From the Sector

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.

From mechanical engineering to the construction industry, from logistics to rescue technology – tensioning and clamping systems fulfil important tasks in a number of industries. The possible uses of technical textiles for industrial applications of this kind are manifold.

Patented and precisely configured
The ElasTool system from the elastics expert consists of a connection tool and a rubber rope connected to this tool via integrated locking elements. The stainless steel, aluminium or plastic connection tool and the rubber rope – with a thickness of between 12 and 38 mm – are each configured to fit precisely. The highlight of the patented connection solution: the more tensile force is exerted, the more the rope is jammed. Thanks to the locking system, ElasTool still provides a secure hold even when the diameter of the rubber rope narrows to up to 60 percent due to the tensile load. A crucial advantage over conventional end connections by pressing.

Economical and low maintenance
The system has further advantages: the textile solution runs quietly. Unlike clamping systems with steel cable springs, there is no creaking here. In addition, textiles, plastic and aluminium are particularly lightweight materials. ElasTool therefore saves energy. Another benefit: the connection system works without lubricating oil. While conventional tensioning and clamping solutions in industrial plants and products have to be oiled regularly, the JUMBO textile system works completely maintenance-free.

Versatile and easily interchangeable
Depending on the area of application of the ElasTool, the interchangeable head can be exchanged: Plastic hook instead of aluminium eyelet, stainless steel flange instead of aluminium hook – for example. The interchangeable head can be replaced effortlessly and without special tools.

"A lifting system in a high-bay warehouse, a trolley in a crane, damping for compressors or crash systems – these are just three of the many possible applications. We adapt the dimensions, material, force-stretch behaviour, flame retardancy – like all properties – specifically to the respective project," emphasises Carl Mrusek, Chief Sales Officer of JUMBO-Textil. "Thus, with ElasTool, we offer a safe load connection for a wide variety of applications in industry."

Candour Techtex, a Melegaon JR Group company, is satisfied with the latest coating and lamination line supplied by UK’s Amba Projex and has ordered a second, wider one to meet increasing demand.

Based in High Peak near Manchester, BTMA member Amba Projex has over 40 years’ experience in the design and manufacture of special purpose technical textile machines, with coating and laminating installations around the world.

Amba will be working closely with Candour over the next five years, to establish an Indian technical textiles powerhouse capitalising on the UK technology provider’s long experience in the field.

Formerly Chandni Textiles Engineering Industries, Candour Techtex of the Malegaon JR Group assumed its new name in 2022 to reflect its focus on a wide range of technical textiles at its new plant in Malegaon in the Nashik District of Maharashtra.

The company was founded in 1986 and at its existing plant in Ankleshwar, Gujarat, produces an annual 1.2 million metres of light velvet fabrics mainly for the domestic market for apparel and light home furnishings. In 2020 it also began operations at a plastic moulded components division in Gonde, Nashik, with a capacity of 4,500 tons per annum.

Blackout fabrics
In particular, the new Amba Projex system enables blackout fabrics to be produced efficiently and at scale.

Blackout fabrics are installed in rooms where complete light shielding is required, such as in public institutions like hospitals, and retirement homes, in hotels and conference rooms, and also in the home, especially in bedrooms.

They obtain their light impermeability by a special three-layer blackout coating which works on textiles of all colours. Only the middle layer of the three coatings needs to be black for obtaining the necessary light absorption. The fabrics are usually also treated for permanent flame-retardancy, and also with water or stain-repellent finishes. In addition to locking out light and providing maximum privacy, blackout curtains also help to insulate a home and reduce energy costs, in addition to protecting furniture and carpets from fading due to sunlight exposure.

When the nonwoven industry meets at the leading trade fair INDEX in Geneva from 18 to 21 April, Mahlo GmbH + Co KG awaits trade visitors from all over the world to inform them about the right measurement technology enabling more efficient and high-quality production of nonwovens.

