• Focus on straightening technology and process control

At Indo Intertex, held from 10 to 13 August in Jakarta, visitors get to see the Mahlo-way for process control in textile production. The German machine manufacturer and its partner agency Agansa Primatama will be available to show everyone its leading straightening technology as well as energy saving concepts around the stenter frames. INDO INTERTEX is South East Asia’s largest trade show on the textile and garment industries, bringing together leaders to experience world-class manufacture, technology and solutions.

Indonesia is one of the ten biggest textile producers in the world. Especially the USA, the European Union and Japan import a majority of their requirements from the Southeast Asian Island state. In order to fulfill the increasing demands and the call for high quality goods, producers invest in machinery, equipment and technology.

At IndoIntertex, Mahlo informs about its straightening machine Orthopac RVMC-15, among other. Based on experience reaching back to over 75 years, the machine offers the latest technology for correcting distortions. The modular straightening and process control system ensures a straight-thread product before and after the drying or fixing process and optimises the processes all around the stenter. This increases quality and saves resources and energy. The process control system Optipac VMC-15 measures and controls critical parameters such as dwell time, thread density or residual moisture.

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.

In light of the current pandemic circumstances in China, the 2022 edition of Intertextile Shanghai Home Textiles Autumn will be deferred. The Autumn fair, which was originally scheduled to be held from 15 – 17 August at the National Exhibition and Convention Center in Shanghai, will now take place in 2023 at the same venue. The fair’s organisers will announce the new date in due course.

Ms Wendy Wen, Senior General Manager of Messe Frankfurt (HK) Ltd, explained the decision: “After holding discussions with our stakeholders, we have made what we believe to be the responsible decision to delay the fair. While the call was made with the safety of the fair’s participants in mind, deferring the fair to the early part of next year will also allow more time for fairgoers to plan for their participation.”

“We understand that there is a lot of anticipation surrounding this fair, with exhibitors and buyers eager to connect in person. We would like to thank all participants for their patience and understanding, and also to express our continued dedication to provide a quality international trading platform for the home textile industry.”

Exhibitors or visitors with any further enquiries related to the fair can email, or visit the fair’s official website.

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.

A delegation from TMAS, the Swedish textile machinery association, will participate in the forthcoming Febratex textile show which is being held in the German Village Park in Blumenau, in Santa Catarina, Brazil from August 23-26.

As the fourth largest textiles manufacturer in the world, Brazil’s annual revenues from textiles and apparel amount to an annual $48 billion and the industry employs around 1.5 million people directly.

As with the USA and many European countries, product shortages resulting directly from the Covid-19 pandemic, and subsequent supply chain difficulties, have emphasised to Brazil’s industry the attractiveness of more diversified and shorter supply chains which are closer to customers wherever possible. In the past two years, there has been less reliance on imports from Asia to Brazil, and opportunities are arising again for local manufacturing.

Svegea of Sweden has supplied many automatic collarette cutters to Brazilian companies, which are used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements.

Svegea supplies many other bespoke machines for applications in the production of both garment components and technical textiles, including rewinding, measuring, inspection and band knife machines.

Eton Systems, the inventor and world’s leading provider of automated production systems for apparel and other textile-based processes, has supplied a large amount of workstations to Brazilian companies over the years, and believes its newly-launched Opta system is good news for this market becoming more efficient and profitable.

Automation is also high on the agenda of ACG Kinna Automatic, which specialises in automation solutions for filled products such as quilts, pillows and mattresses and also has extensive knowledge in areas such as bed linen and textile filters.

Given Brazil’s extensive forestry sector, the country is a key market for Texo AB, one of the world’s leading manufacturers of weaving machines for the production of paper machine clothing (PMC).

All paper manufacturing machines require a regular supply of PMC, which as large continuous engineered fabrics, carry the paper stock through each stage of the paper production process. With technologically sophisticated designs, they employ fibres and other polymeric materials in complex structures and each paper machine has an average of ten separate fabrics installed on it. Although the PMC business represents just a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates.

ROICA™ strengthens its presence in the apparel segment thanks to its established network of partners, who will present their latest innovations at the upcoming Première Vision.

ROICA™ partners are the “artists” and “heartists” of premium stretch in fabrics: because they have at heart all the values for which ROICA™ stands for. These partners presenting at Première Vision are:

• Iluna Group, whose journey into the new dimension of responsibility continues with developments in GRS (Global Recycled Standard) certified recycled yarns aimed at unprecedented effects in looks, performance and hands. Brand new for this edition of Première Vision is the inclusion of GOTS-certified organic cotton in GRS-certified galloons and allover lace containing ROICA™ EF, so as to meet market demands for natural comfort in the underwear sphere.
• Innova Fabrics, which recently enhanced its smart offering by launching the RF (Residual Free) line, with the goal of reducing the impact of microplastics derived from the fashion industry. This is made possible by mixing two responsible ingredients, SENSIL® BioCare by Nilit and ROICA™ V550 by Asahi Kasei, which give birth to both sporty and casual fabrics.
• Inplet, which enriched its production of smart elastic and rigid knitted fabrics with three new products: a powernet fabric in 77% polyamide RECO and 23% ROICA™ EF with good recovery; a net fabric in 55% polyamide RECO and 45% ROICA™ EF characterized by a soft hand and good elasticity; and a 79% polyamide and 21% ROICA™ V550 good power, good recovery and a soft touch.

