From the Sector

International technology group ANDRITZ has received an order from Predo Health Products Inc, Türkiye, for delivery of two high-speed hygiene converting lines to produce adult open diapers and feminine sanitary napkins. With this investment, Predo is entering the growing adult and femcare market. The company already operates four baby diaper lines from ANDRITZ.

The two state-of-the-art lines are designed for high-speed production and contain the most advanced forming technology for absorbent core and SAP (superabsorbent polymers) dosing. Based on their flexibility and user-friendly configuration, Predo will be able to produce a wide range of different product compositions and sizes. In addition, the lines are designed for zero waste production. This will enable Predo to produce high-performing products with a sustainable approach.

The lines will be installed in Predo’s factory in Gaziantep, with start-up scheduled for the first half of 2024.

Predo is one of the leading manufacturers of baby care products and is expanding its business to other hygiene sectors. The company exports to 55 countries across the globe.

From April 25^th to 27^th, 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.

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.

SABIC will present its portfolio of PURECARES™ and TRUCIRCLE™ materials for the healthcare and hygiene market at INDEX™23 from April 18 to 21 in Geneva, Switzerland, under the theme of ‘Collaborating for sustainability and innovative solutions’.

At INDEX, SABIC will highlight a joint project with two market leaders, using certified circular polymers from the TRUCIRCLE portfolio in recyclable films for feminine hygiene, baby care and disposable medical applications. In all of these cases from diapers to surgical drapes and medical gowns, the sustainable materials can serve as direct drop-in alternatives with no compromise in production efficiency and product performance.

Further examples on display at the company’s booth will feature TRUCIRCLE solutions for facemasks, including an N95 design that localizes the value chain with SABIC® PURECARES PP spunbond and meltblown polymers in Saudi Arabia. SABIC provides complete solutions for facemask production as part of its localization strategy and has been a key enabler of the Saudi Made initiative. Also shown will be a closed-loop facemask developed in collaboration with industrial and research partners in Europe.

The company’s PURECARES polyolefin products are based on technologies free of both tris (nonylphenyl) phosphite (TNPP) and phthalates. Consumer comfort is achieved by using SABIC polypropylene (PP) and polyethylene (PE) polymers for bi-component fibers to answer multiple needs for soft and loft handfeel nonwovens, enabling easy lamination to other building blocks on medical nonwovens or absorbent hygiene applications.

In addition, SABIC produces TRUCIRCLE certified circular polymers for its PURECARES PP and PE portfolio with feedstock based on advanced recycling of mixed and used plastic that would otherwise typically not be suitable for mechanical recycling processes. These more sustainable solutions can be adopted in downstream processes as direct drop-in alternatives to incumbent materials with no compromise in production efficiency, purity and product performance.

• Electromagnetically heatable nanomodified stent for the treatment of hollow organ tumours wins second place at the RWTH Innovation Award

Almost every fourth person who dies of cancer has a hollow organ tumour, for example in the bile duct or in the oesophagus. Such a tumour cannot usually be removed surgically. It is only possible to open the hollow organ for a short time using a stent, i.e. a tubeshaped prosthesis. However, the tumour grows back and penetrates the hollow organ through the stent. Ioana Slabu from the Institute of Applied Medical Technology and Benedict Bauer from the Institut für Textiltechnik of RWTH Aachen University have now developed a novel technology for the therapy of hollow organ tumours, which was awarded second place in the RWTH Innovation Award. This involves a polymerstent that contains magnetic nanoparticles. When electromagnetic fields are applied, these nanoparticles lead to a controlled heating of the stent material and thus of the tumour. Because the tumour reacts much more sensitively to heat than healthy tissue, it is destroyed and the hollow organ remains open. Thus, the stent develops a self-cleaning effect.  

Ioana Slabu of the AME explains: "Not only can we drastically reduce treatment costs, but above all we can provide relief for millions of patients worldwide.
 
A manufacturing process and proof of concept for magnetic hyperthermia are already in place. This novel technology has a very high development potential because it can also be used for tumours in other parts of the body such as the prostate, stomach, intestine or urinary bladder or for cardiovascular diseases.  

The AiF/IGF project started under the project title "ProNano" funded by BMWK. Now the approval for the follow-up project "ProNano2" has also been received. The approved project is called: "Validation of the innovation potential of heatable stents for heat-induced treatment of cavity tumours" and is funded by BMBF in course of the VIP+ program. With the Clinic for General, Visceral and Transplantation Surgery of the University Hospital Aachen and the Institute for Technology and Innovation Management at RWTH Aachen University, the consortium is enriched by clinical and economic expertise. Every year, RWTH Aachen University honours particularly innovative university projects with the Innovation Award. Professor Malte Brettel, Prorector for Business and Industry, presented the certificates to four outstanding projects as part of RWTHtransparent.

