• Bio circular Fibre - Shaping Sustainable Living

The European staple fibre producer Beaulieu Fibres International turns the spotlight on future-focused solutions for nonwovens & engineered fabrics at Techtextil 22. A key priority is innovation in polyolefin fibres and bicomponent polyester/polyolefin fibres, to advance sustainable design, end-of-life recyclability, and resource and carbon footprint reduction for industrial and hygiene applications.

The new sustainability roadmap - Route 2030 outlines how the company is targeting the reduction of our environmental footprint to zero, taking care of people and doing business in a transparent, ethical way. Sustainability is key to Beaulieu Fibre International’s long-term strategy, and the company is heavily focused on defining its green portfolio to support evolution in diverse market applications and to work towards a circular economy with the whole supply chain.

Beaulieu Fibres International will offer ISCC Plus (International Sustainability and Carbon Certification Plus) certified bio circular MONO-PP and BICO PP/PE fibres in 1,3-8,9 dtex, available with all the main available finish classes. These drop-in solutions, with no loss in quality, will support customers reduce reliance on virgin fossil carbon in their nonwoven and engineered fibre applications, contributing to the transition towards a circular economy.

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Baldwin, a leading global manufacturer and supplier of precision spray systems and technology for sustainable textile manufacturing, announce a new collaboration to optimize performance and resource saving in the finishing department.

The two companies aim to support textile manufacturers in their development projects, targeting to improve their product safety, performance and functionality, while at the same time maximizing the productivity and resource utilization of the finishing application process.

Archroma and Baldwin are collaborating in multiple projects that combine Archroma’s most sustainable product innovations with Baldwin’s Texcoat G4.

TexCoat G4 is a non-contact spray technology for textile finishing and remoistening, designed to allow a controlled and optimal coverage of the exact amount of finish chemistry for reaching specific characteristics of the fabric. The system can be used to reduce water consumption by as much as 50% compared to traditional padding application processes.

Archroma and Baldwin are currently testing Archroma’s finishing products and systems, such as the soon-to-be-launched PFC-free* Smartrepel® Hydro SR for water-based soil repellence, as well as metal and inorganic particle-free antimicrobial technologies like Sanitized T 20-19 and TH 15-14, which will be launched at the upcoming Techtextil 2022.

The first test results will be available for discussions with both partners at Techtextil at their respective booths.

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.

The German machinery producer BRÜCKNER used exactly these chances and repositioned itself during the pandemic period. For more than 70 years, the family-run company has been specialized in individual finishing concepts for textiles, technical textiles, nonwovens and floor coverings. The current challenges in the textile industry are serious. The clear increase of the energy costs and the general uncertainty of the energy supply as well as political requirements make a profitable textile production more and more demanding for many companies.

The company responds to this with a newly developed stenter concept with double heating system. Depending on availability, the lines can be operated with gas or oil, but also other combinations with steam or renewable energies are possible. This means that production delays and machine downtimes can be avoided as far as possible. In addition, developed intelligent assistance systems for its machines have been developed that support the machine operator in using the best possible process to operate the line as energy-efficiently as possible. Further energy savings are possible with new energy-efficient motors or heat-recovery and exhaust air cleaning systems. This also helps to avoid harmful emissions.

But many textile producers are also focusing on reducing chemicals. For this purpose, BRÜCKNER's further developed ECO-COAT minimum application unit can make a decisive contribution. Knitted and woven fabrics, but also nonwovens can be finished on one or both sides via different fabric paths. With the minimum application via an engraved roller, a single-sided application of up to 100 g/m² can be achieved. A double-sided and higher application quantity is achieved, for example, by impregnation in the nip. Irrespective of the selected fabric path, a very small liquor reservoir means that only minimal quantities of waste water are produced when changing batches or liquors, and the use of chemicals can also be significantly reduced. In addition, less water has to be evaporated in the subsequent drying process than, for example, in the case of impregnation in a water bath, so the energy requirement is significantly reduced.

On the two upcoming trade fairs ITM in Istanbul and TECHTEXTIL in Frankfurt in June, interested customers can personally get an idea of BRÜCKNER's new developments.

International technology group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at Techtextil in Frankfurt from June 21 to 24. The ANDRITZ product portfolio covers state-of-the-art nonwovens and textile production technologies, such as air-through bonding, airlay, needlepunch, spunlace, spunbond, wetlaid/WetlaceTM, converting, textile finishing, recycling, and natural fiber processing. For Techtextil, special focus lies on technologies for textile recycling, needlepunch, airlay, wetlaid glass fibers and textile calendering.

