From the Sector

Geosynthetics have become an indispensable part of the construction industry. PP nonwovens, for example - mechanically bonded continuous fibres made from specially UV-stabilised polypropylenes - are often used in blanket form as barriers, screens and filters, and their strength extends the service life of construction projects. Whether for road construction, or as barrier on glaciers or against weeds - there are myriad applications.

TenCate Geosynthetics uses the PURE LOOP ISEC evo technology to recycle this type of PP nonwoven. The European company, with locations in Austria, France and the Netherlands, is specialised in the development and production of geotextiles for modern civil engineering applications. The edge trimmings and production rejects generated during manufacturing used to be recycled at the Linz site, but not fed back into the company's own production process.

"The demands on us were high," recalls Patrick Wiesinger, project manager at PURE LOOP. "The PP nonwoven is highly tear resistant, which means its a very challenging recycling process. Our ISEC evo machine conserves the quality of the production waste really well during recycling, so we were able to achieve the specified increase in quality for the recyclates."

Another advantage of PURE LOOP technology is the wide range of shapes in which the production scrap can be delivered for processing. "Our ifeed technology with double feed ram system and singleshaft shredder offers the ideal conditions for direct processing of these large rolls - and without the need for prior preparation of the input material by employees before the material is fed into the recycling process", emphasizes Patrick Wiesinger. With the ISEC evo recycling machine TenCate can now manufacture its high-strength PP nonwoven product with a recyclate content of up to 10 percent.

Due to the continued good business development, especially in the Carbon Fibers Business Unit, SGL Carbon SE is increasing its Group sales and earnings guidance for the current fiscal year and now expects Group sales of approximately €1.2 billion (previously: approximately €1.1 billion). The company expects to achieve adjusted EBITDA (EBITDA pre = earnings before interest, taxes, depreciation and amortization before one-off effects and non-recurring items) of €170 - €190 million (previously: €130 - €150 million) in 2022.

Based on lower prices for acrylonitrile as main raw material of the Business Unit Carbon Fibers as well as higher than expected customer demand for acrylic and carbon fibers combined with consistently good production capacity utilization and capability, the management of SGL Carbon SE assumes an improved earnings development of this Business Unit.

SGL Carbon assumes that the factors mentioned will continue at least until the end of the year and that the earnings situation of the Business Unit Carbon Fibers will exceed previous expectations. Combined with the continued good business development of the other three Business Units (Graphite Solutions, Process Technology and Composite Solutions), an improvement in the sales and earnings situation at Group level is expected.

In line with the forecast increase for adjusted EBITDA (EBITDA pre) to between €170 and €190 million (previously: €130 - €150 million), the company is forecasting adjusted EBIT (earnings before interest and taxes and before one-off effects and non-recurring items) of between €110 and €130 million (previously: €70 - €90 million). The forecast for return on capital employed (ROCE) of originally 7% - 9% has been raised to 10% to 12% corresponding to the development of earnings. The expectations for free cash flow (significantly below previous year's level of €111.5 million) remain unaffected by the expected improvement in sales and earnings.

The updated forecast for fiscal 2022 has been prepared on the basis of the currently prevailing market environment and assumes no deterioration in the general conditions, in particular due to the war in Ukraine and its consequences for the global economy.
 
The definition of key figures used in this release is aligned to the Annual Report 2021. There were no changes in the scope of consolidation or accounting methods compared with the previous guidance.

In light of the evolving pandemic circumstances in Shanghai, Cinte Techtextil China will no longer be taking place from 6 – 8 September at the Shanghai New International Expo Centre. A new date for the technical textile fair will be announced in due course.
 
Ms Wendy Wen, Managing Director of Messe Frankfurt (HK) Ltd, explained: “After discussions with stakeholders, and in support of the government’s pandemic control measures, we have decided to postpone Cinte Techtextil China 2022 to a later date. The safety of fairgoers is of paramount importance to the fair’s ongoing success, and we are working tirelessly to provide an efficient sourcing platform for the technical textile industry. I would like to thank all participants for their sustained support and understanding.”

Cinte Techtextil China’s product categories cover 12 application areas, which comprehensively span a full range of potential uses in modern technical textiles and nonwovens. These categories also cover the entire industry, from upstream technology and raw materials providers to finished fabrics, chemicals and other solutions. This scope of product groups and application areas ensures that the fair is an effective business platform for the entire industry. The 2021 edition attracted 366 exhibitors and recorded 14,868 visits. The fair is organised by Messe Frankfurt (HK) Ltd; the Sub-Council of Textile Industry, CCPIT; and the China Nonwovens & Industrial Textiles Association (CNITA).

According to the World Health Organization (WHO), cardiovascular disease is one of the most common natural causes of death. Every year, it is the cause of death of around 17 million people worldwide. The Peter Dornier Foundation Prize 2022 has now awarded a research work that is to improve the medical care of people with insufficient heart valve function in the future and prolong the patients' lives.

The human heart is a high-performance machine: over the course of a person's life, it beats almost three billion times, pumping around 200 million litres of blood through the body. Enormous stresses that can sometimes lead to life-threatening signs of wear and tear. If a heart valve gets out of step, patients usually get artificial-mechanical or biological valves as a replacement. However, mechanical solutions imply patients to take blood-thinning medication for the rest of their lives. In addition, there may be audible closing noises. For example, almost a quarter of patients with mechanical heart valves complain of sleep disturbances. Biological heart valves, on the other hand, such as those made from animal tissue, require a great deal of manual work and have a shorter lifetime.

