From the Sector

Hologenix, creators of Celliant®, infrared responsive technology, and Kelheim Fibres, a world-leading manufacturer of viscose specialty fibers, have partnered to launch Celliant Viscose at ISPO Munich 2021. Celliant Viscose is a finalist in Best Products by ISPO and will be showcased in the Fibers & Insulations Category for ISPO Textrends, where realistic views and 3-D simulations will be available for each material.

The introduction of nature-based Celliant Viscose will be the first in-fiber infrared sustainable solution on the market and meets a consumer demand for more environmentally friendly textiles. An alternative to synthetic fibers and extremely versatile, Celliant Viscose blends beautifully with cotton, micromodal, lyocell, wool varieties including cashmere. It also has many applications across industries as it is ideal for performance wear, luxury loungewear, casual wear and bedding.

Celliant Viscose features natural, ethically sourced minerals embedded into plant-based fibers to create infrared products that capture and convert body heat into infrared, increasing local circulation and improved cellular oxygenation. This results in stronger performance, faster recovery and better sleep.

Celliant Viscose provides all the benefits of being a viscose fiber — lightweight, soft, highly breathable, excellent moisture management — as well as fiber enhancements from Celliant infrared technology. Celliant’s proprietary blend of natural minerals allows textiles to capture and convert body heat into full-spectrum infrared energy, resulting in stronger performance, faster recovery and better sleep. In addition, Celliant is durable and will not wash out, lasting the useful life of the product it powers.

An Affordable, Long-lasting Solution with Diverse Applications
As opposed to other IR viscose products which are coatings based, Celliant Viscose’s in-fiber solution increases wearability and longevity with a soft feel, durability from washing and longer life. The combination of Kelheim’s distinctive technology and the Celliant additives creates this unique fiber that provides full functionality without the need for any additional processing step — a new standard in the field of sustainable IR viscose fibers. This single processing also makes Celliant Viscose more cost-effective and time-efficient than coatings.

In addition, Kelheim’s flexible technology allows targeted interventions in the viscose fiber process. By modifying the fiber’s dimensions or cross sections or by incorporating additives into the fiber matrix, Kelheim can precisely define the fiber’s properties according to the specific needs of the end product.

Highly Sustainable
Celliant Viscose is a plant and mineral-based solution for brands seeking an alternative to synthetic fibers. It contains natural raw materials that are from the earth and can return safely to the earth.

Nature-based Celliant Viscose is certified by FSC® or PEFC™, which guarantees the origin in sustainably managed plantations, and is part of the CanopyStyle initiative to protect ancient and endangered forests. The production of Celliant Viscose takes place exclusively at the Kelheim facilities in Germany, complying with the country’s strict environmental laws and guaranteeing an overall eco-friendly product.

Backed by Science
Celliant is rigorously tested by a Science Advisory Board composed of experts in the fields of physics, biology, chemistry and medicine. The Science Advisory Board has overseen 10 clinical, technical and physical trials, and seven published studies that demonstrate Celliant’s effectiveness and the benefits of infrared energy.

The company, founded in 1993, has established a reputation for leadership in new printing techniques and technologies with customers across Europe, as well as with many of the leading Turkish brands.

Mission
On its mission to achieving continuous progress in error-free and resource-efficient manufacturing, İlay has just taken delivery of a new Monforts Montex stenter range, with a working width of two metres and eight TwinAir chambers.

“This installation provides us with much improved control options for all process parameters and compared to the old stenter it is replacing, we are particularly impressed with the energy savings we are making,” Mr Savaş says.

Achieving energy savings on Montex stenters has been a key focus for Monforts designers and engineers in Germany for many years.

With the TwinAir heating chamber system within a Montex stenter, top and bottom airflows can be regulated completely independently of each other, ensuring heat is only applied when and where it is required. The Optiscan balancing system ensures continuous automatic evaluation of the distance between the nozzles and the fabric for highly economical and contact-free drying.

The resulting constant evaporation rate within the stenter ensures optimum energy utilisation. In addition, TwinAir chambers feature special panelling for low heat radiation, careful sealing of all connecting positions and chamber access points, and air locks at both the entry and the exit.

“Monforts stenters set the benchmark in terms of energy efficiency and help conserve resources,” says Ahmet Kılıç, founder of Neotek, the representative for Monforts in Turkey. “Automatically setting the initial moisture content requirement for a specific process before drying to a minimum value helps reduce heat evaporation and consequently, energy consumption. The hermetic sealing of the stenter frame further prevents the loss of heated air as well as the ingress of excessive cold air – which has to be heated back up if it is not kept out in the first place.”

The new Montex line was completed at İlay Textile in August 2020, with no problems during either installation or commissioning.

Technical textiles fulfil many functions: they hold, they lift, they fixate, they stretch – and they tension. In this function narrow textiles fulfil an important task in product development. And they offer significant advantages over metal or plastic tensioning devices such as springs, clamps or cable ties.

Properties
Textiles are light: a property that plays a central role in modern mobility. Textiles are flexible: from extremely high to extremely low elasticity: the force-elongation behaviour of elasticated narrow textiles can be precisely defined. Depending on the tensioning task to be performed. Textiles tension in tight packaging spaces: elastics can also be used where space is too tight for springs and clasps. Textiles are energy efficient: lightweight, with high tensioning force. Textiles are easy to handle: replace a connector spontaneously and without tools, quickly change the length or roll up and store a supply. And textiles are sustainable: natural fibres and rubber are natural and ecologically degradable raw materials; synthetic fibres can be completely produced from recycled materials.

