From the Sector

Monforts, which is celebrating its 140th anniversary this year, will exhibit a Montex stenter chamber with an integrated overhead heat recovery unit at the forthcoming ITM textile machinery exhibition in Istanbul from June 4-8.

The heat recovery unit on display at the stand of Monforts partner Neotek is just one of a range of energy saving options the company is now providing for both new and existing line installations.

Monforts Montex stenters and Thermex dyeing ranges are industry standard for the fabric finishing industry, providing many advantages in terms of production throughput and especially in energy efficiency and savings.

coaTTex
At ITM, Monforts will also introduce its latest coaTTex coating unit, dedicated to air knife and knife-over-roller coating. For single-sided application with paste or foam, the versatile coaTTex is suitable for both incorporation into existing finishing ranges as well as installation with new Monforts lines, especially Montex stenter systems.

A wide range of coatings can be applied to fabrics for providing functions such as waterproofing, liquid and gas protection and breathability, in addition to foam lamination and coating, including black-out coating.

Central location
“In Turkey we are very strongly supported by our representative Neotek, our solution partner on the ground for service, installation and commissioning, providing specialised and rapid help to all of our customers,” says Monforts Area Sales Manager Thomas Paeffgen. “ITM is always one of the most important exhibitions for Monforts, for meeting customers not just from Turkey, but across the Middle East and Central Asia, as well as Bangladesh, India and Pakistan.

“Istanbul’s centralised position makes it accessible to the majority of the major textile manufacturing hubs and as we mark our 140th anniversary in 2024, having been founded back in 1884, the ITM show will provide us with the ideal opportunity to celebrate with colleagues and customers all together in one location.”

Together with the German circular knitting machine builder Mayer & Cie., Groz-Beckert has developed the optimized Relanit sinker SNK F over the past years. Independently of this, the development of the new LCmax™ energy-saving needles took place. The focus of both developments is on efficiency, energy savings and increased process reliability.

Groz-Beckert offers interested machine builders different cooperation options to jointly develop new products or optimize existing ones. The Groz-Beckert Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects. At the ITMA in Milan in June 2023, Groz-Beckert presented some of the successful cooperations under the motto "Innovation through cooperation". Among them were two new developments realized with Mayer & Cie. Groz-Beckert presented the two new products for the first time in Asia at ITMA Asia in November 2023.

Optimized Relanit sinker SNK F
At the end of 2018, circular knitting machine manufacturer Mayer & Cie. approached Groz-Beckert with a request to jointly develop an improved and more efficient sinker for selected machines of their Relanit family that would run more smoothly and reliably in the needle tricks. The innovative sinker has an integral spring with a spring force that is adapted to the sinker thickness. Field tests were consistently successful and confirmed the functionality and advantages of the new sinker.

Thanks to their adapted spring, the newly developed SNK F Relanit sinkers are securely guided while they are running through the cam track, resulting in a quieter operation. This increases process reliability and ensures an improved loop structure. In addition, wear on the swivel butts of the sinkers is reduced. This increases service life and makes the process more sustainable and cost-efficient.

Higher energy efficiency thanks to LCmax™
The objective second recent cooperation with Mayer & Cie. was to develop a cost-effective energy-saving needle. After considering various variants, the common choice of Mayer & Cie. and Groz-Beckert was the LCmax™ knitting machine needle with innovative, wave-shaped shank geometry. The first prototypes were extensively tested on laboratory machines at Groz-Beckert's TEZ.

The wave-shaped shank of the LCmax™ needle ensures a smaller contact area of the needle in the needle trick. This results in less friction, which reduces machine temperature and enables energy savings of up to 20 percent compared to a standard needle. This saves costs and at the same time allows operation of the machine at the maximum possible speed.

In both projects, the cooperation between Mayer & Cie. and Groz-Beckert went far beyond mere product development. In addition to Applications Engineering and Construction, the companies' Sales and Purchasing departments were also involved in a close exchange.

BTMA member Tatham has just delivered an advanced industrial hemp processing line to a major customer in Turkey and had many fruitful discussions about its machinery for the processing of natural staple fibres at the recent ITMA 2023 held in Milan from June 8-14.

