From the Sector

Groz-Beckert offers interested machine builders various cooperation opportunities to jointly develop new products or improve existing ones. In collaboration with Vanguard Pailung, a manufacturer of ultra-high-speed knitting machines for body-size products, Groz-Beckert has developed an innovative slider needle for a new generation of machines. Groz-Beckert's Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects.

In June 2022, Vanguard Pailung approached Groz-Beckert with a cooperation request. Together with Groz-Beckert, the company wanted to develop a new needle solution for an innovative ultra-high-speed machine. Together with an innovative slide needle, the new machine was to exceed the speed and productivity of known knitting systems of large circular knitting machines.

Machine and needle development ran in parallel and were closely coordinated. The first field tests took place in the Vanguard Pailung laboratory in Monroe/NC, USA in February 2023. The successful development was presented to a wide audience for the first time at ITMA 2023 in June.

Unlike latch needles, slide needles do not form the stitch via a needle latch, but via a slide that is controlled by its own channel. The advantage of this is that the needle can withstand high speeds, as there is no latch impact, which in turn increases productivity.

The use of the new slide needle in ultra-high-speed machines ensures a particularly high level of process reliability. With the new needle variant, the closer is guided safely and precisely in the groove in the needle shank. At the same time, the base of the needle shank is closed, which ensures maximum stability. The slider needle reliably prevents the so-called latch impact and thus makes a decisive contribution to process reliability. Its use ensures a uniform and speed-independent loop structure, even at maximum speeds.

SHIMA SEIKI ITALIA S.p.A., Italian subsidiary of leading Japanese computerized knitting solutions provider SHIMA SEIKI MFG., LTD., will exhibit at the 94th edition of the Pitti Immagine Filati exhibition in Florence, Italy (24th-26th January 2024). It will exhibit as part of the CustomEasy section, which involves the concept of Fashion at Work and explores customization in the presence of textile machinery and design software, represented in part by SHIMA SEIKI's lineup of WHOLEGARMENT® knitting machines and APEXFiz® design software.

The new SWG-XR® flagship machine features 4 needle beds for all-needle knitting of high quality WHOLEGARMENT® products using the company's original SlideNeedle™, in addition to a re-designed sinker system and a compact, light-weight carriage featuring 4 systems as well as auto yarn carriers. All contribute to increased productivity of more than 25% over the previous MACH2®XS machine, as well as increased product range using a wider variety of yarn for supporting knits for all seasons, and higher quality for knitting beautiful fabrics and silhouettes; even items that were impossible to knit with the MACH2® series, including punch-lace patterns, variable stitch knitting and intarsia knitting. Setting new standards for the next generation of waste-free, sustainable WHOLEGARMENT® knitting, SWG-XR® at Pitti Filati will be shown in 15L and 18L as well as a prototype machine in 22L.

APEXFiz® subscription-based design software supports the creative side of fashion from planning and design to colorway evaluation, realistic fabric simulation and 3D virtual sampling. Virtual samples are a digitized version of sample making that are accurate enough to be used effectively as prototypes. By replacing physical samples, virtual samples reduce time, cost and material that otherwise go to waste.

The product planning capability of APEXFiz® is enhanced by several web services featured as part of the SHIMA SEIKI Online Services (SHIMA online) web platform. These include SHIMA Datamall™ digital content web service that allows users to search, browse and purchase a variety of useful data for streamlining the planning and production of fashion items, as well as the recently renewed yarnbank® digital yarn sourcing web service that offers digitized yarn data by yarn companies from around the world for download and use in virtual sampling. SHIMANAVI® e-learning system is also part of the online platform.

Mahlo GmbH + Co. KG will present its systems and solutions for efficient and high-quality textile production and finishing together with Shanghai Kuantex at ITMA Asia (November 19 and 23). The focus will be on the machine manufacturer's new straightening concept, the Orthopac RXVMC.

"In the new straightening concept, special attention was paid to the straightening mechanics and their interaction with the analysis electronics of the probe system," explains Sales Manager Thomas Höpfl. The control concept is also new. A probe group at the leveler infeed detects distortions even before they reach the correction rolls. In this way, the rolls are brought directly into position and the fabric is corrected from the very first centimeter. A scanner group at the outfeed 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 fabrics sensitive to distortion.