Applications
Development teams in numerous industries leverage these properties for their products. For example, for flexible machine parts in mechanical engineering, for switch contacts in electrical engineering, for oscillation-capable locking systems in the construction industry, for noise- and vibration-free seating systems in the automotive sector or for grip rings in the toys industry.

Tasks
Particularly en vogue today, when we are spending more time than usual in our own homes: applications for narrow textiles in the furniture industry. They go far beyond the area of legacy home textiles: as tensioning elements in armchairs, sofas and chairs, as hinge solutions in cupboards, as fixation elements in extendable or folding tables. Narrow textiles are used for gripping tasks almost everywhere in the living room.

"JUMBO-Textil specialises in precisely implementing the individual requirements for defined force-elongation values of elasticated narrow textiles: we adapt the technical properties of our products precisely to the specific task and the respective raw materials," explains Werner Thiex, Sales Director Automotive. "Precise technical specification plus sustainable raw materials – this is a crucial combination in the 21st century".

Optimum wool dyeing solution aligned to ZDHC MRSL standards

Singapore – Huntsman Textile Effects’ LANASOL® CE dyes, provide the industry with the sustainable alternative to after-chrome dyes for wool. LANASOL® CE dyes offer a consistent, safe and reliable dyeing process that can effectively replace chrome dyes for wool. This helps mills conform to ZDHC MRSL standards and meet the stringent requirements of global brands and retailers.
The use of Chrome VI, including Dichromate, is banned in the ZDHC Manufacturing Restricted Substances List (ZDHC MRSL). Wool processors working for brands and retailers that have adopted ZDHC MRSL must therefore act quickly to finalize their chrome replacement developments.

Developed by Huntsman Textile Effects specifically to meet these challenges, LANASOL® CE is a state-of-the-art chrome-free dye range that allows mills to discontinue the use of after-chrome dyes. LANASOL® CE outperforms traditional after-chrome dyes across the board – at every level of dyeing and processing.

“LANASOL® CE dyes have always been recognized as the leading brand in the wool industry. Our innovative dyeing auxiliaries and successful dyeing systems with LANASOL® CE provide the highest technical performance, helping customers to protect the natural beauty of wool, achieve water, energy and time savings while rendering chrome dyes obsolete,” said Alessandro Larghi, Global Marketing Manager for Wool at Huntsman Textile Effects.

As a champion of a sustainable textile industry, Huntsman Textile Effects has long been a strong advocate for the shift away from after-chrome dyes. Huntsman Textile Effects first introduced LANASOL® CE in 1997, before the introduction of any regulation on the restricted use of dichromate.

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

STAMFORD – German ultralight aircraft specialist Flight Design has chosen Hexcel as its key supplier adopting low-temperature curing prepreg into its aircraft production. Hexcel’s HexPly® M79 Carbon Fiber prepregs deliver a more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight Design has always relied heavily on composites for its aircrafts’ ultralight construction and turned to long-term composite materials partner Lange + Ritter, part of Hexcel’s European distribution network, when they began searching for a prepreg material solution. Hexcel and Lange + Ritter created several new product codes specifically for Flight Design and then supplied materials for initial handling trials and prototyping. Hexcel’s HexPly M79 low temperature curing out of autoclave solution was first used in the new F2 prototype. As part of its material supply package, Lange + Ritter also sent a team for on-site training and technical support, allowing the Flight Design production team to get up to speed with prepreg as quickly as possible.

HexPly M79 prepregs can be cured at temperatures as low as 70˚C for eight hours or 80˚C for four hours, reducing tooling costs and increasing build rates. When combined with Hexcel’s innovative air venting Grid Technology, HexPly M79 UD carbon tapes can also be laminated with reduced debulking steps to produce void contents <1% irrespective of laminate thickness. With consistently low void contents and improved mechanical properties, designers and engineers are able to further optimize highly loaded composite aerostructures.

As more and more of its composite aircraft parts are transferred to prepreg technology, Flight Design is seeing the benefits of its switch to HexPly M79. Lay-up is cleaner and more precise, low temperature oven curing is quick and energy efficient, and the manufacturing process consistently outputs exceptionally high-quality laminates and components. The long-term strategy is to integrate HexPly M79 across the range, with Hexcel materials lightening the ultralight aircraft at Flight Design even further.

“The materials and technology package from Hexcel and Lange + Ritter has been a big success for us at Flight Design,” comments Daniel Gunther, Managing Director at Flight Design. “When we took the decision to switch to prepreg, we looked at many options but only Hexcel and Lange + Ritter could offer us low temperature out-of-autoclave (OOA) curing, globally respected material quality and the customer service levels we were searching for.”

Non-contact precision spray technology enhances productivity, sustainability and process control

Baldwin Technology Company Inc. has announced that it will showcase the TexCoat G4 non-contact precision spray fabric finishing system at the Techtextil North America tradeshow, held from May 12 to 14, 2020, in Atlanta (booth #3048).

With extensive sustainability benefits, unprecedented tracking and process control, and industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, as well as minimal water and energy consumption. 

Baldwin’s innovative non-contact spray technology eliminates chemistry dilution in wet-on-wet processes. The TexCoat G4 consistently and uniformly sprays chemistry across the fabric surface and applies it only where needed, on one or both sides of the fabric. Customers can expect no bath contamination during the finishing process, as well as minimal downtime during changeovers, which are made easy with recipe management that includes automated chemistry and coverage selection.

The TexCoat G4 also enhances sustainability by wasting no chemistry during color, fabric or chemistry changeovers, and because only the required chemistry volume is applied to the fabric, wet pick-up levels can be reduced by up to 50 percent—leading to 50 percent less water and energy consumption. Furthermore, in single-side applications, drying steps can be eliminated for various textiles, including those that are back-coated and laminated, thereby streamlining and simplifying the production process.
