From the Sector

imogo is a new Swedish company formed by a team with long experience in textile processing technology. It is now boldly aiming to change the face of the textile manufacturing industry with its new Dye-Max spray dyeing technology, to be introduced to the market at ITMA 2019 in Barcelona.

While still at the prototype stage, and with a first full-scale line currently under construction and due to be demonstrated this Autumn before delivery, the DyeMax nevertheless promises to slash the use of fresh water, waste water, energy and chemicals by as much as 90% compared to conventional jet dyeing systems.

Spray cassettes
Its application unit consists of a closed chamber containing a series of spray cassettes with precision nozzles for accurate and consistent coverage, in combination with the patented imogo pro speed valve that controls the volume to be applied. The chamber is equipped with an exhaust system and droplet separator to ensure that the environment around the unit is free from particles.

“The spray cassettes are a key part in the Dye-Max line,” explains Imogo’s founding partner Per Stenflo. “There is one set of spray cassettes for each of the three separate dye dispersion feed lines and they can be easily exchanged without the need for tools in less than a minute. This allows for extremely fast changeovers between different colours without the need for cleaning. And because the spray cassettes are removable, all maintenance can be performed off line. 
After applying the dye dispersion the fabric is rolled onto a shaft and moved to the autoclave for deep dye fixation via heat and pressure.”

The savings in treatment water the Dye-Max achieves are due to the extremely low liquor ratio of 0.5 litres per kilo of fabric Stenflo adds. 

“At the same time, the low liquor ratio and the spray process require considerably less auxiliary chemistry to start with, and all of it is used in the process, which also greatly reduces the production of waste water, with only 20 litres being required for wash at changeovers. The low liquid content in the fabric meanwhile minimises the energy needed for fixation.”

The Dye-Max has a working speed of up to 50m/min with the practical speed determined by the fabric weight and application volume. 
 

A focus on customer service, aligned with the drive to constantly innovate, has long ensured that the member companies of TMAS – the Swedish texile machinery manufacturers’ association – stay well ahead of the curve.

“All of the Swedish textile machinery companies are doing really well in major markets such as Europe, China, India and the USA,” says TMAS Secretary General Therese Premler-Andersson. “They are now gathering forces to prepare for the most important show – ITMA 2019 in Barcelona in June. I expect to see new players and partnerships as we enter the industry 4.0 era for real. We are ready to display an even higher degree of the real time monitoring of processes, automation, flexible customisation, and the incorporation of robots into production lines.  Our customers expect a lot of in terms of knowledge and our ability to customise and offer turnkey solutions.”

The forward-looking attitude of the Swedish companies is perhaps best summed up by Reimar Westerlind, the owner, since 1961, of ACG Gruppen.
At the age of 90, Reimar still travels to his office every day to oversee the operations of the diverse companies operating under the ACG umbrella.
“Everything now is about automation and digitisation,” he says. “We have to be on that track or we will be lost – innovate or die.”

Robotics
One ACG Gruppen company moving rapidly forward with new innovations in this area is ACG Kinna, which at ITMA 2019 will be providing dramatic live demonstrations of its new robotic pillow filling system.
This has the ability to fill and finish some 3,840 pillows per eight-hour shift, which is a considerable improvement on what is currently possible with existing systems, resulting in significant savings in both labour and energy for busy home textile businesses.

At ITMA 2019, Eton will be demonstrating a complete material handling solution with advanced software providing real-time information covering every aspect of the process.
“Our systems are a natural fit with the major Industry 4.0 networked manufacturing plants that are now being constructed worldwide for sectors such as the garment and home textiles manufacturing and automotive industries,” says Eton’s Sales and Commercial Director Roger Ryrlén.

Sensors
Advanced senor developments are playing a large part in moving many areas of the textile industry forward too.
Eltex of Sweden, for example, is achieving considerable success with its yarn fault detection and tension monitoring systems across a range of sectors, including the tufting of carpets, the creeling of woven materials and even the production of woven reinforcements for the composites industry.

At successive ITMA shows, IRO AB has also consistently introduced new milestones in the field of yarn feeding technology for weaving machines, and ITMA 2019 will be no exception.
“Following significant investment in our R&D capabilities, we have been making great progress in further boosting the efficiency and performance of our expanding X3 range,” says IRO AB Managing Director and Chairman of TMAS Mikael Äremann. “I can’t remember a time since the 1980s when we had so many new innovations to unveil at an ITMA, and I’m greatly looking forward to the positive response to them we are anticipating in Barcelona this June.”