Also contributing to high-quality textile production and finishing is the Famacont PMC for controlling weft and stitch course density, which will also be on show at ITMA Asia. The Famacont PMC-15 uses a sensor to measure the yarn or stitch density and compares it with the target value stored in the recipe data management system. The detected deviation of the yarn density from the target value is used to fully automatically regulate the leading during the needling process on the stenter frame. Interested parties can have the mode of operation explained to them at the Mahlo booth with the help of a demo tower and their own or provided fabric samples.

Another major topic remains Industry 4.0, because the best measured data is of no use if it cannot be utilized. Mahlo has continuously developed its digital environment mSmart. "Our systems generate data that the customer can use immediately to regulate goods on-line. At the same time, all measured values are backed up in our data management system mLog enhanced and can be retrieved at any time. With this historical data, processes can be optimized and weak points in the process can be minimized," explains Sales Manager Thomas Höpfl.

ITMA 2023 was a successful platform for the flat knitting machine manufacturer STOLL to present its latest new developments. The business unit of the KARL MAYER GROUP will be following up this fair on 3 July with the launch of a further innovation package. With the solutions contained in this package, STOLL will be offering its customers additional added value when using their flat knitting machines - in line with the concept of bundling innovations.

The new features include an optimised central lubrication system that reduces both maintenance effort and oil consumption, this as standard from July 2023 for all models of the CMS and ADF series produced in Reutlingen.
Compared to the previous optional variant, it ensures more efficient and comprehensive lubrication. All needle bed elements, from the holding-down jack to the coupling part and intermediate slider to the selection jack, are now supplied with oil. The machine itself recognises whether lubrication is required. Independently of this, the lubrication intensity and oil distribution can be adapted to the individual machine conditions by setting various parameters, if required. To ensure that the required amount of lubricant is reliably supplied, a message is sent if the level is too low.

In addition, a new oil drain container as standard equipment for all CMS and ADF models catches used oil from the needle bed under the machine. This prevents soiling of floors or knitted fabrics. The emptying of the container can be efficiently managed by an adjustable reminder function. The neat and at the same time sustainable solution does not require cleaning agents or hoovers and offers the possibility to reuse the oil after cleaning through special filters, if necessary.

Users of CMS and ADF belt take-down machines can benefit from optimisations around the belt take-down. Thanks to the new STOLL innovation package, this can be turned forwards and backwards by means of a switch as standard in order to easily eliminate fabric wraps and thus reduce maintenance times. In addition, a mirror, which is also fitted as standard, ensures a simple visual check of the belt take-down.

Another solution of the STOLL innovation package from July 2023 includes new cams that enable split-stitch implementation without cam box modification. This reduces manual effort and thus conversion times and costs. The feature is standard on all fine gauges ADF and CMS machines.

For the W machines from STOLL, there is now a further inlay yarn carrier, the Qt, in addition to the previous Qw yarn carrier. The extension means that the number of inlay yarn carriers used in a system can be increased from the previous one to three. No additional system is required for the weft yarn, and the process steps weft yarn insertion and knitting take place in the same system.

International textile producers meet again in Istanbul, Turkey, from June 14 – 18, 2022 on the occasion of the ITM + Hightex Exhibition. In Hall 9 (Hightex) the exhibitors will present the complete industry value chain from nonwovens raw materials, production machines and accessories to the endproduct. The related industries covered include hygiene, filtration, fabrics and apparel, medical, automotive, wipes, home furnishings and upholstery. DiloGroup offers tailor-made production systems from one supplier and will inform about its portfolio and the latest equipment developments from fibre opening to the finished felt.

DiloGroup will inform about complete lines as well as high speed needlelooms for spunbonds. A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further. The new needle pattern 8000X is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

Another strong pillar of the sales program over decades has been fibre preparation and high speed webforming equipment for other nonwoven technologies. The further development of the high-speed layering principle “Hyperlayer” made progress for better CD strength through a combination of inline cards and crossline card with crosslapper. Particularly, carding machines in a working width above 3.5 m up to 5.1 m have been supplied by DiloSpinnbau as complete high speed carding systems, comprising two or even three cards in a line to directly feed the hydroentangling units of various suppliers. Together with DiloTemafa not only have high throughput rates been achieved in the fibre preparation section of the line but also dedusting filtering and air-conditioning systems have been successfully engineered and integrated.

