The agreement also strengthens the strategic partnership between the two companies that aims to develop spinning operations and achieve unprecedented levels of quality, productivity and efficiency.

DIW has placed an order for more than 700 of Rieter’s winding machines Autoconer X6. The winding machine serves as the final quality assurance in the ring spinning and compact-spinning process and is key to the performance of subsequent process steps. With its productivity, intelligent process automation, great splicing and winding quality, the Autoconer X6 is widely recognized in the market. The order will help DIW strengthen the vertical integration of its operations and accelerate its growth strategy in the cotton spinning industry, further underpinning its position in global markets. This order follows the initial batch placed in March 2024, when Rieter and DIW signed their first strategic partnership to develop intelligent yarn manufacturing technology that utilizes digitization and automation to minimize conversion costs and maximize value for customers.

Finishing machinery specialist Monforts will exhibit at the upcoming Febratex textile machinery exhibition taking place in Blumenau, Brazil, from August 20-23, along with Uniferro, its new regional partner.

This new alliance follows the retirement of Herbert Erdmann of the service agency Euro Texteis, who has worked with Monforts over more than 30 years to secure a leading position in the region for Montex stenter dryers, Thermex dyeing ranges and associated finishing technology.

With offices in Sao Paulo and Ceara and sub-agents across Brazil, Uniferro has been active in the textile industry for over 50 years.

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

A wide range of coatings can be applied to fabrics for providing functions such as waterproofing, liquid and gas protection and breathability, in addition to foam lamination and black-out coating.

Denim hub
Brazil remains a buoyant hub for textile manufacturing with a particular stength in the denim dyeing and finishing sector and many Monforts Thermex hotflue dyeing systems are already operational in the region, reaping the benefits of the Econtrol® process.

Econtrol® is a continuous process for the dyeing of woven cotton and cellulosic fabrics, especially denim, in which reactive dyestuffs are fixed into the fabric in a one-step dyeing and drying process with a controlled combination of steam and air. The entire pad-dry process takes just two-to-three minutes.

“Differentiation is the key in the highly-competitive denim fabrics industry, whether through the successful incorporation of new fibres, accommodating new fabric constructions or exploring the many options for how to treat them at the finishing stage, to gain a market advantage,” says says Monforts Regional Sales Manager Achim Gesser. “Our lines allow users to be extremely versatile and respond quickly to market demand, while also allowing very short production runs.”

Because finishing is a particularly energy-intensive part of the textile production chain, it is exactly where convincing results can be achieved, he adds, and Monforts has developed a wide range of energy-saving. These included a range of heat recovery systems, such as the Universal Energy Tower and the ECO Booster. Both can also be retrofitted to existing ranges to make production more resource-efficient and economical, yet without having to invest in a new machine.

“Energy costs tend to be high in Brazil and can account for up to 70% of production costs for our customers, so there is great demand for ways of saving money,” says Gesser. “Cutting energy usage also helps in terms of global warming and reducing carbon footprint, of course, so these latest technologies are a win-win for fabric finishers. As we look forward to a promising partnership with Uniferro in Brazil, we would like to extend our thanks and best wishes for the future to Herbert Erdmann for his hard work over the years.”

The first installations of the Trützschler Card TC 30i and the Trützschler Integrated Draw Frame IDF 3 are now complete – and the first customers have finished rigorous testing in direct spinning applications.

The Italian company Marchi & Fildi, headquartered in Biella, was one of the first to test the new IDF 3. The company specializes in producing pure and blended yarns made from natural or man-made fibers for flat knitting, circular knitting and weaving. Its products are used for fashion, furnishings and technical applications worldwide. It also places a strong focus on reducing its environmental impact.

Marchi & Fildi’s first trials were carried out with different fiber blends. This included a blend of 70 % soft waste cotton and 30 % polyester as the raw material for rotor direct spinning, with a yarn count in a range of Ne 8 to Ne 12 and Ne 30.
Later tests involved fiber blends of 50 % PET and 50 % recycled cotton from hard textile waste for rotor direct spinning with a yarn count of Ne 30. Experts at Marchi & Fildi stated that this material blend is typically very challenging. Processing secondary fibers made from hard textile waste requires very high competence in yarn production, which Marchi & Fildi impressively demonstrates. It also requires advanced technologies. This is due to technological challenges such as significantly lower fiber length. Trützschler’s IDF technology has a special drafting zone geometry that ensures reliable fiber guidance and controls floating fibers. It generates lower drafts than a conventional draw frame passage and avoids the risk of false drafts and count variations.

Decades of experience with the IDF technology have demonstrated that the higher the short fiber content, the better the result with IDF compared to conventional two draw frame passages. In combination with the TC 30Ri, a variant of TC 30i that has been specifically equipped and configured for processing recycled fibers, the IDF 3 delivers maximum possible quality for the production of sustainable yarns.

Overall, the company’s results showed a 75 % increase in productivity over the previous card model and a 14 % reduction in energy consumption at higher production rates. Combining the TC 30Ri and IDF 3 also enabled Marchi & Fildi to skip the drawing stage from its process, which boosts quality while saving resources and cutting costs.

KARL MAYER Technische Textilien launches the new MAX GLASS ECO, a composite machine with a focus on standard non-crimp fabrics made of glass fibers.

The MAX GLASS ECO incorporates proven solutions from the KARL MAYER GROUP's range of multiaxial machines, including features from its predecessor, the MAXTRONIC®, and combines these with sophisticated new technical developments. The result is a production machine for the economical manufacture of standard glass fiber articles, especially non-crimp fabrics for the wind power industry.

The multiaxial warp knitting machine is extremely efficient, affordable and, unlike the previous MAXTRONIC®, sufficiently flexible thanks to various optional functions. At a rotational speed of up to 1,800 min^-1, a maximum output of 410 m/h is achieved.

The MAX GLASS ECO is available with a working width of 101″ and is suitable for laying angles of +/-45°. A complementary layering system ensures a uniform take-up speed and therefore gentle processing of the fiber material. This sophisticated weft tension compensation device is one of a whole series of tried and tested features of KARL MAYER multiaxial technology that have been integrated into the new machine. Other adopted solutions include the Fiber Chopping Unit, which allows glass fiber chips to be introduced into the laying process and thus cover more fields of application, and a single pin transport chain for a processing method with less waste.

Newly developed innovations also ensure even better performance, including the fixed layer system, which ensures high placement precision at all laying angles. Other equipment details with added value for the customer include a conveyor belt across the full working width, the walking needle system, which prevents the formation of lanes even with long stitch lengths, and the fitting of single compound needles, which can be changed efficiently.
