Flerlags tekstilmateriale til brug for forstærkningsarmering af tætningsbelægninger

摘要

The invention concerns a multilayer textile material useful in particular for armouring reinforcement of membrane roofing system, consisting of a complex comprising a textile grid embedded inside a textile structure consisting on non-woven laps arranged on either side of the grid, said laps being mutually linked by the entanglement of the lap fibres, resulting from the action of fluid (air water) jets, which drive the fibres through the grid and distribute them on either side thereof without damaging it, the two laps being made up of synthetic fibres. The invention is characterised in that: the grid is made with base of glass or polyester fibre; the textile laps arranged on either side of the grid are based on polyester fibres, at least one of these laps comprising 20 to 40 % of fibres selected from the family of fibres with high resistance to fire and heat.
