From the Sector

After two years of joint collaboration and research the Swiss Textile Recycling Project “Texcircle” comes to an end. Partners and stakeholders have worked on the vision of a textile cluster where materials flow in circular loops. The goal of the project was to develop high-quality yarns and products incorporating such a large amount of recycled textiles as possible. In the end, several product prototypes from carpets, socks, and curtains to pullovers, padding and accessories have been developed with at least 50 % recycled fiber up to 80 % recycled fibers and yarns.

Europe has a waste problem of 7.5 million waste of which only 30-35 % is collected and less than 1 % of the textile and clothing worldwide is recycled into textiles and clothing again. It is as well found that around 80 % of the impact of a textile product lies in the design.

Together with the design research expertise of the Lucerne University of Applied sciences and arts, the spinning expertise of Rieter and the sorting and collection expertise of Texaid, systems should be created where products of high quality can be produced of recycled fiber. On board were the expertise of further Cluster partners of Brands, Retailers, and the public sector to see how a joint Cluster and system coukld be established.

The Project Texcircle and cluster is led by the Lucerne University of Applied Sciences and Arts – Art  & Design, and in collaboration with Coop, Rieter, Jacob Rohner AG, Ruckstuhl AG, TEXAID as well as workfashion.com ag. Furthermore, Bundesamt für Zivildienst ZIVI, NIKIN AG, and Tiger Liz Textiles are supporting the project. The project is funded by Innosuisse.

Furthermore, collaboration partners from all over Europe contributed to the project to enable these prototypes and systems.

Through joint developments from the design, the collecting, sorting trials, tearing, and spinning trials until the actual production trials and product testing. The partners were able to recycle 2.5 Tons of pre-and post-consumer textile waste into product prototypes with a promising commercial interest. From socks, west, and pullovers to non-woven felts and accessories to carpets and curtains. Through our 2 years of collaboration, the teamcame across several hurdles in the textile recycling value chain which could be tackled. This was a proof of concept that a circular system is possible and the industry now has to enable this at full scale.

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

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

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

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

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

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

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

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

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

On the occasion of the Techtextil fair in Frankfurt, the Chairman of VDMA’s Walter Reiners-Stiftung Foundation, Peter D. Dornier, has awarded prizes to seven successful young engineers. For the first time, the Foundation awarded two Sustainability Awards. They are awarded to academic works in which, for example, solutions for resource-saving products and technologies are developed.

A Sustainability Prize in the category Project Work, endowed with 3.000 euros was awarded to Simon Hoebel, TU Dresden, for his thesis on recycled thermoplastic fibres for composite components.
Marina Michel, TU Dresden, received a Sustainability Award in the category Master, worth 3.500 euros. The topic of her master thesis was the functionalisation of yarns for the filtration of micro- and nanoplastics from water.

A Promotion Prize in the category Project Work, endowed with 4.000 euros, was awarded to a student group from RWTH Aachen. The teamwork of Luis Gleissner, Leopold Habersbrunner, Frederic Olbrich and Frederik Schicks was the construction of a test rig for tests on oil-adsorbing textiles.

Felix Zerbes, RWTH Aachen, was awarded a Promotion Prize of 3.500 euros in the category Master. He developed a technical solution for air jet weaving to improve the quality of woven fabric.

Trützschler Man-Made Fibers introduces OPTIMA for IDY and expands the range of the OPTIMA extrusion systems by the industrial yarn (IDY) sector. In addition to OPTIMA for carpet yarns (MO40-C, MO40-E and TO40), variants for manufacturing (semi-)industrial multifilament yarns are now joining the line.

Since 2012, Trützschler has been developing and building high-performance extrusion lines for carpet yarns (BCF - Bulk Continuous Filament) and industrial/technical yarns made of polyester, polyamide and polypropylene. The market launch of the OPTIMA concept for BCF took place in 2019 and has established itself in the markets since then. OPTIMA was designed as a modular platform and now also includes solutions in the IDY (InDustrial Yarn) sector.

OPTIMA systems for industrial yarn (TEC-O40 and TEC-O80) impress with flexibility application and end product diversity. Both concepts offer a wide range of design options and can be tailored precisely to meet end product and the throughput requirements.

OPTIMA enables the production of high-tenacity yarns for shoelaces, ropes and nets as well as low-shrinkage qualities for tire cords, truck tarpaulins and airbags. As the lines are modular, they can be quickly adapted to new market developments and end products.

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them 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 technologies 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. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They 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.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding 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 – technological 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.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

Turkish company Altun Tekstil, a manufacturer of home textiles and upholstery fabrics, has ordered a total of five of the latest Orthopac RVMC-15 weft straighteners from Mahlo.

The fully integrated units benefit from universal control technology and the intuitive Mahlo mSmart G15 visualization concept. The HMI has been optimized for userfriendliness. The visualisation concept is constantly enhanced and ready for Industry 4.0. The path to a digital future within Altun is prepared.

Leading Japanese textile solutions provider SHIMA SEIKI MFG., LTD. of Wakayama, Japan will exhibit at the upcoming JEC World 2022 exposition to be held in Paris, France next month.

