From the Sector

KARL MAYER launches its RE 4-1, a new Raschel machine for the efficient production of highly elastic textiles. With this newcomer, KARL MAYER is expanding its Elastomeric series and supplementing the established RE 4-1 as part of its two-product line strategy. With the price-performance ratio, the machine fulfils the requirements of the volume business in particular.

A 170″ version of the machine has already been on sale in China for several months. The pre-release got off to a successful start. Encouraged by the feedback from the market, KARL MAYER has developed an RE 4-1 with a working width of 190″ and will be offering both models to its global customers from middle of July 2024.

The RE 4-1 can be ordered with E 28 and E 32 gauges. The 170" version is also available with E 36. The standard equipment includes KAMCOS® 2, batching device 18 E, Carbon fibre technology and N-pattern drive for controlling the guide bars: stitch-forming GB 1 to GB 3 and inlayGB 4. There are also optional features, including sensors for measuring the yarn tension, laser stop, batching device 34 A, LED lighting and an installation kit.

With its technical configuration, the RE4-1 is optimised for the production of elastic and non-elastic standard fabrics, especially for the underwear sector. One of the top products of the Raschel machine with its high productivity and short amortisation time is elastic Power net. This open-meshed, airy fabric has become an indispensable part of the lingerie and clothing sector. It is often used in the wings of bras as well as for inserts in sports leggings, shirts, jackets and swimwear, where it provides delicate control and comfort. Power net can also be found in semi-technical applications, for example as outer and inner pockets for rucksacks and clothing.
In addition to Power net, Raschel Locknit, Sleek net and Satin net are also part of the production repertoire of RE 4-1. The fabrics with a decreasing density from Raschel Locknit to Satin net also play a role in underwear and clothing production. For their production, filament yarn is threaded in the front two guide bars and elastane in the back ones.

Maintaining a focus on innovation despite the uncertainties that characterize the current international scenario was emphasized during the General Assembly of ACIMIT, the Italian Textile Machinery Manufacturers Association, held in Milan on July 9. ACIMIT president, Marco Salvadè, showcased the data of the Italian textile machinery industry. In 2023, production decreased by 16%, settling at a value of 2.3 billion euros, as did exports, which also fell by 16% (2 billion euros).

China, Turkey, India, and the United States remain the main destinations for Italian textile machinery manufacturers. In 2023, demand for machinery in these markets was weak, but some positive signals emerged in the first quarter of the current year, especially from the Chinese market and again from Egypt, Pakistan, Brazil, and Japan. “2024 will still be a year characterized by many uncertainties,” commented Salvadè, “mainly due to the uncertainty of the geopolitical situation and fluctuations in final demand”.

In an especially difficult international scenario and with a still sluggish market, the Italian textile machinery sector remains a leader alongside a few other Countries, such as China, Germany, and Japan. “Our sector is renowned worldwide for its reliability, know-how, and the uniquely Italian ability to combine tradition and innovation,” noted the ACIMIT president. Accelerating innovation remains crucial, particularly to meet the challenges that await Italian manufacturers in supporting textile companies on their sustainable transition journey.

To highlight the opportunities that the European green transition opens up for technology suppliers, the public section of the ACIMIT General Assembly addressed a very current issue: textile recycling. The EU’s legislative guidelines aim to accelerate the green and circular transition of the textile sector with various actions: from ecodesign to EPR, from waste export regulation to green claims. Meanwhile, there is a growing demand for recycled textile fibers driven by the sustainable policies of brands that should not be underestimated.

Thus, technologies play an important role in providing solutions to companies engaged in the new circularity supply chain: from sorting and selection of garments to preparation phases and recycling processes. During the event several speakers agreed that the experience and capabilities of the Italian textile and textile machinery sector should be fully leveraged at this crucial stage for the entire supply chain. As President Salvadè noted, “Textile machinery companies intend to increase R&D activities in this area, collaborating with their textile customers in the belief that the circular transformation of business models also represents an opportunity for technology suppliers to increase their competitiveness.”

The KARL MAYER GROUP founds a production company in Romania and hires Patrick Mack as an additional General Manager.

In October 2023, the KARL MAYER GROUP founded a production company in Romania to make itself more resilient and strengthen its competitiveness. KARL MAYER ROMANIA S.R.L. will initially start production in Baia Mare, which were rented in February 2024. A move to a new factory building in the neighbourhood is planned in the future.

In May of this year, Patrick Mack took up his position as General Manager at the Romanian subsidiary of KARL MAYER. He will be supported in his tasks by Manfred Reinhold, also at the head of KARL MAYER ROMANIA. Patrick Mack will manage the business locally.

The German-American has already set up a factory for a foreign company in Romania and has a clear idea of his new role: "KARL MAYER ROMANIA is of extreme strategic importance. That is why I want to build a site that fits seamlessly into the manufacturing footprint of the KARL MAYER GROUP. The new production facility should fulfil all KARL MAYER standards, contribute to the improvement of the company as a whole and represent it accordingly," explains Patrick Mack.

