From the Sector

The Gleaming line by the Marchi & Fildi Group includes a wide range of metalloplastic yarns for the most varied of uses. Reflex, the new range of reflective yarns, will join the line.

In addition to uses in the worlds of fashion and furnishings, for fancy yarns, decoration and accessories, an important application for the Gleaming collection is in the sector of technical clothing with high-visibility features.

Reflex, used for the production of fabrics and tapes, able to reflect the light and ensure good visibility for people wearing them in low-light situations, is augmented by new colour shades in addition to the traditional greys.

The innovative reflective yarns in white, black, and light and dark multicolours offer new possibilities for:

• tapes, external labels and accessories;
• technical fabrics for work clothing with specific safety standards;
• uniforms, sports clothing and accessories;
• hosiery, gloves, bibs and hats for night use, for winter clothing and for northern markets.

The latest addition to the range, with an important functionality, is the Reflex stretch yarn, which, apart from in the sectors described above, also finds application in flat bed or circular knitting and sewing. Its composition makes it softer and more versatile in comparison to traditional reflectives.

The Gleaming line represents a completion of the range of yarns produced by the Marchi & Fildi Group. The yarns are available in various thicknesses, widths and types in both metallised and transparent versions, and iridescent, reflective and phosphorescent effects. Also articles are included with particular features of resistance to chemical and dyeing treatments.

Amongst the most recent innovations is the line of metalloplastic yarns in 100% polyester obtained from post-consumer recycling with GRS (Global Recycle Standard) certification.

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.

Ganesha Ecopet Private Limited, a subsidiary of Indian PET recycling pioneer Ganesha Ecosphere Ltd., has recently opened its new Warangal facility under the brand name Go Rewise where it produces rPET for filament yarns and fibres, as well as for food-grade packaging.  

The company has installed two Starlinger PET recycling lines in its facility in Warangal, Telangana state. Ganesha Ecopet plans to supply the produced rPET granulates under its newly introduced brand enterprise Go Rewise. Launched under the umbrella of one of India's rPET industry leaders, Go Rewise is committed to supplying highest quality rPET products that are produced in a resource-efficient process.
One Starlinger recycling line, a recoSTAR PET 165 H-VAC, processes washed PET bottle flakes for the Go Rewise polyester filament yarn applications and reaches an output of approx. 14,000 tons per year. With the second Starlinger recycling line, Ganesha is producing food-grade rPET resins.

Ganesha Ecosphere looks back on 30 years of experience in the PET recycling business and can be considered a role model regarding sustainable business activities. Founded in 1987, the company started out as a yarn processing facility. It was among the first companies in India to start reprocessing PET waste to manufacture recycled polyester staple fibre (RPSF) and recycled polyester spun yarns (RPSY) in 1994. By today, the group has established a large network of over 300 scrap vendors located across the country and operates four factories in India - two in Uttar Pradesh, one in Uttarakhand, and the recently opened one in Telangana. It also recently operationalised its first factory outside India in Nepal. With over 500 customers and exports to more than 18 countries, the company ranks among the largest rpet producers in India with 130,000 tonnes per year and currently recycles around 16 - 18 % of India's total PET waste.

Indorama Ventures Public Company Limited (IVL), a global sustainable chemical company, announced its commitment to science-based targets by the Science Based Targets initiative (SBTi) to help drive its ambitious sustainability programs. The company will also participate in the SBTi Expert Advisory Group for the chemicals industry.

SBTi is a collaboration between CDP, the United Nations Global Compact, the World Resources Institute, and the World Wide Fund for Nature to help businesses set emissions reduction targets based on the most recent climate science. IVL has committed to science-based targets under its purpose of “Reimagining chemistry together to create a better world” which aims to reduce global warming in line with the 1.5°C Paris Climate Agreement.

Under its Vision 2030 ambition, Indorama Ventures aims to build on its global industry leadership in sustainability, including by reducing GHG intensity by 30% and increasing renewable electricity consumption to 25%. Green projects are helping the company to achieve its operational efficiency targets, increase its use of renewable energy (especially renewable electricity – both onsite generation and offsite procurement through power purchase agreements), implement new decarbonization technologies including carbon capture, introduce bio-feedstock to its petrochemical value chain, and expand its PET recycling capability.

To meet its targets, IVL recognizes the importance of collaboration between the public and private sectors to decarbonize its operations through a variety of strategies. The established targets help its customers and suppliers to achieve their own sustainability goals, particularly their science-based targets.

IFFAC (Impact Fund for African Creatives) has revealed plans which will revolutionise West African textile and garment production at one stroke. The fund is converting a partially disused textile mill in the region into a hi-tech centre for processing local cotton and recycling waste fabric, to produce both fabric for further processing and new clothes. The mill will be equipped with modern equipment, all sustainably powered by hydroelectricity from the nearby Volta Dam.

West Africa grows about 6% of the world’s cotton but only a tiny fraction of that crop is processed on the continent, the vast majority being shipped thousands of miles to Asia before being shipped back again as finished or part-finished fabrics. The mill project will end the continent’s reliance on such an unsustainable practice with all the obvious financial and environmental benefits.

