From the Sector

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

• Award for near-net-shape 3D meshes for use in fibre-reinforced plastics

As part of the JEC FORUM DACH 2022, the AVK Innovation Awards were presented in Augsburg on November 29th. The innovation price in the category "Research/Science" (first place) was awarded to the team of scientists Dipl.-Ing. Dominik Nuss, Dr.-Ing. Cornelia Sennewald and Prof. Dr.-Ing. habil. Chokri Cherif.

With the development of the pull-off-free Jacquard weaving technology including the technological know-how in the field of highly complex 2D and 3D fabric geometries, which has been established at the ITM of the TU Dresden for many years, Dominik Nuss has succeeded in including different yarn lengths locally into the fabric structure solely through targeted variation of the fabric weave. There-fore, it is now possible to produce completely new types of fabrics without additional draping, especially spherically curved fabrics, but also large-format spiral or even curved fabrics. The fact that the required near-net-shape geometry of the component to be reinforced can be reproduced with significantly reduced preforming steps is to be emphasized.

Continuous simulation aided engineering from CAD design to integrally woven 2D and 3D preforms by means of highly complex weave development for spatial constructions is a unique at the ITM, which was indispensable for the development of these promising woven high-tech structures. This technology is completely new and has never been carried out in this way before. The fabric structures are characterised by a high innovation level due to their geometric diversity and purposes. It can be used in numerous applications and further more contributes to the development of completely new fields of application. The technology can be implemented on all Jacquard weaving machines with only an additional device and the preform geometry is only determined by the control of the Jacquard machine. The preform geometry can be used in the full working width of the weaving machine.

Professor Chokri Cherif, Institute Director of the ITM, and his team are very pleased about these continuous research success in the constantly growing research field of 3D weaving technology, which are achieved at the ITM in close cooperation with industry and users. "This award is a special honour for our institute and confirms that the many years of our excellent research in the field of near-net-shape 3D weaving for the fibre-reinforced plastics sector plays a significant role and that we are making a significant contribution to the sustainable and resource-efficient production of lightweight structures with our development".

These categories also cover the entire industry, from upstream technology and raw materials providers to finished fabrics, chemicals and other solutions.

The identification of profitable new niche markets has been central to the success and continuous expansion of Germany’s Dolinschek, a leading knitting, dyeing and finishing specialist, located in Burladingen in Baden-Württemberg.

“There is so much more to textiles than just clothing,” says Theo Dolinschek, who runs the company with his brother Erwin. “We handle many different technical materials such as automotive components, geotextiles and wallcoverings, but also those for more unusual applications such as inlays for extractor hoods, cut protection fabrics and even wool felts which are employed as insulation on wind turbines.

“We have also recently started to produce compression stockings in a variety of colours, because not everyone wants them black, beige or skin coloured. The most important product areas for us now are in sportswear, corsetry and lingerie, as well as orthopedic and medical products, workwear and protective clothing, but in addition, many other technical applications.”

The Dolinschek brothers moved their business to the historic site of the former Ambrosius Heim textile company in Burladingen in 2001 in order to expand. At the time, the company – founded by their father in 1980 as a textile wholesaler before moving into dyeing – employed just 13 people. Within a year, the company had bought additional space at the site.

Now, with Theo in charge of technology and sales, and Erwin responsible for production, the company employs almost 100 people and operates on an integrated site of 35,000 square metres.

In 2005, a laminating department was established by the company and since 2012 investment in knitting machines has been ongoing.

“The further we went into vertical integration, the more of our own products we were able to position on the market and so we were also able to make ourselves more independent,” says Theo. “We have continued to develop and today we can produce high-quality fabrics for many fields, with 42 knitting machines, 36 dyeing machines, three stenter frames and many other production and processing machines.”

Dolinschek has also developed its own proprietary TMG dyeing machines which have subsequently been successfully sold to many other companies all over the world. There are currently 11 of these machines  in operation at the Burladingen site and around 45 installed at other companies.

For finishing technology, however, the company relies on Monforts, and has installed a new seven chamber Montex TwinAir stenter range with a Montex®Coat coating unit in knife execution, enabling the coating of dimensionally stable knitted fabrics with polyurethane or acrylate. Another unique feature is the Teflon-coated (non-stick) transportation belt through the system.

The Montex line is also equipped with integrated heat recovery and exhaust gas purification to ensure the most resource-efficient processing available on the market. The exhaust air goes from the Monforts heat recovery system into an existing air/water heat recovery system and then into an electrostatic precipitator.

Highly-intuitive Monforts Qualitex visualisation software allows all machine functions and process parameters to be assessed and controlled easily.

Monforts will highlight its technologies for special technical textile applications at this year’s ITMA ASIA + CITME which takes place at the National Exhibition and Convention Center in Shanghai, China, from November 20-24.

One of Monforts' developments is the Montex 8500 XXL stenter system for the production of technical fabrics in widths of up to 6.8 metres. Among the products made on this system are treated nonwovens for the geotextiles and filter media markets, tarpaulins, advertising banners, black-out curtains, membranes and many more.

On Montex©Coat coating lines, meanwhile, the possibilities range from the single-sided application of finishing agents for outdoor clothing and adding functionality to home textiles, to the creation of materials for sophisticated lightweight construction and automotive and aerospace components.

“Many more applications are possible, such as the overdyeing of denim, the creation of double-face coated materials, fabrics awnings, tents and medical drapes and the pre-treatment of substrates for digital printing”, explains Gunnar Meyer, Monforts area sales manager for China. “A range of different doctor blades and their combinations can be supplied to meet individual requirements, including air knife, roller knife, foam, screen and magnetic roller coating. The latter option is recommended for lines with working widths of over 2.4 metres.”

In addition, Monforts can provide the necessary explosion-proof ranges for solvent-based coatings and high temperature processes up to 320°C, such as the PTFE coating of nonwoven filter material. These lines are equipped with special burners, stenter chains, and insulation.

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.

• Biotransformation technology for nonwovens

Avgol^® has received the prestigious Innovation Award at the RIGHT Hygiene conference in recognition of its collaboration with Polymateria in development of pioneering biotransformation technology for nonwovens.
 
Biotransformation is a unique functionality wherein a conventional nonwoven fabric can be modified to react to certain triggers to then begin a cascade, and importantly a fundamental chemical transformation of the polymer resin into a wax that is readily degraded by natural bacteria, microbes and fungi normally found in the environment.
 
“The transformation is triggered through the combined effects of the natural elements of decay - air, moisture, heat and sunlight,” said Mr. Sanjay Bhayani, Director of India Operations with Avgol. “Once triggered, the material will transform into a low molecular weight wax structure leaving no microplastics or toxic residue behind. Moreover, if the product comprising the biotransformation technology is disposed of in the normal way and facilities are available, then it can be recycled by readily available means.”

“By bringing the Biotransformation technology to the various potential markets in India, we hope to offer a real-world solution to waste management,” he said. “We particularly hope to address aspects of the creation of fugitive waste and remove this from the environment without causing additional, and potentially more dangerous, problems.”
