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.

Pulcra Chemicals and Inditex develop Sustineri Coloring, a combined pretreatment and dyeing process for cotton and polyester/cotton resulting in water, time and energy savings. This process is the result of a joint research between Pulcra Chemicals and Inditex with the goal to mitigate the impact of standard dyeing processes and to reduce the use of natural resources.

Sustineri Coloring is based on newly engineered process chemicals which allow a one bath pretreatment and dyeing process for dark, medium and light shades of cotton and polyester/cotton fabrics by exhaust method. This results in shorter processing time and less use of water and energy.

The process is already used by selected mills and it showed that Sustineri Coloring is reducing in pretreatment and dyeing the processing time by up to 60 % and the water and energy consumption by up to 80 and 60% respectively. The state-of-the-art products allow a one bath treatment which is the key in saving resources.

Freudenberg Performance Materials Apparel (Freudenberg) launches its biodegradable fusible cotton shirt interlinings range 46xx. With this innovation, the world’s leading specialist in woven, knitted, weft and nonwoven interlinings reduces its impact on the environment and supports customers in achieving their own sustainability objectives. In Asia, the series is marketed under the name 42xx series.

Approved biodegradability and non-toxicity by Hohenstein Laboratories
The new Freudenberg fusible interlinings for shirts and blouses have been developed in such a way that they are harmless to people and the environment at the end of their life cycle. Germany’s independent Hohenstein Laboratories performed biodegradation tests on the 46xx series, based on the Hohenstein method which draws on DIN EN ISO 11721-2:2003 and EN ISO 846, and approved it as biodegradable and ecotoxicologically harmless. The tests by Hohenstein showed no negative effects on either the germination of garden cress nor on earthworms in the acute toxicity test.

Energy-saving interlining
The new biodegradable shirt interlinings also show great potential for energy saving, as the fusing can be performed at a low temperature. Concretely, this means that the resulting temperature between the upper fabric and the shirt interlining during fusing is only 127°C which is significantly lower than the commonly used temperature of 143°C. Certified to OEKO-TEX® STANDARD 100 Class II for successfully testing for no harmful substances, the shirt interlinings are washable at up to 40°C and resistant to dry cleaning. In addition, it has also passed all ecological-toxicological tests and is a perfect end-of-life cycle solution.

Product details and availability
The products in range 46xx are available in Europe in the color white and the following weight classes: 4605 (90g/m2), 4616 (150g/m2) and 4618 (55g/m2). The adhesive of the interlinings consists of a 100% degradable bio-polymer. The shirt interlinings are ideal for reinforcing shirt and blouse collars, cuffs and plackets used in fashion, leisure and business clothing. The biodegradable, non-toxic interlinings are particularly important for labels with an ecologically sustainable claim.

Within its TEXTILE SOLUTIONS, the CHT Group has developed solution approaches for manufacturing companies in the textile value chain that have to use a lot of energy for their production. This is intended to compensate high energy costs and make a positive contribution to climate protection.Application specialists work with customers to develop individual savings potentials that are specifically tailored to the production facilities and requirements. Thus, depending on the process, fabric and machine, energy savings of up to 30% can be achieved with the use of innovative CHT textile auxiliaries, dyes/pigments and the corresponding process optimisations. In addition, the numerous concepts and optimally matched products can minimise water consumption or shorten the process time.

Energy-efficient cold bleaching instead of pad-steam bleaching processes in continuous pretreatment and the 4SUCCESS process for energy-efficient and resource-saving pretreatment and dyeing of cotton help to save energy. Likewise, the use of polymer binders, which do not require energy-intensive fixation, saves energy.

Efficient pretreatment with the new polymer technology CPT (Comb Polymer Technology) achieves good cleaning effects even with low liquor ratios and thus less water to heat up. To save costs for energy-consuming heating, there is also the gentle low-temperature fixation in the easy care finishing. The OrganIQ EMS Jeans system enables jeans finishing with a reduced application temperature compared to standard processes.

With TIME BOOST, a process for fast polyester dyeing processes, not only significant energy but also time savings are achieved by omitting pre-washing and by shortening heating and migration times. SHORT CUT also leads to shorter process times when dyeing polyamide.

To avoid cost-intensive intermediate drying, the CHT Group offers the SCREEN-2-SCREEN with PRINTPERFEKT S2S which facilitates printing in a wet-on-wet technology.

In addition to numerous other products, the CHT Group also offers its customers digital tools to optimally support process optimizations. The "BEZAKTIV Soaping Advisor" calculation program within the CHT Textile Dyes app can be used to evaluate and improve dyeing and soaping processes in a simple and target-oriented way.

• 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.

The Turkish company ARIKAN Mensucat Industry and Trade Inc. was founded in 1993 and is located in Kahramanmaraş, one of the southernmost cities of the country. Today, the family-owned company employs around 1,500 people and finishes around 55 tons of knitwear every day. In addition to many well-known Turkish fashion manufacturers, ARIKAN also supplies international manufacturers in Europe, Russia, the Gulf States and other leading international markets.

The German machinery manufacturer BRÜCKNER supported the Turkish company from the very beginning. From the foundation of the dyeing and finishing plant, BRÜCKNER supplied three stenters for the finishing of the high-quality knitted fabric in 2014. Two more lines followed in 2016. For decades, BRÜCKNER has been the market leader for the finishing of knitted fabric. Especially for very fine and elastic fabric, special line configurations and technological know-how are necessary to be able to produce a high-quality end product. During the drying and heat-setting process, for example, extremely accurate and uniform temperature distribution over the entire length and width of the dryer is essential. In the BRÜCKNER stenter this is achieved, among other things, by the alternating arrangement of the thermal zones every 1.5 meters and by the proven split-flow air system.

The machine operators at ARIKAN appreciate the easy control of BRÜCKNER lines. The visualization is intuitively designed and offers many auxiliary systems for an optimized production process. In addition, significant energy savings can be achieved with just a few changes to the machine parameters.

The management at ARIKAN attaches great importance to energy saving, especially in the fabric finishing department. The drying process is one of the most energy-intensive in the entire process chain, therefore the biggest savings can be made here. These have a direct impact on the manufacturing costs of the textiles and thus on competitiveness in the market. In the meantime, talks are already in progress for another BRÜCKNER line which will include a very special feature: a combined heating system for the dryer. For many customers - and so also for ARIKAN in Turkey - e.g. steam energy is available free or very cheap. With the combined heating system developed by BRÜCKNER it is possible to use this steam energy for heating up the dryer and thus to achieve significant savings. If the available steam is not sufficient for a running process, it is automatically switched over to gas heating. This mode of operation does not only have an effect on the energy costs, but also makes a considerable contribution to environmental protection.
