The new Orthopac RXVMC-20 automatic straightening system for forward control of knitwear with strong distortions can remove distortions in textile webs even faster and more precisely.

"With the new straightening concept, special attention was paid to the straightening mechanics and their interaction with the analysis electronics of the scanner system," explains Head of Sales Thomas Höpfl. Two individually controlled and driven straightening modules with a total of four bow and three skew rollers ensure that the correction of bow and skew distortions takes place in small steps. The control concept is also new. A scanner group at the infeed of the straightening machine detects distortions even before they reach the correction rollers. This way, the rollers are brought directly into position and the fabric is corrected from the very first centimetre. A scanner group at the outlet also detects possible residual distortion, which is corrected at the second straightening module. This enables an even more precise and faster response when it comes to reacting to rapidly changing distortions.

The Orthopac RXVMC therefore shows its full strength when straightening knitwear and distortion-sensitive fabrics. Knitted fabrics are special in terms of distortion dynamics. It is difficult for operators when changing the fabric rolls to join the relatively short fabric webs with weft and loop-straight seams. Before and after unavoidable insufficient seams, the distortion (e.g. right before to left before) changes abruptly. Conventionally, the distortion change is only detected by scanning at the output of the straightener.
 
The RXVMC concept enables a shortened reaction time to jumping distortion, (especially in the case of seams) due to the improved scanning concept with scanning at the outlet and inlet. This reduces knitted fabric outside the straightening tolerance up to 50 percent after each seam. Fewer fabric pieces have to be reprocessed. It guarantees higher quality goods and thus less waste.

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.

The German companies Brückner, Groz-Beckert, the Karl Mayer Group and Thies invite representatives of the Indian textile industry to a symposium with presentations and discussion panels in Surat, India, on October 11 and 12, 2023. The event will be held at the Marriott Hotel Surat and will focus on the current demand trend for warp knitted elastic fabrics.

The demand for warp knitted elastic fabrics has increased rapidly in the past two to three years. On the one hand, this offers the Indian textile industry new growth opportunities and the chance to establish itself in a leading position in the growing market. On the other hand, the turnaround also holds challenges as the production steps involved in manufacture of warp knitted elastic fabrics are strikingly different from the conventional methods.

In order to provide the Indian warp knitting industry with optimum support in this change, Brückner, Groz-Beckert, Karl Mayer and Thies are inviting participants to a specialist symposium on the subject of "Production of Warp Knitted Elastic Fabric". Industry experts, stakeholders and textile visionaries are invited to share their insights and experiences with the guests.

The aim of the symposium is to provide a platform where knowledge can be exchanged and cooperation intensified. The symposium offers a wide variety of technical presentations as well as best practice examples and showcases technologies and innovations in warp knitting technology.

Those interested in attending the symposium may contact Vinod Kumar (Brückner & Thies), Dipak Panhalkar (Groz-Beckert) or Apurva Jariwala (Karl Mayer) to register.

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.

The EU's planned ban on the entire group of per- and polyfluoroalkyl substances (PFAS) would endanger many industrial processes, states VDMA Textile Machinery. Textile manufacturing would be affected twice – by missing important chemicals for technical textile production and by the lack of indispensable textile machine components. The latter would affect the whole supply chain from textile machinery manufacturers and its suppliers to the textile industry in the EU.

Solid PFAS parts are widely used in textile machinery production, especially where extreme conditions prevail. Verena Thies, Managing Shareholder Thies GmbH & Co. KG, explains: “Our textile dyeing machines are world leaders and set standards in efficiency and sustainability. They work under pressure at temperatures of up to 140° C using highly acidic, highly basic and/or oxidative or even reductive chemicals. This is precisely why PFAS is needed, for example, in seals and rings, flaps as well as valves for a long-lasting and high-quality machine concept – because there are no alternatives with qualitatively equivalent properties. In addition, PTFE semi-finished products enable a sliding and gentle contact with the textile fabric in ecologically important techniques in the transformation of textile wet finishing."

