From the Sector

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

Ansmann AG hat eine neuartige, überhitzungssichere Heizfolie auf der COMPAMED 2022 in Düsseldorf vorgestellt. Diese erste drahtlose Heizfolie mit völlig konstanter Wärmeverteilung war, der medizintechnischen Veranstaltung entsprechend, zu einem beheizbaren Rollstuhlpolster verarbeitet. Doch auch eine Vielzahl weiterer Anwendungen sind mit der Kunststofffolie umsetzbar: Beispiele sind beheizbare Fahrradsättel, Smart Clothing, oder sonstige wärmende Flächen und Elemente in Automotive oder E-Mobility Anwendungen vom Autositz bis zur beheizten Lastenradkabine.

Im Unterschied zu bisherigen Heizlösungen kann sie in eine beliebige Form zugeschnitten und auch geknickt oder gefaltet werden. Zudem kann sie aufgrund ihrer Materialeigenschaften nicht überhitzen. Die Wärmeverteilung in der Fläche ist dabei völlig gleichmäßig und dadurch sehr angenehm für den Nutzer.

Jedes Produkt mit bis zu 1×1m großer Fläche in beliebiger Form, kann an eine Niedervolt-Stromversorgung angeschlossen werden und für gleichmäßige Wärme mit einer solchen Heizfolie bestückt werden.

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.

HEATHCOAT FABRICS partnered again with BRÜCKNER Textile Technologies and their sales partner ADVANCED DYEING SOLUTIONS to install a finishing line for industrial textiles. HEATHCOAT FABRICS specializes in the production of technical textiles in the fields of texturising, weaving and warp knitting as well as dyeing and finishing. The prroducts are manufactured for use in the automotive, healthcare, defence, and aerospace industries

Mrs. Regina Brückner, CEO and owner of the BRÜCKNER Group stated: "To meet the complex re-quirements of HEATHCOAT is not easy because of the great variety of technical textiles produced. Our line has to finish light as well as heavy articles, so the design, control and the whole line layout have to be flexible, functional and still easy to operate. Fortunately, the team at HEATHCOAT FABRICS is very innovative and open-minded, and together we worked hard to develop the right technology and han-dling. We are very happy that we could convince this customer, whom we appreciate very much, with the productivity of our line and of course with our technological know-how."

The direct gas heated BRÜCKNER POWER-FRAME stenter with its staggered heating source arrangement every half zone provides best available temperature consistency across the length and the width of the stenter. The unit is equipped with a low-lub, horizontally returning combined pin / clip chain and several fabric paths, especially designed for the different fabrics being processed. Together with HEATHCOAT FABRICS technologists, the BRÜCKNER design team developed a special delivery end of the stenter with different edge trimming and slitting possibilities. Depending on the kind of products, the fabrics can be batched on large diameter A-frames, wound on cardboard tubes or plaited into trolleys.

Monforts will highlight its technologies for special technical textile applications at this year’s ITMA ASIA + CITME which takes place at the National Exhibition and Convention Center in Shanghai, China, from November 20-24.

One of Monforts' developments is the Montex 8500 XXL stenter system for the production of technical fabrics in widths of up to 6.8 metres. Among the products made on this system are treated nonwovens for the geotextiles and filter media markets, tarpaulins, advertising banners, black-out curtains, membranes and many more.

On Montex©Coat coating lines, meanwhile, the possibilities range from the single-sided application of finishing agents for outdoor clothing and adding functionality to home textiles, to the creation of materials for sophisticated lightweight construction and automotive and aerospace components.

“Many more applications are possible, such as the overdyeing of denim, the creation of double-face coated materials, fabrics awnings, tents and medical drapes and the pre-treatment of substrates for digital printing”, explains Gunnar Meyer, Monforts area sales manager for China. “A range of different doctor blades and their combinations can be supplied to meet individual requirements, including air knife, roller knife, foam, screen and magnetic roller coating. The latter option is recommended for lines with working widths of over 2.4 metres.”

In addition, Monforts can provide the necessary explosion-proof ranges for solvent-based coatings and high temperature processes up to 320°C, such as the PTFE coating of nonwoven filter material. These lines are equipped with special burners, stenter chains, and insulation.

