TMAS: Digitised solutions at Techtextil and Texprocess

Members of TMAS – the Swedish textile machinery association – will display technologies in alignment with the theme of digitalisation at the forthcoming Techtextil and Texprocess 2024 exhibitions, taking place in Frankfurt from April 23-26th.

Automatic handling
The fully automated and digitised handling solutions for finished garments, home textiles and furniture of Eton Systems, for example, will be demonstrated at Texprocess.

Designed to increase value-added time in production by eliminating manual transportation and minimising handling, the individually addressable product carriers are fully managed and controlled by the latest ETONingenious™ software. This web based real-time data collection and information system continuously accumulates, processes and makes all production information instantly available to supervisors, quality control personnel and management.

This web based real-time data collection and information system continuously accumulates, processes and makes all production information instantly available to supervisors, quality control personnel and management.

Bespoke seams
Svegea will demonstrate its EC 300-XS colarette technology, which is used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements.

The EC 300-XS collarette cutter on show in Frankfurt is equipped with the latest E-Drive II system providing the operator with a very user-friendly touchscreen, providing full control of the cutting process. An accompanying FA 350 fully automatic roll slitting machine will also be demonstrated.

Digital finishing
At Techtextil meanwhile, Baldwin Technology Co. will provide full details of how its highly digitised TexCoat G4 non-contact spray technology for textile finishing and remoistening not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to customer requirements in terms of single and double-sided finishing applications.

TexCoat G4 can reduce water consumption and chemical usage by as much as 50% compared to traditional padding application processes.

Yarn tension
Celebrating its 60th anniversary this year, Eltex will display the latest Eltex EyETM system for the continuous monitoring of yarn tension on warp beams.

The Eltex EyETM eliminates problems when warping, and also in subsequent weaving or tufting processes, monitoring the yarn tension on all positions in real-time and enabling a minimum and maximum allowable tension value it be set. If any yarn’s tension falls outside these values the operator can be warned or the machine stopped.

The Eltex ACT and ACT-R units meanwhile go beyond yarn tension monitoring to actually control yarn tension. This extends the application range greatly. The plug and play system automatically compensates for any differences in yarn tension that arise, for example from irregularities in yarn packages.

Accumulated know-how
Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of Vandewiele Group, supplying weft yarn feeding and tension control units for weaving looms to the majority of weaving machine manufacturers. It also retrofits its latest technologies to working mills to enable instant benefits in terms of productivity and control.

The company will present its latest X4 yarn feeders with integrated accessory displays (TED) as a new standard, as well as launching its own e-commerce platform – iroonline.com.

The TED function enables weft tension settings to be transferred from one machine to another, enabling a fast start-up the next time the same article is woven. The position of the S-Flex Tensioner is constantly monitored by an internal sensor – even if adjustment is made during power off.

X4 feeders are also available with integrated active tension control (ATC-W) as an option. With the ATC-W active tension control, the required tension is easily set and monitored on the integrated display. Once set, the system constantly regulates itself, ensuring consistent yarn tension during the weaving process which is constantly and accurately measured by the ATC sensor unit, sending a signal to the ATC operator unit resulting in consistently stable yarn tension at the required level.

KARL MAYER GROUP: Natural fibre composites and knit to shape products at JEC World 2024

At this year's JEC World 2024 from 5 to 7 March, KARL MAYER GROUP will be exhibiting with KARL MAYER Technical Textiles and its STOLL Business

One focus of the exhibition will be non-crimp fabrics and tapes made from bio-based yarn materials for the reinforcement of composites.

"While our business with multiaxial and spreading technology for processing conventional technical fibres such as carbon or glass continues to do well, we are seeing increasing interest in the processing of natural fibres into composites. That's why we have a new product in our trade fair luggage for the upcoming JEC World: an alpine ski in which, among other things, hemp fibre fabrics have been used," reveals Hagen Lotzmann, Vice President Sales KARL MAYER Technische Textilien.

The winter sports equipment is the result of a subsidised project. The hemp tapes for this were supplied by FUSE GmbH and processed into non-crimp fabrics on the COP MAX 5 multiaxial warp knitting machine in the KARL MAYER Technical Textiles technical centre.

DITF: Biopolymers from bacteria protect technical textiles

Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example wind and water proof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

However, these consume exhaustible resources and the materials can end up in the environment if handled improperly. Therefore, the German Institutes of Textile and Fiber Research Denkendorf (DITF) are researching materials from renewable sources that are recyclable and do not pollute the environment after use. Polymers that can be produced from bacteria are here of particular interest.