Potential of weaving for medical products demonstrated
For this reason, Graduate Engineer Mathis Bruns at the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) at the TU Dresden is researching an implant alternative made of fabric. As part of a research project that also involved heart surgeons from the Dresden Heart Centre and the University Hospital in Würzburg, Mr. Bruns provided important findings for weaving an artificial heart valve in his diploma thesis. For his work entitled "Development of tubular structures with integrated valve function", Mathis Bruns has now received the Peter Dornier Foundation Prize 2022, endowed with 5,000 euros. In his laudation, Dr. Adnan Wahhoud, former head of the development department of air-jet weaving machines at DORNIER in Lindau, said: "With his work, the winner of the award demonstrates very clearly the potential of weaving technology to produce fabrics of complex form, geometry and structure with the aim of prolonging and improving people's lives." The award-winning thesis enriches research into three-dimensional tissues for use in medicine.

Weaving replacement heart valves without seams
"A particular advantage of our approach is the integral production method", says foundation prize winner Mathis Bruns. “The geometry and function of a heart valve is that complex that woven heart valves could not be produced in this form previously. Through the combined use of a rigid rapier weaving machine with bobbin shield and a Jacquard machine, it is possible to weave the replacement heart valve in such a way that it no longer has be sewn together. Even the tubular structures for the blood vessels and the integrated valve function are ‘all of one piece’. Seams are always a weak point in textile medical products," Mr. Bruns adds. “Another advantage of the woven heart valve is the possibility to insert it by the help of minimally invasive surgery. Hence, the folded valve which is about the size of a tea light is to be pushed with a catheter via the bloodstream to the target position in the heart and unfolded there. The patient's chest and heart would then no longer have to be cut open”, explains prize winner Mr. Bruns.

Textile structure is similar to human tissue
A wide variety of medical products have always been produced on DORNIER weaving machines. Customers use them to produce fabrics for bandages, prostheses, blood filters and orthoses among other things. For Mathis Bruns, it is only evident that implants such as heart valves will more and more be woven on the machines from Lindau in the future. "Textile tissue is very similar to human tissue," he says. The human body consists largely of thread-like materials, just as a textile fabric is made up of thousands of individual threads. "Muscle fibres convey force impulses, nerve tracts send stimuli such as pain and brain cells convey information via thread-like dendrites and axons." Because of their ‘thread-like properties’, woven implants are therefore particularly suitable for medical applications.

After three years, VUB a.s again got the chance to actively participate in the European trade fair Techtextil 2022m being present at a joint stand of Czech companies active in production and application of technical textiles, organized by Clutex - Cluster Technical Textiles.

In cooperation with partners from academic and production sphere many products were developed over the past years, sold by VUB under the brand Clevertex. For the presentation at the fair, a wide range of ESD protective clothing for the electrotechnical industry and for each worker dealing with electrostatic discharge sensitive components was on display. As well as another product line of the Clevertex brand representing wearable skincare textile products with antiseptic effects based on purely natural textile materials.

Attention was paid to the advanced solutions for smart textiles and e-textiles products esp. electrically conductive hybrid threads based on ultrafine metallic micro-wires. A significant advantage of these threads lies in their full compatibility with standard textile manufacturing processes, and possibility of customization in terms of fineness, electrical conductivity and temperature resistance of individual thread. As an example of one of the applications of conductive threads, different types of woven elastic conductive ribbons were demonstrated, which could be used as bus bars or as textile conductors wherever a variable length of conductive element is required without the negative influence on their electrical resistance during the change the length.

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.

ITM 2022 hosted textile technology leaders in Istanbul for 5 days, presenting the latest innovations in every field of textile from weaving, knitting, yarn, digital printing, finishing to denim. The ITM 2022 Exhibition, where a business volume of over 1.5 billion Euros was created in 5 days, accelerated the Turkish and world economy.

Organized by the partnership of Teknik Fairs Inc. and Tüyap Tüm Fuarcılık Yapım Inc., ITM 2022- International Textile Machinery Exhibition was held at Tüyap Fair and Congress Center between 14-18 June.  ITM 2022 Exhibition, attended by 1280 companies and company representatives from 65 countries, was visited by 64,500 people from 102 countries, consisting of 44% international and 56% domestic visitors.

Turkey became a Supply Center at the ITM 2022 Exhibition
The successful sales graph achieved at the ITM 2022 Exhibition proved that the difficulties experienced due to the pandemic for the last 3 years have been left behind. Turkey has become a supply center for European, Middle Eastern and African countries, especially with the disruption of the supply chain in Far East countries, including China. The profile of the professional visitors visiting the ITM 2022 Exhibition revealed that in the new world order that has shifted after the pandemic, the trade network has also changed hands and new players have appeared on the scene. The fact that manufacturers from all over the world such as Andorra, Angola, Honduras, Peru, Seychelles, Sierra Leone, Brazil, Sri Lanka, Tanzania, Egypt, Iran, and Oman purchased a large number of machinery and signed collaborations at the ITM 2022 Exhibition has proven this.

Exhibitors of ITM 2022 enlarge their stands for ITM 2024
Many company officials, who stated that they have achieved a sales graphic far above their expectations starting from the very first day of the ITM 2022 Exhibition and that they have hosted visitors from all over the world, decided to enlarge their stands at the ITM 2024 Exhibition. During the exhibition, companies visited the registration application points and applied for ITM 2024 participation.

The next meeting of the ITM and HIGHTEX Exhibitions will be held in Istanbul between 4-8 June 2024.
