From the Sector

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.

Catering to the acoustic requirements of electric vehicles, Autoneum has extended its concepts for noise-reducing engine encapsulations to new applications related to electric drives. Hybrid-Acoustics PET and the foam-based alternatives Hybrid-Acoustics FLEX and Fit FLEX ensure optimum noise protection in e-cars and thus improve driving comfort. All three technologies are characterized by a high acoustic performance tailored to specific customer needs and zero waste production.

Disturbing noises such as the high-frequency sounds of e-motors and other electric devices or the whining noise of the gearbox are posing new acoustic challenges for vehicle manufacturers worldwide. Anticipating the increasing demand for sound-reducing components in both the front and the rear of e-cars early on, Autoneum has expanded its technologies for noise protection in the engine bay to new tailor-made applications for electric vehicles.

With the fibrous technology Hybrid-Acoustics PET and the two foam alternatives Hybrid-Acoustics FLEX and Fit FLEX, the Company offers three standardized technologies that reduce noise directly at the source, thereby improving driver comfort. All three technologies are produced waste-free and their adaptive capacity to different sizes and shapes allows for a broad spectrum of uses in electric vehicles: from e-motor encapsulations to the reduction of noise and vibration of inverters, gearbox, pumps and compressors. By offering both fibrous and foam-based variants, Autoneum is able to flexibly cater to individual customer needs and preferences with regard to material, acoustic concept, sustainability and costs.

In terms of sustainable noise protection in the engine bay, Autoneum’s patented innovation Hybrid-
Acoustics PET sets the tone: it is made of 100 percent PET with up to 50 percent recycled fibers; cut-offs in production are reclaimed, processed and reused and the material can be fully recycled at the end of product life. The unique textile technology, which is part of the Company’s sustainability label Autoneum Pure, is particularly suited to attenuating high-frequency sounds of the electric drive unit and offers the optimum balance of absorption and insulation. Moreover, components made of Hybrid-Acoustics PET are up to 40 percent lighter compared to standard insulators.

To accommodate the differing preferences of vehicle manufacturers, Autoneum has complemented its lightweight textile technology with two foam-based alternatives. Since the foam is injected in both technologies, no waste is generated during production either. Hybrid-Acoustics FLEX is based on the same acoustic concept as Hybrid-Acoustics PET, but the decoupler is made of foam instead of felt. Autoneum’s Fit FLEX, on the other hand, combines the foam decoupler with an injection molded heavy layer. Thanks to the high geometrical adaptability of foam to even complex shapes, both technologies offer outstanding acoustic performance in the insulation of e-motors and other noise sources in electric vehicles. Furthermore, the absorbing or insulating acoustic quality of the foam can be flexibly tuned to specific customer needs.

Global Organic Textile Standard (GOTS) announces the release of its 2021 Annual Report. Even with the continued constraints of COVID-19, 2021 was a year of significant developments for GOTS. An increased interest in sustainability in the textile industry led to greater awareness of GOTS certification from businesses as well as consumers.

The 31-page report details the record growth experienced in 2021, which included an increase of 19 percent in GOTS certified facilities around the world, with Certification Bodies (CBs) reporting 12.338 facilities in 79 countries (+11 percent). Three new GOTS-approved Certification Bodies brought the total to 18, nine of which have chemical input approval in their scopes. The additional CBs are helping meet an ever-increasing demand for certification. The rise in certifications also allowed GOTS to expand internally, adding Representatives as well as colleagues with expertise in Standard Development and Implementation, Quality Assurance, Communication, and IT. GOTS representatives worldwide offered training and education to thousands of participants, including businesses, governmental representatives, certification bodies, and other stakeholders. Visits to the GOTS website jumped 43 percent from 2020 and GOTS’s following on social media expanded significantly, gaining 57 percent across platforms.

“Despite ongoing difficulties and uncertainty caused by the Covid-19 pandemic, decision-makers continue to pursue their sustainability goals and value GOTS as a tool to accomplish them. We will continue to strive toward our vision of a future in which organic textiles are a significant part of everyday life, enhancing people’s lives and the environment,” says GOTS Managing Director Claudia Kersten.

Additional highlights covered in the report include chronicling the implementation of the most recent update to the standard document, GOTS version 6.0, and the release of ‘Conditions for the Use of GOTS Signs (CUGS)’, which outlines the rules for using the GOTS logo and labeling and updates to GOTS Scope and Transaction Certification policies which are a crucial part of the certification process.

SANITIZED AG, a specialist for hygiene function in textiles, is expanding its Sanitized® Odorex™ portfolio for odorneutralizing technologies.

Sanitized® Odorex™ is the product of several years of experience with environmentally friendly textile treatments. SANITIZED focuses heavily on the causes of, the production of, and the fighting of unpleasant sweat odor in textiles. The basis for the newly introduced biocide-free OX20 product is a metal-free polymer that neutralizes odors. It meets market requirements regarding wash-resistance with excellent results after up to 50 household washes.

