From the Sector

Monforts will highlight its technologies for special technical textile applications at this year’s ITMA ASIA + CITME which takes place at the National Exhibition and Convention Center in Shanghai, China, from November 20-24.

One of Monforts' developments is the Montex 8500 XXL stenter system for the production of technical fabrics in widths of up to 6.8 metres. Among the products made on this system are treated nonwovens for the geotextiles and filter media markets, tarpaulins, advertising banners, black-out curtains, membranes and many more.

On Montex©Coat coating lines, meanwhile, the possibilities range from the single-sided application of finishing agents for outdoor clothing and adding functionality to home textiles, to the creation of materials for sophisticated lightweight construction and automotive and aerospace components.

“Many more applications are possible, such as the overdyeing of denim, the creation of double-face coated materials, fabrics awnings, tents and medical drapes and the pre-treatment of substrates for digital printing”, explains Gunnar Meyer, Monforts area sales manager for China. “A range of different doctor blades and their combinations can be supplied to meet individual requirements, including air knife, roller knife, foam, screen and magnetic roller coating. The latter option is recommended for lines with working widths of over 2.4 metres.”

In addition, Monforts can provide the necessary explosion-proof ranges for solvent-based coatings and high temperature processes up to 320°C, such as the PTFE coating of nonwoven filter material. These lines are equipped with special burners, stenter chains, and insulation.

Monforts will highlight its advanced finishing and coating technologies for the production of technical textiles at Techtextil North America, which takes place at the Georgia World Congress Center in Atlanta from May 17-19.

The company and its US representative PSP Marketing, of Charlotte, North Carolina, will be part of the centrepiece VDMA German Pavilion at the show.

Energy prices
With energy prices continuing to go through the roof, an emphasis at Techtextil North America will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as the MonforClean system, in which 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. A range of further resource-saving and energy recovery options can be specified per individual line installation.

Advanced machine operation
With the highly intuitive 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.

Versatility is the key
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.

• Gorilla Protect is a new company formed in May this year to promote the Catus face mask – a major leap forward in the effectiveness of personal protection products that are available to consumers in the fight against Covid-19.
• Behind Catus and the new company is Nova Textil, the established fabric finishing company based in Grefrath, Germany, and now run by father and son team Rainer and Oliver Hurtz.

Single stenter

Rainer Hurtz founded Nova Textil with a single Monforts Montex stenter and just five employees in 1999 and has steered its constant development and growth over the past twenty years.

“Our initial focus was on the coating of mainly glass fibre fabrics, awnings and sun protection products for outdoor furnishings,” he said. “We had a great customer who was providing us with so many orders that by 2005 we took the decision to order a second Montex stenter, in a special configuration. This also allowed us to enter the market for blackout and digital printing fabrics. We’ve had a great ongoing relationship with Monforts from the beginning.”

A third Montex stenter line was installed at the company’s Grefrath plant in 2015, by which time the company had grown to 40 people and a major new market had opened up in the supply of fabrics for promotional materials at exhibitions and trade shows.

“We had a fantastic two years in 2018 and 2019 and everything was going great for the first three months of this year, but in April it all came crashing down,” said Oliver Hurtz. “Coronavirus put an end to trade shows in 2020, which had a very serious impact on our business.”

At the same time, however, the company was exploring the potential of a new biocidal product from one of its chemicals suppliers which has both antiviral and antimicrobial properties.

Filtration

“We had already been producing coated fabrics for hot gas filtration and realised that in combination with this new microporous coating we had the basis for a very effective single-layer face mask,” Rainer said. “Achieving this with a single layer product rather than the usual three has resulted in a significant advance in comfort for the wearer and because the mask is able to disinfect itself and helps regulate humidity, it can be worn a number of times without needing to be washed, for greater convenience. It only needs to be washed when it gets dirty and can also be washed up to twenty times without losing its properties, which has to be preferable to single-use disposables.”

Catus face masks are based on 100% woven cotton and the active ingredients in the finish are a reaction mass of titanium dioxide and silver chloride certified to ISO 20743 for their antibacterial effect, and to ISO 18184 for their antiviral effect.

They are proven to  eliminate over  99.99% of the human coronavirus 229 E, with the multiplication of microorganisms such as germs and bacteria prevented by the biostatic action of silver salts and viruses destroyed by oxygen-releasing substances and a mechanism that attacks their fatty envelope. The virus membrane loses its cholesterol content and the virus is inactivated.

Colours

Gorilla Protect next plans to make the masks available in four colours – black, Bordeaux, olive and grey – and is also working on colour branding and printing labels.

“It’s not possible to print on the surface of the mask after it has been coated, but its is possible for volume orders to be printed before the treatment,” Oliver Hurtz said.

“Face masks are going to become an established part of life in the West like they are in Asia and need to be as comfortable and convenient as possible for the wearer,” his father concluded. “With these things in mind, we believe Catus is a significant step forward.”
