From the Sector

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.

Elastics for power support in medicine and the work environment
People who do physically hard work are relieved; people who are learning how to walk again after an accident or a stroke receive support; people with a handicap gain greater mobility – exoskeletons offer valuable support in many areas. An important component for "power suits": elastics by JUMBO-Textil.

Support construction with and without drive
An exoskeleton is a kind of robot that you wear: a construction of mainly textile components that is slipped over the body and strapped on. Integrated sensors register the body movements. These impulses are converted into electrically driven movements of the exoskeleton, which support or amplify the human movement. In addition, exoskeletons without drive are also being developed: these designs aim to transfer the weight of heavy tools or loads directly into the ground.

Tough requirements, individual solutions
Since the skeletons are worn on the body, the textiles and textile components used here need to be skin-friendly and as light as possible. The body's own temperature regulating systems must not be impeded. The contact surfaces must not create pressure points. And the exoskeletons must be individually adaptable to the user's body measurements.

High-tech elastics by JUMBO-Textil offer solutions for the development of exoskeletons – in terms of functionality, safety and wearing comfort: they hold, clamp, close and secure. They relieve and cushion movements and force impact. They illuminate and forward signals. The breathable narrow textiles stretch in both directions as required. They fit snugly on the body and follow every movement. Full-surface hook-and-loop-ready elastic tapes offer a simple, secure and individually adjustable fastening option. JUMBO-Textil consistently uses components made of plastic or light metal for textile components as fastening solutions. As a solution partner for demanding tasks – e.g., in occupational safety – JUMBO-Textil also developes cooled or heated textiles in collaboration with their customers. Also possible: the development of self-luminous narrow textiles – for additional safety.

This September’s Cinte Techtextil China will once again provide a strong barometer of the state of the global technical textiles industry, and in particular which sectors in Asia as a whole, and China specifically, are performing well. Two of these for certain are Buildtech and Mobiltech, with a number of leading global and Chinese brands exhibiting to eager buyers from these sectors.

Cinte Techtextil China is Asia’s leading biennial fair for the technical textiles and nonwovens sector, and will feature an expected 500-plus total exhibitors from around 20 countries & regions from 4 – 6 September. The fair offers products and technologies for 12 application areas* which cover the entire industry.

Buildtech benefits from Belt & Road and other infrastructure investment