Versatile and highly cost-efficient
The new product can be applied in extraction, pad, and spray. It can be used on all common substrates and is compatible with other textile effects. These properties increase the flexibility and efficiency during product design, and they reduce production costs. As one of the first technologies worldwide, OX20 can be applied to synthetics in the dye bath.

Feel and wearing comfort
Binders and particle systems negatively affect the textile’s feel and moisture management. OX20 is a particle-free product with a long-lasting effect that does not change how the textile feels, nor does it affect the textile’s moisture management.

The worldwide leading textile processing standard for organic fibres, Global Organic Textile Standard (GOTS), seeks public input as it begins the revision process for GOTS standard version 7.0.

As a solution for sustainability-related challenges in textile processing, GOTS sets strict and binding requirements regarding ecological and social parameters. These are updated every three years in an open and transparent revision process which fosters constant progress towards the development of better textile processing methods. In this process of continuous improvement, GOTS collaborates with all relevant international stakeholders, including the textile and apparel industry, chemical suppliers, organic farming and environmental organisations, workers' rights groups and labour unions, to ensure ongoing relevance and account for changes in the industry.

The initial period of public input runs from 14 April through 12 June. During this phase, all interested parties, including industry representatives, NGO’s and consumers, are encouraged to participate by submitting comments, feedback, and ideas through GOTS’s online portal.

“We are looking forward to receiving input from stakeholders around the world for GOTS version 7.0. This open call for feedback is part of what keeps our certification requirements up-to-date with the most cutting-edge developments in the industry,” says GOTS Managing Director Rahul Bhajekar.

Beginning in 2022, the revision process will follow the newly developed Standard Setting Procedure, which provides for the constitution of a Standard Revision Committee (SRC) for each revision. This group will serve as the pivotal force behind decisions about the revisions. The SRC consists of experts from different stakeholder groups, including associations, organisations, companies and individuals. All input received by June 12 will be carefully considered by the SRC as well as compiled and made public for an additional 30-day consultation period later this year. All drafts of the standard will also be made public. GOTS standard version 7.0 will be finalised in early 2023, and will be available on the GOTS website.

The timeline for the revision to GOTS version 7.0 is as follows:

1. Constitution of GOTS SRC- April 2022

TEXO AB, a member of TMAS, the Swedish textile machinery association, is currently seeing a surge in demand for its Compfelt weaving looms for press felt base fabrics.

“These are far from standard machines,” explains TEXO President Anders Svensson. “Off-the-shelf industrial weaving machines generally range in their working widths from 1.9 to 3.2 metres, with those purpose-built for technical applications such as geotextiles extending to wider widths of six metres and beyond. Meanwhile, one of the machines we have recently successfully delivered and commissioned has a working width of 23 metres and is not even the widest of the many such machines the company has engineered and delivered worldwide since its formation.”

A second recently-delivered line has a more modest working width – in relative terms – of 13 metres.

Paper machines
The demand for such machines comes from the suppliers of paper machine clothing (PMC) to paper mills, who in turn operate colossal machines for paper manufacturing.
On of the largest paper making machines is currently believed to be located on Hainan Island off the southern coast of China and is 428 metres long – roughly the length of four football pitches. Naturally, such machines require equally large-scale components, which is where TEXO comes in. All paper machines require a regular supply of PMC fabrics which are employed in three separate areas of the paper machine – the forming section, the press section and the drying section.

Press felts
TEXO Compfelt weaving machines are specifically employed for the production of endless (tubular) woven base fabrics for the press section of paper machines, where water is mechanically removed from the newly formed sheet of fibres. In the simplest press, the sheet is carried by the PMC fabric between two rolls, where water is squeezed out by the application of load and pressure. This can also be assisted by the use of vacuum and heat. The PMC fabrics here need to be replaced regularly, with a maximum lifespan of six months.

Press felts have become increasingly sophisticated over the years, consisting of complex woven base structures which are subsequently combined with nonwovens via needlepunching on equally huge machines. The woven base fabrics are primarily made from polyamide for its strength and hygroscopic and elastic properties.

Dobby harness
“A major refinement of the machine has been the ability to equip it with up to 24 dobby harness frames to meet the demand for sophisticated structures from the PMC manufacturers. Although the PMC business represents a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates.”

Another significant development has been that of a self supporting base pre-filled with concrete, which has eliminated the need to dig out foundations in a plant to support the machine.

Retrofits
TEXO’s looms are built to last, but technology moves forward, and the company is also currently active in the retrofitting of existing machines built as far back as the 1970s.

Integration
TEXO has also just integrated its offices and production centre at its base in Älmhult, Sweden, to create a unified 5,000 square metre site.