On display will be the P-CAM®131 multi-ply computerized cutting machine (NC cutting machine). SHIMA SEIKI's fast, efficient and reliable P-CAM® series computerized cutting machines are known for their innovative functions and Made-in-Japan quality, and boast the largest market share in Japan. At JEC World P-CAM®131 is shown in its most compact form, featuring a cutting area of 1,300 mm x 1,700 mm, with option for expansion. Its multi-ply cutting capability allows up to 1 inch (33mm) of fabric or material to be cut. A knife sharpening system produces a sharp, strong blade every time. Strong, robust components permit quicker response times for knife movement and more accurate cutting composites and other industrial materials. The P-CAM® lineup is ideally suited to global production in a wide range of industrial applications in addition to apparel and textiles.

Also available for video 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 because flat knitting as a textile production method is capable of producing end products that are shaped-toform and with added thickness. Therefore, savings in post-processing time, cost, material and labor as compared to current methods of preform production 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.

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.

The next edition of Techtextil North America will take place in Atlanta from May 17^nd to 19^th.  At Atlanta ACIMIT, the Association of Italian Textile Machinery Manufacturers, and Italian Trade Agency organize an Italian Pavilion, where 17 Italian machinery manufacturers involved in the production of machines for technical textiles will show their innovative solutions.

ACIMIT members exhibiting in the Italian Pavilion are: 4M Plants, Aeris, Arioli, Computer House, Fadis, Flainox, Guarneri Technology, Ima, Kairos Engineering, Mcs, Ramina, Siltex, Stalam, Testa, Willy.

The US textile industry is one of the top in US manufacturing sector, with a sales volume of exceeding US$ 64 billion in 2020, with approximately 300,000 workers and about 15,000 companies. The industry's strength lies in cotton, man-made fibers, and a wide variety of yarns and fabrics, including those for apparel and industrial uses.

In 2021, the USA represented the third market for Italian textile machinery exports, behind China and Turkey. In 2021 January-September period the value of Italian sales to US market was 93 million Euros, an increase of 74% compared to the same period of the previous year.

US Vice President Kamala Harris announced significant multimillion-dollar investments by Parkdale Mills and six other companies today, as part of the Administration’s Call to Action to the private sector to promote economic opportunity in the region, as her office works to address the root causes of migration.

Vice President Harris, who is overseeing diplomatic efforts with El Salvador, Guatemala, Honduras, and Mexico, announced several private sector commitments to strengthen economic opportunities in the Northern Triangle and made remarks at a White House roundtable, which included Anderson Warlick, Chairman and CEO of Parkdale Mills. The textile and apparel co-production chain is one of the most essential supply chains for employment and economic development in both the United States and the Northern Triangle region, currently supporting over 1 million jobs in the United States and the Central American region. The Dominican Republic-Central America Free Trade Agreement (CAFTA-DR) and its strong rules of origin are the primary reasons this co-production chain exists, which is seeing significant growth this year.

North Carolina-headquartered Parkdale Mills, one of the largest manufacturers of spun yarn and cotton consumer products in the world, will make a multimillion-dollar investment in a new yarn spinning facility in Honduras and make an additional substantial investment to support existing operations in Hillsville, Virginia. This investment will help customers shift 1 million pounds of yarn per week away from supply chains in Asia and China and enhance U.S. and CAFTA-DR co-production resilience and increase regional product offerings. Parkdale’s announced investment will create hundreds of jobs in Honduras and further support hundreds of employees in Parkdale’s Hillsville operations.  

Recently, administration officials from the U.S. Trade Representative’s office and the Vice President’s office met with the U.S. textile industry to reaffirm the importance of rules of origin in nearshoring production chains, helping address labor and environmental challenges and mitigating supply chain risk.

“I would like to sincerely thank Vice President Harris for making this announcement and leading the effort with private industry to create more economic opportunities in northern Central America and the United States,” said Anderson Warlick, Chairman and CEO of Parkdale Mills. “Parkdale’s investments will support good paying jobs in the United States and in the Central American region and significantly increase our extensive product offering and capacity, including the production of sustainable specialty yarns.

Parkdale sees an enormous opportunity for brands and retailers to re-shore and nearshore production supply chains and double the size of U.S.-CAFTA-DR trade, because of the rules of origin in our trade agreement and a shift in sourcing by brands and retailers mitigating their supply chain sourcing risks.  We are excited about what this opportunity means for jobs in the U.S. and the region for this critical production chain and couldn’t be more thrilled to be part of this effort.  We look forward to working with the Vice President and her team on strengthening the textile and apparel production chains in the U.S. and region.”

National Council of Textile Organizations (NCTO) President and CEO Kim Glas, said, “This is an exciting and important announcement by Parkdale and Vice President Harris. Our industry has invested billions of dollars in the U.S. and in the region as a result of the investment-based rules of origin in the CAFTA-DR agreement, which ensures the job benefits of the agreement are reserved for the parties to the agreement.  Additional substantial announcements on further investment in textile and apparel production are expected soon.

As brands and retailers are seeking more environmentally sustainable, vertically integrated, transparent, and quick turnaround supply chains, our collective industries stand ready to work with companies that are seeking to mitigate sourcing strategies as Asian supply chains have faced enormous production constraints.  Further verticalization in the industry, like Parkdale’s announcement today, allows broader product diversification and grows jobs across the textile and apparel production chain.

We are thrilled with today’s announcement because it is a win-win for American and Central American workers and our environment and a huge opportunity to further recalibrate supply chains out of China and Asia. This valuable co-production chain between the U.S. and the CAFTA-DR region accounts for $12 billion in two-way trade and billions of dollars of investment. Significant growth is occurring in our sector and is expected to continue as supply chains continue to recalibrate.  We are delighted about this today’s announcement and appreciate the Administration’s strong support.”