• Tessitura Colombo Antonio, which in its new A/W 23-24 collection expands its proposal of regenerated lace from the ECO-LACE line: new designs inspired by fashion trends using ROICA™ EF. Also, in its BIODEGRADABLE line it uses ROICA™ V550 for the realization of new designs. The new MICROMODAL line uses ROICA™ V550; the effect of this lace range is softness, elegance and relief effect.

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.

Die Verleihung der Förderpreise 2022 der Walter Reiners-Stiftung des VDMA, Fachverband Textilmaschinen an Studierende und Nachwuchsingenieur:innen deutscher Universitäten für Spitzenleistungen im Studium fand am 22.

Die grundlegenden Erkenntnisse zeigen dabei das Potenzial daraus hergestellter faserbasierter Filter zur deutlichen und nachhaltigen Minimierung der MNP-Belastung, sowohl von lokalen Trinkwasserquellen bis hin zu globalen Wasserkreisläufen, auf. Die Masterarbeit beinhaltet erstmals die innovative Anwendung von Cyclodextrinmolekülen zur Anbindung kleinster Plastikpartikel unterschiedlicher Form und molekularer Zusammensetzung.
 
Simon Hoebel erhielt den mit 3.000 EUR dotierten Nachhaltigkeitspreis „Beste Forschungsarbeit des Deutschen Textilmaschinenbaues 2022“ über die „Weiterentwicklung des Versuchstandes zur Herstellung von flexiblen hochdrapierbaren Thermoplastfaserbandstrukturen aus recycelten Carbonfasern und Thermoplastfasern für hochbelastbare thermoplastische Verbundbauteile“.
 
Das Ziel der prämierten Forschungsarbeit bestand in der Weiterentwicklung eines Versuchstandes sowie eines anwendungsbezogenen technologischen Knowhows zur Entwicklung und Fertigung von unidirektionalen hochdrapierbaren Thermoplastfaserbandstrukturen aus recycelten Carbonfasern (rCF) und Thermoplastfasern (TFS) für hochbelastbare thermoplastische CFK-Bauteile. Im Rahmen der Forschungsarbeit untersuchte Hoebel den gesamten Prozess zur Herstellung von hochdrapierbaren Thermoplastfaserbandstrukturen von der Kardierung, Verstreckung, Banddoublierung und Konsolidierung. Aus den entwickelten rCF-TFS wurden thermoplastische UD-Verbunde gefertigt und ihre mechanischen Eigenschaften charakterisiert. Die Ergebnisse der Studienarbeit zeigen das Potenzial dieser neuartigen Prozesskette und der darauf basierenden leistungsfähigen und nachhaltigen Thermoplastfaserbandstrukturen auf Basis von rCF.

The viscose specialities manufacturer Kelheim Fibres has won the Techtextil Award in the "New Concept" category for their project "Cellulose-based nonwovens for highly absorbent reusable products".
This award is intended to make cutting-edge developments visible, promote unconventional thinking and intensify the dialogue between researchers, manufacturers.

The starting point for the innovation was the search for a washable and thus reusable absorbent pad made of completely bio-based materials for the cloth diaper of the Berlin-based start-up Sumo.
Two main requirements of the application are obvious: A fast and efficient liquid distribution and high absorbency should minimise rewetting and leakage. Both are ensured by speciality viscose fibres from Kelheim, which have been making this essential contribution to absorbent hygiene products such as tampons for many years. The obvious solution was therefore to optimally utilise the synergies between knitted and woven structures with nonwovens.

In doing so, the advantages of nonwovens in combination with speciality viscose fibres in terms of absorbency (through e.g. more open-pored structures) have been perfectly transferred from the field of disposable to the world of reusable products. For reusable products, however, there is another challenge to overcome: they must remain stable during washing and over several cycles of use. To ensure this, an innovative nonwoven construction was developed in close cooperation with the STFI. These nonwovens can be used as a stand-alone solution or integrated into a textile structure.

• Target markets: automotive, furnishings, sports and technical apparel
• New product entry: radipeople® line of personal protective equipment

RadiciGroup is at Techtextil 2022, the leading European trade fair for technical textiles, taking place in Frankfurt am Main, Germany, from 21 to 24 June. On display in the RadiciGroup exhibition area are the Group’s latest products for the automotive, furnishings and apparel markets: from nylon and polyester yarn, including biosource and recycled lines, to nonwovens and the new radipeople® line of personal protective equipment (PPE).

Indeed, at Techtextil, RadiciGroup is showcasing RENYCLE®, a yarn obtained from recycled nylon; REPETABLE®, a polyester yarn from post-consumer recycled plastic bottles; RESPUNSIBLE®, a nonwoven fabric from recycled polypropylene; and BIOFEEL®, a brand identifying a yarn line obtained from renewable sources of both nylon and polyester.

Moreover, RadiciGroup is participating in a forum organized by the Technical Textiles Section of Sistema Moda Italia in collaboration with the Italian Space Agency (ICE) (Hall 12.1 – Stand C58), with the goal of introducing product innovations not only coming from a single manufacturer, but also from an innovative synergistic approach all along the supply chain, from raw materials to finished products. An example of this synergistic collaboration is the “Mars Spacesuit”, recently tested in the USA by analogue astronauts as part of a space medicine project designed to measure the vital signs of future astronauts and develop technologies to support the simulation of life in space and planetary environments. RadiciGroup teamed up with major Italian textile companies and supplied the materials to make the suits for the six analogue astronauts participating in the mission and coordinated the development of the technologies needed to create the technicalwear for use in extreme environmental conditions.