Together with Sicam, Dilo has combined know-how for hydroentangling technology and therefore can provide complete lines as general contractor including equipment for cutting, winding and packaging.

Another interesting machine is the 3D-Lofter, first presented during ITMA 2019 in Barcelona, which offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts with or without repeat are two examples for this technology which explores new application areas for needlefelts.
The 3D-Lofter technology may also be used “inverted” as “IsoFeed” for filling up bad spots in web mats and thus achieves a better homogeneity of spunlace or airlay products.

The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

At the forthcoming Texprocess, Techtextil and Heimtextil shows taking place in Frankfurt from June 21-24 – members of the Swedish Textile Machinery Association TMAS will be showcasing a range of solutions aligning with the growing trend for more localised and automated textile manufacturing.

Digitalisation and the push for more sustainable, shorter and less expensive supply chains are currently making manufacturing in high-cost countries within Europe more attractive and there have been many other contributing factors to this over the past two years.

The Covid-19 pandemic exposed the vulnerability of many countries to shortages of essential items like PPE while at the same time making the full exploitation of new digital options essential during national lock-downs and long periods of restricted travel. The escalating cost of global transportation, as well as the growth of online retailing and the associated benefits of on-demand digital manufacturing, are further reinforcing the many benefits of short-run and near-shore new operations.

Secure supply
At Texprocess, for example, Eton Systems will be unveiling its latest Ingenious software solution which further enhances the company’s Opta Unit Production System (UPS) introduced in 2021.

“Our automated technology has already had a great impact on the productivity of thousands of garment production lines,” says Eton’s Managing Director Jerker Krabbe. “Our systems help producers across the world to reduce repetitive manual tasks and increase efficiency, which evens out some of the differences between production in high and low-cost countries, making reshoring a feasible option. Creating a diversified production portfolio with a mix of production facilities, some closer to home, makes for a more secure product supply.”

Flexibility
Imogo meanwhile recently installed the first industrial scale dyeing system in Sweden for many years. The Dye-Max spray dyeing line has the potential to slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems. It is capable of carrying out the application of a wide range of fabric pre-treatments and finishing processes, providing users with unbeatable flexibility in production.

“Here in Scandinavia, we are currently seeing an explosion of companies developing sustainable new cellulosic fibres – many from waste clothing – but a problem is that all of the environmental benefits they deliver can potentially be lost in the further processing, and especially in conventional dyeing,” observes the company’s Founding Partner Per Stenflo. “The Dye-Max system positively addresses this, but interest in it has not just been confined to Europe. We are currently seeing a lot of activity in Turkey – largely as a near-shore partner to European brands – but also in Bangladesh.”

Robotics at Heimtextil
ACG Kinna Automatic specialises in automation solutions for filled products such as quilts, pillows and mattresses and its live demonstrations of robotics in action have proved a magnet for visitors to Heimtextil. This year’s show will be no exception.

“The use of robotics is now standard across many industries dealing in solid goods, but the handling of soft materials such as textiles is a little more complex,” says Managing Director Christian Moore. “Nevertheless, it’s something we have successfully mastered, and our robotic systems are proving highly beneficial to their users. There is no ‘one-size-fits-all’ solution when it comes to automation and our approach is always to carefully examine where it will make the difference in each bespoke system. A focus is on identifying and eliminating bottlenecks which will increase product flows.”

During the Covid-19 pandemic, ACG Kinna drew on all of its automation know-how and extensive network of contacts to build a new nonwovens fabric converting and single-use garment making-up plant in a matter of weeks, in order to supply the Swedish authorities with urgently-needed medical gowns.

Instant colour
Localised textile production is also booming in the USA, where Coloreel has recently secured multiple orders for its instant thread colouration technology via its US partner Hirsch.

“Coloreel technology enables the high-quality and instant colouring of a textile thread while it is actually being used in production and can be paired with any existing embroidery machine without modification, while also making it possible to produce gradients in an embroidery for the first time,” explains VP of Sales Sven Öquist.

“Advanced rapid colour formulation software and high-speed drive technology allow a single needle to carry out what it previously required many multiples of them to do – and with much more consistent stitch quality. By instantly colouring a recycled white base thread during production, our system enables complete freedom to create unique embroideries without any limitations. Colour changes along the thread can either be made rapidly from one solid colour to another, or gradually, to make smooth transitions or any colouring effect desired. This provides big benefits when it comes to sustainability and design creativity.”

