From the Sector

KARL MAYER GROUP has developed a sophisticated system for considerable energy savings when operating the cylinder dryers in its PROSIZE® sizing machines and BLUEDYE dyeing plant.

Saving costs with inline energy recycling
The innovation is called CASCADE and focuses on steam as a heating medium in cylinder dryers. And for good reason: according to the IPCC report by ITMF Zurich, one tonne of steam cost between USD 20 and just under USD 27 internationally in 2021. The new solution relies on reuse to reduce the amount of process energy required.
"CASCADE recirculates parts of the process steam in cylinder dryers, enabling genuine, efficient energy recycling within the machine," explains Karl-Heinz Vaassen, Head of Textile Drying at KARL MAYER.
The customer benefits from significantly lower energy costs and CO2 emissions. With a view to the Asian market, a dryer with 14 cylinders and a running time of 7,000 working hours can achieve cost savings of up to USD 17,000 per year.

Precise, real savings values are available when looking at the machine dashboard. A sensor provides real-time data on the amount of steam circulating in the circuit, from which the corresponding reduction in CO2 equivalents can be calculated.

Utilizing the pressure drop
CASCADE reuses part of the invested process energy and uses the flash-steam in conjunction with the pressure ratios, which - nomen est omen - decrease in cascades in the different zones of the cylinder dryer.
The highest working pressure prevails in the first cylinder section. The heat transfer medium steam emits large amounts of energy for yarn drying and condenses without temperature loss.

The resulting hot condensate is not immediately discharged from the machine, but is instead fed into a flash tank, where vapor exhaust is formed as a result of the pressure reduction. In conventional systems, the carrier medium for gases is only created in the return line towards the boiler house and is eliminated as undesirable. Instead of being utilised in the process, it escapes into the environment. With the CASCADE system, this "freshly recycled steam" is used for the heat supply in the second cylinder section, but not without prior treatment.

In the system patented by KARL MAYER, the recycled steam is intelligently mixed with live steam and thus raised to the level of the required process conditions for use in the cylinder section at the end of the dryer. Here, the fabric moisture is reduced to the desired residual value at medium pressure and temperature conditions.

Market launch is underway
CASCADE was filed for patent by the KARL MAYER GROUP. It was published in September 2023.
The innovative solution at no extra charge was presented at ITM 2024 in Istanbul and was a visitor highlight at the KARL MAYER GROUP stand.

From January 2024, CASCADE will be part of the PROSIZE® as standard. The first sizing machine with the upgrade for greater energy efficiency will be delivered in the second quarter of this year. It will go to a manufacturer in Europe. In the next step, CASCADE will be integrated into other dryer types and will also be available for the BLUEDYE.

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.”

ITMA ASIA + CITME, Asia’s leading trade fair for textile machinery, took place in Shanghai with a considerable presence of VDMA member companies. The round about 40 exhibiting VDMA members covered nearly all different machinery chapters with a focus on spinning and manmade fibers, nonwovens, weaving, braiding, knitting & hosiery, finishing & dyeing and textile processing. They were part of a strong German presence with a total of around 60 German exhibitors – including non-machine manufacturers.

During a press conference on the first day of the show, Dr. Janpeter Horn, chairman of the VDMA Textile Machinery Association and managing director of August Herzog Maschinenfabrik expressed: “After years of cancelled or postponed trade fairs and travel restrictions, this year’s ITMA ASIA + CITME is the first edition of the show that can be attended not just by Chinese but by visitors from various countries and regions. The event is a good opportunity to meet customers and partners again in person and not just on a screen. ITMA ASIA + CITME provides a good chance to deepen the already good relations with China and other Asian countries further and to set-up new partnerships.”

Dr. Horn continued to present latest facts and figures about the German textile machinery industry. Between January and August 2023, the overall exports of textile machinery and accessories summed up to 1.7 billion euros, which was a slight decrease compared to the same period in 2022. The shipping to almost all major markets decreased between January and August: China: 440 million € (2022: 453 million €), Turkey: 205 million € (2022: 265 million €), USA: 177 million € (2022: 144 million €), India: 170 million € (2022: 228 million €).