Mayer & Cie. presented an overview of its current portfolio in the circular knitting sector at the ITM in Istanbul. Two machine types – the SF4 3.2 III and the Relanit 3.2 HS II – and various smart solutions that make circular knitting more efficient were on display. knithawk, a tool for the optical detection of knitting defects, met with interest among the visitors. The same was true for knitlink, Mayer & Cie's hub for digital solutions. Spare parts packages and conversion kits are also in demand for the long-term value retention of Mayer & Cie. machines.

Relanit 3.2 HS II
The Relanit 3.2 HS mechanical single jersey machine offers high productivity, especially in the context of elastic plating. It processes a wide range of yarns and qualities reliably. It is suitable for processing recycled yarns. Their energy consumption is up to a third lower than that of a circular knitting machine with conventional technology.

In Istanbul, Mayer & Cie. presented an updated version of its flagship, the Relanit 3.2 HS II. The new open-width take down is the single component that attracted the most interest. It ensures a uniform pull-off tension of the knitted fabric over its entire circumference. The knitted hose is only opened below the take-down rollers. Furthermore, the take-dwon is equipped with two drives: one for tensioning, one for rewinding. Both can be controlled separately.

Another innovation of the Relanit 3.2 HS is aimed at reducing downtimes: The needle with predetermined breaking point, which was developed together with Groz-Beckert, prevents it from breaking uncontrollably and, in the worst case, breaking needle butt. The new spring sinker is also a joint development with Groz-Beckert. This makes the Relanit 3.2 HS II run more smoothly, produce less noise as well as with less wear and tear.

SF4-3.2 III for lightweight three-tread fleece knitted fabrics
With its SF4-3.2 III, Mayer & Cie. is addressing a trend in the clothing industry that is reflected beyond Turkey: lightweight, elastic three-thread knitted fabrics in both pure cotton and blends.

New Control 5.0 machine control system
Both ITM machine exhibits were on display with the new Control 5.0 machine control system. Control 5.0 is a prerequisite for using knitlink, the hub for Mayer & Cie's digital applications. In this function, the machine control system attracted interest from various large customers.

In the standard SmartControl version, as shown in Istanbul, a so-called Smart Knob is attached to each machine foot. From there, all the functions that the machine operator needs for his work are available. More in-depth settings, such as those made by the knitting manager, are only possible from a mobile device. Any number of Mayer & Cie. machines can be operated from this at the same time.

knithawk
knithawk, a tool for optical defect detection, inspects the knitted fabric as it is produced. It sits in the single jersey machine directly at the knitting point. If knithawk detects a serious or recurring error, the machine is stopped. The tool also creates an error log.

Machine-specific upgrade and conversion kits
With its upgrade kits, Mayer & Cie. brings technological innovations to existing machines. These range from machine-specific upgrades, such as the Performance Kit for existing Relanit 3.2 models to the Senso Blue RS lubrication system.

In addition to the upgrade kits, Mayer & Cie. offers conversion kits for popular machine types. Two are currently available: for the MV4 3.2 II/MBF 3.2 and the S4-3.2 II/ SF4-3.2 III.

KARL MAYER GROUP has developed a sophisticated system for considerable energy savings when operating the cylinder dryers in its PROSIZE® sizing machines and BLUEDYE dyeing plant.

Saving costs with inline energy recycling
The innovation is called CASCADE and focuses on steam as a heating medium in cylinder dryers. And for good reason: according to the IPCC report by ITMF Zurich, one tonne of steam cost between USD 20 and just under USD 27 internationally in 2021. The new solution relies on reuse to reduce the amount of process energy required.
"CASCADE recirculates parts of the process steam in cylinder dryers, enabling genuine, efficient energy recycling within the machine," explains Karl-Heinz Vaassen, Head of Textile Drying at KARL MAYER.
The customer benefits from significantly lower energy costs and CO2 emissions. With a view to the Asian market, a dryer with 14 cylinders and a running time of 7,000 working hours can achieve cost savings of up to USD 17,000 per year.

Precise, real savings values are available when looking at the machine dashboard. A sensor provides real-time data on the amount of steam circulating in the circuit, from which the corresponding reduction in CO2 equivalents can be calculated.

Utilizing the pressure drop
CASCADE reuses part of the invested process energy and uses the flash-steam in conjunction with the pressure ratios, which - nomen est omen - decrease in cascades in the different zones of the cylinder dryer.
The highest working pressure prevails in the first cylinder section. The heat transfer medium steam emits large amounts of energy for yarn drying and condenses without temperature loss.

The resulting hot condensate is not immediately discharged from the machine, but is instead fed into a flash tank, where vapor exhaust is formed as a result of the pressure reduction. In conventional systems, the carrier medium for gases is only created in the return line towards the boiler house and is eliminated as undesirable. Instead of being utilised in the process, it escapes into the environment. With the CASCADE system, this "freshly recycled steam" is used for the heat supply in the second cylinder section, but not without prior treatment.

In the system patented by KARL MAYER, the recycled steam is intelligently mixed with live steam and thus raised to the level of the required process conditions for use in the cylinder section at the end of the dryer. Here, the fabric moisture is reduced to the desired residual value at medium pressure and temperature conditions.

