cannot be met in the long run with wood and used textiles alone. At the conference, a variety of agricultural by-products and biogenic waste were presented in presentations and panel discussions, such as orange and banana peels, grain and hemp straw. Much of this is high-volume and has not been put to high-value use so far. Exciting opportunities for the future cellulose fibre industry.

• Sustainability at Milano Unica:  Ecodesign for an environmentally friendly fashion industry.

A ski suit made of yarn obtained from recycled materials and fully recyclable at end-of-life, without giving up on style, design and technical performance: this is RadiciGroup’s business card at the 34th Milano Unica, the international high-end textiles trade show taking place at the Milan Rho Fairground on 1-2 February.

In the Innovation Area of TexCubTec, Sistema Moda Italia’s technical and functional textile section, visitors can see and touch the new uniform of the RadiciGroup Ski Club designed by RadiciGroup in collaboration with the DKB sportswear brand.

“The ski suit, consisting of jacket and trousers, is fashioned with fabric made of RENYCLE®, a RadiciGroup yarn obtained from mechanically recycled nylon,” pointed out Marco De Silvestri, sales & marketing manager – Apparel and Technical of RadiciGroup Advanced Textile Solutions business area. “In addition, the suit’s padding and numerous accessories, such as zippers, Velcro, buttons and thread, are also made of polyamide. It was an ambitious project and we reached a definitive goal: circularity in sportswear without compromising on performance. A goal achieved through continuous close collaboration with other companies in the chain to develop chemically compatible materials that guarantee the high technical performance required by this kind of application.”

At Milano Unica, besides RENYCLE®, RadiciGroup is showcasing garments made of   REPETABLE®, a polyester yarn obtained from post-consumer recycled plastic bottles, and articles made of BIOFEEL®, a brand identifying both nylon and polyester yarn made from renewable source materials.

As part of their EMAS certification, the company has already been publishing an annual environmental statement since 2020, in which all relevant environmental data are available to the public. The Sustainability Report, which will also be published annually, goes one step further here - it covers not only the company's environmental performance, but also Corporate Social Responsibility as a whole.

Following this approach, the fibre experts have also created a new structure internally, which gives even more weight to the area of CSR: In future, all sustainability topics will be centrally integrated in the new CSR department (formerly HSE, Health, Safety & Environment) under the leadership of Wolfgang Ott.

The AVK – Industrievereinigung Verstärkte Kunststoffe – has once again presented its Innovation Awards to companies, institutes and their partners. Three composites innovations were recognised in each of the three categories – “Innovative Products/Applications”, “Innovative Processes” and “Research and Science” – at the new event JEC Forum DACH on 23 November 2021, the first edition of which was held in Frankfurt.

“As usual, the submissions included a lot of very interesting and promising products and processes this year. The Innovation Awards highlight the outstanding efficiency, cost-effectiveness and sustainability of fibre-reinforced plastics as well as the companies and institutes operating in the sector,” explains Dr. Elmar Witten, Managing Director of the AVK. The jury of leading experts from the industry honoured the following innovations this year:

Category “Research and Science”
First place in the “Research and Science” category was awarded to the German Aerospace Center (DLR) for its Bondline Control Technology (BCT). This innovative process is used for quality control and assurance of bonded joints. The core element is a porous fabric which is applied to a joining surface using an epoxy adhesive or matrix resin. Peeling away the fabric creates a chemically reactive and undercut surface and can also be used as a test to check adhesion to the substrate. BCT has potential in a variety of possible applications. For example, peel ply can be replaced by BCT fabric to produce composite components with an optimised joining surface. The cost-effective BCT peel test is suitable for coupon testing and process control. In addition, the combined adhesion test and surface pre-treatment can be used for quality assurance of bonded repairs on fibre composite structures.

Second place was taken by the Institute of Textile Technology (ITA) at RWTH Aachen University and its partners AEROVIDE GmbH, Altropol Kunststoff GmbH, Basamentwerke Böcke GmbH, TechnoCarbon Technologies GbR with “StoneBlade – Lightweight construction with granite for the wind industry”. This innovation enables manufacturers to reduce the amount of non-recyclable materials used in rotor blade construction. At the same time, it reduces the weight of these components and improves the mechanical properties relating to the stability of wind turbines. The innovative approach replaces glass-fibre reinforced plastic in the blade components with hard rock – a natural, cost-effective and recyclable lightweight material. The slabs of rock are cut and ground to a thickness of just a few millimetres and embedded in a fibre composite laminate with carbon fibre, which stabilises them for alternating load cases. The pre-stressed material is pressure-stable in the composite and can absorb tensile forces in the event of continuously alternating loads without any loss of stiffness.

Third place went to the Dresden University of Technology – Institute for Lightweight Construction and Plastics Technology (ILK) with its partner Mercedes Benz AG for the interdisciplinary development of a highly integrated inductive charging module for electric vehicles. The ultra-thin charging module was designed to make optimum use of space in the vehicle underbody without reducing ground clearance. An interdisciplinary approach was adopted for the development process. This involved the electrical, mechanical and process characterisation of high-frequency Litz wires, ferromagnetic foil and metal wire cloth as well as the creation of a simulation model. The result is a demonstrator for a charging system with a structural height of 15 mm and a total weight of 8 kg. It achieves a transmission efficiency of up to 92 percent at 7.2 kW nominal power and active air cooling. The hardware demonstrator was fabricated in a 3-step process using RTM and VARI techniques.

