From the Sector

100 days before ITMA 2023 in Milan, VDMA Textile Machinery launched its “Way2ITMA” webinar series. “Transforming the World of Textiles: efficient – digital – circular”. Under this heading, VDMA technology providers will present their solutions along the value chain.

Speakers of the virtual event were Dr. Janpeter Horn, Chairman of the VDMA Textile Machinery Association and Managing Director of August Herzog Maschinenfabrik, Dirk Vantyghem, Director General, EURATEX, Francis Elias Junker, Area Sales Manager, Andritz Laroche and Tanja Karila, Chief Marketing Officer, Infinited Fiber Company.

With regard to the EU strategy for sustainable and circular textiles, Dr. Horn said: “This topic concerns all of us, consumers and producers. We as machinery builders position ourselves as enablers. We want to be part of the solution of this ambitious project”.

Dirk Vantyghem introduced the core issues of the EU textile strategy launched in 2022, which is the most ambitious plan ever, to push the textile sector towards sustainability and transparency, and promote a new circular business model. If wrongly designed, that new framework may collapse the European textile value chain. But if done rightly, the changes ahead could bring a paradigm shift in the sector, where competitiveness is no longer based on price only, but also on sustainability and innovation, explained Vantyghem.

Francis Elias Junker showed high level of expertise for mechanical textile recycling for both spinning and nonwovens industries that Andritz has. The company has a diversity of solutions to offer and several cooperation partners, covering the value chain from recovery of fiber to the chemical modification and preparation for the production of yarn.

Tanja Karila gave an overview of how Infinited Fiber is turning textile waste into new fibers. Patented technology turns post-consumer textile waste into brand new premium quality fibers for the textile industry. The textile-to-textile recycling technology captures the value in waste that would otherwise be landfilled or burned.

Svegea of Sweden – a member of TMAS, the Swedish Textile Machinery Association – has recently installed an EC300-S collarette cutter for the high speed production of tubular apparel components as well as an FA350 automatic roll slitter at the plant of Löffler, in Ried im Innkreis, Austria.

The EC 300-S collarette cutter is equipped with the computer-controlled True-Drive II and high pre-feed device, which is used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements. It operates at speeds of up to 20,000 metres per hour. The integrated, fully automatic FA350 roll slitter FA500 roll slitter is equipped with three separately adjustable settings enabling three different band widths to be cut within the same cutting cycle. Automatic tube sewing units are provided for sewn tubes in optional rolled or flat folded forms, depending on customer preference.

Sports and knitwear specialist Löffler is celebrating its 50th anniversary in 2023. Its plant in Ried houses 25 circular knitting machines and three seamless knitting machines with an annual output of around 905,000 square metres of fabric, and in addition to product development, design, cutting and some sewing are all carried out in-house.

Löffler is known for its transtex under garments, which ushered in the two-layer principle of structures combining hydrophobic polypropylene and other fibres like cotton, Modal, Tencel or merino wool.

Before transtex, endurance athletes usually wore pure cotton underwear next to their skin, which became wet over time and cooled the body down. Löffler’s two-layer fabric prevented this, since the polypropylene does not absorb moisture and instead wicks it to the outside, where it can evaporate to keep the skin dry.

Innovation has been ongoing ever since, and in December, Löffler received an ISPO Award 2022 for transtex Retr’x – its latest functional underwear made from recycled polypropylene from textile waste and a combination of recycled and GOTS-certified organic cotton. Transtex Retr’x is neither dyed or bleached and is Standard 100 by Oeko-Tex as well as Made In Green by Oeko-Tex approved.

In addition to its own branded products, the plant makes sports garments for sister company Fischer, which is also based in Ried, and is at the same time involved in significant government tender projects, including the supply of polo shirts for the Austrian Red Cross and for the German and Austrian police forces. Combined, Löffler and Fischer employ approximately 700 people in the region of Upper Austria.

Gunnar Meyer has been assigned the new Managing Director of A. Monforts Textilmaschinen GmbH & Co. KG in Mönchengladbach, Germany, as of January 1st 2023.

He started his career with Monforts and has spent his whole working life in the textile machinery industry. Between 1985 and 2010 he was a key part of the Monforts team in various roles related to sales and commercial issues, including as General Sales Director. He returned to the company in 2019 after working for other well-known German textile machine manufacturers in the field of nonwovens.