Numerous VDMA member companies have production sites in the major Asian markets China and India and serve their customers in these countries from there. A latest VDMA business climate survey among the textile machinery companies in China showed, that 75% of all participants assessed their current business situation as either good (6%) or satisfactory (69%). For the coming quarter, 50% of the companies see the market to decline. Asked about the business situation during the next six months, 44% of the companies expect the market to remain stable, 56% expect the situation to become worse. This is also reflected in the HR of the companies: 63% expect the number of employees to remain unchanged.

Members of TMAS – the Swedish Textile Machinery Association – will be taking part in the forthcoming ITMA Asia + CITME exhibition, taking place from November 19-23 2023 at the National Exhibition and Convention Centre in Shanghai, China.

Weaving
In the area of weaving, 93% of the 114,000 new looms delivered in 2022 went to Asia, according to the latest figures from the International Textile Manufacturers Federation (ITMF), with China the top destination, followed by India.
As a result, TMAS members like Vandewiele Sweden AB and Eltex have a huge market to address that has been established over many decades.

Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of the market-leading Vandewiele Group, supplying weft yarn feeding and tension control units for weaving looms to the majority of weaving machine manufacturers. It also retrofits its latest technologies to working mills to enable instant benefits in terms of productivity and control.

Yarn and sewing thread monitoring
With nearly 70 years of expertise in yarn sensor technology, Eltex of Sweden AB has been at the forefront of new product development. Its EYE and EyETM systems are capable of accurately and efficiently monitoring the movement and tension of more than 1,000 yarns simultaneously. These systems are suitable for various applications and fibre types, including warping, winding, multiaxial weaving and new material applications.

Eltex sewing tension monitors, such as the ETM422, have been well-received by customers. This device can monitor the tension of sewing threads in real time, effectively improving the quality and safety of sewn products. Particularly in China's rapidly growing automotive manufacturing sector, the ETM422 has seen widespread use to meet the industry’s escalating demands for product safety and quality.

Dyeing and finishing
“Digitalisation, automation and AI have become the key enablers for sustainable gains across the entire textile industry and so much has been achieved in the past few years, especially in terms of automation,” says TMAS secretary general Therese Premler-Andersson. “One area in which TMAS members are really making a difference right now, is in replacing water and energy-intensive technologies for the dyeing and finishing processes with new digital technologies.”

The TexCoat G4 non-contact spray technology for textile finishing and remoistening, for example, will be showcased in Shanghai by Baldwin. It not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to a customer’s requirements in terms of single and double-sided finishing applications. The TexCoat G4 can reduce water consumption by as much as 50% compared to traditional padding application processes.

Finishing machinery specialist Monforts has secured a number of major orders from textile manufacturers in Central and South America recently, and was pleased to welcome a high number of visitors from the region to its stand at ITMA 2023 in Milan from June 8-14.

Among new orders are those for three Montex stenters delivered to the AustralTex Group in Argentina and a further Montex range to denim manufacturer CIT in Brazil. Guatemala’s Global Textiles placed an order for its second Montex stenter, while Mexico’s Zentrix ordered its third and Avante, also in Mexico, has opted for its sixth.

Elsewhere, orders have also been placed for the delivery of three new Montex stenters to one of Pakistan’s major corporations, as well as a new Thermex dyeing range to nonwovens manaufacturer Orsa in Italy. Further orders – both for new machines and retrofit modules – are now anticipated following ITMA 2023, which attracted over 111,000 visitors to Milan.

“Visitor footfall at ITMA 2023 was well beyond the company’s expectations, and we were especially pleased at the constant number of visitors from South American companies, as well as from Asia and Europe,” said Monforts Marketing Manager Nicole Croonenbroek. “We were able to provide them with detailed information about our portfolio of machines and technologies digitally and fielded an unprecedented number of serious enquiries, many of which promise to turn into new business.”

Monforts Montex stenters for processes such as drying, stretching, heat-setting and coating, she added, are already the industry standard for the fabric finishing industry, providing a number of advantages in terms of production throughput and especially in energy efficiency and resource savings. Other key technologies in the Monforts portfolio include relaxation dryers, Thermex dyeing ranges and Monfortex compressive shrinking ranges.

