Resistance aux flammes

For fireproof and protective textiles

Flame protection is necessary for protecting workers in various industrial sectors, but also for some public-sector employees. FilSpecTM uses various combinations of fibres to offer solutions adapted to the various applications of the textiles produced by its clients.

Triple protection yarn Firefil

Once again, FilSpecTM innovates by launching FireFilTM, a fibreglass core yarn that is flame resistant, cut resistant and tear resistant.

Textiles created from this yarn exceed the highest standards of the fire-resistant fabric industry, offering triple protection to firefighters and industrial workers exposed to various dangers.

An ingenious design

Thanks to an innovative spinning technology, a highly flame-resistant fibreglass filament is inserted in the centre of the yarn. The outer layer of this yarn, made of high-performance textile fibre, is carefully chosen so as to render the composite yarn more effective.

The fibreglass core yarn is then woven to create a FireFilTM fabric that is flame resistant, cut resistant and tear resistant.

FireFil Welding

FireFilTM has been adapted to meet the specific needs of welders exposed to sparks and molten-hot metal shavings.

FireFilTM Welding is a coated glass-core yarn designed to both protect welders and improve their comfort.

With its moisture-wicking properties, the fabric made with FireFilTM feels comfortable against the skin and can be used to produce coveralls or protective aprons.

“My coveralls are light and comfortable. I’ve worn them in a lot of different conditions and they passed the test every time. They’re much more breathable than my old coveralls, which will be