“Working in other parts of the textile industry, I have gained a lot of experience in the management of complex technical textile projects and my special focus will certainly be on challenges like the current energy crisis, alternative heating systems and sustainable textile finishing,” stated Meyer.

Over the past year, TMAS, the Swedish Textile Machinery Association, has been working with ClimatePartner on a corporate carbon footprint (CCF) mapping project with its member companies, as a natural step towards supporting a more sustainable textile industry.

Over half of the members of TMAS are participating in the project, which involves calculating each operation’s Scope 1, 2 and 3 emissions in order to identify the current climate impact and areas where reductions can be made.

“Integrating climate action into strategies is becoming increasingly important in Europe and we have decided to take a pro-active role,” says TMAS secretary general Therese Premler-Andersson. “There is growing pressure from customers to be more transparant in this area and forthcoming legislation will soon make it necessary for all to take climate actions. TMAS members, however, recognise the benefit of taking action now, not least in terms of taking responsibility and demonstrating credibility.”

The CCF project’s scope examines all aspects of a business split into five areas:

• Facility Management (heating, electricity, water, cooling agents and waste disposal).
• Employee Mobility (commuting and company cars).
• Business Travel (flights travel by train, rental cars).
• Procurement (production, packaging and office materials).
• Logistics (inbound and outbound).

Primary data is being used wherever possible and emission factors originate from internationally recognised databases such as ecoinvent and GEMIS.

The ClimatePartner measurement programme is based on the guidelines of the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard (GHG Protocol), and factors in all greenhouse gases covered by the Kyoto Protocol. These are carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulphur hexafluoride (SF₆) and nitrogen trifluoride (NF₃).

Each of these gases affect the atmosphere differently and remain in the atmosphere for different lengths of time. Rather than reporting on each gas separately, they are expressed as a CO₂ equivalent (CO₂e) for the sake of simplicity. A CO₂e is essentially a conversion into a ‘global warming potential’ value that enables the influence of different gases on global warming to be compared.

ITM - International Textile Machinery Exhibition, which is one of the world's most important exhibitions in its field and carries its success beyond its borders, will be held in a country other than Turkey for the first time next year under the name 'ITM Uzbekistan'. 'ITM Uzbekistan 2023 Exhibition', which will be held in Uzbekistan New Expo Center on September 12-15, 2023, will bring together buyers from Central Asia and Turkic Republics with the world's most important textile and garment technology manufacturers.

ITM Uzbekistan to be organized in odd years
'ITM Uzbekistan', organised by Teknik Fairs Inc. and Tüyap Tüm Fuarcılık Yapım Inc., will be first held in September 2023, from 12th to 15th, and thenorganized in the following odd years such as 2025, 2027, and so on. The exhibition calendar was created by taking into account the dates of the exhibitions organized in the same sector in different countries of the world and in Europe and the benefits of the sector.

Tashkent New Expo Center
New Expo Center, built in Tashkent, the capital of Uzbekistan, will host the most important events of both Central Asia and Turkic Republics. New Expo Center, where many national and international events will be held, will be the gateway of Central Asia to the world. The exhibition center, consisting of a total area of 44 thousand square meters and two stages, was built with the latest technology, taking into account all needs. The new exhibition center, which includes cafes/restaurants, resting areas, meeting, congress, seminar and exhibition halls, is an important attraction center with its proximity to the new airport under construction in the capital and the facilities where the international Olympic Games will be held.

Monforts will be presenting its finishing technologies at the forthcoming Igatex textile machinery exhibition, which takes place from December 1-4 at the Lahore Expo Centre in Pakistan.

The importance of the textile industry to Pakistan’s economy cannot be overstated – it accounts for 60% of the country’s overall exports and some of its industry’s players are very major employers. In the year to June 2022, Pakistan’s textile exports climbed by 25% to a record value of $19.3 billion according to the country’s Bureau of Statistics, as security of deliveries – especially to Europe and the USA – worked in the country’s favour, in the light of the Covid-19 pandemic and subsequent supply chain issues. It has a key role to play in quickly getting the country back on its feet after the devastation.

Monforts customers in the regions around the country’s three biggest cities of Karachi, Lahore and Faisalbad include all of the main players in the fields of home textiles and denim production, including Afroze, , Al Karam Artistic Milliners, Azgard-9, Crestex, , Gul Ahmed, Interloop, Liberty Mills, Lucky Textile Mills, Mustaqim, Naveena (NDL), Rajby Industries, Sapphire Finishing, Soorty, Style Textile and US Denim.