TEXTILE RECYCLING TECHNOLOGIES BASED ON TEARING
With the acquisition of ANDRITZ Laroche SAS, ANDRITZ has expanded its product portfolio to include airlay and recycling technology as well as bast fiber processing technologies. Complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end-uses are one focus of this product range. Customer awareness and regulations are forcing clothing brands to recycle their textile waste in their own products. Recycled fibers can also be used in the nonwovens industry for various applications, for example in the automotive industry, for insulation, mattresses, and furniture felts.

ANDRITZ Laroche offers a complete process range of tearing lines from 50 up to 3,000 kg/h, which can be used for almost all types of pre/post-consumer textile waste. The aim is to preserve the character of the original fibers, for example cotton, by maximizing fiber length, strength and feel.

At Techtextil from 21-24 June in Frankfurt, Mahlo will be demonstrating how manufacturers of technical textiles can optimise their production even further using measuring and control technology.

Special straightening technology for technical textiles
Mahlo's range also includes solutions for straightening distorted goods. Best suited for technical textiles are, for example, the symbol of the straightening machine, the Orthopac RVMC-15 and the reinforced version Orthopac GRVMC-15. Frame, bearings, and rollers are designed for high loads and allow large working widths of up to 5,400 mm. As the latest development from Mahlo, the experts present the Orthopac CRVMC-15 automatic straightener, which is particularly interesting for the glass & carbon fabric industry and some special applications.

The Mahlo team will present the wide portfolio of intelligent scanners and sensors that record product and process parameters, such as distortion, fabric temperature, dwell time, basis weight, coating weight, thickness, moisture content, residual moisture, exhaust moisture, air permeability, etc. online. Among other things, visitors can expect to see the Famacont PMC-15 weft density measurement system in live operation. The system measures the weft or course density on the running web and compares it with the target value stored in the recipe data management system. The detected deviation from the target value is used to fully automatically control the overfeed during the needling process at the stenter frame and to ensure a constant weft/course density over the full width of the product.

• 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.

The Saxon Textile Research Institute (STFI) will be presenting innovative highlights from research and development at Techtextil 2022, the international trade fair for technical textiles and nonwovens. In addition to a warp-knitted textile façade greening in a modular system and textile lightweight construction elements for the building sector made from hemp as a renewable raw material, the STFI will also be showing innovations from nonwovens research. The project optiformTEX is an example of the nonwovens competence: in this project, the mass per unit area was specifically influenced for the production of semi-finished products in the automotive sector. Furthermore, the Chemnitz Institute exhibits an ecological foam coating for protective textiles. Central highlight of the STFI's presence at the fair is also a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel.

Highlights at Techtextil 2022
The greened façade tile is a system with which large building surfaces can be cost-effectively greened through a simple, modular segment structure. In addition to insulating the building, the system has been created to meet the design requirements of a modern city centre; low-maintenance greening is made possible through functional integration in the textile carrier layer and coordinated plant selection.

Moulded components made of natural fibre nonwovens are increasingly used in the automotive sector. Conventional nonwovens currently have uniform masses per unit area. Technical solutions for load-oriented component reinforcement and the resulting optimised use of materials represent an enormous economic potential. The basic idea of “optiformTEX” was therefore to specifically influence the mass per unit area distribution in the pile before the semi-finished product is consolidated. As a result, a textile-technological process and the corresponding plant component were successfully developed.

Future-oriented materials are offered by developments from the field of renewable raw materials in combination with bio-based resin systems: In the “Gro-Coce” project, an innovative ceiling system was developed by combining sustainable building products and methods. Currently, a high-performance hemp-based semi-finished product as well as the steps for its reproducible production by means of textile surface formation is developed by the research team. Initial application and load tests of the hemp-based semi-finished products on wooden beams confirmed the high performance potential of the natural fibre materials.

Special functional textiles are based on composite materials with coatings or membranes. The previous production of the coatings/membranes poses ecological and health risks. At STFI, solvent-free, purely aqueous coating systems and a technology for their application were therefore developed for the protective textile sector, resulting in a breathable, waterproof and wash-resistant textile coating.

The central highlight of the STFI's presence at the fair is a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel. At the STFI, the robot is part of the “textile factory of the future”, where a play mat is woven and processed step by step along the textile chain.