The Bradford, UK-based company continues to equip mills around the world with staple fibre spinning and nonwoven technologies for manufacturing a wide range of products, while its TS system for drives and controls is suitable for retrofitting to all OEM textile machines, to provide user-friendly control systems with complete synchronisation and significant energy savings.

“We are currently fielding a lot of enquiries for technologies for the decortication, fibre opening and fabric forming of hemp,” said Tatham director Tim Porritt. “This is being driven by the sustainability of the fibre and concerns over climate change as brands seek solutions to meet their sustainability goals. As a result, there has been an explosion in the interest in hemp production, from farmers through to fibre production, and a wide range of new potential end-uses are being explored.”

Tatham offers a complete ‘Field to Fibre’ service for industrial hemp fibre production and its decortication and cleaning process has a gentle opening action to maintain the fibre length, to make it suitable for subsequent processing.

Groz-Beckert will be represented at ITMA with its six product sectors and will showcase its various innovations. The presentations at the booth will be supported by augmented reality applications. This allows visitors to discover the products both live and virtually.

The Knitting product sector will be represented at the Groz-Beckert stand with its four product groups circular knitting, flat knitting, legwear and warp knitting. In the circular knitting segment, for example, two newly developed knitting systems will be on show which have been realized in collaboration with machine manufacturers. The developments focus on energy savings, extended cleaning intervals and increased process reliability.

In addition to the machines for weaving preparation, the Weaving product sector will present its recently expanded portfolio of technical weaving reeds. The new weaving reeds make it possible to supply customers who produce fabrics with high densities. The weaving reeds are used in the production of special fabrics, for example, in technical filtration, membrane technology, solar cells or touch screens.

Products and services for classic needling and hydroentanglement will be presented by the Felting (Nonwovens) product area. In the field of felting needles, visitors can look forward to two innovations: a new notch shape and the Groz-Beckert felting needle module. In the felting needle module, the needles are embedded as a module in a plastic mold for the first time. The needle modules are characterized by high deformation resistance and offer new dimensions in needle density.

For the production of tufted floor coverings such as carpets, bath mats or artificial turf, the Tufting product sector will be presenting its proven Gauge Part system.

Various new and further developments will also be shown by the Carding product area. For those interested in the nonwovens industry, for example, the world's finest Interlocking wire for reduced risk of crashis included. For customers of the spinning industry, the division will be presenting further developed stationary flats and revolving tops. The new revolving tops have been adapted to the processing of fine yarns, while the stationary flats have been provided with a new, resistant aluminum profile.

The Sewing product sector is focusing on the presentation of its special application needles, SANTM. The sewing machine needles of the SANTM series have been specially developed for demanding sewing operations – e.g. for sewing technical or finest textiles. The division will also be presenting its new Needle Finder. The Needle Finder is an interactive tool in the online customer portal that helps customers select the right needle.

Alchemie Technology is the latest company to join the British Textile Machinery Association (BTMA), as all of the organisation’s members gear up to showcase an array of new innovations at ITMA 2023 in Milan from June 8-14 this year.

Cambridge-headquartered Alchemie is the inventor of two technologies – EndeavourTM and NovaraTM.

The Endeavour digital dyeing system produces no wastewater and reduces water consumption by up to 95% compared to traditional dyeing. The virtually waterless process delivers dyed fabric with high colour consistency and colour fastness and does not require post dyeing washing steps which leads to an energy reduction up to 85%. It can deliver any colour shade required and enables on-demand digital colour changeovers in any run length, from a few metres to several kilometres.

Similar energy savings can be achieved with the Novara precision finishing system which utilises a nozzle array to deliver finishing chemistry with millimetre resolution. Finishing chemistries penetrate deeply into the fabric due to the combination of high velocity liquid jetting and precisely-controlled vacuum and textile finishes are applied only where needed, reducing chemistry usage and enabling multi-functionality.

In the past year, Alchemie, backed by Swedish fashion giant H&M, has established a first demonstration hub at customer JSRTEX in Taiwan. It is now progressing plans to set up further centres at customer sites around the world.