These biopolymers have the advantage that they can be produced in anything from small laboratory reactors to large production plants. The most promising biopolymers include polysaccharides, polyamides from amino acids and polyesters such as polylactic acid or polyhydroxyalkanoates (PHAs), all of which are derived from renewable raw materials. PHAs is an umbrella term for a group of biotechnologically produced polyesters. The main difference between these polyesters is the number of carbon atoms in the repeat unit. To date, they have mainly been investigated for medical applications. As PHAs products are increasingly available on the market, coatings made from PHAs may also be increasingly used in technical applications in the future.

The bacteria from which the PHAs are obtained grow with the help of carbohydrates, fats and an increased CO2 concentration and light with suitable wavelength.

The properties of PHA can be adapted by varying the structure of the repeat unit. This makes polyhydroxyalkanoates a particularly interesting class of compounds for technical textile coatings, which has hardly been investigated to date. Due to their water-repellent properties, which stem from their molecular structure, and their stable structure, polyhydroxyalkanoates have great potential for the production of water-repellent, mechanically resilient textiles, such as those in demand in the automotive sector and for outdoor clothing.

The DITF have already carried out successful research work in this area. Coatings on cotton yarns and fabrics made of cotton, polyamide and polyester showed smooth and quite good adhesion. The PHA types for the coating were both procured on the open market and produced by the research partner Fraunhofer IGB. It was shown that the molten polymer can be applied to cotton yarns by extrusion through a coating nozzle. The molten polymer was successfully coated onto fabric using a doctor blade. The length of the molecular side chain of the PHA plays an important role in the properties of the coated textile. Although PHAs with medium-length side chains are better suited to achieving low stiffness and a good textile handle, their wash resistance is low. PHAs with short side chains are suitable for achieving high wash and abrasion resistance, but the textile handle is somewhat stiffer.

The team is currently investigating how the properties of PHAs can be changed in order to achieve the desired resistance and textile properties in equal measure. There are also plans to formulate aqueous formulations for yarn and textile finishing. This will allow much thinner coatings to be applied to textiles than is possible with molten PHAs.

Other DITF research teams are investigating whether PHAs are also suitable for the production of fibers and nonwovens.

The objects range from medical products and high-tech sportswear to smart textiles with integrated sensors. Sustainability activities are also part of the repertoire, such as the production of yarns from recycled waste.

Knitwear Lab operates at two locations for its diverse tasks: Almere in the Netherlandsis available for development work. In Istanbul, there is a branch for production. Both Knitwear Lab sites each have five STOLL flat knitting machines, including models from the modern ADF range. Prototypes are produced in Almere and there is small-scale production. The production plant in Istanbul specializes in the manufacture of high-quality knitwear in small quantities. STOLL is also involved in the creative processes. For the industrial development of knitwear, Knitwear Lab offers Virtual Knitting, a revolutionary method that combines virtual and physical elements of pattern development and knitwear production to reduce waste and pre-production steps. Customers can use Virtual Knitting to create realistic, producible collections, simplify their design iteration processes and take advantage of the wide range of real-life colorways. The basis for this is comprehensive knitwear expertise, the latest 3D software and the CREATE PLUS patterning software, which was developed by STOLL together with KM.ON.

"The 3D visualization of CREATE simplifies communication with the customer considerably. We use this function every day," says Annika Klaas, Senior Knitwear Programmer. She personally appreciates the uncomplicated grading and exchange of stitch dimensions and the much faster and more efficient work with Dimensioned Shapes that this makes possible. This helps her in her day-to-day work. "We often have requests to realize the same product in different yarns, which now works much faster," says the programmer. Further simplifications would include minor optimizations in terms of the efficiency and user-friendliness of programming and additional import and export options for shapes. Discussions on implementation are already underway.

Hologenix: CELLIANT® as a printed coating

Hologenix has announced that its flagship product CELLIANT® infrared (IR) technology, a natural blend of IR-generating bioceramic minerals, is now more widely available from the company as a printed coating, expanding the uses of the technology and increasing the number of prospective partners. The innovation has already been named a Selection in the Fibers & Insulations Category of the ISPO Textrends Awards just last month.

