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.

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.”

Oerlikon Polymer Processing Solutions at the Techtextil India 2023

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.

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.

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.

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.”

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.

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.

Swiss Textile Machinery technology and innovations for technical textiles

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.

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.

SHIMA SEIKI to exhibit at Techtextil 2022 in Frankfurt

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, along with its Italian subsidiary SHIMA SEIKI ITALIA S.p.A., will be participating in the Techtextil exhibition in Frankfurt, Germany from the 21st till the 24th of June 2022.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, along with its Italian subsidiary SHIMA SEIKI ITALIA S.p.A., will be participating in the Techtextil exhibition in Frankfurt, Germany from the 21st till the 24th of June 2022.

On display will be SHIMA SEIKI’s latest innovation in flat knitting technology as applied to the field of technical textiles—a prototype weft knitting machine capable of multi-axial yarn insertion. Fabrics produced on this machine use inlay technique for the production of hybrid textiles that combine the stretch characteristics of knitted fabrics with the stability of woven textiles, suited to various technical applications. To this, warp yarn is inserted to further expand its capability to produce 3D-shaped carbon fiber and composite preforms directly on the machine. This is made possible by taking advantage of the fact that flat knitting as a textile production method is capable of producing end products that are shaped-to-form and with added thickness. Compared to current methods of preform production, savings in post-processing time, material, labor and associated costs are immense, realizing efficient and sustainable production. SHIMA SEIKI’s own yarn unwinding technology is also used for optimum yarn feed and tension for use with technical yarns that are otherwise difficult to knit. Industrial textile samples knit on the multi-axial machine will also be available for examination on-site.

SHIMA SEIKI's SDS®-ONE APEX4 3D design system will be available for demonstrations as well. Of particular interest should be its ultra-realistic simulation capability that realizes Virtual Sampling. When countless variations must be evaluated before arriving at a final design, virtual product samples can be used to streamline the decision-making process by minimizing the enormous amount of time, cost and material normally associated with producing actual samples for each variation. When approved, the same data can be converted to machine data for immediate knitting, significantly reducing lead times.

Swiss Textile Machinery members at Techtextil

High-performance yarns now offer almost unlimited possibilities for replacing traditional raw materials in a vast range of technical applications. Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ – finding new uses in sectors such as automotive, aviation, maritime, medical and construction, among many others.

Technical textiles are everywhere in our daily lives today, even if we may not always realize it. Some are in more obviously textile products, from sewing threads to artificial turf. But then, take cars as an example: modern vehicles are stuffed with parts made from sophisticated yarns. It’s common for producers of automotive parts now to send template material and requirement lists to Swiss Textile Machinery members, trusting their expertise and experience. Members operate development and testing centers with latest machine installations, where their experts devise customized solutions, as well as calling on the pure innovative spirit which is part of their DNA.

At the extremes
Technology drives applications beyond our current imagining in the case of Heberlein air splicers. Developed for a wide range of uses with high-strength technical fibers, they have no problems splicing aramid fibers up to 16’100 dtex, carbon up to 30’000 dtex, Dyneema up to 5’500 dtex, and glass up to 4’800 tex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of material without interfering knots.

Retech has the technology to achieve specifications for filament yarns, drawing and stretching fibers to perfection. Top heated godet rolls – many customized – are developed for high-performance fibers. Temperatures up to 400 °C can be achieved. Combining the right settings and wide speed ranges for each specific process results in unique end-products.

Fabric producers of high-end applications must avoid any quality risk. Yarn producers are well aware of this responsibility, so they use precision package winders for technical yarns, developed by Rieter’s subsidiary SSM. Taking yarns from ring twisting bobbins, its specialist finish winders can produce coarse-count technical yarns up to 50’000 dtex, offering a new level of flexibility and winding quality.

Lifestyle essentials
At first glance, motorists might fail to notice many of the technical yarns ‘hidden’ inside their cars. These products have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour, for example, arises from the choice of textile material and the special construction of the yarns used.

Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are needed for vehicle products such as tire carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.

Technical yarns also play a surprising role in our mobile devices. Tapping, scrolling and swiping are second nature for billions, with our phones and a plethora of other lifestyle essentials. Yet, how many people would know that the touch-sensitivity we take for granted on these screens is largely made possible by twisted glass fibers. Bräcker, part of Rieter’s components business, offers a selection of vertical sinter metal rings and nylon travelers for glass fiber twisting, so that mills can achieve high levels of productivity and quality.

Future unlimited
Automotive and communication technology are already important industries for Swiss Textile Machinery members, along with well-known technical textiles markets in sectors such as medical, transport and construction. Smart-wear is already noted as a field with significant potential. Naturally, members are constantly investigating other possibilities. Swiss textile machinery is already applied in energy (batteries), and plastics.

The Swiss Textile Machinery Pavilion will be at the Techtextil exhibition in Frankfurt, Germany, taking place from 21 to 24 June 2022.