As well as producing fabric from sustainably grown virgin cotton, a joint venture with Shandong-based WOL Textiles Ltd., a privately owned plant that has long supplied the African market, the mill will be home to a state-of-the-art shredding and recycling facility, a joint venture between IFFAC and the Dutch Circularity B.V. CEO Han Hamers of Circularity B.V. in The Netherlands, has been involved in the production of 100% circular knit and woven articles.

The mill project is expected to create over a thousand jobs. The surrounding area already boasts a significant number of experienced textile workers ready to be retrained on the new equipment. While the majority of the products created will be sold within the region, all processes will confirm to new EU Supply Chain Law to allow for the possibility of export.  

Output is forecast at six million pieces of finished clothing and twenty-five million metres of spun and woven cloth per year. In total, thirty million US$ of investment will be made in the site with operations ready to begin next year (2023).

Indorama Ventures Public Company Limited (IVL) named the winners of ‘RECO Young Designer Competition’, Thailand's largest upcycling fashion design event, parading haute couture garments containing at least 60% recycled materials.

The adidas TERREX HS¹ is one of the first knitted products to be made in part with Spinnova technology. At least 30% of the fabric in this mid-layer hiking hoodie comes from wood-based SPINNOVA® fibres (other fibres)* and 70% from cotton (organic).

Adidas is committed to helping End Plastic Waste via a three-loop strategy that consists of using recycled materials, materials that can be made to be remade and in the case of Made with Nature, products created in part with natural ingredients, such as the adidas TERREX HS¹.  

The first product to emerge from this partnership, the adidas TERREX HS¹ mid-layer is a piece of multi-functional gear that works on the trails and then rolls up into its hood for easy storage or to create a pillow on longer adventures. It was designed using UNITEFIT – an all-gender fit system created with a spectrum of sizes, genders, and forms in mind.

Made in part with Spinnova technology , a minimum of 30% of the fabric in the adidas TERREX HS¹ comes from wood-based SPINNOVA® fibres (other fibres)* that are made by grinding wood pulp with water into a paste and then spun into a textile fibre.

The product also works with the material’s natural color. Since no dyeing or bleaching is applied, in turn this uses less water compared to the standard dyeing process.

Seit mehr als sieben Jahren forscht Texaid, das seinen Deutschland-Sitz im hessischen Darmstadt hat, daran, wie textile Altfasern und Abfälle vor dem Verbrennen bewahrt und weiterverwendet werden können. Deswegen arbeitet das Unternehmen unter anderem mit Partnern aus der Industrie, dem Recyclingatelier ITA Augsburg von der RWTH Aachen, vertreten von Prof. Dr. Stefan Schlichter, und der Hochschule Augsburg, vertreten von Prof. Dr. Nadine Warkotsch, unter anderem Vizepräsidentin für Forschung und Nachhaltigkeit, an Verfahren, mit denen auch textile Abfälle länger im Verwertungskreislauf gehalten werden können.

Die Basis für diese Forschungen bildet auch das Werk in Apolda. Dort werden täglich rund 350.000 Kleidungsstücke und andere Textilien sortiert. Bei vielen Textilien ist es nicht möglich, sie als Ganzes im Verwertungskreislauf zu halten. Sie werden deswegen sortenrein sortiert, um ein Recycling ihrer Fasern zu ermöglichen.

Seit einigen Monaten wird dies durch innovative Technik unterstützt. So wurden zu Testzwecken einzelne Arbeitsplätze hochtechnisiert. Neben Nah-Infrarot-Scannern zur Analyse der stofflichen Zusammensetzungen der Textilien ist ein Arbeitsplatz mit einem NFC-Lesegerät ausgestattet. „So können wir bereits heute digitale Produktpässe von Textilien auslesen“, so Texaid-Geschäftsführer Thomas Böschen. Um die Recycling-Quote zu erhöhen, plant die EU, künftig jedes Textil mit Chips auszustatten, die Informationen über Herstellung, Zusammensetzung und Möglichkeit der Weiterverwertung geben.

Texaid hat eine Shoppingtasche als erstes eigenes Produkt mit einem solchen Chip ausgestattet. Die Tasche besteht zu 50 Prozent aus Garnen von recycelten Alttextilien und zu 50 Prozent aus Polyesterfasern, die aus Ozeanplastik hergestellt wurden.

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

The European Pultrusion Technology Association (EPTA) has published a report from its latest conference, which focuses on advances in sustainability and recycling.

More than 130 professionals from the global pultrusion community gathered at the 16th World Pultrusion Conference in Paris on 5-6 May 2022. Organised by EPTA in collaboration with the American Composites Manufacturers Association (ACMA), the event featured 25 international speakers sharing insight on market trends, developments in materials, processing and simulation technologies, and innovative pultruded applications in key markets such as building and infrastructure, transportation and wind energy.

‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.
