From the Sector

Monforts has installed and commissioned a new Montex finishing range at the Baltic Works of Halley Stevensons in Dundee, Scotland, to further boost the weatherproofing specialist’s highly flexible operations.

The range, with a working width of two metres, was built at the Montex assembly plant in Austria and consists of a Montex®Coat coating unit in knife execution for paste and foam coating and a Montex 8500 6F stenter.

Founded in 1864, Halley Stevensons has amassed unique technical know-how and manufacturing experience in the art of waxed cotton for weatherproofed fabrics and is able to provide international orders in custom colours and finishes to very low minimum quantities where required. The company exports worldwide and its premium brand customers include Belstaff, Barbours, Filson and J.Crew.

The range has replaced one of the company’s older stenter/coating lines and has already enabled Halley Stevensons to recreate various products with lower coating applications at higher speeds than was previously possible.

Waxed cotton was originally developed by sailors in the early 15th century when Scottish North Sea herring fleets began treating flax sailcloth with fish oils and grease in an attempt to waterproof their sails. Remnants of these sails were used by the sailors as capes to withstand the high winds and sea spray.

By the mid 1850s, sailcloth was being treated with linseed oil, but while initially highly effective, it would yellow and stiffen through weathering over time and eventually lose its waterproofing qualities.

In the years that followed, various treatments were applied to cottons in an attempt to find the most effective weatherproofing solution, and the combination of densely-woven cotton impregnated with a paraffin waxed coating proved most successful. For over 150 years, Halley Stevensons created many different variations of both woven constructions and finishing treatments and now supplies thousands of metres of waxed cotton every year, with each roll produced to custom specifications.

“The beauty of waxed cotton is its durability and longevity,” says Managing Director James Campbell. “The fabrics are breathable, with the wax adjusting to ambient temperatures to be softer and more breathable in warm weather and stiffer and more wind proof in cold conditions.”
While traditional waxes are petroleum or paraffin based, Halley Stevensons has always been comfortable about using a waste product from industry and reusing it to make products that last a lifetime.  

“We are always exploring different finishing techniques and one of our most popular finishes is our hybrid aero – an emulsified blend of waxes,” Campbell says. “This fabric is water repellent but has little wax in the mixture so the handle is much drier to touch than the traditional wet waxes.”

The company has also recently launched a new 100% plant-based wax – Ever Wax Olive – consisting of a blend of olive oil, rape seed and castor bean with comparable water repellence to petroleum and a far better rating than other natural waxes which have come before it.

“The high tradition of skills and fabric innovation imposed by our original guildsmen is still our benchmark standard of honest workmanship today,” Managing Director James Campbell concludes “We use responsibly sourced cotton fabrics and processes that are gentle to the product and low impact to the environment. Our dyeing methods use very low levels of water and our waxes are simply heated up for application and cooled down to store when not in use, meaning no waste discharges. Now, with this new Monforts line, we are also achieving running speeds two-to-three times faster than with the older stenter, combined with less gas usage. It’s proved a great partnership.”

• Partnership with green power producer Enery and Energie Steiermark realizes construction of a photovoltaic plant with 5.5 MWpeak capacity
• Strategic investments in renewables boost energy independence and reduce carbon footprint

The Lenzing Group has signed an electricity supply contract with green power producer Enery and Energie Steiermark to finance a photovoltaic plant in the Deutschlandsberg region (Styria). The electricity generated will supply the fiber and pulp plant at the Lenzing site after commissioning from the fourth quarter of 2023. The electricity supply contract is limited to 20 years.

The plant’s output will amount to 5.5 MWpeak. This corresponds to the average annual electricity demand of more than 1,700 households. Several photovoltaic systems are already being installed at the Lenzing site, including the largest ground-mounted plant in the province of Upper Austria, whose commissioning is imminent.

In 2019, Lenzing became the first fiber manufacturer to set a target to reduce its carbon emissions by 50 percent by 2030 and to be climate neutral by 2050. This carbon reduction target has been confirmed by the Science Based Targets Initiative. Lenzing is also currently investing in reducing carbon emissions at other sites worldwide. Only recently, the Lenzing Group announced that its Indonesian site will also be relying on green energy in the future.

In 2018, Lenzing launched the Lenzing E-Branding Service which allows Lenzing’s customers, retailers and brand partners to effectively use trademarks in their marketing materials. The platform has been welcomed by partners globally as it continues to deliver value to the fashion, textile and nonwoven sectors by facilitating the traceability of Lenzing’s fibers and enabling customers to promote them effectively.

According to the World Health Organization (WHO), cardiovascular disease is one of the most common natural causes of death. Every year, it is the cause of death of around 17 million people worldwide. The Peter Dornier Foundation Prize 2022 has now awarded a research work that is to improve the medical care of people with insufficient heart valve function in the future and prolong the patients' lives.

