From the Sector

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.

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.

Monforts, which is celebrating its 140th anniversary this year, will exhibit a Montex stenter chamber with an integrated overhead heat recovery unit at the forthcoming ITM textile machinery exhibition in Istanbul from June 4-8.

The heat recovery unit on display at the stand of Monforts partner Neotek is just one of a range of energy saving options the company is now providing for both new and existing line installations.

Monforts Montex stenters and Thermex dyeing ranges are industry standard for the fabric finishing industry, providing many advantages in terms of production throughput and especially in energy efficiency and savings.

coaTTex
At ITM, Monforts will also introduce its latest coaTTex coating unit, dedicated to air knife and knife-over-roller coating. For single-sided application with paste or foam, the versatile coaTTex is suitable for both incorporation into existing finishing ranges as well as installation with new Monforts lines, especially Montex stenter systems.

UK-based textile testing solutions provider James Heal has launched two new instruments in its tensile and compression testing range, marking 25 years of innovation since their first Titan universal testing machine was developed in 1999.

Having seen sustained growth in the market for personal protective equipment (PPE), particularly safety workwear, equipment and footwear, James Heal designed the Titan 25 to meet demand for quality testing products that require higher capacity tests. In addition, the company has experienced increasing demand in testing solutions for wider sporting, industrial and transportation applications, which also influenced the decision to develop higher capacity test instrumentation.

The new Titan 25 is the highest capacity universal testing machine to join the range capable of tests up to 25kN, while the 10kN Titan 10 has been newly refined. The new instruments offer efficiencies through automation, quick change connections for tooling with compatibility across the range, upgraded software, plus enhanced safety features.

These dual column instruments enable testing on larger specimens across a wide range of tensile and compression tests. Load cells from 100N to 25kN allow testing to as low as 2N giving laboratories maximum flexibility and return for their investment.

Simple to use, the new Titan testers have over 750 pre-loaded standard procedures in the TestWise software, with the option for users to customise and save their own standards. The software automatically sets parameters for each selected test, reducing set up time and eliminating user error.

Cavitec, part of Santex Rimar Group, presents the redesigned Caviscreen at Techtextil Frankfurt. Caviscreen features latest technology for breathable laminates.

Caviscreen was developed as a hotmelt coating and laminating unit for breathable sportswear, rainwear and protective clothing – with and without applying a membrane. The redesigned machine shows a brand-new method to supply adhesive more evenly and precisely. Using PUR adhesive (polyurethane reactive adhesive) goes with additional benefits like strong bonding capabilities and versatility.

Caviscreen’s hotmelt screen printing is a special system for high-end application garments. With this Caviscreen system, a PUR adhesive is transferred onto the substrate through a rotary screen, similar to the well-established textile printing method. The adhesives are fed from the drum melter through a heated hose to the traversing adhesive distribution system inside the rotary screen, just behind the doctor blade.

The adhesive is pressed by the doctor blade through the screen holes and transferred to the substrate. Different dot pattern (mesh or irregularly) and different screen thicknesses allow different coating weight and adhesive coverages.

The traversing adhesive dispenser is used to distribute the adhesive automatically over the set working width that – an additional technical benefit – can be set without any mechanical changes.

Cavitec’s screen coating system achieves high bonding strength while using less adhesive than other coating processes, because of applying the coating on the surface of the substrate and like this, the adhesive has less tendency to penetrate the substrate.

Bonding strength, softness of the fabric and the breathability are defined by the coating weight and the coverage. The rotary screen allows users to regulate and adapt the coverage respectively the coating weight. Cavitec offers a large selection of screens that are essential to fulfil the fabric requirements. A further advantage is the ease and efficiency of switching from one screen to another by simply unlocking the bayonet fitting. The IR-heater cover opens pneumatically and the lightweight screen can be easily removed by hand. Unlike with other methods, there's no need to deal with hot oil or any other heated liquid that requires cooling down.

The Caviscreen technology supports manufacturers by reducing costs with screens priced at a mere fraction, just 10%, of common gravure roller prices.