PTFE and also FKM are fluoropolymers (fluoroplastics and fluoroelastomers), a group within the broad PFAS range of about 10,000 substances which would be banned for production, use and sale in the EU. They are high-tech materials, and as so-called "polymers of low concern" are not a danger to the environment, according to the OECD. Furthermore, these components are installed inside a machine and exchanged or disposed of properly. PFAS such as PTFE and FKM must be exempted from the ban, demands the VDMA in its position paper.

"In this way, the association also supports the approach taken in Great Britain. With the 10,000 substances, everything is lumped together, although the various PFAS groups are very different," warns Dr Sarah Brückner, Head of VDMA Environmental Affairs and Sustainability. "We should take our cue from the UK and look at the substance groups in a differentiated way."
Apart from several types of dyeing machines, PFAS components are indispensable in textile drying machines (e.g., conveyor dryers, tumblers and stenters) and damping machines. They are also used in fully automatic chemical dispensing systems and pressure vessels for thermochemical treatment of textile recycling material, heat recovery systems and wastewater treatment technology. This means that a lot of machines needed for a sustainable textile production would be affected by the PFAS ban.

VDMA Textile Machinery will take part in the ongoing EU public consultation. The association will describe indispensable key functionalities and conditions of use in the textile machinery sector as well as the consequences for the companies and the customers in the EU if the ban is imposed. The consultation ends on September 25, 2023, and VDMA urged its members affected by the planned restriction to participate in the consultation at an early stage. This is the only way to ensure that the broad scope of the mechanical and plant engineering sector is represented.

Finishing machinery specialist Monforts has secured a number of major orders from textile manufacturers in Central and South America recently, and was pleased to welcome a high number of visitors from the region to its stand at ITMA 2023 in Milan from June 8-14.

Among new orders are those for three Montex stenters delivered to the AustralTex Group in Argentina and a further Montex range to denim manufacturer CIT in Brazil. Guatemala’s Global Textiles placed an order for its second Montex stenter, while Mexico’s Zentrix ordered its third and Avante, also in Mexico, has opted for its sixth.

Elsewhere, orders have also been placed for the delivery of three new Montex stenters to one of Pakistan’s major corporations, as well as a new Thermex dyeing range to nonwovens manaufacturer Orsa in Italy. Further orders – both for new machines and retrofit modules – are now anticipated following ITMA 2023, which attracted over 111,000 visitors to Milan.

“Visitor footfall at ITMA 2023 was well beyond the company’s expectations, and we were especially pleased at the constant number of visitors from South American companies, as well as from Asia and Europe,” said Monforts Marketing Manager Nicole Croonenbroek. “We were able to provide them with detailed information about our portfolio of machines and technologies digitally and fielded an unprecedented number of serious enquiries, many of which promise to turn into new business.”

Monforts Montex stenters for processes such as drying, stretching, heat-setting and coating, she added, are already the industry standard for the fabric finishing industry, providing a number of advantages in terms of production throughput and especially in energy efficiency and resource savings. Other key technologies in the Monforts portfolio include relaxation dryers, Thermex dyeing ranges and Monfortex compressive shrinking ranges.

Montex®Coat
“We were also very pleased with the interest in the Montex®Coat, the latest addition to our range of technologies, which we displayed in Milan,” Croonenbroek said.

The Montex®Coat can serve a very diverse number of markets and enables full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments, as well as solvent coatings. Knife coating, roller coating or screen printing can also all be accommodated with this system. It provides 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.

Many refinements have been made to the Montex®Coat in the past few years, resulting in higher coating accuracy and the resulting quality of the treated fabrics. A number of advanced new improvements were introduced in Milan, including automatic edge limiters for immediately adapting to new coating widths and a new and simplified hand-held control device. These save considerable time in setting up the machine and ensuring consistent production.

The Montex®Coat unit displayed in Milan was sold to Vietnamese company Thai Tuan during the show.

Just in time for ITMA 2023 in Milan, the flat knitting machine manufacturer STOLL has launched its new collection COLOR IN KNITTING. It holds a range of knitting techniques that were ideated for novel super fine machine gauges such as the E20.