Montex®Coat
“We were also very pleased with the interest in the Montex®Coat, the latest addition to our range of technologies, which we displayed in Milan,” Croonenbroek said.

The Montex®Coat can serve a very diverse number of markets and enables full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments, as well as solvent coatings. Knife coating, roller coating or screen printing can also all be accommodated with this system. It provides the ultimate in flexibility and the ability to switch quickly from one fabric run to the next, without compromising on the economical use of energy or raw materials.

Many refinements have been made to the Montex®Coat in the past few years, resulting in higher coating accuracy and the resulting quality of the treated fabrics. A number of advanced new improvements were introduced in Milan, including automatic edge limiters for immediately adapting to new coating widths and a new and simplified hand-held control device. These save considerable time in setting up the machine and ensuring consistent production.

The Montex®Coat unit displayed in Milan was sold to Vietnamese company Thai Tuan during the show.

At ITMA 2023 in Milan from June 8-14, Fong’s Europe will introduce its latest THEN Synergy Airflow and THEN Airjetwin machines, which exploit the principle to provide high-quality, efficient and eco-friendly dyeing processes for a variety of fabrics.

“THEN introduced its first machines with Airflow technology in 1980 and since then we have had wide experience of pretreating and dyeing with Airflow transport systems on all kind of fabrics,” says Fong’s Europe Director of Sales and Marketing Richard Fander. “Our team of engineers has collected data on dyeing processes, results and consumption figures for years and constantly makes use of this accumulated know-how to optimise the processes of our customers.

“The THEN team understands Airflow dyeing processes and technology based on it guarantees the lowest liquor ratio on round shape machines. The transport of fabric by air reduces the liquor ratio compared to every kind of hydraulically driven transport system.”

He adds that while not every fabric can be dyed and treated on Airflow machines with the same handle and appearance as on hydraulic round shape or long shape machines, where it is applicable, it can lead to significant savings of up to 35% in water, 50% in salt, 20% in dyestuffs and 30% in process time.

The THEN Airflow dyeing machines have several features, including several parallel functions for reducing process time. The VPR system shortens the rinsing time and water usage and the robust and homogeneous spraying device in the nozzle ensures a uniform dyeing in the shortest process time. The very short liquor ratio also reduces the use of salt and chemicals.

Montex Maschinenfabrik – the key site for the manufacturing of Monforts finishing machines in Austria – has celebrated its 40th anniversary in 2022.

Located in St. Stefan, in the centre of Austria’s Lavant Valley in Carinthia, the advanced manufacturing hub was founded by Monforts in 1982.

“From the outset, we have specialised in all aspects of machine production, including high-precision sheet metal working, laser cutting and welding, and the pre-assembly of machines and components, , along with a well-organised quality management and spare parts service,” says Montex plant manager Gert Hanzl.

“We work very closely with the Monforts research and development team in Mönchengladbach, Germany, to take the latest new ideas through testing and prototyping, in readiness for future series production,” Hanzl says. “We are fully exploiting the many new possibilities in the continuous development of design and manufacturing methods. The respective electrical switch cabinets for the machines are delivered just-in-time from Monforts in Germany according to our production schedules.”

While there is standardisation in series-produced Monforts machines, Montex is also increasingly called upon to construct bespoke machines with unique designs, according to the special needs of customers in technical textile or special textiles, he adds.

The core Monforts machine range, including the industry standard Montex stenters, along with relaxation dryers, Thermex dyeing ranges, Monfortex compressive shrinking ranges and Montex®Coat coating units is built at the Austrian site.

As part of an ongoing investment programme ensuring it remains at the forefront of advanced technology for carpet production, West Yorkshire, UK-headquartered Phoenox Textiles has recently installed a new two-metre-wide shearing line supplied by BTMA member Sellers Textiles Engineers.

Phoenox, which has been family owned since its foundation in 1954, develops original creative flooring design concepts for retail brands. Its products are sold through high street outlets, department stores and volume retailers across Europe and North America, in addition to substantial online and catalogue-driven business. All told, the company’s 24-hour parcel service dispatches some 3.2 million orders every year.

