From the Sector

In China, the textile industry is forward-looking and resilient – with a healthy appetite for new technologies and a determination to keep its leading position. Sustainability is increasingly coming into focus, so there is a growing demand for recycling technologies, as well as automated solutions and digitalization. Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association, is clear: “China is the main market for a large number of our association members.” On top of growing consumer demand and technological capabilities, the latest ambitious five-year plan will drive further development of the Chinese textile industry in world markets, and Swiss companies will work with all stakeholders to enable its success.

Market proximity
Swiss companies realized many years ago that geographical proximity is the key to success. Stäubli has started to set up offices in Chinese cities since 1998 and counts 12 locations today, to serve the whole country. In 2002, Itema established a centralized local branch which today has 160 employees in various functions. Loepfe has expanded its presence by creating an independent local business unit to overcome the 9,000 km distance by air, while Uster Technologies has had a Chinese subsidiary since 1982, with offices and service stations in different provinces. Luwa set up its offices and workshop in Shanghai in 1997. Rieter established a presence in mainland China in 2005, driven by a strong commitment to expanding the country’s know-how and expertise – and ten years later opened an advanced research center. All Swiss companies with serious business goals in China have made similar commitments to connect with customers and maintain strong relationships.

Understanding Chinese customers
Swiss companies also understand that Chinese customers require dedicated attention, and that speed is more essential than ever in delivering both machines and services.
Manufacturers in China are seeking cost-effective solutions to remain competitive, while consumers are looking for value in their purchases. Companies need to develop solutions that provide tangible economic benefits to their clients. Furthermore, energy savings have become paramount in China, due to the government's commitment to environmental sustainability and reduced carbon emissions. “Businesses are adopting more energy-efficient processes and technologies to meet stringent energy conservation and emission reduction targets,” says Peter Schnickmann, Managing Director at Luwa Air Engineering (Shanghai). He notes an investment trend for solutions helping Chinese companies cut operational costs and minimize their carbon footprint.

To enhance the reputation of both companies and products – and boost the image of the entire industry – the environmental impact needs to decrease. Priorities are saving water and waste, as well as reducing, replacing or completely eliminating the use of harmful substances. China has a strong demand for environmental-friendly solutions and sustainable technologies.

Customer-oriented in weaving
The huge number of Chinese fabric producers calls for an immense volume of weaving machinery to be supplied by international and local providers. Swiss machinery manufacturers hold an impressive share of this business.
Chinese weavers require advanced technology, with increasingly higher standards of efficiency. In weaving preparation, latest solutions match the speed, quality and reliability now wanted. Weaving machines too offer the eco-efficiency, performance, and ease of use needed, with innovations that extend the scope of sustainable weaving, and open-platform systems configurable to weavers’ specific operations. A huge increase in demand for technical textiles in recent years has been driven by applications such as carbon fiber, aramid and glass fiber.

Profitable in spinning
China’s competitive advantages come from its large-scale and integrated manufacturing capabilities, along with the use of advanced automation and digitization technologies. Spinners aim to capitalize on extended market opportunities, with more economical production. The latest air-jet spinning machines serve these goals, allowing exceptionally low production costs per kilogram of yarn, coupled with high flexibility and reliability. Sustainable yarns are in great demand.

The automation trend in spinning mills focuses on connecting production processes. Data is used to ensure the highest quality standards, most efficient raw material usage, reduction of waste, and energy savings. To make spinning mills more competitive, latest solutions combine cutting-edge hardware, data-enabled software and renowned textile expertise.

Fibre Extrusion Technology Ltd (FET) of Leeds, UK is celebrating a year of achievements since its new Fibre Development Centre was first opened. This period has shown a marked acceleration in the number of client technical trials conducted, involving the ever-increasing development of new polymers.

FET designs, develops and manufactures extrusion equipment for a range of high value textile material applications worldwide, offering melt spinning, wet spinning and spunbond/meltblown options. Since its inception in 1997, a major part of FET’s service portfolio has always been to collaborate with industrial and research establishments in testing, evaluating and developing high value materials with diverse, functional properties. FET’s previous Process Development Laboratory presided over the development of about 60 new polymer types in multifilament, monofilament and nonwoven formats.

Since the new Fibre Development Centre came on stream, this process has accelerated and the number of new polymers has now increased to over 70, with considerably enhanced facilities more than doubling capacity and increasing efficiency. Clients frequently spend several days on site participating in development trials and technical sales meetings, so the new Centre is designed to make their stay even more efficient and comfortable.

With more new trials booked for the rest of the year and well into 2024, it is expected that many more new polymers will be developed, with sustainable fibres leading the way.