In addition, STOLL reveals its internal design workflow, showcasing how digital software tools can speed up the design process. The core of this is k.innovation CREATE DESIGN. Through the utilization of STOLL’s jointly developed design software solution, k.innovation CREATE DESIGN, in collaboration with @KM.ON, the shape and structures of a garment, can be digitally created, allowing for its simulation before it is even knitted. The interfaces to various external 3D software tools, allow for a realistic representation of the garment facilitating faster design decisions. Once the virtual knits, made in the CREATE DESIGN software are ready for manufacturing, it will be send to a knitting technician for further processing in k.innovation CREATE PLUS, This significantly speeds up product development while reducing communication issues between designers and technicians.

Sustainability and responsible handling of precious natural resources were key factors driving the development of the latest trend collection, COLOR IN KNITTING. STOLL-knit and wear®, a technique that stands for seamless knitted garments, can play a significant role in reducing waste. In addition, fewer process steps are required in the production chain - with advantages for production efficiency.
For another highlight of COLOR IN KNITTING, the STOLL creatives have worked on imitating different yarn effects with knitting technology such as slub yarn optics or the simulation of fabrics like crepe de chine/crepe georgette

On the occasion of the 150th anniversary of STOLL, COLOR IN KNITTING features a selection of vintage pattern replicates. These patterns can be found in STOLL’s extensive sample archives in Reutlingen. It is impressive to learn that all these former fabric constructions can still be replicated today and also reinvented with todays machine features. This approach showcases the steep progression of technical advancements over the past 150 years.

STOLL´s latest trend collection culminates in the creation of an invaluable resource: the book “Color in Knitting: By Designers, for Designers”. This publication aims to cater to a diverse audience by presenting a comprehensive guide to designing with colors using various flat knitting technologies and will be presented in the chapter "Book release".

With combined regional, global, and industry specific expertise, the Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) will make its debut from 28 February – 1 March 2024. Following the signing of a memorandum of understanding (MOU) in late March, Messe Frankfurt (HK) Ltd and the Vietnam Trade Promotion Agency (VIETRADE) announced the new international fair for the entire textile value chain. The three-day platform will be staged at the Saigon Exhibition and Convention Center (SECC), Ho Chi Minh City.

Commenting on the new event, Ms Wendy Wen, Managing Director of Messe Frankfurt (HK) Ltd, said: “With Intertextile Apparel in Shanghai a prime example, our Texpertise Network provides the ideal global framework from which to launch this diverse, comprehensive platform for the integrated textile supply chain. VIATT itself will capture the essence of Texpertise in one platform – a diverse, one-stop sourcing event for buyers across all categories, from garments, fabrics, yarns and fibres, to textile machinery, technical textiles and nonwovens, and everything in between.”

Discussing the event’s potential, Mr Le Hoang Tai, Deputy Director General of the Vietnam Trade Promotion Agency (VIETRADE), said: “Vietnam is one of the world’s leading textile producers and exporters, and going from strength to strength as one of Southeast Asia’s manufacturing hubs. Our establishment has many years of experience organising trade fairs throughout Vietnam, and together with Messe Frankfurt we are excited to help international fairgoers unlock the potential of the country’s fast-growing textile market. In addition, Ho Chi Minh City’s accessibility, and Vietnam’s proximity to other leading textile-producing nations such as Bangladesh, Cambodia, China and India, make it the logical venue to host an event of this nature.”

Many international textile manufacturers have been expanding operations into Vietnam, augmenting an already strong domestic industry. According to the Vietnam Textile and Apparel Association (VITAS), the country’s textile and garment industry achieved staggering annual growth of 20 – 26% from 2018 – 2022. Participation in international trade agreements such as the Regional Comprehensive Economic Partnership (RCEP), the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), the EU–Vietnam Free Trade Agreement (EVFTA), and the Indo-Pacific Economic Framework for Prosperity (IPEF)[2], bodes well for future growth.

As one of the world’s biggest importers of textile machinery, and a consistent importer of fabrics, yarns and fibres, garment production is the cornerstone of Vietnam’s industry. The country utilises cotton and functional materials to produce casualwear, childrenswear, swimwear, workwear, and much more, with sportswear an especially fast-growing category, and high-utility garments expected to achieve high exports.