Operating from two manufacturing sites, Phoenox manufactures an annual 1.7 million metres of flooring in the UK. Over a combined area of 1,700,000 square metres, the two plants are equipped for tufting, backcoating, cloth printing and finishing along with automated cutting, sewing and packing.

In addition to the Sellers shearing line, other recent investments for the UK operations have included three new advanced tufting machines and a high-speed Sellers backcoating line equipped to handle widths of up to two metres and coat at six metres per minute. Washable and dyeable foams and eco-friendly applications in different weights are applied for many product areas.

The company’s state-of-the-art Chromo jet printing process line is meanwhile the only one of its kind in the UK, with its 256 jets making possible designs in up eight colours per pattern. With sustainability very much at the forefront of the company’s approach, Phoenox recycles most of its paste and inks and uses organic options wherever possible, as well as recycled water.

“We operate a piece dye colour cloth programme and can dye nylon and cotton with weights of up to 500kg per load, working with direct, organic, vat and reactive dyes,” says Mosley. “We also offer computerised and weighed commission dyeing. Computerised automated cutting machines and photocell pattern recognition enable us to cut at high speed in most cloth densities. With finishing and sewing though, it’s all about the detail, and our team have years of experience and hand-finish our products on traditional high-speed machines.”

The new Sellers Hybrid Shearing Cylinder can provide a competitive edge for manufacturers which is currently being proven in the field, including at Phoenox. It’s one of a number of new innovations BTMA members are planning to showcase at next year’s ITMA exhibition in Milan.

The identification of profitable new niche markets has been central to the success and continuous expansion of Germany’s Dolinschek, a leading knitting, dyeing and finishing specialist, located in Burladingen in Baden-Württemberg.

“There is so much more to textiles than just clothing,” says Theo Dolinschek, who runs the company with his brother Erwin. “We handle many different technical materials such as automotive components, geotextiles and wallcoverings, but also those for more unusual applications such as inlays for extractor hoods, cut protection fabrics and even wool felts which are employed as insulation on wind turbines.

“We have also recently started to produce compression stockings in a variety of colours, because not everyone wants them black, beige or skin coloured. The most important product areas for us now are in sportswear, corsetry and lingerie, as well as orthopedic and medical products, workwear and protective clothing, but in addition, many other technical applications.”

The Dolinschek brothers moved their business to the historic site of the former Ambrosius Heim textile company in Burladingen in 2001 in order to expand. At the time, the company – founded by their father in 1980 as a textile wholesaler before moving into dyeing – employed just 13 people. Within a year, the company had bought additional space at the site.

Now, with Theo in charge of technology and sales, and Erwin responsible for production, the company employs almost 100 people and operates on an integrated site of 35,000 square metres.

In 2005, a laminating department was established by the company and since 2012 investment in knitting machines has been ongoing.

“The further we went into vertical integration, the more of our own products we were able to position on the market and so we were also able to make ourselves more independent,” says Theo. “We have continued to develop and today we can produce high-quality fabrics for many fields, with 42 knitting machines, 36 dyeing machines, three stenter frames and many other production and processing machines.”

Dolinschek has also developed its own proprietary TMG dyeing machines which have subsequently been successfully sold to many other companies all over the world. There are currently 11 of these machines  in operation at the Burladingen site and around 45 installed at other companies.

For finishing technology, however, the company relies on Monforts, and has installed a new seven chamber Montex TwinAir stenter range with a Montex®Coat coating unit in knife execution, enabling the coating of dimensionally stable knitted fabrics with polyurethane or acrylate. Another unique feature is the Teflon-coated (non-stick) transportation belt through the system.

The Montex line is also equipped with integrated heat recovery and exhaust gas purification to ensure the most resource-efficient processing available on the market. The exhaust air goes from the Monforts heat recovery system into an existing air/water heat recovery system and then into an electrostatic precipitator.

Highly-intuitive Monforts Qualitex visualisation software allows all machine functions and process parameters to be assessed and controlled easily.

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.”
