Abstract
A reinforced textile support, particularly for bituminous membranes, made of at least one layer of polyester non woven web and continuous high modulus reinforcement yarns longitudinally set with respect to said layer. The reinforcement yarns consist of cellulosic fibre multi-filaments of the Lyocell type. The assembly is bound by mechanical needling or water entangling, stabilised by means of thermal treatment at a temperature of 200-250° C. and consolidated by means of a chemical binder.
Claims20
Reinforced textile support, particularly for bituminous membranes, comprising at least one layer of non woven web of synthetic fibers, and continuous high modulus reinforcement yarns longitudinally set in respect of said layer, the reinforcement yarns having a Young modulus equal to or higher than 5 Gpa, preferably equal to or higher than 20 Gpa, characterized in that said reinforcement yarns consist of filaments of cellulosic nature.
