From the Sector

The Techtextil and Heimtextil Summer Special exhibitions, taking place together in Frankfurt from June 21-24, represent an opportunity for Monforts to showcase its finishing and coating technologies for two of its major markets – especially at a time when energy prices continue to soar for textile manufacturers in Europe.

Existing customers of Monforts include many manufacturers in the field of home textiles, as well as those making geotextiles, automotive fabrics and other functional materials – all of whom will be well represented in Frankfurt this June. Dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics, as well as high-temperature filter materials.

Energy prices are rising steeply everywhere and a particular emphasis for Monforts in Frankfurt will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as better insulation of the treatment chambers or the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air resulting in a radical reduction in the conventional heat supply required compared to gas and thermal oil heating. The modular system for heat recovery can also be extended for exhaust air cleaning and odour elimination. Monforts can provide a range of further resource-saving and energy recovery options tailored to each individual line installation including modification of the heating source.

With the Qualitex 800 visualization software, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

All of these very different materials require coating and finishing for maximum efficiency, using Monforts technologies which provide the ultimate in flexibility and the ability to switch quickly from one fabric run to the next, without compromising on the economical use of energy or raw materials.

The Monforts EcoApplicator offers further potential for sustainably achieving perfect finishes via a precise direct application system, as an alternative to conventional padding – where fabrics are immersed in a bath of the required finishing chemicals. It can significantly further reduce the energy and water required and finishes can be applied on just one side of the fabric, or both, and even separately on each side, to be sealed in place via different heating zones in the stenter.

Albarrie – a major player in North America’s industrial nonwovens industry – is now benefiting from one of the first Monforts Montex stenter installations equipped with the full range of MonforClean heat recovery and exhaust air purification technologies.

With the new three-chamber Montex stenter at its plant in Barrie, Ontario, the Canadian company is treating specialised needlepunched nonwovens up to 4mm thick. These have applications in a wide range of filter media and performance fabrics.

The new Montex is enabling Albarrie to heat set and dry its materials to produce denser, higher quality fabrics which can also be finished and delivered to customers more rapidly.

Across timezones
It took a crew of skilled millwrights, electricians and product specialists to build the line which was delivered in 11 shipping containers to Albarrie’s production facility. The line was originally scheduled to be fully operational in the Spring of 2020, but the ongoing global Covid-19 pandemic inevitably led to several delays during the start-up and commissioning process.

Energy savings
The Albarrie Montex line’s MonforClean capabilities include an air-to-air cross flow heat exchanger and an electrostatic precipitator providing the ability to purify the exhaust air and to recover energy to a maximum of 22,500 cubic metres of air per hour, resulting in a radical reduction in the conventional heat supply required. The MonforClean was developed in cooperation with partner KMA Umwelttechnik, based in Königswinter, Germany.

The fully automated system is powered by a Siemens SPS S7 controller and KP 700 touch panel from which the recycled energy can be continuously monitored and savings calculated.

The three-chamber Montex stenter is fitted with the latest Monforts Qualitex 800 PLC control system with WebUI, providing ease of operation, a full operating cost overview and maintenance monitoring.