With over 60 participants from Europe and Turkey, the first SMCCreate Design Conference took place in Antwerp from 28-29 June. The conference was jointly organised by AVK – Federation of Reinforced Plastics and the European Allicance for SMC BMC. The topics covered the wide spectrum of SMC and BMC manufacturing, from design to sustainability solutions. 16 speakers from different European countries showed what is important in component manufacturing and design, and which solutions the companies offer in regard to materials, performance and much more.

After an overview of the general market developments and how the economic requirements affect component manufacturing, the focus was on the possibilities to enable sustainable design with SMC/BMC. In the second conference section „part design“, the topics of design and modelling, design with structural analysis and flow simulation, standards, and best class solutions as well as surface modification were presented.

A rather newer field was highlighted on Day 2 with Carbon SMC, discussing mobility and automotive applications. These included the integration of multiple material technologies, not forgetting the possibility of implementing green deal strategies here too. The advantages of SMC in automotive components for electrification were explained in more detail. The conference concluded with a sporty presentation on the development of a carbon SMC rear frame for a downhill mountain bike.

International technology group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at Techtextil in Frankfurt from June 21 to 24. The ANDRITZ product portfolio covers state-of-the-art nonwovens and textile production technologies, such as air-through bonding, airlay, needlepunch, spunlace, spunbond, wetlaid/WetlaceTM, converting, textile finishing, recycling, and natural fiber processing. For Techtextil, special focus lies on technologies for textile recycling, needlepunch, airlay, wetlaid glass fibers and textile calendering.

TEXTILE RECYCLING TECHNOLOGIES BASED ON TEARING
With the acquisition of ANDRITZ Laroche SAS, ANDRITZ has expanded its product portfolio to include airlay and recycling technology as well as bast fiber processing technologies. Complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end-uses are one focus of this product range. Customer awareness and regulations are forcing clothing brands to recycle their textile waste in their own products. Recycled fibers can also be used in the nonwovens industry for various applications, for example in the automotive industry, for insulation, mattresses, and furniture felts.

ANDRITZ Laroche offers a complete process range of tearing lines from 50 up to 3,000 kg/h, which can be used for almost all types of pre/post-consumer textile waste. The aim is to preserve the character of the original fibers, for example cotton, by maximizing fiber length, strength and feel.

With global consumers becoming more conscious about personal hygiene and environmental protection, exhibitors at Cinte Techtexil China will spotlight materials and technologies for products that respond to these trends. The fair will probe into the associated growth opportunities as the country is one of the leading markets for nonwovens and technical textiles. The event will be held from 6 – 8 September at the Shanghai New International Expo Centre.

The technical textiles and nonwovens industries, the latter notably, are significantly expanding amid the pandemic. A recent forecast[1] predicts that the global polypropylene nonwoven fabric market will continue to rise at a CAGR of 6.7%, reaching USD 39.23 billion by 2028. The anticipated growth is bolstered by demands in end-use industries such as sanitation, medical, automotive and more. In 2020, Asia Pacific was named the largest regional market in the world and is expected to grow significantly over the forecasted period.

The prediction reaffirms the growth prospects of nonwovens. In this regard, industry players expressed much optimism about associated future opportunities during Cinte Techtextil China last year. “The field of nonwovens is poised for a positive growth as the awareness of personal hygiene and pandemic prevention sustains in the domestic market,” commented Mr James Gao, Head of Marketing and Textile Technologies, Uster Technologies (China) Co Ltd. He added: “We decided to join the fair and showcase our new launches as we remain confident in the future development of the industry, especially since China is dominating the global scene.”

Going green is the way forward
Turning to yarns and fibres, the sector is shifting to greener and smarter production that echoes the trend towards sustainability that is gaining considerable traction across the globe. Meanwhile in China, this movement was observed by many exhibitors at the 2021 edition, including Mr Roberto Galante, Plant Manager of FMMG Technical Textiles (Suzhou) Co Ltd, the Chinese subsidiary of the Fil Man Made Group. He mentioned: “The market is paying more attention to environmental protection, and we receive enquiries about special yarns for this every day. We focus on technical yarns for filtration as well as anti-bacterial properties, which are very important for the environment. The potential here in China is incredible and this is a big opportunity for everybody.”