• Annual assembly of ACIMIT, the Association of Italian Textile Machinery Manufacturers

• Digitalization and Sustainability Key to Resiliency for Italian Textile Machinery Sector

The objective critical issues faced by Italy as a whole throughout the course of 2021, primarily dictated by a pandemic that upset any and all pre-existing equilibriums, have not slowed or halted the Italian textile machinery sector.

Indeed, data presented during the annual assembly of ACIMIT, the Association of Italian Textile Machinery Manufacturers, held on 1 July proved decidedly positive, showing that in 2021 the sector recovered significantly compared to 2020, to the point of returning to pre-Covid levels.

Specifically, Italian textile machinery production amounted to 2.388 billion euros (+35% over 2020 and + 5% over 2019), with total exports amounting to 2.031 billion euros (+37% over 2020 and +9% over 2019).

However, these results do not cancel the obstacles that companies are still facing. Looking to the near future, expectations are for a rather uncertain outlook, as underscored by ACIMIT President Alessandro Zucchi: “2022 remains a year replete with unknown factors, starting with the Russian-Ukrainian conflict, along with the persistence of the pandemic, which seriously risk delaying expected growth consolidation for businesses in the sector. Difficulties in finding raw materials and components negatively affect the completion and fulfilment of orders processed as far back as 2021. To boot, rising energy costs and inflationary trends affecting numerous commodities are depressing overall business confidence. So the outlook for the sector is not so good.”
As such, the two cornerstones through which ACIMIT aims to support the Italian textile machinery sector are digitilization and sustainability.

4.0: The textile machinery sector looks to the future
The road to digital transformation has already led numerous manufacturers to completely rethink their production processes, rendering them more efficient and l ess expensive. The digital world is moving ahead at a decisive rate in the textile machinery sector, where the buzzwords are increasingly, for instance, the Internet of Things connecting to a company’s ecosystem, machine learning algorithms applied to production, predictive maintenance, and the integrated cloud management of various production departments. It is no coincidence that ACIMIT has focused decisively on its Digital Ready project, through which Italian textile machinery that adopt a common set of data are certified, with the aim of facilitating integration with the operating systems of client companies (ERP, MES, CRM, etc.).

A green soul
Combining production efficiency and respect for the environment: a challenge ACIMIT has made its own and which it promotes among its members through the Sustainable Technologies project. Launched by the association as early as 2011, the project highlights the commitment of Italian textile machinery manufacturers in the area of sustainability. At the heart of the project is the Green Label, a form of certification specifically for Italian textile machinery which highlights its energy and environmental performance. An all-Italian seal of approval developed in collaboration with RINA, an international certification body.
The assembly held on 1 July provided an opportunity to take stock of the Sustainable Technologies project, more specifically, with the presentation of the Rina Consulting survey on the Green Label’s evolution and impact in recent years.

The results have confirmed the initiative’s extreme validity. The technological advances implemented by the association’s machinery producers participating in the project have effectively translated into benefits in terms of environmental impact (reduction of CO₂ equivalent emissions for machinery), as well as economic advantages for machinery users.

With reference to the year 2021, a total of 204,598 tons of CO₂ emissions avoided on an annual basis have been quantified, thanks to the implementation of improvements on machinery. This is a truly significant reduction which, for the sake of comparison, corresponds to the carbon dioxide emissions generated by 36,864 automobiles travelling an average of 35,000 km a year. In terms of energy savings, the use of green labeled textile machinery has provided excellent performances in allowing for a reduction of up to 84% in consumption.

A round table discussion on the Green Label’s primary purpose
The environmental and economic impact generated in production processes for Italian textile machinery through the use of Green Label technologies was the focus of the round table which concluded the ACIMIT assembly.

Moderated by Aurora Magni (professor of the Industrial Systems Sustainability course at the LIUC School of Engineering), the debate involved Gianluca Brenna (Lipomo Printing House administrator and Vice President of the Italian Fashion System for Welfare), Pietro Pin (Benetton Group consultant and President of UNI for the textile-clothing area), Giorgio Ravasio (Italy Country Manager for Vivienne Westwood), as well as ACIMIT President Alessandro Zucchi.