The human heart is a high-performance machine: over the course of a person's life, it beats almost three billion times, pumping around 200 million litres of blood through the body. Enormous stresses that can sometimes lead to life-threatening signs of wear and tear. If a heart valve gets out of step, patients usually get artificial-mechanical or biological valves as a replacement. However, mechanical solutions imply patients to take blood-thinning medication for the rest of their lives. In addition, there may be audible closing noises. For example, almost a quarter of patients with mechanical heart valves complain of sleep disturbances. Biological heart valves, on the other hand, such as those made from animal tissue, require a great deal of manual work and have a shorter lifetime.

Potential of weaving for medical products demonstrated
For this reason, Graduate Engineer Mathis Bruns at the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) at the TU Dresden is researching an implant alternative made of fabric. As part of a research project that also involved heart surgeons from the Dresden Heart Centre and the University Hospital in Würzburg, Mr. Bruns provided important findings for weaving an artificial heart valve in his diploma thesis. For his work entitled "Development of tubular structures with integrated valve function", Mathis Bruns has now received the Peter Dornier Foundation Prize 2022, endowed with 5,000 euros. In his laudation, Dr. Adnan Wahhoud, former head of the development department of air-jet weaving machines at DORNIER in Lindau, said: "With his work, the winner of the award demonstrates very clearly the potential of weaving technology to produce fabrics of complex form, geometry and structure with the aim of prolonging and improving people's lives." The award-winning thesis enriches research into three-dimensional tissues for use in medicine.

Weaving replacement heart valves without seams
"A particular advantage of our approach is the integral production method", says foundation prize winner Mathis Bruns. “The geometry and function of a heart valve is that complex that woven heart valves could not be produced in this form previously. Through the combined use of a rigid rapier weaving machine with bobbin shield and a Jacquard machine, it is possible to weave the replacement heart valve in such a way that it no longer has be sewn together. Even the tubular structures for the blood vessels and the integrated valve function are ‘all of one piece’. Seams are always a weak point in textile medical products," Mr. Bruns adds. “Another advantage of the woven heart valve is the possibility to insert it by the help of minimally invasive surgery. Hence, the folded valve which is about the size of a tea light is to be pushed with a catheter via the bloodstream to the target position in the heart and unfolded there. The patient's chest and heart would then no longer have to be cut open”, explains prize winner Mr. Bruns.

Textile structure is similar to human tissue
A wide variety of medical products have always been produced on DORNIER weaving machines. Customers use them to produce fabrics for bandages, prostheses, blood filters and orthoses among other things. For Mathis Bruns, it is only evident that implants such as heart valves will more and more be woven on the machines from Lindau in the future. "Textile tissue is very similar to human tissue," he says. The human body consists largely of thread-like materials, just as a textile fabric is made up of thousands of individual threads. "Muscle fibres convey force impulses, nerve tracts send stimuli such as pain and brain cells convey information via thread-like dendrites and axons." Because of their ‘thread-like properties’, woven implants are therefore particularly suitable for medical applications.

EFI™ Reggiani, the industrial textile printing business of printing technology company Electronics For Imaging, Inc. (EFI), has broken ground on a new textile campus to accommodate ongoing growth. The new 20,000-square-metre campus in Comun Nuovo, Bergamo, Italy, is expected to be completed midyear in 2023.

Sustainability and employee well-being at the centre
The new facility was designed with environmental sustainability and employee well-being in mind. That focus includes plans to install 400 kilowatts of solar panels supplying 60% of the facility’s total energy requirements. Moreover, the building will benefit from superior thermal insulation that will ensure a reduction in heating and cooling costs. Numerous skylights in the facility will provide better natural lighting and a reduction in artificial lighting usage.
 
Green space on the campus was a priority in the design process, covering an estimated 20% of the total area. For a more welcoming work environment, the campus will also feature a canteen and gymnasium for employee use.
 
A 3,000-square-metre demo centre in the new facility will be nearly twice as large as the current EFI Reggiani demo centre in Grassobbio, Italy, offering a high-end, high-tech showcase for state-of-the-art EFI Reggiani printers, as well as Mezzera pre- and post-treatment and Jaeggli yarn treatment products. The demo centre will also feature EFI Reggiani’s recently acquired portfolio of Inèdit raster image processing (RIP) and workflow software solutions.

Since the launch of its first analogue printer, to its newest digital solutions, EFI Reggiani has at its core a heritage and expertise that have contributed to the transformation of the textile industry worldwide. With its total commitment to providing “Innovation in Green,” EFI Reggiani’s leadership is the result of extensive research targeted at improving productivity, quality and sustainability in its customers’ operations. The company is focused on optimising the textile manufacturing process – and reducing energy use, water consumption and overall environmental impact – to ensure customers’ business growth and profitability.
 