Milestone
Svegea will be promoting its latest EC 300 collarette cutting machine at Texprocess 2022. This machine is used by garment manufacturers around the world for the production of tubular apparel components such as waistbands, cuff and neck tapes and other seam reinforcements. With its E-Drive 2 system and fully automatic FA500 roll slitter, the EC 300 has an output of around 20,000 metres per hour.

“Advances in automation are only making the specialised, bespoke machines we engineer even more efficient and we are expecting a very busy year,” says Managing Director Håkan Steene. “The garment components our collarette cutters produce make it logical for them to be integrated into the operations of making-up operations, wherever they are.”

Sensors
The advanced yarn tension monitoring technologies of Eltex of Sweden meanwhile play an essential role in rectifying defects in  weaving, tufting and composite reinforcement operations.

“A correct tension of the warp and weft threads ensures proper machine operation,” explains Eltex Global Marketing and Sales Manager Anoop K. Sharma “The constant tension monitoring and automatic control of the tension of the thread help to overcome unnecessary problems.

“We continue to make advances in both the hardware and software of our tension monitoring systems, such as the EyE™ for the warping process. With the EyE™, the yarn tension values from all yarns are continuously updated and displayed on screen. In addition, tension values outside the warning level are indicated both on the sensor’s LEDs and on the screen for complete quality control. No fabric can be woven without the appropriate and correct tension.”

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, through its Italian subsidiary SHIMA SEIKI ITALIA S.p.A., will participate in the A+A 2021 International Trade Fair for Safety, Security and Health at Work in Düsseldorf, Germany.

Having achieved recognition as an innovation leader in the flat knitting industry through pioneering inventions such as the world’s first DSCS® Digital Stitch Control System and seam-free WHoLEGARMEnT® knitting, SHIMA SEIKI has entered the field of technical textiles by proposing knitting as an alternative to other manufacturing methods. Through breakthroughs in original hardware and software technology as well as research in new materials, what was impossible to knit in the past can now not only be knit; it can be made to perform even better.

On display will be the company’s SVR123SP computerized flat knitting machine featuring a dedicated loop presser bed that permits full use of inlay technique for the production of hybrid fabrics that feature both knit and weave characteristics, suited to the production of safety-oriented functional fabrics. SVR123SP furthermore features i-Plating inverse-plating capability for increased patterning capability, including the production of jacquard-like patterns in light-weight plain jersey stitch. A variety of knit samples produced on SVR123SP will be presented at A+A featuring anti-bacterial, fireproof and cut-resistant fabrics, including a light-weight cut-resistant apron as an alternative proposal to current heavy vinyl aprons used in the meat packing industry. Safety glove samples knitted on SHIMA SEIKI’s glove knitting  Machine will be presented as well.

Also demonstrated will be SHIMA SEIKI’s SDS-onE APEX4 3D design system. APEX4’s capability for virtual sampling is especially effective in streamlining the production process. Ultra-realistic simulation capability allows the use of virtual samples for evaluating design variations without producing actual samples for each variation. Smart, speedy and sustainable production is possible by minimizing the time, cost and resources normally required with sample-making.

For the second time the Innovative Textile and Apparel Show opens its virtual fairground this year. For the second time, Mahlo takes the chance to get in contact with customers from all over the world. Mahlo will present the latest systems and solutions for efficient and high-quality textile production and finishing, with the focus on process optimisation in a digital environment.

In the textile industry, Mahlo is known for high-quality automatic weft straighteners, whether roller or needle straighteners, whether for the finest textiles or heavy fabrics - interested parties can find out about the right equipment for their specific requirements.

Process control systems such as the Patcontrol PCS for pattern recognition and the Famacont PMC for controlling weft and stitch course density also contribute to textile production and finishing. Mahlo wants to support manufacturers in optimising their production processes and thus also the end product in a cost-efficient way.

Solutions for technical textiles and nonwovens
Support in the production process is also available for technical textiles and nonwovens. The focus here is on the Qualiscan QMS quality measurement system. The modularly designed system, which consists of sensors and measuring frames, measures, logs and controls critical parameters such as basis weight, moisture or layer thickness across the entire fabric width. Depending on the application and task, different measuring methods are used for this purpose.