Market launch is underway
CASCADE was filed for patent by the KARL MAYER GROUP. It was published in September 2023.
The innovative solution at no extra charge was presented at ITM 2024 in Istanbul and was a visitor highlight at the KARL MAYER GROUP stand.

From January 2024, CASCADE will be part of the PROSIZE® as standard. The first sizing machine with the upgrade for greater energy efficiency will be delivered in the second quarter of this year. It will go to a manufacturer in Europe. In the next step, CASCADE will be integrated into other dryer types and will also be available for the BLUEDYE.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan will participate in the ITM 2024 International Textile Machinery Exhibition in Istanbul, Türkiye from 4th to 8th June 2024 with a full product lineup.

WHOLEGARMENT® knitting has recently gained heavy interest from the apparel industry due to the shrinking workforce of skilled sewing and linking personnel, as well as for its sustainable benefits by requiring the minimum amount of material to produce one item at a time. SHIMA SEIKI intends to gain even more interest with its new SWG-XR® flagship machine. SWG-XR® features the company's original SlideNeedle™on 4 needle beds for high quality production of WHOLEGARMENT® products using all needles, 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 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 before, 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 ITM will be shown in 15L. The MACH2®XS WHOLEGARMENT® knitting machine, also with original SlideNeedle™ on four needle beds, will be shown in 8L. Other WHOLEGARMENT® knitting machines include the MACH2®VS V-bed machine for producing WHOLEGARMENT® items using every other needle, shown in 8 and 18 gauges, as well as the compact SWG®091N2 for producing smaller WHOLEGARMENT® items and accessories, to be shown in 10 gauge. An economical proposal in V-bed WHOLEGARMENT® knitting will also be introduced in the form of the N.SVR®183 machine in 24 gauge.

SHIMA SEIKI’s technology in computerized shaped knitting is represented by its N.SVR®122 computerized flat knitting machine in 14 gauge, and features such innovations as the R2CARRIAGE®, WideGauge® knitting, spring-type moveable sinkers, DSCS® Digital Stitch Control System, stitch presser, yarn gripper and cutter, and takedown comb. Also on display will be the SCG®122SN coarse gauge machine in 3 gauge. Automatic seamless glove knitting machines will also be present, including the SFG®20 21-gauge machine, and SFG®-I in 10 gauge.

On the software side, demonstrations will be performed on SHIMA SEIKI’s SDS®-ONE APEX4 design system and APEXFiz® subscription-based design software. Each provides comprehensive support throughout the production 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 the way the design evaluation process is improved with ultra-realistic simulation capability, whereby virtual samples replace physical sampling, consequently reducing time, cost and material that otherwise go to waste. Digital prototyping using virtual samples on SDS®-ONE APEX4 and APEXFiz® help to digitally transform the fashion supply chain for realizing sustainable manufacturing. SHIMA KnitManager™ knit production management software will also be shown to demonstrate solutions for maximizing productivity through monitoring of machine status and production progress.

Breaking new ground in plastics recycling means assessing the value chain from end to end. The big opportunities for the future are in fine-tuning the individual process steps; from the collection of recyclable materials to the recycling process and the end product. This is where the cooperation of Lindner and the EREMA Group comes in, officially launched following the 50/50 founding of the holding BLUEONE Solutions in August 2023 to which shares of Lindner Washtech were contributed. The expertise of EREMA, a manufacturer of extruders and filtration solutions for plastics recycling and the largest company within the EREMA Group, has now been combined with the expert know-how from Lindner Washtech, a leading provider of all-in-one solutions for shredding, sorting and washing plastic feed materials.

Data transfer ensures more efficient recycling processes
Process control is an especially important aspect of plastics recycling, which is why standardising the process control system was what the two companies focused on first. "Together, we have developed a platform that allows data to be exchanged between the extruder and the washing system," says Manfred Hackl, CEO of the EREMA Group at IFAT in Munich. "This enables us to analyse the data more precisely so that effective improvement measures can be deduced." All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimise the washing process as soon as possible so that it can compensate for fluctuations in capacity and achieve a significant increase in output. This data transfer represents a new step on the roadmap to digitalization.

High efficiency due to smart energy management
"To ensure sustainable recycling, it is necessary to find the right process for each application and to make sure that the individual process steps are perfectly coordinated," emphasizes Michael Lackner, Managing Director of Lindner. Coordinating the process steps has already achieved initial success in energy management, and a clear example of this is heat recovery. "We use the latent heat generated during the extrusion process as an energy source for the washing and drying process," explains Lackner. "This enables our customers to sustainably reduce their energy costs and carbon emissions".

Making the most of synergies along the value chain
Synergies need to be used to establish the quality standards specified for each end application. "The key question is how we can improve the end product and increase the overall efficiency of the recycling process at the same time," agree Manfred Hackl and Michael Lackner. This will only work if companies work together along the value chain. The industry leaders can already point to several examples where together they have improved recycling processes and made it possible to move away from downcycling. "An example of this is the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using our two technologies," says Lackner. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.