Over the years, EFI Reggiani’s product portfolio has continued to expand, ranging from rotary and flatbed printing machines, to scanning/multi-pass digital printers, to fast digital textile printers.

• 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.

Catering to the acoustic requirements of electric vehicles, Autoneum has extended its concepts for noise-reducing engine encapsulations to new applications related to electric drives. Hybrid-Acoustics PET and the foam-based alternatives Hybrid-Acoustics FLEX and Fit FLEX ensure optimum noise protection in e-cars and thus improve driving comfort. All three technologies are characterized by a high acoustic performance tailored to specific customer needs and zero waste production.

Disturbing noises such as the high-frequency sounds of e-motors and other electric devices or the whining noise of the gearbox are posing new acoustic challenges for vehicle manufacturers worldwide. Anticipating the increasing demand for sound-reducing components in both the front and the rear of e-cars early on, Autoneum has expanded its technologies for noise protection in the engine bay to new tailor-made applications for electric vehicles.

With the fibrous technology Hybrid-Acoustics PET and the two foam alternatives Hybrid-Acoustics FLEX and Fit FLEX, the Company offers three standardized technologies that reduce noise directly at the source, thereby improving driver comfort. All three technologies are produced waste-free and their adaptive capacity to different sizes and shapes allows for a broad spectrum of uses in electric vehicles: from e-motor encapsulations to the reduction of noise and vibration of inverters, gearbox, pumps and compressors. By offering both fibrous and foam-based variants, Autoneum is able to flexibly cater to individual customer needs and preferences with regard to material, acoustic concept, sustainability and costs.

In terms of sustainable noise protection in the engine bay, Autoneum’s patented innovation Hybrid-
Acoustics PET sets the tone: it is made of 100 percent PET with up to 50 percent recycled fibers; cut-offs in production are reclaimed, processed and reused and the material can be fully recycled at the end of product life. The unique textile technology, which is part of the Company’s sustainability label Autoneum Pure, is particularly suited to attenuating high-frequency sounds of the electric drive unit and offers the optimum balance of absorption and insulation. Moreover, components made of Hybrid-Acoustics PET are up to 40 percent lighter compared to standard insulators.

To accommodate the differing preferences of vehicle manufacturers, Autoneum has complemented its lightweight textile technology with two foam-based alternatives. Since the foam is injected in both technologies, no waste is generated during production either. Hybrid-Acoustics FLEX is based on the same acoustic concept as Hybrid-Acoustics PET, but the decoupler is made of foam instead of felt. Autoneum’s Fit FLEX, on the other hand, combines the foam decoupler with an injection molded heavy layer. Thanks to the high geometrical adaptability of foam to even complex shapes, both technologies offer outstanding acoustic performance in the insulation of e-motors and other noise sources in electric vehicles. Furthermore, the absorbing or insulating acoustic quality of the foam can be flexibly tuned to specific customer needs.

Natural fibers are among the most important raw materials in the textile and fashion industry worldwide. For centuries, they have fed millions of people through their cultivation or breeding, and it is impossible to imagine daily life without them. Especially at the moment, natural fibers are gaining special importance due to the intense discussions about sustainable living. Even though natural fibers have accompanied mankind for a long time, they are changeable, technical, and adaptable to the challenges of the textile industry.

The Discover Natural Fibres Initiative (DNFI) is celebrating natural fibres in a program to be conducted during Heimtextil in Frankfurt on 23 June. Anyone with an interest in the role of natural fibres in the world economy, economic indicators of textile activity, innovations in natural fibre research, and updates on proposed EU legislation affecting textiles is welcome to attend.

The program will include various presentations by the previous and current award winners, presentations, and discussions:

Overview of world natural fibre production, employment, and value,

• Economic indicators and impacts of coronavirus on textile industries,
• Updates on innovative uses of natural fibres:
• Use of wool in automobile insulation applications for enhanced sustainability,
• Using cellulose from cotton to produce a biodegradable plastic substitute,
• Manufacturing waterproof fabric from a blend of cotton and jute as sustainable
• Substitute for polypropylene tarps
• Proposed EU textile legislation and potential impacts on natural fibres

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Baldwin, a leading global manufacturer and supplier of precision spray systems and technology for sustainable textile manufacturing, announce a new collaboration to optimize performance and resource saving in the finishing department.

The two companies aim to support textile manufacturers in their development projects, targeting to improve their product safety, performance and functionality, while at the same time maximizing the productivity and resource utilization of the finishing application process.

Archroma and Baldwin are collaborating in multiple projects that combine Archroma’s most sustainable product innovations with Baldwin’s Texcoat G4.