Traditionally, CELLIANT has been embedded directly into fibers and yarns. However, for its print applications, CELLIANT fine mineral powder can be easily added directly onto the surface of all different fabric types. The company is particularly energized about how this expands the array of sustainable offerings that CELLIANT can be incorporated into, and is looking forward to partnering with brands to print CELLIANT on their ecofriendly fabrics. CELLIANT Print may be a cost-effective alternative to in-yarn solutions and allows for a more efficient supply chain.

fabrics or to a new fabric to create a variety of different product applications. For brands who are seeking a smaller pattern roller for apparel, orthopedic products or other close-to-skin projects, CELLIANT Print can accommodate this. There is also a larger pattern roller for bedding and larger-scale applications. As long as the print covers 80% of the fabric’s surface, the design possibilities for the print itself are virtually endless. CELLIANT Print has undergone mechanical testing for wash tests and can be confirmed to last the useful life of the product, for 50+ washes.

By applying CELLIANT Print directly onto the fabric, brand partners are able to use CELLIANT with a higher loading of bioceramic minerals than what would otherwise be possible with an in-yarn solution. This makes it ideal for recovery and performance purposes. In fact, an example of a CELLIANT Print application on kinesiology tape, KT Tape® PRO Oxygen™ was launched in April to great success.

DITF: Lignin coating for Geotextiles

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Textiles are a given in civil engineering: they stabilize water protection dams, prevent runoff containing pollutants from landfills, facilitate the revegetation of slopes at risk of erosion, and even make asphalt layers of roads thinner. Until now, textiles made of highly resistant synthetic fibers have been used for this purpose, which have a very long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade in the soil when it has done its job. Environmentally friendly natural fibers, on the other hand, often decompose too quickly. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are developing a bio-based protective coating that extends their service life.

Depending on humidity and temperature, natural fiber materials can degrade in the soil in a matter of months or even a few days. In order to significantly extend the degradation time and make them suitable for geotextiles, the Denkendorf team researches a protective coating. This coating, based on lignin, is itself biodegradable and does not generate microplastics in the soil. Lignin is indeed biodegradable, but this degradation takes a very long time in nature.

Together with cellulose, Lignin forms the building materials for wood and is the "glue" in wood that holds this composite material together. In paper production, usually only the cellulose is used, so lignin is produced in large quantities as a waste material. So-called kraft lignin remains as a fusible material. Textile production can deal well with thermoplastic materials. All in all, this is a good prerequisite for taking a closer look at lignin as a protective coating for geotextiles.

Lignin is brittle by nature. Therefore, it is necessary to blend the kraft lignin with softer biomaterials. These new biopolymer compounds of brittle kraft lignin and softer biopolymers were applied to yarns and textile surfaces in the research project via adapted coating systems. For this purpose, for example, cotton yarns were coated with lignin at different application rates and evaluated. Biodegradation testing was carried out using soil burial tests both in a climatic chamber with temperature and humidity defined precisely according to the standard and outdoors under real environmental conditions. With positive results: the service life of textiles made of natural fibers can be extended by many factors with a lignin coating: The thicker the protective coating, the longer the protection lasts. In the outdoor tests, the lignin coating was still completely intact even after about 160 days of burial.

Textile materials coated with lignin enable sustainable applications. For example, they have an adjustable and sufficiently long service life for certain geotextile applications. In addition, they are still biodegradable and can replace previously used synthetic materials in some applications, such as revegetation of trench and stream banks.

Thus, lignin-coated textiles have the potential to significantly reduce the carbon footprint: They reduce dependence on petroleum-based products and avoid the formation of microplastics in the soil.

Further research is needed to establish lignin, which was previously a waste material, as a new valuable material in industrial manufacturing processes in the textile industry.

The research work was supported by the Baden-Württemberg Ministry of Food, Rural Areas and Consumer Protection as part of the Baden-Württemberg State Strategy for a Sustainable Bioeconomy.

Sitip fabrics to feature at "Sculpture by the Sea" in Australia

On display at Sculpture by the Sea, the land art event that brings the Sydney coastline to life every year, is “Seabilia”, Elena Redaelli’s latest work created using waste fabric from Sitip’s production processes. A creation that draws attention to the environment and its fragility in the face of human activity, “Seabilia” is a reminder of how precious yet delicate this balance is, and how humans must become mindful of their actions before the effects end up being completely irreversible.

Sitip's commitment to environmental sustainability struck a chord with Elena Redaelli, and a meeting between the Bergamo-based textile company and the artist from Erba, Italy, led to “Seabilia”, a work that will be displayed as part of Sculpture by the Sea on Tamarama Beach near Bondi in Sydney.

It’s one of the most popular events to take place in this corner of Australia, attracting half a million visitors who flock to these Aussie beaches to admire more than one hundred works created by artists from all over the world.

