From the Sector

International technology group ANDRITZ will be presenting its nonwovens production solutions at CINTE 2022 in Shanghai, China – one of the main trade fairs for technical textile and nonwoven products in Asia. ANDRITZ will show its product portfolio covering 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.

ANDRITZ supports nonwovens producers in the move to sustainability with the aim of reducing or eliminating plastic components while maintaining the high quality of the desired product properties. This applies to all types of sustainable wipes, such as flushable, biodegradable, bio-sourced, carded pulp or standard carded wipes. The latest development in this field is the ANDRITZ neXline wetlace CP line, which integrates the carded-pulp (CP) process. This is a fully engineered production line combining the benefits of drylaid and wetlaid technologies to produce a new generation of biodegradable wipes.

The neXline wetlaid aXcess targets smaller and medium production volumes and has been devised for new and existing lines. The line is easy and fast to ship due to the compact design, which also fits perfectly into containers. An operator-friendly configuration and versatile design ensure efficient production at affordable investment costs.

The aXcess range was specially developed at ANDRITZ (China) Ltd. Wuxi Branch to handle medium capacities. The facility in Wuxi has an experienced platform for production and service specially geared to serve the Asian nonwovens industry. With the aXcess range, ANDRITZ has developed a hybrid line combining European and Chinese machines, which is the ideal combination to obtain the best added value from each component in the line and be very flexible to accommodate different business cases.

After three years, VUB a.s again got the chance to actively participate in the European trade fair Techtextil 2022m being present at a joint stand of Czech companies active in production and application of technical textiles, organized by Clutex - Cluster Technical Textiles.

In cooperation with partners from academic and production sphere many products were developed over the past years, sold by VUB under the brand Clevertex. For the presentation at the fair, a wide range of ESD protective clothing for the electrotechnical industry and for each worker dealing with electrostatic discharge sensitive components was on display. As well as another product line of the Clevertex brand representing wearable skincare textile products with antiseptic effects based on purely natural textile materials.

Attention was paid to the advanced solutions for smart textiles and e-textiles products esp. electrically conductive hybrid threads based on ultrafine metallic micro-wires. A significant advantage of these threads lies in their full compatibility with standard textile manufacturing processes, and possibility of customization in terms of fineness, electrical conductivity and temperature resistance of individual thread. As an example of one of the applications of conductive threads, different types of woven elastic conductive ribbons were demonstrated, which could be used as bus bars or as textile conductors wherever a variable length of conductive element is required without the negative influence on their electrical resistance during the change the length.

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.

More than 450 participants from 18 countries made in-person connections and gained innovative insights into the segment’s future at the World of Wipes® (WOW) International Conference at the Marriott Marquis in Chicago.

INDA, the Association of the Nonwoven Fabrics Industry, reported strong attendance and activity at its 16th WOW conference, June 27-30. Highlights included a conference, award presentations, a separate 1.5-day WIPES Academy training course, and a new mentorship program.  

WOW speakers focused on the future of the $17 billion wipes sector amid changing consumer trends, supply chain complexities, sustainable packaging demands, and medical disinfection challenges. Program sessions included Circular and Sustainable Wipes, Supply Chain Challenges, Sustainable Substrates, Disinfection Concerns, Sustainable Packaging Trends, and Flushability Developments.

Tony Fragnito welcomed participants in his new role as INDA President for the first time since succeeding Dave Rousse, now President Emeritus and advisor.

WOW highlights included the announcement of Nice’ N CLEAN® SecureFLUSH™ Technology Flushable Wipes from Nice-Pak as the winner of this year’s World of Wipes Innovation Award® for their flushable wipes made of 100 percent cellulose nonwoven. A specialty “lock and key” design of plant-based fibers and formula leverages patent-pending technology to ensure responsible care of plumbing and wastewater.

Other highlights included the presentation of the 2022 INDA Lifetime Technical Award to Richard Knowlson, Principal, RPK Consulting. The award honors an individual with a long-established nonwovens career that advance technology and the commercial success of the North American nonwovens industry. Knowlson pioneered the use of powder super absorbents in airlaid forming systems creating new period product designs for ultra-thin products. He co-founded Airformed Composites, co-invented the first commercial multi-bonded airlaid products in North America that were used in characters for Sesame Street and served in leadership positions with Rayonier, Ciba/Huntsman and Jacob Holm.

The 2002 prize of the Walter Reiners Foundation of the VDMA Textile Machinery Association for the best Master's thesis in German textile mechanical engineering was awarded to a young engineer from the ITA Institut für Textiltechnik of RWTH Aachen University. The prize ceremony took place at Techtextil 2022 in Frankfurt am Main, Germany. Peter D. Dornier, Chairman of the Board of the Walter Reiners Foundation, presented the award at the VDMA Textile Machinery Association’s booth.

Felix Xaver Zerbes, M.Sc., was awarded the "Promotional Prize for the Best Master's Thesis of the German Textile Machinery Industry 2022", endowed with 3,500 EUR, for his master's thesis "Development and Construction of a Separation Unit for Weft Yarns in Air Jet Weaving".

The subject of the master's thesis was the development of a mechanism with which faulty sections in the weft yarn can be sorted out before they are woven into the textile. This way, both yarn-related weft defects and material defects can be drastically reduced. The prototype developed by Mr Zerbes shows how this can be done even during the ongoing weaving process without having to stop production. Due to its modular design, the yarn rejection unit can be retrofitted to many different types of air-jet weaving machines, which represents an enormous savings potential not only in Germany but in weaving mills all over the world.

• Biotransformation technology for nonwovens

Avgol^® has received the prestigious Innovation Award at the RIGHT Hygiene conference in recognition of its collaboration with Polymateria in development of pioneering biotransformation technology for nonwovens.
 
Biotransformation is a unique functionality wherein a conventional nonwoven fabric can be modified to react to certain triggers to then begin a cascade, and importantly a fundamental chemical transformation of the polymer resin into a wax that is readily degraded by natural bacteria, microbes and fungi normally found in the environment.
 
“The transformation is triggered through the combined effects of the natural elements of decay - air, moisture, heat and sunlight,” said Mr. Sanjay Bhayani, Director of India Operations with Avgol. “Once triggered, the material will transform into a low molecular weight wax structure leaving no microplastics or toxic residue behind. Moreover, if the product comprising the biotransformation technology is disposed of in the normal way and facilities are available, then it can be recycled by readily available means.”

“By bringing the Biotransformation technology to the various potential markets in India, we hope to offer a real-world solution to waste management,” he said. “We particularly hope to address aspects of the creation of fugitive waste and remove this from the environment without causing additional, and potentially more dangerous, problems.”

INDA, the Association of the Nonwoven Fabrics Industry, has announced the nomination process is now open for the annual RISE® Innovation Award. The prestigious award will be presented at the RISE® (Research, Innovation & Science for Engineered Fabrics) Conference – September 27-28, 2022, at North Carolina State University, Raleigh, NC.  RISE^® 2022 is a two-day conference presenting insightful research and science that propels product development.