These companies rely on established Monforts technologies including Montex stentering equipment, Monfortex sanforizing units and Thermex dyeing ranges. The company’s Matex Eco Applicator minimum application system has also proved a big hit in recent years.

Monforts has also achieved considerable success in Pakistan with its Econtrol®* dyeing system  – an effective and established dyeing process. More than 40 Thermex continuous dyeing ranges have been installed in Pakistan in recent years and operator training on the Econtrol®* process by sophisticated technologists is an additional service.

The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step. Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

An immediate wash off is also unnecessary, allowing for flexible production planning. The process is suitable for pale to dark shades with very good fastness properties. Also waste water treatment is improved by this technology.

*Econtrol is a registered mark of Dystar Colours Distribution GmbH.

BTMA member Sellers Textile Engineers is marking its 110th anniversary this year with the introduction of a new concept in carpet shearing, as the essential final step in ensuring tuft uniformity and ‘just new’ freshness in finished carpet rolls.

The company has for many years offered two options in the construction of its shearing cylinders – the first, namely the ‘strap-on’, incorporates spiral blades bolted to the cylinder body and the second, known as the ‘caulked-in’, includes spirals which are fixed very securely in a machined groove within the machine.

The new Sellers’ Hybrid Shearing Cylinder combines the benefits of both, resulting in an improved cut and finer finish, in addition to longer repeatable finishing and increased rigidity.

“The Hybrid Shearing Cylinder has all the advantages of the ‘strap-on’ spiral blade to provide a sharper and cleaner cut, along with enhanced rigidity which significantly lengthens the intervals between the necessary regrinding of the blade,” explains Sellers Director Neil Miller. “We currently have six Hybrid Shearing Cylinders operating in the field and the earliest, which has been installed in both No1 Head position, where the majority of the shearing operation and heaviest cut is performed, and also in No3 Head, where the sharper cutting angle has resulted in a much improved surface quality.”

Sellers shearing machines have led the field in carpet finishing for many decades, enabling the leading manufacturers to stay competitive by enabling the highest quality of finish to be achieved economically and efficiently.

The latest advanced features of these machines include a load cell tension control drive system, an automated touchscreen for easy operator control and fault diagnosis, an enhanced cleaning system including cylinder and blade separation and fully controllable pivoting beds. Further options include thickness monitoring, seam detection and metal detection systems.

“The Hybrid Shearing Cylinder will become standard on our latest machines and also be made available for retrofitting, to provide significant benefits to our existing users,” says Miller. “All of our equipment is designed, manufactured, assembled and tested at our plant in the UK, and as one of the few remaining European engineering companies to make all of our components in-house – with now over a century of accumulated know-how – flexibility in design allows our finishing solutions to be targeted to specific customers and their product requirements. Aligned to this is a lead in process control systems which ensure the accurate control, reliability and repeatability of the processing parameters on all of our machines.”

Sellers remains committed to providing complete finishing solutions for all carpet, tile and artificial grass products. Its range includes machines for tufted secondary backing, both conventional, powder and extrusion lamination, Wilton and Axminster products, artificial grass and foam lines, coating lines for bitumen, PVC, PU and other polymers, as well as shearing for all carpet products.

Ongoing developments on the company’s coating and drying lines have resulted in improved guiding and product tension control as well as dryer efficiency, reducing heat loss and optimising energy use. These include a re-design of the fan pressure boxes and impingement nozzles to increase airflow efficiency, modulating gas burners and introducing easy clean, accessible filters.

In addition, the proven dual zone system has been enhanced, giving a temperature differential of up to 80°C between top and bottom zones. Dryers can be heated by either gas or steam and operation and access have been simplified with controls via touchscreen and PLC.

An extensive range of ancillary equipment is available to provide maximum flexibility to cover product requirements, for both new processing lines and as upgrades to existing equipment.

“Carpet manufacturing is now based on well-established, tried and trusted processes and it’s rare for new innovations to be introduced into this sector,” says Jason Kent, CEO of the British Textile Machinery Association. “The new Sellers Hybrid Shearing Cylinder can provide a competitive edge for manufacturers which is currently being proven in the field. It’s one of a number of new innovations the company is planning to showcase at next year’s ITMA exhibition in Milan.”

Leading computerized knitting machine manufacturer SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its Turkish sales representative TETAS A.S., will participate in the CAITME 2022 Central Asian International Textile Machinery Exhibition in Tashkent, Uzbekistan next month.