It’s one of the most popular events to take place in this corner of Australia, attracting half a million visitors who flock to these Aussie beaches to admire more than one hundred works created by artists from all over the world.

Held since 1997, this event captures the imagination of its visitors for three weeks each austral spring and, thanks to the vast area it covers, has earned the title of largest annual sculpture exhibition in the world.

The 2023 edition, scheduled to take place from 20 October to 6 November, will feature Elena Redaelli's work created using waste Native-Cosmopolitan Kyoto fabric which, having failed the company's quality control tests, was donated to the artist.

A post-consumer recycled circular knit fabric composed of 89% recycled polyester (PLR), 11% elastane (EA), and weighing 240 grams, the Native-Cosmopolitan Kyoto is made from recycled yarns derived from plastic waste that’s been recovered from the environment, particularly from the sea and from recycling centres. The fabric is Bluesign, GRS (Global Recycled Standard) and OEKO-TEX certified, attesting to Sitip's commitment to environmental responsibility and protection.

During the process, the artist hand-cut the waste fabric and crocheted the pieces together using recycled cotton and other types of thread.

In the creative mind of the artist, the genesis of “Seabilia” arose from deep in the ocean where tiny creatures inhabit the darkest, least explored parts of the planet. A place where the rhythm of life for the inhabitants is marked by silence and obscurity, while waves and tides agitate the surface above. The life of the ocean, such a vast and imposing environment, is impacted every single day by human activity, slowly weakening its delicate balance. “Seabilia” is intended to act as a reminder of how precious yet extremely fragile this balance is, and how humans must become more aware of the consequences of their actions before it’s too late and such a vital asset is lost forever.

“Following Emersione, a work that was exhibited at the Ex Ateneo in Bergamo during Fiber Storming, a textile art exhibition organised by ArteMorbida Textile Arts Magazine and curated by Barbara Pavan, Seabilia is the second art project where I’ve had the opportunity to utilise SITIP's fabrics. – explains the artist, Elena Redaelli. As it was going to be displayed on the rocks at Tamarama Beach, my installation needed a durable, elastic fabric with structural characteristics capable of withstanding ocean winds and sudden changes in weather. Using waste Native-Cosmopolitan Kyoto fabric was the obvious choice, not just because of its very high quality, but also, and more importantly, because it’s made from recycled yarns derived from plastic waste that’s been recovered from the environment, often even from the sea itself. The different textures and shades of white enabled me to create a varied work that, despite the almost monochromatic tones, conjures a diverse range of tactile sensations. The biomorphic modular composition evokes skeletons of sea creatures that appear to have been deposited onto the rocks by a wave and left there to wither in the blazing Australian sun.”

At this year’s Techtextil India, the Polymer Processing Solutions Division of the Swiss Oerlikon group will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Between September 9 and 12, the discussions at Jio World Convention Centre (JWCC), Mumbai, will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
The yarns used in airbags are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technol-ogies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants - without any loss of function in any climate and for the lifetime of the vehicle

Buckle up!
Seat belts have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments. “With our unique, patented Single Filament Layer Technology, we offer a sophisticated and simultaneously gentle high-tenacity (HT) yarn process for manufacturing these lifesavers and other applications made from industrial yarn”, explains André Wissenberg, Head of Marketing.

Road reinforcement using geotextiles
Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demand-ing tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC –  quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

DITF: Textile structures regulate water flow of rain-retaining "Living Wall"

Climate change is causing temperatures to rise and storms to increase. Especially in inner cities, summers are becoming a burden for people. While densification makes use of existing infrastructure and avoids urban sprawl, it increases the amount of sealed surfaces. This has a negative impact on the environment and climate. Green facades bring more green into cities. If textile storage structures are used, they can even actively contribute to flood protection. The German Institutes of Textile and Fiber Research (DITF) have developed a corresponding "Living Wall".

The plants on the green facades are supplied with water and nutrients via an automatic irrigation system. The "Living Walls" operate largely autonomously. Sensory yarns detect the water and nutrient content. The effort for care and maintenance is low.

The plants on the green facades are supplied with water and nutrients via an automatic irrigation system. The "Living Walls" operate largely autonomously. Sensory yarns detect the water and nutrient content. The effort for care and maintenance is low.

Innovative hydraulic textile structures regulate water flow. The rock wool plant substrate on which the plants grow has a large volume in a small space thanks to its structure. Depending on how heavy the precipitation is, the rainwater is stored in a textile structure and later used to irrigate the plants. In the event of heavy rainfall, the excess water is discharged into the sewage system with a time delay. In this way, the "Living Walls" developed at the DITF help to make efficient use of water as a resource in post-densified urban areas.

