Mayer & Cie. at ITM

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.

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.

Recycled fibres: Swiss manufacturers for circularity

Many end-users now expect recycled materials to be in textile products they purchase – and this is driving innovation throughout the industry. However, there are still many technical and economic issues facing yarn and fabric producers using recycled resources. Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Members of the Swiss Textile Machinery Association offer some effective solutions to these challenges.

Synthetic recycled materials such as PET can usually be treated similarly to new yarn, but there are additional complexities where natural fibres like wool and cotton are involved. Today, there’s a trend towards mechanically recycled wool and cotton fibres.

Spinning recycled cotton
The use of mechanically recycled fibres in spinning brings specific quality considerations: they have higher levels of short fibres and neps – and may often be colored, particularly if post-consumer material is used. It’s also true that recycled yarns have limitations in terms of fineness. The Uster Statistics 2023 edition features an extended range of fibre data, supporting sustainability goals, including benchmarks for blends of virgin and recycled cotton.
In general, short fibres such as those in recycled material can easily be handled by rotor spinning machines. For ring spinning, the shorter the fibres, the more difficult it is to guide them through the drafting zone to integrate them into the yarn body. Still, for wider yarn counts and higher yarn quality, the focus is now shifting to ring spinning. The presence of short fibres is a challenge, but Rieter offers solutions to address this issue.

Knitting recycled wool
For recycling, wool fibres undergo mechanical procedures such as shredding, cutting, and re-spinning, influencing the quality and characteristics of the resulting yarn. These operations remove the natural scales and variations in fibre length of the wool, causing a decrease in the overall strength and durability of the recycled yarn. This makes the yarn more prone to breakage, especially under the tension exerted during knitting.

Adapting to process recycled materials often requires adjustments to existing machinery. Knitting machines must be equipped with positive yarn suppliers to control fibre tension. Steiger engages in continuous testing of new yarns on the market, to check their suitability for processing on knitting machines. For satisfactory quality, the challenges intensify, with natural yarns requiring careful consideration and adaptation in the knitting processes.

From fibres to nonwovens
Nonwovens technology was born partly from the idea of recycling to reduce manufacturing costs and to process textile waste and previously unusable materials into fabric structures. Nonwovens production lines, where fibre webs are bonded mechanically, thermally or chemically, can easily process almost all mechanically and chemically recycled fibres.

Autefa Solutions offers nonwovens lines from a single source, enabling products such as liners, wipes, wadding and insulation to be produced in a true closed loop. Fibres are often used up to four times for one product.

Recycling: total strategy
Great services, technology and machines from members of Swiss Textile Machinery support the efforts of the circular economy to process recycled fibres. The machines incorporate the know-how of several decades, with the innovative power and quality standards in production and materials.
Stäubli’s global ESG (environmental, social & governance) strategy defines KPIs in the context of energy consumption, machine longevity and the recycling capacity in production units worldwide, as well in terms of machinery recyclability. The machine recyclability of automatic drawing in machines, weaving systems and jacquard machines ranges from 96 to 99%.

Iluna Group with sustainable Collection at Interfilière Paris

As the role of lingerie in fashion and athleisure continues to augment, the desire for garments that will meet a new set of values for contemporary consumer lifestyles will flourish. Iluna Group comes back to Interfilière Paris with an important goal: to relaunch the qualities and dimensions of sustainability.

Iluna’s new path begins with the investment in the renewal of machines, which allow it to fly higher in terms of high-tech developments, quality, definition, effects of yarns and patterns. The journey into the new dimension of responsible quality continues with ad hoc developments in the field of GRS (Global Recycled Standard) certified recycled yarns, aimed at unprecedented effects both in look, in performance and in the hands of fabrics. The cord yarn is a precious yarn with a ROICA™ EF premium stretch yarn core, GRS certified and developed with 50% of pre-consumer waste materials content - double, covered with an equally recycled shiny thread; the bright and translucent is instead to add brilliant effects so far not possible with a GRS yarn.