Resource savings
ITMA 2019 will meanwhile see the launch of TexCoat G4 – the next generation of Baldwin Technology’s non-contact precision application system for fabric finishing. The TexCoat G4 enables a continuously high-quality and productive textile finishing process with zero chemistry waste and minimised water and energy consumption.
The non-contact spray technology brings a range of advantages including single or double-sided application,  the elimination of Foulard bath contamination, low wet pick-up levels leading to the elimination of drying steps, zero chemistry waste in changeovers of chemistry, colour or fabric, and the possibility of batch reporting, visibility of pad loading, chemical usage etc.

Other TMAS companies exhibiting in Barcelona include Texo AB, whose wide-width weaving looms make the belts for machines on which half of the world’s paper is made, ES-Automatex, which specialises in bespoke automation concepts and Svegea, a company leading the field in a number colarette machines and cutting and slitting equipment.

“At the last ITMA in 2015 in Milan, there was much talk about Industry 4.0 technologies but certainly from the perspective of TMAS, ITMA 2019 will be the place for concrete solutions as to how data and the new tools we have available can be exploited to the full,” says Therese Premler-Andersson. “There is already much more networking between the companies, with software very much the enabler and common interfaces bringing ideas closer together. We are greatly looking forward to further exchanges of ideas when meeting with customers old and new in Barcelona.”

FONG’S EUROPE, based in Schwäbisch Hall, Germany, will celebrate the 100th anniversary of its flagship THEN brand for advanced dyeing technology with a special reception for customers and agents at ITMA 2019 in Barcelona.

The company, which has been a member of the CHTC FONG’S group since 2004, has its origins in the German city of Chemnitz, where back in 1919 Rudolf Then founded a barrel-making business which soon branched out into piece dyeing machines.

The company’s reputation for innovation began early, with the introduction of ceramic linings for dye baths, which were then made of wood, in order to avoid staining and allow easy cleaning. At the end of the 1920s, Rudolf Then was also quick to recognise the acid-resistant advantages of stainless steel for dyeing vessels.

Relocating to West Germany after World War 2, Rudolf Then ran a number of businesses in Schwäbisch Hall, eventually founding THEN in 1955 with partner Karl Kurz, who later took over the business specialising in dye vats and other textile equipment.

Throughout the 1960s and 70s, the company continued to further improve its technologies, but it was the introduction of the first THEN AIRFLOW system at ITMA 1983 in Milan which significantly boosted the company’s fortunes, representing a milestone in the development of dyeing machines.

Prior to this, the dyeing of just one kilo of fabric required around 150 litres of water and THEN’s AIRFLOW system, invented by engineer Wilhelm Christ and colleagues, drastically reduced the requirement to between just 35-40 litres. Instead of the traditional dye liquor used for hydraulic fabric transport it efficiently distributed much smaller amounts of dye liquor via aerosol. This technology has subsequently been further developed in successive machine models and has made an enormous impact on sustainable dyeing operations.

Now, as FONG’S EUROPE, the company continues to innovate, and at ITMA 2019 is showcasing the THEN SMARTFLOW TSF hydraulic high temperature dyeing machine, designed to achieve the lowest possible energy and water consumption rates available on the market for jet dyeing.

The company has a number of patents pending on the innovative new features of this machine, including the SMARTFLOW’s fabric transport design. This is based on a smart, winchless fabric transport system which eliminates the need for a loading rope, and a circular plaiter with programmable rotation speeds which provides full filling of the drop zone.

Its newly-developed nozzles and reel-less transport, in combination with smart controlled circular plaiting and variable chamber adjustment, provide even fabric treatment without entanglements and the highest loading capacity with the lowest kier volume

“Further developments, including the new THEN AIRFLOW PLUS system with a round design are in the development pipeline and will once again result in further reductions in power consumption without sacrificing performance,” says FONG’s Europe Sales Director Richard Fander. “Similar innovations are being made to our hydraulic long shape machine, the THEN SUPRATEC LTM. The ability to transport fabrics with reduced tension and without the need for a transport winch which is being introduced on all of our recent machines will allow new fabrics to be created and further increase the efficiency of textile finishing.

