A special Montex gas powered stenter line with heat recovery for added efficiency has been supplied to Germany’s BWF Protec by Monforts.
Based in Hof, Germany, BWF Protec is involved in so many industrial niche markets its range of needlepunched materials is perhaps the widest available from any single source. As a consequence, a very versatile and unique Montex stenter solution was needed to meet all requirements.
“We are not making commodities of thousands of square metres,” explained BWF Protec managing director, Dieter A. Huber, “Our business is small quantities of usually very high performance materials for special niches.
“We have five product managers who are all specialised textile engineers and follow industrial developments around the world to identify areas where a customised needlefelt solution would be appropriate. Where it is, we can provide it.”
Industries supplied with materials by the company range from the aerospace, automotive and transportation sectors to aluminium, glass and steel plants and on to the furniture, protective clothing, medical equipment and grinding and polishing markets.
BWF Protec nonwovens are manufactured in thicknesses of 1mm to 25mm, in widths of 50 cm to 260 cm and in fabric weights of 100 gsm up to 5,500 gsm.
The staple fibres which are processed include all natural and conventional synthetics, in addition to high value performance fibres such as Conex, Twaron, Pyron, Kermel, Basofil, P84, Kynol, PTFE and Zylon. The company even manufactures certain products with Bekinox stainless steel fibres.
This is in addition to many special blends, all of which are carded pre-needled and then finish needled prior to reaching the stenter.
“Due to this extremely wide range, an off-the-shelf system was not enough,” Mr Huber explains. “We required an ‘all-singing and all-dancing’ solution, and Monforts didn’t disappoint with the specially customised machine model they delivered.”
The Montex 6500 8F Twin Air system has eight three-metre chamber compartments and a total length of 53 metres.
