From the Sector

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.”

Over 600 delegates from 58 countries subscribed to the latest VDMA textile machinery webinar on sustainable dyeing held on February 3rd, 2022 – a record since the monthly online series started in June 2020. The webinar, entitled ‘Resource-saving in Textile Processing – Continuous Dyeing and Washing’, involved the three companies Monforts, DyStar® and Goller.

In outlining the capabilities of Monforts Thermex hotflue lines for the Econtrol® continuous dyeing process, the company’s Textile Technologies Engineer Jonas Beisel observed that the current industry focus is very much on cleaner processes and products in accordance with the Corporate Social Responsibility (CSR) commitments of the major fashion brands, and with further regulations to be expected.

Cellulosics
Econtrol® is a continuous process for the dyeing of woven cellulosic fabrics that has already been well proven on the market, with over 150 Monforts Thermex lines already in operation at mills worldwide.

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 at a temperature of between 120-130°C and a relative humidity volume of 25-30%.

Benefits
The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step.

Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

Complementary services and systems
Complementing the Monforts presentation during the webinar, Bertram Seuthe, Global Business Development Manager at DyStar, outlined the importance of specific Levafix® /Remazol® reactive dyes and Dianix® disperse dyes for sustainable dyeing processes such as Econtrol®, Cadira® Continuous and CPB knit. In these processes Sera® auxiliaries are also employed for optimised wash-off results.

Guido Seiler, Area Sales Manager at Fong's Europe, also introduced the latest developments of the Goller brand for the washing process, which can reduce water consumption by between 10 to 20%, as well as reductions in both heating energy and waste generation, depending on the specific fabric construction and required shade.