The research project also scientifically investigated the cooling performance of a green facade. Modern textile technology in the substrate promotes the "transpiration" of the plants. This creates evaporative cooling and lowers temperatures in the surrounding area.

The work of the Denkendorf research team also included a cost-benefit calculation and a life-cycle analysis. Based on the laboratory and outdoor studies, a "green value" was defined that can be used to evaluate and compare the effect of greening buildings as a whole.

In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

Hologenix: Infrared technology with potentially positive impact on diabetic patients

The diabetic community has always been a priority for Hologenix, creators of CELLIANT® infrared technology, so the company embarked on an initial study to test the hypothesis that the technology can positively impact diabetic patients with vascular impairment, now published in Journal of Textile Science & Engineering. Another study is underway as well with more research on the horizon.

The diabetic community has always been a priority for Hologenix, creators of CELLIANT® infrared technology, so the company embarked on an initial study to test the hypothesis that the technology can positively impact diabetic patients with vascular impairment, now published in Journal of Textile Science & Engineering. Another study is underway as well with more research on the horizon.

According to statistics cited in the International Diabetes Federation Diabetes Atlas, 9th edition, globally, close to a half billion people are living with diabetes and that number is expected to increase by more than 50 percent in the next 25 years.
 
The introduction of the study in the Journal of Textile Science & Engineering also reports that diabetic patients frequently suffer from a combination of peripheral neuropathy and peripheral artery disease, which particularly affects their feet. It further states that it has been estimated that the lifetime risk for the development of foot ulcers in diabetic patients can be as high as 25 percent and that the risk of amputation is 10 to 20 times higher than in non-diabetic subjects.
 
The study was performed by Lawrence A. Lavery, D.P.M., M.P.H., a Professor in the Department of Plastic Surgery at UT Southwestern Medical Center. His clinic and research interests involve diabetic foot complications, infections and wound healing, and he participated in the conception, design, implementation and authorship of the Journal of Textile Science & Engineering study.  

CELLIANT technology is a patented process for adding micron-sized thermo-responsive mineral particles to fibers, in this case polyethylene terephthalate (PET) fibers. The resulting CELLIANT yarns were woven into stockings and gloves containing either 82% CELLIANT polyester, 13% nylon and 5% spandex or for the placebo, 82% polyester with no CELLIANT, 13% nylon and 5% spandex. CELLIANT products absorb body heat and re-emit the energy back to the body as infrared energy, which is non-invasive and increases temporary blood flow and cell oxygenation levels in the body.

The objective of the study was to “evaluate changes in transcutaneous oxygen (TcPO2) and peripheral blood flow (laser Doppler, LD) in the hands and feet of diabetic patients with vascular impairment when CELLIANT gloves and stockings are worn.” While there was not a statistically significant result across all subjects, the study did show that some patients wearing CELLIANT stockings for 60 minutes had an increase of as much as 20% in tissue oxygenation and 30% in localized blood flow. According to the study’s conclusion, “the trends that were observed in favor of CELLIANT stockings suggest that a larger well-designed clinical trial should be undertaken and may provide evidence of clinical efficacy in treatment of the diabetic foot.”
 
The study also notes that “There have been no documented or observed side effects of wearing CELLIANT stockings, and they are relatively inexpensive compared to conventional pharmaceutical interventions.”

Hologenix has embarked on a more comprehensive trial, “Study to Evaluate CELLIANT Diabetic Medical Socks to Increase Tissue Oxygenation and Incidence of Complete Wound Closure in Diabetic Foot Wounds” – NCT04709419, which focuses on the impact of CELLIANT technology to potentially improve tissue oxygenation and wound healing outcomes.
 
“We are excited to explore whether future studies of infrared, with its most common biological effects of increased localized blood flow and cellular oxygenation, could result in a breakthrough in diabetic patients with vascular impairment,” said Seth Casden, Hologenix Co-founder and CEO. “We see a huge potential opportunity with this research for helping to fulfill our core mission of improving people’s health and well-being by potentially reducing the impact of diabetes, and we are actively seeking partners to expand our research efforts.”

Polartec®: New technology reduces fiber fragmentation in laundering tests

  • Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.

AVK Innovation Award 2022 to young engineers from ITM at TU Dresden

  • 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".

OCSiAl: Graphene nanotubes expand textiles’ functionality

  • ESD protection in harsh environments:
  • Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
  • Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
  • Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.