TexCoat G4 is a non-contact spray technology for textile finishing and remoistening, designed to allow a controlled and optimal coverage of the exact amount of finish chemistry for reaching specific characteristics of the fabric. The system can be used to reduce water consumption by as much as 50% compared to traditional padding application processes.

Archroma and Baldwin are currently testing Archroma’s finishing products and systems, such as the soon-to-be-launched PFC-free* Smartrepel® Hydro SR for water-based soil repellence, as well as metal and inorganic particle-free antimicrobial technologies like Sanitized T 20-19 and TH 15-14, which will be launched at the upcoming Techtextil 2022.

The first test results will be available for discussions with both partners at Techtextil at their respective booths.

Focus on eccentric screw pumps and pumps for shear-sensitive materials

Improved productivity and increased lifespan and tailored solutions also for the most demanding applications within the chemicals and plastics industries and in PUR applications – these are the convincing arguments with which Oerlikon Barmag is showcasing its precision metering pumps at this year’s ACHEMA between August 22 and 26, 2022 in Frankfurt. The focus is on the new pump for shear-sensitive conveying media and the new eccentric screw pump.

Eccentric screw pumps – robust all-rounders convey any medium
The requirements for pumps are considerable, as the demand for customized solutions for increasingly complex processes is rising. This is particularly true for Oerlikon Barmag’s new eccentric screw pump range. High wear-resistance, increased durability and robust operation – the new pump is tailor-made for conveying highly-filled, high-viscosity and abrasive media, such as filled adhesives, filled silicones and filled casting compounds, for example. The is the multi-stage seal system, which considerably increases the pump’s lifespan. The upstream shaft sealing ring protects the slide ring seal against excessively-fast wear caused by challenging media. In turn, the optimum alignment of the drive shaft – ball bearing-supported and centrally-guided through the shaft sealing ring – prevents any metal debris caused by friction and hence ensures considerably greater durability. Producers benefit from considerably greater productivity, as the pumps’ maintenance intervals and hence machine downtimes are significantly reduced.

New pump for shear-sensitive materials
For increasingly complex customer-specific process solutions, Oerlikon Barmag is now expanding its GA series, developed especially for the challenging conveying of high-viscosity media, to include the GAB51F for shear-sensitive conveying media. The newly-developed pump with its viscosity range of max. 300 Pas is tailored to conveying high-viscosity, shear-sensitive materials such as adhesives and silicones, for example. “The shear forces impacting the medium within the pump are reduced to a minimum as a result of a specially geometry”, explains Thorsten Wagener, Senior Sales Manager within the Pump Construction business unit. The material is conveyed through the pump in an as gentle and low-pulsation manner as possible and metered precisely at the outlet – ensuring it retains its characteristic properties.

High-speed metering pump with sealed product space
The high-speed metering pump has been especially developed for metering poorly-lubricating media. Here, the main benefit is the sealed product space, which extends the pump’s lifespan considerably. The space that comes into contact with the media is limited to the area around the gears. “As a result, the high-speed pump is particularly suited for applications in the chemicals industry, which frequently involve aggressive acids”, comments Thorsten Wagener.

GM series for low-viscosity media
The pumps in the GM and GA series provide precision metering with low-pulsation feeding of the conveying medium. The multi-stage GM pump conveys low-viscosity media (i.e. 250 bar, 100 mPas) even under high pressure and in the most challenging conditions. The square design from the proven GM series is the standard pump for many metering tasks. The development of the multi-stage pump expands the applications range for the GM series considerably. The round 2-stage GM pump has been developed especially for use in high-pressure technology. It masters the particular challenge of conveying small throughputs with low viscosities. The pump is perfect for 0.05 through 20 cm³/rev feed sizes and is excellently suited for use in high-pressure machines for PUR molded parts, foam slab stock, refrigeration unit insulations and sandwich panels, for example.

GA series pumps for high-viscosity media
The Oerlikon Barmag GA range has been especially developed for the challenging conveying of media with higher viscosities. The GA series pumps are available for conveying volumes of between 1.25 and -30 cm³/rev (0.6-144 l/h). They have been designed for pressures of up to 200 bar, for viscosities of up to 1.500 Pas as well as for temperatures of up to max. 225 °C. With this range of pumps, Oerlikon Barmag offers its customers tailor-made solutions for many technical processes in which high-precision and even metering is of paramount importance.

The drum pump – conveying and metering using a single unit
With the drum pump, the Oerlikon Barmag pump specialists have created a pump designed specifically for conveying and metering high-viscosity materials such as adhesives, silicones and other high-viscosity materials from drums and other large containers and for pressures of up to 250 bar. Its special features not only include the fact that it removes high-viscosity materials from the drum, but that it also meters the medium directly without any additional interim stops.