Flat knitting solutions provider SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its Hong Kong subsidiary SHIMA SEIKI (HonG KonG) LTD., will participate in the ITMA Asia + CITME 2020 exhibition to be held at the national Exhibition and Convention Center in Shanghai, China in June.

Through its exhibit theme—Step Beyond—SHIMA SEIKI will present its vision of the future, while addressing a variety of solutions for the new normal, including proposals in Factory Automation, Digital Transformation (DX), and various online solutions.

At ITMA Asia SHIMA SEIKI will be making proposals for factory automation centered around the special manufacturing capabilities of our WHOLEGARMENT® knitting machines. WHOLEGARMENT® knitwear can be knit in one entire piece without the need for linking or sewing, and allows for on-demand knitting. SHIMA SEIKI will present its WHOLEGARMENT® knitting technology in the form of two of the latest machines. The flagship MACH2XS is the one of most advanced flat knitting machines, featuring proprietary four-needle bed and Slideneedle™ technology combined with spring-type moveable sinkers and i-DSCS+DTC® Digital Stitch Control System with Intelligence and Dynamic Tension Control, and capable of all-needle knitting of WHOLEGARMENT® items. MACH2XS is presented in ultrafine 18L gauge, shown for the first time in China. Also shown for the first time in China, MACH2VS, a flexible V-bed machine capable of knitting WHOLEGARMENT® knitwear using every other needle, or conventional shaped knitting using all needles. It also features spring-type moveable sinkers and i-DSCS+DTC® Digital Stitch Control System with Intelligence and Dynamic Tension Control. MACH2VS is presented in ultrafine 18G with auto yarn carriers as a prototype option.

ITMA Asia will also be the occasion for a sneak preview of next-Generation 4-bed WHOLEGARMENT® knitting technology. The new machine is named SWG-XR, adopting the SWG moniker from the first-generation WHOLEGARMENT® knitting machine introduced back in 1995. The "X" represents 4 needle beds arranged in an Xshaped formation as per the original SWG-X machine, while "R" stands for Reborn and Revolution, referring to a renewal of SHIMA SEIKI's WHOLEGARMENT® knitting that raises the technology to unprecedented levels. By increasing the number of systems from 3 to 4 and featuring auto yarn carriers, SWG-XR allows even higher productivity and vastly improved range of knitting.

In order to further support efforts in DX in the fashion industry, SHIMA SEIKI has released three new online services over the past year which will also be showcased at ITMA Asia: 'APEXFiz™' subscription-based design software; 'yarnbank ™' digital yarn sourcing web service; and 'SHIMAnAVI™' e-learning service.

At this year’s trade fair „SIMAC Tanning Tech“, PFAFF Industrial, together with DÜRKOPP ADLER and the regional agency DAP ITALIA, will present the latest solutions for shoe and leather processing. The fair will take place in Milan from 19th to 21st of February 2020. The joint booth is located in Hall 14, No. C09.

PFAFF News and Highlights:

PFAFF 3806
New integrated workplace for closing rub-down seams, such as heel-, front- and side seams on street shoes, slippers and leg boots. The PFAFF 3806 is equipped with two-thread chainstitch high-speed seamer head PFAFF 5487 with drop feed and variable top feed, high lift and adjustable top feed pressure, which ensures consistently high quality. Reinforcing tapes, which may be applied from top impart greater durability to the seams and prevent fine leathers from being pulled out of shape. Automatic control sequences (via parameter or photocell) reduce the manual handling and increase the process reliability and output.

PFAFF 1591
On the fair PFAFF INDUSTRIAL will show its electronic single-needle shoe post-bed machine with touch-control panel, new thread trimmer for short thread ends (< 5 mm) and new programmable thread tension. The key benefit of “programmable thread tension” is that suitable thread tensions can be applied for different material thicknesses and/or for different seam sequences (as these can be programmed on electronic machines). The tensions can be accessed and/or set via a knee switch or stitch counting. Manual setting of the thread tension, as is common with current shoe machines, is no longer necessary with the programmed thread tension.

PFAFF 8303i
The ot-air taping machine for welding continuous seams on water-resistant, waterproof and breathable materials will be exhibited as “shoe version” with very small/slim post from back. Effortlessly shoe uppers with small radii can be taped. The slim post and the differential feed (via two separate drive motors for the top and bottom feed roller) ensures absolute neat seams and a requested fullness und shaped parts.