With a wide range of sensors, different measuring techniques and the corresponding measuring bridges, practically all tasks regarding the control of basis weight, moisture, thickness, fibre content, and air permeability can be solved in a cost-efficient and practical way.

As an example, Wulbeck mentions spunlace products. They mainly consist of fibres such as cotton, PE, PET or rayon. They absorb light in the near-infrared range. Water and all other materials have different spectral ranges and can thus be distinguished. The near-infrared sensor Infrascope NIR determines the moisture content and the basis weight of different materials by attenuating the light in certain wavelengths. Due to its very high spectral resolution, the sensor can distinguish between components with very similar but not identical IR absorption and achieves high measurement accuracy. "Up to 0.05 g/m2 of the respective coating weight is possible," says Wulbeck.

"We want to support manufacturers in optimising their production processes and thus also the end product," says Matthias Wulbeck, Mahlo product manager for QCS. Because, like many other industries, the nonwoven sector is struggling with challenges such as rising prices for energy and raw materials, long delivery times and uncertain supply chains. In order to continue to produce economically and on time, it is therefore necessary to save resources and avoid faulty production as well as unnecessary process times. "Our Qualiscan QMS measurement and control system helps to do just that."

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

A new cold chamber at its headquarters in Winterthur, Switzerland, enables Autoneum to optimize existing technologies as well as simulation and engineering services in vehicle thermal management and to adapt them to the changing thermal requirements of electric vehicles

The absence of heat from the internal combustion engine in electric vehicles as well as the impact of ambient temperature on the performance and lifetime of lithium-ion batteries are changing the requirements for vehicle thermal management. In addition, the energy from the battery is used not only to power the e-motor but also to thermally manage the battery itself and to warm and cool the car cabin by means of the heating, ventilation and air conditioning system. To increase the thermal comfort of the occupants and at the same time ensure optimum battery performance, save energy and thus increase the car’s range, manufacturers are placing increasing emphasis on efficient overall thermal management of the vehicle.

The chamber enables to test both occupants’ subjective perception of thermal comfort and the performance of components and entire vehicles under controlled temperature conditions of up to minus 20 degrees Celsius. It is thus a valuable addition to the existing testing and bench-marking facilities at the Company’s global research and development centers. The tests conducted in the chamber show how existing insulating components such as under battery shields, carpets and interior trim need to be optimized to further enhance the thermal management of the vehicle battery and cabin. The tests also provide valuable insights regarding the development and optimization of heated surfaces such as floor mats and door trim panels to improve thermal performance and driver comfort of electric vehicles.

Medline, a medical product distributor and manufacturer, together with Hologenix® launched a new line of CURAD® Performance Series® orthopedic products powered by CELLIANT® infrared technology.

CELLIANT, the flagship innovation of Hologenix, is a proprietary blend of natural minerals that allows textiles to convert body heat into infrared energy, returning it to the body and temporarily increasing local blood flow and cellular oxygenation. This has been clinically demonstrated to support recovery from physical activity and fatigue, increase endurance and stamina, and boost overall performance in healthy individuals, among other benefits.  

Trusted by athletes, CURAD is the Official Medical Supplier of the IRONMAN® U.S. Series. The new orthopedic products powered by CELLIANT infrared technology are the latest additions to the CURAD Performance Series collection and including different infrared supports designed for the ankle, knee, back, shoulder, as well as multipurpose use.

“This new CURAD Performance Series offering represents a major expansion of CELLIANT infrared (IR) bio-responsive textiles into the sports medicine field,” said Seth Casden, Hologenix Co-Founder and CEO. “We are honored to partner with Medline and look forward to future introductions.”

In addition to the inclusion of CELLIANT infrared technology, Medline has engineered the elastic supports to provide targeted compression for enhanced local circulation that helps reduce swelling, with a contoured fit that won’t slip or shift during normal activities with silicone grips that keep the product in place.

The removable hot/cold therapy supports provide adjustable compression and a gel compress that can be cooled or heated to further reduce swelling and discomfort.

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.