Carbios inaugurated its textile preparation line at its demonstration plant in Clermont-Ferrand, in the presence of Mr. Lescure, French Minister for Industry. To streamline the textile preparation phase, which is currently carried out by hand or on several lines, Carbios has developed a fully integrated and automated line that transforms textile waste from used garments or cutting scraps into raw material suitable for depolymerization with its enzymatic biorecycling process. This patented line integrates all preparation stages (shredding and extraction of hard points such as buttons or fasteners), and provides Carbios with a high-performance, scalable development tool. The platform will help validate the biorecycling technology for textiles at demonstration plant scale (by 2024), and provides Carbios with expertise in working with collection and sorting operators to specify the quality of textiles and the preparation steps needed to make them suitable for enzymatic recycling. This expertise will also be invaluable to brands in the eco-design of their products.

Current collection, sorting and preparation infrastructures limit the amount of textile waste available for “fiber-to-fiber” recycling. Collection rates average around 15-25% worldwide^[1], and much of the waste collected is exported to Africa, Asia or Latin America for sorting.

Moreover, textiles are highly complex materials, with yarns of different composition (or nature) that are difficult, if not impossible, to physically separate. However, the highly selective enzyme developed by Carbios can specifically depolymerize the PET (polyester) present in textile material.

At present, textiles are sorted and prepared mainly by hand, with low yields, particularly for disruptors to recycling processes such as “hard points” (zips, buttons, etc.). To optimize this crucial phase, Carbios is contributing a textile preparation solution to accelerate the development of biorecycling in the textile industry. Enzymatic recycling, or biorecycling, therefore contributes to the construction of a textile recycling chain and the acceleration of textile circularity, also enabling brands to do away with used bottles.

International technology group ANDRITZ has successfully started up the new carding machine and opening/blending line it delivered to Albis in Roasio, Vercelli, Italy.

With its large working width of 5.10 meters, the machine allows for the production of nonwoven fabrics tailored to specific customer requirements while maintaining excellent properties and consistent quality. One example is Albis Curacell ®, a multilayer composite nonwoven fabric in a weight range between 35 and 70 gsm that is produced with a fully water-free patented process and is able to absorb liquid flows of over seven times its own weight. The production line also includes an advanced upstream opening and blending system from ANDRITZ.

Albis, a privately owned group founded in Italy in 1995 by Gianni Boscolo, has been a major player in the nonwoven market for over three decades. Through continuous research and development, the company offers innovative, high-quality nonwoven solutions across various sectors, including hygiene, medical, personal care, textiles, filtration, and agriculture.

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.

At this year’s Techtextil India, the Polymer Processing Solutions Division of the Swiss Oerlikon group will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Between September 9 and 12, the discussions at Jio World Convention Centre (JWCC), Mumbai, will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
The yarns used in airbags are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technol-ogies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants - without any loss of function in any climate and for the lifetime of the vehicle

Buckle up!
Seat belts have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments. “With our unique, patented Single Filament Layer Technology, we offer a sophisticated and simultaneously gentle high-tenacity (HT) yarn process for manufacturing these lifesavers and other applications made from industrial yarn”, explains André Wissenberg, Head of Marketing.

Road reinforcement using geotextiles
Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demand-ing tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC –  quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

TRÜTZSCHLER Spinning presents an innovation for the textile machinery market: the high-performance comber TCO 21XL with 12 combing heads. For many decades, eight combing heads has been considered state-of-the-art in the spinning industry. Now, Trützschler’s advanced technology and engineering proves that it is possible to build a heavy-duty comber that maximizes productivity by 50 % and saves space without compromising on quality.

They say two heads are better than one, so just imagine what 12 heads can do! That’s the simple but effective idea behind the TCO 21XL. Increasing the number of combing heads by 50 % makes it possible to increase productivity by 50 %, enabling rates of up to 150 kg/h. As a result, two TCO 21XL combers offer the same production capacity as three conventional combers. And that means companies that buy and operate two machines instead of three can achieve significant benefits in terms of their price-performance-ratio (cost/kg). The costs of running the machines are broken down into 12 instead of eight heads, making the machine more cost-effective over its entire operating life.

50 % higher productivity is great – and it can be even greater if the machine is operated with JUMBO cans. The can changer needs to keep up with the extra performance, and JUMBO cans can easily collect the additional output of the TCO 21XL because they feature a 1200 mm diameter. This makes it possible to minimize non-productive time when changing cans. Anybody who is planning a new spinning mill knows that every square meter of space adds to the overall costs. The new TCO 21XL comber offers huge benefits in this regard because 25 % less floor space is required to operate same number of combing heads. This reduces the initial building costs, while also decreasing operating costs related to lighting, air conditioning and other overheads.

UK’s Optima 3D is delivering its weaving technology to the USA, for installation at the University of Maine’s Advanced Structures and Composites Center (ASCC).

The 3D weaving system consists of an Optima 3D Series 600 shuttle weaving machine with an integrated 2,688-hook Stäubli SX jacquard and harness. It is also complemented by Optima’s compact warp delivery creel and an associated pirn winder for shuttle bobbins and a spool winder for creel spools.

