EREMA presents a new solution for PET fibre-to-fibre recycling

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

ITM at JEC 2023

From April 25th to 27th, 2023, the Institute of Textile Machinery and High Performance Material Technology (ITM) of TU Dresden will be exhibiting at the pavilion SAXONY! at JEC World 2023.

The ITM will provide a comprehensive overview of its current research in the field of machine and product development along the entire textile process chain.

The upcoming JEC 2023 exhibition will highlight innovative Customised Connective Cores (CCC), which are custom-made core-insert structures additively manufactured using cellular metal and a form-fit integrated insert. These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

Another highlight at the exhibition is the repair process for fibre-reinforced composites (FRP) developed at the ITM. Instead of mechanically grinding the damaged area, the matrix in the repair area is locally dissolved using a UV-rays-induced depolymerisation process. Damaged fibres can thus be replaced by a customized repair patch. Free yarn ends on the textile repair patches are spliced with the UV-exposed yarn ends in the repair area using an adapted splicing process. In this way, a very clean, simplified and mechanically improved repair area can be achieved compared to the state of the art.

The diverse possibilities offered by the structure and process simulation of textile high-performance materials and textile manufacturing processes will also be presented. By means of multi-scale modelling and simulation, a profound understanding of materials and processes is achieved at the ITM. Finite element models on the micro, meso and macro scale have been developed and validated for this purpose. Examples from current ITM research projects demonstrate the various possibilities and areas of application of modern simulation methods in the field of textile technology.

Moreover, an innovative process for the integral manufacturing of 3D rib-stiffened preforms with complexly arranged stiffeners in 0°, 90° and ± 45° orientation was developed and successfully implemented at the ITM. Due to the process-integrated structure fixation and the continuous fibre reinforcement between shell and rib structure, the 3D preforms are perfectly suited for the production of highly load-bearing FRP components with increased bending stiffness, which will be exhibited at JEC. Hence, the lightweight construction potential of high-performance fibres can be fully exploited.

A successfully established development are partially flowable 2D textile reinforcement fabrics that are continuously manufactured in one single process step. For this purpose, the entire process chain was developed at the ITM, which allows a cost-effective and high-volume production of load-bearing thermoplastic 3D FRP components with continuous fibre reinforcement between shell and stiffeners.

At JEC 2023, the ITM will also present a partially embedded textile latice girder as reinforcement for carbon concrete applications, which was produced by means of an innovative textile manufacturing process based on the multiaxial warp knitting technology. Through the development of a customized warp insertion, manipulation and take-off system as well as appropriate shaping methods, it is now possible to produce tailored textile semi-finished products, e.g. for use in wall and ceiling panels. These textile latice girders represent a resource-saving alternative to conventional steel girders due to the reduced among of concrete required and the additional cavity for media and cable guidance.

The integration of textile actuators and sensors in FRP provides structures with additional functionalities. The research and application of such interactive FRP with different matrix materials (e.g. with thermoset, elastomer or concrete matrix systems) for structural health monitoring or adaptive systems is one of the key research areas of the ITM.

Moreover, the development and implementation of innovative yarn constructions based on recycled high-performance fibres (e.g. rCF, rGF, rAR) for sustainable FRPs is successfully promoted at ITM. By use of a special carding machine, recycled fibres are opened up, separated and joined to form a wide, uniform ribbon. Subsequently, innovative hybrid yarn constructions made of evenly mixed recycled high-performance and thermoplastic fibres with variable fibre volume fractions can be manufactured by means of various spinning technologies. Selected yarn constructions and components will be showcased at JEC.

DiloGroup at India ITME 2022

DiloGroup will be attenting India ITME 2022 (December 8 – 13, 2022), an exhibition for the textile industry, which offers a central forum for dialogue within the textile production sector, including textile machine building, fibre production, ancillaries and accessories. For DiloGroup this event is a good oppportunity to inform customers and interested parties about new developments aimed at improving production technologies with a focus on needlefelts.

For DiloGroup this event is a good oppportunity to inform customers and interested parties about new developments aimed at improving production technologies with a focus on needlefelts.

Focal points of the development work are:

  1. Intense Needling:
    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.
  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. It is also suited for 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.

DiloGroup at Techtextil with nonwovens technology

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:

In addition, the CETI (European Center for Innovative Textiles) in Lille, France, has installed an air-through-bonding oven from ANDRITZ.

Textil-recycling Technologies
Recently, ANDRITZ acquired Laroche SAS, a leading supplier of fiber processing technologies such as opening, blending, dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. The product portfolio further complements and increases the ANDRITZ Nonwoven product range. One focus of this product range lies on complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end uses.

Needlepunch Technologies
Driven by the dynamic market for durable nonwovens, ANDRITZ has developed an elliptical pre-cylinder tacker – the PA3000. With this modern machine, ANDRITZ is responding to customer demands for higher capacities and lighter products. The PA3000 is an optimized cylinder pre-needleloom, which offers greater speeds and widths and has been specially developed for lighter webs. There is no friction between the web and the rolls, and there are no issues with the visual appearance.

ANDRITZ is also focusing on its latest needling technology for producing veloured felts, mainly for applications in the automotive industry.

In addition, ANDRITZ will be presenting the next generation of its batt-forming technology, the ProWin system. ProWin is a further development of ProDynTM and ProWidTM, which have achieved a high level of acceptance on the market with around 200 systems installed. This technology improves the current weight-profiling options and increases the actual production capacity.

Production of Bio-Wipes
For many years now, ANDRITZ has offered different nonwoven processes, such as spunlace and Wetlace, with one goal in mind: reduction and elimination of plastic raw materials while maintaining the high quality of the desired product properties. The latest development in this field is the ANDRITZ neXline wetlace CP line. This is a fully engineered production line, combining the benefits of wetlaid and drylaid technologies to produce a new generation of biodegradable wipes. This process achieves 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.

FET installs new Spunbond system at University of Leeds

Fibre Extrusion Technology Ltd, UK has completed the installation and commissioning of a new FET Laboratory Spunbond system for the University of Leeds.

Fibre Extrusion Technology Ltd, UK has completed the installation and commissioning of a new FET Laboratory Spunbond system for the University of Leeds.

This FET spunbond system is now an integral part of the research facilities of the CCTMIH (Clothworkers’ Centre for Textile Materials Innovation for Healthcare), led by Prof. Stephen Russell based in the School of Design, University of Leeds, who commented “The new spunbond system is perfectly suited to our academic research work, and is already proving itself to be extremely versatile and intuitive to use”.
 
This spunbond system complements existing research lab facilities at the university, which covers all areas of fibre and fabric processing, physical testing and characterisation. It forms part of a wider investment in facilities to support fundamental, academic research on ‘future manufacturing’ for medical devices, where the focus is on studying small-scale processing of unconventional polymers and additive mixes to form spunbond fabrics with multifunctional properties.
 
Key to this research is developing the underlying process-structure-performance relationships, based on the measured data, to provide detailed understanding of how final fabric performance can be controlled during processing.

As a rule, many exciting materials developed in academic research struggle to progress beyond the bench, because of compatibility issues with key manufacturing processes such as spunbond. By leveraging mono, core-sheath and island-in-the-sea bicomponent technology, the Leeds University team is working with polymer and biomaterial research scientists, engineers and clinicians to explore the incorporation of unusual materials in spunbond fabrics, potentially widening applications.
 
FET has built on its melt spinning expertise to develop a true laboratory scale spunbond system and is currently working on a number of other such projects globally with research institutions and manufacturers.