This is the first time SHIMA SEIKI products are shown at the exhibition. Uzbekistan has been keen to convert its industry from raw material supplier to garment exporter, and therefore its market offers new opportunities for development and implementation of new technology.

To that end, SHIMA SEIKI will exhibit its WHOLEGARMENT® knitting technology that can knit an entire garment and requires no post-process sewing. On display will be the MACH2VS WHOLEGARMENT® knitting machine. The flexible and versatile MACH2VS is capable of knitting a range of production styles. As a conventional shaping machine, it is capable of all-needle knitting in its available range of 8 to 18 gauge, while WHOLEGARMENT® knitwear can be produced in half-gauge fabrics. The range of usable yarn and material has increased as well, thanks to i-DSCS＋DTC® as standard equipment. The R2CARRIAGE® system that yields quicker carriage returns for greater efficiency, now features a lighter carriage for even higher productivity. MACH2VS is even capable of gaugeless knitting whereby a number of different gauges can be knit into a single garment.

Meanwhile the N.SSR112 computerized flat knitting machine offers leading technology in an economical yet reliable package. Featuring industry-leading innovations such as the R2CARRIAGE®, spring-type moveable sinker, DSCS® Digital Stitch Control System, stitch presser and takedown comb, Made-in-Japan quality, reliability, productivity, user-friendliness and cost-performance combine to satisfy the high expectations of the world's fashion industry.

Demonstrations will be performed on SHIMA SEIKI's SDS®-ONE APEX4 design system. At the core of the company’s "Total Fashion System" concept, SDS®-ONE APEX4 provides comprehensive support throughout the production supply chain, integrating production into one smooth and efficient workflow from yarn development, product planning and design, to production and even sales promotion. Especially effective is the way SDS®-ONE APEX4 improves on the design evaluation process with its ultra-realistic simulation capability, whereby virtual samples replace physical sampling, consequently reducing time, cost and material that otherwise go to waste. Digital prototyping using virtual samples on SDS®-ONE APEX4 help to digitally transform the fashion supply chain for realizing sustainable manufacturing

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.

The recent Techtextil show in Frankfurt emphasised the diversity of applications for nonwovens and technical textiles, according to finishing technology specialist Monforts.

“We fielded enquiries at top management level from an extremely wide range of companies, all with very different ideas for new product applications during the show,” said Alexander Fitz, who joined the company a year ago as engineer for textile technologies and co-ordinator of the Monforts Advanced Technology Centre (ATC). Fitz brings a background in both technical textile technology and processes to the role, having previously worked for a nonwovens machinery builder and a roll-goods manufacturer.

Trials
“We are now looking forward to interesting new trials and pilot production runs, as well as the commissioning of new orders for machines resulting from the extremely busy exhibition,” he says. “Obviously, everyone at the moment is looking to make energy savings, and we have developed a range of options for helping companies increase their resource efficiency, both on new lines and as retrofitted systems, but this is not stifling innovation at the new material level.

“There was a lot of interest in what is possible with the Montex®Coat coating system and the range of different techniques it enables, and at our ATC in Mönchengladbach, a Montex®Coat unit is integrated into the full technical textiles pilot line, on which it is possible to run new fabrics in widths of up to 1.8 metres.”

Explosion proof
The technical textiles line at the ATC incorporates a Montex four-chamber stenter and is fitted with an explosion-proof coating application chamber in order to allow treatment to be carried out with organic solvents and other volatile materials.

Every single component within the chamber has to meet the standards of the European Union’s ATEX directives for working in a potentially explosive atmosphere. A range of sensors linked to alarms operate at various levels within the chamber to ensure the specified lower explosion limit (LOL) is never exceeded and the ventilation adapts accordingly.

Advanced functions
Special features on the finishing line relate to further advanced functions such as the ability to treat materials not only at temperatures of up to 320°C, but also to be able to treat the top and bottom faces of certain materials at different temperatures within a single pass through the machine.

To achieve this, the first two chambers of the stenter are fitted with special, heavy duty TwinAir ventilation motors and separate burners for individual top/bottom temperature. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment paramenters.

Another key feature of the technical textiles line at the ATC is the special stretching device which is capable of pulling ten tons in length and ten tons in width – a huge amount per square metre of fabric and necessary in the production of materials such as woven or 3D knits for high temperature filter media.