Optima’s looms offer many advanced features over conventional weaving machines, particularly in terms of versatility, as a result of the comprehensive use of digital control systems allowing rapid parameter and sequence changes, coupled with an innovative shuttle system.

The ASCC is certainly no stranger to advanced technology, or indeed ambitious composite projects – in 2019 it received no less than three Guinness World Records, for the world’s largest prototype polymer 3D printer, the largest solid 3D-printed object, and the largest 3D-printed boat. In its latest project it has further introduced BioHome3D – the first 3D-printed house made entirely with bio-based materials developed in a partnership with Oak Ridge National Laboratory. The 182-square-metre prototype features 3D-printed floors, walls and roof which are fully recyclable and highly insulated with 100% wood insulation and customisable R-values. Construction waste was nearly eliminated due to the precision of the printing process.

The KARL MAYER GROUP and the Südwolle Group have joined forces in a project to explore the possibilities of merino wool for warp knitting technology. The project was triggered by the increasing demand for textiles made from sustainable and environmentally friendly materials. The cooperation was to develop innovative fabrics from renewable raw materials for use in underwear and functional sportswear. The focus of the work was on the use of wool as a material with excellent comfort properties and the look and feel of lightweight single jersey goods. The natural fiber fabric qualities are not typical for warp knitting processing, so the challenges during the project work were diverse.

Merino wool yarns with good running properties
Regarding the choice of material, the product development team of Südwolle Group recommended the Hidalgo yarn from their product portfolio. The yarn was created using the in-house developed Betaspun technology, in which a filament was twisted around a merino core. When natural fibres such as wool, cotton or silk are combined with sustainable fibres such as biodegradable polyamide as the filament, the spinning process can create durable, lightweight yarns that disintegrate completely without residue after use. The yarns made from the two components also have good running properties for use in warp knitting. "The polyamide content of the yarn increases its tenacity, reduces hairiness and makes it an excellent choice for warp knitting technology," confirmed Gabriela Schellner from KARL MAYER's Textile Product Development Department.

Shape stability paired with single jersey "look and feel"
The Hidalgo yarn, which is made from merino wool, was processed on a warp knitting machine using a carefully thought-out lapping selection to produce a light, soft fabric which, above all, retains its shape. The textile specialists at KARL MAYER had experimented with two different single bar fabric qualities beforehand and had thus adopted a new approach for jersey machines.

The first results are promising. Now more trials are needed to perfect the technique. Development partners are needed, including fabric producers, brands, and garment manufacturers, with whom the fabric qualities, machine equipment and orientation to the end applications can be refined. The KARL MAYER GROUP and the Südwolle Group are also unanimous in their desire to push the boundaries of what is possible with merino wool and knitting technology and to develop new solutions for the textile industry through further project work.

In the printing industry, direct-to-film technology is having a transformative impact on the apparel decoration space. It provides a simple and affordable garment printing process that facilitates vibrant, dynamic, full-colour designs with a durable print. It opens up opportunities for digital print service providers (PSPs) to expand their product offerings in the textile industry, their network of potential customers and expand the range of fabrics they can print on.

Direct-to-film vs. Screen Printing
Direct-to-film printing is the process of digitally printing directly onto a special transfer film sheet. The printed film is subsequently sprinkled with a hot-melt powder and heated. Once the transfer sheet is cured and dried, it can be heat-pressed onto a variety of fabrics to create premium transferred designs for customised merchandising, sportswear, and an array of other promotional applications for the textile market. Compared with traditional screen printing, the plate creation required for that process is far too time-consuming. Not only this, but it does not match direct-to-film’s ability to produce vivid colours and quality details such as shapes, lettering, and motifs often sought after in the promotional and merchandising space for bespoke textiles.

The Mimaki TxF150-75
Mimaki’s first direct-to-film inkjet printer is the TxF150-75, a fitting extension to the 150 series, with a maximum printing width of 80cm. Offering a stable printing plotter, the model’s built-in ink circulation system and degassed ink pack are resolutions to common direct-to-film challenges such as poor ink ejection and white ink clogging. The new printer also includes core Mimaki features including NCU (Nozzle Check Unit) and NRS (Nozzle Recovery System) for stable, uninterrupted print production. Operating in harmony with the textile printer itself is Mimaki’s ECO PASSPORT by OEKO-TEX® certified water-based pigment textile inks, formulated especially for the TxF150-75. Coupled with Mimaki’s RasterLink7 RIP software, users are offered end-to-end oversight and efficiency from creative design to final product.

In addition, and in line with Mimaki’s collaborative approach to meeting customer needs, Adkins has developed an 80cm wide powder shaker cure unit to complete this ‘A brand’ direct-to-film printing solution. By offering the printer and post-processing unit at 80cm wide, customers can print larger garments with less waste and quicker production times, making the process much more cost effective.