Fong’s Europe will be at stand D101 in Hall 2 at ITMA 2019.

• Innovative BCF S8 platform technology opens up new carpet yarn industry markets for Oerlikon Neumag customers

World premiere at the DOMOTEX World Trade Fair for Carpets and Floor Coverings in Hanover: between January 11 bis 14, 2019‎, Oerlikon Neumag will be showcasing its innovative new development, the BCF S8, to a wide audience for the very first time in Hall 11, Stand B36. Whether commodities or niche products – the new BCF S8 platform technology offers manufacturers of BCF carpet yarns decisive arguments for responding to constantly rising cost pressures and the trend for greater efficiency and quality in fiercely-competitive markets. World record: the system achieves never-seen-before spinning speeds and is able to simultaneously spin up to 700 filaments and produce fine titers of up to 2.5 dpf. This superlative performance is guaranteed by numerous individual innovations in the new platform and, for the first time, also in a new human-machine interface (HMI)-based control system, which opens the door to the digital age of smart carpet yarn manufacturing wide. At the ITMA ASIA 2018, the Oerlikon Manmade Fibers segment had already announced that it would be presenting revolutionary solutions in 2019 – both in hardware and software. And the DOMOTEX marks only the start.

According to manufacturer information, the new BCF S8 is the most efficient Oerlikon Neumag BCF system of all times. “We have succeeded in achieving a new level of greater productivity and even broader product diversity. These allow our clientèle to better cater to changing market requirements and achieve a competitive edge in tough market conditions”, explains Martin Rademacher, Vice President Sales Oerlikon Neumag. As a pre-taste, the machine specialists from Neumünster are serving up performance figures and results from comprehensive trials conducted at their own BCF technology center as well as from two pilot systems which have been tried and tested within the market for months now.

BCF S8 performance in numbers
With up to 700 potential filaments per yarn end, the BCF S8 is raising the benchmark considerably compared to the Oerlikon Neumag S+ BCF system (400 filaments) that has dominated the global market to date. Oerlikon Neumag guarantees fine titers of up to 2.5 dpf. Furthermore, the process speed is higher than ever before – 3,700 m/min (winder speed). This permits throughputs of up to 15 percent greater compared to predecessor technologies. Overall, system efficiency is 99 percent – almost unbeatable. True to the Oerlikon Segments Manmade Fibers segment e-save philosophy, energy savings of up to 5 percent per kilogram of yarn are achievable.

BCF S8 innovations – from straight yarn paths to large cooling drums

This comprehensive progress has been achieved with numerous smart innovations. To this end, one key element above all has been optimized. The yarn path from the spinning system to the new, large cooling drum has now been almost completely straightened. This yarn path, unique to the BCF market to date, ensures that the individual filaments are subjected to minimum friction, hence once again considerably reducing yarn breaks and optimizing the overall production process. Especially noteworthy here are the, for the first time, straight yarn inlet in the texturing head – guaranteeing superior yarn quality.

And the considerably reduced distance between the heating godet duo and the texturing head also has a positive impact on the texturing process. It ensures a more even twist to the yarn and reduces the compressed air consumption. Furthermore, the texturing chambers can be removed individually, which additionally shortens servicing times. The now closed units also provide the best possible protection for the texturing jets and lamellar chambers.

The 800-mm diameter cooling drum optimally and gently cools the filaments. And this has a positive influence on the yarn quality. The new cooling drum is now equipped with a V groove for all polymers (PET, PA6 and PP) as standard.

The RoTac3 tangling unit, already established within the market, once again reduces the compressed air consumption by around 50%, while the newly-developed Witras III-37 winder achieves production process speeds of 3,700 m/min.

First intuitively-operable human-machine interface (HMI)
The new BCF S8 is the first Oerlikon Manmade Fibers segment system equipped with the innovative human-machine interface (HMI) for intelligent controlling and monitoring. In this case, the interface between man and machine has been oriented on the daily requirements of users in BCF production. With its new ‘look and feel’, it supports intuitive operation and offers direct access to important information as well as actual and target values at each take-up position by means of a touch screen. A completely new ‘alarm philosophy’ also simplifies troubleshooting and malfunction analysis. “This smart HMI system is a logical step in the digitalization of our products”, explains Dr. Friedrich Lennemann, Vice President R&D Oerlikon Neumag.