By linking textile players from across Asia, Europe and beyond with this market, VIATT 2024 is willing to play an important part in shaping the future of Vietnam’s industry. Next year’s fair will host an extensive mix of international and domestic exhibitors covering multiple textile sub-sectors, including garments, apparel fabrics and accessories, yarns and fibres, digital printing, home textiles, technical textiles and nonwovens, textile processing, textile machinery, and more.

Exhibitors and buyers can utilise the fair’s global business matchmaking service, where connections are made based on the specific needs of each party. In addition to the fair’s main function as an international trading platform, its fringe programme will facilitate participants’ networking with industry leaders and offer diverse market insights via various seminars, forums, and panel discussions.

The Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) is organised by Messe Frankfurt (HK) Ltd and the Vietnam Trade Promotion Agency (VIETRADE). Covering the entire textile industry value chain, the inaugural edition will be held from 28 February – 1 March 2024 at the Saigon Exhibition and Convention Center (SECC), Ho Chi Minh City.

Fong’s Europe will showcase the advanced features of its THEN Smartflow TSF at ITMA 2023.

These include the machine’s smart fabric transport system which ensures extremely even dyeing of the fabric through accurate control of the nozzle pressure and pump power, with movement through the machine via an PLC-controlled plaiting system and variable chamber adjustment depending on fabric characteristics.

The machine is equipped with a heat exchanger enabling it to heat the dyeing liquor quickly and efficiently, to reduce energy consumption. Its bath preparation unit and chemical dosing system ensure accurate and precise dosing of chemicals, dyestuff and salt, reducing chemical waste and optimising results while reducing process times.

The Smartflow TSF operates with a low liquor ratio of down to 1:2.5 with full loading of synthetic fabrics, which means that it requires less water to dye a given amount of fabric compared to traditional dyeing machines. This not only reduces the consumption of water and steam, but also the amount of wastewater generated.

The machine's control panel is easy to use, allowing operators to programme and monitor processes with ease.

Groz-Beckert will be represented at ITMA with its six product sectors and will showcase its various innovations. The presentations at the booth will be supported by augmented reality applications. This allows visitors to discover the products both live and virtually.

The Knitting product sector will be represented at the Groz-Beckert stand with its four product groups circular knitting, flat knitting, legwear and warp knitting. In the circular knitting segment, for example, two newly developed knitting systems will be on show which have been realized in collaboration with machine manufacturers. The developments focus on energy savings, extended cleaning intervals and increased process reliability.

In addition to the machines for weaving preparation, the Weaving product sector will present its recently expanded portfolio of technical weaving reeds. The new weaving reeds make it possible to supply customers who produce fabrics with high densities. The weaving reeds are used in the production of special fabrics, for example, in technical filtration, membrane technology, solar cells or touch screens.

Products and services for classic needling and hydroentanglement will be presented by the Felting (Nonwovens) product area. In the field of felting needles, visitors can look forward to two innovations: a new notch shape and the Groz-Beckert felting needle module. In the felting needle module, the needles are embedded as a module in a plastic mold for the first time. The needle modules are characterized by high deformation resistance and offer new dimensions in needle density.

For the production of tufted floor coverings such as carpets, bath mats or artificial turf, the Tufting product sector will be presenting its proven Gauge Part system.

Various new and further developments will also be shown by the Carding product area. For those interested in the nonwovens industry, for example, the world's finest Interlocking wire for reduced risk of crashis included. For customers of the spinning industry, the division will be presenting further developed stationary flats and revolving tops. The new revolving tops have been adapted to the processing of fine yarns, while the stationary flats have been provided with a new, resistant aluminum profile.

The Sewing product sector is focusing on the presentation of its special application needles, SANTM. The sewing machine needles of the SANTM series have been specially developed for demanding sewing operations – e.g. for sewing technical or finest textiles. The division will also be presenting its new Needle Finder. The Needle Finder is an interactive tool in the online customer portal that helps customers select the right needle.