Cinte Techtextil China’s product categories cover 12 application areas, which comprehensively span across a full range of potential uses in modern technical textiles and nonwovens. These categories also cover the entire industry, from upstream technology and raw material providers to finished fabrics, chemicals and other solutions. This scope of product groups and application areas ensures that the fair is an effective business platform for the entire industry.

The Saxon Textile Research Institute (STFI) will be presenting innovative highlights from research and development at Techtextil 2022, the international trade fair for technical textiles and nonwovens. In addition to a warp-knitted textile façade greening in a modular system and textile lightweight construction elements for the building sector made from hemp as a renewable raw material, the STFI will also be showing innovations from nonwovens research. The project optiformTEX is an example of the nonwovens competence: in this project, the mass per unit area was specifically influenced for the production of semi-finished products in the automotive sector. Furthermore, the Chemnitz Institute exhibits an ecological foam coating for protective textiles. Central highlight of the STFI's presence at the fair is also a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel.

Highlights at Techtextil 2022
The greened façade tile is a system with which large building surfaces can be cost-effectively greened through a simple, modular segment structure. In addition to insulating the building, the system has been created to meet the design requirements of a modern city centre; low-maintenance greening is made possible through functional integration in the textile carrier layer and coordinated plant selection.

Moulded components made of natural fibre nonwovens are increasingly used in the automotive sector. Conventional nonwovens currently have uniform masses per unit area. Technical solutions for load-oriented component reinforcement and the resulting optimised use of materials represent an enormous economic potential. The basic idea of “optiformTEX” was therefore to specifically influence the mass per unit area distribution in the pile before the semi-finished product is consolidated. As a result, a textile-technological process and the corresponding plant component were successfully developed.

Future-oriented materials are offered by developments from the field of renewable raw materials in combination with bio-based resin systems: In the “Gro-Coce” project, an innovative ceiling system was developed by combining sustainable building products and methods. Currently, a high-performance hemp-based semi-finished product as well as the steps for its reproducible production by means of textile surface formation is developed by the research team. Initial application and load tests of the hemp-based semi-finished products on wooden beams confirmed the high performance potential of the natural fibre materials.

Special functional textiles are based on composite materials with coatings or membranes. The previous production of the coatings/membranes poses ecological and health risks. At STFI, solvent-free, purely aqueous coating systems and a technology for their application were therefore developed for the protective textile sector, resulting in a breathable, waterproof and wash-resistant textile coating.

The central highlight of the STFI's presence at the fair is a mobile robot system, which demonstrates the automated loading of a small-scale bobbin creel. At the STFI, the robot is part of the “textile factory of the future”, where a play mat is woven and processed step by step along the textile chain.

The Techtextil and Heimtextil Summer Special exhibitions, taking place together in Frankfurt from June 21-24, represent an opportunity for Monforts to showcase its finishing and coating technologies for two of its major markets – especially at a time when energy prices continue to soar for textile manufacturers in Europe.

Existing customers of Monforts include many manufacturers in the field of home textiles, as well as those making geotextiles, automotive fabrics and other functional materials – all of whom will be well represented in Frankfurt this June. Dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics, as well as high-temperature filter materials.

Energy prices are rising steeply everywhere and a particular emphasis for Monforts in Frankfurt will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as better insulation of the treatment chambers or the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air resulting in a radical reduction in the conventional heat supply required compared to gas and thermal oil heating. The modular system for heat recovery can also be extended for exhaust air cleaning and odour elimination. Monforts can provide a range of further resource-saving and energy recovery options tailored to each individual line installation including modification of the heating source.

With the Qualitex 800 visualization software, 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.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

All of these very different materials require coating and finishing for maximum efficiency, using Monforts technologies which provide 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.

The Monforts EcoApplicator offers further potential for sustainably achieving perfect finishes via a precise direct application system, as an alternative to conventional padding – where fabrics are immersed in a bath of the required finishing chemicals. It can significantly further reduce the energy and water required and finishes can be applied on just one side of the fabric, or both, and even separately on each side, to be sealed in place via different heating zones in the stenter.