A little over three years have passed since RadiciGroup announced the acquisition of Zeta Polimeri, an Italian company headquartered in Buronzo (VC) with over 30 years' experience in the recovery of pre- and post-consumer synthetic fibres and thermoplastic materials. Today, the company has become a full member of the Group with its new name Radici EcoMaterials Srl.

The new company’s long-standing know-how, combined with RadiciGroup’s as a whole, will create a virtuous production system that recovers worn-out materials (fabric, yarn and granules), or otherwise unusable materials, and processes them into raw materials available for other production cycles by taking advantage of industrial synergy.

Radici EcoMaterials is a strategic production site because it handles all the preliminary recovery stages: the sorting, processing and pre-treatment of materials, including those used for the production of post-consumer yarns and engineering polymers. In this sense, Radici EcoMaterials is in line with the most recent European policies on sustainable textiles, which address minimizing the share of materials destined for disposal sites, favouring instead more structured recycling solutions.

Radici EcoMaterials is also GRS certified. GRS certification ensures the complete traceability of its materials, which are made in a safe plant that meets the highest environmental and social certification standards.

The company is also equipped with a photovoltaic system and, for the portion of its energy needs not covered by the photovoltaic source, it partially relies on renewable energy. The goal is to use 100% green energy in the next few years, in accord with RadiciGroup's goals.

RadiciGroup presented Biofeel® Eleven, a yarn of natural origin, at the Performance Days trade fair (from March 15-16 in Munich). Biofeel® Eleven is sourced from castor oil and is suitable for obtaining bio-polymer. It can be used for fabrics and fine garments in many sectors, from fashion to sports, from automotive to home textiles.

Today, 80% of the world's castor-oil plantations are in India, particularly in the Gujarat region, due to its favourable climatic conditions. In this area, local people can earn an additional income by cultivating semi-arid land that does not compete with food production, and by applying the skills they have acquired over time to this work. Over the years, thanks to research, development and innovation in the value chain, the seeds from which the oil is produced have been selected and certified to ensure the finest quality, also in terms of end uses.

Castor beans contain around 45% oil, rich in ricinolein, from which the bio-polymer polyamide 11 is derived. This is the polymer RadiciGroup uses for its Biofeel® Eleven yarn. What remains after the first pressing is a highly effective bio-fertiliser that is returned to the soil.

Biofeel® Eleven can also be solution dyed, i.e. dyed at the yarn production stage, saving a great deal of water and energy and also providing greater colour stability.

Freudenberg Performance Materials (Freudenberg) will present surfacing veils and core materials for lightweight fiber reinforced plastic (FRP) parts at JEC in Paris, France. Freudenberg will also be showcasing Enka® Solutions flow media and spacers for efficient vacuum infusion, resin transfer and foam injection molding processes for applications in the composites industry, etc. at the international composites show.
 
Freudenberg’s solutions for the FRP industry include a variety of glass, PAN and PET nonwovens, as well as core materials for the production of lightweight fiber reinforced plastic parts. These products are designed for anti-corrosion coatings in piping and tank construction, smooth UV resistant surfaces for facade panels, and other applications for a diverse range of end products. Products made from fiber reinforced plastics must be equipped with surfacing veils to provide abrasion resistance, corrosion resistance, smooth surfaces and mechanical strength. Freudenberg offers high-tech nonwovens that can meet these challenges.
 
Enka® Solutions products are characterized by their typical 3D entangled polymeric filament structures. Thanks to this structure, they are exceptionally suitable as flow media and spacers when producing composite materials.

Fibre Extrusion Technology Limited (FET) of Leeds, England, a supplier of laboratory and pilot melt spinning systems, is celebrating a record breaking year of sales and product innovation. “Sales revenue for 2022 has easily beaten our previous high” said FET Managing Director, Richard Slack “and the research projects we have collaborated in have become increasingly challenging in terms of technical specification.”

Prestigious new projects during 2022 included a multifilament melt spinning line for Senbis Polymer Innovations, Netherlands enabling the development of textile fibres from recycled polymers or biopolymers; a FET-200LAB wet spinning system at the University of Manchester which will play a major part in advanced materials research in collaboration with the renowned Henry Royce Institute; and a FET-103 Monofilament line for RHEON LABS of London to help develop a hyper viscoelastic fibre from RHEON™ which displays high strain-rate sensitive properties. The latter two of these examples were aided by significant UK grants to develop advanced materials.

FET is now looking forward to 2023 with a record order book. The company’s newly opened Fibre Development Centre features over £1.5 million investment in customer laboratory systems that will further enable fibre trials and product R&D. Three new polymer types were developed with clients in 2022 and several more are lined up in 2023, which is expected to bring the total of different polymer types to more than 40 in multifilament, monofilament and nonwoven formats.

FET will be exhibiting at two major exhibitions in 2023; INDEX 23, a leading Nonwovens show at Geneva in April; and ITMA, Milan, an international textile and garment technology exhibition in June.

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.