Called on to compare common factors in their experiences relating to environmental transition processes for their respective companies, the participants were unanimous: the future of Italian textile machinery can no longer ignore advanced technology developments capable of offering sustainable solutions with a low environmental impact while also reducing production costs. This philosophy has by now been consolidated, and has proven to lead directly to a circular economy outlook.

The upcoming ITMA 2023 exhibition
Lastly, a word on ITMA 2023, the most important international exhibition for textile machinery, to be held in Italy from 8 to 14 June 2023 at Fiera-Milano Rho. Marking the 19th edition of ITMA, this trade fair is an essential event for the entire industry worldwide, providing a global showcase for numerous innovative operational solutions on display. A marketplace that offers participants extraordinary business opportunities. The participation of Italian companies is managed by ACIMIT.

Monforts is introducing a range of modular upgrades that can be added to existing finishing lines already in production.

The Monforts universal Energy Tower – a flexible, free-standing air/air heat exchanger for recovering the heat from the exhaust air flow of thermal processes – can result in a 30% reduction in the energy consumed by a line, depending on the exhaust air volume and operating temperature.

A Monforts Eco Booster, completely integrated into the chamber design of the Montex stenter, is another retrofitting option. As a single state-of-the-art heat recovery system with automatic cleaning, it can be added to existing ranges. For ranges of up to eight chambers only one module is necessary to achieve significant energy savings.

On an eight-chamber stenter with an operating width of two metres carrying out a fixing process on a 150gsm woven fabric, for example, the energy savings have been calculated to be 35% over an annual schedule of 6,000 operating hours.

In addition, the Eco Booster consumes only minimal amounts of water during the cleaning cycle and the entire process is controlled and monitored automatically.

The Matex Eco Applicator is an alternative to the conventional padding process for energy-conscious finishing and achieving considerable savings in the energy required for drying treated fabrics. The precise amount of chemical can be applied to the fabric and with less residual moisture after application of only approximately 35% so that less drying capacity is required in the stenter, which leads to huge energy savings.

Finishes can be evenly applied on either or both sides of the fabric, and two separate treatments can be applied to front and back. This makes the unit ideal for the production of, for example, double-performance hydrophobic/hydrophilic fabrics for professional clothing, as well as the over dyeing or finishing of denim fabrics.

International textile producers meet again in Istanbul, Turkey, from June 14 – 18, 2022 on the occasion of the ITM + Hightex Exhibition. In Hall 9 (Hightex) the exhibitors will present the complete industry value chain from nonwovens raw materials, production machines and accessories to the endproduct. The related industries covered include hygiene, filtration, fabrics and apparel, medical, automotive, wipes, home furnishings and upholstery. DiloGroup offers tailor-made production systems from one supplier and will inform about its portfolio and the latest equipment developments from fibre opening to the finished felt.

DiloGroup will inform about complete lines as well as high speed needlelooms for spunbonds. A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further. The new needle pattern 8000X is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

Another strong pillar of the sales program over decades has been fibre preparation and high speed webforming equipment for other nonwoven technologies. The further development of the high-speed layering principle “Hyperlayer” made progress for better CD strength through a combination of inline cards and crossline card with crosslapper. Particularly, carding machines in a working width above 3.5 m up to 5.1 m have been supplied by DiloSpinnbau as complete high speed carding systems, comprising two or even three cards in a line to directly feed the hydroentangling units of various suppliers. Together with DiloTemafa not only have high throughput rates been achieved in the fibre preparation section of the line but also dedusting filtering and air-conditioning systems have been successfully engineered and integrated.

Together with Sicam, Dilo has combined know-how for hydroentangling technology and therefore can provide complete lines as general contractor including equipment for cutting, winding and packaging.

Another interesting machine is the 3D-Lofter, first presented during ITMA 2019 in Barcelona, which offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts with or without repeat are two examples for this technology which explores new application areas for needlefelts.
The 3D-Lofter technology may also be used “inverted” as “IsoFeed” for filling up bad spots in web mats and thus achieves a better homogeneity of spunlace or airlay products.

The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

Dilo, a leading equipment supplier of complete lines for staple fibre nonwoven fabric production, will exhibit at IDEA 2022 in Miami, end of March.
 