Members of TMAS – the Swedish textile machinery association – are proving instrumental in pioneering new sustainable processes for the dyeing, finishing and decoration of textiles.

The wasteful processes involved in these manufacturing stages are only one component in the development of viable circular supply chains for textiles that are now being established in Sweden.

At the recent Conference on Sustainable Finishing of Textiles, held across three separate afternoons on September 30^th, October 1^st and October 7^th, delegates heard that Sweden will introduce extended producer responsibility (EPR) for waste textiles and clothing at the beginning of 2022, ahead of the adoption of a similar European Union-wide EPR system in 2025.

New fibers
Swedish companies are also active in the development of new fibers derived from waste clothing, building on the country’s legacy leadership in pulp and paper production.

At the Sustainable Finishing of Textiles Conference, however, it was said that all of the environmental gains made by such sustainable new fibers can potentially be cancelled out in the further processing they are subjected to – and especially in resource-intensive conventional dyeing, finishing and decoration.

TMAS members Baldwin Technology and Coloreel have both developed solutions to address this issue.

TexCoat G4
During the conference, Baldwin’s VP of Global Business Development Rick Stanford explained that his company’s TexCoat G4 non-contact spray technology significantly reduces water, chemistry and energy consumption in the finishing process. It consistently and uniformly sprays chemistry across a fabric surface and applies it only where needed, on one or both sides.

Instant coloring
Coloreel’s CEO Mattias Nordin outlined the benefits of his company’s technology which enables the high-quality and instant coloring of a textile thread on-demand and can be paired with any existing embroidery machine without modification. This enables unique effects like shades and gradient to be achieved in an embroidery for the first time.

10 years after the installation of the photovoltaic plant in the production units in the Biellese region, the Marchi & Fildi Group takes stock of the operation and publishes the data on energy produced, consumed, and fed back into the grid.

The photovoltaic plant owned by the Group is made up of 11,385 modules divided between the three facilities in Biella (Production), Cerrione (Dyeing mill) and Verrone (Logistics), which in total cover a surface of 16,515 sq.m.

The balance to be drawn from these 10 years is a positive one: in total 22,974,828 kWh have been produced, of which 7,292,027 kWh have been used in company activities, with a saving in energy costs of approximately €1m over 10 years.  

The energy kWh produced and not used by the company was fed back into the grid and corresponds to the average annual consumption of around 4630 families.*

The Marchi & Fildi Group has always been committed to rationalising electric energy consumption with the aim of contributing towards an eco-sustainable development without compromising the rate of production and the ability to grow. In addition to producing its own electric energy, over the years, the company has also achieved an increasing number of Energy Efficiency Titles (TEE), otherwise known as white certificates. In 2021, 138 TEEs have been awarded as a result of such interventions as the introduction of LED lighting and the optimisation of the production processes which, while still as efficient as before, permit the company to reduce the electric energy consumption of the machinery.

*In the meter class for the range of 3kW to 4.5 kW, the average consumption for residential properties is the equivalent of 3,382 kWh (source: Arera Relazione annual state of services for the year 2020). The calculations are the results of an internal study conducted by the Marchi & Fildi Group.

Beaulieu Fibres International is attending INDEX™20 in Geneva and is excited to accelerate its work helping customers to exceed in product performance and sustainability.

For nonwoven converters serving the hygiene segment, a feature at INDEX™20 will be the company’s optimized Meralux specialty fibre, with fit for use performance and sustainability properties. It offers opacity improvements (reduction of TiO2 for the same opacity levels), higher coverage, higher bulkiness, and improved liquid management.

In addition, Meralux fibres deliver substantial sustainability benefits including about 55% savings in raw materials, with equivalent carbon emission savings, thanks to weight reduction in nonwovens for the same coverage, and higher recyclability of PP/PE.

The latest additions to the hygiene fibres portfolio are Meraspring BICO PET fibres. Meraspring enables nonwovens to combine a softness and loftiness that provides a cushioned, even “well-being”, experience for end-users of applications such as diapers and fem-pads. The fibres are available in a range from 1.7-8.9 dtex with hydrophilic, hydrophobic and wellbeing finishes depending on the properties required in the final product.

In the industrial fibres segment, UltraBond thermal bonding fibre will finally be presented with its INDEX™20 Nonwovens Award in the category "sustainable raw material".

In addition, Beaulieu Fibres International’s new range of MONO low count and BICO fibres are setting new performance standards for the fast-growing air and liquid filtration markets.

At INDEX™20, Beaulieu Fibres International also presenets its Pilot Line to test the waters of co-development opportunities without risk. The Pilot Line offers the utmost flexibility to produce samples, without the typical constraints imposed by industrial production lines, replicating any type of staple fibre spinning technology using different types of polymers and additives and different types of cross sections.
