From the Sector

Monforts' new Montex 8500 stenter line was recently installed at Curt Bauer’s plant in Aue in Germany.

Curt Bauer has been in continuous operation for 150 years, beginning as a weaving mill in Aue in the Ore Mountains region of Saxony back in 1882. Today, with 120 employees, the company has an annual production of 2.2 million metres of fabric and specialises in three key fields – home textiles, special damask fabrics for West African garments and technical textiles.

A first Montex stenter was installed by Monforts at the Aue plant in 2003 and an older machine from a third party supplier was also still in operation prior to the latest upgrade.
“The replacement of our older existing stenter, which was installed in 1985, was long overdue,” explains Gert Bauer. “It had a maximum working width of 2.2 metres and we were looking to both increase productivity and reduce energy requirements.”

As a consequence, the company opted for a new Montex 8500 line with a working width of 3.2 metres equipped with the MonforClean heat recovery and exhaust air purification system. The Montex stenter remains unmatched in terms of its robustness and long service life and with MonforClean technology, the waste heat from the drying process is used to pre-heat the drying air. This results in a radical reduction in the conventional heat supply required, compared to full gas and thermal oil heating. Overall energy savings of up to 40% can now be achieved compared to conventional stenters.

The first challenge at the Aue plant was how to fit the significantly larger machine into the available space without restricting the area required for docking operations.

The special multi-level configuration that Monforts designers and Curt Bauer’s team devised in order to meet these requirements involved raising all of the line’s drying zones – with a combined length of over 28 metres – on scaffolding platforms, to enable the ground floor space below them to continue to be fully utilised.

The next challenge involved configuring the MonforClean system without having to make any costly changes to the roofing structure. This, Gert Bauer observes, demanded “millimetre precision”.

With the new line now fully operational, the savings it is providing have yet to be fully calculated.

• Long-term partnership between the Austrian textile producer FEINJERSEY and the German textile machinery manufacturer BRÜCKNER

The Feinjersey Group is an internationally operating textile company and supplies the "global players" of the textile industry worldwide. The value chain of the company, which is based in Götzis, Austria, ranges from yarn processing to the finished product.

As a fully integrated production company, the internationally active textile company Feinjersey attaches great importance to a high quality standard and guarantees care at every step in the process chain. With approx. 250 employees and annual sales of around 45 million euros, the company knits, dyes and finishes top-quality knitted fabrics as well as elastic woven fabrics for a wide range of applications.

Products are made for the fashion, sports, workwear and technical textiles sectors. Among other things, fabrics for the automotive industry, laminating backings and coating substrate for artificial leather or foils, construction textiles or fabrics for medical technology are all produced.

The Austrian textile manufacturer has been certified with the Bluesign textile seal and ensures efficient use of resources with modern machinery. Water and energy consumption as well as pollutant emissions are to be reduced to a minimum.

In textile finishing in particular, the focus is on minimising energy consumption as this process is the most energy-intensive in the entire process chain. Feinjersey uses its own photovoltaic system for this purpose, as well as the heat recovery and exhaust air purification systems on the stenter frames. By using the waste heat from production, the company's buildings are heated. All six stenter frames at Feinjersey are made by BRÜCKNER and produce with three-stage heat recovery and exhaust air purification systems.

The latest BRÜCKNER line has a working width of 4.20 m and is mainly used for the finishing of high-ly elastic and extremely sensitive knitted fabric. In order to avoid yellowing on the fabric, the stenter is equipped with an indirect gas heating system. The knitting oil vapours coming from the fabric during the heat-setting process are extracted from the dryer and cleaned in a BRÜCK-NER ECO-AIR exhaust air cleaning system before being extracted to atmosphere. The complete exhaust air treat-ment on the newest stenter is carried out by a multistage BRÜCKNER ECO-HEAT and ECO-AIR system.