The most recent machine concepts from DiloGroup companies DiloTemafa, DiloSpinnbau and DiloMachines will be promoted with the emphasis on new equipment components which improve product quality, increase line capacity and also enable new opportunities in nonwoven production.
 
DiloTemafa will promote the improved bale opener series “Baltromix Pro” with design features for the operating assistance with the I4.0 components “Bale Timer”, cleaning control, better accessibility for maintenance and the “DI-LOWATT” system for energy savings in fibre transport. The proven carding willow with modified workers and separate drives to create the prerequisites for a good fine opening will also be part of the presentation as well as the fine opening stage which may be installed over the material box of the new card feeder FRS-P to achieve a high dosing accuracy in cross and longitudinal direction.  
 
DiloSpinnbau has a new “Unifeed” card feeder (VRS-P) which combines the principle of volumetric charged feeding with the characteristics of a chute feeder but without the conventional overhead trunk which allows for lower ceiling height requirement. The fibre flock matt is condensed by a vacuum delivery apron to give better uniformity of mass distribution. The distribution over the working width is controlled by additional flaps. This feeder can be adapted for medium/fine, coarse/medium or long staple fibres.
 
The “VectorQuadroCard” by DiloSpinnbau incorporates a modular transfer group between breast and main section. The quick change facility of this roller group provides different carding options. The delivery system is also flexible to provide parallel laid, random or condensed web. The preopener section on this card has 4 worker/stripper pairs with five pairs on the main cylinder. Emphasis is on high throughput with good web quality.
 
The revised HyperLayer NT offered by DiloMachines presents the latest state-of-the-art highspeed precision layering technique setting new standards which play an important role especially in hydroentanglement lines. In this application, it is important to achieve layering speeds up to 190 m/minute using sophisticated viscose fibres and a layering width of about 4 m while at the same time having a high layering precision in cross and longitudinal direction.  
 
DiloMachines will also present its portfolio to improve quality and reduce costs. The FutureLine study “3D-Lofter” – first presented at ITMA 2019 in Barcelona – is part of this programme. In this study individual web forming units can deposit fibre masses on freely programmable spots in longitudinal and cross direction thus saving overall fibre mass in applications such as deep moulded parts for the automotive interior. This ability reduces costs in production and operation. The “IsoFeed” concept for a more even flock mat for direct cards and aerodynamic web forming is another interesting field of web mat quality improvement.

Knopf’s Sohn, a contract finisher of technical textiles, has installed a fully automated Montex stenter at its plant in Helmbrechts, Germany.
Knopf’s Sohn is processing technical textiles for the automotive, aerospace, home furnishings and workwear markets, based on wool, cellulose, polyamide and polyester fabrics, along with elastane blends, in weights of 80-800gsm.

The Montex machinery range is constantly being upgraded to meet evolving customer needs for greater automation, ease of operation and energy optimisation. The latest ten chamber line at Knopf’s Sohn, with a working width of up to 2.0 metres, was engineered to specific requirements in order to accelerate the company’s move to fully automatic control of its production, and high scaffolding was required for its installation.

The line benefits from two integrated ECO Booster modules to provide high energy savings. These compact, air-to-air heat exchangers, installed within the roof structure of the line, exploit energy from the exhaust gas to preheat up to 60% of the incoming fresh air entering the stenter.

The use of a single ECO Booster unit has been calculated to save up to 35% in energy costs, based on fixation processes. Fully automatic operation, set at the Monforts Qualitex control unit, ensures there is no additional burden on the machine operator.

The line is powered by Exxotherm indirect heating, which practically eliminates the yellowing which can be experienced during the treatment of certain polyamide and elastane-based fabrics, and is also equipped with a Conticlean circulating air filter system for constant high drying capacity.

Software
The latest Qualitex visualisation software offers operators reliability and easy control with its full HD multi-touch monitor and slider function, dashboard function with individual adaptation to operating states and faster access to comprehensive recipe data management.

With the Monformatic control system, the exact maintenance of the dwell time in combined treatment processes (drying and heat-setting) can be monitored. When the heat-setting point is reached, the fan speed is automatically adjusted, keeping energy consumption fully under control.
