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 MFG., LTD. of Wakayama, Japan will participate in the A+A 2023—Safety, Security and Health at Work International Trade Fair in Düsseldorf, Germany (24th-27th October 2023). On display will be the company's latest safety-related technology through its new SPG®-R pile glove knitting machine and the prototype SFG®-R next-generation glove knitting machine. Each of these machines drew attention at SHIMA SEIKI's booth at the International Textile Machinery (ITMA 2023) Exhibition in Milan.

SHIMA SEIKI's original SPG®, developed in 1979 as the world’s first automatic glove knitting machine to produce seamless pile-knitted gloves, is now reborn as a next-generation model. Pile gloves feature special traits that include cushioning, shock-reduction and thermal insulation and cold protection, making them popular especially in the field of industrial safety. Now, SPG® is redesigned from the ground up and re-introduced as the SPG®-R. The new SPG®-R features a new moveable sinker system with selectable loop presser function. Combined with a new belt-driven carriage it allows SPG® to provide efficient and reliable production of fashionable, high-quality pile gloves. Shown in 7 gauge at A+A, SPG®-R surpasses the previous generation with pioneering technology, improved capability and reliable productivity.

SHIMA SEIKI's original product on which the company was founded was the fully automated seamless glove knitting machine. While the original model evolved to become the current SFG® series, SFG®-R exhibited at A+A is its spiritual successor. With a new sinker system, a belt-driven 2-cam carriage and auto yarn carriers SFG®-R is a completely new machine for knitting gloves that conform better to the shape of the hand for improved fit. Furthermore its greater design potential offers users the opportunity to break out of the work glove market and into the fashion market. SFG®-R is shown as a prototype next-generation model in 12 gauge at A+A.

Also demonstrated will be SHIMA SEIKI's APEXFiz® design software. The importance of design software is made even more significant by the new patterning capabilities of SPG®-R and SFG®-R. Both machines now feature increased design potential that allow each of their products—pile gloves and work gloves, respectively—to expand their market into fashion. APEXFiz® is available for developing these designs. Furthermore virtual sampling on APEXFiz® 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, thereby minimizing the time, cost and resources normally required with sample-making, supporting smart, speedy and sustainable production.

SHIMA SEIKI MFG., LTD., together with its Brazilian representative BRASTEMA TECNOLOGIA TÊXTIL LTDA., will host the Tech Fashion shows, a series of private exhibitions held at two locations in Brazil in July and August. The exhibitions will be a showcase for the company’s latest computerized flat knitting technology, presented through fashion shows, machine exhibits and the latest knit samples featured at ITMA 2023. The event is organized by the Fashion Committee of Fitemavest, consultants to Brazil's fashion market, and will feature presentations by CS DESIGN STUDIO designer Cecilia Seibel.

Technological displays include a full lineup of SHIMA SEIKI flat knitting machines, ranging from the MACH2XS WHOLEGARMENT® knitting machine to N.SVR122 computerized shaping machine, as well as the SFG-I fully automated glove knitting machine. Exhibited machines vary between locations. Details are given below under ‘Exhibited Technology.’

The potential of each of these knitting machines are maximized in combination with the SDS®-ONE APEX4 3D design system and APEXFiz® design software. At the core of the company’s "Total Fashion System" concept, SDS®-ONE APEX4 and APEXFiz® provide comprehensive support throughout the apparel supply chain, integrating production into one smooth and efficient workflow from yarn development, product planning and design to production and even sales promotion. Especially effective is their capability to improve on the design and evaluation process with virtual sampling. Ultra-realistic simulation capability on SDS®-ONE APEX4 and APEXFiz® allows virtual sampling to minimize the amount of time, cost and material spent during the sample-making process

The fashion show will feature the newest creations in WHOLEGARMENT® and other knitwear.

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.

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.

Mimaki Europe, a provider of industrial inkjet printers, cutting plotters, and 3D printers, is debuting the new Tiger600-1800TS, Mimaki’s most productive sublimation transfer printer, on its stand at ITMA 2023. This latest high-speed, compact and robust roll-to-roll inkjet printer has been designed to accelerate the analogue to digital transformation within the textile printing industry.

The Tiger600-1800TS boasts a maximum printing speed of 550 m2/h (143% faster than the previous model) owing to the renovated high-speed printhead and Mimaki’s proprietary image quality enhancement technologies. The printer’s size has also been halved compared to the previous system, with the paper mounting and winding system both located at the back of the machine. This smaller footprint enables customers to easily install multiple units to meet fluctuating demand, whilst also increasing overall production capacity.

A further environmental benefit of the Tiger600-1800TS will be the bluesign® certification of its MLSb510 series sublimation transfer inks. This certificate, expected to be awarded in June 2023, will provide assurance that these inks are of highest quality combined with due consideration for the safety of consumers and print operators, and environmental conservation, and therefore, contributing to the sustainability of the textile industry.

Mimaki’s expertise in developing reliable, easy-to-use and efficient solutions has also not faltered in the development of the Tiger600-1800TS. The printer’s ink tanks can be replaced without interrupting the printing process, minimising down time. Maintenance of the printer is also reduced with its roller paper feeding method eliminating the need for the application of adhesives onto a belt.

Mimaki Europe, a provider of industrial inkjet printers, cutting plotters, and 3D printers, has announced the introduction of two technologies at ITMA 2023: a Textile Pigment Transfer Printing System and the Neo-Chromato Process. These innovations are showcased for the first time, and ahead of commercial availability, at the exhibition in Milan, Italy, solidifying Mimaki's commitment to sustainable and environmentally friendly solutions in the textile printing industry.

Mimaki’s New Textile Pigment Transfer Printing System
The transfer printing method is more sustainable than both analogue and digital textile dye printing methods with zero water consumption and substantially lower CO₂ emissions. The system comprises three essential elements: the Textile Pigment Ink, the Transfer System and the Textile Pigment Transfer paper, Texcol®.

Texcol® is a transfer paper pioneered by Dutch paper manufacturer, Coldenhove that allows for transferring a digital print using an environmentally friendly 3-step transfer process to create a vibrant application on a wide range of materials, including natural fibres. The design is initially printed onto the paper using a customised TS330-1600 - Mimaki’s high-volume, high-quality dye sublimation printer - and Mimaki’s new pigment inks developed for the process. The module that adapts the TS330-1600 will be available as an option for existing and new Mimaki customers in Q3 2023 but is being previewed on the Mimaki stand at ITMA.

Mimaki’s new Textile Pigment Ink is undergoing bluesign certification before commercial availability. bluesign is a renowned certification programme that ensures the highest levels of safety, environmental friendliness, and sustainability within the textile and apparel industry.

As the final stage, the Texcol® paper undergoes a one-step waterless process, through an entry-level calendar machine onto the textile of choice.

Cyclical textile technology
Mimaki is also debuting its new, unique Neo-Chromato Process, which revolutionises the reuse of coloured polyester textiles.

By decolourising polyester textiles that have been dyed using dye sublimation technologies, this innovative process allows materials to be re-printed or dyed immediately, contributing to a smaller circular economy. There is no limit to how many times reused polyester can be treated with the Neo-Chromato Process and the process itself minimises water usage and pollution by enabling the disposal of the absorbent paper and decolouring solvents used in the process as burnable waste.

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.
